When the width of the convex streak portion is W _a and the width of the concave streak portion is W _b and W _a / W _b is the duty ratio, the above-mentioned decorative material has a higher duty ratio of height H of the convex streak portion. May be configured to include a pattern having a smaller relationship.

The width of the convex linear portion may be less than 30 μm.

In addition, when the width of the convex streak portion is W _a and the height of the convex streak portion is H, H / W _a may be configured to be larger than one.

Another aspect of the present invention is a cosmetic material having a pattern formed on the surface, wherein the pattern is a form in which a plurality of convex streaks and a plurality of concave streaks are alternately arranged, and the convex streaks It is a cosmetic comprising a plurality of areas in which at least one of the height, width, pitch and extension direction of the parts is different, and between adjacent areas, boundary means consisting of convex or concave lines are formed.

Hereinafter, the present invention will be described based on the embodiments shown in the drawings. However, the present invention is not limited to these embodiments. In the drawings shown below, the sizes and proportions of members may be changed or exaggerated for ease of understanding. In addition, in order to make it easy to view, illustration of unnecessary parts in the description and reference numerals that are repeated may be omitted.

FIG. 1: is the figure (plan view) which expanded a part of decorative material 10 concerning 1st form, and was planarly viewed from the pattern formation layer 12 side. In FIG. 1, for convenience, arrows (x, y, z) indicating directions, that is, coordinate systems are also shown. Here, the xy direction is the in-plane direction of the surface of the cosmetic 10, and the z direction is the thickness direction, and also the normal direction of the xy plane representing the spread of the in-plane direction of the cosmetic. Accordingly, FIG. 1 is a view of the cosmetic material 10 as viewed from the z direction which is the pattern forming layer 12 side. The observation of the cosmetic material from the thickness direction (z direction) of the cosmetic material as shown in FIG. 1 is also referred to as a plan view and a plan view showing a plan view.
As can be seen from FIG. 1, in the cosmetic material 10 of the present embodiment, asperities by the pattern forming layer 12 are formed on the surface side that can be touched by human eyes and hands.

Further, as can be seen from FIG. 1, in the decorative material 10, the unit areas 13 which are areas of a regular hexagon are two-dimensionally arrayed in the xy direction in a two-dimensional view. For easy understanding, one unit area 13 is outlined with a thick line in FIG.
The unit region referred to here is a repeating unit, that is, in a plane (xy plane), a plane is repeatedly arranged adjacently in a direction having translational symmetry (direction orthogonal to three pairs of opposite sides). It means an area that becomes a unit that can be coated.

FIG. 2 shows an enlarged view of one unit area 13 extracted from FIG. As can be seen from FIG. 2, the unit region 13 is further divided into ten regions of a plurality of individual regions 14 to individual regions 23, and a concavo-convex pattern is formed on the individual regions 14 to 23 respectively.
In the decorative material 10 of this embodiment, unit areas 13 as repeating units are arranged, and in this unit area 13, individual areas 14 to 23 each having a concavo-convex pattern are formed. However, there may be no unit area as such a repeating unit, and a plurality of individual areas may be formed on the whole. Further, in the present embodiment, there are two types of regions, and they are referred to as “unit region” and “individual region” for easy understanding, but they can be generically expressed as “regions”.

1 and 2, a dotted line is shown in part, but the dotted line is a line which does not actually exist, and is an imaginary line provided to make it easy to understand the boundaries of the unit area and the individual area. As can be seen from FIG. 1, in the present embodiment, the unit area 13 is a regular hexagon, and in the unit area 13, each of the individual areas 14 to 23 is a triangle.

FIGS. 3A to 3C show the cross-sectional shapes of the three individual areas 14, the individual areas 15, and the individual areas 16 among the individual areas 14 to 23. This cross section is a thickness direction (z direction) cross section perpendicular to the direction in which the ridges of the convex linear portions formed in the individual regions extend.
As can be seen from FIGS. 3 (a) to 3 (c), the decorative material 10 is configured to have a base 11 and a pattern forming layer 12 laminated on one surface of the base 11. The pattern forming layer 12 forms the shapes of the unit area 13 and the individual area 14 to the individual area 23.

The base 11 is a sheet-like member having a function of supporting the pattern forming layer 12 and imparting strength to the decorative material 10. The base material 11 is not particularly limited as long as it has the same function as a conventionally known cosmetic material. For example, as the material of the substrate, usually, polyolefin resins such as polyethylene, polypropylene, olefin thermoplastic elastomer, ionomer, acrylic resins such as polymethyl methacrylate and polybutyl methacrylate, thermoplastic resins such as polyethylene terephthalate and polybutylene terephthalate Thermoplastic resins such as polyester resin, thermoplastic urethane resin, vinyl chloride resin, ABS resin (acrylonitrile-butadiene-styrene copolymer), styrene resin etc., melamine resin, unsaturated polyester resin, two-part curing urethane resin etc. A curable resin, or an ionizing radiation curable resin or the like which is cured by ionizing radiation (ultraviolet light, electron beam or the like) of a radical polymerization type acrylate type or cationic polymerization type epoxy type is used. In addition, when the material of a base material is resin, you may color with a well-known coloring agent. Other than this, paper, non-woven fabric, metal, wood and the like may be used in the form of a sheet, a plate, a three-dimensional object, etc., appropriately laminated with the above resin material.

The thickness of the substrate is not particularly limited, but in the case of a sheet-like substrate or a film-like substrate, for example, the thickness is about 20 μm or more and about 1000 μm or less, and in the case of a plate-like substrate, for example, 1 mm or more and 20 mm or less A degree of thing is used.

The pattern forming layer 12 is a layer having asperities laminated on one surface of the base material 11, and the asperities have a predetermined shape as in the unit area 13 and the individual area 14 to the individual area 23, and the asperity pattern is formed. Are configured. In the present embodiment, the pattern forming layer 12 has the following configuration.

