Definitions

  • the present invention relates to a silver halide photographic material having a dyed hydrophilic colloid layer, and more particularly to a silver halide photographic material having a hydrophilic colloid layer containing a dye which is photochemically inactive and is easily decolored and/or dissolved out in a photographic processing step.
  • a colored layer is usually formed at the side farther from the support than the photographic emulsion layer.
  • a colored layer is known as a filter layer.
  • a filter layer may be added between the photographic emulsion layers.
  • a colored layer known as an antihalation layer is provided to prevent dimming of images (halation) caused by light that is scattered during or after passing through photographic emulsion layers, which scattered light is reflected at the interface between the emulsion layer and the support and/or at the surface of the support opposite to the emulsion layer side, and then reenters the photographic emulsion layer.
  • the antihalation layer is sometimes interposed between these photographic emulsion layers.
  • the photographic emulsion layer(s) can be colored to prevent a reduction in image sharpness caused by light scattering at photographic emulsion layer(s) (this phenomenon is generally known as "irradiation").
  • colored layers are formed of hydrophilic colloids.
  • a dye is usually incorporated in the hydrophilic colloid layers.
  • the dye being used for the purpose must satisfy the following requirements.
  • the colored layer is a filter layer or an antihalation layer provided at the same side as the photographic emulsion layer side of the support, it is frequently required that the layer only is selectively colored and the coloring does not substantially affect other layers. The reason is that if the coloring affects other layers, it not only provides a harmful spectral effect to other layers, but also the efficacy of the filter layer or the antihalation layer is reduced.
