Abstract

259,538. I. G. Farbenindustrie Akt.- Ges., (Assignees of Akt.-Ges. f³r Anilin- Fabrikation). Oct. 7, 1925, [Convention date]. Drawings, to Specification. Electric endosmose.-The sensitivity of silver halide emulsions is increased by the addition to the emulsion or ingredients thereof, of substances which collect at the electrodes on the electrodialysis of proteins, e.g. gelatin or glue. These electrodialytically separated extracts are neutralized by alkali or acid means, and dried by evaporation before use. Specifications 235,209 and 235,210, [both in Class 98 (ii), Photographic processes &c.], are referred to.
