To provide a neoprene latex adhesive composition excellent in initial adhesive strength and normal adhesive strength, and excellent in thermal creep resistance with an adherend. The chloroprene rubber latex adhesive composition contains: a carboxyl group-modified chloroprene-based copolymer latex (A), a chloroprene-based polymer latex (B) and a chlorinated polyolefin resin emulsion (C), and the The carboxyl-modified chloroprene-based copolymer latex (A) contains a copolymer of a chloroprene monomer and an ethylenically unsaturated carboxylic acid, and polyvinyl alcohol, and the chloroprene-based polymer latex (B) ) containing a chloroprene homopolymer or a copolymer of a chloroprene monomer and other monomers and containing a metal rosin acid salt, the aforementioned carboxyl-modified chloroprene-based copolymer latex (A) and the aforementioned chloroprene The content of the vinyl polymer latex (B) is 80:20 to 20:80 in terms of solid content conversion ratio. |
