Abstract

931,293. Fixing photographic silver images. KODAK Ltd. Nov. 11, 1960 [Nov. 12, 1959], No. 38347/59. Class 98 (2). Photographic silver images are stabilized (i.e. fixed, but not washed) in the presence of, or the stabilized image is treated with, a thiol compound of the general formula wherein X represents a vinylene or substituted vinylene group, a -CR<SP>1</SP>=N- group (R<SP>1</SP> being H, alkyl or carboxyalkyl) or a sulphur or oxygen atom, Y and Z are hydrogen atoms or monovalent substituents or together complete a benzene ring which may carry substituents, and R is hydrogen or an alkyl group. The thiol compound may be added to the silver halide emulsion or to the developer or fixer, or it may be used in a separate bath. The fixer may be an alkali metal or ammonium thiocyanate, an alkali metal or ammonium thiosulphate, a thiourea or a thioglycollic acid. The emulsion layer may contain a developing agent and be developed in alkali which may contain the thiol compound. Specifications 636,981, 667,206, 693,632, 851,815 and 851,816 are referred to.
