Definitions

  • This invention relates to a method of processing a silver halide colour photographic light-sensitive material and, more particularly, to a method of processing a silver halide colour photographic light-sensitive material, in which a color developer can be excellent in the storage of long standing and a maximum colour density can satisfactorily be obtained and, further, a rapid development can be made.
  • silver halide colour photographic light-sensitive materials have been subjected to running treatments with an automatic processing apparatus installed at each photo-finishing laboratory.
  • an automatic processing apparatus installed at each photo-finishing laboratory.
  • it has been requested, as one of service improvements to users, to process users' photographic products and return the finished ones to them, within not only the same day when the photo-finishing orders were received and, but also several hours after receiving orders, recently, so that a rapid processing technolgy has been urgently demanded.
  • This invention relates to the above-mentioned technologies [1] and [3] out of those [1], [2] and [3].
  • the so-called light-sensitive materials for colour paper use generally contain silver chlorobromide as the silver halide composition thereof.
  • the silver bromide content mentioned in the above technology (1) of [1] is reduced, that is, the silver chloride content is increased, a development may be accelerated by themselves and the bromide ion concentration of a developer may also be reduced when a running treatment is kept on successively, so that the light-sensitive materials may have the characteristics that a development acceleration may readily be made and a low quantity replenishment of developer may also be possible.
  • DE-A-3412712 describes colour developers containing hydroxylamine or N-alkyl hydroxylamine as preservatives. These can be used with silver halide emulsions of various compositions.
  • the Examples of DE-A-3412712 describe the development of a material having silver chloro-bromide emulsion layers with silver bromide contents of, respectively, 80 mol % (blue-sensitive), 70 mol % (green-sensitive) and 50 mol % (red-sensitive).
  • the present inventors have studied on the methods of processing silver halide colour photographic light-sensitive materials having the above-mentioned silver halide content reduced suitably for paper use, and resultingly found that, while these light-sensitive materials may be processed more rapidly than the conventional type silver halide colour photographic light-sensitive materials using silver chlorobromide having a high silver bromide content (such as a 90 mol% silver bromide content), there is a problem that a maximum colour density, that is one of the most essential characteristics of light-sensitive materials, is lowered.
  • colour developers each contain an aromatic primary amine type colour developing agent such as paraphenylenediamine and so forth, hydroxylamine and sulfites used as a preservative for preventing the air-oxidation and so forth of the colour developing agent, benzyl alcohol for accelerating colour developments, other additives, and so forth.
  • aromatic primary amine type colour developing agent such as paraphenylenediamine and so forth
  • hydroxylamine and sulfites used as a preservative for preventing the air-oxidation and so forth of the colour developing agent
  • benzyl alcohol for accelerating colour developments, other additives, and so forth.
  • the inventors have also studied on the system using only a sulfite not any hydroxylamine as the preservative. Resultingly, the standing stability of the colour developer tested was maintained to some extent, however, an dye image was fogged seriously when processed with a long-stored colour developer.
  • a fog production may colosely relate to the deterioration of a colour developer used.
  • Fogs are particularly liable to be produced when raising a pH of a colour developer, a temperature for colour development process and a concentration of the colour developing agent contained in a colour developer. or when prolonging a storage of long standing of a colour developer. Therefore, the main cause of fog production is supposed to be the decomposed or oxidized products produced by partly decomposing or oxidizing the colour developing agent of the colour developer.
  • the above-mentioned decomposed or oxidized products of color developing agents include, for example, a semiquinone or quinoneimine that is an oxidized product of a colour developing agent, a paraaminophenol produced by receiving a deamination reaction or a quinonemonoimine that is the oxidized product thereof, the sulfurous acid addition products of quinonediimine or the quinonmonoimine or the oxidized products thereof, and so forth.
  • Some of these products make a coupling reaction with couplers upon oxidizing silver halide present in the unexposed areas of a light-sensitive material or make a coupling reaction directly with couplers so as to form a dye in the regions of the unexposed areas of a colour photographic light-sensitive material, where any dye ought not to be formed, and fogs are produced in white regions.
  • a light-sensitive material comprising three emulsion layers, i.e., blue-, green- and red-sensitive layers
  • the fog production on each unexposed layer will appear in a mixed colour, so that these fogs and the mixed colour will seriously deteriorate a photographic image quality.
  • the present inventors have studied on the methods of processing silver halide colour photographic light-sensitive materials capable of maintaining the preservability of a colour developer, inhibiting fogs and, particularly, preventing a maximum colour density from lowering and, further, suitable for a rapid processing. Resultingly, the inventors have found the fact that the above-mentioned problems can be solved by processing the silver halide colour photographic light-sensitive materials each having a specific silver halide composition, in the presence of a specific preservative, so that this invention has finally been achieved.
