AQUEOUS COMPOSITE PARTICLE DISPERSION

摘要

Disclosed is an aqueous dispersion of composite particles comprising an aqueous medium including water and the composite particles dispersed in the aqueous medium. The composite particle has a particle (A) and a polymer layer (B) with which at least a part of a surface of the particle (A) is encapsulated. The particle (A) is at least any one particle of an inorganic solid particle, or a silica- encapsulated particle having a core particle and a silica layer with which at least a part of the surface of the core particle is encapsulated. The zeta potential of the composite particles in the aqueous dispersion of composite particles at 60°C is -70 mV to -160 mV at any pH in the range from 7 to 11.
