Description

  The present invention relates to a pearl pattern decorative body used for decoration of vending machines, refrigerators, coolers, equipment, devices, furniture, indoors, and the like, for example.

  Conventionally, as the above-mentioned pearl pattern decorative body, for example, a layer made of a pair of plastic materials on which convex wrinkles (lenses) are formed is bonded, and light entering from the surface is reflected by a metal coating formed on the back surface of the sheet. There is a synthetic plastic sheet material that produces the optical effect of US Pat. In addition, a synthetic resin base material, a base printing layer, a polarizing pearl layer, and a transparent clear layer are laminated to form a red metallic luster, blue metallic luster, and green metallic luster contained in the polarizing pearl layer. There is a decorative film having a metallic appearance of Patent Document 2 that reproduces glitter, polarization effect, and deep hue by pearl particles.

  However, the synthetic plastic sheet material of Patent Document 1 directly couples a pair of plastic materials made of the same material, but when directly joining plastic materials of different materials, the bonding surfaces of the respective materials are brought into close contact with no gap. When it is difficult to use and is used in a place that requires weather resistance, a gap is formed on the bonding surface of each material, or each material is easily peeled off in a short period of time. In addition, even when plastic materials and metal coatings of different materials are joined, the joint surfaces are easy to peel off because of the different expansion rates.

Moreover, although the decorative film of patent document 2 has printed the base printing layer, the polarizing pearl layer, and the transparent clear layer directly on the film-form base material, when the material of each layer differs, printing of each layer is carried out. When it is difficult to adhere the surface without gaps and it is used in places that require weather resistance, there may be gaps in the printed surface of the substrate, the base print layer, the polarizing pearl layer, and the transparent clear layer. One layer or each of a plurality of layers is easily peeled off in a short period of time. In addition, the metal appearance by the polarizing pearl layer only appears in a plane, and a three-dimensional appearance effect that changes the metal appearance depending on the viewing direction and angle cannot be obtained.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a pearl pattern decorative body that can clearly and clearly reveal a pearly luster / pattern.

In the pearl pattern decorative body according to the first aspect of the present invention, an anchor coat layer is formed on the back surface of a transparent decorative body, and a dot-like convex lens having a substantially hemispherical cross section is formed on the anchor coat layer. A pearl layer is formed by printing on a predetermined pattern and using an ink that reveals a pearly luster / pattern on the convex lens.

According to the present invention, light entering from the front surface side of the decorative body is refracted at an angle different from the incident angle by each convex lens formed on the anchor coat layer on the back surface of the decorative body, and each convex lens formed on the anchor coat layer (and The pearl layer on the anchor coat layer between the convex lenses is changed into various colors. In addition, pearly luster and patterns that change to various colors are radiated toward the surface of the decorative body by refracting light that has been changed to various colors in the same direction and different from the incident direction by each convex lens. Appears on the surface side.

  The decorative body can be made of a light-transmitting material such as synthetic resin or glass, for example, in such a thickness that a pearl-like luster / pattern appears. May be made of a material that is translucent or colored in a desired color. In addition, as the synthetic resin, for example, a single or composite material such as acrylic, polyethylene, polypropylene, polyester, nylon, vinyl chloride, or the like can be used.

  And when using for the place which requires a weather resistance and intensity | strength, if it comprises with an acrylic plate, it can be used as interior / exterior panels, such as a vending machine, a refrigerator, a cooler, furniture, etc., for example. Moreover, when using in the location which does not require a weather resistance and intensity | strength, you may comprise by the synthetic resin sheet | seat which has a softness | flexibility.

  The anchor coat layer can be made of, for example, a synthetic resin having an adhesive force necessary for fixing a decorative body such as a urethane-based resin or a vinyl chloride-based resin and the convex lens in a close contact state.

  The convex lens can be printed in small dots by a printing method such as screen printing, silk printing, and gravure printing using, for example, an ink (UV ink) made of an ultraviolet curable resin having translucency. Further, as the ink, it is preferable to use an ink having a viscosity and a surface tension necessary for maintaining a convex lens form during printing. In addition, a sheet, a film, or the like on which a convex lens is printed or formed may be integrally attached to the back surface of the decorative body.

  Further, for example, a convex lens having a desired refractive index such as a substantially hemispherical cross section or a substantially elliptical cross section can be formed of a synthetic resin or ink having translucency substantially the same as or substantially equivalent to the decorative body. However, if it is possible to display a pearly luster / pattern, it may be composed of a semitransparent and colored synthetic resin or ink.

