Abstract

Procedimiento para la preparación de pigmentos de quinacridona en forma finamente dispersada, caracterizado porque el pigmento bruto es triturado con un disolvente orgánico durante tanto tiempo hasta que es obtenida la finura de pigmento deseada y porque entonces es eliminado el disolvente hasta el logro de una consistencia pulverulenta del pigmento.
