Beschreibung
Zusammenfassung:	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.
