PROBLEM TO BE SOLVED: To obtain a copolymer latex having high long-term storage stability without emitting any substance causing indoor air pollution( sickhouse ). SOLUTION: The copolymer latex is obtained by emulsion polymerization of a monomer mixture comprising 50-80 pts.wt. of an aliphatic conjugated diene monomer, 20-50 pts.wt. of a vinyl cyanide-based monomer and 0-10 pt(s).wt. of an ethylenically unsaturated carboxylic acid monomer. This copolymer latex contains, based on 100 pts.wt. thereof in terms of solids,≥0.001 pt.wt. of a benzoisothiazoline-based compound of the general formula(1) and≥0.001 pt.wt. of a 2-methyl-4-isothiazolin-3-one, being -100 mV to +300 mV in oxidation-reduction potential.
