1. A phase change ink comprising:
(I) a phase change ink carrier; and (II) a colorant compound of the formulawherein:
(a) Ra and Rb each, independently of the other, are:
(i) hydrogen;(ii) alkyl, including substituted and unsubstituted alkyl, wherein hetero atoms may optionally be present in alkyl;(iii) aryl, including substituted and unsubstituted aryl, wherein hetero atoms may optionally be present in aryl;(iv) arylalkyl, including substituted and unsubstituted arylalkyl, wherein hetero atoms may optionally be present in either the aryl or the alkyl portion of arylalkyl; or(v) alkylaryl, including substituted and unsubstituted alkylaryl, wherein hetero atoms may optionally be present in either the aryl or the alkyl portion of alkylaryl; and (b) R1 and R2 each, independently of the other, are:
(i) hydrogen, provided that at least one of R1 and R2 is other than hydrogen;(ii) alkyl, including substituted and unsubstituted alkyl, wherein hetero atoms may optionally be present in alkyl, provided that when R1 and R2 are both alkyl at least one of R1 and R2 has at least about 6 carbons;(iii) aryl, including substituted and unsubstituted aryl, wherein hetero atoms may optionally be present in aryl;(iv) arylalkyl, including substituted and unsubstituted arylalkyl, wherein hetero atoms may optionally be present in either the aryl or the alkyl portion of arylalkyl; or(v) alkylaryl, including substituted and unsubstituted alkylaryl, wherein hetero atoms may optionally be present in either the aryl or the alkyl portion of alkylaryl. |
