摘要： PURPOSE:To obtain chemical stability and to enable a photographically useful group to be released at a desirable speed by using a compd. represented by the formula shown here. CONSTITUTION:In the formula, as a group represented by PUG, a development inhibitor, a development accelerator, a fogging agent, a dye, a developing agent, a coupler, a silver removal accelerator, a silver halide solvent, a competitive compd., a silver removal inhibitor, etc., are enumerated. The speed of photographic action can be controlled by selecting a group of N, L, or Z in the formula, and the photographic action of PUG can be controlled to a desirable property in accordance with the object. when A is a coupler residue, it is generally called a DIR coupler, and this DIR coupler can effectively control the action range of the inhibitor, and yet it has sufficient stability. As a result, the obtained color photographic image is good in graininess, color reproducibility due to the interlayer effect, and sharpness.

摘要： PURPOSE:To obtain a photosensitive material having superior shelf stability, little fog and superior graininess by using a specified compound having chemical stability and capable of forming a photographically useful group at a desired speed. CONSTITUTION:In a reaction by which PUG is released from a compound represented by formula 1 in the presence of alkali, the formation of PUG is nearly negligible in an equilibrium state in which the reverse reaction takes place easily. The PUG rebonding reaction proceeds more slowly during development than during storage, and the concn. of PUG is relatively increased, so enough photographically useful groups are released during development at a speed depending on the properties of A, X, R1 and R2 in the formula 1. The photographically useful group PUG is a development retarder, a development accelerator, a dye or other compound selected according to the purpose.

摘要： 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.
