Abstract: Provided is an ink jet ink comprised of water, a pigment, a polymeric electrolyte, preferably a sodium, potassium or lithium salt of a polymeric carboxylic acid, a polyhydric alcohol and a stearate, preferably aluminum stearate. The presence of the stearate, particularly in combination with the polymeric electrolyte, provides one with an ink jet ink which upon printing makes a perfectly round dot located only on the surface of the paper. The image also dries very quickly, is of high density and is waterfast. Printing problems are also avoided, such as plugging.The process for preparing the foregoing ink jet ink comprises comminuting a formulation containing the components followed by a separation step. The separation step is important to provide a stable dispersion of the ink formulation.

Abstract: Novel electrographically produced products are disclosed which include large format posters, billboards and the like produced by a process employing a novel electrographic element which includes a base, a release layer and a combined transparent dielectric and adhesive layer which is substantially tack-free, at ambient pressure and temperature. The new product is made by an imaging process involving:A) producing a toned image layer on the surface of the electrographic element and B) pressure laminating a receptor substrate at an elevated temperature to the toned image layer to form the completed electrographic image. The base and release layer may be stripped from the dielectric/adhesive layer which then serves to protect the transferred, toned, electrographically generated image from abrasion and environmental contaminants.
