Abstract
A copolymer latex for adhesives contains a copolymer latex obtained by copolymerizing an aliphatic conjugated diene monomer with another monomer copolymerizable with this, an alkali metal salt of a carboxylic acid, and a divalent metal carbonate.
Claims10
A copolymer latex for adhesives comprising:
- a copolymer latex obtained by copolymerizing an aliphatic conjugated diene monomer with another monomer copolymerizable with this,
- an alkali metal salt of a carboxylic acid, and
- a divalent metal carbonate, wherein
- the alkali metal salt of the carboxylic acid is an alkali metal salt of a rosin acid and/or an alkali metal salt of a fatty acid having a C12 to C18 alkyl group, and
- the divalent metal carbonate is blended at a proportion of 0.05 parts by mass or more and 30 parts by mass or less with respect to 100 parts by mass of the alkali metal salt of the carboxylic acid.
