摘要：
A photopolymerizable composition, which contains a polymeric binder, a compound which can be polymerized by free radicals and has at least one terminal ethylenic double bond and a photoinitiator combination comprising an N-heterocyclic compound, a thioxanthone derivative and a dialkylamino compound, is highly photosensitive and produces photoresist stencils with vertical side walls.
