Tunable fluorescent UV curable gel inks containing fluorescent monomers for food packaging applications

摘要

A radiation-curable phase-change ink composition having at least one radiation curable fluorescent co-monomer and a gallant is disclosed. The radiation-curable phase-change ink composition offers both document security features as well as potential brand highlight features. The radiation-curable phase-change ink composition combines the unique attributes of the UV curable gel system, with its tremendous substrate latitude, with the ability to add tunable fluorescent effects without the safety concerns of small molecule fluorescent additives. Exemplary ink compositions include a first co-monomer, least one radiation curable fluorescent co-monomer, and a gellant. Methods for making and using these ink compositions and ink compositions are also provided.
