Abstract

A printing ink or varnish having a binder comprising isopropylmethacrylate and hydrophilic comonomers, particularly unsaturated carboxylic acids, their hydroxyalkyl esters, or a mixture thereof; preferably in combination with cellulose esters such as nitrocellulose, as an additional binder. The ink or varnish also contains dissolved or undissolved dyes, as well as a lower alkyl alcohol solvent. The printing and coatings thus produced are characterized by hardness and a high sealing stability.
