A curable composition useful in water-based paints comprises a water-based product obtained by dispersing or dissolving in water a vinyl polymer (II) containing tertiary amino and/or acidic groups which have been neutralized by an acidic or basic compound, an epoxy and hydrolysable silyl groups-containing compound (B), and a hydrolysable silyl and/or silanol groups-containing compound (F).

Water-based neutralized tertiary amino and/or acidic vinyl polymer with epoxy and hydrolyzable silyl compound

Curable resin composition for use in water-based coating materials

The present invention proposes highly practical curable resin compositions for use in water based paints, which contain no, or much less organic solvent when compared with current organic solvent based paints, and which produce painted surfaces which have excellent curability and weather resistant properties, as well as excellent resistance to solvents, chemicals and water. These curable resin compositions include a compound combining both epoxy and hydrolyzable silyl groups, and a water based product obtained by dispersing or dissolving in water, a tertiary amino vinyl polymer, a vinyl polymer containing both tertiary amino and acidic groups, or an acidic vinyl polymer, which has been either partially or completely neutralized by an acidic or basic compound.
