Abstract
A composition for water-base paints, said composition comprising (I) a water-soluble resin, and (II) a water-dispersible polymer containing at least one group selected from the class consisting of hydroxyl and carboxyl groups, said water-soluble resin being obtained by polymerizing 50 to 99.5% by weight of an alkyl ester of an .alpha.,.beta.-monoethylenically unsaturated acid or an alkenyl benzene, 0.5 to 20% by weight of an .alpha.,.beta.-monoethylenically unsaturated acid and 0 to 30% by weight of a hydroxyalkyl ester of an .alpha.,.beta.-monoethylenically unsaturated acid in the presence of at least one unsaturated compound selected from the group consisting of alkyd resins containing a polymerizable unsaturated group, epoxy esters containing a polymerizable unsaturated group, drying oils, fatty acids of drying oils and diene polymers, and water-solubilizing the product with ammonia or an amine.
