Abstract

L'invention concerne un toner pour l'électrophotographie, avec un petit diamètre des particules, tout en étant excellent en termes d'aptitude à être fixé à basse température, de résistance au maculage à chaud et de caractéristiques d'image. L'invention concerne également un procédé servant à produire un tel toner, une dispersion liquide de particules de résine réticulée utilisée pour produire un tel toner pour l'électrophotographie et un procédé servant à produire une telle dispersion liquide de particules de résine réticulée. L'invention concerne précisément une dispersion liquide de particules de résine réticulée ayant un diamètre des particules moyen en volume (D50) de 0,05 à 0,7 µm, laquelle est obtenue par un procédé comprenant une étape (A) servant à obtenir une dispersion liquide de particules de résine en neutralisant dans un milieu aqueux une résine contenant un polyester ayant un groupe acide et une étape (B) servant à mélanger la dispersion liquide de particules de résine obtenue dans l'étape (A) avec un polymère ayant un groupe oxazoline à une température de 60 à 100 ˚C.
