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. |

1. An aqueous dispersion of composite particles comprising:
an aqueous medium including water; and composite particles dispersed in the aqueous medium, wherein the composite particles has a particle (A), and a polymer layer (B) encapsulating at least a part of a surface of the particle (A); 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 encapsulating at least a part of a surface of the core particle; and a 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. |
