Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative body having an arbitrary brilliant or iridescent (hereinafter referred to as interference color) pattern formed on a metal or resin substrate. It is suitable for decoration such as watches and makeup containers.

[0002]

2. Description of the Related Art Interference colors differ from conventional colors (eg, pigments and dyes) in that colors are observed due to light interference. This interference occurs as a result of repeated reflection, refraction, and transmission when light moves between substances. Conventional decorative interference films utilizing this phenomenon can be obtained by a method of transferring a hologram foil (for hot stamping), a method of forming a resin layer using a clear paint in which a pearl pigment is dispersed, or an ion plating method. There is a method of forming a titanium oxide film.

A method of transferring a hologram foil is to transfer and form an interference color pattern to a substrate by a hot stamping method using a commercially available hologram foil. When the base material is a metal, a resin layer is formed in advance. A method for forming a transparent resin layer in which a pearl pigment is dispersed is to first form a colored layer on a base material by using a method such as painting or printing, and then form a clear coating containing the pearl pigment thereon. Alternatively, a transparent resin layer is formed by using ink, and the effect of changing the color tone by the interaction between the color tone of the base and the interference color of the pearl pigment is obtained. In the case where the base material is a colored resin, the formation of the colored layer is appropriately omitted. A method of forming a titanium oxide film by an ion plating method is to form a transparent titanium oxide thin film by using an ion plating method,
The light interfered by refraction and reflection, and an effect that looks like a rainbow was obtained.

[0004]

All of the above methods can express rainbow colors or specific interference colors by using light interference. However, there have been problems such as limitations on the shape of the base material, limitations on the color tone, high costs, and wear. In the method of arbitrarily forming an interference color pattern, the method of forming a hologram foil by hot stamping is a method of forming a rubber stamp for the stamped pattern.
Alternatively, it is possible to form a part of the shaft by engraving, but if the shaft is inclined or has irregularities, the pattern may be deformed or the pattern may be formed in the concave part. Can not. In addition, there is a problem that seams can be formed when forming in the entire circumferential direction. The color tone is
Due to the structure of the hot stamping foil, the metal color of aluminum was the underlying color, and was monotonous iridescent.

[0005] A method of forming a transparent resin layer containing a pearl pigment by a coating method or a printing method is based on a color tone of a base.
Is affected by the color of the pigment. When a bright color such as white or pastel is used as a base, interference colors are hardly generated. Further, the same phenomenon occurs when the light reflection on the plating surface is large. As described above, there is a problem that the color tone of the base is restricted. Further, even if the base color tone can be adjusted, the color tone becomes unique to the pearl pigment, and it is impossible to express the interference color tone. In the method using ion plating, it is possible to form an interference color pattern by performing masking, but it is necessary to perform masking for forming a pattern or to adjust an underlayer for forming a film. Or large-scale equipment was required, which made it unsuitable for mass production and high cost. In addition, the film is several μm
Or it was not as durable as it was thin.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a decorative body which can express not a single color tone but an arbitrary interference color pattern with good reproducibility at low cost. Or, a decorative body in which a single or a plurality of transparent resin layers containing at least a pearl pigment having a high light transmittance is formed on a base material on which a colored pattern having a larger number of colors is formed.
The second aspect is a decorative body in which a colored resin layer containing a colorant through which light can pass is formed on a base material on which a hologram foil layer is formed.

Hereinafter, the present invention will be described in detail with reference to the drawings. 1 and 2 are views schematically showing the first invention.
1 in the figure is a base material. The material of the substrate 1 is a metal such as copper or copper alloy, aluminum or aluminum alloy, stainless steel, or ABS, AS, nylon, PE,
It is a thermoplastic resin such as acrylic or vinyl chloride. When the base material is metal, use a material processed into an arbitrary shape by a method such as pressing or cutting, and in the case of a thermoplastic resin, a material formed by various injections or extrusions, or cutting. Use the one that has been processed.

[0008] Reference numeral 2 in the figure denotes a plurality of colored layers. The coloring layer 2 is formed by a coating method, a printing method, a plating method, an alumite method, or the like, alone or in combination of a plurality of methods. The coloring layer to be formed can form various color tones, and the combinations thereof are infinite. As an example, a pattern paint such as marble paint may be used. The shape of the pattern of the colored layer is not particularly limited. It may be a geometric pattern or randomly colored. When the base material is a metal, an appropriate forming method is selected depending on the material. When the substrate is a resin, it is possible to eliminate the formation of a colored layer. For example, it is also possible to partially color by extruding a material of a plurality of colors simultaneously during molding.

