Abstract:
A method for producing an aqueous dispersion of hollow polymer particles including: a core formation step wherein core polymer particles are formed by copolymerizing a monomer mixture; a first shell layer formation step wherein first shell layers that cover the particles are formed by copolymerizing a monomer mixture in the presence of the particles; a core swelling step wherein the particles are swelled by adding a base into an aqueous dispersion containing the particles, which have been provided with the first shell layers, and setting the pH of the aqueous dispersion to 7 or more; a polymerization stopping step wherein the polymerization is stopped after the core swelling step; and a shell swelling step wherein the first shell layers are swelled by adding a monomer mixture into the aqueous dispersion containing the particles, which have been provided with the first shell layers and swelled, after the polymerization stopping step.

Claim (Index 2):
The method for producing an aqueous dispersion of hollow polymer particles according to  claim 1 , further comprising a second shell layer formation step of, after the shell swelling step, forming a second shell layer (C) by copolymerizing the monomer mixture (c) in the presence of the aqueous dispersion containing the core polymer particles (A) on which the first shell layer (B) is formed, the core polymer particles (A) and the first shell layer (B) being swelled.
