The present application provides a decorative member and a method of manufacturing the decorative member having dichroism showing different colors depending on the viewing direction and improving the visibility of the dichroic.

The present application relates to a decorative member. The decorative member according to the exemplary embodiment of the present specification includes a pattern layer including a convex or concave-shaped surface having a cross section of an asymmetric structure; And an inorganic layer provided on the convex or concave-shaped surface.

In this specification, the term “or” means “and / or” when it includes any or all of the listed items, unless otherwise defined.

In the present specification, the term "layer" means covering 70% or more of the area in which the layer exists. It means preferably covering at least 75%, more preferably at least 80%.

In this specification, a cross section means the surface at the time of cut | disconnecting the said convex part or recessed part in either direction. For example, the cross section may mean a surface when the convex portion or the concave portion is cut in a direction parallel to the ground or perpendicular to the ground when the decorative member is placed on the ground. The convex or concave-shaped surface of the pattern layer of the decorative member according to the embodiment is characterized in that at least one of the cross sections in the direction perpendicular to the ground has an asymmetrical structure.

In the present specification, the cross section of the asymmetric structure means that the figure composed of the edge of the cross section is a structure having no line symmetry or point symmetry. Line symmetry refers to the property of overlapping when a figure is symmetric about a straight line. Point symmetry means that when a figure is rotated 180 degrees around a point, it has a symmetrical property that completely overlaps the original figure. Here, the edge of the cross section of the asymmetric structure may be a straight line, a curve or a combination thereof.

이며, 0<ΔE^*ab<1의 범위 내에서는 관찰자가 색 차이를 인식할 수 없다[참고문헌: Machine Graphics and Vision 20(4):383-411]. 따라서, 본 명세서에서는 이색성을 ΔE^*ab>1로 정의할 수 있다. As mentioned above, the said decorative member can express dichroism by the convex part or concave part which has the cross section of the asymmetric structure contained in the surface of a pattern layer. Dichroism means that different colors are observed depending on the viewing angle. The color can be represented by CIE L * a * b *, and the color difference can be defined using a distance (ΔE ^* ab) in L * a * b * space. Specifically, the color difference is

In the range 0 <ΔE ^* ab <1, the observer cannot perceive the color difference (Ref. Machine Graphics and Vision 20 (4): 383-411). Therefore, in the present specification, dichroism may be defined as ΔE ^* ab> 1.

According to a preferred embodiment, the surface of the convex portion or the concave portion includes two or more of the convex portion or the concave portion shape. Thus, dichroism can be made larger by having two or more convex or recessed surfaces. In this case, two or more convex portions or concave portions may have the same shape, but different shapes may be included.

According to the exemplary embodiment of the present specification, the convex portion or the concave portion having the cross section of the asymmetric structure includes two or more sides having at least one cross section having different inclination angles, different degrees of bending, or different sides. For example, when two sides of at least one cross section constituting at least one cross section have different inclination angles, different degrees of bending, or different sides, the convex portions or concave portions have an asymmetrical structure.

According to a preferred embodiment of the present specification, the shape of the convex portion or the concave portion includes a first inclined side and a second inclined side of at least one cross-section is different from each other.

In the present specification, unless otherwise indicated, "side" may be a straight line, but is not limited thereto, and all or part of the curve may be curved. For example, the sides may include a portion of an arc of a circle or ellipse, a wave structure, a zigzag structure, or the like.

 In the present specification, when the variation includes a portion of an arc of a circle or an ellipse, the circle or ellipse may have a radius of curvature. The radius of curvature may be defined as the radius of the arc when the extremely short section of the curve is converted into an arc.

In the present specification, unless otherwise indicated, the term "inclined side" means the side of the angle when the decorative member is placed on the ground is more than 0 degrees and less than 90 degrees. At this time, when the side is a straight line, the angle between the straight line and the ground can be measured. When the side includes a curve, when the decorative member is placed on the ground, the angle formed by the straight line connecting the point closest to the ground and the furthest point from the ground among the sides at the shortest distance can be measured. Can be.

In this specification, unless otherwise stated, an inclination angle is an angle which the surface or side which comprises the said pattern layer with the ground when the said decoration member is placed on the ground, is more than 0 degree and 90 degrees or less. Alternatively, a line segment (a'-b ') generated when the point (a') where the face or side of the pattern layer is in contact with the ground and the point (b ') farthest from the face or side of the pattern layer are connected to each other. ) May mean an angle formed by the ground.

