Abstract

A phase change ink carrier composition comprising at least one anhydride/alcohol inclusive reaction product.

Claims

1. A phase change ink comprising at least one anhydride/alcohol inclusive reaction product made from alkylsuccinic anhydride or alkenylsuccinic anhydride.

2. A phase change ink comprising at least one anhydride/alcohol inclusive reaction product made from benzophenone tetracarboxylic dianhydride.

3. A phase change ink comprising at least one anhydride/alcohol inclusive reaction product that is an anhydride/alcohol-based ester adduct made from at least one monohydric alcohol.

4. The phase change ink of claim 3 wherein the anhydride/alcohol inclusive reaction product is formed from a dianhydride reacted with the monohydric alcohol and also reacted with a polyol.

5. A phase change ink comprising at least one anhydride/alcohol inclusive reaction product that is an anhydride/alcohol-based ester adduct made from an alcohol selected from the group consisting of hydroabietyl alcohol, octylphenol ethoxylate and octadecyl alcohol.

6. A phase change ink comprising at least one anhydride/alcohol inclusive reaction product made from a cyclic anhydride selected from the group consisting of poly(methyl vinyl ester-maleic acid);

poly(acrylic acid-co-maleic acid);

poly(vinyl chloride-co-vinyl-acetate-co-maleic acid);

poly(ethylene-maleic anhydride);

poly(maleic anhydride-1-octadecene);

poly(styrene-co-maleic anhydride);

poly(methyl vinyl ether-maleic anhydride);

poly(ethylene-co-ethyl acrylate-co-maleic anhydride);

poly(ethylene-co-vinyl acetate)-graft-maleic anhydride;

polyethylene-graft-maleic anhydride; and

polypropylene-graft-maleic anhydride.

7. A phase change ink comprising at least one anhydride/alcohol inclusive reaction product that is the covalently bound product of at least one nucleophile-containing colorant material and at least one anhydride.

8. A method of making a phase change ink, comprising:

forming a carrier composition;

the forming the carrier composition including reacting one or more alcohols with alkenylsuccinic anhydride; and

combining the carrier composition with at least one colorant.

9. A method of making a phase change ink, comprising:

forming a carrier composition;

the forming the carrier composition including reacting one or more alcohols with alkylsuccinic anhydride; and

combining the carrier composition with at least one colorant.

10. A method of making a phase change ink, comprising:

forming a carrier composition;

the forming the carrier composition including reacting benzophenone tetracarboxylic dianhydride with one or more alcohols; and

combining the carrier composition with at least one colorant.

11. A method of making a phase change ink, comprising:

forming a carrier composition;

the forming the carrier composition including reacting an anhydride with one or more monohydric alcohols; and

combining the carrier composition with at least one colorant.

12. The method of claim 11 wherein the anhydride is a dianhydride, and wherein the forming the carrier composition comprises reacting at least some of the dianhydride with one of said one or more monohydric alcohols, and also reacting the at least some of the dianhydride with a polyol.

13. A method of making a phase change ink, comprising:

forming a carrier composition;

the forming the carrier composition including reacting an anhydride with an alcohol selected from the group consisting of hydroabietyl alcohol, octylphenol ethoxylate and octadecyl alcohol; and

combining the carrier composition with at least one colorant.

14. A method of making a phase change ink, comprising:

forming a carrier composition;

the forming the carrier composition including reacting one or more alcohols with a cyclic anhydride selected from the group consisting of poly(methyl vinyl ether-maleic acid);

poly(acrylic acid-co-maleic acid);

poly(vinyl chloride-co-vinyl-acetate-co-maleic acid);

poly(ethylene-maleic anhydride);

poly(maleic anhydride-1-octadecene);

poly(styrene-co-maleic anhydride);

poly(methyl vinyl ether-maleic anhydride);

poly(ethylene-co-ethyl acrylate-co-maleic anhydride);

poly(ethylene-co-vinyl acetate)-graft-maleic anhydride;

polyethylene-graft-maleic anhydride; and

polypropylene-graft-maleic anhydride; and

combining the carrier composition with at least one colorant.

15. A method of forming a phase change ink, comprising:

reacting at least one nucleophile-containing colorant material with at least one anhydride to form a colored material; and

incorporating the colored material into a solid ink block.
