    摘要: 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.gtoreq.(A-1)/B.gtoreq.15/85 (I)1.ltoreq.(D)+(A-2).ltoreq.80 (II)1.ltoreq.(D).ltoreq.80tm (III).

    摘要: A process is disclosed for preparing a composition comprising a polybutyl ketone and a hydroxyester of an epoxidized polybutene wherein the epoxide groups of said epoxidized polybutene are at least 70% trisubstituted. Acid compounds are reacted with epoxidized polybutenes to obtain compositions of increased reactivity as compared with polybutyl ketone compounds. These compositions are useful as chemical intermediates to modify such materials as polyesters and polyurethenes, for applications such as coatings, foams, and sealants.
