摘要： PURPOSE:To improve durability, magnetic characteristics, electromagnetic conversion characteristic, etc. by using a vinyl chloride copolymer having double bonds sensitive to electron rays and a ternary amine salt of a sulfonic acid or ternary amine salt of sulfate as a polar group in the molecule for a binder constituting a magnetic layer. CONSTITUTION:The vinyl copolymer having the double bonds sensitive to electron rays and further having the ternary amine salt of the sulfonic acid and the ternary amine salt of sulfate as the polar group in the molecule is used as the binder for the magnetic material, by which the high affinity to magnetic powder is exhibited and the good dispersibility is obtd. even with the ultrafinely pulverized magnetic powder or the magnetic powder having a large quantity of magnetization. The durability and surface characteristic of the resulted magnetic recording medium are improved and the electromagnetic conversion characteristic is extremely highly improved as well. Since the binder has the double bonds sensitive to electron rays in the molecule, the magnetic coated film is easily cured by the irradiation of electron rays and the process for production is extremely simplified; in addition, the pot life and solidification of the paint are improved and thus there are many advantages in the process.

SOLUTION: The pulverulent body has an aspect ratio of more than 1, preferably in the range of 5-50. A reactive group is a radically polymerizable one and a reactive monomer or oligomer may be radically polymerizable one. The pulverulent body is of the shape of a flake, of which thickness is preferably 0.1-2 μm. In addition, an average particle size is preferably 0.1-100 μm on the basis of the volume. A blend ratio (a weight ratio) of the organopolysiloxane to the monomer or oligomer is 0.1/99.0 to 50/50. The polymerization reaction is carried out by an emulsion-, solution-, or bulk-polymeization by using a radical initiator (e.g. benzoyl peroxide) in accordance with the usual process.