In this specification, unless otherwise stated, the degree of curvature refers to the degree of change in the slope of the tangent at successive points on the side or face. The greater the change in the slope of the tangent at successive points on the side or face, the greater the degree of curvature.

An angle a1 formed between the first inclined side L1 and the second inclined side L2 may be in a range of 80 degrees to 100 degrees. The angle a1 may be specifically 80 degrees or more, 83 degrees or more, 86 degrees or more, or 89 degrees or more, and 100 degrees or less, 97 degrees or less, 94 degrees or less, or 91 degrees or less. The angle may refer to the angle of the vertex consisting of the first inclined side and the second inclined side. When the first inclined side and the second inclined side do not form a vertex with each other, the first inclined side and the second inclined side may mean an angle of a vertex in a state in which a vertex is formed.

The difference between the inclination angle a2 of the first inclined side of the convex portion P1 and the inclination angle a3 of the second inclined side may be in a range of 30 degrees to 70 degrees. The difference between the inclination angle a2 of the first inclined side and the inclination angle a3 of the second inclined side may be, for example, 30 degrees or more, 35 degrees or more, 40 degrees or more, or 45 degrees or more, 70 degrees or less, 65 degrees or less. , 60 degrees or less or 55 degrees or less. When the difference between the inclination angles of the first inclination edge and the second inclination edge is within the above range, it may be advantageous in terms of implementation of color representation according to the direction.

According to one example, the shape of the convex portion or the concave portion of the surface of the pattern layer may be a convex portion of the cone shape protruding out of the surface of the pattern layer or the shape of a cone recessed into the surface of the pattern layer. It may be a recess of.

Cone forms include cones, ellipses, or polygonal cones. Here, the shape of the bottom surface of the polygonal pyramid includes a triangle, a square, and a star shape having five or more protruding points. According to an example, when the decorative member is placed on the ground, when the surface of the pattern layer has a cone-shaped convex shape, at least one of the vertical cross-sections of the convex shape with respect to the ground may be triangular in shape. . According to another example, when the decorative member is placed on the ground, when the surface of the pattern layer has a concave shape of a cone, at least one of the vertical cross-sections of the concave shape with respect to the ground is an inverted triangle shape. Can be.

According to an example, the cone-shaped convex portion or the cone-shaped concave portion may have at least one cross section of an asymmetric structure. For example, when the convex portion or the concave portion of the cone shape is observed from the surface side of the convex portion or the concave portion, when two or less identical forms exist when rotating 360 degrees from the vertex of the cone, the dichroism is It is advantageous to be expressed. Fig. 7 shows the convex shape of the cone shape observed from the surface side of the convex shape, (a) shows the cone shape of the symmetrical structure, and (b) shows the cone shape of the asymmetric structure. It is illustrated.

When the decorative member is placed on the ground, the cone shape of the symmetrical structure has a circular cross section (hereinafter referred to as a horizontal cross section) in a direction horizontal to the ground, or a regular polygon having the same length of each side, and the vertex of the cone is on the ground. It is a structure existing on a line perpendicular to the cross section of the center of gravity of the horizontal cross section for. However, a cone shape having a cross section of an asymmetric structure is located on the vertical line of the point where the vertex position of the cone is not the center of gravity of the horizontal cross section of the cone when observed from the surface side of the shape of the convex portion or the recess portion of the cone shape. Or the horizontal cross section of the cone is a polygon or ellipse of an asymmetric structure. When the horizontal cross section of the cone is a polygon of an asymmetric structure, at least one of the sides or angles of the polygon may be designed differently from the rest.

For example, as shown in Figure 8, the position of the vertex of the cone can be changed. Specifically, as shown in the first picture of Fig. 8, when the vertex of the cone is designed to be positioned on the vertical line of the center of gravity (01) of the horizontal cross section with respect to the ground of the cone when viewed from the surface side of the convex shape of the cone shape, Four identical structures can be obtained at 360 degrees of rotation from the vertex of the cone (4 fold symmetry). However, the symmetrical structure is broken by designing the vertices of the cone at position 02, not the center of gravity 01 of the horizontal cross section with respect to the ground. The length of one side of the horizontal cross section with respect to the ground x, the distance of the cone's vertices a and b, the height of the cone shape, the length of the line connected vertically from the vertex of the cone (01 or 02) to the horizontal cross section with respect to the ground. h, the angle formed between the horizontal cross section and the side surface of the cone is? n, and a cosine value can be obtained as described below with respect to planes 1, 2, 3 and 4 of FIG.

