Abstract

Claims (17)

1. A heat transferable protective overcoat comprising a hydroxyphenyl triazine compound in a polymeric binder, wherein the hydroxyphenyl triazine compound comprises a mixture of structures of the following Formulas:

wherein for Formula I each R 3 is a substituent, and m, n, and p are each 0 to 3;

wherein for Formula I″ each R 2 is an alkyl group of up to 8 carbon atoms, each R 1 is a substituent, each R 3 is a substituent, and m, n, and p are each 0 to 2; and

wherein for Formula II each R 1 is a substituent, each R 3 is a substituent, and m, n, and p are each 0 to 2.

2. The overcoat of claim 1 wherein the hydroxyphenyl triazine compound is present in an amount of 2-30 wt % of the overcoat.

3. A thermal dye sublimation donor element comprising the overcoat of claim 1 .

4. The overcoat of claim 1 wherein each R 1 and each R 3 group present is an alkyl, alkoxy, or hydroxy group.

5. A protected image comprising an image and the transferred overcoat of claim 6 on the image.

6. The overcoat of claim 1 wherein at least one R 1 or R 3 is an ester group.

7. A protected image comprising an image and the transferred overcoat of claim 6 on the image.

8. A protected image reproduction comprising an image and the transferred overcoat of claim 1 on the image.

9. The protected image of claim 8 comprising a dye selected from the group consisting of methine, azamethine, merocyanine, and azo dyes.

10. The protected image of claim 9 comprising a methine dye.

11. A thermal dye sublimation image comprising an image on a substrate and the overcoat of claim 1 on the image.

12. A process for protecting an image from UV radiation without degrading the protection from daylight exposure comprising applying a thermally transferable overcoat of claim 1 to the image.

13. The overcoat of claim 1 additionally containing solid particles.

14. The overcoat of claim 13 wherein the solid particles are polymeric beads.
