Abstract

On améliore l'efficacité des N-acylanthranilates de chrome (III) comme substances régulatrices de la charge en faisant réagir un acide N-acylanthranilique en solution méthanolique, en présence de méthylate de sodium avec un sel de chrome (III), en dissolvant le précipité résultant dans du toluène en séparant par distillation sous vide une partie de toluène et, après filtration, en amenant la solution résultante au moyen de toluène frais à la teneur en N-acylanthranilate de chrome (III) désirée pour la dispersion. Application : au dépôt de particules de luminophore sur écrans de tubes cathodiques couleurs par voie électrophotographique.
