Verbindungen der Formel I RG-A-IN (I) mit IN eine Fotoinitatorgrundstruktur, A eine Spacergruppe und RG eine funktionelle reaktive Gruppe und den im Hauptanspruch hierfür angegebenen Bedeutungen können als coreaktive Fotoinitiatoren für die Fotopolymerisation ethylenisch ungesättigte Verbindungen enthaltender Systeme eingesetzt werden. Compounds of the formula I RG-A-IN (I> where IN is the basic structure of a photoinitiator, A is a spacer group and RG is a functional reactive group as defined in the main claim, can be employed as coreactive photoinitiators for the photopolymerisation of systems containing ethylenically unsaturated compounds.
