Abstract

Aqueous and radiation-curable printing varnishes and printing inks, are disclosed which contain special polyoxyalkylene polysiloxane copolymers. These printing varnishes and printing inks have improved scratch resistance, a higher gliding ability and an extremely low tendency to foam, so that the production of printing inks proceeds without problems and, at the same time, an optically attractive typography can be obtained.
