ABSTRACT:
The specification discloses a lithographic ink vehicle containing an addition copolymer of ethylenically unsaturated monomers having a critical calculated second order transition temperature (T.sub.g), and a critical molecular weight, utilizing as the essential solvents in the ink a predominantly aliphatic hydrocarbon having a kauri-butanol value of between about 18 and 31, preferably between about 21 and 28, in which the polymer must be soluble. Among the preferred monomers are isobornyl methacrylate and isobutyl methacrylate. Other ethylenically unsaturated monomers may be included, particularly functional monomers in small amounts having acid or amine groups.
