The invention relates to a process for the production of spherical, polyester particles, wherein the particle size can be exactly adjusted in the range of 1 to 200 µm and a particle size distribution with a span (=d90-d10/d50)1.5, as well as the use of the produced particles for toner compositions in electrophotographic and direct printing systems and powder coatings.
L'invention a trait à un procédé permettant de produire des particules sphériques de polyester dont la taille peut être choisie avec précision entre 1 et 200 µm, et dont la distribution en taille se situe dans la fourchette (=d90-d10/d50)?1,5, et à l'utilisation desdites particules dans des compositions de toners destinées à des systèmes d'impression directe ou électrophotographique, et à des revêtements pulvérulents.
