Title (EN) MAGNETIC RECORDING MEDIUM
(FR) SUPPORT D"ENREGISTREMENT MAGNETIQUE
Abstract: front page image
(EN)A magnetic recording medium useful for magnetic tape, magnetic cords, magnetic discs, etc., which is prepared by using (A) a radiation-hardenable compound having a molecular weight of not less than 5000, preferably not less than 8000, and having two or more unsaturated double bonds, (B) a radiation-hardenable compound having a molecular weight of not less than 400 and less than 5000, preferably 600 to 3000, and having one or more unsaturated double bonds, and (C) a radiation-hardenable compound having a molecular weight of less than 400 and having one or more unsaturated double bonds, coating a magnetic paint on a base material, the magnetic paint primarily containing magnetic particles prepared by compounding (A) and (B), or (A), (B) and (C), and a solvent, and, after preliminary drying, irradiating it.
(FR)Un support d"enregistrement magnetique utile pour une bande magnetique, des cordes magnetiques, des disques magnetiques etc, est prepare en utilisant (A) un compose durcissable par irradiation ayant un poids moleculaire au moins egal a 5000, de preference au moins egal a8000, et ayant deux ou plusieurs doubles liaisons non saturees, (B) un compose durcissable par irradiation ayant un poids moleculaire au moins egal a 400 et inferieur a 5000, de preference entre 600 et 3000, et ayant une ou plusieurs doubles liaisons non saturees, et (C) un compose durcissable par irradiation ayant un poids moleculaire inferieur a 400 et ayant une ou plusieurs doubles liaisons non saturees, en revetant un materiau de base d"une peinture magnetique, la peinture magnetique contenant essentiellement des particules magnetiques preparees par compoundage de (A) et (B), ou (A), (B) et (C), et un solvant, et, apres sechage preliminaire, en l"irradiant.
