Printing inks for offset and / or high-pressure printing with NIR absorbers as well as NIR absorbers soluble in offset and / or high-pressure inks

摘要

Printing inks for offset and / or high-pressure, which contain NIR absorbers, and the solubility of the NIR absorber in the printing ink is at least 0.1 wt .-%. NIR absorber consisting of cyanine cation with an anion which has long-chain alkyl or aralkyl groups. Use of such printing inks for printing processes in which the curing of the printing ink is assisted by the use of IR lasers. NIR absorber of a cyanine cation with an anion which has long-chain alkyl or aralkyl groups.
