PROBLEM TO BE SOLVED: To obtain a pasting agent free from the troubles of aggregation, separation and precipitation in storage and having excellent storage stability by carrying out emulsion polymerization of a vinyl acetate solution produced by adding a vinyl acetate oligomer to vinyl acetate monomer. SOLUTION: An emulsion-type pasting base agent composed of a vinyl acetate polymer is produced by the emulsion polymerization of a vinyl acetate solution produced by adding a vinyl acetate oligomer to vinyl acetate monomer at a ratio of 0.01-5 ppm, preferably 0.1-3 ppm and containing a nonionic surfactant such as polyoxyethylene alkyl ether as an emulsifier in the presence of a polymerization initiator such as 2,2'-azobis(2-amidinopropane) at 40-120 deg.C and pH 3-9.
