Abstract

Procédé de préparation de produits pulvérulents, faciles à disperser dans les milieux organiques, à base de colorants sublimables entre 100 et 230 degrés C. On sèche de manière connue en soi les dispersions aqueuses de ces colorants dont les particules sont revêtues en surface de composés répondant à la formule R - Z dans laquelle R est un radical hydrophobe à au moins 5 atomes de carbone et Z représente un groupe -OH, -COOH, -NH2 , -O(C2 -H4 O)n H, -NX1 X 2 ou -NH(CH2 )m NX1 X2 , n étant égal à 0, 1 ou 2, m = 2 à 6 et X1 et X2 = H ou alkyle en C1 -C4 et, avant ou après séchage, on mélange avec des résines fondant à plus de 70 degrés C, en procédant éventuellement à une fragmentation grossière. Les produits obtenus conviennent remarquablement à l'impression par transfert.
