  • Patent number: 4339504
    Abstract: An improved multilayer electrosensitive recording medium is disclosed comprising a low density polyethylene in one or more of the layers. By using low density polyethylene as a binder in one or more of the layers of an electrosensitive recording medium, the problem of burn-off odor is reduced or eliminated. Pigments such as carbon black and modifiers such as surfactants may also be added to the particular layer.Particular embodiments are disclosed in which the polyethylene layer or layers are formed by the application of a dispersion of low density polyethylene. The dispersion mixture also includes modifying agents and pigments. After coating the dispersion the solvent is evaporated off and the coating is warmed so that any remaining solvent may be evaporated and the coating particles may form a layer.
