| titleOfInvention | Multicolor optical filter manufacturing method |
| abstract | (57) [Abstract] [Purpose] In the case of forming a black pattern by a photographic method in a multicolor optical filter used in a color image pickup tube, a color solid-state image pickup device, etc., in order to remove an alkali metal salt which is a cause of pattern formation failure. An object of the present invention is to provide a method for producing a multicolor optical filter, which uses the simple dura mater method described above. [Structure] Boric acid is allowed to act on a silver salt emulsion composed of polyvinyl alcohol and silver halide. As a result, the polyvinyl alcohol is hardened and becomes insoluble in water. By soaking it in water in this state, the alkali metal salt generated in the emulsion preparation step can be removed. As a result, defective defects of the black pattern can be significantly reduced. |
