摘要： Photographic compound (A) capable of releasing a photographically useful group is represented by the formula: SOL-CAR-LINK-PUG wherein SOL is a water-solubilizing group; CAR is a carrier moiety that, upon reaction with oxidized developing agent, is capable of releasing LINK-PUG and capable of forming a compound that is washed out of the photographic element during photographic processing; LINK-PUG is in turn capable of releasing a photographically useful group (PUG) during photographic processing and LINK-PUG is represented by the formula: ##STR1## wherein X, R.sub.1, R.sub.2, R.sub.3, R.sub.4 and PUG are as defined in the application. The photographic compound (A) enables formation of easily removable compounds in photographic elements and processes that provide images having improved acutance.
