摘要：
A magnetic recording medium comprising a nonmagnetic support having provided thereon a magnetic layer comprising ferromagnetic fine powder dispersed in a binder, wherein said magnetic layer contains crosslinked resin fine particles to which a polymer containing an --OH group has been bonded, and an isocyanate compound, said polymer containing an --OH group having an affinity toward said binder and said --OH group reacting with said isocyanate compound to form a chemical bond with said binder.
