ABSTRACT:
A process for producing color filters, which comprises dispersing or dissolving pigments and the like having spectral properties in three primary colors, and a structure reinforcing resin in an aqueous medium, in the presence of a surfactant comprising a ferrocene compound, to prepare micelle solutions of dispersions in each color, and dipping the patterned electroconductive transparent substrate to be subjected to electrolytic treatment in each color, and thus forming a color-separated filter on the substrate. The color filter produced according to the above process can be utilized for display elements of filters, such as liquid crystal display devices, electrochromic display devices, latitude display devices, plasma display panels, spectroscopic devices, solid-state photographic devices and dimmers.
