Abstract
Abstract A thermosetting composition (A) a hydroxyl group-containing resin, (B) an alkoxysilane group-containing copolymer and (C) a curing catalyst. The film of the composition is excellent in not only adhesion, gel percentage and surface hardness but also solvent resistance, acid resistance, and stain resistance.
