ABSTRACT:
A method of treating the surface of a shaped article of a polycarbonate resin, which comprises coating the shaped article of the polycarbonate resin with a specific pre-treating solution (I), air-drying the coated article, then coating the article with a specific coating composition (II), and heat-curing the coated article. The pre-treating solution (I) contains a bisphenol type epoxy resin in a mixed solvent of a lower alcohol and an alkyl ether of ethylene glycol, and the coating composition (II) comprises (A) a reaction mixture of an aminoalkylalkoxy silane of the formula (1) with an epoxyalkylalkoxy silane of the formula (2); (B) a mixture of an alkyl-modified methylol melamine of the formula (3) with an alkyd resin; and (C) an acrylic acid derivative of the formula (5) or its polymer of a low degree of polymerization, the formulas (1), (2), (3) and (5) being given in the claim.
