Liquid developer for color electrophotography and process for preparation of the same

摘要

Liquid developer formulations adapted to colored toners suitable for trichromatic processes in electrophotography, the toners being lightfast organic dye pigments with substantially no photoconductivity which are mixed with a paraffinic material as a protective polymer (a dispersing liquid being used if the protective polymer is a solid) and suspended in an insulating hydrocarbon carrier medium together with a metal soap and a phenol derivative soluble in the carrier.
