Abstract
The invention provides a novel ink for dry planographic printing. The new ink is based on a vehicle containing the reaction product of an oil-modified alkyd resin, a rosin-modified phenolic resin, and a diisocyanate and also a high viscosity silicone oil. The new ink can be used with planographic plates having an oleophobic surface and does not adhere to the non-image areas.
