Definitions

  • the present invention relates to a silver halide light-sensitive photographic material, more specifically to a silver halide light-sensitive photographic material for photodisplay application which suits rapid processing and has good sharpness.
  • a typical display method with a color photograph in such locations as department stores, restaurants, hotel lobbies and subway platforms is a "transmittance system (back-light system) where an image formed on a support is displayed by light illuminated from the back of the image; this system is known to provide vivid image in a specific environment such as dark room or the outdoors at night.
  • back-light system back-light system
  • the photographic material employed requires higher image density than that of ordinary color paper.
  • such a material inevitably requires much increased coating amounts of silver halide and coupler than ordinary color paper, which results in requiring as double processing time as ordinary color paper and therefore, makes it necessary to process the photographic material more rapidly.
  • Configuration, size and composition of silver halide grains in a silver halide emulsion for a photographic material greatly affect a developing speed, and especially the composition of halide most significantly affects it; it is well known that silver halide of high chloride content can notably accelerate developing.
  • a dye is added to a hydrophilic colloid layer in order to absorb light of a specific wavelength for controlling a sensitivity of a photographic emulsion. Also, a dye is added to inhibit halation or irradiation for improving sharpness of a photographic material.
  • the dyes used for these applications are requested to have prescribed spectral absorption characteristics for the respective applications; to be thoroughly decolored, readily eluted from a photographic material and thereby prevent stain on the material after processing; to exert no adverse effects to a photographic emulsion such as sensitization, desensitization and fogging; and to have good stability in a coating solution and a photographic material.
  • the photographic material for display is requested to more strictly satisfy the above requirements since it contains a larger amount of dye in order to attain higher sharpness.
  • oxonol dyes having two pyrazolone skeletons have been used as a useful dye that least adversely affect a photographic emulsion since they are decolored in a processing solution and readily eluted from a photographic material.
  • the sensitization to an undesirable spectral range is liable to result in worse image quality because of color imbalance in a printing process. Fog is caused most likely by an eluted or decolored dye or its decomposed product activated in a processing solution.
  • the larger sensitivity fluctuation by temperature or humidity variation results in lack of stable image quality depending on storage conditions such as temperature/humidity at a laboratory.
  • EP-A-0362734 which is an earlier document according to Article 54(3) EPC, describes photographic materials having an opaque polyethylene-laminated paper support, at least one emulsion layer containing grains having a silver chloride content of not less than 90 mole % and at least one layer containing an oxonol dye.
  • the background art discussed therein describes different types of dyes for light sensitive materials.
  • the object of the present invention is to provide a rapidly processable silver halide light-sensitive photographic material containing a dye that is inert in an emulsion and capable of providing an image of high sharpness.

  • the silver halide grains may be mixed with silver halide grains of different compositions.
  • the silver halide grains of the high chloride content share not less than 80 mole%, preferably not less than 90 mole% in the total silver halide grains contained in the same layer.
  • the size of the silver halide grains used for the invention is preferably 0.1 to 1.5 ⁇ m, more preferably 0.3 to 1.0 ⁇ m.
