Abstract
Disclosed is a phase change ink composition comprising a phase change ink carrier and a colorant compound of the formula wherein Y is a hydrogen atom or a bromine atom, n is an integer of 0, 1, 2, 3, or 4, R1 is an alkylene group or an arylalkylene group, and X is (a) a hydrogen atom, (b) a group of the formula wherein R2 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, (c) an alkyleneoxy, aryleneoxy, arylalkyleneoxy, or alkylaryleneoxy group, or (d) a group of the formula wherein R4 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group.

A phase change ink composition comprising a phase change ink carrier and a colorant compound of the formula
- wherein Y is a hydrogen atom or a bromine atom, n is an integer of 0, 1, 2, 3, or 4, R1 is an olkylene group or an arylalkylene group, and X is (a) a hydrogen atom. (b) a group of the formula
- wherein R2 is on alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, (c) an alkyleneoxy, aryleneoxy, arylalkyleneoxy, or alkylaryleneoxy group, or (d) a group of the formula
- wherein R4 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group.
A process which comprises (1) incorporating into an ink jet printing apparatus a phase change ink composition comprising a phase change ink carrier and a colorant compound of the formula
- wherein Y is a hydrogen atom or a bromine atom, n is an integer of 0, 1, 2, 3, or 4, R1 is an alkylene group or an arylalkylene group, and X is (a) a hydrogen atom, (b) a group of the formula
- wherein R2 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, (c) an alkyleneoxy, aryleneoxy, arylalkyleneoxy, or alkylaryleneoxy group, or (d) a group of the formula
- wherein R4 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group;
- (2) melting the ink;
- and (3) causing droplets of the melted ink to be ejected in an imagewise pattern onto a substrate.
