Definitions

  • the present invention relates to a method for processing a silver halide color photographic light-sensitive material (hereinafter referred to "a light-sensitive material" according to the occasion).
  • a processing method having improved adhesion of the processed light-sensitive material, improved wet-heat fading of a yellow dye, and improved magnetic output capacity of a light-sensitive material having a magnetic recording layer, even when a processing is conducted over a long period of time using a bleaching agent that is excellent in biodegradability (spontaneous decomposability).
  • fundamentals for the photographic process of a silver halide color photographic light-sensitive material consist of a color development step and a desilvering step, and the light-sensitive material is processed by these fundamental steps and other auxiliary steps using a processing apparatus, which is called an autoprocessor.
  • the desilvering step the developed silver produced in the color development step is oxidized, to become a silver salt, by an action of an oxidant (a bleaching agent) contained in a processing solution having a bleaching capacity, and further, the silver salt is removed from the light-sensitive material, by an agent capable of dissolving a silver ion (a fixing agent), which is contained in a processing solution having a fixing capacity.
  • materials having good biodegradability have lately been called for, from a global environmental protection point of view, in a movement against materials that are hardly biodegraded in the natural world, such as ethylenediamine-N,N,N',N'-tetraacetic acid and 1,3-propanediamine-N,N,N',N'-tetraacetic acid, which have been generally used as bleaching agents up to the present time.
  • materials having good biodegradability include diamine-type compounds, as disclosed in JP-A-("JP-A" means an unexamined published Japanese patent application) No. 313752/1992, and monoamine-type compounds, as disclosed in JP-A-Nos. 265159/1993 and 161065/1994.
  • the monoamine-type compounds which contain less of a nitrogen ingredient, are preferred of these materials having good biodegradability, from the environmental protection point of view.
  • the following facts have been confirmed: when a light-sensitive material is processed for a long period of time using a monoamine-type compound having good biodegradability, sometimes the processed light-sensitive material takes on adhesiveness, and consequently such problems arise that a color negative film is difficult to remove from an envelope, which is called a nega sheet; and further, such monoamine-type compounds tend to deteriorate wet-heat fading of a yellow dye, among image-forming dyes.
  • JP-A-95318/1994 describes processing the light-sensitive material having a magnetic recording layer with a bleaching solution containing a ferric complex salt of aminopolycarboxylic acid.
  • the said publication describes effects of a change in density of the processed light-sensitive material with a lapse of time under wet heat, and a solution's storage stability, it is silent on an influence on the reading capacity of the magnetic record.
  • An object of the present invention is to provide a method for processing a silver halide color photographic light-sensitive material, whereby adhesion of the processed light-sensitive material and wet-heat fading of a yellow dye are not deteriorated, even though a processing is conducted over a long time using a material having excellent biodegradability.
  • Another object of the present invention is to provide a processing method that does not lower the reading capacity of the magnetic record, even when a light-sensitive material having a magnetic recording layer is processed thereby.
  • a method for processing a silver halide color photographic light-sensitive material which method comprises steps of color developing a silver halide color photographic light-sensitive material, and then desilvering, and further washing and/or stabilizing it, wherein a processing solution having a bleaching capacity in the desilvering step contains a ferric complex salt of at least one compound represented by general formula(X) as set forth below, and further, a processing solution used in the desilvering step or subsequent steps therefrom contains at least one compound represented by general formulae (A) to (I), or at least one aminoglycoside selected from the group consisting of gentamicins, amikacin, tobramicin, dibekacin, albekacin, micronomicin, isepamicin, sisomicin, netilmicin, and astromicin: wherein R represents a hydrogen atom, an aliphatic hydrocarbon group, an aryl group, or a heterocyclic group; L 1 and L 2 each represent an alkylene group; and
