Title:
METHOD FOR PRODUCING RESIN PARTICLES AND TONER
Document Type and Number:
WIPO Patent Application WO/2019/107087
Kind Code:
A1
Abstract:
The present invention relates to a method for producing resin particles by: obtaining resin microparticles that contain a polyester resin (a) which has a glass transition temperature (Tga) of -20 to 57˚C and which is obtained by polycondensation of an alcohol component (y) and an unsaturated carboxylic acid component (z); and then aggregating and fusing the resin micro particles. The method for producing resin particles comprises a step of producing a modified resin by cross linking the carbon-carbon double bonds derived from the unsaturated carboxylic acid component (z) of the polyester resin (a) after the resin microparticles have been obtained.