  The pearl layer is an ink having a desired color that includes fine pearl particles that reflect light transmitted through the decorative body, the anchor coat layer, and the convex lens or change into various colors depending on the reflection angle of the light. Can be configured.

  The pearl pattern decorative body of the invention described in claim 2 is combined with the structure described in claim 1, and has a color that prevents the pearl layer from being seen through the pearl layer. A translucent layer is formed.

  According to the present invention, the light entering from the front side of the decorative body and the light from the back side are shielded by the opaque layer, so that the pearl layer is not seen through from the front and back, and the pearly luster / pattern Clearly appears. The light-impermeable layer can be composed of, for example, a white pressing layer made of white ink having a light shielding property to prevent the pearl layer from being seen through from the front and back. Further, if it is possible to prevent the pearl layer from being seen through, the opaque layer may be formed using an ink having a desired color other than white.

  In the pearl pattern decorative body of the invention described in claim 3, in addition to the configuration of claim 2, a mirror surface that reflects light entering from the surface side of the decorative body is formed on the opaque layer. It is characterized by that.

  According to this invention, the light transmitted through the decorative body, the anchor coat layer, the convex lens, and the pearl layer is reflected toward the surface side by the mirror surface of the light-impermeable layer, and the pearly luster / pattern is brightly shined. The light-impermeable layer can be composed of, for example, a white pressing layer made of ink having a specularity that reflects light entering from the surface side of the decorative body.

  The pearl pattern decorative body of the invention described in claim 4 is combined with the configuration described in claim 1 above, and the convex lens is stepwise or gradually from the dense region set on the back surface of the decorative body toward the rough region. They are arranged so as to be in a rough state.

  According to the present invention, the convex lenses are arranged in a stepwise or gradually coarse state (separated or dispersed) from the dense region to the coarse region, or in a stepwise or gradually dense state (from the rough region to the dense region). For example, a pearly luster / pattern that is refracted and expanded by each convex lens is gradually or gradually changed between a dense region and a rough region.

  The pearl pattern decorative body of the invention described in claim 5 is combined with the configuration described in claim 1 or 4 in a stepwise manner from the dense region set on the back surface of the decorative body toward the rough region. The arrangement is such that the intervals are gradually increased.

According to the present invention, since the interval between the convex lenses changes stepwise or gradually from the dense region to the rough region, the pearly gloss / pattern gradually or gradually changes from the dense region to the rough region. A gradation that appears
The pearl pattern decorative body of the invention described in claim 6 is stepwise from the dense region set on the back surface of the decorative body toward the rough region in combination with the configuration described in claim 1 or 4. It is characterized by being arranged so that it gradually becomes lower.

  According to the present invention, since the refractive index of each convex lens changes stepwise or gradually from the dense region to the rough region, the pearly luster / pattern gradually or gradually changes from the dense region to the rough region. The gradation which becomes becomes appears.

  According to this invention, the light that has entered from the surface of the decorative body constituting the pearl pattern decorative body is refracted by each convex lens formed on the back surface of the decorative body and irradiated to the pearl layer, and changed into various colors by the pearl layer. Since light is refracted by each convex lens again and emitted toward the surface of the decorative body, when the pearl pattern decorative body is viewed from the surface side, the pearly luster / pattern should appear in various colors. Can do.

  In addition, since the convex lens is printed on the anchor coat layer formed on the back of the decorative body having translucency, the convex lens is less likely to peel off than the convex lens is directly formed on the decorative body, and the decorative body and the convex lens are in close contact with each other. It can be firmly fixed to the state, and the weather resistance and permeability are improved.

  Further, since the opaque layer prevents the pearl layer from being seen through from the front and back, the pearly luster and pattern are clearly and clearly revealed. In addition, since the light entering from the surface of the decorative body is reflected by the opaque layer, the pearly luster / pattern can be brightly shined.

  The object of the present invention is to provide a clear and clear appearance of a pearly luster / pattern on the back of a decorative body having translucency, an anchor coat layer, a convex lens, a pearl layer, and an opaqueness. This was achieved by sequentially forming layers.

