In the production of magnetic recording media by applying a suspension of ferromagnetic powder in a solution of a binder on to a backing, the binder comprises a mixture of a polyamide and a monomer having at least two double bonds, which is polymerized in situ by irradiation, heat, or ozone. The monomer is preferably acrylic, and may be N,N 1 -methylene, ethylene, trimethylene, hexamethylene, or p,p-diaminocyclohexylmethane, -bis-acrylamide or -methacrylamide; or an acrylate or methacrylate of glycol, propylene glycol, butanediol, pentanediol, hexanediol, glycerol, trimethylol propane, pentaerythritol, or cyclic polyols. Suitable polyamides, solvents, initiators, plasticizers, and bases are listed. Polymerization may be effected (before, during, or after drying) with I.R., visible, or U.V. radiation, heated rollers, dryers, α, #, or γ rays, passage of O 3 produced by electric discharge. Monomers having one double bond may also be incorporated with the binder. The wt. ratio of powder: binder may be 2: 1 to 6: 1, and the powder may be Fe 3 O 4 , acicular γ- Fe 2 O 3 , or Fe.
