Abstract:
An ink jet ink composition comprising water, a colorant of dye or pigment, or a mixture of dye and pigment, and a water-soluble or ink-compatible anti-intercolor bleed agent represented by formula (I): ##STR6##whereina) R.sub.d is selected from the group consisting of C.sub.1 to C.sub.30 alkyl, cyclic alkyl (C.sub.3 to C.sub.30), phenyl, napthyl, and aromatic groups either with or without the presence of a nitrogen or oxygen atom, and the required substituents of each carbon atom of said R.sub.d group are independently selected from the group consisting of hydrogen (H) and fluorine (F) atoms;b) R.sub.g is selected from the group consisting of C.sub.1 to C.sub.30 alkyl, cyclic alkyl (C.sub.3 to C.sub.30), and aromatic (.gtoreq.C.sub.5) groups either with or without the presence of a nitrogen or oxygen atom, and the substituents of each carbon atom of said R.sub.g group are independently selected from the group consisting of hydrogen (H) and fluorine (F) atoms;c) T is selected from the group consisting of C.sub.1 to C.sub.30 alkyl and cyclic alkyl (C.sub.3 to C.sub.30) groups either with or without the presence of a nitrogen or oxygen atom, and the substituents of each carbon atom of said T group are independently selected from the group consisting of hydrogen (H) and fluorine (F) atoms; andd) (X.sup.+) is a cation selected from the group consisting of a hydrogen cation; a monovalent metal cation; a multivalent metal cation; and an ammonium group of the general formula ##STR7##wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are independently selected from the group consisting of hydrogen, alkyl group, hydroxyalkyl groups, hydroxyl terminated polyalkyleneoxides, and a group comprising one or more alkyleneoxide moieties terminated with hydrogen, amine, hydroxyl, or alkyl group;wherein the water-soluble or ink-compatible bleed agent is present in a concentration between about 0.3% to about 0.8% by weight of the ink jet ink composition.
