Definitions

  • the present invention relates to a silver halide color photographic light-sensitive material to be used as a color photographic film of a format different from conventional formats, in which image qualities, particularly sharpness and color reproducibility are improved and the area of an imaging area and the number of perforations are specified.
  • a camera having a zoom lens or a bifocal lens is increased in size with the increase in focal length on the telephoto side, resulting in a poor portability.
  • miniaturization of the camera is given priority, on the other hand, no sufficient telephoto effect can be imparted to the camera.
  • U.S. Patents 3,490,844, 4,583,831, and 4,650,304 have proposed techniques of so-called pseudo zooming by focusing attention on the advance in performance of recent color negative films.
  • this pseudo zooming technique information about the focal length of a lens, which is input to a film during photographing by some means, is detected in the stage of printing to enlarge portions of an imaging area of a negative film, thereby obtaining the telephoto effect.
  • Miniaturization of a lens can be expected by the use of the pseudo zooming technique because the focal length of the lens can be shortened by this technique.
  • the technique requires a lens with an image circle corresponding to the 135 format and also makes it difficult to realize a camera much more compact than current 135-format cameras because of the use of a cartridge corresponding to the 135 format.
  • the pseudo zooming technique is also unpreferable in terms of resource saving because the ratio of an effective area of an imaging area used in formation of prints to an overall film area is reduced. Furthermore, a variation in image quality between prints obtained from the same film is one of complaints of users.

  • each of JP-A-2-273743 and JP-A-2-273744 discloses a color negative film set in a cartridge, which contains a compound represented by Formula (A) below and releasing a precursor of a development inhibitor, and in which the effective area and the aspect ratio (the ratio of the lateral length to the longitudinal length) of an imaging area of each frame to be exposed are defined:

  • TAC cellulose triacetate
  • This TAC base has no optical anisotropy and hence has a high transparency.
  • the TAC base also has an excellent property of eliminating curling once formed after development because it has a high water absorption.
  • This high water absorption leads to a high humidity dependency, with the result that the state of curling at photographing changes in accordance with the humidity at which the film is stored in the form of a roll. This gives rise to a serious problem of inability to obtain a constant image quality.
  • the TAC base also has a drawback of a low dynamic strength.
  • an object of the present invention to provide a silver halide color photographic light-sensitive material which is totally improved in image qualities, particularly sharpness and color reproducibility by taking into account not only light-sensitive layers but also a support constituting the light-sensitive material and the processed form of the material.

  • Formula (A) A-(Time) n -W wherein A represents a group capable of releasing (Time) n -W upon reacting with the oxidized form of a color developing agent, Time represents a timing group, W represents a group which exhibits a development inhibiting effect after released from (Time) n -W, and n represents 1, 2, or 3.
  • the image qualities, particularly the sharpness and the color reproducibility of the resultant color images are improved, and the support can be made thin. This makes it possible to reduce the area of an imaging area without impairing the image qualities and to decrease the size of a cartridge. Therefore, the silver halide color photographic light-sensitive material of the present invention is useful in miniaturizing cameras.

