Definitions

  • this invention relates to rapid access photographic elements containing hydrazine compounds and to processing solutions related thereto.
  • Photographic silver halide elements have long been used to record images and are often preferred because they have excellent image reproduction characteristics and high speed.
  • lithography a host of
  • induction period during development, which means that there is an initial lag period during which processing is relatively slow prior to infectious development when the high contrast and density are achieved.
  • the developing solutions for elements containing hydrazine compounds typically contain conventional silver halide developing agents such as hydroquinone or derivatives of hydroquinone. It is sometimes necessary to add a super-additive developing agent such as phenidone or metol, for example. These developing solutions are necessarily kept at a fairly high pH which is deleterious to the life expectancy of the solution itself and to the processing equipment. Additionally, these prior art developing solutions tend to be environmentally hazardous and will produce sludge in the developing tanks.
  • Ruger, U.S. Patent 4,937,160 teaches a novel group of hydrazides which can be used in a manner similar to the prior art hydrazines but with the advantage of somewhat lower processing pH. Silver halide elements containing these novel hydrazides, however, also suffer from the other disadvantages noted above, such as the appearance of "pepper" and the relative toxicity of the developer solutions.
  • ascorbic acid or any of its derivatives as developing agents for silver halide elements
  • James, J. Amer. Che . Soc, Jan. 1944 (Communication No. 951 from the Kodak Research Laboratories) states that ascorbic and iso-ascorbic acid can be used as developing agents for silver halide elements.
  • James, U.S. Patent 2,688,549 teaches the use of a developer solution comprising 3-pyrazolidone and ascorbic acid or its sugar analogs.
  • these prior art developing solutions were very slow and found little or no commercial success.
  • It is an object of this invention to provide an improved system for rapid access processing of photographic silver halide elements comprising, in combination: a) a photographic silver halide element of the type containing a hydrazine compound; and b) a developer solution comprising at least one ascorbic acid developing agent selected from the group consisting of ascorbic acid, derivatives thereof, and salts of' either.
  • It is another object of the invention to provide an improved process of image formation comprising the step of developing an imagewise exposed photographic element of the type containing a hydrazine compound in a developer solution comprising at least one ascorbic acid developing agent selected from the group consisting of ascorbic acid, derivatives thereof, and salts of either.
  • a developer solution comprising at least one ascorbic acid developing agent selected from the group consisting of ascorbic acid, derivatives thereof, and salts of either.
  • an improved rapid access developer solution for hydrazine containing films comprising an ascorbate developing agent, at least one alkanol amine and having a pH in the . range 10.65 to about 12.0.
  • the developing agents that are useful within the metes.and bounds of this invention include ascorbic acid r its derivatives, such as L- or D-ascorbic acid as well as erythorbic acid (also known as iso-erythorbic acid) and the alkali salts of either, for example. These developing agents are effective when used alone or in combination with known hydroquinone developing agents.
  • a mixture of sodium L-ascorbate and L-ascorbic acid or sodium erythorbate is the developing agent and no hydroquinone is present in the developer solution.
  • the preferred embodiment also contains a small amount of a super- additive developer, such as l-phenyl-3-pyrazolidone or derivatives thereof, among others.
  • the developer solutions of the present invention contain at least one alkanol amine in amounts suitable to effect the desired development rates.
  • alkanol amines suitable for use in the present developer solutions include those commonly employed by the prior art in the so-called w lith processing field," such as 1- piperidinethanol; 3-piperidino-l,2-propanediol; 1- methyl-2-piperidenemethanol; 1-(2-hydroxyethyl)- piperazine; 1,4-bis-(2-hydroxyethyl)-piperazine; diethanolamino ethanol; 3-(diethylamino)-1,2- propanediol; and N-butyl diethanol amine, among others.
