ABSTRACT:
A process for forming a color filter, which comprises patternwise exposing a black-and-white silver halide emulsion layer of a photographic material comprising a support having thereon at least one black-and-white silver halide emulsion layer, developing the photographic material with a developing solution containing a color dye developer to form a pattern containing a color dye for a pattern containing at least one dye, and removing remaining silver and/or silver halide. The patternwise exposure and color coupler containing development steps can be repeated using different color couplers to produce patterns with additional color dyes.
