Abstract

An aqueous dispersion of a graft-copolymer (A), dispersed in water or a mixed solvent (B) of water and a water-soluble organic solvent, the graft-copolymer (A) comprising a polyester (A-a), which is obtained by copolymerizing a dicarboxylic acid having a polymerizable unsaturated double bond in a proportion of 0.5-10% by mole relative to an entire acid component graft-polymerized with a radical copolymerizable monomer (A-b) comprising a radical copolymerizable monomer having a hydrophilic group, in which thegraft-copolymer (A) is dispersed as fine particles having an average particle size of 10nm-500nm and a half band width of a signal of a carbon of a carbonyl group of the polyester, as determined by 13C-NMR, is 300- Hz; and in the graft-copolymer (A), the weight ratio of the polyester (A-a) to the polymer chain (A-b)' of the radical polymerizable monomer (A-b) is 40:60-95:5. The aqueous polyester dispersion of the present invention is superior in redispersibility and when a paint prepared from the dispersion is coated on a metal or a plastic, the coated film shows superior appearance, processability and water resistance. Accordingly, the aqueous dispersion of the present inventionserves well for use for paints, ink, coating agents, adhesives and various treating agents.
