Abstract

1334397 Gelatine compositions FILMFABRIK WOLFEN VEB 26 Jan 1971 3194/71 Heading C3H [Also in Division G2] A gelatine composition comprises a mixture of a gelatine having an isoelectric point from 4À5 to 5À2 with from 10% to 100% by weight, calculated on that gelatine, of a gelatine having an isoelectric point from 6À0 to 9À0. One or both of the gelatines may be de-ionized and the mixture may be made by mixing the components in aqueous solution. The mixture may be used as a binder in photographic emulsions or auxiliary layers.
