Abstract

Binding-agent solutions for printing inks include of resin and solvent that contain from 10 to 70% by weight of one or more aromatic polymers with a softening point above 120.degree. C. and from 90 to 30% by weight of a solvent mixture, consisting of a mineral-oil fraction with a boiling range of from 200 to 550.degree. C. and of an alkylaromatic mixture of mono-, di-, tri and tetraisopropyl naphthalenes, whose aromatic carbon content lies in the range of from 20 to 60% of the total carbon.
