Abstract

A solid ink composition comprising an amorphous component, a crystalline material, and optionally, a colorant, which are suitable for ink jet printing, including printing on coated paper substrates, and methods for making the same. In embodiments, the crystalline and amorphous components are synthesized from an esterification reaction of tartaric acid with an alcohol.
