Summary:PROBLEM TO BE SOLVED: To provide a synthetic resin emulsion adhesive satisfying at least one requirement among (1) excellent water-resistance, hot water resistance and boiling water resistance, (2) high final adhesive strength and (3) small temperature dependency of the viscosity to cause little viscosity increase even at a low temperature to prevent the gelatinization and keep excellent low- temperature workability. SOLUTION: Vinyl aetate and/or a (meth)acroic acid ester are polymerized by using (a) an ethylene-modified PVA as a protective colloid. In the above process, (b) a (co)polymer of a carboxy-containing polymerizable unsaturated monomer and/or (c) an amide-modified PVA are used also as the protective colloid or, in addition to the above, an ethylene-vinyl acetate copolymer emulsion is used as a seed to perform a seed polymerization.
