Preparing and reproducing filters and preparing materials for photographic filters.

PREPARE A filter comprises illuminating a photographic material and a mask at a distance GIVEN THE SAME WITH LIGHT ISSUED FROM OPPOSITE DIRECTIONS TO MAKE A HOLOGRAM AND THEN PLAY AN IMAGE REPRODUCED HOLOGRAM IN THE MATERIAL PHOTOGRAPHIC, thereby making it possible FORM PREPARING ACCURATE a color filter without any close contact mASK WITH PHOTOGRAPHIC MATERIAL AND without causing the mask image darkens. ACCORDING TO REPRODUCTION OF A HOLOGRAM APPLICABLE as a color filter, a hologram master having RECORDED BANDS RED, GREEN AND BLUE STANDS AT OPPOSITION TO A PHOTOGRAPHIC MATERIAL and then illuminated with light obtained by mixing the three colors from pHOTOGRAPHIC MATERIAL, thus making it possible to reproduce the image REPRODUCED IN pHOTOGRAPHIC MATERIAL IN A SINGLE OPERATION EXPOSURE, while dispenses a step photolithography, alignment or precise registration, ETC. The process for making a filter material PHOTOGRAPHIC includes rolling in opposed relation, a first laminate obtained by laminating on A filter layer and an adhesive layer on a support and a second laminate obtained by laminating a CAPA PHOTOCONDUCTOR and an electrode layer TRANSPARENT FILM FORTH ON A cARRIER THROUGH A release layer, followed by removal FILM cARRIER, thus making it possible prevent discoloration, fading, etc. of the filter layer and making its efficient preparation.
