摘要： PROBLEM TO BE SOLVED: To obtain an adhesive free from drawbacks inherent in a vinyl acetate resin emulsion and being excellent in properties such as workability, heat resistance, water resistance, storage stability and adhesiveness by incorporating a vinyl acetate resin emulsion prepared by the seed polymerization of vinyl acetate in an emulsion of an ethylene/vinyl acetate copolymer resin having a specified ethylene content. SOLUTION: The ethylene content of the ethylene/vinyl acetate copolymer resin (EVA) in the emulsion is 15-35 wt.%. In order to keep the stability of the emulsion formed in the seed polymerization, a polyvinyl alcohol(PVA) is used. The amount of EVA uses is desirably 15-40 wt.% based on the entire resin. The content of the resin contained in the vinyl acetate resin emulsion formed by the seed polymerization is 25-65 wt.% (in terms of the solid matter). The seed polymerization is carried out by charging a reactor with water and the EVA emulsion and adding a vinyl acetate monomer while polymerizing it in the presence of a polymerization initiator.
