Magnetic tape |
| abstract |
Magnetic tape having extraordinary performance characteristics and formed with a sparingly-crosslinked, polyurethane-based polymer binder system as a matrix for magnetic particles. The binder system is characterized by toughness of at least 150 in-lbs. per in3, and the ability to withstand video tape-Test for over an hour before any substantial tape degradation occurs. Magnetic coatings prepared according to the invention comprise a binder system of at least 50% of a tough polyurethane. |
