<p>Disclosed is a copolymer latex for an adhesive such that at least part of a first phase contains latex particles coated by a second phase. The first phase is obtained by emulsion polymerization of a first phase monomer composition that contains 10 - 45% of a butadiene monomer, 0 - 5% of a vinylpyridine monomer and 55 - 90% of a styrene monomer. The second phase is obtained by emulsion polymerization of a second phase monomer composition that contains 50 - 90% of a butadiene monomer, 10 - 30% of a vinylpyridine monomer and 0 - 40% of a styrene monomer.</p> |
