Title:
TACKIFIER RESIN AQUEOUS DISPERSION, AQUEOUS ADHESIVE AND ADHESIVE SHEET
Document Type and Number:
Japanese Patent JP2020023596
Kind Code:
A
Abstract:
To provide a tackifier resin aqueous dispersion that has an extremely small content of an organic solvent, and gives excellent storage stability, mechanical stability, coatability, workability, adhesiveness, curved surface adhesiveness, moist heat resistance, constant load peelability, and base material adhesion, and provide an aqueous adhesive and an adhesive sheet.SOLUTION: A tackifier resin aqueous dispersion has, based on a tackifier resin (A) with a softening point of 100-180°C of 100 pts.mass, a copolymer resin (B) of 0.5-50 pts.mass, having the organic solvent content of 1000 ppm or less, satisfying the following (1) and (2). (1) The copolymer resin (B) is obtained by modifying a copolymer (X) with a compound (b3) having an alkylene oxide unit. (2) The copolymer (X) at least has, as constituent monomers, at least one compound (b1) selected from the group consisting of α-olefin, styrene, vinyl ether, vinyl sulfide and diolefin, and a dibasic acid having an unsaturated group or an anhydride thereof (b2-1).SELECTED DRAWING: None
