PURPOSE:To provide the title composition excellent in weather resistance, stain resistance and abrasion resistance, which comprises a graft polymer obtained by polymerizing a (meth)acrylic fluoroalkyl ester, a functional (meth)acrylic alkyl ester and a specific macromonomer, and a curing agent. CONSTITUTION:The title curable composition comprises a graft polymer (A) obtained by polymerizing 3-90wt.% (meth)acrylic fluoroalkyl ester monomer (a), 5-30wt.% functional (meth)acrylic alkyl ester monomer (b) and 5-90wt.% macromonomer (c) having a radical-polymerizable double bond and a molecular weight of 800-10,000, and a curing agent (B) having a functional group reactive with the polymer (A) (e.g., hexamethylene diisocyanate). This composition is quite suitable as a coating agent having stain resistance and weather resistance for buildings, cars, railway vehicles, air planes, ships, electric articles, etc., or as a binder composition for magnetic recording media. |
