PURPOSE:To simultaneously prevent a color layer from being cracked and faded by a light, esp. by an ultraviolet light by a method wherein a material is colored with various colors by incorporating a specific amount of carbon black in a black polyolefin layer and incorporating a coloring pigment, a specific amount of sebacate, and others in a color polyolefin layer. CONSTITUTION:A black polyolefin layer 5 containing 0.1-5wt.% carbon black and a color polyolefin layer 6 are laminated in order through a modified polyolefin adhesive layer 4; the color polyolefin layer 6 contains 0.1-10wt.% coloring pigment, 0.1-2wt.% bis(2, 2, 6, 6-tetramethyl-4-piperidyl)sebacate, and 0.1 2wt.% poly[{6-(1,1,3,3tetramethylbutyl)imino-1,3,5-triazine-2,4 diyl} {(2,2, 6,6-tetramethyl-4-piperidyl)imino} hexamethylene {(2, 6,6-tetramethyl-4-piperidyl) imino}]. |
