Phase change ink formulations, colorant formulations, and methods of forming colorants

摘要

A compound having the formula 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 of at least 12. A solid phase change ink composition is also disclosed containing a colorant comprising a chromophore that absorbs light from the visible wavelength range and has the formula wherein R₁, Z, and the carbonyl can be comprised by a common ring, and wherein n is an integer of at least 12. Also disclosed is a method of forming a colorant wherein a first compound having the formula is reacted with a second compound having the formula Z(CH₂)_nCH₃ wherein n is an integer of at least 12 to form a third compound having the formula wherein the third compound comprises a chromophore that absorbs light from the visible wavelength range.
