Method for producing aqueous dispersion of hollow polymer particles, composition for paper coating, and coated paper |
| abstract |
A method includes: forming core polymer particles by copolymerizing a monomer mixture (a); forming a first shell layer substantially surrounding the particles and not swollen by a base by copolymerizing a monomer mixture (b) in the presence of the particles; swelling the particles with a base to an aqueous dispersion containing the particles on which the layer has been formed in an amount of 0.1-30 parts by weight; and swelling the layer with a monomer mixture (c) to an aqueous dispersion containing the particles on which the layer has been formed in an amount of 0.1-45 parts by weight, in which a difference in water contents represented by (a water content in the particles on which the layer has been formed after swelling the shell)−(a water content in the particles on which the layer has been formed before swelling the shell) is 1 to 45%. |
