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 CaCl, 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 CaCl, when the solids concentration of the latex is 20% by weight, is defined as CS(B) (% by weight).
