METHOD FOR PRODUCING COLORANT-CONTAINING RESIN EMULSIFIED PARTICLES

摘要

PROBLEM TO BE SOLVED: To provide a method for producing colorant-containing resin emulsified particles used for electrophotographic toners and excellent in colorant dispersibility in high productivity. SOLUTION: This method for producing the colorant-containing resin emulsified particles is characterized by having a process for mixing and emulsifying a binding resin such as a polyester comprising a bisphenol A alkylene oxide adduct and terephthalic acid and a water-containing colorant such as dimethylquinacridone slurry-like pigment and having a water content of 50 to 90 wt.% in the presence of a surfactant in an aqueous solvent.
