    Abstract: Present embodiments generally relate to a novel clear or colorless overcoat composition that may be used for overcoating, for example, ink based images and xerographic images. The overcoat composition, which may be used as a base for a clear solid ink, comprises one or more waxes. Also included in the present embodiments is methods for using and stabilizing the overcoat composition as a solid ink.

    Abstract: Disclosed is a phase change ink comprising (a) a colorant and (b) a phase change ink carrier, said carrier comprising (i) a branched triamide and (ii) a polyethylene wax having an average peak molecular weight of from about 350 to about 730 and a polydispersity of from about 1.0001 to about 1.500. Also disclosed is a process which comprises (1) incorporating into an ink jet printing apparatus a phase change ink comprising (a) a colorant and (b) a phase change ink carrier, said carrier comprising (i) a branched triamide and (ii) a polyethylene wax having an average peak molecular weight of from about 350 to about 730 and a polydispersity of from about 1.0001 to about 1.500; (2) melting the ink; and (3) causing droplets of the melted ink to be ejected in an imagewise pattern onto a substrate.

    Abstract: A phase change ink composition for printing on ophthalmic lenses including a straight chain hydrocarbon wax and a branched hydrocarbon wax; an amide, wherein the amide is present in an amount of greater than about 25 percent by weight based on the total weight of the ink composition; a rosin ester; and a colorant. A phase change ink composition for printing on ophthalmic lenses including a straight chain hydrocarbon wax and a branched hydrocarbon wax; an amide, wherein the amide comprises a combination of at least two members of the group consisting of monoamide, triamide, and tetra-amide; a rosin ester; and a colorant. An ink jet printer stick or pellet comprising the phase change ink composition.
