Patent ID: 7862896

Claim:
Core-shell type resin particles (C2) each comprising a film shell layer (P) in one or more layer structure made of a first resin (a) and a core layer (Q) in one layer structure made of a second resin (b), wherein the weight ratio of the film shell layer (P) and the core layer (Q) is in a range of (0.1:99.9) to (70:30), the content of volatile components of the resin particles (C2) is 2% by weight or lower, and the resin (a) has an initial softening temperature of 40 to 270Â° C., a glass transition temperature of 20 to 100Â° C., a flow temperature 60 to 220Â° C., and the difference of the glass transition temperature and the flow temperature in a range of 0 to 120Â° C.