As described above, in the present embodiment, the pattern forming layer 12 has unit areas 13 of a regular hexagon in a plan view of the decorative material 10, and a plurality of unit areas 13 are two-dimensionally arranged in the xy plane to be an entire plane. Is covered. Then, each unit area 13 is divided into a plurality of individual areas 14 to individual areas 23, and each uneven area is formed for each individual area. The individual areas 14, 15, 16 will be described below as an example.

As can be seen from FIG. 2 and FIG. 3A, the individual region 14 is formed with a concavo-convex pattern, and the concavo-convex pattern is an array of convex linear streaks 14 a and concave streaks 14 b arranged alternately. It will be done.
The convex linear portion 14a is a rectangle having a height H _14a and a width W _{14a in} the cross section shown in FIG. 3 (a). The convex linear portion 14a has this cross section, and is configured such that ridge lines extend in a direction different from the arrangement direction (for example, a direction orthogonal to the arrangement direction). The length to which the convex linear portion 14 a extends is determined by the contour shape of the individual area 14.
Similarly, the concave streak portion 14b is a rectangle having a depth D _14b and a width W _{14b in} the cross section shown in FIG. 3 (a). The concave streak portion 14b is configured to have this cross section and to extend in a direction different from the arrangement direction (for example, a direction perpendicular to the arrangement direction, parallel to the convex streak portion 14a). The length to which the concave linear portion 14 b extends is determined by the contour shape of the individual area 14.
Therefore, the pitch P ₁₄ of the convex linear portion 14 a and the concave linear portion 14 b can be obtained by the sum of W _{14 a} and W _{14 b} .

Here, the size of W _14a , W _14b , H _14a , and D _14b is not particularly limited, but it is preferable to be fine from the viewpoint of forming the pattern of the cosmetic material, and in this embodiment, It is preferable that 1 μm ≦ W _14a ≦ 1000 μm, 1 μm ≦ W _{14 b} ≦ 1000 μm, 3 μm ≦ H _{14 a} ≦ 3000 μm, 3 μm ≦ D _{14 b} ≦ 3000 μm.

Further, it is preferable that H _{14 a} / W _{14 a} (also referred to as an aspect ratio), which is the ratio of height to width in the convex streak portion 14 a, be larger than one. According to this, the texture of the cosmetic material can be made more new. However, when the aspect ratio is too large, the degree of difficulty in mold production increases, and stress on the concavo-convex pattern is concentrated and easily damaged when external force is applied to the mold and the cosmetic material. Therefore, H _14a / W _14a is usually 5 or less, preferably 3 or less.

In addition, although the cross-sectional shape of the convex filament part 14a of this form is a rectangle, it may be another form, without being limited to this. This includes, for example, a trapezoidal shape, a shape having a semicircular tip, and a shape in which an R is formed at the protruding corner portion. Since the concave streaks 14b are formed between two adjacent convex streaks 14a, the cross-sectional shape is determined by the shape of the convex streaks 14a. The same applies to the convex streaks and concave streaks in other individual regions.
Here, for the width of the convex streak portion, the width at the center in the height direction is taken as the width of the convex streak portion. Similarly, for the width of the concave linear portion, the width at the center in the depth direction is the width of the concave linear portion.

The material which forms the pattern formation layer 12 can use suitably the normal material used for a makeup material. The pattern forming layer 12 is formed of the same material as the substrate 11 if the substrate is heated and softened to press the mold (embossed plate). Further, if the pattern forming layer 12 is laminated on the base material 11 as a separate layer from the base material 11, the same as the base material 11 prepared separately from the base material 11 from the viewpoint of curing the molten composition after molding. Resins can be used.

The individual area 15 is an individual area adjacent to the individual area 14, and a concavo-convex pattern is formed as can be seen from FIG. 2 and FIG. 3 (b). The uneven pattern is formed by alternately arranging convex linear streaks 15a and concave linear streaks 15b in a line shape.
The convex linear portion 15a is a rectangle having a height H _15a and a width W _{15a in} the cross section shown in FIG. 3 (b). The convex linear portion 15a has this cross section, and the ridge line is in a direction different from the arranging direction (for example, a direction orthogonal to the arranging direction) and a direction different from the extending direction of the convex linear portion 14a of the individual region It is configured to extend to The length by which the convex linear portion 15 a extends is determined by the contour shape of the individual area 15.
The concave streak portion 15b is a rectangle having a depth D _15b and a width W _{15b in} the cross section shown in FIG. 3 (b). The concave streak portion 15b is configured to have this cross section and to extend in a direction different from the arrangement direction (for example, a direction perpendicular to the arrangement direction, parallel to the convex streak portion 15a). The length to which the concave linear portion 15 b extends is determined by the contour shape of the individual area 15.
Thus the pitch _{P 15} of the convex linear portions 15a and凹線strip portion 15b can be obtained by the sum of the _{W 15a} and _{W 15b.}

Here, preferable ranges of the height H _15a , the depth D _15b , the width W _15a , and the width W _{15b in} the individual area 15 can be considered in the same manner as the individual area 14. In addition to this, in the individual area 15, H _{14 a} > H ₁₅ a in relation to the individual area 14. Further, in the present embodiment, the individual regions 15 are set to _satisfy D _{14 b} > D _{15 b} , W _{14 a} = W _{15 a} , W _{14 b} <W _{15 b} , and P ₁₄ <P ₁₅ .

The individual area 16 is also an individual area adjacent to the individual area 14, and a concavo-convex pattern is formed as can be seen from FIG. 2 and FIG. 3 (c). The uneven pattern is formed by alternately arranging convex linear streaks 16a and concave linear streaks 16b in the shape of a straight line.
The convex linear portion 16a is a rectangle having a height H _16a and a width W _{16a in} the cross section shown in FIG. 3 (c). The convex linear portion 16a has this cross section, and the ridge line is in a direction different from the arranging direction (for example, a direction orthogonal to the arranging direction) and a direction different from the extending direction of the convex linear portion 14a of the individual region 14 It is configured to extend to The length to which the convex linear portion 16 a extends is determined by the contour shape of the individual area 16.
The concave streak portion 16b is a rectangle having a depth D _16b and a width W _{16b in} the cross section shown in FIG. 3 (c). The concave streak portion 16 b has this cross section and is configured to extend in a direction different from the arrangement direction (for example, a direction perpendicular to the arrangement direction, parallel to the convex streak portion 16 a). The length to which the concave linear portion 16 b extends is determined by the contour shape of the individual area 16.
Accordingly, the pitch P ₁₆ of the convex linear portion 16 a and the concave linear portion 16 _b can be obtained by the sum of W _{16 a} and W _{16 b} .

