Abstract:
The invention encompasses a compound having the formula: 1 wherein R1, Z and the carbonyl can be comprised by a common ring, wherein R1 comprises a chromophore that absorbs light from the visible wavelength range, and wherein n is an integer that is at least 12. The invention also encompasses a solid phase change ink composition. Such composition includes a phase change ink carrier and a colorant. The colorant comprises a chromophore that absorbs light from the visible wavelength range, and has the formula: 2 wherein R1, Z and the carbonyl can be comprised by a common ring, wherein n is an integer that is at least 12. Additionally, the invention encompasses a method of forming a colorant. A first compound having the formula, 3 is reacted with a second compound having the formula Z(CH2)nCH3, wherein n is an integer that is at least 12, to form a third compound having the formula, 4 wherein the third compound comprises a chromophore that absorbs light from the visible wavelength range.
Abstract:
Disclosed is a phase change ink composition comprising a phase change ink carrier and a colorant compound of the formula 1 wherein M is an atom or group of atoms capable of bonding to the central cavity of a phthalocyanine molecule, wherein axial ligands optionally can be attached to M. Also disclosed are printing processes using the phase change inks.
