Abstract: Magnetic recording media are produced by preparing a dispersion consisting of finely divided magnetic material, a dispersant, the conventional additives and a solution or a dispersion of a polymeric binder, applying the dispersion in the form of a layer onto a non-magnetizable base, orienting the anisotropic magnetic material by means of a magnetic field and drying the applied layer, by a process in which the dispersant employed is obtained by reacting A. from 70 to 95 parts by weight of a reaction product of I. from 0.5 to 1.5 moles of an oxoalcohol of 6 to 20 carbon atoms, II. from 6 to 18 moles of ethylene oxide and III. from 2 to 10 moles of propylene oxide, with B. from 5 to 30 parts by weight of a polyphosphoric acid having a P2O5 content of from 80 to 88%.
