PURPOSE: To enhance weatherability and recycling properties by performing the co-extrusion of an acrylic resin so that the thickness of a laminated part is 1-10μm and the ratio of the laminated part becomes 0.5% or less of the whole of a molded product and adding an ultraviolet absorber to the acrylic resin of the laminated part in specific concentration.

CONSTITUTION: An acrylic resin is subjected to co-extrusion so as to be laminated to the surface of a polycarbonate resin so that the thickness of a laminated part becomes 1-10μm and the ratio of the laminated part becomes 0.5% or less of the whole of a molded product and the acrylic resin of the laminated part contains an ultraviolet absorber in concn. satisfying formula, that is, thickness (μm) of the laminated part x ultraviolet ray absorbent concn. (%)=0.5-50. As the acrylic resin used in the laminated part, a general grade acrylic resin and an impact-resistant acrylic resin are suitable. The ultraviolet absorber is selected from a benzotriazole type, a 2-hydroxybenzophnone type and phenyl salicylate type ultraviolet absorbers. By this method, weatherability can be improved and recycling properties at the time of manufacturing can be improved.
