Abstract

Método para preparar un revelador mejorado para empleo en copiado electrostático, que comprende una mezcla de partículas de virador y perlas de soporte revestidas con una composición de resina, caracterizado porque se hace uso de un sistema de resina que comprende politetrafluoroetileno, polietilenpropilenofluorado, y poli(amida -imida), que es estable hasta al menos 316ºC, triboeléctricamente negativo, no desconchable, esencialmente no desgastable, dispersable con respecto a los otros componentes de la resina y esencialmente no desmenuzable
