DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a random uneven pattern.
More particularly, the present invention relates to a decorative body having a pattern for improving aesthetics and a method for manufacturing the same, and is suitable for use as a barrel for a writing instrument, a container for a makeup tool, and the like.

[0002]

2. Description of the Related Art Hitherto, the formation of a random uneven pattern has been realized by a decorative paint called cracking coating. The principle of the random uneven pattern is that the overcoat layer keeps the state of the film and agglomerates by the reaction between the layers caused by the gradient of the pigment concentration with respect to the resin concentration of the undercoat layer and the pigment concentration with respect to the resin concentration of the overcoat layer. It is because of that. Also, two-color patterns such as cracks are formed on the surface due to the difference in the pigment concentration between the concave and convex portions. However, the pattern that can be formed is only a combination of two colors, and at present, it is not possible to develop variations when considering multicoloring for improving aesthetics. Furthermore, the size of cracks and patterns is determined by the thickness of the undercoat layer, the drying conditions, and the thickness of the overcoat layer. This defect is a fatal defect when attempting to reveal the color of the undercoat layer from the crack. In addition, random pattern formation and multi-coloring are possible even by a method of patterning such as printing, hot stamping, combination processing by combination of plating, etc., tongue coating, marble coating, etc. The method has a problem that the surface is smooth and that the processing step is complicated and leads to an increase in cost.

[0003]

SUMMARY OF THE INVENTION According to the present invention, in order to improve the appearance, it is possible to simultaneously realize multicoloring and display of a random concavo-convex pattern, and to realize a reduction in cost due to simplification of the process. It is an object of the present invention to provide a decorative body that can be made and a method for manufacturing the same.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made by forming a plurality of steps on a substrate.
Colored layer, composed mainly of a resin and coloring material having a plurality of colors that are
A decorative body having a color transmitting layer, a discontinuous colored layer due to cracks in a coating film, and a clear protective layer formed in order as a first gist, painting, printing, hot stamping, plating, alumite, A colored layer of a plurality of colors is formed by physical vapor deposition or the like, and then a resin and a coloring material are mainly formed on the colored layer.
Forming a minute to color transmission layer treated by the liquid, by further forming a cracking left to the coating after application of the color transmission layer and the resin concentration and a coloring material concentration of different colored liquid the color transmissive layer A second aspect of the present invention is a method for manufacturing a decorative body in which a discontinuous colored layer having a random uneven pattern is formed, and then a clear protective layer is formed on the discontinuous colored layer by treatment with a resin solution. Things.

According to the present invention, cracks are generated on the surface by a simple process of coating two layers of two kinds of liquids having different resin concentrations and colorant concentrations without complicated processing steps. A random uneven pattern having various variations can be formed, and a plurality of colors of the colored layer can be seen through a crack, thereby achieving multicoloring in combination with the surface color. be able to.

The present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram schematically showing a decorative body of the present invention. Reference numeral 1 is a substrate, 2 is a colored layer, 3 is a color transmitting layer, 4 is a discontinuous colored layer, and 5 is a clear protective layer. Examples of the material of the base material 1 include metals such as iron, stainless steel, aluminum, copper and copper alloys, zinc alloys, ABS, AS, PP, PE,
Various materials such as synthetic resin such as PC and wood can be used. The base material 1 may be subjected to pretreatment by polishing, washing, or other chemical, mechanical, or physical means.

The colored layer 2 is formed by one or a combination of two or more treatments such as painting, printing, hot stamping, plating, alumite, and physical vapor deposition. It is important to form a plurality of colors if necessary, such as forming stripes, spots, tongues, and other patterns.

The color transmission layer 3 is made of epoxy, urethane,
Resin such as acrylic, acryl-melamine, alkyd, polyester, etc. as main component (resin content 55%
65% by weight) and several weight% of coloring materials such as pigments and dyes.
It was added and colored lightly.

The discontinuous colored layer 4 is made of a resin such as an epoxy-based, urethane-based, acrylic-based, acryl-melamine-based, alkyd-based, or polyester-based resin, and a pigment or dye-based resin. A colorant as a main component (resin content 15 wt% to 20 wt%, colorant 25 wt%
35% by weight) is a layer coated with a liquid (paint or ink). This liquid is used for the color transmission layer in the color transmission layer.
A resin concentration and a colorant concentration different from the resin concentration and the colorant concentration (specifically, the resin concentration of the liquid in the color transmission layer is 5%).
15% to 20% by weight when 5% to 65% by weight
The colorant concentration of the liquid in the color transmission layer is 0.1
(Weight% to 5% by weight, about 25% to 35% by weight). Due to this difference in concentration, the coating film causes a diffusion phenomenon between layers, and cracks (cracking)
As a result, a random uneven surface is formed, and a plurality of colors can be seen through the cracks, thereby realizing multicoloring.

The clear protective layer 5 is a transparent resin liquid (paint or ink) such as a thermosetting type or an ultraviolet curing type.
It is formed by spray painting, printing or the like. In order to further improve surface variations, a transparent resin solution contains a matting material or a coloring material such as a pigment or a dye at a weight percentage of several percent.
To tens of weight% may be added.
