Abstract
1,027,146. Photographic silver halide emulsions. AGFA A.G. Aug. 30, 1963 [Sept. 1,1962], No. 34423/63. Heading G2C. The invention relates to a process of preparing a photographic emulsion comprising grains composed of a silver halide core which either has its surface modified and is then coated with a shell of the same or a different silver halide, or is coated directly with a shell of a different silver halide. The emulsions are prepared by adding to an aqueous gelatine solution an aqueous solution of a water-soluble silver salt and an aqueous solution of a water-soluble alkali metal halide in such a manner that the silver ion concentration is kept between 1 x 10-6 and 1 x 10<SP>-10</SP> moles per litre in order to precipitate a maximum number of silver halide nuclei. The surface of the nuclei are then modified, if desired, and the outer shell of silver halide is formed by continuing the addition of the silver salt solution and the same or different alkali-metal halide solution. The surface of the silver halide core may be modified by one of the following treatments,- (i) Reduction of silver ions in the surface to silver atoms by means of a reducing agent such as hydrazine and its derivatives, polyhydroxy benzene compounds, ascorbic acid or formaldehyde. (ii) conversion of the surface silver halide to silver sulphide by means of sodium thiosulphate, sodium sulphide or thiourea. (iii) Incorporating gold, thallium, copper , palladium, iridium or platinum into the surface by treatment with aqueous solutions of their compounds. (iv) Exposing the emulsion in the liquid state to actinic light to form silver atoms in the surface of the core. (v) Treatment with an aqueous solution of a silver halide solvent such as a thiocyanate to cause etching of the surface.
