Permanent heat activated electrographic printing process and composition

Abstract

An image is printed on a medium by means of an electrographic device using an ink composition comprising heat activated inks, without substantial activation of the inks during the process of printing the image onto the medium. A molecular sieve added to the ink composition assists activation control. The image is transferred from the medium to the object on which the image is to permanently appear by applying sufficient heat and pressure to the medium to activate and permanently transfer the inks from the medium to an object.
