Abstract
An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T.sub.g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.
