| titleOfInvention |
Magnetic recording medium having a binder system including a polyurethane polymer having both phosphonate and quaternary ammonium pendant groups |
| abstract |
A magnetic recording medium comprising a magnetic layer provided upon a major surface of a substrate, wherein the magnetic layer includes a magnetic pigment, and a polymeric binder system containing a polyurethane having (1) a plurality of pendant phosphonate ester groups effective for promoting wetting of the magnetic pigment by the polymeric binder system, and (2) at least one quaternary ammonium group effective for promoting wetting of the magnetic pigment by the polymeric binder system. |
