Claims
- 1. An ink jet printing method, comprising the steps of:A) providing an ink jet printer that is responsive to digital data signals; B) loading said printer with an ink-receiving element comprising a support having thereon an ink-receiving layer; C) loading said printer with an ink jet ink set for color printing comprising: (a) a yellow ink comprising a carrier and a yellow azoaniline dye; (b) a magenta ink comprising a carrier and a magenta anthrapyridone dye; and (c) a cyan ink comprising a carrier and Direct Blue 307; and D) printing on said ink-receiving layer using said inkjet ink in response to said digital data signals; wherein said magenta anthrapyridone dye is a sulfonic acid or sulfonate derivative of a compound represented by the general formula. wherein: R1 represents hydrogen, or a substituted or unsubstituted alkoxycarbonyl, carboxyl, benzoyl, alkyl, aryl, hetaryl, alkoxy or phenoxy group; R2 represents hydrogen or a substituted or unsubstituted alkyl, alicyclic, aryl or hetaryl group; R3 represents hydrogen, carboxyl, or a substituted or unsubstituted alkyl, alicyclic, aryl, hetaryl, alkoxy or phenoxy group; each X independently represents hydrogen, halogen, nitro, hydroxyl, carboxyl, or a substituted or unsubstituted alkyl, alicyclic, aryl, hetaryl, alkoxy, phenoxy, amino, amido or sulfonamido group; and n represents 0, 1, 2 or 3; said compound not containing a quaternary ammonium or phosphonium counter ion.
- 2. The method of claim 1 wherein said yellow azoaniline dye is Direct Yellow 132, Direct Yellow 107, Direct Yellow 86 or mixtures thereof.
- 3. The method of claim 1 wherein R1 is benzoyl.
- 4. The method of claim 1 wherein R2 is hydrogen.
- 5. The method of claim 1 wherein R3 is a sulfonated phenoxy group.
- 6. The method of claim 1 wherein n is 1 and X is a sulfonate group.
- 7. The method of claim 1 wherein each ink contains from about 5 to about 60 weight percent of a humectant.
- 8. The method of claim 1 wherein each ink contains a surfactant.
- 9. The method of claim 1 further comprising an additional ink of a carrier and a black colorant.
- 10. The method of claim 9 wherein said black colorant is Reactive Black 31, Direct Black 19, Direct Black 168, Solubilized Sulfur Black 1 or a black pigment.
- 11. The method of claim 1 wherein each said carrier is water.
- 12. The method of claim 1 wherein each ink contains 0.1 to 10.0 weight percent of dye.
- 13. The method of claim 1 further comprising a light cyan ink (d) comprising a carrier and said cyan dye in (c) but at a concentration of about 5% to about 50% of the amount of said cyan dye in (c).
- 14. The method of claim 1 further comprising a light magenta ink (e) comprising a carrier and said magenta dye in (b) but at a concentration of about 5% to about 50% of the amount of said magenta dye in (b).
