Abstract
A filter photographic material is produced by laminating together, in opposite relation, a first laminate obtained by laminating a filter layer and an adhesive layer successively on a support and a second laminate obtained by laminating a photoconductive layer and a transparent electrode layer successively on a carrier film through a release layer, followed by removal of the carrier film. Thus, it is possible to prevent the discoloration, fading, etc. of the filter layer and its preparation is made more efficient.
