Abstract
Abstract A process for producing a novel modified resin, which comprises reacting (I) the reaction product of 98 to 35% by weight of a cyclopentadiene resin, 2 to 65% by weight of a higher fatty acid ester having a conjugated double bond and 0 to 30% by weight of an α,β-unsaturated dicarboxylic acid anhydride, with (II) at least one vinyl monomer selected from the group consisting of vinyl aromatic compounds and unsaturated monocarboxylic acid esters; and a vehicle component composition for printing inks comprising the aforesaid modified resin.
