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.
Claims2
A process for forming a filter photographic material, comprising the steps of:
- a) creating a first laminent including the substeps of (a1) laminating a release layer onto a carrier film, (a2) laminating a filter layer onto said release layer, and (a3) laminating an adhesive onto said filter layer;
- b) creating a second laminent, including the substeps of (b1) laminating an electrode onto a transparent support, and (b2) laminating a photoconductive layer onto said electrode;
- c) laminating said first laminent and said second laminent together, utilizing said adhesive layer of said first laminate;
- and d) removing said carrier film.
