Abstract

A room temperature curable magnetic ink, which includes CrO(2) particle is made from urethane, a polyfunctional isocyanate crosslinking agent and CrO(2) particles. This ink is then used to coat a non-magnetic substrate to form magnetic recording media. Preferably, the CrO(2) particles, prior to mixing, are not stabilized in that their magnetic properties would be subject to change with humidity were it not for the following procedure. Stabilized particles can be used if desired.
