Abstract
A rosin/hydrocarbon hybrid resin is disclosed to be prepared by reacting rosin with a phenolic compound and an aldehyde to form a phenol-modified rosin intermediate which is reacted with dicyclopentadiene at elevated pressure and temperature to form the rosin/hydrocarbon resin. The resin is particularly useful as a lithographic printing ink resin.
