The present invention relates to a polyurethane, which is particularly suitable as binder for a printing ink, which is obtainable by reacting: a) a polyol component including: i) at least one polytetramethylene glycol, ii) at least one diol having a molecular weight of not more than 200 g/mol being different from polytetramethylene glycol, iii) at least one trivalent or higher-valent alcohol having a molecular weight of not more than 6000 g/mol, b) an isocyanate component including at least one organic diisocyanate compound and c) at least one di-functional amine compound and at least one mono-functional amine compound.

Polyurethane being suitable as binder for a modular printing ink system

An offset printing ink is provided which comprises a colophony-modified phenolic resin and at least one component selected from the group consisting of (A) a maleic resin, (B) a modified hydrocarbon resin, (C) a colophony resin ester and mixtures thereof. The ink further comprises a water-insoluble fatty acid ester of a multivalent alcohol which has a high steric spatial requirement, and/or ethinol.

Low-migration, low-odor and low-swelling sheet offset printing ink
