Abstract
967,624. Photographic emulsions. GEVAERT PHOTO-PRODUCTEN N.V. Sept. 21, 1960, No.32504/60. Heading G2C. A photographic gelatino-silver halide aqueous dispersion is precipitated by adding an aqueous solution of a polyvinyl sulphonic acid or salt thereof and lowering the pH. The supernatant liquid is decanted off, and the precipitate is washed and redispersed in water at 30-45‹C. with the addition of alkali. Additional gelatin may then-be added if desired. Specifications 649,545, 649,546, 861,984 and 932, 620 are referred to.
