PURPOSE:Title coating that is composed of a specific acrylic copolymer, an amino resin and a polyfunctional isocyanate, thus giving the coating surface on the thermosetting resin moldings by baking that is suitable for finishing coating and applying patterns. CONSTITUTION:The objective coating comprises (A) a copolymer contsining (a) acrylic or methacrylic acid or their ester of formula I (R<1> is H, methyl; R<2> is H, alkyl) and (b) acrylic or methacrylic hydroxyalkyl ester of formula II (R<3> is alkylene) in more than 80wt% calculated as monomer units and having 500-10,000 average molecular weight and 80-400 hydroxyl value, and (B) (a) an amino resin as etherified methylol melamine and/or (b) a polyfunctional isocyanate as tolyenediisocyanate. |
