Abstract
Naphthacene-5,12-diones which are substituted by at least one organic thio radical are not only photoinitiators for the photopolymerization but also sensitizers for the photodimerization of ethylenically unsaturated compounds. Compositions made of these naphthacene-5,12-diones and ethylenically unsaturated compounds are suitable for the preparation of printing inks, paints, printing plates, resist materials or as image recording material.
