Claims
- 1. A colorless toner composition overcoated on an ink jet ink print, said colorless toner composition comprising a toner resin and at least two additives selected from the group consisting of a thermal stabilizer, an ultraviolet absorber and a free radical inhibitor, wherein the ratio of said toner resin to said additives is from about 1:1 to 99:1 by weight, said toner composition being adhered to the ink jet ink print, and wherein at least one of said additives has interacted with a colorant molecule or polymer of the ink jet ink.
- 2. A colorless toner composition 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.
- 3. A colorless toner composition as in claim 2 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.
- 4. A colorless toner composition as in claim 1 wherein at least one of the at least two additives is an ultraviolet absorber containing a functional group having the structure:
- 5. A colorless toner composition as in claim 1 wherein at least one of the at least two additives is a free radical inhibitor containing a functional group having the structure:
- 6. A colorless toner composition as in claim 1 wherein at least one of the at least two additives is a thermal stabilizer having the structure:
- 7. A colorless toner composition as in claim 1 wherein at least one of the at least two additives is a thermal stabilizer selected from the group consisting of phenols, phosphates, and combinations thereof.
- 8. A colorless toner composition as in claim 4 wherein the ultraviolet absorber is defined by a structure selected from the group consisting of wherein n is an integer from about 1 to 5.
- 9. A colorless toner composition as in claim 5 wherein the free radical inhibitor is defined by the structure:
- 10. A colorless toner composition as in claim 1 further comprising an effective amount of a charge control agent.
- 11. A colorless toner composition as in claim 10 wherein the charge control agent is selected from the group consisting of alkylsalicylic acids, hydroxynaphthoic acids, quaternary ammonium salts, oxides of metal alkyls, salicylic acid metal complexes, calixarene compounds, and organic boron compounds.
- 12. A colorless toner composition as in claim 1 further comprising a low-melt wax.
- 13. A colorless toner composition as in claim 12 wherein the low-melt wax is selected from the group consisting of carnauba waxes, microcrystalline waxes, paraffin waxes, rice waxes, low molecular weight polypropylenes, low molecular weight polyethylenes, and oxidized polypropylenes modified by acidic monomers.
