Abstract

Resins for printing ink and particularly offset ink, are produced by reacting a resin obtained by heat polymerizing at least one of cyclopentadiene, dicyclopentadiene or their alkyl substituted derivatives with 1-3 carbons and an unsaturated alcohol or unsaturated alcohol ester of an organic acid at a temperature of 150-350.degree. C. in the presence or in the absence of an inert hydrocarbon solvent with a higher monohydric saturated fatty acid or higher monohydric unsaturated fatty acid or their mixtures to produce a resin having a softening point of 100.degree. C or more.
