Definitions

  • the present invention relates to a silver halide photographic light-sensitive material and a processing method therefor.
  • the invention is applicable both to a light-sensitive material suitable for rapid processing, and to a processing method for the similar material, and is adaptable to a technical field such as photomechanical light-sensitive material technology.
  • Reducing time for developing process (usually comprising developing, fixing, washing, and drying steps) entails, as one possible way, increase in a travelling speed of a light-sensitive material.
  • reducing time for developing process by increasing a roller-transporting speed causes problems such as (a) insufficient optical density (decrease of sensitivity, contrast and maximum density); (b) insufficient fixing; (c) insufficiently washed film; and (d) insufficiently dried film.
  • Insufficient fixing as well as insufficient washing result in discoloration and thus deterioration in image quality in preservation of a developed film.
  • One technique to solve these problems is to decrease an amount of gelatin used in a photographic film.
  • a photographic film incorporating a smaller amount of gelatin readily results in a photographic image of poor graininess.
  • a so-called "scratch-induced" image deterioration tends to occur after a developing process where the density of a rubbed area is higher than that of the remaining area.
  • a ultra-rapid processing is strongly needed because of the above-mentioned reasons.
  • the term "ultra-rapid processing" is defined as follows: a process wherein the leading edge of a film is inserted into an automatic developing equipment, and guided through a developing bath, travelling path, fixing bath, travelling path, washing bath, travelling path, drying unit, and then, the leading edge of the film comes out of a drying unit, and a total duration of this process [in other words, a quotient (sec.) obtained by dividing a total length (m) of a processing line by a travelling speed (m/sec.)] ranges from 20 to 60 seconds.
  • the reason why time for the travelling path is included in the calculation above is, as well known in the art, that photographic processing continues even in a travelling path because a processing solution of a preceding process remains in a swollen gelatin layer.
  • the object of the invention is to provide a silver halide photographic light-sensitive material and an appropriate processing method therefor, wherein the light-sensitive material is free from the preceding problems of a prior art even when subjected to such a rapid processing as a ultra-rapid processing of which total processing time is 20 to 60 seconds, and the light-sensitive material excels in sensitivity, fogging, and graininess, and is less prone to a "scratch-induced" image quality deterioration and pressure desensitization even with a smaller amount of gelatin incorporated.
  • a silver halide photographic light-sensitive material comprising a support having thereon at least one hydrophilic colloid layer, wherein the photographic material contains, as silver halide, silver chloride or silver bromochloride or silver bromochloroiodide each comprising not less than 60 mol% of silver chloride, and wherein the photographic material contains water of 5 to 16 g/m2 just coming from a washing step in a roller-transporting type automatic developing equipment.
  • FIG. 1 illustrates an automatic developing equipment used in Examples of the invention, and the equipment has a variable travelling speed.
  • a preferred amount of gelatin in the hydrophilic colloid layers including a light-sensitive silver halide emulsion layer is at a range of 2.00 to 3.20 g/m2.
  • an allowable water content is at a range of 5 to 16 g/m2 as mentioned above.
  • the preferred content is at a range of 8 to 13 g/m2.
  • the processing line speed is preferably faster than 1500 mm/minute, more preferably faster than 1900 mm/minute.
  • This antinomic problem can be solved by raising a processing line speed, which increases a relative efficiency of stirring a developing solution without causing any bubbling resulting in an irregularly developed image.
  • the problems which are possibly caused by a faster processing line speed, i.e. lowering of an optical density, lack of fixing, can be prevented by raising a travelling path ratio to a higher ratio than 0.75.
  • a travelling path of a photographic material in a processing solution is preferably more than 250 mm, more preferably more than 330 mm.
  • the silver halide photographic light-sensitive material of the invention contains, as silver halide, silver chloride, silver bromochloride, or silver bromochloroiodide.
  • Such silver bromochloride or silver bromochloroiodide contains not less than 60 mol%, preferably not less than 70 mol% of silver chloride.
  • the preferred average grain size of silver halide grains is at a range of 0.05 to 0.3 ⁇ m; and the silver halide grains are preferably in narrower size distribution not more than 15% in terms of a fluctuation coefficient defined as (standard deviation of grain size)/(average grain size)x 100.

  • sensitizers include active gelatin, sulfur sensitizers (such as sodium thiosulfate, arylthiocarbamide, thiourea, and arylisothiacyanate), selenium sensitizers (such as N,N-dimethylselenourea, and selenourea), reducing sensitizers (such as triethylenetetramine, and stannous chloride), and various noble metal sensitizers such as potassium chloroaurate potassium aurothiocyanate, potassium chloroaurate, 2-aurosulfobenzothiazole methylchloride, ammonium chloropalladate, potassium chloroplatinate, and sodium chloropalladate.

  • selenium sensitizers such as N,N-dimethylselenourea,
