Abstract
PURPOSE: To obtain a heat-resisting aq. coat composition excellent in film-forming property and luster of a formed film, by dispersing a reaction product from an aluminum chelate compd. and a carboxyl group-contg. resin in an aq. medium.
CONSTITUTION: After an aluminum chelate compd. is reacted with a carboxyl group-contg. resin in an org. solvent, the org. solvent is distilled off. The obtd. reaction product is dispersed in an aq. medium in the presence of a basic substance. The carboxyl group-contg. resin is an acrylic resin, a styrene-maleic acid copolymer resin, a carboxyl group-contg. polyamide resin, etc. These resins have carboxyl groups content of pref. 50W300 in terms of acid value. A resin of acid value <30 is not pref. because of inferior water-dispersibility of the chelated resin, while use of a resin of exceedingly high acid value has defect of deteriorated water resistance of a film obtd. from the coat composition.
