Patent ID: 8519027

Claim:
An aqueous amino resin dispersion (A) comprising: a polyester resin (a) having a hydroxyl value within a range of 30-100 mgKOH/g, an acid value within a range of 20-80 mgKOH/g and a number-average molecular weight of 2,000-5,000, and a hydrophobic amino resin (b), wherein the polyester resin (a) and the amino resin (b) comprise solid components, wherein the weight ratio between the solid components of the polyester resin (a)/amino resin (b) is within a range of 5/95-49/51, and wherein the polyester resin (a) is prepared by a process consisting of an esterification reaction of a polyhydric alcohol (a-1) comprising at least as a part thereof, a compound having at least two hydroxyl groups per molecule and an anionic group-forming functional group, a polycarboxylic acid and/or polycarboxylic anhydride (a-2), and a monoepoxide compound (a-3) having one epoxy group and one chain or cyclic hydrocarbon group having 6-20 carbon atoms per molecule, and optionally followed by urethanation of the polyester resin (a).
