FIELD: printing industry.
SUBSTANCE: invention relates to inks sensitive to infra-red radiation (IR), finding application for tracking and authentication of different objects. Inks with IR sensitivity fasten under the influence of ultraviolet is described, including: curing (UV) light matrix, which includes any number of epoxy and/or acrylate oligomers; UV photoinitiator, and IR-sensitive dye. System for the covering of said UV drying inks with IR sensitivity is also described.
EFFECT: offered inks in comparison with known not fasten infrared-sensitive inks possess durability and water resistance and improve the environment by excluding emissions of the solvent.
