ABSTRACT:
A photographic binder prepared by heating a mixed aqueous solution of styrene-maleic anhydride copolymer, isobutylene-maleic anhydride copolymer and polyvinyl alcohol in acidic state makes it possible to coat a photographic coating liquid for forming photographic layers in the same manner as in the case of using gelatin and furthermore gives excellent physical properties to the resultant photographic layers.
