A binder for use in gravure printing ink formulations comprising a modified rosin ester resinate prepared by forming a rosin-dienophile adduct, reacting the adduct with a polyfunctional hydroxy compound to form an ester and reacting with an acrylic-containing polymer to form a hard rosin ester. The polymer-modified rosin ester resinate is formed by reacting the prepared hard rosin ester with a rosin-dienophile adduct and an acrylic-containing polymer, reacting the product thereof with reactive zinc, followed by a reaction with lime, dehydrating the resinate product by refluxing, and adjusting its viscosity with a hydrocarbon solvent.
