Definitions

  • the invention relates to a highly sensitive color photographic recording material with several silver halide emulsion layers of improved sharpness.
  • three silver halide emulsion partial layers of the same spectral sensitivity but different general sensitivity are to be used to improve the granularity of a partial color image, with each more sensitive partial layer being arranged further away from the substrate than each less sensitive sub-layer.
  • a maximum color density of at most 0.6 and altogether at most 1.0 is achieved in the middle and in the upper sub-layer, which can be achieved by reducing the coupler content, i.e. can be achieved by increasing the ratio of silver halide to coupler.
  • color photographic materials in particular color negative materials, have a structure in which at least one red-sensitive layer, one green-sensitive layer, one yellow filter layer and one blue-sensitive layer are applied to a support in the order given. Since the human eye has the greatest sensitivity in the green spectral range, the image generated in the green-sensitive layer has the greatest influence with regard to the subjectively perceived Sharpness. The sharpness of the image produced in the green-sensitive layer, however, suffers from the light scattering within the blue-sensitive layers located above the green-sensitive layer in the conventional structure specified above. In order to improve the sharpness, it has therefore already been proposed to arrange the green-sensitive layer above the blue-sensitive layers. Such structures are described for example in DE-OS 2 427 491, DE-AS 1 128 291 and US Pat.
  • DE-AS 1 128 291 there is a blue-sensitive layer (B) on a support (T), a red-sensitive layer (R), a green-sensitive layer (G) and a yellow filter layer (F) as the top layer.

  • R red-sensitive layer
  • G green-sensitive layer
  • F yellow filter layer
