摘要： PROBLEM TO BE SOLVED: To provide a photosensitive material capable of releasing a large quantity of a photographic useful material under the condition of a small quantity of a reducing agent with an amplification reaction at the time of using a positively active parent nucleus and excellent in discrimination by incorporating a specific image forming compound. SOLUTION: The image forming material expressed by the formula is used. In the formula, Y represents a group to be reduced, which has a property of generating RED-L1 -(PUG)k reversely corresponding to the reaction of a photosensitive silver salt having an image like latent image, T represents a simple bond or a connecting group cleaved reversely corresponding to the development, RED represents a group having no reducing property until T-RED bond is cleaved and the group capable of reducing Y, L1 represents a simple bond or a connecting group, PUG represents a photographic useful compound and (k) represents integers of 1-3. As a result, the photosensitive material capable of causing the amplification reaction and excellent in discrimination is obtained.

摘要： PURPOSE:To obtain the titled material having a stabilization of the photosensitive material during a storage and capable of releasing a photographic reagent with a necessary timing in the developing treatment by incorporating a precursor of a specific photographic reagent to the titled material. CONSTITUTION:One or more kinds of the precursor of the photographic reagent shown by formula wherein Z is 5.7 membered ring forming non-metallic atoms, R1-R3 are each a hydrogen atom or a substituent, (m) is 0-3, (n) is 0 or 1, (m+n) is 1-3, X is an electrophilic binding, L is a timing group, (l) is 0 or 1, PUG is a photographically usable group is incorporated to the silver halide (AgX) photographic sensitive material. Said AgX photographic sensitive material is stable under a storage condition and may release the photographic reagent rapidly and with a good efficiency of releasing the blocking group and with a timing necessary to the reagent during the treatment. Especially, the titled photosensitive material may release the photographic reagent with a good timing, even if the treatment is effected under a relatively low pH condition of 9-12. The titled material capable of preventing the reduction of the sensitivity and capable of displaying the function of the released photographic reagent sufficiently is obtd. by adding the precursor of said reagent shown by the formula to the titled material.

摘要： PURPOSE: To add a photographic reagent stable in storage but releasable at a necessary timing at the time of processing and capable of functioning at a wide range of pH by incorporating the specified blocked photographic reagent.
CONSTITUTION: The incorporated blocked photographic reagent is represented by the formula in which A is the photographic reagent or its precursor combined through a hetero atom; each of R
1 WR
3 is H or a substituent; Z is an atomic group necessary for forming a carbon ring or hetero ring except one having -NH- at the adjacent position of the C atom substd. by R
1 . Such a photographic reagent precursor may be added to any layer so long as it is arranged so as to effectively function on the development of a silver halide emulsion. The use of the blocked reagent permits the reagent to be stable during storage and to be released at the necessary timing. When the reagent moiety of the reagent precursor is, e.g., a fog or development inhibitor, the gradation of a dotted image can be lengthened. The blocked reagent or its precursor can be widely used for each of color and black-and-white photosensitive material.
