titleOfInvention | Direct positive silver halide emulsion and color diffusion transfer light-sensitive material using the same |
abstract | (57) [Summary] (Modified) [Purpose] To provide an internal latent image type direct positive silver halide emulsion having a high S / N and improved low light intensity reciprocity characteristics, and a color diffusion transfer photosensitive material using the same. provide. [Structure] A tabular silver halide grain having an average grain diameter of 0.3 μm or more and an aspect ratio (equivalent circle diameter of silver halide grain / grain thickness) of 2 or more and 100 or less is used as a projection area of all silver halide grains. In an internal latent image type direct positive silver halide emulsion characterized by containing 50% or more, P Particles are formed in the presence of b ions, and chemical sensitization of core particles is performed in the presence of at least one compound selected from compounds represented by the general formulas [A], [B] and [C]. Internal latent image type direct positive silver halide emulsion. And a color diffusion transfer photosensitive material using the same. Example of [A] CH 3 SO 2 SNa Example of [B] C 8 H 17 SO 2 SCH 2 CH 3 Example of [C] C 2 H 5 SO 2 SCH 2 CH 2 SO 2 CH 2 CH 2 SSO 2 C 2 H 5 |
