RESIN DISPERSION AND RESIN PARTICLE

摘要

Disclosed are core-shell resin particles (C2) each comprising one or more film-like shell layers (P) comprising a first resin (a) and a core layer (Q) comprising a second 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 resin (a) has an initial softening temperature of 40 to 270°C, a Tg of 20 to 250°C, a flow temperature of 60 to 300°C, and the difference of the Tg and the flow temperature in a range of 0 to 120°C. Said resin particles are excellent in electrostatic property, thermal storage stability and thermal properties, and exhibit a narrow particle diameter distribution.
