Document Type and Number:

WIPO Patent Application WO/2018/043586

Kind Code:

A1

Abstract:

Provided is a chloroprene rubber latex adhesive composition which exhibits excellent initial adhesive strength and normal adhesive strength, and exhibits excellent thermal creep resistance with respect to an adherend. This chloroprene rubber latex adhesive composition includes (A) a carboxy-modified chloroprene-based copolymer latex that contains polyvinyl alcohol and a copolymer of a chloroprene monomer and an ethylenically unsaturated carboxylic acid, (B) a chloroprene-based polymer latex that contains a metal salt of a rosin acid, and a chloroprene-based homopolymer or a copolymer of a chloroprene monomer and another monomer, and (C) a chlorinated polyolefin resin emulsion, wherein the content ratio of the carboxy-modified chloroprene-based copolymer latex (A) and the chloroprene-based polymer latex (B) is 80:20 to 20:80 in terms of solid content ratio.
