Abstract
A photographic sheet element comprising a film support, at least one light-sensitive layer having a hydrophilic binder on a first side of the support, the thickness of the at least one light-sensitive layer and other layers on the first side of the support being T.sub.E, on the opposite side of the support, a transparent magnetic recording layer comprising ferromagnetic particles in a hydrophilic colloid, the thickness of the transparent magnetic recording layer being T.sub.M, intermediate, the transparent magnetic recording layer and the support, a hydrophilic colloid control layer, the thickness of the control layer being T.sub.C, the relative thickness of the layers being represented by the formula: ##EQU1## where 0<X<10.