Here, preferable ranges of the height H _16a , the depth D _16b , the width W _16a , and the width W _{16b in} the individual area 16 can be considered in the same manner as the individual area 14. In addition to this, in the individual region 16, H _{14 a} > H ₁₆ a. Furthermore, in the present embodiment, the individual regions 16 are set to _satisfy D _{14 b} > D _{16 b} , W _{14 a} <W _{16 a} , W _{14 b} <W _{16 b} , and P ₁₅ = P ₁₆ .

The same holds true for the other individual regions 17 to 23. It is preferable that at least one of the height, width, and extending direction of the convex linear portion be different from the adjacent individual regions.
As a result, the pattern forming layer 12 can express unique texture different from before.

Among these, in the present embodiment, the heights of the convex streaks are different among the plurality of regions (regions as a general term of the regions present in the pattern forming layer regardless of the unit regions and the individual regions). Preferably, a region is included. By including a plurality of regions having different heights in this manner, it is possible to enhance the variety of expression of texture different from the conventional one.

Here, in order to make the heights of the convex streaks different among the regions as described above, the following may be performed. That is, assuming that the width of the convex streak portion is W _a and the width of the concave streak portion is W _b and W _a / W _b is the duty ratio, the duty ratio W _a / W does not depend on the height H of the convex streak portion. It can be configured such that the duty ratio W _a / W _b decreases as W _b is the same or as the height H of the convex linear portion increases. This makes it possible to express the texture different from the conventional one. Incidentally, in the cosmetic materials disclosed in Patent Document 1 (Japanese Patent Publication No. 7-22989) and Patent Document 2 (Japanese Patent Laid-Open Publication No. 4-125199), as described in the examples thereof, metal plate materials are used. It forms by the embossed plate manufactured by the corrosion through the photosensitive resist film patterned by exposure from a plate-bottom image. Therefore, due to the so-called side etching phenomenon, only the duty ratio W _a / W _b inevitably increases with the increase of the height H (for example, the claims of Japanese Patent No. 4612200 and FIG. 1). .

In addition, although the ridge line part of each area | region shown so far is the form in which the ridgeline is extended linearly, a convex filament part is not only this but other forms, such as curvilinear form and a wave form, in the direction which ridgeline extends. It is also possible to

Next, an example of a method of manufacturing the cosmetic material 10 will be described. However, the method of manufacturing the cosmetic 10 is not limited to this.
The manufacturing method described below includes the steps of preparing an original image, preparing an under-plate image, preparing a plate, and forming a pattern forming layer.

In the process of producing a document image, a pattern to be expressed on the pattern forming layer 12 is acquired and used as a document image. Since the original image is preferably digital data, if it is not digital data, it is converted to digital data by using a photo, a scanner or the like. Also, if the design is designed from the beginning using digital data using CAD or the like, the digital data can be used.
Thus, an original image is obtained as digital data.

In the step of producing the underprint image, a density-line conversion program generates a line pattern as a binary image on a two-dimensional virtual plane corresponding to the gradation image of the pattern by using a density-line conversion program. Layout, and obtain an underprint image as digital data.

Here, according to the preset line conditions such as the period of the convex streaks, the line shape of all lines, the direction in which the lines extend, and the variable range of the width of all lines, all lines are displayed as binary images Generate The line segments of the lines generated in this manner correspond to convex streaks in the cosmetic material, and the portions between the line segments and the straight lines correspond to concave streaks in the cosmetic material. In this way, an underprint image having a line pattern is obtained.

In the process of producing the plate, an embossed plate (mould for a decorative material) having a concavo-convex pattern in a plan view shape as shown in FIG.
The concavo-convex pattern separates a plane by connecting adjacent individual regions 14 to 23, individual regions 14 to 23, individual regions 14 to individual regions 23,... It has a collection of coated individual areas.
Here, such a concavo-convex pattern, as shown in FIG. 4 corresponding to FIG. 1 (a part of which is represented by a thick line for easy viewing), consists only of the contour shape of each region and is a linear shape In the mesh-like regions 12 ′ that do not have the convex streaks and concave streaks of the above, the linear convexes in the regions 14 to 23, the regions 14 to 23,. It is considered that the filament portion 14a, the convex filament portion 15a, the convex filament portion 16a, ..., and the concave filament portion 14b, the concave filament portion 15b, the concave filament portion 16b, ... are alternately arranged. .
Specifically, the process of manufacturing the concavo-convex pattern comprises the following steps (1) to (5).

[(1) Gradation version image creation process]
The following image creation steps (1) -1 to (1) -3 are performed using the graphic design drawing software "Illustrator" manufactured by Adobe Systems, Inc. and 2540 dpi in 8-bit image gray scale (256 gray scale) in TIFF format The image data of the resolution of (net-like area, lines and composite image of both) was created.

(1) -1
First, an image of a net-like region 12 ′ corresponding to the image shown in FIG. 4 from which the line image was removed was created from the planar view image of the concavo-convex pattern of FIG.

(1) -2
Using the drawing software “Illustrator”, the linear region convex linear portion and concave linear portion (convex linear portion 14 a and the individual linear region 14,... Shapes of the concave streaks 14b, the convex streaks 15a and the concave streaks 15b, ..., the convex streaks 22a and the concave streaks 22b, and the convex streaks 23a and the concave streaks 23b) Digital gray-scale image data corresponding to a line shape) was created according to the following specifications. An example is shown in Table 1. The gray-scale image corresponds to the image density corresponding to one coordinate of the metal roll surface described later.

