Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material sheet having an uneven embossed pattern therein and rich in three-dimensional effect, and a method for manufacturing the decorative material sheet.

[Conventional technology]

For the purpose of obtaining a decorative material sheet having a three-dimensional effect, a material in which an embossed pattern with irregularities is formed on the surface of the decorative material sheet is used. For example, a decorative material in which an irregular pattern by an embossing roll is applied to the surface Sheets are used.

[Problems to be solved by the invention]

However, the decorative material sheet in which the concavo-convex pattern by the conventional embossing roll is applied to the surface has a certain three-dimensional effect, but does not have a three-dimensional effect that can be entirely satisfied. For example, when a decorative material sheet printed with a wood grain pattern is compared with a decorative material made of natural wood,
There is a drawback that the three-dimensional effect is not sufficient and the quality is inferior.

In addition, when the decorative material sheet is subjected to hot pressing again, the embossed pattern of the unevenness disappears due to the hot pressing. Therefore, when a backing material is laminated on the decorative material sheet by hot-press molding, a decorative material sheet having a three-dimensional effect cannot be obtained. In addition, when a new embossed pattern is provided on the surface opposite to the face having the embossed pattern of the decorative material sheet by hot pressing, the first uneven pattern disappears, However, it is not possible to obtain a decorative material sheet having an uneven pattern.

On the other hand, the present invention provides a decorative material sheet having a rich three-dimensional effect and various design effects, and a method for producing the same.
