Substituted naphthacenediones of the formula I <IMAGE> (I) in which R1 to R8 are H and at least one of R1 to R8, for example R2 and R3 or R2 and R6, are, for example, C1-C20alkoxy, C1-C20alkenoxy, C1-C20-alkylsulfinyl, -CN, -CF3, -NO2, -Si(CH3)3 or -COO(C1-C12alkyl), 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.
