ABSTRACT:
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 m.sup.2 /gm and being present in the transparent magnetic layer in a coverage of from about 1.times.10.sup.-11 mg/.mu.m.sup.3 to about 1.times.10.sup.-10 mg/.mu.m.sup.3, 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(C.sub.2-4 -alkyleneimine) carrying at least two mono- or poly(carbonyl-C.sub.1-7 -alkyleneoxy) groups.
