PCT No. PCT/JP93/01844 Sec. 371 Date Aug. 18, 1994 Sec. 102(e) Date Aug. 18, 1994 PCT Filed Dec. 21, 1993 PCT Pub. No. WO94/14905 PCT Pub. Date Jul. 7, 1994.A water-based coating composition that does not use an organic solvent is formed by dispersing a resin composition into an aqueous medium. The water-based coating composition has excellent stability over time. The coating film obtained from the composition has excellent retort resistance, adhesion to metals, processability and chemical resistance; and it can be cured at relatively low temperatures. The resin composition consists essentially of: (1) a reaction product (C) of an aromatic polyol resin (A-1) and a carboxyl group-containing acrylic resin (B); (2) an aromatic epoxy resin (D); and (3) an aromatic polyol resin (A-2); wherein said aromatic polyol resin (A-1) and said aromatic polyol resin (A-2), which may be the same or different, are obtained by capping the epoxy group of an aromatic epoxy resin, the weight ratio of component (A-1) to component (B) satisfying the following expression (I), and the proportion of component (D) and component (A-2) satisfying the following expressions (II) and (III) based on 100 parts by weight of the resin mixture: 85/15>/=(A-1)/B>/=15/85(I) 1</=(D)+(A-2)</=80(II) 1</=(D)</=80tm (III).
