Abstract

A phase change ink carrier composition comprising at least one anhydride/amino alcohol based adduct which is a reaction product of at least one anhydride and at least one amino alcohol, wherein the reaction product is an ester material or an amide material, but not an ester-amide material.

Claims

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

wherein said at least one anhydride/amino alcohol inclusive reaction product is an ester or an amide, but not an ester-amide.

2. The phase change ink carrier composition of claim 1 wherein the anhydride/amino alcohol inclusive reaction product is selected from anhydride based mono ester adducts, anhydride based diester adducts, anhydride-based mono-amide adducts, anhydride-based diamide adducts, and anhydride-based imide adducts and combinations thereof.

3. The phase change ink carrier composition of claim 1 wherein the anhydride/amino alcohol inclusive reaction product is made from a cyclic anhydride.

4. The phase change ink carrier composition of claim 3 wherein the cyclic anhydride is an alkylsuccinic anhydride or an alkenylsuccinic anhydride.

5. The phase change ink carrier composition of claim 1 wherein the at least one amino alcohol is selected from the group consisting of monoalkanol amines, dialkanol amines and trialkanol amines and combinations thereof.

6. The phase change ink carrier composition of claim 1 wherein the amino alcohol is selected from the group consisting of ethanolamine;

3-amino-1,2-propanediol;

serinol;

2-amino-2-methyl-1,3-propanediol;

tris(hydroxymethyl)-aminomethane;

1-amino-1-deoxy-D-sorbitol;

diethanol amine;

diisopropanolamine;

N-methyl-N,N-diethanol amine;

triethanol amine;

N,N,N′

,N′

-tetrakis (2-hydroxypropyl) ethylenediamine; and

combinations thereof.

7. The phase change ink carrier composition of claim 1 further including a wax selected from the group consisting of an ester, an amide, a natural wax, a synthetic wax and mixtures thereof.

8. The phase change ink carrier composition of claim 1 further including an antioxidant.

9. A phase change ink composition comprising the phase change ink carrier composition of claim 1 and at least one compatible colorant.

10. The phase change ink composition of claim 1 wherein the phase change ink carrier composition further has a component selected from the group consisting of urethanes, ureas, mixed urethane/urea resins, and mono-amides and combinations thereof.

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

wherein functional groups of said at least one anhydride/amino alcohol inclusive reaction product consist of only ester groups or only amide groups.
