  • Metal particle data recording medium having enhanced elastic modulus
    Publication number: 20040112472
    Abstract: A surface treated magnetic pigment particle suitable for use with a binder in an information-recording layer of magnetic recording media. The surface treated magnetic pigment particle is a magnetic pigment particle with at least first and second surface treatment agents adsorbed onto the surface of the magnetic pigment particle. The first surface treatment agent has the formula E—X1—A1 wherein E is an electron withdrawing group which is not reactive with the binder, A1 is an acidic group, and X1 is a divalent moiety. The second surface treatment agent has the formula F—X2—A2 wherein F is a functional group reactive with the binder, A2 is an acidic group, and X2 is a divalent C1-4 alkyl moiety.
