摘要:
A pigmented phase change ink composition comprising an ink vehicle, a dispersant, and pigment particles wherein the dispersant is a chemical compound of formula: wherein R1 is an alkyl group, aryl group, alkylaryl group or arylalkyl group with at least 23 carbon atoms, R2 is an alkylene group, arylene group, alkylarylene group or arylalkylene group with at least 2 carbons and X is a quaternary ammonium salt. The ink can be resistant to substantial aggregation and settling of the pigment particles in the melt and even when exposed to freeze thaw cycles.
摘要:
A phase change ink having an ink vehicle, at least one colorant at least one triamide and at least one bis-urethane. The at least one triamide and at least one bis-urethane assist in dispersing colorants, such as pigments like carbon black, in non-polar ink vehicles. Also, disclosed are methods of making such phase change inks.

摘要:
A solid ink composition comprising at least one crystalline oxazoline compound and at least one amorphous component derived from a polyol, and a colorant and optional viscosity modifier, which are suitable for inkjet printing, including printing on coated paper substrates. In embodiments, the solid ink formulation comprises a blend of an amorphous and crystalline components which provides a solid ink with excellent robustness when forming images or printing on coated paper substrates.
