Document Type and Number:
Japanese Patent JP7180628
Kind Code:
B2
Abstract:
The invention relates to a tackifying resin emulsion, an aqueous adhesive and/or adhesive composition, and an adhesive and/or adhesive sheet. Provided is a tackifying resin emulsion which is capable of providing an aqueous adhesive and/or adhesive composition that has excellent curved surface adhesion to a polyolefin resin while maintaining adhesion to various substrates and retention to an adhesive and/or adhesive layer, and which has excellent compatibility with a base polymer. The tackifying resin emulsion comprises a rosin resin (A) having a softening point of 120-180 DEG C, a petroleum resin (B) having a ratio (S'NMR/SNMR) of 6.3-7.6 ppm of a peak area value (S'NMR) to a total peak area value (SNMR) in a 1H-NMR spectrum of 0-4.0%, and an emulsifier (C).
