Title:
NONAQUEOUS DISPERSION OF RESIN PARTICLES
Document Type and Number:
WIPO Patent Application WO/2011/129058
Kind Code:
A1
Abstract:
Provided is a nonaqueous dispersion of resin particles, in which the resin particles have uniform particle diameters and shapes and which exhibits excellent fixing properties, particularly when used as a liquid electrophotographic developer. More specifically, provided is a nonaqueous dispersion (X) in which resin particles (C) are dispersed in a nonhydrophilic organic solvent (L) that exhibits a relative permittivity of 1 to 4 at 20°C, said resin particles (C) being core-shell type resin particles each of which comprise a resin particle (B) that contains a resin (b) and fine particles (A) that contain a resin (a) and that either adhere to the surface of the resin particle (B) or form a film on the surface of the resin particle (B), wherein the solubility of (a) in (L) at 25°C is 10wt% or less relative to the weight of (a).
