摘要：
According to the present invention a method for producing a negative image is provided, comprising the following steps:
- image-wise exposing an imaging element comprising on a support, a light-sensitive silver halide emulsion layer comprising silver halide grains having an average volume of not more than 0.02µm3 and a layer containing non-light-sensitive water insoluble silver salt, to produce a latent image in said layer of light-sensitive silver halide
- developing said latent image to produce physical development nuclei of silver
- dissolving the non-light-sensitive silver salts using a silver salt complexing agent and
- allowing the thus formed silver salt complexes to diffuse to the layer containing said image-wise formed physical development nuclei of silver to image-wise deposit and develop said silver salt complexes on said image-wise formed physical development nuclei of silver in the presence of (a) developing agent(s).
