Abstract
The curable composition comprising (A) an alkoxysilyl group-containing acrylic copolymer or a mixture therof with a hydroxyl group-containing acrylic resin, (B) a curing catalyst, (C) an organic solvent and (D) fine particles of a cross-linked polymer which is insoluble but stably dispersible in the components (A), (B) and (C), the cross-linked polymer (D) comprising (d1) a backbone polymer polymerized from a monomer mixture having mainly an alkyl acrylate and (d2) a grafted phase polymerized in the presence of the backbone polymer (d1) from a monomer mixtuer having mainly an alkyl methacrylate. The composition of the present invention is improved in sag resistance as well as excellent in durability and film appearance, so a satisfactorily thick film can be obtained by one application of the composition.
