(57) [Summary] [Object] To provide a copolymer latex composition having excellent chemical and mechanical stability and excellent storage stability against microorganisms. The copolymer latex composition comprises (a) a conjugated diene compound of 10 to 65% by weight, (b) an aromatic vinyl compound of 0 to 70% by weight, and (c) an ethylenically unsaturated carboxylic acid of 0 to 10% by weight. %, (D) 100 parts by weight of a monomer composed of 0 to 40% by weight of another copolymerizable monomer, 0.0 100 parts by weight (solid content) of a copolymer latex obtained by emulsion polymerization in the presence of 1 to 200 parts by weight of starch, and 0.001 to 20 parts by weight of a preservative composed of a compound containing a nitrogen atom and a sulfur atom. It is characterized by including and. |
