POLYCARBONATE RESIN LAMINATED BODY WITH EXCELLENT WEATHERABILITY AND METHOD FOR MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a polycarbonate resin laminated body with excellent weatherability with adding a small amount of an ultraviolet light absorber. SOLUTION: The polycarbonate resin laminated body (C) is a laminated body wherein a polycarbonate resin (B) layer comprising a high concentration ultraviolet light absorber is laminated on at least one face of a polycarbonate resin (A) layer by co-extrusion so that a mean thickness on one face calculated from an amount of discharging is 20-100 μm, and the concentration of the ultraviolet light absorber has a concentration gradient satisfying an equation (1) 15X0.2≤Y≤15X0.5on the neighborhood of the interface of the layer (A) and the layer (B), wherein X is a thickness (μm) of a layer in which the concentration of the ultraviolet light absorber is ±10% to a mean concentration of the ultraviolet light absorber from the outermost surface layer of the layer (B) to a depth of 10 μm, and Y is a thickness (μm) of a layer in which the concentration gradient exists from -10% to the mean concentration of the ultraviolet light absorber from the outermost surface layer of the layer (B) to a depth of 10 μm to +10% of the concentration of the ultraviolet light absorber to the mean concentration of the ultraviolet light absorber of the layer (A).
