A photographic element is described which contains a ballasted, bifunctional benzisoxazolone compound of the formula:
wherein:
R is alkyl or aryl;
DEV is a silver halide developing agent;
Ball is at least one organic ballasting radical of such molecular size and configuration as to render the compound nondiffusible in the photographic element during development in an alkaline processing composition; and
n is a positive integer of 1 to 3.
The compound may be employed in a negative-working, color image transfer element to release the developer upon processing. The remainder of the compound functions to scavenge oxidized developer.
描述了一种感光元件,它含有一种压载的双功能苯并
异噁唑酮化合物,其式如下: 其中:R 是烷基或芳基;DEV 是卤化
银显影剂;Ball 是至少一个有机压载基,其分子大小和构型使该化合物在碱性冲洗组合物中显影时在感光元件中无法扩散;n 是 1 到 3 的正整数。 该化合物可用于底片工作的彩色图像传输元件中,以便在冲洗时释放显影剂。 该化合物的其余部分具有清除氧化显影剂的功能。
