PURPOSE:To improve the sensitivity and to reduce the generation of the fog of the titled material, and to enable to handling the titled material under a yellow colored safety light by using a specific silver chloride bromide or silver chloride iodide bromide to a silver halide contd. in a layer of the silver halide emulsion layers, and by incorporation a compd. selected from specific compds. to the photosensitive material. CONSTITUTION:The silver chloride bromide or the silver chloride iodide bromide contg. 50mol% a silver chloride and having <=20 a mono-disperse degree and 0.05-0.5mum a mean particles size is incorporated to the silver halide contd. in a layer of the silver halide emulsion layers. The photosensitive material comprises a compd. selected from the compds. shown by formula (I). In formula (I), Z is a 5 or 6 membered heterocyclic ring, Q is a non-atomic group necessary to forming a 5 membered heterocyclic ring, R is an alkyl group, (m) is 1 or 2. In the formula (II), two groups among R1-R6 groups are an hydroxyl group, residual groups thereof are a hydrogen or a halogen atom or a sulfonic acid group, the adjacent groups among the R1-R6 groups may form a 5 or 6 membered ring of a carbon ring or a heterocyclic ring, R7 is an alkyl or an aryl group. |
