摘要： PURPOSE:To obtain a photosensitive material high in sensitivity and superior in long time storage stability and coatability by using gelatin specified in calcium content. CONSTITUTION:The silver halide photographic sensitive material contains calcium in an amount of 3,500 - 5,000ppm in the 10 - 25wt.% of the total gelatin and 200 - 400ppm calcium in the >=65wt.% of the total gelatin. It is preferred to coat the photosensitive material with the total gelatin in an amount of from the view point of long time storage stability. Hydrophilic colloids except gelatin may be used in combination as much as possible, thus permitting the obtained photosensitive material to be high in sensitivity and superior in long time storage stability and coatability.
