COATING COMPOSITION AND RESIN PRODUCT HAVING LIGHT-TRANSMITTING PROPERTY

摘要

A coating composition which has high adhesion and can form a cured coating film on resinous bases although it is of the one-pack type. It can give an effective cured coating film having satisfactory dyeability on resinous bases with poor dyeability. The film is inhibited from blushing. Also provided is a resin product made with the composition. The coating composition comprises a polycarbonate diol as ingredient (A), colloidal particles of a metal oxide as ingredient (B), an organosilane hydrolyzate as ingredient (C), and a solvent as ingredient (D). The polycarbonate diol functions as an adhesion accelerator and helps the formation of a cured coating film on a resin molding without necessitating application of a primer. Since the polycarbonate diol functions also as a dyeability imparter, the dyeability of the coating film can be regulated by changing the amount of the diol.
