Abstract
A process for producing a resin dispersion characterized in that an ethylenically unsaturated monomer capable of forming a polymer insoluble in an aqueous medium is polymerized in a solution formed by dissolving in said aqueous medium a water-soluble polymer derived from PA1 (1) 10-90% by weight of a hydroxyalkyl (meth-)acrylate expressed by the following general formula ##STR1## wherein R is a hydrogen atom or a methyl group, and l is an integer of 2, 3 or 4, PA1 (2) 10-90% by weight of a polyalkyleneglycol mono (meth-)acrylate expressed by the following general formula ##STR2## wherein R is a hydrogen atom or a methyl group, m is an integer of 2 or 3, and n is an integer of 2 to 20, and PA1 (3) 0-30% by weight of another ethylenically unsaturated monomer.
