IPC: G03C7/30
Filed: 1980-01-16
Abstract: PURPOSE: To improve the graininess, sharpness and reproducibility of the titled material by forming a photosensitive silver halide emulsion layer contg. specified two kinds of development inhibitor releasing type compounds and a hydrophilic colloid layer on a support.  
     CONSTITUTION: On a support at least one photosensitive silver halide emulsion layer is formed contg. a diffusible substance consisting of the development inhibitor releasing type compound of formula I or the like having an amino group and the development inhibitor releasing type compound of formula II or the like having no amino group and inhibiting the development of silver halide by coupling with the oxidation product of an aromatic primary amine developing agent. A hydrophilic colloid layer contg. the diffusible substance may be formed adjacently to the emulsion layer.
