The present invention provides an aqueous resin composition, characterized by containing: an anionic polyurethane (A) having an aromatic ring, an acrylonitrile butadiene rubber (B), an aqueous medium (C), a vulcanizing agent (D), and a vulcanization accelerator (E). The anionic polyurethane (a) is preferably a reaction product of polyoxytetramethylene glycol, a glycol having a carboxyl group, ethylene glycol and diphenylmethane diisocyanate; or reactants of polyoxytetramethylene glycol, glycols having carboxyl groups, butanediol and diphenylmethane diisocyanate. The problem to be solved by the present invention is to provide a mixture of an aqueous polyurethane and NBR which is excellent in storage stability even when a vulcanizing agent and a vulcanization accelerator are added. |
