Abstract

To provide an aqueous resin composition including: an anionic polyurethane (A) having an aromatic ring; an acrylonitrile butadiene rubber (B); an aqueous medium (C); a vulcanizing agent (D); and a vulcanizing accelerator (E). The anionic polyurethane (A) is preferably a product of reaction of polyoxytetramethylene glycol, a carboxyl group-containing glycol, ethylene glycol, and diphenylmethane diisocyanate, or a product of reaction of polyoxytetramethylene glycol, a carboxyl group-containing glycol, butanediol, and diphenylmethane diisocyanate. An object of the invention is to provide a mixture of aqueous polyurethane and NBR having excellent storage stability, even in a case where the vulcanizing agent and the vulcanizing accelerator are added.
