Claims
- 1. A method of creating and protecting an image on a substrate, comprising:ink-jetting an image on a substrate; and overcoating the image with a toner composition comprising: a colorless toner resin, and at least two additives independently selected from the group consisting of ultraviolet absorbers, free radical inhibitors, and thermal stabilizers, wherein the ratio of said toner resin to said additives is from about 1:1 to 99:1 by weight.
- 2. A method as in claim 1 wherein one of the at least two additives is a free radical inhibitor.
- 3. A method as in claim 1 wherein one of the at least two additives is an ultraviolet absorber.
- 4. A method as in claim 1 wherein one of the at least two additives is a thermal stabilizer.
- 5. A method as in claim 1 wherein at least three additives are present including ultraviolet absorbers, free radical inhibitors, and thermal stabilizers.
- 6. A method as in claim 1 wherein said toner resin is selected from the group consisting of styrene resins, styrene copolymer resins, polyethylenes, polyethers, polyols, acrylic resins, vinyl resins, ethylenic resins, polyamide resins, polyester resins, phenolic resins, silicone resins, xylene resins, epoxy resins, terpene resins, rosins, modified rosins, and combinations thereof.
- 7. A method as in claim 6 wherein the toner resin is a styrene selected from the group consisting of polystyrenes, polychlorostyrenes, polyvinyltoluenes, styrene-vinyltoluene copolymers, styrene-vinylnaphthalene copolymers, styrene-acrylic acid copolymers, styrene-methacrylic acid copolymers, styrene-acrylonitrile copolymers, styrene-butadiene copolymers, and styrene-maleic acid ester copolymers.
- 8. A method as in claim 5 wherein the ultraviolet absorbers contain a functional group having the structure:
- 9. A method as in claim 5 wherein the free radical inhibitors contain a functional group having the structure:
- 10. A method as in claim 5 wherein the thermal stabilizers have the structure:
- 11. A method as in claim 5 wherein the thermal stabilizers are selected from the group consisting of phenols, phosphates, and combinations thereof.
- 12. A method as in claim 8 wherein the ultraviolet absorbers are defined by a structure selected from the group consisting of wherein n is an integer from about 1 to 5.
- 13. A method as in claim 9 wherein the free radical inhibitors are defined by the structure:
- 14. A method as in claim 1 further comprising an effective amount of a charge control agent.
- 15. A method as in claim 1 further comprising a low-melt wax.
