Abstract
The present invention is directed to a printing ink composition containing the reaction product of 5 to 100 parts by weight of a phenolic resin and about 100 parts by weight of a resin modified with an acid. The phenolic resin is prepared by condensing an appropriate 4-9 carbon alkylphenol with formalin. The modified resin is prepared by reacting 1 to 15 parts by weight of an appropriate unsaturated carboxylic acid and/or anhydride with about 100 parts by weight of the reaction product of 5 to 100 parts by weight straight-chain .alpha.-olefin with about 100 parts by weight of an appropriate pentacyclic compound, such as cyclopentadiene and/or dicyclopentadiene.
