Abstract

L'invention concerne l'industrie des matières colorantes. Elle a pour objet un procédé de préparation d'un pigment de chrome traité, suivant lequel on précipite de l'antimoine à la surface d'un pigment en présence d'une solution d'ions métaphosphate. Ce procédé est préféré pour la préparation de pigments de chrome inaltérables ayant une teneur particulièrement basse en plomb soluble qui sont recommandables pour un certain nombre d'applications où la toxicité du plomb soluble est à proscrire.
