Magnetic recording media comprising a back coat containing a mixture of a thermosetting resin and photosetting resin and a process therefor |
摘要 |
A magnetic recording medium comprising a non-magnetic substrate, a magnetic layer formed at one surface of the substrate, and a back coat layer formed at the other surface of the substrate wherein the back coat layer contains a thermosetting resin and a photosetting resin and its light transmittance is at least 1%. A process for producing a magnetic recording medium which comprises the steps of applying a back coat layer containing a thermosetting resin and a photosetting resin and having a light transmittance of at least 1% to one surface of a non-magnetic substrate; irradiating the back coat layer with a light from both surfaces to carry out photosetting; applying a magnetic layer to the other surface of the non-magnetic substrate; winding the double-coated substrate in the form of a roll; and thermosetting the back coat layer. The magnetic recording media having excellent characteristics can be easily obtained without requiring any complicated apparatus.
