Abstract

Modified cyclopentadiene resins comprising essentially a) 20 to 80% by weight of cyclopentadiene compounds, b) 1 to 40% by weight of natural resin acids and c) 31 to 70% by weight of phenol resins. These compounds are suitable as binder resins for printing inks. They are distinguished by excellent compatibility with aromatics-free mineral oils and with vegetable oils.
