Definitions
- This invention relates to single-powder photographic developers, and more particularly to a method of packaging and stabilizing the singlepowder mixture to prevent disadvantageous interaction between the organic developer compartment and the basic component of the singlepowder mixture.
- Single-powder developer mixtures may contain an organic developer component or mixtures of such components, including monomethylpara-- aminophenol sulfiate (elon or metol), hydroquinone, p-aminophenol hydrochloride, p-aminophenol sulfate, pyrogallol, parahydroxyphenyl glycine, catechol, diaminophenol hydrochloride and others, with an alkali component, a stabilizing component, an oxidizing preventer and an anti-fogging component.
- the alkali component may be the stable hydrate of an alkali carbonate, a desiccated alkali carbonate, an alkali metaborate, or an alkali sulfite.
- the stable alkali carbonate monohydrate is preferred.
- the oxidation preventing component may be an alkali sulfite, and the anti-fogging component may be potassium bromide or iodide.
- Stabilizing components for such a single-powder developer are disclosed in Patent 2,384,592 of September 11, 1945, and include maleic anhydride, salicylic acid, alkali metabisulfite, benzoic anhydride, orthobenzoic sulfamide, phthalamide and phthalic anhydride. The latter has outstanding stabilizing properties in the presence of either sodium carbonate or borax and has been employed considerably more than the other stabilizers mentioned in that patent.
- phthalic anhydride While the stabilizing effect of the phthalic anhydride is very good, it has been employed most successfully in developer compositions having as the alkali component either sodium carbonate or sodium sulfite, or mixtures thereof. Less success has been attained in the case of the important class of developers containing sodium metaborate as the alkali ingredient. Also, the presence of phthalic anhydride in the single-powder developer involves other considerations which are not too desirable.
- phthalic anhydride is slowly soluble in water. Furthermore, it is impossible to employ it in the presence of benzotriazole, the latter being a desirable component of certain developer mixtures.
- benzotriazole the greatest disadvantage of employing phthalic anhydride in single-powder developer mixtures, which contain alkali carbonates and sulfite, is that phthalic anh dride may react, due in part to temperature eiiects, with these basic substances and form gas under sufiicient pressure to distend the hermetically sealed can in which the developer powder is packaged, and often cause a portion or" the powder to be ejected with some violence as the package is opened.
- An object, therefore, of the present invention is a novel method of stabilizing single-powder photographic developers.
- Another object of this invention is a novel method of packaging and a novel package for single-powder photographic developers.
- the same beneficial stabilizing effect may be achieved by enclosing an amount of the stabilizer in a relatively small permeable bag, and placing the permeable bag Within the hermetically sealed container in which the ingredients comprising the single-powder developer are packaged.
- the bag may be made from cloth, the meshes of which are smaller than the crystals of the stabilizer, or other permeable material such as paper.
- An amount of stabilizer up to of the total weight of the other constituents may be employed eifectively. No particular advantage is found when a larger amount is employed.
- Example 1 A thoroughly mixed single-powder photographic developer composition comprising:
- Example 2 A thoroughly mixed single-powder photographic developer composition comprising:
- Example 3 A thoroughly mixed single-powder photographic developer composition comprising:
- Example 4 A homogeneously mixed single-powder photographic developer composition comprising:
- compositions of the above examples should be dissolved in water to make one liter of solution.
- FIG. 1 An elevational view in section of a container comprising a body I0 and a tight fitting cover II.
- a single-powder photographic developer is shown at l2.
- a closed small mesh cloth bag [3 filled with the selected stabilizer I4 is positioned within the can. As shown in the drawing the bag may be positioned more or less in the middle of the 4D developer mixture.
- Example 6 The formula of Example 5 was stabilized in the same manner except 2 grams of metaboric acid were placed in the tea bag. Similar results were obtained as in Example 5.
- Example 7 The formula of Example 5 was placed in the sealed can and protected by a combination of 0.2 gram phthalic anhydride mixed with 1.8 grams of boric anhydride in a tea bag. The protected sample was of good whiteness after 6 days.
- the method of stabilizing a single-powder photographic developer composition containing an organic silver halide developer and a photographically compatible basic ingredient selected from the group consisting of alkali sulfites and carbonates which comprises packaging the developer composition in a closed container in which is positioned a closed permeable bag containing a stabilizer selected from the group consisting of boric anhydride, metaboric acid, and mixtures of boric anhydride with phthalic anhydride and mixtures of metaboric acid and phthalic anhydride.
- the method of stabilizin a single-powder photographic developer composition containing an organic silver halide developer, an alkali carbonate, and an alkali sulfite which comprises packaging the developer composition in a closed container in which is positioned a closed permeable bag containing boric anhydride.
- the method of stabilizing a single-powder photographic developer composition containing an organic silver halide developer, an anhydrous alkali sulfite, and an alkali carbonate which comprises packaging the developer composition in a closed container in which is positioned a closed permeable bag containing metaboric acid.
- the method of stabilizing a single-powder photographic developer composition containing monomethyl p-ainino phenol sulfate, hydroquinone, anhydrous sodium sulfite, sodium carbonate monohydrate and potassium bromide which comprises packaging the developer com" position in a closed container in which is positioned a closed permeable bag containing substantially equal amounts of boric anhydride and phthalic anhydride.
- the method of stabilizing a single-powder photographic developer composition containing monomethyl p-amino phenol sulfate, hydroquinone, anhydrous sodium sulfite, sodium carbonate and potassium bromide which comprises packaging the developer composition in a closed container in which is positioned a closed permeable bag containing metaboric acid and phthalic anhydride.
