Abstract

Procedimiento de producir pigmentos de ftalocianina metálica, finamente divididos, fuertes desde el punto de vista tintóreo, virtualmente libres de halógeno, estables al ácido sulfúrico, que, en contacto prolongado con líquidos orgánicos capaces de producir crecimiento de cristales con pigmentos de ftalocianina empastada con ácido tendrán un tamaño medio de partículas de manos de 2 micras, carcterizado porque se somete al pigmento a trituración con un ácido triturador sólido en presencia de suficiente líquido orgánico cristalizante para mantener un magma denso, y mantener la trituración hasta que el pigmento se transforma en forma finamente dividida y estable a los disolventes, con un tamaño medio de partículas por debajo de 2 micras, y la mayoría por debajo de una micra.
