Abstract
Disclosed is an ink composition comprising a liquid ink vehicle, a colorant, and a cyclic siloxane monomer composition capable of undergoing a ring-opening polymerization process upon contact with an anionic base. Another embodiment of the present invention is directed to a process which comprises (a) providing (1) a first ink comprising water and at least one cyclic siloxane monomer composition; and (2) a second ink comprising a liquid ink vehicle and an anionic base capable of causing the cyclic siloxane monomer to polymerize upon contact therewith, wherein at least one of the first ink and the second ink further comprises a colorant; (b) incorporating into an ink jet printing apparatus at least one of the first ink and the second ink; (c) applying the first ink onto a substrate; and (d) applying the second ink onto the substrate; wherein at least one of the first ink and the second ink is ejected from the ink jet printing apparatus in an imagewise pattern onto the substrate; and wherein the process results in at least some portions of the substrate bearing images formed from both the first ink and the second ink, said portions forming a printed image containing a polysiloxane and the colorant.
