Definitions

  • the invention is related to a processing method of a light-sensitive silver halide photographic material having satisfactory surface characteristics after rapid processing in hardener free processing solutions.
  • a solution for this may be offered by coating a thicker antistress layer with an increased amount of binder e.g. gelatin.
  • binder e.g. gelatin.
  • these increased amounts have the advantage of giving rise to more surface glare after processing, an inadmissable contamination or sludge formation may occur in the processing solutions.
  • a thicker antistress layer may retard the processing and drying velocity. This is obviously contradictory to the trend to develop rapid processing systems with films having thin coating layers.
  • fixing solutions free from aluminum ions as a source of hardening agent provide the possibility to enhance the pH value and to reduce the unagreable odour thereof.
  • the objects of the present invention can be attained by a method of processing an image-wise exposed light-sensitive silver halide material by the steps of developing, fixing in a fixer solution containing less than 4 g per litre of aluminum ions expressed as an equivalent amount of aluminum sulphate, rinsing and drying; characterised in that said material comprises a support and on one or both sides thereof at least one light-sensitive silver halide emulsion layer and a gelatinous protective antistress layer, wherein said antistress layer comprises at least one polymer latex in such an amount that there is a ratio by weight of latex to gelatin from 0.5 to 1.5 (more preferably from 0.9 to 1.5) and wherein said material is hardened to such an extent that its swelling degree after immersing said material for 3 minutes in demineralised water of 25 °C is not more than 300 % (and more preferably not more than 200 %).
  • Preferred polymer latices used in the protective antistress layer of the light-sensitive silver halide material used in the processing method according to the present invention are cross-linked polymers and are prepared as described e.g. in US-A 4,301,240 by emulsion polymerisation of aliphatic esters of acrylic and/or methacrylic acid in water in the presence of polyfunctional cross-linking monomers and an emulsifier, followed by saponification of the obtained copolymer.
  • emulsion polymerisation copolymers with a molecular weight well above 500,000 are obtained and the average particle size of the latex is smaller than 150 nm.
  • Another example of the synthesis of ionic cross-linked copolymers can further be found e.g. in EP-A 0 452 568 and the corresponding US-A 5,472,832.
  • a preferred latex of an ionic copolymer for use in the gelatinous protective antistress layer of a light-sensitive silver halide material is a copolymer of butylmethacrylate and acrylamide-N-isobutylsulphonic acid sodium salt as represented in the formula (I).
  • a particularly preferred latex is a polyurethane latex, which is preferably in the form of a dispersion of an aliphatic anionic polyurethane.
  • IMPRANIL 43056 trademarked product from BAYER AG, Leverkusen, Federal Republic of Germany
  • This IMPRANIL-latex is a 40 % aqueous dispersion of polyurethane prepared from DESMODUR W (trademarked product from BAYER AG), which is a dicyclohexylmethane diisocyanate, and a polyester having a low molecular weight of about 800.
  • the average particle size of the latex may vary between 0.02 and 0.2 ⁇ m.
  • the polyurethane is added to the coating solution as an aqueous latex dispersion.
  • An especially useful polyurethane is the one having a highqual amount of urethane groups, in order to get a high degree of cross-linking and as a consequence low tendency to sticking. Moreover the presence of a lubricant in an outermost afterlayer on top of the protective antistress layer comprising said polyurethane dispersion may be favorable.
  • Said polyurethane latex can moreover be loaded with e.g. a developing agent by addition of the aqueous loadable polyurethane latex to a solution of useful agent(s) as e.g. a developing agent in a water-miscible organic solvent as e.g. acetone, or by simultaneous addition of said latex and said solution to an aqueous gelatinous solution as gelatin is a preferred binder for this loaded latex.
  • a mixture of developing agents including a dihydroxybenzene like hydroquinone and a 3-pyrazolidine-1-one developing agent as e.g.
  • 1-phenyl-3-pyrazolidine-1-one also known as "phenidone", being an electron transfer agent or super additive developer, can be used in combination, in that case preferably in a respective molar ratio of from 2/1 to 10/1.
  • dihydroxybenzene or dihydroxybenzenes is (are) preferably present in an amount of from 0.05 to 0.5 g for a coverage of silver halide equivalent with 1 g of silver nitrate.
  • Ascorbic acid, iso-ascorbic acid whether or not in combination with the preferred developing agent(s) can also be used. In this way a so-called "activation material" can be obtained which can be developed by means of an alkaline solution.
  • the latex should be present in the gelatinous protective layer(s) of the material to be processed in an amount in order to reduce the relative deviation of glare measured by reflection measurements as described in ASTME-D523 at a reflection angle of 60° to a value of not more than 2 %. Therefore measurements of glare are performed by means of a reflectometer under an angle of 60° at 10 different sites at the processed film surface in two different developing conditions: one in the presence in the fixer solution of at least 4 g of aluminum expressed as an equivalent amount of aluminum sulphate in the processing solutions and one in the absence thereof as will become clear from the Examples.
  • the commercially available G334 fixer trademarked product from Agfa-Gevaert NV, used in the tests, contains 5.44 g of aluminum sulphate in a fixer solution ready-for-use.
  • developer solutions may contain a hardening agent, but in a preferred embodiment said solutions are also free from hardening agents.
  • said latex polymer(s) coated in the gelatinous protective antistress layer is (are) present in an amount of at least 50 % by weight versus the total amount of gelatin present therein as a binder, and even more preferably in an amount of at least 90%.
  • the maximum ratio by weight of latex polymer(s) to gelatin binder is preferably 1.5.
  • said latex-type (co)polymers may optionally be present in a gelatin free afterlayer (if present) applied over the protective antistress layer and even in one or more emulsion layer(s) coated between said protective antistress layer and a subbed support, the subbing layer of which may be overcoated with at least one gelatinous intermediate layer.
  • the swelling degree of said photographic material to be processed according to the method of this invention after immersing said material for 3 minutes in demineralised water of 25 °C shouldn't exceed 300 % and even more preferred shouldn't exceed 200 %.
  • Said swelling degree expresses the requirement to sufficiently harden the binder in the light-sensitive silver halide photographic material used in processing method of this invention.
  • the following method is applied. After incubating a sample of a light-sensitive silver halide photographic material at 57 °C and 34 % RH for 3 days the thickness (a) of the layer assemblage is measured. Thereafter the sample is immersed in distilled water at 21°C for 3 minutes and the thickness (b) of the swollen layer is measured by means of the technique described in US-A 4,414,304.
  • the swelling ratio is then calculated as: (b-a) /a x 100 (%).
  • Layers and layer arrangements which can be applied to the film material in the processing method according to the present invention are those described in EP-A 0 752 617, in EP-A's 0 712 036 and 0 712 034, in EP-A's 0 677 773 and 0 678 772, in EP-A's 0 610 608; 0 610 609 and in EP-A 0 569 075, in US-A's 4,092,168 and 4,311,787; in DE 2,453,217 and in GB Patent 7,907,440.

  • the gelatin can also be an enzyme-treated gelatin as described in Bull. Soc. Sci. Phot. Japan, N° 16, page 30 (1966).
  • said gelatin can be replaced in part or integrally by synthetic polymers as cited hereinbefore or by natural or semi-synthetic polymers. Natural substitutes for gelatin are e.g.
