Title: COPOLYMER LATEX
Abstract:
Provided is a copolymer latex which is a latex of a copolymer that contains 50-88% by weight of a conjugated diene monomer unit, 10-40% by weight of an ethylenically unsaturated nitrile monomer unit and 2-10% by weight of an ethylenically unsaturated acid monomer unit. This copolymer latex is configured such that the methyl ethyl ketone insoluble fraction is 70% by weight or less and the methyl ethyl ketone swelling degree is 40 times or more in cases where the copolymer is formed into a dry film.
