    摘要: A resinous composition for water paint crosslinkable at the normal temperature is provided, which is suitable for painting interiors and exteriors of buildings, bridges, vehicles and et al, which is non-odored, as well as which has advantages in safe and hygienic aspects. A resinous composition for a water paint, which is obtained by blending an aqueous dispersion of a carbonyl group-containing copolymer (A) with a carbonyl group-containing aqueous polyurethane resin (B) at the ratio of 100 parts by weight of solids in (A) to 5.about.150 parts by weight of (B), and then adding as a crosslinking agent a hydrazide compound having at least 2 hydrazide groups per one molecule (C) at the ratio of 0.01.about.2 moles of (C) to 1 mole of carbonyl group contained in the said (A) and (B) components, wherein the said polyurethane resin (B) being obtained by copolymerizing an unsaturated polyurethane resin obtained by the reaction of a diisocyanate compound with a polyol having a number average molecular weight of 60.about.10,000, a carboxyl group-containing diol and a hydroxyl group-containing ethylenic unsaturated monomer with a carboxyl group-containing ethylene unsaturated monomer.
