Abstract
PURPOSE: To prepare the title molded article having a UV-resistant and heat-resistant surface layer, by treating a polycarbonate resin molded article with specific mixed solvent containing a UV-absorbing agent.
CONSTITUTION: A polycarbonate resin molded article is dipped in a composition composed of 60W90 vol% of an N-dialkylamide compound of formula I (R1 is H, methyl; R2 is methyl, ethyl) and 40W10 vol% of a diol compound of formula II (n is ≥1) and/or water, and containing a UV-absorbing agent such as 2-hydroxy-4-methoxybenzophenone, diphenylmethylene cyanoacetic acid ethyl ester, etc., at 20W50°C, and dried by heating to 70W120°C.
