[Class 98 (ii)] The tendency to aerial oxidation of a photographic developing solution, wherein the developing agent or agents is or are other than ascorbic acid and which is adapted for developing an image in a silver halide emulsion, is reduced by incorporating in such solution an ascorbic acid or isoascorbic acid or a salt thereof. The developer may be a colour developer used for producing a coloured image in an emulsion containing a colour coupler added directly thereto before casting or incorporated in a separate medium dispersed as particles in the emulsion. The developer may also be a tanning developer, which may comprise an alkaline solution of catechol or pyrogallol. Laevo-ascorbic and dextro-iso-ascorbic acid or their alkali metal, e.g. sodium, salts may be used. Some developing solutions containing sodium sulphite may be improved by the addition of ascorbic acid. The use of ascorbic acid as a developing agent itself is referred to. The amount of ascorbic acid used according to the invention is less than the total amount of other developing agents, preferably not more than 50 per-cent, e.g. 10 to 25 per cent. In colour development, the minimum amount of ascorbic acid is used. The developer may be a diethyl-p-phenylenediamine developer used for developing an exposed three-layer material containing colour couplers. In example 1, a colour developer contains diethyl-p-phenylenediamine hydrochloride, sodium sulphite, sodium carbonate, 1 - phenyl - 3 - methyl - 5 - pyrazolone, acetone, and ascorbic acid. In example 2, a black-and-white developer comprises hydroquinone, potassium metabisulphite, potassium bromide, caustic potash, and ascorbic acid. In example 3, a black-and-white developer comprises metol, sodium sulphite, hydroquinone, sodium carbonate, potassium bromide, and ascorbic acid. In example 4, a developer comprises pyrocatechol, sodium sulphite, sodium hydroxide, potassium bromide, formaldehyde, and the sodium salt of isoascorbic acid. In example 5, a tanning developer comprises sodium sulphate, pyrocatechol, potassium bromide, laevo-ascorbic acid, and sodium hydroxide. In example 6, a high-energy developer comprises catechol, monomethyl-paminophenol sulphate, sodium bisulphite, sodium sulphate, 6-nitrobenzimidazole nitrate; sodium carbonate, sodium hydroxide, and the sodium salt of isoascorbic acid.
