Abstract

A photopolymerizable coating agent made of (a) a low molecular weight epoxy-containing epoxy resin, (b) a high-molecular weight epoxy resin based on aromatic polyols and epichlorohydrin, (c) a light-sensitive ethylenically unsaturated monomer having terminal ethylene groups and (d) a photoinitiator and/or sensitizer, and, if desired, hardeners for epoxy resins. It is used for preparing temporary or permanent protective coatings and photographic relief images.
