发明名称 POLYCARBONATE RESIN LAMINATE EXCELLENT IN ACTUAL EXPOSURE WEARTHERABILITY
摘要 PROBLEM TO BE SOLVED: To provide a plastic molded object of which the surface is protected by a cured coating film imparting high actual exposure weatherability and which has a capacity also excellent in abrasion resistance. SOLUTION: A laminate is obtained by successively laminating an acrylic resin layer (first layer) and a cured layer (second layer) of a composition containing an organosiloxane resin containing colloidal silica on at least one surface of a transparent polycarbonate resin sheet. The first layer of the laminate satisfies formula (1) : 2≤d≤8, formula (2) : 0.1≤c≤0.5 and formula (3) : 0.6≤d x c≤3 and contains a chloroform solution with a concentration of 10 mg/L and a compound having ultraviolet absorption wherein light absorbance at a wavelength of 300 nm measured in a light path length of 1.0 cm is not less than 0.25. In formulae (1)-(3), d is the film thickness of the first layer shown byμm and c is the concentration of a unit originating from a compound having ultraviolet absorbance shown by g/cm<SP>3</SP>in the first layer.
