Bleach-accelerating compositions and use thereof in photographic color processing. |
摘要 |
<p>Improved bleach-accelerating compositions that are especially useful in the reversal color processing of photographic elements are comprised of a bleach-accelerating agent and an ethyleneoxy-substituted fatty acid ester of sorbitan. The bleach-accelerating composition is utilized subsequent to the color developing step and prior to the bleaching step and serves to enhance the effectiveness of the bleaching step. Incorporation of the ethyleneoxy-substituted fatty acid ester of sorbitan in the bleach-accelerating composition serves to avoid or at least minimize problems of scum formation which commonly occur in such compositions.</p> |
