Abstract:
1. A method of forming a colorant comprising reacting a first compound of the formula wherein R 1 is a group of the formula wherein R 80 , R 81 , R 82 , R 83 , R 84 , R 85 , R 86 , R 87 , R 88 , and R 89 are selected from the group consisting of hydrogen, halogens, hydroxy groups, alkoxy groups, trifluoromethyl groups, and alkyl groups, and can be the same as one another or different from one another; wherein R 3 , R 4 , R 5 , and R 6 are selected from the group consisting of hydrogen and carbon-containing materials and can be the same as one another or different from one another; and X represents a leaving group, with a second compound of the formula Z(CH 2 ) n CH 3 , wherein Z is NH or wherein y is an integer of from 0 to 300, and wherein n is an integer that is at least 12, to form a third compound of the formula wherein the third compound comprises a chromophore that absorbs light from the visible wavelength range, and wherein R 1 , Z, and the carbonyl can form a common ring.