Note that the processing was performed by using the processing solutions obtained after continuous (running) processing was performed for a sample, which was separately imagewise-exposed, at a rate of 1 m2/day for 15 days.
  • the processing steps and the compositions of the processing solutions were as follows. Processing Steps Step Time Temperature Quantity of replenisher* Tank volume Color development 3 min. 05 sec. 38.0°C 23 ml 10 l Bleaching 50 sec. 38.0°C 5 ml 5 l Bleach-fixing 50 sec. 38.0°C - 5 l Fixing 50 sec. 38.0°C 16 ml 5 l Washing 30 sec. 38.0°C 34 ml 3.5 l Stabilization (1) 20 sec. 38.0°C - 3 l Stabilization (2) 20 sec. 38.0°C 20 ml 3 l Drying 1 min. 30 sec. 60°C * The quantity of replenisher was a quantity per 1.1 m of a 35-mm wide sample (corresponding to one 24-Ex. film)
  • the stabilizing solution was used by a counter flow system from (2) to (1), and the overflow solution of the washing solution was introduced entirely to the fixing bath.
  • the replenishment of the bleach-fixing solution was performed by forming notches in the upper portions of the bleaching tank and the fixing tank of the automatic developing machine so that the overflow solution produced when the replenishers were supplied to the bleaching and fixing tanks was flowed entirely to the bleach-fixing bath.
  • the quantities of the developing solution, the bleaching solution, the bleach-fixing solution, and the fixing solution carried over to the bleaching step, the bleach-fixing step, the fixing step, and the washing step were 2.5 ml, 2.0 ml, 2.0 ml, and 2.0 ml, respectively, per 1.1 m of the 35-mm wide light-sensitive material.
  • the crossover time of each step was six seconds, and this time was included in the processing time of each previous step.
  • compositions of the processing solutions are presented below.
  • Tank solution (g) Replenisher (g) Ammonium 1,3-diaminopropane tetraacetato-ferrate(III) monohydrate 130 195 Ammonium bromide 70 105 Ammonium nitrate 14 21 Hydroxyacetic acid 50 75 Acetic acid 40 60 Water to make 1.0 l 1.0 l pH (controlled by ammonia water) 4.4 4.4
  • Tap water was supplied to a mixed-bed column filled with an H type strongly acidic cation exchange resin (Amberlite IR-120B: available from Rohm & Haas Co.) and an OH type strongly basic anion exchange resin (Amberlite IR-400) to set the concentrations of calcium and magnesium to be 3 mg/l or less. Subsequently, 20 mg/l of sodium dichloroisocyanurate and 150 mg/l of sodium sulfate were added. The pH of the solution ranged from 6.5 to 7.5.
  • the resultant prints were so cut as to leave only image portions behind, and the sharpness of each print was evaluated on a gray plate (reflection density 0.18) under a fluorescent lamp for color evaluation by ten male monitors and ten female monitors.
  • the evaluation was performed by using the print obtained from the film made from the multilayered color light-sensitive material C-1 of Group I as a reference and sequentially comparing this reference with other prints one at a time. A print found to be better than the reference was given +1, a print found to be equivalent to the reference or difficult to determine was given 0, and a print found to be worse than the reference was given -1. After the determination, an arithmetic means of these values was calculated for each print.
  • the color reproducibility was evaluated by measuring the cyan density of a magenta dye image of the color checker chart photographed in a color negative film and checking the degree of color turbidity by obtaining the difference with respect to the value of the multilayered color light-sensitive material C-1 as a reference.
  • Table 4 reveals that the films of Group II each having the polyester support were found to be better in sharpness than those of Group I which were current 135-format films. The reason for this is considered that the flatness of an imaging area to be exposed could not be maintained during photographing because the number of perforations per frame was large in the films of Group I. In fact, some monitors backed up this by pointing out that blurs were found in peripheral portions or central portions of these prints. On the other hand, the films of Group III each having an imaging area of 3 cm2 or less was found to be obviously poor in sharpness, demonstrating that it is difficult to reduce the size of an imaging area to 3 cm2 or less while maintaining the image quality.
  • the multilayered color light-sensitive materials A-1 of the present invention and comparative light-sensitive material C-1 using a compound represented by Formula (A) obviously caused less color turbidity than and were therefore superior in color reproducibility to A-3 and C-2 having the comparative compound (1) in place of the compound represented by Formula (A).
  • the films of Groups II and III having reduced imaging areas were improved in color reproducibility compared to the films of Group I having large imaging areas although the differences were small. The reason for this is unknown, but it is estimated that this was caused by some dynamic factor applied on a hydrophilic colloid layer when a film was wound around a spool.
  • PBC-2, PBC-3, PBC-6, PBC-9, PBC-10, and PBB-3 exemplified as polyester compounds were used to perform melting, biaxial orientation, and thermal fixing in accordance with the method described in Example 1, forming supports 80 ⁇ m thick. A subbing layer and a back layer were coated on each support, and a heat treatment was performed for each resultant support at a temperature lower by 10°C than the glass transition point (Tg) of each polyester compound. Layers with the compositions shown in Example 1 were multi-coated on each of these supports to manufacture multilayered color light-sensitive materials.
  • the multilayered color light-sensitive materials A-1, D-1, and D-3 manufactured in Example 1 were processed to have a width of 24 mm, and perforations were formed in the both side edges in the longitudinal direction of each resultant film such that one perforation was formed per frame in each side edge.
  • Each resultant film was put into the film cartridge described in JP-A-2-273740.
  • a camera was also remodeled so as to be able to load this cartridge.
  • An object to be photographed was photographed following the same procedures as in Example 1 such that the size of an imaging area was 30.0 mm ⁇ 12.0 mm (area of imaging area to be exposed 3.60 cm2, aspect ratio 2.5).
  • each resultant film was put into the cartridge described in JP-A-2-273740. Photographing was similarly performed such that the imaging area size was 30.0 mm ⁇ 21.4 mm (area of imaging area to be exposed 6.42 cm2, aspect ratio 1.4) and was 30.0 mm ⁇ 16.7 mm (area of imaging area to be exposed 5.01 cm2, aspect ratio 1.80). In this photographing, a feed length of one frame of the film was set to 31.7 mm in correspondence with the imaging area size described above.
  • the distance was determined such that an object to be photographed (the upper half of a mannequin with a resolving power chart and a color checker chart) was just fitted in a longitudinal position of an image portion.
