Abstract:
A highly water resistant tackifier resin emulsion comprising:a. tackifier resin particles formed from acrylic (co)polymer seed particles having on their surface polar groups derived from 2-acrylamido-2-methyl-1-propanesulfonic acid and wherein the tackifier resin particles are obtained by growing the seed particles 1.2 to 30 times by (co)polymerizing acrylic monomer(s) from the inner seed particles while at least part of a tackifying component is incorporated therein; andb. an emulsifier,wherein the emulsion includes the emulsifier in an amount of not greater than 2% by weight and the tackifying component in an amount of 40 to 160 parts by weight based on 100 parts by weight of the seed particles.
