Abstract
Abstract The present invention relates to a coating composition which is excellent in handling and safety, enables the curing of the resultant coating composition at low temperature, and provides an excellent adhesion to polyolefin resin moldings. The coating composition comprises (1) 40-90 wt. % of a grafted and chlorinated polyolefin oligomer obtained by graft polymerizing a vinyl polymerizable monomer to a chlorinated polyolefin, the grafted and chlorinated polyolefin oligomer having a primary or blocked primary hydroxyl group at a position of 15 to 40 atoms away from the vinyl graft polymer chain grafted to the chlorinated polyolefin, a number average molecular weight of 5,000 to 50,000, 0.4 to 2.5 mole/kg-resin of a primary or blocked primary hydroxyl group, 50 to 95 wt. % of said vinyl graft polymer chain, and 5 to 50 wt. % of the chlorinated polyolefin used as a starting material, and (2) 60 to 10 wt. % of an imino-type, methylol-type or complete alkoxy-type melamine resin. The present coating composition can be cured by baking the coating composition at 90° to 120° C.
