ABSTRACT:
Synthetic resins suitable for use in printing ink compositions are produced by reacting a mixture consisting essentially of (a) a predominant amount of dicyclopentadiene and lesser amounts of (b) at least one hydrocarbon selected from the group consisting of monoolefins, diolefins, and polyenes each having more than five carbon atoms, and having no aromatic rings, and (c) at least one member selected from the group consisting of fatty acid-containing materials and rosin acid-containing materials. Additional synthetic resins suitable for use in printing ink compositions are produced by reacting components (a) to (c) above with an ethylenically unsaturated lower aliphatic dicarboxylic acid or anhydride, such as maleic anhydride.
