Definitions

the invention relates to a method for stabilizing photographic silver images by treatment with an aqueous aftertreatment bath.
the image tone may shift over time or in whole from black to brown or yellow.
This change in the image tone can be based on a conversion of the silver image into silver sulfide, which can occur, for example, if the washout is insufficient after fixation with sodium thiosulfate.
a similar disturbing image tone shift occurs when oxidizing gases are exposed to silver photographic images.
the oxidation of the image silver creates water-soluble silver salts that can diffuse in the material.
This soluble silver salts finely divided yellow to red-brown colored colloidal silver is formed, or brown colored silver compounds are formed.
such disturbing changes occur in the finished photographic silver image in the form of so-called microspot defects.
the invention thus relates to a process for stabilizing a photographically produced silver image by treating the finished silver image with an aftertreatment bath, which is characterized in that the aftertreatment bath contains aminotetrazole of the formula I. or a mercaptotetrahydrotriazine of the formula II wherein R1, R3 and R4 independently of one another are hydrogen, saturated or unsaturated, optionally substituted, for example by phenyl, with aliphatic groups having up to 6 carbon atoms, such as methyl, ethyl, propyl, butyl, allyl, benzyl or phenylethyl, or aryl groups, in particular phenyl; and R2 is hydrogen, saturated or unsaturated aliphatic groups with up to 6 carbon atoms, such as methyl, ethyl, butyl or allyl, it being possible for the aliphatic groups to be substituted by hydroxy, alkoxy, amino, halogen or phenyl, such as hydroxymethyl
aminotetrazole used in the invention is known.
the preparation of the mercaptotetrahydrotriazines is described in US-A-3,712,818.
the post-treatment bath to be used in the stabilization process according to the invention consists of a solution of the stabilizing compounds.
Aqueous solutions are preferred, but solutions in organic solvents or in solvent mixtures of water and organic solvents, such as aliphatic alcohols, dimethylformamide or the like, can also be used.
the pH of the solution can be raised or lowered, e.g. B. with KOH or with H2SO4.
the method according to the invention can be used in the broadest way for photographic silver images, regardless of the special type of production.
silver images can be made using conventional methods by developing and fixing an exposed photographic Materials were manufactured to be stabilized. These can be conventional halftone images, office copies or microfilms.
the method according to the invention can also be used to stabilize copies which have been produced by the silver salt diffusion method.
Finished silver images are subjected to the stabilization process according to the invention, i.e. Silver images obtained by photographic processing by developing an imagewise exposed photographic material containing silver halide, and the processing procedure after the development step may include a stabilizing treatment step in which the unexposed silver halide is completely or partially removed or converted to a non-photosensitive form .
Such a stabilizing treatment step can consist, for example, of subjecting the developed photographic recording material, which already contains the silver image but also residual silver halide, to a conventional fixing treatment, for example in a processing bath which contains an alkali metal thiosulfate or ammonium thiosulfate, the silver halide being soluble Siberian complex salt is dissolved out of the recording material.
a "stable" silver image is produced, the stability of which is based on the fact that essentially no light-sensitive silver halide is left in the unexposed areas, and which is referred to in the present context as a finished silver image.
the stabilizing method according to the invention is to be distinguished from the stabilizing treatment stage mentioned. While the latter serves to remove or convert any remaining silver halide, the stabilization process according to the invention is only used when the silver image produced contains essentially no more photosensitive silver halide.
the finished silver image which is subjected to the stabilization process according to the invention can, as already mentioned, also be a silver image which has been produced by the silver salt diffusion process. Such a silver image can have been produced in a separate image-receiving layer which may contain silver precipitation nuclei but no silver halide.
the aftertreatment bath according to the invention therefore does not need to contain any substances which serve to remove residual silver halide.
the aftertreatment bath according to the invention can contain further additives such as wetting agents, pH-modifying agents and antioxidants, e.g. contain an alkali metal sulfite or a hydroxylamine salt.
the aftertreatment bath according to the invention stabilizes the silver image produced by any method by photographic means, so that it is less sensitive to external influences during subsequent storage or storage, in particular to the effects of oxidizing gases.
the occurrence of this The stabilizing effect is also largely independent of the special type of photographic recording material used to produce the silver image, as long as it contains at least one light-sensitive silver halide emulsion layer and is developed by any black and white development process.
the light-sensitive silver halide emulsions used in the recording material can contain chloride, bromide and iodide or mixtures thereof as the halide.
the halide content of at least one layer consists of 0 to 12 mol% of iodide, 0 to 50 mol% of chloride and 50 to 100 mol% of bromide.
these are predominantly compact crystals that are, for example, cubic or octahedral or have transitional forms. They can be characterized in that they essentially have a thickness of more than 0.2 ⁇ m.
the average ratio of diameter to thickness is preferably less than 8: 1, it being true that the diameter of a grain is defined as the diameter of a circle with a circle content corresponding to the projected area of the grain.
all or individual emulsions can also have essentially tabular silver halide crystals in which the ratio of diameter to thickness is greater than 8: 1.
the emulsions can be monodisperse or heterodisperse emulsions, which preferably have an average grain size of 0.3 ⁇ m up to 1.2 ⁇ m.
the silver halide grains can have a layered grain structure.
hydrophilic film-forming agents are suitable as protective colloid or binder for the layers of the recording material, e.g. Proteins, especially gelatin. However, this can be replaced in whole or in part by other natural or synthetic binders. Casting aids and plasticizers can be used. Reference is made to Research Disclosure 17 643 (December 1978), in particular chapters IX, XI and XII.
the emulsions can be chemically and / or spectrally sensitized in the usual way; they can contain silver halide stabilizers, and the emulsion layers as well as other non-photosensitive layers can be hardened in the usual way with known hardening agents.
Suitable chemical sensitizers, spectral sensitizing dyes, stabilizers and curing agents are described, for example, in Research Disclosure 17643; Reference is made in particular to chapters III, IV, VI and X.
the recording materials subjected to the stabilization process according to the invention are exposed imagewise, it being possible to use ultraviolet, visible or infrared light or else high-energy radiation for the exposure.
This is followed by conventional processing to convert the exposed silver halide to image silver, to which end the recording material in the presence of a silver halide developer Compound, which can be contained in one of the layers of the recording material or in an aqueous treatment bath, is usually treated in an alkaline medium.
Inorganic or organic developer compounds can be used. Examples of this are hydroquinone, 3-pyrazolidone, aminophenol and their derivatives.
the development is followed by a fixing bath treatment, as a result of which the unexposed and undeveloped silver halide is released from the recording material.
the stabilizing method according to the invention can be used at any time after the development and generation of the silver image, it is most effective if it is used as the last treatment step before the black and white image is dried. This also means that preferably no further liquid treatment, in particular no washing, follows the stabilizing bath according to the invention. Rather, the stabilizing bath according to the invention is used as an aftertreatment or final bath.
the glass vessel was in a tempered water bath to adjust the temperature of 22-24 ° C inside the vessel. It was closed with an opaque glass plate.
the samples to be examined were irradiated through this glass plate by a fluorescent lamp (xenon lamp 22 watts) at a distance of approximately 20 cm. About 50 g of percarbonate were evenly added to the bottom of the glass jar. In each test, the dried test specimens were left in the glass jar until at least one of them had been severely attacked, based on the following evaluation criteria: no attack: no discernible discoloration minor attack: minor discoloration predominantly at low density moderate attack: moderate discoloration at low or high density severe attack: severe discoloration at low and high density until bleaching
