Zusammenfassung:A printing ink formulation capable of being utilized in driography comprising (a) a varnish comprising at least one polymer having a weight average molecular weight of at least about 25,000 and a solvent therefor, and (b) at least about 5.0 percent by weight, based on the varnish, of at least one non-reinforcing filler. Preferably, the ink also contains a minor amount of a low surface tension fluid which is incompatible with the varnish.
