Abstract

Procedimiento para la preparación de un polvo virador fijable por calor, para revelar imágenes electrostáticas latentes, que comprende principalmente partículas de virador finamente dividido que contienen constituyentes colorantes, si se desea un regulador de carga y material termoplástico, caracterizado porque antes o durante la mezcla con los otros ingredienes se fabrica todo o la mayor parte del material termoplástico, ya sea modificando los grupos epoxídicos de una resina epoxídica con una masa molar epoxídica de aproximadamente 700 como máximo, en proporción de aproximadamente 25-95% por bloqueo de dichos grupos epoxídicos haciéndolos reaccionar con un ácido carboxílico.
