Claims
- 1. A phenolic-resin-modified natural resin acid ester prepared from compounds selected from the group consisting of
- A) natural resins and natural resin acids,
- B) mononuclear and polynuclear alkylolizable phenols,
- C) aldehydes and aldehyde acetals,
- D) aliphatic, cycloaliphatic and araliphatic polyols,
- E) calcium compounds and zinc compounds and
- F) ethylenically unsaturated hydrocarbon resins;
- by reaction of at least one compound of each of A) to E) and optionally F); at a temperature of 100.degree. to 250.degree. C.; and by subsequent removal of water by azeotropic distillation with an entraining agent at 200.degree. to 300.degree. C.
- 2. A process for preparing the phenolic-resin-modified natural resin acid ester as claimed in claim 1, comprising reacting 30 to 95% by weight of natural resins or natural resin acids from substance group A), 1 to 45% by weight, of phenolic components from substance group B) and 2 to 20% by weight of aldehyde components from substance group C), or optionally, instead of the components from substance groups B) and C) or as a proportion with these, up to 65% by weight of condensation products in a phenol-resol form prepared separately from compounds of substance groups B) and C), 1 to 20% by weight of polyol components from substance group D), 0.01% to 5% by weight, calculated as CaO and/or ZnO, of calcium compounds and/or zinc compounds from substance group E), 0 to 30% by weight of hydrocarbon resin components from substance group F) together with 0.01 to 20% by weight of an inert entraining agent, each time relative to the total amount of components employed.
- 3. Binder resins for printing inks comprising a phenolic-resin-modified natural resin acid ester as claimed in claim 1 and additives chosen from colophony, colophony ester, vegetable oils and polymers.
- 4. A binder resin of claim 3 wherein the additives are selected from the group consisting of phenolic resins, polyesters, alkyd resins, acrylic polymers, polystyrene, modified silica gels and modified cellulose derivatives and mixtures thereof.
- 5. A printing ink for illustration gravure printing containing a phenolic-resin-modified natural resin acid ester of claim 1 as binder resins.
