Abstract
Abstract Iron (II)-aromatic compound complexes mixed with electron acceptors as an oxidizing agent are suitable initiators for the polymerization by irradiation of organic material which can be polymerized by cations and/or free radicals. The composition composed of the polymerizable material and of the initiator mixture is suitable for the production of protective coatings and can be used as a photographic recording material.
