Claim:
A phase change ink comprising a colorant, an initiator, and a phase change ink carrier, said carrier comprising at least one radically curable monomer compound and a compound of the formula wherein R 1 and R 1 ′ each, independently of the other, is (i) an alkyl group having at least one ethylenic unsaturation therein, including linear and branched, cyclic and acyclic, and substituted and unsubstituted alkyl groups, and wherein hetero atoms either may or may not be present in the alkyl group, (ii) an arylalkyl group having at least one ethylenic unsaturation therein, including substituted and unsubstituted arylalkyl groups, wherein the alkyl portion of the arylalkyl group can be linear or branched, cyclic or acyclic, and substituted or unsubstituted, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the arylalkyl group, or (iii) an alkylaryl group having at least one ethylenic unsaturation therein, including substituted and unsubstituted alkylaryl groups, wherein the alkyl portion of the alkylaryl group can be linear or branched, cyclic or acyclic, and substituted or unsubstituted, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the alkylaryl group, R 2 , R 2 ′, and R 3 each, independently of the others, are (i) alkylene groups, including linear and branched, saturated and unsaturated, cyclic and acyclic, and substituted and unsubstituted alkylene groups, and wherein hetero atoms either may or may not be present in the alkylene group, (ii) arylene groups, including substituted and unsubstituted arylene groups, and wherein hetero atoms either may or may not be present in the arylene group, (iii) arylalkylene groups, including substituted and unsubstituted arylalkylene groups, wherein the alkyl portion of the arylalkylene group can be linear or branched, saturated or unsaturated, cyclic or acyclic, and substituted or unsubstituted, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the arylalkylene group, or (iv) alkylarylene groups, including substituted and unsubstituted alkylarylene groups, wherein the alkyl portion of the alkylarylene group can be linear or branched, saturated or unsaturated, cyclic or acyclic, and substituted or unsubstituted, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the alkylarylene group, and n is an integer representing the number of repeat amide units and is at least 1.
