PURPOSE:To provide a sufficient dye density to the photosensitive material even if said material is subjected to a development processing with a processing liquid which does not contain benzyl alcohol and to prevent the generation of coloring stains by incorporating specific 5-pyrazolone couplers and specific compds. into the photosensitive material. CONSTITUTION:The title photosensitive material contains the 5-pyrazolone couplers having the elimination group expressed by the formula I in the coupling position and >=1 kinds of the compds. expressed by the formulas II-IV acting as coloration stain preventive agents. In the formula I, L1, L2 denote methylene, ethylene; m, n denote 0, 1; Y denotes aryl, heterocycle, etc.; R6 denotes H, alkyl, etc.; X denotes an atom group necessary for forming a prescribed ring. In the formulas II-IV, R1, R3 denote an aliphat., arom. group, etc.; X denotes a group which is eliminated by reacting with an arom. amine developing agent; A denotes a group which forms chemical bond by reacting with an above- mentioned developing agent; n denotes 1, 0; B denotes H, aliphat. group, etc.; Y denotes a group which accelerates the addition of a developing agent; R denotes an aliphat., arom. group, etc.; Z denotes a nucleophilic group, etc. |
