Abstract of the Disclosure The present invention encompasses a urethane-modified rosin ester which is derived from an isocyanate and a hydroxyl-functional rosin esterification product of a dimerized rosin. The urethane- modified rosin esters, having a high softening point and good compatibility with hydrocarbon solvents, good gelability and good squalene resistance, are particularly suitable as binders for inks such as fast conversion lithographic inks.
