Description

METHODS FOR MANUFACTURING SELF COLORED REFLECTIVE MATERIAL FOR TRANSCRIPTION}

The present invention relates to a method for producing a self-recovering retroreflective material for transfer.

In general transfer monochromatic or multicolor retroreflective materials used for advertising or as a material for clothing, product promotion, safety marking, etc., a common adhesive is coated on the top surface of a synthetic resin film (PET film, etc.). The glass beads are fixed. Next, an ink layer having any single color or multicolor is formed on the glass bead top surface, and then a thermal adhesive is formed on the ink layer. The thermal adhesive is brought into contact with the surface of the object, and then heat is applied to the upper surface of the synthetic resin film with an iron or a hot press, and a predetermined pressure is applied. When the thermal adhesive adheres to the surface of the object, the synthetic film is peeled off. Serve At this time, the pressure-sensitive adhesive is peeled off together with the synthetic resin film so that the glass beads are exposed to the outside. As a result, when light is applied to the glass beads, a retroreflective effect appears.

However, the color of the ink layer is visually observed not only when the retroreflective material is directly exposed to the light source but also when it is normally indirectly exposed to the light source. That is, when the retroreflective object is visually observed Since the applied color is exposed, the composition of the color, the type, and the design that the color is formed are exposed, so that there is a problem that the mystery, the merchandise, and the workability are slightly lowered.

Therefore, the present invention, when having a multi-color or monochromatic color structure, the original color is expressed only when it is directly exposed to the light source, and the original color is not normally expressed when the direct color is not directly exposed to the light source. It provides a method of manufacturing its own color-reconstructed reflexes, which gives the mystery, merchandise, work, etc. superiority by giving features that are not identified by color.

To this end, the present invention, the first self-recovering resin layers of the first self-recovering color through the screen method while maintaining a minute gap from each other on a known reflective sheet that glass beads are coated on the combined PET film and PE film A first process of printing; It provides a method for producing a self-color restored retroreflective comprising a second process of forming a second self-color restored reflective resin layer on the entire surface of the self-color restored reflective resin layers, and also the present invention Self-color restored retroreflective material, characterized in that to print the entire color of the self-recovering resin layer through the screen method or the rolling method on a known reflection sheet coated with glass beads on the PET film and PE film It provides a manufacturing method.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, it should be noted that only parts necessary for understanding the present invention will be described, and descriptions of other parts will be omitted so as not to obscure the subject matter of the present invention.

The present invention uses a conventional reflective sheet coated with glass beads, as described above, which is a product that is already on sale, and in the related art, a simple retroreflective and multicolored retroreflective navel, recursive Reflective sheets and the like are produced.

In the present invention, referring to FIG. 1, first screen printing of the resin layers 100, 100a, 100b, and 100c for use with the first self-color reconstruction mirror is performed on the upper surface of the glass bead 30. At this time, the predetermined intervals A, A1, and A2 are maintained between the resin layers 100, 100a, 100b, and 100c. The spacing (A, A1, A2) may be 0.1mm or less depending on the characteristics of the design and can be freely adjusted to 1mm to 2mm or 5mm, 10mm and the like. The shape of the pattern may also be selected.

Next, the second self-color restored reflective resin layer 100d is printed on the entire surface of the first self-color restored reflective resin layers 100, 100a, 100b, and 100c.

At this time, in order to print the first self-recovery resin layer (100, 100a, 100b, 100c) is used to print any pattern on the screen printing frame, the second self-recovery resin layer (100d) In order to print, printing is performed using a screen without a pattern, that is, without a pattern. Therefore, the printing of the resin layers (100, 100a, 100b, 100c, 100d) of the present invention is very simple.

In more detail, the resin layers 100, 100a, 100b, and 100c to be primarily printed are printed as they are, and the intervals A and A1 between the resin layers 100, 100a, 100b, and 100c. , A2). Next, the resin layer 100d to be printed secondly penetrates the upper surfaces of the first resin layers 100, 100a, 100b, and 100c as well as the gaps A, A1, and A2, and eventually prints to the upper surface of the glass beads. To be. Therefore, in the practice of the present invention, the problem of concealing while precisely aligning the boundary lines between the first resin layers is eliminated and complicated work is very easily performed.

Thereafter, a known hot melt resin 50 is applied to the upper surface of the second resin layer 100d, thereby completing the first embodiment of the present invention.

Next, the second embodiment of the present invention as shown in FIG. 2 is almost the same as the first embodiment, but in order to express only one type of color, only the resin layer 200 for self-color restoration semi-printing is printed on the entire surface of the glass bead.

On the other hand, the self-color restored semireflective resin which becomes the main part in this invention is demonstrated. The resin may be any one of polyurethane-based transparent resin or polystyrene resin, polyvinyl chloride, polymethyl methacrylate resin, polyethylene resin, or polypropylene resin having excellent transparency. Or 5 to 40 parts by weight of a reflector coated with a material having a high refractive index, such as iron oxide, the titanium oxide or iron oxide is coated on the entire surface of the mica plate, the coating thickness is preferably 0.1 micron to 5 microns or less. . In this case, the thinnest coating thickness is used to express a gold color system (including yellow and orange) when exposed to a light source, and the thickest coating thickness is expressed to a green color. The colors are blue, lilac, purple and purple. On the other hand, the content of the reflector is 5 to 40 parts by weight relative to the amount of resin as described above, although the content can be increased even more than that, but the unit price is increased and is not preferable in terms of physical properties, while the content below that This is because it is not highly desirable in terms of physical properties as well as the reflection effect.

Next, the method using the present invention completed as described above put the hot melt resin (50) layer on the skin complexion and at the same time put a weight to heat on the PET film (10) and the hot melt resin (50) of the skin complexion It is firmly attached to the surface. Next, when the PET film 10 is grabbed and peeled off, the PE film 10 is also detached from the glass beads at the same time, so that the glass beads are used while being exposed.

On the other hand, when the reflector of the present invention is not directly exposed to the light source but indirectly exposed in a normal state, the color of the resin layer is expressed in ivory color or off-white color, and is directly exposed to the light source. When light is shined at a right angle, each color is vividly expressed as described above. Therefore, the present invention is usually expressed in soft white, but when exposed directly to a light source, beautiful color is reflected recursively.

As described above, the present invention relates to a method capable of producing a highly detailed and complex retroreflective pattern of a pattern while allowing the color concealed inside the resin layer to be clearly displayed only when exposed to a direct light source. Reflector produced by the present invention can feel aesthetics, texture, yang that can not be felt in the conventional reflector can be widely used in various fields as well as excellent effect of merchandise, mystery, workability and the like. . As a result, new applications in the field of retroreflective materials can be explored, creating high added value.
