| titleOfInvention | Method for making direct-positive photographic images |
| abstract | The present invention provides a method for making direct-positive photographic images comprising the steps of image-wise exposing a photographic light-sensitive silver halide material comprising a support and a layer of an internal latent image-type silver halide emulsion the pAg of which has been adjusted to a value of at least 8.5 before coating, and developing said exposed photographic silver halide material in a surface developer in the presence of at least one development nucleator which is not able to react with but which is able to adsorb weakly on the surface of the silver halide emulsion crystals prior to development, but which contains a group protected against reaction with silver halide and which is transformed during development in a nucleating derivative with an enhanced reactivity for the silver halide crystals. Photographic materials comprising these novel development nucleators are also described. |
