Patent ID: 7097669

Claim:
A colorant composition comprising: wherein said F 1 =(B) x (C) y H, and further wherein H is hydrogen; and B is an alkylene oxide residue, said alkylene oxide residue being selected from at least one of the following: styrene oxide, glycidyl methyl ether, isobutyl glycidyl ether, isopropylglycidyl ether, t-butyl glycidyl ether, 2-ethylhexylglycidol ether, and glycidyl hexadecyl ether; and x is an integer from 1–20 representing the number of repeat alkylene oxide units; and C is an alkylene oxide residue selected from at least one of the following: ethylene oxide, propylene oxide, butylene oxide, styrene oxide, glycidyl methyl ether, isobutyl glycidyl ether, isopropyl glycidyl ether, t-butyl glycidyl ether, 2-ethylhexylglycidol ether, and glycidyl hexadecyl ether, and y is an integer less than about 20; and F 2 , F 3 , F 4 , F 5 , F 6 , F 7 , F 9 , and F 10 each are independently selected from: hydrogen, alkyl, alkoxy, SO 3 − , SO 3 Na, SO 3 K, sulfonamide, acetamide, nitro, and cyano; and F 8 is selected from the group of: hydrogen, alkyl, alkoxy, SO 3 − , SO 3 Na, SO 3 K, sulfonamide, acetamide, nitro, and cyano, and nitrogen-bound alkylene oxide moiety; said F 6 and said F 7 may optionally be linked together to form a heterocyclic or aromatic ring; said F 7 and said F 8 may optionally be linked together to form a heterocyclic or aromatic ring; and A− comprises an anion when said colorant composition does not contain SO 3 − .
