INTERNAL LATENT IMAGE SILVER HALIDE PHOTOGRAPHIC EMULSION |
摘要 |
Direct positive photographic elements are disclosed employing internal latent image silver halide emulsions associated with developer autoxidation promoter agents constituted by 5 or 6 membered nucleus-containing heterocyclic compounds comprising an azomethine group, whose methine group is substituted with a 5-amino-1,2,4-triazolyl group, and/or copper complex compounds thereof. Preferably said direct positive photographic elements are multi-layer elements comprising internal latent image type type silver halide emulsion layers sensitized to different regions of the visible light and associated with image-dye providing compounds (photographic color couplers). |
