PROBLEM TO BE SOLVED: To control the touch of profundity and gloss of a color tone by forming at least one kind selected from a metal, a metallic colloid and a metallic compound on a base material and further, forming a transparent resin layer on at least one kind of the metal, metallic colloid or the metallic compound. SOLUTION: A metallic layer 2 is a metallic layer formed of at least one kind selected from a metal, a metallic colloid and a metallic compound formed on a base material 1. The thickness of the metallic layer 2 is such as is capable of controlling the reflection, refraction and transmission of light by transmitting the light through the layer 2. The incident light transmitted through a transparent resin layer is separated into a reflected light and a transmitted light. The transmitted light proceeds while being partially absorbed by the resin layer and reaches the metallic layer. The reaching light is again separated into the reflected light and the transmitted light. The reflected light is separated into the light transmitted through the resin layer coming out into the air and the light reflected by an interface between the transparent resin and the air. The light transmitted through the metallic layer reaches the surface of the base material 1 almost without being absorbed. Thus it is possible to control the color tone and the touch of profundity and gloss by the diversion of a light path and the reflection, refraction and transmission phenomena. |
