Definitions
- This invention relates to single-powder photographic developers and more particularly to a method of stabilizing hydrates of sodium metaborate, and to single-powder photographic develolJer compositions containing such stabilized salt.
- Various single-powder photographic developers have been known heretofore. They may contain an organic silver halide developer component or mixtures of such components, including monomethyl p-aminophenol sulfate (Elon or metol), hydroquinone, p-aminophenol hydrochloride, p-aminophenol sulfate, pyrogallol, phydroxy phenyl glycine, catechol, diaminophenol hydrochloride, and others, with an alkali component, a stabilizing component,an oxidation inhibitor, a sequestering agent, and an antifogging component.
- an organic silver halide developer component or mixtures of such components, including monomethyl p-aminophenol sulfate (Elon or metol), hydroquinone, p-aminophenol hydrochloride, p-aminophenol sulfate, pyrogallol, phydroxy phenyl glycine, catechol, diamin
- the alkali component may be the stable hydrate of an alkali carbonate, a desiccated alkali carbonate, an alkalimetaborate, or an alkali sulfite. Generally the stable alkali carbonate monohydrate is preferred.
- the oxidation-preventing component may be an alkali sulfite, and the antifoggant may be potassium bromide, potassium iodide, or an organic compound.
- Stabilizing components for such a single-powder developer are disclosed in Patent 2,384,592 of September 11, 1945, and include maleic anhydride, salicyclic acid, alkali metabisulfite, benzoic anhydride, orthobenzoic sulfimide, p-hthal- 1 imide, 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 the patent.
- the stabilizing efiect 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.
- boric anhydride is disclosed as an improved stabilizer for such sin- .gle powders as described above. In certain respects boric anhydride is superior to phthalic anhydride in stabilizing such powders.
- Another object of the invention is to prepare 7 more stable hydrates of sodium metaborate than is possible by other methods.
- Still another object is to stabilize hydrates of sodium metaborate by a method which does not substantially lessen their alkalinity.
- Example 4 'KTheheatdtreatment be accomplished at a low temperature for a long period of time (Example 4) or by treatment at a higher temperature for a shorter time (Examples 1, 2, and 3). In the extreme case (Example this heat treatment is accompanied by appreciable dehydra tion which further improves the stability of the mixture.
- Suitable stabilizing compounds include those mentioned previously in this specification and of these, boric anhydride, metaboric acid and phthalic anhydride have been found to be most successful although the other stabilizing compounds are satisfactory.
- boron oxide hydrated to any degree intermediate to boric anhydride and metaboric acid is suitable.
- Sodium metaborate tetrahydrate so treated can be advantageously incorporated in singlepowder formulas which do not show any indication that a reaction has taken place between the components of the mixture even after prolonged exposure to relatively high temperatures.
- the total amount of protectant used is generally less than that used in cases where treatment is by another method.
- Example 1 Boric anhydride was added to sodium metaborate tetrahydrate in a concentration of per cent and the mixture heated for 4 hours at 70 C. This mixture was packed in a formula consisting of:
- This single powder did not discolor or otherwise deteriorate when stored.
- Example 2 Phthalic anhydride was added to sodium metaborate tetrahydrate in a concentration of 2.5 per cent and the mixture heated for 4 hours at 70 C. This mixture was packed in a formula consisting of:
- Example 3 4 Sodium sulfite 22.5 Sodium metaborate tetrahydrate 10 per 7 cent metaboric acid 39.6 Potassium bromide 2.0
- This single powder d d not discolor or otherwise deteriorate on storage.
- Example 4 Phthalic anhydride was added to sodium metaborate tetrahydrate in a concentration of 10 per 'cent and the mixture was heated at 40 C. for 30 days. The mixture was packed in a formula consisting of:
- This single powder did not discolor or otherwise deteriorate when stored for three weeks at F.
- the method of stabilizing hydrates of sodium metaborate which comprises mixing powder like particles thereof with 2.5 to 10% by weight of a finely divided stabilizer selected from the group consisting of phthalic anhydride, boric anhydride, and metaboric acid and heating the mixture for approximately 4 hours at 70 C.
