Title:
METHOD OF PRODUCTION AND DUPLICATION OF FILTER, AND METHOD OF PRODUCTION OF PHOTOSENSITIVE MEMBER PROVIDED WITH THE FILTER
Document Type and Number:
WIPO Patent Application WO/1990/010881
Kind Code:
A1
Abstract:
The filter production method comprises forming a hologram by irradiating a photosensitive material and a mask spaced apart from each other at a given distance with the rays of light from opposite sides respectively, and reproducing the image of this hologram in the photosensitive material. This method does not require contact between the mask and the photosensitive material, prevents the image from being out of focus and can produce a precision color filter. A hologram applicable as the color filter is duplicated by disposing a master hologram on which R, G and B stripes are recorded and a photosensitive material in such a manner as to oppose each other and applying three-colored mixed rays of light from the photosensitive material side. This method can duplicate the reproduction image on the photosensitive material in one exposure and can eliminate the necessity for a photolithographic process, precise registering and the like. A photosensitive member provided with a filter is produced by laminating a first laminate member, which is formed by laminating sequentially a filter layer and an adhesive layer on a support, and a second laminate member formed by laminating a photoconductive layer and a transparent electrode layer on a carrier film through a peeling layer, in such a manner as to oppose each other, and then peeling off the carrier film. This method can avoid discoloration, fading, etc., of the filter layer due to heating, and can improve the production efficiency.
