To provide a copolymer having excellent various properties such as flame retardance, workability and excellent feeling etc., without introducing vinyl acetate which causes a problem by generation of a decomposition product, a resin aqueous emulsion of a resin and a backing agent for treating a textile product.
The copolymer for solving the problem is obtained by subjecting 100 parts by mass of total monomers composed of 0.5-70 parts by mass of a phosphorus-containing monomer (A) having a specific structure containing a phosphoric acid ester group comprising a six-membered ring aromatic hydrocarbon as a substituent group and a monomer (B) being at least one kind selected from the group consisting of an aromatic vinyl-based monomer etc., different from the phosphorus-containing monomer (A) to copolymerization reaction. The resin aqueous emulsion having excellent various properties such as flame retardance, workability and excellent feeling, etc., and the backing agent for treating a textile product are obtained by using the copolymer as a component.
