1. A phase change ink composition including one or more ester resins, the ink composition comprising:
an optional colorant; at least one crystalline phase-change agent; an amorphous binder agent; and optionally one or more additives; wherein
the at least one amorphous binder agent comprises at least one ester compound represented by:or a mixture of one or more compounds of General Formulas I and/or II;
where R1 is: (a) an alkylene group, including substituted and unsubstituted alkylene groups, wherein hetero atoms either may or may not be present in the alkylene group; (b) an arylene group, including substituted and unsubstituted arylene groups, wherein hetero atoms either may or may not be present in the arylene group: (c) an arylalkylene group, including substituted and unsubstituted arylalkylene groups, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of the arylalkylene group; or (d) an alkylarylene group, including substituted and unsubstituted alkylarylene groups, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of the alkylarylene group;
two or more substituents can be joined together to form a ring; andeach of R2-R25 are independently selected from the group consisting of hydrogen, alkyl groups, arylalkyl groups, alkylaryl groups, and heterocyclic groups; and wherein x is an integer of one or more.
