Abstract

An aqueous dispersion having good stability and fluidity, and a process for production thereof. The aqueous dispersion is produced by polymerizing (a) a specified amount of an ethylenically unsaturated monomer capable of forming a water-soluble polymer in (b) a specified amount of an aqueous solution containing a water-soluble polymer while adjusting the weight ratio of (a) to (b) to from 1:5 to 5:1.