  • developer adjuvants preferred for the developing solutions according to this invention include antioxidants (e.g. alkali metal sulfites) , sequestering agents (e.g. ethylene diamine tetraacetic acid, sodium salt), development accelerators (e.g. polyalkylene oxides) and the like. Buffers and pH adjusting compounds may also be mentioned here. Antifoggants and restrainers (KBr, Benzotriaizole PMT, etc.) may also be employed as is well known in the art.
  • Silver halide emulsions useful within the ambit of this invention include any of the commonly available silver halides such as silver bromide, silver chloride, silver iodide or mixtures of two or more of these halide salts. These emulsions may be precipitated by any of the conventional and well-know techniques such as splash or balanced double jet, for example. After precipitation of the grains in a small amount of gelatin, the grains are conventionally dispersed in a bulking amount of gelatin and then brought to their optimum sensitivity with gold and sulfur salts, as is well-known to those of normal skill in the art. Sensitizing dyes, antifoggants, dispersing agents, coating aids and hardeners may also be added if desired.
  • these emulsions will contain one of the prior art and known hydrazine compounds such as those previously described, with one of the hydrazides of the aforementioned R ⁇ ger, U.S. Patent 4,937,160 preferably being used in accordance with the teachings of that patent.
  • a most preferred silver halide emulsion will contain 98% bromide and 2% iodide, and will contain 80 g of gelatin per mole of silver halide present.
  • This emulsion will be sensitized with sodium thiosulfate and green sensitizing dye and will contain 250 mg of 2-(4- Benzyloxy ⁇ henyl)-l-Pyridinium acetyl-Hydrazine Bromide (BOP-HMP) per 1.5 moles of silver halide present.
  • BOP-HMP 2-(4- Benzyloxy ⁇ henyl)-l-Pyridinium acetyl-Hydrazine Bromide
  • standard antifoggants, coating aids, etc. are added and the emulsion coated on a 4 mil dimensionally stable, polyethylene terephthalate film support to about 4.4 g/m 2 coating weight.
  • Other useful supports such as cellulosic supports (e.g. cellulose acetate, etc.) and other common supports for the coating of silver halide elements which are well-known in the prior art may be used.
  • a typical and preferred developer solution of this invention will contain the following ingredients in the
  • a standard control developer commonly used for the development of hydrazine containing films was prepared as follows: Amount (g/liter of
  • a film was prepared from an emulsion which comprised 98 mol % bromide and 2 mol % iodide dispersed in 80 gm of gelatin per mole of silver halide. This emulsion was brought to its optimum sensitivity by digestion with sodium thiosulfate (sulfur salt) and Green Sensitizing Dye for 40 minutes at a temperature of 130°F.
  • antifoggants, stabilizers, coating/wetting aids and hardeners were added as well- known to those of normal skill in the art along with 250 mg/1.5 mole of silver halide of a hydrazide such as that taught in the aforementioned R ⁇ ger patent (BOP-HMP) .
  • BOP-HMP R ⁇ ger patent
  • the emulsion was then coated to 4.4 g/m 2 on a 4 mil biaxially oriented and heat-set polyethylene terephthalate film support having well-known resin and gel sub layers applied thereto.
  • a thin layer of gelatin e.g., 10 mg/dm 2
  • N-butyl diethanol amine is the preferred alkanol amine, not because of any superior results as compared to the other alkanol amines of this invention, but because it is less toxic and has a less objectionable odor.
  • Example 4 To the standard control developer of Example 1, an addition of 5.0 gm/1 of sodium L-ascorbate was added and film prepared, exposed, developed for 60 seconds, fixed, washed and dried as in Example 1. A reading of the pepper- level on this film was made by examination with a 50X magnifier and compared to similarly treated film in the standard control developer. A very significant reduction in the size and frequency of the pepper spots was observed for the ascorbate-containing developer, without appreciable effect on sensitometry or deterioration in dot quality. Similar advantageous effects were observed when sodium D-isoascorbate, sodium erythorbate and dehydroascorbic acid were substituted for the sodium L-ascorbate. EXAMPLE 4
