<p>A curable resin composition for water-based paints comprising an emulsion polymer (A) bearing tertiary amino groups which is prepared by emulsion polymerizing a vinylic monomer having a tertiary amino group with other vinylic monomer in an aqueous medium and a compound (B) bearing both an epoxy group and a hydrolyzable silyl group as essential components and preferably containing an aqueous mixture (C) prepared by adding a neutralizing agent to a vinylic polymer (I) having acid groups and/or tertiary amino groups in such an amount as to neutralize at least 10 % of the acid groups and/or the tertiary amino groups and dispersing or dissolving the obtained mixture in water and/or a compound (D) other than the compound (B) which has a hydrolyzable silyl group and/or a silanol group. The paint prepared by using the composition is curable at ordinary temperatures and excellent in workability in coating and can give a cured coat excellent in the resistances to weather, solvents, chemicals, water and so on and reduced in environmental pollution.</p> |
