Substituted naphthacenediones of the formula I ##STR1## in which R.sup.1 to R.sup.8 are H and at least one of R.sup.1 to R.sup.8, for example R.sup.2 and R.sup.3 or R.sup.2 and R.sup.6, are, for example, C.sub.1 -C.sub.20 alkoxy, C.sub.1 -C.sub.20 alkenoxy, C.sub.1 -C.sub.20 -alkylsulfinyl, --CN, --CF.sub.3, --NO.sub.2, --Si(CH.sub.3).sub.3 or --COO(C.sub.1 -C.sub.12 alkyl), are suitable, when incorporated into polymers having hydroxyalkyl groups, for currentless deposition of metals onto the polymer surface. They are in some cases suitable as photoinitiators.
摘要:
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.
