Abstract of the disclosure A coatinag composition comprising as resinous vehicle, a melamine resin and a crosslink curable type resin having functional groups capable of reacting with said melamine resin, which is characterized by that the said 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 group being 2.0 and more, and the ratio of methylol number to imino number being 1.0 to 2.5. The coating composition is characterized by having, inter alia,a low temperature curing property and being excellent in intercoat adhesion. |
