PURPOSE:To obtain the high image quality and the high contrast of a picture by incorporating a specified amount of silver chloride and a ruthenium salt respectively, and at least one kind of specified comds. in the photosensitive material. CONSTITUTION:The photosensitive material contains at least 60mol% of silver chloride and the ruthenium salt in an amount of 1X10<-9>-1.0X10<-5>mol per 1mol of silver halide. At least one kind of the compds. shown by the formula R1 NHNHCOR2 is incorporated in the photosensitive material. In the formula, R1 is aryl or pyridyl group which may be substd., R2 is hydrogen atom or phenyl or 1-25C alkyl group which may be substd. Thus, the picture having the high image quality and the high contrast as the reverse photosensitive material for a daylight room, is obtd. |
