Binding composition, useful in magnetic recording materials, comprises radical-polymerized block copolymer and magnetic or magnetizable pigment

摘要

Binding composition contains, at least, a block copolymer (BC), produced by radical polymerization and containing at least two blocks of different monomer composition, and at least one magnetic or magnetizable pigment (P). Independent claims are also included for the following: (a) preparation of the binding composition; and (b) magnetic recording medium containing the new binding composition.