Here, since the density corresponds to the plate depth of the embossed plate through the laser beam engraving process, and the absolute value of the density itself has no meaning, the image density value is converted to the plate depth (plate depth) in the above table. Is displayed. Moreover, the azimuth which is the extension direction of a concave filament part and a convex filament part is the value measured leftward from the x-axis of FIG.1 and FIG.2.

(1) -3
Using the drawing software “Illustrator”, the line shape for each individual area obtained above is embedded in each individual area in the net-like area obtained above, and gray-scale image data corresponding to the concavo-convex pattern of FIG. 1 I got This gradation image data is also referred to as unevenness image data.

[(2) Metal roll preparation process]
In parallel to the above step (1), a metal roll 30 for embossed plate engraving as shown in FIG. 5 was prepared. The metal roll 30 is formed by plating a copper layer on the surface of a hollow iron cylinder having a rotation drive shaft (shaft) 31 at both axial ends. The surface of the metal roll 30 was polished and roughened with a grindstone, and processing was performed to prevent a decrease in engraving efficiency due to specular reflection of the engraving laser light.

[(3) Laser light engraving process]
As schematically shown in FIG. 5, the surface of the metal roll 30 prepared in step (2) is engraved based on the concavo-convex pattern image data prepared in step (1) using a laser beam direct engraving machine. In this way, the uneven shape of the cosmetic material surface as shown in FIG. 1 is formed in the same plan view shape and the reverse asperity (the part corresponding to the convexity of the cosmetic material becomes concave on the embossed plate surface) on the surface. .
Therefore, the shape which the uneven | corrugated pattern in an embossing plate should have is the aspect which the uneven | corrugated relationship of the uneven | corrugated pattern in the above-mentioned decorative material reversed, and can consider it similarly considering the reversed form.

The metal roll 30 is driven via its rotary drive shaft 31 and rotates around the rotary drive shaft 31. The entire surface of the metal roll 30 is scanned with fiber laser light L having an oscillation wavelength of 1024 nm, a laser spot diameter of 10 μm, and an output of 600 W emitted from the laser head 32. At that time, the laser light is switched ON / OFF (switched between irradiation and non-irradiation) according to the density value of the concavo-convex pattern image data created in step (1), and the metal is evaporated by the laser light at the irradiation position. A recess of 10 μm in depth is formed. The scanning of the metal roll surface by the laser light was repeated 10 times. Further, in order to prevent the evaporated metal from becoming powder and remaining or adhering to the surface of the metal roll 30, the engraving liquid T was sprayed from the engraving liquid discharge head 33 onto the laser light irradiated area of the surface of the metal roll 30. Laser light was irradiated in the state.
At that time, for example, at position coordinates of the image density corresponding to the plate depth of 50 μm on the concavo-convex pattern image data, the laser light is irradiated (ON) only for the first five times out of a total of 10 scans. The laser beam is controlled to be non-irradiated (OFF) for batch.
The scanning of the laser light was completed, and the desired asperity shape was formed on the surface of the metal roll 30.

[(4) electric field polishing process]
After cleaning the engraving solution, electrolytic polishing was performed to remove metal residue attached to the surface of the metal roll 30.

[(5) Chrome plating process]
After step (4), a 10 μm thick chromium layer was formed on the surface of the metal roll by plating.

Thus, it is possible to obtain a plate (a mold for a decorative material, in this embodiment, an embossed plate) having on the surface thereof a concavo-convex shape formed by reversing the concavities and convexities of the concavo-convex pattern formed on the surface of the pattern forming layer 12.

Next, in the step of forming the pattern forming layer, the embossed material is obtained by embossing the substrate 11 using the produced plate (embossed plate). Embossing may be performed by any appropriate known method, and is not particularly limited. For example, a typical method of embossing is as follows.
A resin sheet made of a thermoplastic resin such as a polyolefin resin is used as a substrate. This base material is heated and softened, and the embossed plate is pressed against the surface thereof to form an irregular pattern of the embossed plate surface on the surface of the resin sheet. Then, the resin sheet is cooled and solidified to fix the uneven pattern on the resin sheet. Thereafter, the resin sheet on which the concavo-convex pattern is shaped is released from the embossed plate.
Here, various embossing methods are described further, for example, the following methods (A) to (E).

(A) A resin sheet to be a base material is heated and softened, and an embossed plate is pressed to perform embossing.
(B) Embossing and lamination by thermally fusing a resin sheet (base material) to be a surface sheet by heat pressure when pressing an embossing plate and a resin sheet (second base material) to be a base sheet At the same time, embossing is performed by the double embossing method.
(C) The resin sheet (base material) used as a surface sheet is melt-extruded from a T-die, brought into contact with a cylindrical embossing plate which also serves as a cooling roller, and embossed simultaneously with the film formation of the surface sheet. At this time, the resin sheet (second base material) serving as a base sheet inserted into the back side of the top sheet is heat-sealed to perform doubled embossing simultaneously with film formation.
(D) As disclosed in JP-A-57-87318, JP-A-7-32476, etc., an unhardened liquid of ionizing radiation curable resin is coated on the surface of a cylindrical embossed plate. Furthermore, in a state where a base sheet made of a resin sheet or the like is superposed thereon, ionizing radiation is irradiated to cure the uncured liquid material to form a cured product. At this time, after bonding to the base sheet, the base is released from the embossing plate and made into a base material comprising the base sheet and the cured product on the base sheet, whereby the base material is embossed.
(E) An impregnated paper obtained by impregnating a paper such as titanium paper with an uncured material of a thermosetting resin such as melamine resin is placed on core paper and wood plywood, and heat is applied from these substrates by heat pressing. A curable resin cosmetic material is produced. At that time, by inserting an embossing plate on the surface side of the impregnated paper, when the thermosetting resin is impregnated and cured to make a cosmetic material, the surface is embossed simultaneously with the heat pressing.

