ABSTRACT:
A compound having a carboxy group and a long-chain alkylthio group and/or a salt thereof is used as an emulsifier and, on the other hand, emulsion polymerization is carried out using a polymerizable monomer or monomers having, within their molecule, a group reactive with a carboxyl group as raw materials for emulsion polymerization, whereby the resin produced by emulsion polymerization and the emulsifier react with each other efficiently on the occasion of film formation and form a crosslinked structure. When a compound having a polymerizable unsaturated group in addition to the carboxyl group and long-chain alkylthio group and/or a salt thereof is used as the emulsifier, not only the above-mentioned crosslinked structure is formed but also the polymerizable unsaturated group in the emulsifier will react with the unsaturated group in the polymerizable monomer or monomers in the manner of grafting. As a result, the compatibility between the emulsifier and the emulsion-polymerized resin is improved.
