PROBLEM TO BE SOLVED: To provide an aqueous adhesive for a flooring material, wherein the aqueous adhesive is excellent in water resistance and is attachable in relatively long time. SOLUTION: The aqueous adhesive for a flooring material includes an acrylic emulsion including an acrylic resin with a weight-average molecular weight of 200,000 or more and a tackifier. The tackifier preferably includes a rosin-based resin with a softening point of 100°C or higher. Based on 100 pts.mass of the acrylic resin, 10-100 pts.mass of the rosin-based resin is preferably included. COPYRIGHT: (C)2011,JPO&INPIT |
