Abstract Translated from German Zur Herstellung mattierter äußerer Schichten photographischer Silberhalogenidaufzeichnungsmaterialien werden in der wässrigen Lösung eines hydrophilen Kolloids Teilchen eines Suspensions-Copolymerisats aus Maleinsäureanhydrid und einem C2 - Ca Monoolefin dispergiert. Die Dispersion wird auf eine oder beide Oberflächen des photographischen Aufzeichnungsmaterials aufgetragen und getrocknet. To produce matt outer layers of photographic silver halide recording materials, particles of a suspension copolymer of maleic anhydride and a C2-Ca monoolefin are dispersed in the aqueous solution of a hydrophilic colloid.
