Abstract
A latex composition includes a latex of a conjugated diene polymer (A) having a glass transition temperature of 10° C. or less and a latex of a polymer (B) having a glass transition temperature of more than 10° C., wherein the value of (CS(B)−CS(A)) is more than 0% by weight, where a chemical stability of the latex of the conjugated diene polymer (A) to CaCl2, when the solids concentration of the latex is 20% by weight, is defined as CS(A) (% by weight), and a chemical stability of the latex of the polymer (B) to CaCl2, when the solids concentration of the latex is 20% by weight, is defined as CS(B) (% by weight).
Claims11
A latex composition comprising a latex of a conjugated diene polymer (A) having a glass transition temperature of 10° C. or less and a latex of a polymer (B) having a glass transition temperature of more than 10° C.,
- wherein the conjugated diene polymer (A) is a nitrile group-containing conjugated diene polymer,
- the polymer (B) is a homopolymer of acrylic acid ester, methacrylic acid ester, acrylic acid, or methacrylic acid,
- the conjugated diene polymer (A) and the polymer (B) are contained in a weight ratio of conjugated diene polymer (A):polymer (B) of 20:80 to 80:20, and
- the value of (CS(B)−CS(A)) is more than 0% by weight,
- where a chemical stability of the latex of the conjugated diene polymer (A) to CaCl2, when the solids concentration of the latex is 20% by weight, is defined as CS(A) (% by weight), and
- a chemical stability of the latex of the polymer (B) to CaCl2), when the solids concentration of the latex is 20% by weight, is defined as CS(B) (% by weight).
