| titleOfInvention | Silver halide photographic sensitive material and ultra-high contrast image forming method by using this material |
| abstract | PURPOSE: To obtain photographic characteristics of an ultra-high contrast and high sensitivity by incorporating a specific hydrazine deriv. into the photographic sensitive material. n CONSTITUTION: The silver halide particles in silver halide emulsion layers is the silver halide contg. at least 10% silver chloride in which a part or the whole of the silver chloride in the silver halide particles is completely uniformly distributed. The emulsion layers further contain at least one kind of the hydrazine deriv. expressed by formula I. In the formula I, R 1 denotes an aliphat. group or arom. group or heterocyclic group; R 2 denotes a hydrogen atom, alkyl group, etc.; G 1 denotes a carbonyl group, sulfonyl group, etc.; both A 1 , A 2 are a hydrogen atom or one is the hydrogen atom and the other denotes a substd. or unsubstd. alkyl sulfonyl group, etc. The silver halide photographic sensitive material of the ultra-high contrast of the gradation in excess of 10 is obtd. in this way by using the stable developing soln. n COPYRIGHT: (C)1990,JPO&Japio |
