Photographic element having a transparent magnetic layer and a process of preparing the same

摘要

A photographic element comprising a support, having at least a silver halide light-sensitive layer and a transparent magnetic recording layer, the transparent magnetic layer having ferromagnetic particles in a polymeric binder, ferromagnetic particles having a size of at least 30 m2/gm and being present in the transparent magnetic layer in a coverage of from about 1x10-11 mg/ mu m3 to about 1x10-10 mg/ mu m3, the polymeric binder containing up to about 25 weight percent based on the weight of the polymeric binder of a dispersant-cobinder comprising a poly(C2-4-alkyleneimine) carrying at least two mono- or poly(carbonyl-C1-7-alkyleneoxy) groups.
