Light-sensitive silver halide material for making direct-positive images.

摘要

Photographic light-sensitive silver halide material for forming direct-positive images comprising a support, a light-sensitive emulsion layer comprising unfogged internal latent image-type silver halide grains dispersed in a hydrophilic colloid binder and comprising a development nucleator, and at least one protective hydrophilic colloid layer, wherein said light-sensitive emulsion comprises at least one compound that during the development of said material in a surface developer provides iodide ions, the weight ratio of the hydrophilic colloid binder of said emulsion layer to silver halide expressed as silver nitrate ranging from 0.4 : 1 to 3 : 1, and said protective hydrophilic colloid layer having a thickness in dry state of 1 to 3 mu m. The present invention also relates to a method for making direct-positive images with such a photographic light-sensitive silver halide material.
