A process for emulsion-polymerizing unsaturated monomer(s) is disclosed. When a hydrazine derivative having at least two hydrazine residues per molecule is added to the polymer dispersion obtained by said emulsion polymerization process, a polymer dispersion composition capable of forming a film which is excellent in blocking resistance, adhesiveness to an alkyd resin film, water-resistant adhesiveness to an alkyd resin film and water-resistant anti-whitening can be obtained.
