Abstract
The present invention is to provide a coating composition capable of forming a protective film excellent in adhesion properties. Such a coating composition comprises a specific polymer containing carboxyl group, a specific multifunctional epoxide-containing compound having two or more epoxy groups, an organic solvent, and an amino-containing silane coupling agent represented by the following general formula (I): H2N—R1—Si—(OR2)3 (I) wherein, R1 is an unsubstituted alkylene group, and R2's are independently an unsubstituted alkyl group.
Claims8
A coating composition comprising:
- (A) at least one polymer containing carboxyl group, having a weight-average molecular weight, as calculated in terms of styrene, of 5,000 to 200,000, an acid value of from 10 to 300 mgKOH/g, and a glass transition temperature of 50 to 250° C.;
- (B) as a crosslinking agent, a multifunctional epoxide-containing compound having at least one benzene ring or heterocycle, and two or more epoxy groups;
- (C) an organic solvent;
- and
- (D) at least one amino-containing silane coupling agent represented by the following general formula (I):
- H2N—R1—Si—(OR2)3 (I)
- wherein, R1 is an unsubstituted alkylene group, and R2's are independently an unsubstituted alkyl group.
