ABSTRACT:
A coating composition comprising as resinous vehicle, a melamine resin, and a crosslink curable type resin having functional groups capable of reacting with the melamine resin, which is characterized in that the melamine resin has a weight-average molecular weight by Gel Permeation Chromatography of 6000 to 12000 and bears as functional groups, imino, methylol and alkoxymethylol groups, the sum of imino and methylol groups being, when expressed in terms of average number per triazine nucleus, 2.0 to 2.5, the number of alkoxymethylol groups being 2.0 or more, and the ratio of methylol groups to imino groups being 1.0 to 2.5.
The coating composition is characterized by having, inter alia, a low temperature curing property and excellent intercoat adhesion.
