摘要： A vehicle for lithographic printing ink is prepared by using an improved binder resin of petroleum resin-modified phenol resin, in which the melt viscosity of the binder resin is maintained below a certain level to improve the workability in polymerization process and the misting in printing press is reduced by using the improved binder resin. In the preparation of the binder resin, acid modified hydrocarbon resin (A) is prepared by reacting components (a) mainly comprising five-membered cyclic compounds or their Diels-Alder reaction products with the components (b) comprising unsaturated carboxylic acids or their anhydrides, and said acid modified hydrocarbon resin (A) is then reacted with phenol resin (B) in which portions of the phenol resin are fed one after another, thereby producing said binder resin having the properties of: high weight average molecular weight, low melt viscosity and low ratio of melt viscosity to solution viscosity.