In addition, as a material of a base material used by the embossing method of (A)-(C), a thermoplastic resin is typically used, and as a material of a base material used by the embossing method of (D), it is represented typically Ionizing radiation curable resin is used, and thermosetting resin is typically used as the material of the substrate used in the embossing method of (E).

The cosmetic 10 can be obtained as described above.

Next, a cosmetic material as a modification of the cosmetic material 10 described above will be described. The layer configuration is shown in FIGS. 6 (a) to 6 (c). Here, in FIG. 6A to FIG. 6C, the region 14 appears as a part of the pattern forming layer 12, but the form of the pattern forming layer 12 is as described above.

Cosmetics material 10 'of a structure of Fig.6 (a) is a cosmetic material which consists of a single | mono layer. Such a cosmetic material 10 ′ may be embossed, for example, by heating and softening the base material 11 made of a thermoplastic resin sheet and pressing an embossed plate. As a result, on the surface of the base material 11, a concavo-convex pattern is formed by the pattern forming layer 12 composed of the convex streak part 14a and the concave streak part 14b having a desired concavo-convex shape. In this configuration, there is no additional decorative layer, but even when the substrate 11 is transparent, by laminating it on another material, it is possible to make a surface makeup utilizing the pattern of the other material. In addition, the substrate 11 may be colored appropriately with a coloring agent such as brown or gray, and in this case, the substrate itself is a decorative layer.

Cosmetics material 10 '' of a structure of FIG.6 (b) is the structure which formed the decoration layer 11a in the back side of the base material 11 with respect to the structure of Fig.6 (a). In order to produce the decorative material 10 ′ ′ having such a configuration, for example, a transparent resin sheet is used as the base 11 so that the decorative layer 11 a can be seen through, and the back side of the base 11 is decorated After the layer 11a is formed by printing, the layer may be heated and softened to perform embossing for pressing the surface on which the embossed plate is the front side.

With respect to the decorative material 10 ′ ′ ′ of the configuration of FIG. 6 (c), the surface of the decorative layer 11a is further on the side opposite to the side on which the pattern forming layer 12 is disposed. It is the example which laminated | stacked the other base material 11b used as a base sheet. In order to produce the decorative material 10 ′ ′ ′ having such a configuration, the decorative layer 11a is printed on the front surface of the base material 11b made of a colored opaque thermoplastic resin sheet as a base sheet. It is sufficient to laminate this base sheet and the base material 11 made of a transparent thermoplastic resin sheet as a surface sheet by heat fusion using a doubling embossing method and simultaneously emboss a desired uneven pattern on the surface of the base material 11 .

The application of the decorative material described above is not particularly limited, but, for example, interior materials of buildings such as walls, floors, and ceilings, outer walls of buildings, roofs, gates, fences and other outer coverings, window frames, Surface materials of doors, door frames and other fixtures, edges of baseboards, handrails, etc., surfaces of housings of home electric appliances such as TV sets, surfaces of furniture such as rattan, containers of boxes For example, it is a surface material, an interior material such as a vehicle or a sheath material, a ship interior material or a sheath material, or the like.

FIG. 7: is the figure (plan view) which expanded a part of decorative material 110 concerning 2nd form, and was planarly viewed from the pattern formation layer 112 side. Further, FIG. 8 shows the cross-sectional shape of the cosmetic material 110. This cross section is a thickness direction (z direction) cross section orthogonal to the direction in which the ridges of the convex linear portion 113 extend.
As can be seen from FIGS. 7 and 8, the cosmetic material 110 is configured to have a base material 111 and a pattern forming layer 112 laminated on one surface of the base material 111.

The base material 111 is a sheet-like member having a function of supporting the pattern forming layer 112 and imparting strength to the decorative material 110. Further substrate 111 in this embodiment is a substrate uneven surface S _k having an uneven surface on which is disposed forming a pattern layer 112 is formed. In this embodiment Thus irregularities in a surface of the virtual pattern top envelope surface S _t in the pattern formation layer 112 is formed.
The dotted line in FIG. 8 means that it is a virtual line.

The uneven substrate surface S _k is not uniform in surface height at the xy direction position, and is a uneven surface on which the height position of the surface changes depending on the xy direction position. More specifically, it is preferable that one or more maximal portions, that is, maximal points or maximal lines (edges or ridges) be provided, and the distance between the maximal portions be visually or tactilely recognizable. For example, the interval is preferably distributed in a range of about 3 mm to 300 mm, and more preferably about 10 mm to 100 mm.
The height change may be in one direction only, for example, the x direction only, and the y direction may be a so-called corrugated surface having a constant height. Specifically, the shape taken along the parallel imaginary cutting plane substrate uneven surface S _k in zx plane,
z = Asin (kx + φ)
y = B
(A, k, B and φ are appropriate constants)
Becomes a sinusoidal curve represented by, while the shape cut by a virtual cutting plane parallel to the yz plane is
Z = C
x = D
(C and D are appropriate constants)
The uneven | corrugated shape which is is mentioned.

Further, it may be an uneven surface whose height changes in both the x direction and the y direction. Specifically, the shape taken along the parallel imaginary cutting plane substrate uneven surface S _k in zx plane,
z = Asin (kx + φ)
y = B
(A, k, φ, B are appropriate constants)
Becomes a sinusoidal curve represented by, while the shape cut by a virtual cutting plane parallel to the yz plane is
z = Esin (my + ξ)
x = F
(E, m, ξ, F are appropriate constants)
The uneven | corrugated shape which is is mentioned.

The uneven such substrates uneven surface S _k, also other more, depending on surface appearance design or feel of decorative material to obtain, may employ various uneven surface shape.
Further, the height difference between the height of the substrate uneven surface S _k is preferably enough to be recognized in visible or tactile visually. Specifically, it is preferably about 0.1 mm or more and 10 mm or less, and more preferably about 0.5 mm or more and 1 mm or less. In particular, in the case of mass production using a manufacturing method in which a sheet-like substrate is embossed with an embossing plate in the form of a metal roll to shape irregularities, the height of the uneven substrate surface _Sk is high or low for processing suitability. The upper limit of the difference is 1 mm or less, preferably 0.7 mm or less.

