ABSTRACT:
Magnetic recording carriers having improved mechanical properties are obtained by using, as dispersing agents, compounds corresponding to the general formula ##STR1## which are attached to the magnetic pigment by their SO.sub.3 H group and which have reactive groups by which they are linked to the reactive groups of the polymeric binder through a difunctional or higher functional isocyanate.