At this time, since θ1 and θ2 are the same, there is no dichroism. However, since θ3 and θ4 are different, and │θ3 to θ4│ mean a color difference E * ab between two colors, they may exhibit dichroism. Where? 3-? 4 |> 0. Thus, by using the angle between the horizontal cross section and the side surface of the cone surface, it is possible to quantitatively indicate how the symmetrical structure is broken, that is, the degree of asymmetry. Proportional.

According to another example, the pattern layer has a surface of a convex portion having a linear point or a concave portion having a linear point. 10 to 12 show photographs of an example of implementing a convex portion having a line shape. The linear shape may be a straight line, a curved line, may include both a curved line and a straight line, or may be zigzag. The center of gravity of the horizontal cross section with respect to the ground surface of the convex portion or the concave portion is observed when the surface of the convex portion having the highest point is linear or the concave portion having the lowest point is observed from the surface side of the convex portion or the concave portion. It is advantageous to express dichroism when there is only one identical form when rotated 360 degrees as a reference. Fig. 9 shows a surface having the shape of a convex portion having a peak at a line, (a) illustrates a pattern having convex portions that do not express dichroism, and (b) has convex portions expressing dichroism. The pattern is illustrated. X-X 'cross section of FIG. 9 (a) is an isosceles triangle or equilateral triangle, and Y-Y' cross section of FIG. 9 (b) is a triangle from which the side length differs.

According to another example, the pattern layer has a convex or concave-shaped surface of the structure in which the tip of the cone shape is cut off. In FIG. 13, when the decorative member is placed on the ground, a photograph embodying an inverted trapezoidal recess having an asymmetrical cross section perpendicular to the ground is shown. Such asymmetric cross sections may be trapezoidal or inverted trapezoidal in shape. Also in this case, dichroism can be expressed by the cross section of an asymmetric structure.

In addition to the structure illustrated above, various convex or concave-shaped surfaces as shown in FIG. 14 may be implemented.

According to one embodiment, the shape of the convex portion or the concave portion includes a first inclined surface and a second inclined surface different from each other.

In the present specification, unless otherwise stated, the "face" may be a plane, but is not limited thereto, and all or part of the surface may be curved. For example, the shape of the cross section in a direction perpendicular to the plane may include a portion of an arc of a circle or ellipse, a wave structure, a zigzag structure, or the like.

In the present specification, unless otherwise stated, the term "inclined surface" means a surface of which the angle formed by the surface with respect to the ground is greater than 0 degrees and less than 90 degrees when the decorative member is placed on the ground. At this time, when the plane is a plane, the angle between the plane and the ground can be measured. When the surface includes a curved surface, when the decorative member is placed on the ground, an angle formed by a straight line connecting the point closest to the ground and the farthest point among the surface with the ground is measured.

In the drawings, unless otherwise specified, the first inclined plane may be defined as a left inclined plane of the convex portion, and the second inclined plane may mean a right inclined plane of the convex portion.

The convex portion P1 of the pattern layer may have a polygonal cross section and have a pillar shape extending in one direction. In one example, the cross section of the convex portion P1 may be triangular or have a shape further including a small concave portion at the tip (a pointed portion or a vertex portion) of the triangle.

An angle a1 formed between the first inclined surface S1 and the second inclined surface S2 may be in a range of 80 degrees to 100 degrees. The angle a1 may be specifically 80 degrees or more, 83 degrees or more, 86 degrees or more, or 89 degrees or more, and 100 degrees or less, 97 degrees or less, 94 degrees or less, or 91 degrees or less. The angle may refer to the angle of the vertex consisting of the first slope and the second slope. When the first inclined surface and the second inclined surface do not form a vertex with each other, the first inclined surface and the second inclined surface may mean an angle of a vertex in a state of forming a vertex.

