Abstract

602,160. Photographic emulsions. KODAK, Ltd. (Eastman Kodak Co., Trivelli, A.P.H., and Smith, W.F.). June 14, 1946, No. 16676/47. Divided out of 602,158. [Class 98 (ii)] A sensitive silver halide developing-out emulsion is stabilized by the incorporation of a complex halide of rhodium. The halide may have the formula R2RhX6 or R3RhX6, wherein R is H, an alkali metal, or ammonium, and X is a halogen atom (e.g. Cl or Br). Details of speed, gamma, and fog values with the addition of ammonium chlororhodate under different conditions are given. The use of ammonium chlororhodite is also referred to. The compound may be added before or during precipitation of the silver halide, before or during the first digestion (ripening), before or during the second digestion, or just before coating (before or after the addition of sensitizing dyes). A reducing agent (ascorbic acid) and sulphur sensitizers (e.g. thiourea, allyl isothiocyanate, thiosinamine, or a metal or ammonium thiocyanate, including one or more thiocyanates with a sulphur sensitizer other than a thiocyanate) may also be added. Both the rhodium compound and the sulphur sensitizer are preferably present during the second digestion, and the pH of the emulsion is preferably adjusted to between 5 and 7. The emulsions may be sensitized with any of the usual dyes, e.g. erythrosin, Congo Red, monomethine-, trimethine-, pentamethine-, or heptomethine. cyanines, merocyanines, hemicyanines, or hemioxonols, and supersensitizing mixtures may be used. Hardening agents, setting agents, or stabilizing agents may also be added. Specifications 450,958, 479,970, 515,145, and 517,769 are referred to.
