摘要
PROBLEM TO BE SOLVED: To provide a tackifier resin emulsion for providing an adhesive composition with various preferable adhesion characteristics such as a heat resistance sustainment without lowering the compatibility with a base polymer while reducing the organic solvent content, an adhesive composition, and a tackifier resin emulsion with a high yield, a preferable storage stability and a high softening point safely in the production work without use of an organic solvent.;SOLUTION: The tackifier resin emulsion includes as the solid component except an emulsifier component 60-99 wt.% of a polymerized rosin ester resin (A) of 135-180°C softening point and 20 or less acid number, 1-40 wt.% of a liquid hydrocarbon polymer (B) having a carboxyl group or an acid anhydride group with a 5-100 acid number of other than (A) and 300-30,000 weight average molecular weight [based on the sum of the component (A) and the component (B) as 100 wt.%]. The amount of the organic solvent included in the emulsion is 50 ppm or less.;COPYRIGHT: (C)2009,JPO&INPIT