An interval between the convex portions P1 may be 0 μm to 20 μm. In the present specification, the distance between the convex portions may mean the shortest distance between two adjacent convex portions, at which one convex portion ends and another convex portion starts. If the spacing between the convex portions is properly maintained, the decorative member should have a relatively bright color when viewed from the side of the inclined surface where the inclination angle of the convex portion is larger, thereby improving the phenomenon that the reflection area is dark due to shading. As described later, a second convex portion having a smaller height than the convex portion may exist between the convex portions. The description relating to this spacing can be applied not only to the convex portion but also to the concave portion described above.

The pattern layer may have a flat portion on a surface opposite to the surface on which the convex portion is formed, and the flat portion may be formed on the base layer. A plastic substrate can be used as the substrate layer.

In the present application, the light absorption layer and the light reflection layer are named according to their function. For light having a specific wavelength, a layer that reflects light relatively much may be represented by a light reflection layer, and a layer that reflects light relatively little may be represented by a light absorption layer.

41, the light absorption layer and the light reflection layer will be described. In the decorative member of FIG. 41, each layer is laminated in the order of L _i-1 layer, L _i layer, and L _{i + 1} layer with respect to the direction of light input, and between the L _i-1 layer and the L _i layer. the interface (interface) i _i is located, and the interface i _{i + 1} located between the layer L _i and L _{i + 1} layer.

When irradiating light having a specific wavelength in a direction perpendicular to each layer so that thin film interference does not occur, the reflectance at the interface Ii may be expressed by Equation 1 below.

[Equation 1]

In Equation 1, n _i (λ) denotes a refractive index according to the wavelength λ of the i-th layer, and k _i (λ) denotes an extinction coefficient according to the wavelength λ of the i-th layer. Means. The extinction coefficient is a measure that can define how strongly the target material absorbs light at a particular wavelength, as defined above.

By applying Equation 1 above, when the sum of reflectances for each wavelength at the interface I _i calculated at each wavelength is R _i , R _i is represented by Equation 2 below.

[Equation 2]

In this case, when in the interface between the layered product Ii R _i is the larger, and the contact surface Ii, can be defined as the light-reflecting light-absorbing layer and the other layer in the layer opposite to a direction in which the light entering the interface between Ii. For example, in the laminate shown in Fig. 41, when the sum of the wavelength specific reflectivity of the interface I _{i + 1} the largest, in contact with I _{i + 1,} the interface I _{i + 1} and the light is located opposite to the incoming direction The layer L _{i + 1} layer may be defined as a light reflection layer, the remaining layers L _i-1 and L _i layers as light absorbing layers.

The present application also relates to a method of manufacturing a decorative member. 4 exemplarily shows a method of manufacturing a decorative member of the present specification. Exemplary manufacturing methods include preparing a pattern layer comprising a convex or concave-shaped surface having a cross-section of an asymmetric structure; And forming an inorganic layer on the surface of the convex or concave portion having the cross section of the asymmetric structure of the pattern layer.

As an example, the manufacturing method may deposit the first and second inorganic layers on the first and second inclined surfaces of the pattern layer including the convex-shaped surfaces including the first and second inclined surfaces having different inclination angles, respectively. It may include doing.

An exemplary manufacturing method deposits an inorganic layer on each of the two inclined surfaces of the pattern layer, so that the thickness and type of the inorganic layer may be adjusted on each inclined surface, thereby broadening the dichroic spectrum. Unless otherwise described with respect to the manufacturing method, the contents described in the items of the decorative member may be equally applied.

The first and second inorganic layers are respectively formed on the first and second slopes by sputtering, evaporation, evaporation, chemical vapor deposition, wet coating, and the like. Can be formed. In particular, since the sputtering method is straight, it is possible to maximize the difference in deposition thickness of both inclined surfaces by tilting the position of the target.

 In one example, the first inorganic layer 201 is tilted toward the smaller slope of the first and second slopes of the pattern layer 10 to deposit the first inorganic layer 201 (S1). 2 inorganic layer 202 may be deposited (S2). The order of the process (S1 and S2) may be reversed, it may be advantageous in terms of depositing inorganic materials of different thickness on both inclined surfaces.

The first and second inorganic layers may be deposited on the first and second inclined surfaces with different thicknesses. The thicknesses of the first and second inorganic layers may be appropriately adjusted in consideration of the desired luminous characteristics within the range described in the items of the decorative member, respectively.

