Abstract (en)

[origin: EP0193389A2] Bleach accelerator releasing organic compounds which have a releasable bleach accelerator moiety represented by the moiety: -(TIME)n-S-R1-R2 wherein TIME is a timing group; n is 0 or 1; R1 is a linking group; and R2 is a water solubilizing group, are useful in dye-forming photographic elements and processes The bleach accelerator releasing compound enables improved images by means of release of the bleach accelerator moiety in the photographic element during processing.
