Abstract

PURPOSE: To obtain the magnetic recording medium less in dropout due to the attachment of dust, through the prevention of charge, by forming the magnetic substance layer by coating the magnetic paint including alcohol as solvent or diluent composition on the base.
CONSTITUTION: The magnetic paint is prepared by mixing (A) the fatty alcohol 5 or lower in the carbon number such as methyl alcohol, ethyl alcohol, isopropyl alcohol and butyl alcohol, used 1'30wt% in the total solvent as the solvent or diluent, (B) solvent such as methyl ethyl ketone and toluene, (C) coupling agent such as polyvinyl chloride copolymer and polyvinychloride-vinylidene copolymer, (D) and magnetic powder such as γ-Fe2O3, Fe3O4, GrO2. Next, by forming the magnetic layer through the coating of this magnetic paint on the substance such as polyester film, the objective magnetic recording medium can be obtained.
