ABSTRACT:
It is an object of the present invention to provide a base coating composition for decorated moldings containing silver plating layer and a top clear coating composition for decorated moldings containing silver plating layer, and decorated moldings obtainable by using these compositions; the compositions and moldings are to be excellent in silver deposition tendency, basecoat film smoothness, adhesion and/or film appearance.A base coating composition for decorated moldings containing silver plating layer comprisinga main composition for base coating comprising an acrylic polyol (A1), an organic-modified polydimethylsiloxane (A2) and an epoxysilane (A3) represented by the chemical scheme (1):in the scheme, R1represents a methyl, methoxy or ethoxy group and R2and R3are the same or different and each represents a methoxy or ethoxy group, and a curing agent for base coating comprising a polyisocyanate,wherein the base coating composition for decorated moldings is a two-package curing type urethane coating composition, in the main composition for base coating, the (A2)/(A1) ratio is 0.02/100 to 0.20/100 on the solid weight basis and the (A3)/(A1) ratio is 1.5/100 to 5.5/100 on the solid weight basis, and the equivalent ratio between the NCO groups in the curing agent for base coating and the OH groups in the acrylic polyol (A1), namely the NCO/OH equivalent ratio, is 1.5 to 3.0.
