Description

  The present invention relates to a novel laminate. The laminate of the present invention can be applied to surface coverings such as buildings and civil engineering structures, and specifically, can be applied to pattern finishing of building wall surfaces.

  In the building wall surface, etc., aesthetics are required from the viewpoint of landscape. In recent years, from such a viewpoint, for example, a pattern finish inspired by natural stone has attracted attention.

The pattern finish obtained in Patent Document 1 is a spot-like coating film formed by sputtering. Patent Document 2 describes a method of spraying a large number of paint droplets by sputtering after applying a base color coating to a surface to be coated.
