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.
摘要:
A process for the transfer color printing of synthetic textile materials wherein the dyestuff used is a 1-hydroxy-2-(optionally substituted) lower alkyl-4-anilinoanthraquinone optionally having from 1 to 3 substituents in the anilino nucleus. Preferably the latter carries a single substituent ortho to the --NH--group.
