ABSTRACT:
An ink vehicle composition is provided comprising a polymeric type resin binder component and a terpene dimer oil. In an alternate embodiment the compositions further include an additional oil selected from linseed oil, soya bean oil, tung oil, or other oils having drying characteristics defined by an Iodine value greater than 120. Advantageously, the compositions contain a reduced amount of petroleum distillate solvent and lower volatile organic compounds (VOC) than conventional ink vehicles. As an ink vehicle the compositions are further incorporated into ink formulations. The varnish compositions are also used as an overprint varnish on a substrate surface.
