Photographic material and process comprising a thiol beach assist in the low sensitivity layer of a triple-coat |
摘要 |
A photographic element comprises at least three light sensitive silver halide layers spectrally sensitized to the same region of the electromagnetic spectrum wherein the least sensitive such layer, or a nonsensitive layer adjacent thereto, comprises a compound which contains a releasable thiol fragment or a precursor thereof wherein: A. the amount of the thiol-containing compound or precursor contained in such layers is both sufficient to increase the extent of silver bleaching during bleaching and is greater than the amount contained in any of the more sensitive layers of the same sensitivity; and B. the thiol fragment contains a sulfur atom which is not directly bonded to an aromatic atom and contains a water-solubilizing group.
