The present invention can provide the aqueous coating composition of fluorine-containing copolymer being excellent in long-term weather resistance and useful for the interior and exterior of buildings and the aqueous dispersion composition of fluorine-containing copolymer which is used for the aqueous coating composition. The aqueous coating composition of fluorine-containing copolymer is prepared by dispersing in water the aqueous dispersion of fluorine-containing copolymer having hydroxyl and the water dispersible polyisocyanate compound.
An aqueous coating composition of fluorine-containing copolymer, wherein an aqueous dispersion of fluorine-containing copolymer having hydroxyl and a polyisocyanate compound dispersible in water are dispersed in water.
An aqueous dispersion composition of fluorine-containing copolymer which is used for an aqueous coating composition, characterized in that the aqueous dispersion composition comprises an aqueous dispersion of fluorine-containing copolymer obtained by emulsion-polymerizing from 10 to 400 parts by weight of a monomer mixture containing an alkyl acrylate having an alkyl group of from C1 to C18 and/or an alkyl methacrylate having an alkyl group of from C1 to C18 and an ethylenically unsaturated monomer copolymerizable with those esters in an aqueous medium in the presence of 100 parts by weight of fluorine-containing polymer particles to give copolymer particles having an average particle size of from 0.05 to 3 μm, in said monomer mixture, a monomer having hydroxyl being contained in an amount of from 0.1 to 50% by weight based on said monomer mixture.
An aqueous coating composition of vinylidene fluoride copolymer, wherein an aqueous dispersion of particles of vinylidene fluoride copolymer having hydroxyl and obtained by seed-polymerizing an acrylic monomer in the presence of particles of vinylidene fluoride copolymer as seed particles and a polyisocyanate compound dispersible in water are dispersed in water and the vinylidene fluoride copolymer of the seed particles contains from 55 to 98% by mole of vinylidene fluoride unit.
