PROBLEM TO BE SOLVED: To provide a tackifier resin emulsion which improves the stability of a gear pump or the like against mechanical shear. SOLUTION: This tackifier resin emulsion comprises (a) a tackifier resin, (b) an anionic polymer emulsifier, and (c) at least one selected from rosin salts, 8 to 22C alkenyl group-having alkenyl succinic anhydrides, and the salts of the 8 to 22C alkenyl group-having alkenyl succinic anhydrides. (b) The anionic polymer emulsifier is preferably the salt of a copolymer prepared by copolymerizing a styrene compound, an alkyl (meth)acrylate, and an anionic monomer. COPYRIGHT: (C)2007,JPO&INPIT
