Abstract
A modified cyclopentadiene resin which comprises (a) 40 to 90% by weight of units of monomeric or oligomeric cyclopentadiene and/or its alkyl-substitution products, (b) 1 to 30% by weight of resols, (c) 5 to 40% by weight of non-aromatic, unsaturated monocarboxylic acids having 8 to 26 carbon atoms, (d) 0 to 10% by weight of .alpha.,.beta.-olefinic, unsaturated dicarboxylic acid units, (e) 0 to 20% by weight of other copolymerizable monomers and/or (f) 0 to 3% by weight of a metal compound from the groups IIa, IIb or IIIa of the periodic system, the sum of the components (a) to (f) always being 100% by weight, a single-stage process for its preparation, and the use of the modified cyclopentadiene resins as binders for printing inks, particularly for gravure inks.
