ABSTRACT:
A process for producing a novel modified resin, which comprises reacting (I) a hydroxyl-containing resin with (II) a polyisocyanate compound, said resin (I) being prepared by reacting (a) the reaction product of a cyclopentadiene resin, a higher fatty acid ester having a conjugated double bond and an .alpha.,.beta.-unsaturated dicarboxylic acid anhydride with (b) a hydroxyl group-imparting agent; a modified resin obtained by the aforesaid process; and a printing ink comprising the modified resin as a vehicle component.
