Abstract
Cyclopentadiene-modified alkyd resins obtained by reaction of naturally occurring, unsaturated fatty acid esters with cyclopentadiene compounds under pressure, transesterification of the resulting adducts with polyols which contain at least three hydroxyl groups, and esterification with aromatic or cycloaliphatic polycarboxylic acids or anhydrides thereof. These resins are employed in the preparation of printing inks for offset printing. The novel resins impart an improved gloss to these printing inks.