The material which comprises the base material 111 can be considered similarly to the base material 11 of the above-mentioned cosmetic material 10.

The thickness of the substrate 111 is not particularly limited, but in the case of a sheet-like substrate or a film-like substrate, for example, the thickness is about 20 μm or more and about 1000 μm or less at the thinnest portion, and in the case of a plate-like substrate, for example The thinnest portion can be about 1 mm or more and 20 mm or less.

Pattern forming layer 112 is a layer laminated on the substrate uneven surface S _k of the surfaces of the substrate 111, a layer to form a pattern in the decorative material 110. In the present embodiment, the pattern forming layer 112 has the following configuration.

In this embodiment, as shown in FIGS. 7 and 8, the pattern forming layer 112 forms a pattern by alternately arranging the convex streaks 113 and the concave streaks 114.
In the cross section shown in FIG. 2, the convex streaks 113 have a substantially rectangular shape with a height H ₁₁₃ and a width W ₁₁₃ . The convex linear portion 113 has this cross section, and the ridge lines thereof are configured to extend in a direction different from the arrangement direction (for example, a direction orthogonal to the arrangement direction). The length in which the convex linear portion 113 extends is not particularly limited, and can be determined as needed. Here, the height of one convex streak 113 may be different in the width direction, but in this case, the highest portion is taken as the height of the convex streak 113. Further, for the width of the convex streak 113, the width at the center in the height direction is taken as the width of the convex streak.
On the other hand, the concave streaks 114 are formed between the adjacent convex streaks 113 as shown in FIG. 8, and the shape thereof is determined by the shape of the convex streaks 113. Therefore, the width W ₁₁₄ of the concave linear portion ₁₁₄ is a value obtained by subtracting the width W ₁₁₃ of the convex linear portion 113 from the pitch P ₁₁₃ of the convex linear portion 113.

Here, the size of W ₁₁₃ , W ₁₁₄ and H ₁₁₄ is not particularly limited, but it is preferable to be fine from the viewpoint of forming the pattern of the cosmetic material, and in the present embodiment, 1 μm ≦ W in each case. It is preferable that ₁₁₃ ≦ 1000 μm, 1 μm ≦ W ₁₁₄ ≦ 1000 μm, and 3 μm ≦ H ₁₁₃ ≦ 3000 μm.

Moreover, it is preferable that H ₁₁₃ / W ₁₁₃ (also referred to as an aspect ratio) which is the ratio of height and width in the convex streak 113 is larger than one. According to this, the texture of the cosmetic material can be made more new. However, when the aspect ratio is too large, the degree of difficulty in mold production increases, and stress on the convex filament portion 113 is concentrated and easily damaged when an external force is applied to the mold and the cosmetic material. Therefore, the aspect ratio is usually 5 or less, preferably 3 or less.

In addition, although the cross-sectional shape of the convex linear part 113 of this form is a substantially rectangle, it may be another form, without being limited to this. This includes, for example, a trapezoidal shape, a shape having a semicircular tip, and a shape with an R formed at the protruding corner portion, which can be appropriately changed. At this time, as described above, the width at the center in the height direction of the convex linear portion is the width of the convex linear portion.

Here, the pattern forming layer 112 has irregularities as a whole on the side (top side) opposite to the substrate side (base end side). The said unevenness | corrugation of this form is as follows.
As shown by the dotted line expressed by the symbol S _t in FIG. 8, the imaginary envelope surface that includes a ridge line of the top of the convex linear portions 113 and pattern the top envelope surface S _t. And in this form, this virtual pattern top envelope surface _St is formed so that it may have unevenness. The unevenness is selected from the same uneven shape as the uneven shape exemplified in the description of the base uneven surface _Sk described above.
In particular, since the top envelope surface S _t of the design has the shape of the outermost surface of the cosmetic material, it greatly contributes to the appearance design or touch feeling of the cosmetic material over the irregular surface S _{k of the} base material. Thus, in particular the pattern top envelope surface S _t is necessary to select the optimum shape for reproducing the desired appearance design to touch. For example, the surface of the decorative material reproduces the appearance design and feel of the wood surface (wood grain), and the appearance design and touch of the so-called "floating tone" wood board surface (wood grain) in which the autumn wood part protrudes on the relief. If the shape of the top envelope surface S _t corresponds to the unevenness of the annual rings on the surface of the floating wood board, the fall wood part is relatively projected and the spring wood part is relatively recessed. . In this case, the line-shaped uneven shape in which the plurality of convex streaks and the plurality of concave streaks are alternately arranged extends in a direction substantially coincident with the average traveling direction of the autumn material of the annual ring Arranged as.

For example, when the decorative material surface to reproduce the appearance design and feel of granite plates, the shape of the pattern top envelope surface S _t corresponded to the surface irregularities of the fine single crystal group arranged in the cleavage plane of the granite plate surface It is set as the uneven | corrugated shape corresponding to each single-crystal part. In this case, the line-shaped concavo-convex shape in which the convex streaks and the plurality of concave streaks are alternately arranged is a straight line for each closed region divided by the outline of each single crystal on the cleavage plane. Among the closed regions which engage in the concavo-convex shape and are adjacent via the boundary line, the extending direction of the convex streak portion and the concave streak portion, the width of the convex streak portion, and the width of the concave streak portion Any one or more may be arranged to be different.

Note that, as a specific example of the arrangement of the linear linear irregularities, the arrangement disclosed in JP-A-8-52849 (in particular, FIG. 2, FIG. 3 and FIG. 10) can be mentioned.

