To provide a latex having a sufficiently low viscosity at the time of neutralization of a copolymer latex obtained by emulsion polymerization, excellent workability, and exhibiting strength in an alkaline region. A copolymer latex obtained by emulsion polymerization, wherein the copolymer comprises at least an aliphatic conjugated diene monomer, an ethylenically unsaturated carboxylic acid monomer, and a vinyl cyanide monomer. A copolymer latex that is composed of the monomer component and causes the irreversible shape change of the copolymer particles due to a pH change from a weakly acidic or neutral region to an alkaline region.
