Abstract

PURPOSE:To obtain the title composition capable of forming a tough coating film excellent in food sanitation and flavor retentivity and suitable as a paint for an inner side of a can, by esterifying a reaction product obtained by polymerizing three specified polymerizable monomer components and an aromatic epoxy resin, neutralizing the product to a specified pH and finely dispersing it in water. CONSTITUTION:A reaction product is obtained by polymerizing 10-60pts.wt. polymerizable monomer component comprising 30-70wt.% COOH-containing vinyl monomer (a) such as (meth)acrylic acid, an aromatic vinyl monomer (b) such as styrene, and at least one monomer (c) selected from among alkyl esters, hydroxyalkyl esters and N-hydroxyalkylamides of alpha,beta-ethylenically unsaturated carboxylic acids and 90-40wt.% aromatic epoxy resin (B) in an alcoholic solvent in the presence of at least 3wt.%, based on component A, free radical generator. The product is esterified in the presence of an esterification catalyst, and part of the COOH groups of this product are neutralized with a basic substance to a pH >=5, and the neutralized product is finely dispersed in water.
