Abstract

Un pigmento orgánico de agregación en emulsión que incluye una resina amorfa y una resina cristalina, donde el pigmento orgánico tiene un índice de ácido de aproximadamente 16 mg/eq. de KOH hasta aproximadamente 40 mg/eq de KOH y una relación de sensibilidad a la humedad relativa de aproximadamente 1 hasta aproximadamente 2, y donde la resina cristalina tiene un punto de fusión de al menos aproximadamente 60ºC. El proceso para formar las partículas incluye generar una emulsión de una resina de poliéster que tiene un índice de ácido de aproximadamente 16 mg/eq de KOH hasta aproximadamente 40 mg/eq de KOH y generar partículas agregadas de la emulsión. La capacidad de mantenimiento de la carga y resistividad incrementadas del pigmento orgánico resultante, generan por lo tanto una calidad de impresión alta y un brillo alto, y proporcionan una carga xerográfica estable en todos los ambientes.
