Abstract

1,156,193. Preparing photographic silver halide dispersions. EASTMAN KODAK CO. Oct. 20, 1966 [Oct.21, 1965], No.46915/66. Heading G2C. A photographic silver halide dispersion is made by simultaneously running aqueous silver nitrate and aqueous halide solution (e.g. KBr and KI) into agitated aqueous peptizer solution (e.g. gelatine or a derivative thereof) so that the pAg of the precipitation medium is from 8À6 to 9À2, and maintaining the pH of the precipitation medium at not more than 4À0 (e.g. by adding sulphuric acid). The silver halide grains obtained have predominantly cubic (1, 0, 0) faces. The emulsions obtained from the above dispersions may be sulphur or noble metal sensitized and may be optically sensitized preferably with cyanine dyes, some of which are specified.
