Abstract: 1420692 Magnetic recording tape BADISCHE ANILIN- & SODA-FABRIK AG 27 April 1973 [28 April 1972] 20074/73 Heading B2E A thermostable rigid base plated with a firmly adhering film of ferromagnetic metallic material containing cobalt has applied thereto a layer from a solution of at least one film-forming organic coating resin in a volatile solvent, the layer in dried and unbaked condition being not more than 3000A thick, and drying and baking being effected at 200-300‹C for 1-15 hours. Specified resins are polycarbonates, polyurethanes, acrylic polymers, polyglycidal ethers and esters cured with polyamines and polyaminoamides and phenol-amine resins. The ferromagnetic metal may be Co-P, Co-B, Co- Ni, Co-Fe-Ni alloys. Ketones, ethers and hydrocarbons are typical volatile solvents.

Abstract: Magnetic recording media comprising a non-magnetic base and, applied thereto, a firmly adhering magnetic coating based on a finely divided magnetic pigment dispersed in a binder which contains at least 50 percent by weight of a special polyurethane elastomer, namely a thermoplastic polyurethane which is soluble in tetrahydrofuran, is free from isocyanate groups and has been manufactured from (A) 1 mole of a hydroxyl-containing polyester having a molecular weight of from 700 to 2,500, (B) from 0.3 to 3 moles of a linear aliphatic diol of 2 to 10 carbon atoms, (C) from 0.05 to 0.4 mole of a triol of 3 to 10 carbon atoms, and (D) from 1.35 to 4.7 moles of a diisocyanate of 6 to 30 carbon atoms, the amount of NCO groups being approximately equivalent to the amount of OH groups of the sum of components (A) to (C).

Abstract: The polymeric material is used with a solvent which is partly compatible and partly incompatible with water so that when it is dispersed with water it develops a capsule wall which can be chemically cross-linked. Microcapsules of size 2-20 mu are formed which can easily be applied to a paper, to give typing copying paper without interleaved carbon sheets, which can be stored for long periods and at high temps. without loss of the encapsulated colourant fluid.

Abstract: Magnetic recording media comprise a non-magnetic base which is provided with a magnetic layer which consists of a dispersion of an anisotropic magnetic material in an organic binder which consists essentially of an OH-containing polyurea-urethane binder crosslinked with polyisocyanate. The OH-containing polyurea-urethane is obtained by reacting a polydiol, a diol and a primary or secondary aminoalcohol, and if appropriate a triol, with a diisocyanate.
