Abstract
In an electrosensitive recording member having a surface recording layer wherein the surface recording layer comprises a resin binder, a pigment dispersed through said binder and an effective amount of at least one particulate smudge inhibitor to inhibit the formation of smudge produced by the action of an electronic recording means on the surface of the recording member. The smudge inhibitor is a divalent metal palmitate or stearate, or N,N'-ethylene-bis stearamide, or mixtures thereof. The particulate smudge inhibitor is either incorporated into and dispersed throughout the surface recording layer or applied to the surface recording layer as a separate coating thereon.
Claims16
In a front grounding or back grounding electrosensitive recording medium having a surface recording layer, said surface recording layer comprising a resin binder, a pigment dispersed throughout said binder and an effective amount of at least one particulate smudge inhibitor selected from the group consisting of divalent metal stearates, divalent metal palmitates, N,N'-ethylene bis-stearamide, and mixtures thereof, that forms at least a part of the surface of said recording layer so as to inhibit the formation of smudge produced by the destructive action of an electronic recording means to produce the desired recording on the surface of the recording medium during a recording operation.
A method for inhibiting the formation of smudge on the surface of a front grounding or back grounding electrosensitive recording medium comprising incorporating at least one particulate smudge inhibitor selected from the group consisting of divalent metal stearates, divalent metal palmitates, N,N'-ethylene bis-stearamide and mixtures thereof, onto the surface of said electrosensitive recording medium.
