Abstract
Heterogeneous photoinitiator in microparticle form, which consists of a finely divided substrate material to which identical or different photoinitiators are covalently bonded. The photoinitiators are suitable for the radiation-induced polymerization of photopolymerizable or photocrosslinkable monomers for the production of moldings, protective coats and relief images.
