Title:

WATER-BASE COATING RESIN COMPOSITION AND WATER-BASE COATING COMPOSITION

Document Type and Number:

WIPO Patent Application WO/1994/014905

Kind Code:

A1

Abstract:

A water-base coating resin composition substantially comprising a mixture of: (1) a reaction product (C) between an aromatic polyol resin (A-1) and a carboxylated acrylic resin (B), (2) an aromatic epoxy resin (D), and (3) another aromatic polyol resin (A-2), wherein the ratio of component (A-1) to component B by weight satisfies the relationship of the formula (I): 85/15 (A-1)/(B) 15/85, and the proportions of components (C), (D) and (A-2) satisfy the relationship of the formulae (II): 1 (D)+(A-2) 80 and (III): 1 (D) 80, the total weight of them being 100. A water-base coating composition is prepared by dispersing the above resin composition in an aqueous medium without using any organic solvent. The obtained coating composition is excellent in long-term stability and gives a coating film which is excellent in retorting resistance, adhesion to metal, processability and chemical resistance and can be cured at a comparatively low temperature.