Reference numeral 3 in the figure denotes a transparent resin layer containing a pearl pigment. The transparent resin layer 3 may be formed using a commercially available synthetic resin paint or ink.
There is no limitation on the forming method. In particular, the formation of the transparent resin layer
A coating method, a screen printing method, and the like are preferable in terms of ease of construction and cost. A coloring material such as a dye or a pigment may be dispersed in the transparent resin layer to further enhance the decorative effect. As the colorant to be dispersed, a commercially available colorant may be used, and the type and material are not limited. In particular, in order to enhance the decorative effect, the concentration of the coloring material is preferably lower, and more preferably 50% by weight or less based on the solid content of the resin. This is necessary to maintain the strength of the transparent resin layer. Further, the transparent resin layer may be formed on the entire surface by using a coating material in which a single pearl pigment is dispersed (see FIG. 1), or may be formed by using a coating material in which pearl pigments of different colors are dispersed. It may be partially formed a plurality of times so as not to overlap as much as possible (see FIG. 2).

Reference numeral 4 in the drawing denotes a pearl pigment. As the pearl pigment 4, a commercially available pearl pigment may be used.
The particle size is not limited. In order to enhance the decorative effect, an interference color pal pigment (having a high light transmittance) is particularly preferred.
The addition amount of the pearl pigment is 0.5 to 5 with respect to the resin solid content.
0% by weight is preferred. If the addition amount is less than 0.5% by weight, pearly luster may not be obtained, and if it exceeds 50% by weight, interference color tone may not be obtained.

FIG. 3 is a diagram schematically showing the second invention. In the figure, reference numeral 1 denotes a substrate, and the substrate 1 is the same as that of the first invention. 5 in the figure is a hologram foil. When the base material 1 is a metal, the hologram foil 5 is made of, for example, a thermoplastic resin such as chlorinated polypropylene, vinyl chloride, vinyl acetate, or acrylic resin, a urethane resin, or an epoxy resin in order to stably adhere the hologram foil to the base material 1. resin,
A resin layer 6 such as a thermosetting resin such as a melamine resin or an acrylic resin, or a solvent type hot melt resin is formed. When the substrate 1 is made of ABS, AS, polycarbonate, polyethylene or polypropylene resin, a primer layer such as chlorinated polypropylene resin may be provided according to the type of the resin.

Reference numeral 7 in the drawing denotes a resin layer containing a coloring material such as a dye or a pigment to such an extent that light is transmitted. As a coloring material,
What is conventionally used may be used, and the concentration thereof is such that light is transmitted. In the case of a dye, it varies depending on the color tone, but it is 0.1% by weight to 5% by weight based on the resin solid content. Should be fine. In the case of a pigment, it may be about 0.1% by weight to 3% by weight based on the resin solid content. If the concentrations of the dye and the pigment are too high, the light transmittance of the resin layer containing the dye and the pigment decreases, and the interference color of the hologram layer laminated on the base material becomes difficult to see, giving a rainbow color. It is not preferable because a deteriorated appearance cannot be obtained. Further, a plurality of these dyes and pigments may be mixed and used. These colored resin layers may have a single or a plurality of arbitrary patterns or uniform patterns formed thereon, or may have a multilayer structure.

The resin used for the resin layer 7 containing a coloring material to the extent that light is transmitted will be described. As the resin material, any resin having high transparency may be used, and a thermoplastic resin, a thermosetting resin, or an ultraviolet curable resin is used. In the case where a thermoplastic resin is used, a thermosetting or ultraviolet-curing transparent resin layer may be formed on the resin layer containing a coloring material to the extent that light is transmitted in order to increase durability.

[0014]

According to the present invention, since a transparent resin layer containing a single or a plurality of color pigments is formed on a substrate on which a pattern of a plurality of colors is formed, an arbitrary interference color pattern can be obtained. Can be expressed. Further, since a colored resin layer containing a colorant through which light can pass is formed on the base material on which the hologram foil layer is formed, a deep iridescent color can be developed, and the seam becomes inconspicuous. And a decorative body having an arbitrary interference color pattern can be obtained at low cost and with good reproducibility.
