Dry, coated pigment particles are obtained by first suspending uncoated pigment particles in an appropriate medium and then coating the particles while in suspension, with a polymer that is at or above the softening point for that polymer. Coating of the pigment particles is achieved by allowing the suspension to cool to a temperature below the solidification temperature for the polymer. The coated pigment particles are then recovered.

Les particules pigmentées sèches et enrobées faisant l'objet de l'invention sont obtenues d'abord par la suspension de particules pigmentées non enrobées dans un milieu appropriè, puis par l'enrobage des particules encore en suspension, cet enrobage se faisant à l'aide d'un polymère dont la température est égale ou supérieure au point de ramollissement propre à ce polymère. Pour effectuer l'enrobage des particules pigmentées, on laisse la suspension se refroidir à une température inférieure à la température de solidification propre à ce polymère. Les particules pigmentées ainsi enrobées sont ensuite récupérées.