In this embodiment, the height of the plurality of convex linear portions 113 of the pattern formation layer 112 is the same either, irregularities of the pattern top envelope surface S _t is the substrate uneven surface S _k of the substrate 111 It will be along the unevenness. However without having to be limited to this, and may independently be formed uneven pattern top envelope surface S _t is the unevenness of the substrate as described below, the synthesis of the irregularities and other irregularities of the substrate The unevenness of the top envelope surface S _t of the pattern may be determined by this. That is, the shape of the top envelope surface S _t of the pattern and the shape of the irregular surface S _k of the substrate do not have to have the same shape, and both may have the same shape according to the desired appearance design or touch. May be another shape.

As described above, by having the convex striated portion and the unevenness at the top surface enveloping surface of the convex striated portion, it is possible to give a distinctive texture different from the conventional one in the appearance design or touch feeling.

The material for forming the pattern forming layer 112 can be considered in the same manner as the pattern forming layer 12 of the decorative material 10.

In addition, although the ridge line part 113 shown here is the form in which the ridgeline extends linearly, the present invention is not limited to this. In plan view, the ridge line part has a parabola, hyperbola, and sine with respect to the direction in which the ridgeline extends. Other forms such as curvilinear shapes such as wave curves, hyperbolic sine curves, elliptic function curves, cycloid curves and the like can also be used. The same applies to each form described later.

As described above, due to the unique structure of the form of the convex streaks, the concave streaks, and the pattern top envelope, the degree of gloss changes depending on the combination of the incident angle of the illumination light and the gaze direction of the observer. The cosmetic material has a more varied texture than ever before. Furthermore, when the design portion of the surface of the cosmetic material is touched with the hand, the feel of the feel compared to the conventional cosmetic material consisting of the convex ridge portion due to the form of the convex streak portion, concave streak portion, and design top envelope surface. Also has a more varied texture.

FIG. 9 shows a diagram for explaining the third embodiment. FIG. 9 is a cross-sectional view of the cosmetic 120 from the same viewpoint as FIG. As can be seen from FIG. 9, in the cosmetic material 120, the base material 121 on the side on which the pattern forming layer 122 is disposed is also a smooth flat surface and has no unevenness. The material and thickness of the substrate 121 can be considered in the same manner as the substrate 11.

On the other hand, in the convex streaks 123 and the concave streaks 124 included in the pattern forming layer 122, the height H ₁₂₃ of the convex streaks 123 is formed to be different among the plurality of convex streaks 123. . Thus, even substrates uneven surface S _k is a flat plane, the pattern top envelope surface S _t is configured to have irregularities.
Such a cosmetic material 120 can also provide a unique texture different from the conventional one.

Concept of irregular shape pattern top envelope surface S _t are the same as the pattern top envelope surface S _t as described in the decorative material 110.

The width _{W 123} of the convex linear portions 123, the width _{W 124} of凹線ridges 124, and the height size of the _{H 123} of the convex linear portions 123 There is no particular limitation, the decorative material pattern It is preferable to be fine from the viewpoint of forming H. In this embodiment, it is preferable that 1 μm ≦ W ₁₂₃ ≦ 1000 μm, 1 μm ≦ W ₁₂₄ ≦ 1000 μm, and 3 μm ≦ H ₁₂₃ ≦ 3000 μm, respectively.

FIG. 10: is the figure which expanded a part of decorative material 130 concerning 4th form, and was planarly viewed from the pattern formation layer 132 side. In the decorative material 130 of this embodiment, unit areas 133 which are areas of a regular hexagon are two-dimensionally arranged in the xy direction in a two-dimensional view. In FIG. 10, one unit area 133 is bordered with a thick line for easy understanding.
The unit area of this embodiment can be considered in the same manner as the unit area 33 described in the cosmetic material 10.

FIG. 11 shows an enlarged view of one unit area 133 in FIG. As can be seen from FIG. 11, the unit area 133 is further divided into ten areas of a plurality of individual areas 134 to individual areas 143, and the pattern forming layers are provided in the individual areas 134 to 143, respectively.
The individual regions of this embodiment can be considered in the same manner as the individual regions 14 to the individual regions 23 of the cosmetic material 10 described above.

12 (a) to 12 (c) show the cross-sectional shapes of the three individual areas 134, the individual areas 135, and the individual areas 136 among the individual areas 134 to the individual areas 143. This cross section is a thickness direction (z direction) cross section perpendicular to the direction in which the ridges of the convex linear portions formed in the individual regions extend.
As can be seen from FIGS. 12 (a) to 12 (c), the decorative material 130 is configured to have a base 11 and a pattern forming layer 132 laminated on one surface of the base 11. The pattern forming layer 132 forms the shapes of the unit area 133 and the individual area 134 to the individual area 143.

The base 11 of the present embodiment is the same as the base 11 of the cosmetic 10 described above. Therefore, the surface of the base 11 on which the pattern forming layer 132 is laminated is also formed to be a smooth flat surface.

The pattern forming layer 132 is a layer which forms a pattern laminated on one surface of the base material 11, and this pattern has a predetermined shape like the unit area 133 and the individual area 134 to the individual area 143. Are configured. In the present embodiment, the pattern forming layer 132 has the following configuration.

As described above, in the present embodiment, the pattern formation layer 132 has unit areas 133 of a regular hexagon in a plan view of the decorative material 130, and a plurality of unit areas 133 are two-dimensionally arranged in the xy plane to be the plane. Is covered. Each unit area 133 is divided into a plurality of individual areas 134 to individual areas 143, and a pattern is formed for each individual area. The individual area 134, the individual area 135, and the individual area 136 will be described below as an example.

As can be seen from FIG. 11 and FIG. 12 (a), the individual regions 134 are formed by alternately arranging convex linear streaks 134a and concave linear streaks 134b.
In the cross section shown in FIG. 12A, the convex streak portion 134a has a substantially rectangular shape with a height H _134a and a width W _134a . The convex streak portion 134a has this cross section, and is configured such that ridge lines extend in a direction different from the arrangement direction (for example, a direction orthogonal to the arrangement direction). The length to which the convex linear portion 134 a extends is determined by the contour shape of the individual region 134.
On the other hand, the concave streaks 134b are formed between the adjacent convex streaks 134a as shown in FIG. 12A, and the shape thereof is determined by the shape of the convex streaks 134a. Accordingly, the width W _{134 b} of the concave streak portion 134 _b is a value obtained by subtracting the width W _{134 a} of the convex streak portion 134 a from the pitch P _{134 a} of the convex streak portion 134 a.

