Title:
COPOLYMER LATEX FOR MOISTURE-PROOF PAPER, COATING COMPOSITION FOR MOISTURE-PROOF PAPER AND MOISTURE-PROOF COATED PAPER
Document Type and Number:
Japanese Patent JP2003342897
Kind Code:
A
Abstract:

To provide a copolymer latex for moisture-proof paper giving moisture-proof paper excellent in balance between moisture-proofness and easily defibrating property, and also in anti-blocking property, and to obtain a coating composition for moisture-proof paper containing the latex, and moisture-proof coated paper obtained by coating the coating composition.

The copolymer latex for moisture-proof paper is obtained by polymerizing a monomer mixture containing a relatively small amount of an ethylenic unsaturated acid monomer in the presence of a copolymer latex obtained by polymerizing a monomer mixture containing a relatively large amount of an ethylenic unsaturated acid monomer, in the polymerization of a monomer mixture having a specific composition containing an aliphatic conjugated diene monomer, an aromatic vinyl monomer, an ethylenic unsaturated acid monomer and other ethylenic unsaturated monomers copolymerizable with these monomers.
