PURPOSE:To obtain an image which has the high max. color density and the low min. color density and the low rereversal negative sensitivity by incorporating a specified compd. and a colloidal silver in a photosensitive material. CONSTITUTION:At least one kind of the compd. shown by formula I and the colloidal silver are incorporated in the photosensitive material. In formula I, Z is an atomic group necessary for forming a 5 or 6 membered nitrogen contg. heterocyclic ring, D and D' are each an atomic group necessary for forming an acidic nucleus, R1 is a substd. or an unsubstd. alkyl group, L<1>-L<6> are each a substd. or an unsubstd. methine group, (n<1>) and (n<2>) are each 0 or 1, (l) is an integer of 0-3. Thus, the high max. color density and the low min. color density of the photographic sensitive material are obtd., and the high max. optical density of said material is obtd. even in case of runing-processing said material and preserving said material under a severe condition, and the generation of a rereversal negative image can be lessened. |
