Abstract
A solid ink composition comprising an amorphous component, a crystalline component, and optionally, a colorant, which are suitable for ink jet printing, including printing on coated paper substrates. In embodiments, the crystalline component is synthesized from an esterification reaction of tartaric acid.
Claims19
A phase change ink comprising:
- at least an amorphous component, wherein the amorphous component is selected from the group consisting of di-L-menthyl L-tartrate, di-DL-menthyl L-tartrate, di-L-menthyl DL-tartrate, di-DL-menthyl DL-tartrate, and any stereoisomers and mixtures thereof;
- and
- at least a crystalline component, wherein the crystalline component is an ester of tartaric acid having a formula of
- wherein R1 and R2 each, independently of the other, is selected from the group consisting of alkyl group, wherein the alkyl portion can be straight, branched or cyclic, saturated or unsaturated, substituted or unsubstituted, having from 1 to 40 carbon atoms, or an substituted or unsubstituted aromatic or heteroaromatic group, and mixtures thereof, and further wherein the tartaric acid backbone is selected from L-(+)-tartaric acid, D-(−)-tartaric acid, DL-tartaric acid, or mesotartaric acid, and mixtures thereof.
