<P>PROBLEM TO BE SOLVED: To provide a method for producing a copolymer latex which is excellent in storage stability, in which substantially no distribution of solid concentration is produced even when stored in low-temperature environment for a long period of time but a homogeneous state is retained. <P>SOLUTION: In the method for producing the copolymer latex, a monomer mixture composed of (a) 20-80 mass% of a conjugate diene-based monomer, (b) 0.5-7 mass% of an ethylenically unsaturated carboxylic acid monomer, and (c) 13-79.5 mass% of another copolymerizable monomer (where (a)+(b)+(c)=100 mass%) is emulsion-polymerized by using 0.01-10 pts.mass of a component (α) (formula) and/or a component (β) (two OH groups in formula are substituted by two OCOCH<SB POS="POST">3</SB>groups). <P>COPYRIGHT: (C)2012,JPO&INPIT |
