Magnetic recording medium

摘要

A magnetic recording medium comprising a support having coated thereon a magnetic layer is disclosed. The magnetic layer contains, as a binder, a composition cured with electron beam comprising (a) at least one of vinyl chloride-vinyl acetate type resins containing 5x10-5 to 1.7x10-3 equivalents of a carboxyl group per gram of the polymer and introcellulose resins, (b) a urethane resin and (c) at least one compound selected from the group consisting of aromatic or alicyclic compounds containing at least two vinyl linkages in the molecule and acryloyl-modified polyisocyanate compounds. The magnetic recording medium has excellent electromagnetic properties and durability.
