Abstract

L'invention concerne une poudre d'agent de virage fixable par pression comprenant des particules qui contiennent du polyéthylène, un colorant et, facultativement, des additifs. Selon l'invention le polyéthylène a une moyenne en poids de poids moléculaire d'au moins 1 500, une cristallinité d'au moins 75 % et une densité d'au moins 0,93. L'invention est applicable, notamment, aux poudres d'agent de virage utilisées dans les procédés de développement à brosse magnétique et à bain de poudre.
