POLYMERIC RESIN, AND ITS PRODUCTION AND USE

摘要

The invention relates to an aqueous emulsion comprising a polymeric resin and prepared by polymerizing (a) at least one amino acid of either one of the formula: (Ia) and of the formula: (Ib) with (b) at least one other polymerizable monomer, in an aqueous medium, the component (a) and at least a portion of the component (b) being introduced separately into the reaction system. The resulting emulsion is stable in the absence of surfactants, which means that the problems associated with the use of surfactants can be entirely avoided.
