Abstract

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.
