Abstract
Phenolic-resin-modified natural resin acid esters, a process for their preparation and their use as binder resins printing inks. Phenolic-resin-modified natural resin acid esters obtained by reaction of PA1 A) natural resins and natural resin acids, PA1 B) mononuclear and polynuclear alkylolizable phenols, PA1 C) aldehydes and aldehydes acetals, PA1 D) aliphatic, cycloaliphatic and araliphatic polyols, PA1 E) calcium compounds and/or zinc compounds and PA1 F) optionally ethylenically unsaturated hydrocarbon resins, at a temperature of 100.degree. to 250.degree. C., and subsequent removal of the water by azeotropic distillation with an entraining agent at 200.degree. to 300.degree. C.
