Definitions
- This invention relates to a development process and to combinations of substances influencing the development, used in this development process.
- wnereinz V C- represents an anion e.'g. a halogen anion, a nitrate anion, a bisulphate anion, or a bendotriazolium anion,
- aromatic nuclei of said compounds may be substituted e.g. with an alkyl radical, a halogen atom, an alkoxy radical, a cyano radical, an acyl radical, or an acylamino radical,
- These compounds influencing the development are preferably added to the composition of the light-sensitive silver halide emulsions in dissolved form in water or a mixture of water and water-miscible organic solvents, which do not impair the photographic characteristics of the emulsion.
- these compounds can. also be incorporated into the emulsion by imbibition by treating it with a solution containing these products or by diifusion from an adjacent water-permeable layer comprising these compounds.
- the compounds infiuencing the development according to the present invention can be added to the light-sensitive silver halide emulsion during different preparation steps of the light-sensitive material.
- they can be incorporated therein by a separate addition or they can be added as a mixture with one or more ingredients used in the formation of the silver halide grains, during the physical or chemical ripening or during another step preceding the coating of the emulsion.
- the compounds according to the above general formulae are preferably used in combination with watersoluble polyoxyalkylene compounds i.e. alkylene oxide condensation products as described e.g. in the US. Patent Specifications 1,970,578 by Conrad Schoeller and Max WittWer, issued Aug. 21, 1934, 2,240,472 by Donald R. Swan, issued Apr. 29, 1941, 2,423,549 by Ralph K. Blake, William A. Stanton, Titan Schulze, issued July 8, 1947, 2,441,389 by Ralph K. Blake, issued May 11, 1948, 2,531,832 by William A. Stanton, issued Nov. 28, 1950, 2,533,990 by Ralph K. Blake, issued Dec. 12, 1950, and the British Patent Specifications 920,637, filed May 7, 1959, 940,051, filed Nov.
- alkylene oxide condensation products together with the compounds influencing the development as described above can be added to the composition of the silver halide emulsion or to a Water-permeable layer, which together with the emulsion layer forms part of'a waterpermeable element.
- the alkylene oxide condensationproduetsand/or the compounds according to theabovengeneralformulae can also be added to the developing bath.
- alkylene oxide condensation product and iodonium compoundaccording'J-to the. above formulae depends on the very compound, on the nature of the colloid binder of the silver halide grains and on the kind of silver halide in the emulsion. In general, however, the above alkylene oxide condensation prod nets are added to the light-sensitive material in an amount of mg. to 10 g. per mole of silver halide. When incorporated into the developer they are used in amounts ranging from 0.1 g. to 10 g. per litre of developer.
- the amount of iodonium derivative incorporated into the light-sensitive material preferably ranges between mg. and g. per mole of silver halide.
- the derivative is used preferably in an amount varying between 0.1 g. to 20 g. per litre.
- the development acceleration and the increase of dot definition and of the development latitude obtained with the products according to the present invention can be combined with a chemical sensitisation by using in com bination with the above-mentioned condensation products chemical sensitising agents such as sulphur-containing compounds, e.g. allyl isothiocyanate, allyl thiourea or sodium thiosulphate, reducing agents such as the tin compounds described in the Belgian Patent Specifications 4'93,- 464, filed Jan. 24, 1950 and 568,687, filed June 18, 1958, by Gevaert Photo-Producten N.V., the imino-amino methane sulphinic acid compounds described in the British Patent Specification 789,823, filed Apr.
- chemical sensitising agents such as sulphur-containing compounds, e.g. allyl isothiocyanate, allyl thiourea or sodium thiosulphate
- reducing agents such as the tin compounds described in the Belgia
