Abstract
1,236,733. Silver sulphide. KODAK Ltd. 21 April, 1970 [24 Jan., 1969], No. 4130/69. Heading C1A. [Also in Division G2] A composition for converting silver to silver sulphide comprises an aqueous solution of a water-soluble sulphide, e.g. sodium sulphide, sodium m-nitrobenzene sulphonate, and sulphite ions, e.g. in the form of sodium sulphite. The composition preferably contains 0À074 to 0À59 moles of sulphite per litre and can contain 10 to 80 g. of sodium sulphite per litre.
