<p>PURPOSE:To permeate an iris having elegance, beauty, clearness and high luminousness by providing a deposited thin film structure sequentially formed of a low reflectivity metal or metal compound deposited thin film, a low refractive index metal oxide deposited thin film and a high reflectivity metal or metal compound deposited thin film between transparent or translucent protective layer and colored layer. CONSTITUTION:A laminate is formed by forming a mold release agent layer 3 on a base material 2 and sequentially laminating a transparent or translucent first protective layer or colored layer 4, a transparent or translucent functional resin layer 5 and a second protective layer or colored layer 6 made of transparent or translucent resin in this order. A deposited thin film structure 7 and a third protective layer or colored layer 11 are formed thereon. Iris powder is obtained by pulverizing the residual laminate after the material 2 is peeled from the laminate 1. The structure 7 is formed by combining a low reflectivity metal or metal compound deposited thin film 8 having 15-35% reflectivity, a low refractive index metal oxide deposited thin film layer 9 having a refractive index of 0.5-2.5 and a high reflectivity metal or metal compound deposited thin film layer 10 having reflectivity of 75-98% in this order.</p> |
