摘要： Provided is a chloroprene rubber latex adhesive composition superior in initial adhesive strength and normal adhesive strength and also in thermal creep resistance with adherend. A chloroprene rubber latex adhesive composition includes a carboxy-modified chloroprene-based copolymer latex (A) containing a copolymer of chloroprene monomer and an ethylenic unsaturated carboxylic acid and a polyvinylalcohol, a chloroprene-based polymer latex (B) containing a chloroprene homopolymer or a copolymer of chloroprene monomer and other monomer and a rosin acid metal salt and a chlorinated polyolefin resin emulsion (C), wherein the content ratio of the carboxy-modified chloroprene-based copolymer latex (A) to the chloroprene-based polymer latex (B) is 80:20 to 20:80 as solid matter.
