Cosmetic materials and door using it {COSMETIC MATERIAL AND A DOOR USING THE SAME}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic material used for interiors and exteriors of buildings, vehicles, and the like, and more particularly, to a cosmetic material having a high-quality appearance by irregularities.

Background Art Conventionally, it is known that cosmetics of this kind are provided with unevenness on the surface to give a sense of quality. For example, in the door of a decorative steel plate, the thing which provided the design by forming a pattern shape by gravure offset printing is used. Moreover, what pressed by the metal mold and embossed is also used. Or the thing which provided the color or pattern which unevenness | corrugation which a unevenness | corrugation has on the surface by powder coating, and performed the design which has a change is used.

Of the cosmetic steel sheets as the above-described cosmetic materials, the patterned shapes are formed by silk screen printing, gravure offset printing, etc., and thus have a drawback in that they lack a sense of quality because they are monotonous with only a flat design. Alternatively, embossing with a mold press makes it possible to express the appearance of unevenness, but there is also a drawback in that the shape of the unevenness is monotonous, which also lacks a sense of quality, and the cost of the mold is very high. In addition, the unevenness formed by the powder coating is more varied than the embossing of the uneven appearance, but there is a drawback that the unevenness is not reproducible, and the unevenness is likely to occur.

The present invention has been made in view of the above problems, and the object of the present invention is that there is no nonuniformity because of reproducibility compared to mounting coating without using a mold press, and there are various variations and unevenness integrated with a pattern shape. To provide a cosmetic that can give a shape.
