Abstract
Abstract The present invention encompasses a phenolic-modified rosin ester which is derived from a rosin esterification product of a dimerized rosin and a phenolic resin. The phenolic-modified rosin esters, having a high softening point and good compatibility with hydrocarbon solvents and good gelability, are particularly suitable as binders for inks such as lithographic inks.
