Abstract
Disclosed is a curable fluorine-containing copolymer, comprising 25-75 mol % of first repeating units which originate from chlorotrifluoroethylene, 10-70 mol % of second repeating units which originate from a vinyl or isopropenyl ester of fatty acid, such as vinyl acetate or isopropenyl acetate, 3-40 mol % of third repeating units which originate from a hydroxyl-containing allyl ether such as ethylene glycol monoallyl ether and 0-20 mol % of optional repeating units which originate from an optional monomer such as an acrylate. This copolymer possesses favorable properties characteristic of fluoro-resins, is soluble in organic liquids and is curable with a compound having a functional group that reacts with active hydrogen, such as a polyisocyanate. A coating liquid composition obtained by adding such a curing agent to a solution of the copolymer in an organic solvent is of wide use for painting and other coating purposes.
