PROBLEM TO BE SOLVED: To obtain an aq. resin compsn. excellent in moistureproofness, etc., by incorporating an aq. dispersion contg. a carboxylated styrene-acrylic copolymer and a polyvalent metal complex salt, a synthetic styrene-butadiene rubber latex, an ethylene-acrylic acid copolymer with a specified average mol.wt., and a low-molecular hydrocarbon resin with a specified average mol.wt. into the same. SOLUTION: This compsn. contains 65-15 wt.% (solid content basis) aq. dispersion contg. a carboxylated styrene-acrylic copolymer and a polyvalent metal complex salt, 5-25 wt.% (solid content basis) synthetic styrene-butadiene rubber latex, and 20-60 wt.% sum of an ethylene-acrylic acid copolymer which has an average mol.wt. of 10,000-30,000 and an acid value of 100-200 and a low- molecular hydrocarbon resin (e.g. polybutene) which has an average mol.wt. of 500-5,000 and is liq. at normal temp., the sum of all the above ingredients being 100 wt.%. The compsn. is excellent in resistances to wet blocking and hot blocking.
