RESIN DISPERSION AND RESIN PARTICLE

摘要

Disclosed are core-shell resin particles (C2) each composed of one or more film-like shell layers (P) made of a resin (a) which is specifically a polyurethane resin and a core layer (Q) made of a resin (b). A core-shell resin particle (C2) is characterized in that the weight ratio between (P) and (Q) is from 0.1:99.9 to 70:30, the volatile content in the resin particle (C2) is not more than 2 weight%, and the content of vinyl resins in the resin (b) is not more than 30 weight%. Such resin particles have a uniform particle diameter and are excellent in electrostatic characteristics, heat and storage stability, and thermal characteristics.