The first and second inorganic layers may be deposited on the first and second inclined surfaces with different materials. The materials of the first and second inorganic layers may be appropriately adjusted in consideration of the desired visibility characteristics in the material in the items of the decorative member, respectively.

The inorganic layer may be composed of a single layer, it may be composed of a multilayer of two or more layers.

According to an exemplary embodiment, the inorganic material layer may include a third inorganic material layer and a fourth inorganic material layer sequentially stacked on the convex or concave-shaped surface. According to another exemplary embodiment, the inorganic material layer may include a fourth inorganic material layer and a third inorganic material layer sequentially stacked on the convex or concave-shaped surface. The materials included in each layer may be the same or different from each other. In addition, the material of the third and fourth inorganic material layer may include the material of the inorganic material layer described above. The third inorganic layer may be represented by a light absorption layer, and the fourth inorganic layer may be represented by a light reflection layer. For example, the inorganic layer may include a light absorption layer and a light reflection layer sequentially stacked on the convex or concave-shaped surface, or the inorganic layer may be a light reflection layer sequentially stacked on the convex or concave-shaped surface. It may include a light absorbing layer.

In the present specification, the light absorbing layer and the light reflecting layer is a layer having relative properties to each other, the light absorbing layer means a layer having a higher light absorption than the light reflecting layer, the light reflecting layer is a light reflectivity compared to the light absorbing layer It can mean a high layer.

The light absorption layer and the light reflection layer may each be composed of a single layer, or may be composed of two or more layers.

In the light absorbing layer, light is absorbed at the incident path and the reflecting path of the light, and the light is reflected at the surface of the light absorbing layer and at the interface between the light absorbing layer and the light reflecting layer, respectively, so that the two reflected light beams reinforce or cancel each other. In the present specification, the light reflected from the surface of the light absorbing layer may be represented by the surface reflected light, the light reflected from the interface between the light absorbing layer and the light reflecting layer. Figure 15 shows a schematic diagram of such a principle of action. 15 illustrates a structure in which the substrate 101, the light reflection layer 201, and the light absorption layer 301 are stacked in this order, but the substrate is located below the light reflection layer, but is not essential.

The light reflected from the surface of the light absorbing layer may be represented by the surface reflected light, and the light reflected from the interface between the light absorbing layer and the light reflecting layer may be represented as interface reflected light.

According to one embodiment of the present specification, as shown in FIG. 6, the inorganic material layer represents a decorative member having a multilayer structure. Specifically, the light absorption layer 401 and the light reflection layer 501 sequentially formed on the surface of the convex portion of the pattern layer may be included. At this time, the thickness t1 of the light reflection layer in the region E of the pattern layer including the first inclined surface and the thickness t2 of the light reflection layer in the region F of the pattern layer including the second inclined surface may be the same or different. Figure 6 relates to a light absorption layer having a structure in which the inclined surfaces facing each other, that is, the cross section is triangular. In the structure of the pattern having the inclined surfaces facing each other as shown in Figure 6, even if the deposition is carried out under the same conditions, the thickness of the light absorption layer may be different on the two surfaces of the triangular structure. Accordingly, the light absorption layer having two or more regions having different thicknesses can be formed by only one process. As a result, the expression color is different depending on the thickness of the light absorption layer. At this time, if the thickness of the light reflection layer is more than a certain amount does not affect the color change.

The light reflecting layer is not particularly limited as long as it is a material capable of reflecting light, but the light reflectance may be determined depending on the material, for example, color is easily implemented at 50% or more. Light reflectance can be measured using an ellipsometer.

The light absorption layer has an extinction coefficient k of 400 nm and greater than 0 and 4 or less, preferably 0.01 to 4, 0.01 to 3.5, 0.01 to 3, and 0.1 to 1. The extinction coefficient (k) is-(l / 4pI) (dI / dx), where the path unit length in the light absorbing layer (dx), e.g., the fraction of dI / I of light intensity per meter multiplied by l / 4p Value, where l is the wavelength of light.

The light absorption layer has an extinction coefficient k of 380 to 780 nm greater than 0 and 4 or less, preferably 0.01 to 4, 0.01 to 3.5, 0.01 to 3, and 0.1 to 1. Since the extinction coefficient k is in the above range in the entire visible light wavelength range of 400 nm, preferably 380 to 780 nm, it may serve as a light absorbing layer within the visible light range.
