Abstract
A process for producing an animal or vegetable oil-modified and rosin-modified phenolic resin for printing inks, which comprises: PA1 [I] reacting (a) a resol-type phenol/formaldehyde initial condensation product, (b) an animal or vegetable oil having an iodine value of 100 to 210 or containing a hydroxyl group, (c) a rosin and (d) an alchohol, and if required, (e) an acid or (f) a hydrocarbon resin; or PA1 [II] reacting the condensation product (a) and the animal or vegetable oil (b) with a rosin ester obtained by the reaction of the rosin (c) and the alcohol (d) and if required, the acid (e) or the hydrocarbon resin (f) in advance.
