- 6. The element of claim 5 wherein the magenta dye is one where each of R1 through R5 is an alkyl group and X is an alkoxy group.
- 7. The element of claim 1 wherein the yellow dye is a dye of formula III:
- 8. The element of claim 6 wherein the yellow dye is one where each R11 and R12 is an alkyl group and R14 is a cyano, carbamoyl, or alkoxycarbonyl group.
- 9. The element of claim 1 further containing a second yellow dye.
- 10. The element of claim 9 wherein the second yellow dye is a dye of Formula II:
- 11. The element of claim 9 further including an additional dye of formula IV:
- 12. The element of claim 11 further comprising an IR dye.
- 13. The element of claim 12 wherein the IR dye is a dye of formula V:
- 14. A thermal dye transfer imaging donor element comprising a magenta dye donor containing a combination of dyes including a magenta dye and two yellow dyes.
- 15. The element of claim 14 in which the magenta and two yellow dyes are represent by formulas I, II, and III, respectively:
- 16. The element of claim 15 further comprising an additional dye of formula IV:
- 17. A method of forming an image comprising imagewise transferring a dye from the element of claim 1 to a receiving element.
- 18. A method of forming an image comprising imagewise transferring a dye from the element of claim 14 to a receiving element.
- 19. A combination of dyes useful for forming a magenta image comprising a magenta dye and a yellow dye exhibiting an RMS error of less than 0.015.
- 20. The combination of claim 19 wherein the RMS error is less than 0.010.
- 21. The combination of claim 20 wherein the RMS error is less than 0.008.
- 22. The combination of claim 19 wherein the magenta dye is a phenylazopyrazole dye.
- 23. The combination of claim 19 wherein the magenta dye is represented by formula I:
- 24. The combination of claim 23 wherein the magenta dye is one where each of R1 through R5 is an alkyl group and X is an alkoxy group.
- 25. The combination of claim 19 wherein the yellow dye is a dye of formula III
- 26. The combination of claim 25 wherein the yellow dye is one where each R11 and R12 is an alkyl group and R14 is a cyano, carbamoyl, or alkoxycarbonyl group.
- 27. The combination of claim 19 further containing a second yellow dye.
- 28. The combination of claim 27 wherein the second yellow dye is a dye of Formula II
- 29. The combination of claim 27 further comprising an additional dye of formula IV:
- 30. The combination of claim 28 further comprising an additional dye of formula IV:
