Abstract

Esta invencion se relaciona con un proceso mejorado para preparar pigmentos de ftalocianina metálicos que comprende: (a) calentar a una temperatura de aproximadamente 150 degree C hasta aproximadamente 200 degree C una mezcla que comprende: (i) un material formador de ftalocianinas basado en ácido ftálico (ii) por lo menos de aproximadamente 25 por ciento en mol respecto al material formador de ftalocianina (i), de un donador de metal, (iii) por lo menos alrededor de 100 por ciento en mol, relativo al material formador de ftalocianina 8i) de aproximadamente 1 al 20 por ciento en peso relativo al material formador de ftalocianina (i), de un catalizador, y (v) aproximadamente del 250 al 400 por ciento en peso respecto al material formador de ftalocianina (i), de un solvente de ftalato de di(C1-C3 alquilo), y (b) aislar el pigmento de ftalocianina metálico.
