Abstract

PURPOSE:To regulate the release timing of a photographically useful group by converting the bonding part of the group into a specified timing group. CONSTITUTION:To a sensitive material is added a compound represented by the general formula (where A is component capable of reacting with the oxidant of a color developing agent, PUG is photographically useful group, Y is a nucleophilic precursor, it may form a ring together with X, Z is an electrophilic group, and X is a group relating Y to Z in three dimensions, connects to A at a position where it can be substituted for the oxidant of the color developing agent, and can release PUG through intramolecular nucleophilic substitution reaction accompanied by ring closure between Z and Y converted into a nucleophilic group after breaking the bond between A and X). By separating the coupler and the nucleophilic group in the timing group and making the nucleophilic group its precursor, the decomposition due to a processing soln. is improved, and the time up to release can be changed considerably.
