摘要： A negative type silver halide photographic material and a process for forming a super high contrast negative image using said material are described. This photographic material comprises a support having provided thereon at least one silver halide emulsion layer which has a substantial influence upon image density and at least one light-insensitive hydrophilic colloid layer, wherein a hydrophilic colloid layer other than said silver halide emulsion layer contains a hydrazine derivative in a non-diffusing condition. With this photographic material, a super high contrast negative image can be obtained without decreasing sensitivity and gamma by the use of a developer containing not less than 0.15 mol/liter of sulfite ions and having a pH of from 10.5 to 12.3.

摘要： The present invention relates to a direct positive silver halide photosensitive material and a method for forming a direct positive image. By the use of a novel nucleating agent having a specific structural formula, the present invention provides a direct positive silver halide photosensitive material with an increased Dmax value and a decreased Dmin value, as compared with the use of the conventional nucleating agents, even if a small amount of the novel nucleating agent is used, and does not substantially reduce the Dmax value, even if the photosensitive material is kept in a high-humidity state for a long time before exposure.