Here, the size of W _134a , W _134b , and H _134a is not particularly limited, but it is preferable to be fine from the viewpoint of forming the pattern of the cosmetic material, and in the present embodiment, 1 μm ≦ W in each embodiment. It is preferable that _134a ≦ 1000 μm, 1 μm ≦ W _{134 b} ≦ 1000 μm, and 3 μm ≦ H _{134 a} ≦ 3000 μm.

Moreover, it is preferable that H _134a / W _134a (it is also called an aspect ratio) which is ratio of the height and width in the convex filament part 134a is larger than one. According to this, the texture of the cosmetic material can be made more new. However, when the aspect ratio is too large, the degree of difficulty in mold production increases, and stress on the convex filament portion 134a is concentrated and easily damaged when external force is applied to the mold and the cosmetic material. Therefore, the aspect ratio is usually 5 or less, preferably 3 or less.

Here, the plurality of convex streaks 134a belonging to the individual region 134 have irregularities as a whole on the side (top side) opposite to the base side (base side). The unevenness of this embodiment can also be considered similar to the pattern top envelope surface S _t as described above. That is, also in this embodiment the pattern top envelope surface S _t is formed so as to have irregularities. The irregularities may be a said pattern the top envelope surface S _t like shape.

The material forming the pattern forming layer 132 can be considered in the same manner as the pattern forming layer 112 described above.

The individual area 135 is an individual area adjacent to the individual area 134, and as can be seen from FIGS. 11 and 12 (b), convex linear streaks 135a and concave linear streaks 135b are alternately arranged. Become.
The convex streak portion 135a is a rectangle having a height H _135a and a width W _{135a in} the cross section shown in FIG. 12 (b). The convex linear portion 135a has this cross section, and the ridge line is in a direction different from the arrangement direction (for example, a direction orthogonal to the arrangement direction) and a direction different from the extending direction of the convex linear portion 134a of the individual region 134 It is configured to extend to The length to which the convex linear portion 135 a extends is determined by the contour shape of the individual area 135.
On the other hand, the concave streaks 135b are formed between the adjacent convex streaks 135a as shown in FIG. 12B, and the shape thereof is determined by the shape of the convex streaks 135a. Therefore, the width W 135 _b of the concave streak portion 135 _b is a value obtained by subtracting the width W _{135 a} of the convex streak portion 135 a from the pitch P _{135 a} of the convex streak portion 135 a.

Here, preferable ranges of the height H _135a , the width W _135a , and the width W _{135b in} the individual area 135 can be considered in the same manner as the individual area 134. In addition to this, in the individual area 135, H _134a > H _{135a in} relation to the individual area 134. Furthermore, the individual area 135 in the present _{embodiment, W 134a = W 135a, W} 134b <W 135b, _and, there is a P 134 _{<P 135.}
Here, H _{134 a} > H ₁₃₅ a means that the average of the heights of the convex streaks 134 a belonging to the individual area 134 is larger than the average of the heights of the convex streaks 135 a belonging to the individual area 135. .

Also in this case, the plurality of convex streaks 135a belonging to the individual region 135 have unevenness as a whole on the side (top side) opposite to the base side (base side). This also can be considered similar to the pattern top envelope surface S _t as described above.

The individual area 136 is an individual area adjacent to the individual area 134, and as can be seen from FIGS. 11 and 12 (c), convex linear streaks 136a and concave linear streaks 136b are alternately arranged. Become.
The convex linear portion 136a is a rectangle having a height H _136a and a width W _{136a in} the cross section shown in FIG. 12 (c). The convex linear portion 136a has this cross section, and the ridge line thereof is in a direction different from the arranging direction (for example, a direction orthogonal to the arranging direction) and a direction different from the extending direction of the convex linear portion 136a of the individual region 136 It is configured to extend to The length to which the convex linear portion 136 a extends is determined by the contour shape of the individual area 136.
On the other hand, the concave streaks 136b are formed between the adjacent convex streaks 136a as shown in FIG. 12C, and the shape thereof is determined by the shape of the convex streaks 136a. Therefore, the width W ₁₃₆ b of the concave linear portion 136 _b is a value obtained by subtracting the width W _{136 a} of the convex linear portion 136 a from the pitch P _{136 a} of the convex linear portion 136 a.

Here, preferable ranges of the height H _136a , the width W _136a , and the width W _136b in the individual area 136 can be considered similarly to the individual area 134. In addition to this, in the individual area 136, H _134a > H _{136a in} relation to the individual area 134. Furthermore, the individual area 136 in the present _{embodiment, W 134a <W 136a, W} 134b <W 136b, _and, there is a _P 135a ₌ P _136a.
Here, the H _{134a> H 136a,} the average height of the convex linear portions 134a belonging to the individual area 134, means that greater than the average height of the convex linear portions 136a belonging to the individual area 136 .

Also in this case, the plurality of convex streaks 136a belonging to the individual region 136 have unevenness as a whole on the side (top side) opposite to the base side (base side). This also can be considered similar to the pattern top envelope surface S _t as described above.

The same can be applied to the other individual areas 137 to the individual areas 143.
And, each individual area has a unique uneven shape of the top envelope surface S _t of the pattern, and at least one of the height, width, and extending direction of the ridges differs from the next individual area Is preferred.
Such a pattern forming layer 132 can also express unique texture different from before.

Among these, in the present embodiment, the average heights of the convex streaks are different between a plurality of areas (areas as a generic term of the areas present in the uneven layer regardless of the unit area and the individual areas). It is preferred that the region be included. By including a plurality of regions having different average heights in this manner, it is possible to enhance the variety of expression of texture different from the conventional one.
Here, the duty ratio can also be considered in the same manner as the cosmetic material 10.
