A phase change ink composition useful for inkjet printers for color printing comprises a phase change ink carrier, and a brominated alcohol-substituted colorant compound (1) that has desirable magenta color and good light fastness, and exhibits desirable solubility characteristics. A phase change ink composition comprises a phase change ink carrier and a colorant compound of formula (1). [Image] Y : a hydrogen atom or a bromine atom; n : 0, 1, 2, 3 or 4; R 1an alkylene or an arylalkylene; X : a hydrogen atom; a group having a formula -C(O)-R 2; an alkyleneoxy, aryleneoxy, arylalkyleneoxy or alkylaryleneoxy; or a group having a formula -C(O)-NH-R 4; where R 2 and R 4an alkyl, an aryl, an arylalkyl or an alkylaryl; An independent claim is also included for a process comprising incorporating into an ink jet printing apparatus a phase change ink composition as above; melting the ink; and causing droplets of the melted ink to be ejected in an imagewise pattern onto a substrate. |
