Abstract

Radiation-curable compositions of Pigment Violet 23 are described which can be used advantageously in UV inks for inkjet printing machines. Soiling containing such UV inks, especially within inkjet printing machines, can be removed particularly easily in a contactless procedure with conventional cleaners. The radiation-curable compositions described contain at least one modified Pigment Violet 23 which carries at least one polar functional group of the formula (I): —X-E (I)