An embodiment of the present invention will be described in detail with reference to the drawings.
The drawings show a pearl pattern decorative body used for a door panel and an outlet panel constituting a vending machine. In FIGS. 3 and 4, the pearl pattern decorative body 1 is a plate having translucency. A translucent anchor coat layer 3 is formed on the back surface of the decorative body 2 with a substantially uniform thickness, and a dot-like convex lens 4 having a substantially hemispherical cross section is continuously formed on the anchor coat layer 3 in a predetermined manner. A pearl layer 5 that reveals a pearly luster and pattern is formed almost uniformly on the entire convex lens 4..., And the pearl layer 5 is seen through from the front and back. The white presser layer 6 that prevents it from being seen is formed substantially uniformly.

  The decorative body 2 is made of transparent acrylic resin having translucency, and has a size and shape corresponding to the door panel Aa and the outlet panel Ab constituting the vending machine A as shown in FIGS. It is formed to a thickness h1 at which a pearly luster / pattern of the pearl layer 5 described later appears. Moreover, although the thickness h1 of the decorative body 2 is formed to a thickness h1 of about 2.0015 mm, the thickness h1 is about 2.0015 mm or less depending on the location, purpose, use, etc. of the pearl pattern decorative body 1. You may change to h1.

  The anchor coat layer 3 is formed on the entire back surface of the decorative body 2 on which the convex lens 4 is printed using an ultraviolet curable resin ink having an adhesive force necessary to adhere and fix the decorative body 2 and the convex lens 4 in close contact with each other. (Or a part of the back surface) is formed to be substantially uniformly covered. That is, since the convex lens 4 is formed on the anchor coat layer 3, the convex lens 4 is less likely to peel than the convex lens 4 is directly formed on the decorative body 2, and the decorative body 2 and the convex lens 4 are in close contact with each other. Fixed. The anchor coat layer 3 has an average thickness h2 of about 0.002 mm, but is fixed integrally with the decorative body 2 and the convex lens 4 in close contact with each other. If the strength necessary to prevent the convex lens 4 from peeling from the back surface can be obtained, the thickness h2 may be changed to about 0.002 mm or less.

  The convex lens 4 is screen-printed using a translucent ultraviolet curable resin ink (UV ink), and is spaced at predetermined intervals with respect to the whole (or part) of the anchor coat layer 3 formed on the back surface of the decorative body 2. Are formed in a substantially hemispherical cross section when viewed from the side surface, and are formed in a substantially circular shape (or a substantially circular shape) when viewed from the back surface. Further, the height h of the convex lens 4 is formed to a height h of about 0.046 mm, the width w1 is formed to a width w1 (or diameter) of about 0.8 mm, and the interval w2 between the adjacent convex lenses 4. Are arranged at equal intervals with an interval w2 of about 0.3 mm.

  The pearl layer 5 is made of an anchor coat layer 3 using green ink containing fine pearl particles that reflect light entering from the surface of the decorative body 2 or change into various colors according to the reflection angle of the light. The outer surface of the all convex lens 4 formed above and the outer surface of the anchor coat layer 3 exposed between the convex lenses 4 are formed so as to be substantially uniformly covered. Further, the thickness h4 of the pearl layer 5 is formed to a thickness h4 of about 0.005 mm. However, if a desired pearly luster / pattern appears, the thickness h4 is about 0.005 mm or less or more. You may change to In the embodiment, the pearl layer 5 is formed with green ink. However, for example, it can be formed with ink of a desired color according to the use, preference, demand, and the like.

  The white presser layer 6 is white so as to have a non-translucency that prevents the pearl layer 5 from being seen through from the front and back sides and a specularity that reflects light entering from the surface of the decorative body 2. The entire pearl layer 5 (or part) formed on the all-convex lens 4 and the anchor coat layer 3 is formed so as to be substantially uniformly covered with ink. That is, light entering from the front surface side of the decorative body 2 is not transmitted to the back surface side, but light from the back surface side is shielded, so that a white pressing effect that prevents the pearl layer 5 from being seen through from the front and back surfaces can be obtained. In addition, a reflection effect of reflecting almost all the light transmitted through the decorative body 2, the anchor coat layer 3, the convex lens 4, and the pearl layer 5 toward the surface side of the decorative body 2 is also obtained.

  On the other hand, when the white pressing layer 6 is not formed, the white pressing effect by the white ink cannot be obtained, and the light entering from the front surface side of the decorative body 2 passes through to the back surface side, so that the pearly luster and pattern clearly appear. Not issued. Moreover, although the thickness h5 of the white presser layer 6 is formed to a thickness h5 of about 0.005 mm, the white presser effect for preventing the pearl layer 5 from being seen through from the front and back and the light entering from the surface of the decorative body 2 The thickness h4 may be changed to about 0.005 mm or less or a thickness h4.

