Abstract
Abstract Printing ink compositions preferably comprising epoxidized soybean oil acrylate or certain derivatives thereof and a radiation sensitizer having a triplet energy between about 42 and 85 kcal/mole. Also, the method of printing with such inks comprising exposing the inks to an amount of actinic radiation effective to polymerize the inks to a non-offsetting state and the printed substrate produced by this method. Novel alkyd-derived compositions used as vehicles for the above printing ink compositions and preferably comprising the reaction product of 1. AN ALKYD FORMED FROM TRIMETHYLOL PROPANE, TALL OIL FATTY ACID, AND ADIPIC ACID WITH 2. THE REACTION PRODUCT OF TOLUENE DIISOCYANATE AND THE MONOACRYLIC ACID ESTER OF ETHYLENE GLYCOL. The method of coating with such compositions comprising exposing them, in combination with a radiation sensitizer, to an amount of radiation effective to polymerize them to a non-offsetting state.
