Abstract
PROCEDIMIENTO PARA PREPARAR PIGMENTOS MAGNETICOS COLOREADOS. COMPRENDE: UNA ETAPA REDUCCION, Y EN CASO DADO, LA OXIDACION DE A-FE2O3 EN FORMA DE PLAQUETAS O DE ESCAMAS, PARA DAR FE3O4 O BIEN G-FE2O3; UNA SEGUNDA ETAPA EN LA QUE SE COMBINA EL PIGMENTO MAGNETICO CON UN AGENTE COLORANTE DE ALTO PODER TINTOREO Y QUE CONTIENE UN PIGMENTO BLANCO CON ALTO PODER DE DISPERSION, DE TAL MODO QUE NO SE PRODUZCAN DETERIOROS DE LAS PARTICULAS INDIVIDUALES, ES DECIR, BAJO ESFUERZO CORTANTE; Y UNA TERCERA ETAPA DONDE SE ELABORA LA COMBINACION OBTENIDA EN LA SEGUNDA ETAPA, CON ADICION DE AGLUTINANTES; SIENDO EL DIAMETRO DE LAS PLAQUETAS O ESCAMAS DE 0,5 A 25 MICRAS. TIENE APLICACIONES EN LA TECNICA DE REPRODUCCION DE FOTOGRAFIAS EN COLOR.
