Abstract
A chloroprene copolymer latex containing a chloroprene copolymer having a structural unit derived from chloroprene and a structural unit derived from 2,3-dichloro-1,3-butadiene, in which a toluene insoluble content in the chloroprene copolymer is 50 to 95% by mass, and a modulus at 500% elongation of a film, which is obtained on a base material by dipping the base material in the chloroprene copolymer latex and then performing vulcanization at 100° C. for 30 minutes, according to JIS K 6251 is 4.0 MPa or less.
