Phase change ink formulation including malic acid derivatives as amorphous materials

摘要

A phase change ink composition suitable for ink jet printing, including printing on coated paper substrates. The present embodiments provide an ink composition including a component that is substantially amorphous, the component comprising at least one non-ester material and at least one ester of malic acid having a formula of;
wherein R1 and R2 each, independently of the other, is an alkyl group, and further wherein the alkyl portion can be straight, branched or cyclic, saturated or unsaturated, substituted or unsubstituted, having from 1 to about 40 carbon atoms, an substituted or unsubstituted aromatic or heteroaromatic group, and mixtures thereof.

1. A phase change ink composition comprising an amorphous component comprising:
at least one non-ester material and at least one ester of malic acid having a formula of wherein R1 and R2 each, independently of the other, is an alkyl group, and further wherein the alkyl portion can be straight, branched or cyclic, saturated or unsaturated, substituted or unsubstituted, having from 1 to about 40 carbon atoms, an substituted or unsubstituted aromatic or heteroaromatic group, and mixtures thereof, wherein the at least one non-ester material and the at least one ester of malic acid are reaction products from the malic acid and one or more alcohols, wherein the component has a viscosity of from about 1 to about 100 cps at a temperature from about 100° C. to about 140° C.
