Improved polyol esters of phenol-rosin condensates and polyimide/polyamide derivatives thereof and their method of manufacture are disclosed as well as their applications as varnishes for lithographic inks and in pigment dispersion (flushing). Advantages of ink varnishes comprising these derivatives include higher water yields, increased gloss, transparency, and color strength, as well as reduced bronzing in both pigment concentrates and finished lithographic inks.
