Abstract
The present invention provides a coating composition that has excellent storage stability and that is capable of forming a coating film having excellent water resistance, chemical resistance such as gasohol resistance and fuel resistance, and adhesion. The coating composition comprises an acid-modified polyolefin (A), a coumarone-indene resin (B), and a hydrocarbon-based solvent (C), wherein the coumarone-indene resin (B) is contained in an amount of 25 to 400 parts by mass, per 100 parts by mass of the acid-modified polyolefin (A). The coating composition further comprises at least one of an ester-based solvent or ketone-based solvent (D).
Claims6
