Abstract
993, 098. Preparing light developable silver halide emulsions. E. I. DU PONT DE NEMOURS & CO. Oct. 23, 1963 [Oct.25, 1962], No. 41887/63. Heading G2C. Light devoloble, direct writing, silver halide emulsions are made by (1) admixing aqueous silver nitrate and from 0.33 to 10 mole percent, bared on the silver, of a water-soluble plumbous salt e.g. the nitrate with an acidified aqueous solution of a water-soluble halide containing a waterpermeable organic colloid binding agent (2) ripening the resulting silver halide emulsion and (3) digesting the emulsion and before or during the digestion or before coating, incorporating with the silver halide emulsion, based on the silver (a) 0- 120 mole percent of a water-soluble inorganic bromide e.g. potassium bromide (b) 0-5 mole percent of a water-soluble plumbous salt and either (c) 5-50 mole percent of a water-soluble stannous salt e.g. the chloride or (d) 30-350 mole percent of sodium nitrite. An optical sensitising dye e.g. 3, 31-diethyl-5, 5<SP>1</SP> -diphenyl-9-methyl-oxacarbocyanine iodide may be added to the silver halide before digestion. Specifications 542,704, 600,023, 718,422, 731,626, 762,019, 786,176, 788,343, 877,841, 931,636 and 967,768 are referred to.
