ABSTRACT:
A resinous composition for two-liquid type water paint crosslinkable at the normal temperature which has a long pot life and which is superior in properties such as hardness, gloss, solvent resistance and water resistance is disclosed. A resinous composition comprises: (A) a colloidal dispersion or emulsion obtained by copolymerizing a monomer mixture comprising a carbonyl group-containing unsaturated monomer, carboxyl group-containing unsaturated monomer and other unsaturated monomers to form a copolymer, neutralizing the copolymer with an alkali, dissolving or emulsifying it into water, and adjusting the pH to above 7; and (B) an easily water soluble dihydrazide compound having from 1 to 5 carbon atoms.
