Process for making photographic couplers capable of producing wash-out dyes |
| abstract |
(57) Abstract: The present invention is capable of producing wash-out dyes in photographic light-sensitive materials during photographic processing to form images with improved acutance, stability and inter-image effects. It relates to novel photographic couplers and photographic light-sensitive materials and processes using such couplers. A substituted or unsubstituted aryloxy, thioaryloxy, heterocyclicoxy and thioheterocyclicoxy releasing group having a phenoxy timing group containing a photographically useful group (PUG) attached thereto Provided is a method of making a wash-out photographic coupler comprising a coupler moiety (COUP) containing a ballasted releasing group (A). |
