Abstract: This invention relates to an ink jet ink set comprising; A) a cyan ink comprising an aqueous vehicle and a sulfonated copper phthalocyanine dye, B) a magenta ink comprising an aqueous vehicle and an azo-naphthol derivative magenta dye, a metal complex magenta dye, or a anthrapyridone magenta dye or mixtures thereof, C) a yellow ink comprising an aqueous vehicle and a pyrazoleazoindole yellow dye or azo pyrazole-azole yellow dye or mixtures thereof and D) a black ink comprising an aqueous vehicle and a metal complex black dye.

Abstract: An ink jet ink comprising: a) at least one first metal complex black dye that when printed alone on a receiving element gives a CIELAB a* value>0 and at 1.0 Status A visual density; b) at least one second metal complex black dye that when printed alone on a receiving element gives a CIELAB a* value<0 and at 1.0 Status A visual density; and c) at least one yellow azo-aniline yellow dye or metal complex yellow dye or mixtures thereof.

Abstract: An ink jet ink set comprising: a) a cyan ink comprising a carrier and a sulfonated copper phthalocyanine dye; b) a magenta ink comprising a carrier and an anthrapyridone magenta dye or metal complex magenta dye, or azo-naphthol derivative magenta dye or mixture thereof; c) a yellow ink comprising a carrier and an azo-aniline yellow dye or metal complex yellow dye or mixtures thereof; and d) a trisazo black dye of the following structure where Met is a metal atom, preferably Al, Co, Cr, Cu, Fe, or Ni; R1 is a phenyl or naphthalene radical substituted by 1, 2 or 3 substituents selected from the group consisting of OH, O(C1-C6)-alkyl, COOM, SO3M and NH2; R2 is C1-C6-alkyl, n is 0 or 1, X is a chemical bond or —CO— or —SO2—; R3 is H, methyl or O(C1-C6)-alkyl; R4 and R5 are each H, COOM or SO3M; R6 is a phenyl, pyridyl or pyrazole radical substituted by 1, 2 or 3 substituents selected from the group consisting of OH, O(C1-C6)-alkyl, COOM, SO3M, NH2, NHaryl, NHacyl and phenlysulfo; and M is ammonium, H, K, Li,

Abstract: An ink jet printing method, having the steps of: A) providing an ink jet printer that is responsive to digital data signals; B) loading the printer with an ink-receiving element having a support having thereon an ink-receiving layer, C) loading the printer with an ink jet ink set for color printing having: (a) a yellow ink having a carrier and a yellow dye; (b) a magenta ink having a carrier and a mixture of a water-soluble, magenta anthrapyridone dye and Reactive Red 23, Reactive Red 24, Reactive Red 31, Reactive Red 120, Reactive Red 180, Reactive Red 241, Acid Red 35, Acid Red 52, Acid Red 249, Acid Red 289, Acid Red 388, Direct Red 227 or CAS No. 153204-88-7; and (c) a cyan ink having a carrier and a cyan dye. and D) printing on the ink-receiving layer using the ink jet ink in response to the digital data signals.
