The present invention relates to aqueous ink jet ink compositions comprising a water-soluble or ink-compatible anti-intercolor bleed agent. The ink jet ink compositions typically comprise 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. In one embodiment the water-soluble or ink-compatible intercolor bleed agents of the invention comprise glycine materials with or without a fluorine atom and are represented by formula (I) in either ionic or nonionic forms, particularly those of fluorinated glycine salts with high fluorine content. The water-soluble or ink-compatible anti-intercolor bleed agent in an ink jet composition is believed to accelerate ink drying and to form hydrophobic layers on a print substrate near the image boundary in an ink jet printing process, thus minimizing undesired mixing of different neighboring inks resulting in a reduction of intercolor bleed. The ink jet ink compositions of the present invention exhibit reduced drying time, intercolor bleeding, and image defect as well as providing uniform ink image on transparencies. The ink jet ink compositions comprising the water-soluble or ink-compatible anti-intercolor bleed agents can be used in a multi-color ink jet printing process to obtain multi-color ink jet images at a high speed.
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):
An ink jet printing process comprises printing a “first ink” of 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):
An ink jet printing process comprising printing a “first ink” which is a black dye ink or a carbon black ink either with or without chemically modified carbon black particles and a “second ink” which is a color dye-based or pigment-based ink that has 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):
A multi-color ink jet printing process comprising printing a set of four or more multi-color ink jet inks by their corresponding printheads in any desired printing method and sequence of said multi-color ink jet inks according to digital data signals onto a print substrate, wherein said set of four or more multi-color ink jet inks has at least one ink jet ink having 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):
An ink jet ink composition comprising water, a colorant of a dye or pigment, or a mixture of dye and pigment, and a water-soluble or ink-compatible anti-intercolor bleed agent which is a metal or ammonium salt of a glycine material selected from the group consisting of Glycine, N-methyl-N-[(heptadecafluorooctyl)sulfonyl]-, salts;
An ink jet ink composition comprising water, a colorant of a dye or pigment, or a mixture of dye and pigment, and a water-soluble or ink-compatible anti-intercolor bleed agent which is a glycine material selected from the group consisting of polyethyleneglycol ester of N-methyl-N-[(heptadecafluorooctyl)sulfonyl]Glycine;
An ink jet ink composition comprising water, a colorant of a dye or a pigment, or a mixture of dye and pigment, and a water-soluble or ink-compatible anti-intercolor bleed agent which is a metal or an ammonium salt of glycine material selected from the group consisting of N-(fluoroalkyl sulfonyl), N-(alkyl), glycine salts, N-(fluorocycloalkyl sulfonyl), N-(alkyl), glycine salts, N-(alkylsulfonyl), N-(fluoroalkyl), glycine salts, N-(cycloalkylsulfonyl), N-(fluoroalkyl), glycine salts, N-(fluoroalkyl sulfonyl), N-(fluoroalkyl), glycine salts, N-(fluorocycloalkyl sulfonyl), N-(fluoroalkyl), glycine salts, and N-(fluoroalkyl sulfonyl), N-(fluorocycloalkyl), glycine salts;
