Abstract
Abstract A process for producing a novel modified resin, which comprises reacting (I) the reaction product of (a) an adduct of a cyclopentadiene resin with an α,β-unsaturated dicarboxylic acid anhydride, with (b) an adduct of a higher fatty acid ester having a conjugated double bond with an α,β-unsaturated dicarboxylic acid anhydride, with (II) a polyamine having at least two primary or secondary amino groups; and a vehicle component composition for printing inks comprising the aforesaid modified resin.
