Abstract

The reaction product of at least one polyanhydride and at least one amine is disclosed. A phase change ink composition and a phase change ink containing the polyanhydride/amine adduct are also disclosed.

Claims

1. A material resulting from the reaction between at least one polyanhydride and at least one mono-amine;

wherein said polyanhydride is selected from the group consisting of 3,3′

,4,4′

-benzophenonetetracarboxylic dianhydride, 1,2,4,5-benzenetetracarboxylic dianhydride, 1,4,5,8-naphthalenetetracarboxylic dianhydride, 3,4,9,10-perylenetetracarboxylic dianhydride, bicyclo(2,2,2)octo-7-ene-2,3,5,6-tetracarboxylic dianhydride, ethylenediaminetetraacetic dianhydride, and diethylenetriaminepentaacetic dianhydride;

wherein the resulting material is a non-oligomeric and non-polymeric imide.

2. The material according to claim 1 wherein the reaction between the at least one polyanhydride and the at least one mono-amine further includes at least one other nucleophile.

3. The material according to claim 2 wherein the at least one other nucleophile is selected from the group consisting of alcohols, colorants containing alcohol functionalities, colorants containing amine functionalities, and mixtures thereof.

4. The material according to claim 1 wherein the material is a polyanhydride/mono-amine adduct.

5. The material according to claim 1 wherein the dianhydride is an aromatic dianhydride.

6. The material according to claim 5 wherein the aromatic dianhydride is benzophenone tetracarboxylic dianhydride.

7. The material according to claim 4 wherein the polyanhydride/mono-amine adduct is selected from polyanhydride-based amide adducts and polyanhydride-based imide adducts and mixtures thereof.

8. The material according to claim 1 wherein the at least one mono-amine is selected from the group consisting of hydroabietyl amine, octadecyl amine and mixtures hereof.

9. A phase change ink carrier composition comprising at least one polyanhydride/mono-amine-based adduct, wherein a polyanhydride component of said adduct is selected from the group consisting of 3,3′

,4,4′

-benzophenonetetracarboxylic dianhydride, 1,2,4,5-benzenetetracarboxylic dianhydride, 1,4,5,8-naphthalenetetracarboxylic dianhydride, 3,4,9,10-perylenetetracarboxylic dianhydride, bicyclo(2,2,2)octo-7-ene-2,3,5,6-tetracarboxylic dianhydride, ethylenediaminetetraacetic dianhydride, and diethylenetriaminepentaacetic dianhydride;

wherein the adduct is a non-oligomeric and non-polymeric imide.

10. The phase change ink carrier composition of claim 9 wherein the polyanhydride/mono-amine adduct is selected from polyanhydride-based amide adducts and polyanhydride-based imide adducts and mixtures thereof.

11. The phase change ink carrier composition of claim 9 wherein the polyanhydride/mono-amine adduct is made from a dianhydride.

12. The phase change ink carrier composition of claim 11 wherein the dianhydride is an aromatic dianhydride.

13. The phase change ink carrier composition of claim 12 wherein the aromatic dianhydride is benzophenone tetracarboxylic dianhydride.

14. The phase change ink composition of claim 9 wherein the phase change ink carrier composition further has components selected from the group consisting of urethanes, ureas, mixed urethane/urea resins, and mono-amides and combinations thereof.

15. The phase change ink carrier composition of claim 9 further including a wax selected from the group consisting of an ester, an amide, a natural wax, a synthetic wax and mixtures thereof.

16. The phase change ink carrier composition of claim 9 further including an antioxidant.

17. A phase change ink composition comprising the phase change ink carrier composition of claim 9 and at least one compatible colorant.
