Beschreibung
Zusammenfassung:	A resinous binder is disclosed which comprises (a) a major proportion of a metal rosin resinate, (b) a minor proportion of a poly(ethylene-vinyl acetate) type polymer having a weight average molecular weight of at least 50,000, and optionally (c) a solvent; said poly(ethylene-vinyl acetate) type polymer being present in the resinous binder in an amount which is effective to increase the dilution of the resinous binder as compared to the dilution of the metal rosin resinate alone. A method for the preparation of the resinous binder is described. Also disclosed is a printing ink composition which comprises a solvent, a colorant and a binder system wherein all or a portion of the binder system consists of the resinous binder of this invention. The use of the resinous binder of this invention in ink compositions results in significant dilution improvement without adversely affecting other desirable properties.
