Title:
ADHESIVE FOR VINYL CHLORIDE-BASED RESIN
Document Type and Number:
Japanese Patent JP3675975
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain an adhesive for a vinyl chloride-based resin, excellent in peel strength, tensile shear force, initial adhesive strength, etc., further plasticizer resistance to a plasticizer contained in a substrate made of the vinyl chloride- based resin and compatibility, etc., with the vinyl chloride-based resin and having well balanced bonding characteristics by controlling the gel content of a copolymer to a prescribed value or below even when using acrylonitrile.
SOLUTION: This adhesive for a vinyl chloride-based resin comprises a copolymer latex, obtained by carrying out the emulsion copolymerization of a monomer mixture comprising ≥25 and ≤45wt.% acrylonitrile, ≥45 and ≤74wt.% conjugated diene-based monomer, ≥1 and ≤10wt.% ethylenically unsaturated carboxylic acid monomer and ≤20wt.% other monomers copolymerizable therewith (100wt.% sum total) and having ≥100,000 and ≤500,000 number-average molecular weight and ≤50wt.% get content, and a tackifier.
