TACKIFIER RESIN EMULSION, ACRYLIC EMULSION TYPE SELF-ADHESIVE COMPOSITION, ACRYLIC EMULSION TYPE SELF-ADHESIVE COMPOSITION FOR FOAM SUBSTRATE, AND ACRYLIC EMULSION TYPE SELF-ADHESIVE COMPOSITION FOR POLYURETHANE FOAM

摘要

PROBLEM TO BE SOLVED: To provide a tackifier resin emulsion which imparts excellent adhesive force even in a hot environment and can impart good adhesive force to a rough surface such as polyurethane foam, and an aqueous self-adhesive having excellent adhesive force in a hot environment and also having good adhesive force even to a rough surface such as polyurethane foam.;SOLUTION: The tackifier resin emulsion is obtained by emulsifying a rosin phenolic resin (A) having a softening point of 155-180°C, a weight-average molecular weight (Mw) to number-average molecular weight (Mn) ratio of 1.4-2.1, and a total of hydroxyl and acid values in a range of 50-130 mgKOH/g, wherein a content of a component whose weight-average molecular weight (Mw) is ≤260 is ≤1.5 wt.%.;COPYRIGHT: (C)2010,JPO&INPIT
