摘要 |
<p>Oxidatively crosslinking, essentially isocyanate-free urethane resins obtainable by reacting A) 100 parts by weight of an ester made from (a1) an aliphatic C3-C8-alcohol containing at least three hydroxyl groups and (a2) an unsaturated C8-C40-fatty acid and (a3) if desired an aliphatic or aromatic polycarboxylic acid having 4-20 carbon atoms, or anhydrides thereof, in amounts of up to 60% by weight, based on the fatty acid a2) where the ester contains sufficient free hydroxyl groups to correspond to an OH number of 50-150 mg KOH/g, with B) (b1) 3-120 parts by weight of C5-C15-polyhydroxycarboxylic acids containing at least two hydroxyl groups and (b2) 10-100 parts by weight of an aliphatic or cycloaliphatic polyisocyanate, or mixtures thereof, at 50-150 DEG C in the presence of apolar solvents which are inert towards isocyanates. These resins are suitable for use as constituents of printing inks.</p> |