  Since the decorative body 2, the anchor coat layer 3, and the convex lens 4 are colorless and transparent or semi-transparent, when the green colored pearl layer 5 is formed, a pearly luster / pattern having a green color appears. Although one or more of the decorative body 2, the anchor coat layer 3, the convex lens 4, and the white presser layer 6 is used, for example, red, blue, yellow, purple, orange, other colors, etc. If a single color or a combination of a plurality of colors is used, a pearly luster / pattern can appear in a desired color or a favorite color.

  The illustrated embodiment is configured as described above, and an example in which the pearl pattern decorative body 1 is used for the door panel Aa and the outlet panel Ab of the vending machine A will be described below.

  First, as shown in FIGS. 3 and 4, light entering from the surface side of the decorative body 2 constituting the pearl pattern decorative body 1 is different from the incident angle by the respective convex lenses 4 through the anchor coat layer 3. The pearl layer 5 formed on each convex lens 4 is irradiated. Further, a part of the light transmitted between the convex lenses 4 is irradiated to the pearl layer 5 without being refracted.

  Moreover, the light refracted by each convex lens 4 and the light transmitted between the convex lenses 4 are reflected by the pearl particles contained in the pearl layer 5 and change into various colors. A pattern appears.

  In addition, some light changed to various colors is transmitted through the pearl layer 5, but transmission to the back surface side is blocked by the white pressing layer 6 formed on the pearl layer 5, and light from the back surface side is white pressed. Since the light is blocked by the opaqueness of the layer 6, a white pressing effect that prevents the pearl layer 5 from being seen through from the front and back is obtained, and the pearly luster and pattern are clearly and clearly shown.

  In addition, almost all light transmitted through the pearl layer 5 is reflected toward the surface side by the mirror surface of the white pressing layer 6 to brighten the pearly luster / pattern and to be changed into various colors by the pearl layer 5. And the light reflected toward the surface side by the white pressing layer 6 are refracted by the convex lenses 4 in a direction different from or in the same direction as the incident direction, and the surface of the decorative body 2 is passed through the anchor coat layer 3. 1 and 2, when the door panel Aa and the outlet panel Ab of the vending machine A configured by the pearl pattern decorative body 1 are viewed from the front side, as shown in FIGS. The pearly luster / pattern that appears on the surface side of the outlet panel Ab changes to various colors.

  In addition, the refraction angle of light by the convex lenses 4... And the reflection angle of light by the white pressure layer 6 differ depending on the viewing direction and angle of the door panel Aa and the outlet panel Ab. Not only will it change, but the way it shines will also change in various ways, so pearly luster and patterns will appear in three dimensions. Further, the pearly luster / pattern on which the pearl layer 5 appears due to the refractive power and the magnifying power of each convex lens 4.

  FIG. 5 shows that the interval w2 between the convex lenses 4... Is stepped from the dense region (right side in the figure) set on the back surface of the decorative body 2 toward the rough region (left side in the figure). Another example is shown in which the pattern is gradually widened, and the interval between the convex lenses 4... Gradually or gradually changes from the dense region to the coarse region, so that the pearly luster / pattern is changed from the dense region. Gradation that gradually or gradually becomes rough toward the rough area can be displayed, and operations and effects substantially equivalent to those of the above embodiment can be achieved.

  6 shows that the height h of each convex lens 4... Increases from the dense area (right side in the figure) set on the back surface of the decorative body 2 toward the rough area (left side in the figure). In other examples, the refractive index of each convex lens 4 changes gradually or gradually from a dense region to a rough region, so that the pearly luster / pattern is a dense region. Gradation that gradually or gradually becomes rough toward the rough region can appear, and the effects and effects substantially the same as those of the above embodiment can be achieved.

  Further, it is possible to obtain a decoration effect that produces a gradation in which the pearly luster / pattern gradually or gradually becomes rough from the dense region to the rough region. You can also visually enjoy fluctuations and changes just by looking at the gradation of a three-dimensional pattern. For example, if you use it for various purposes and purposes, such as advertising, guidance, and sales of products, it is easy to attract people's attention. High advertising effectiveness can be obtained.
