Light-sensitive ethylenically unsaturated materials containing benzanthrones and novel sensitizers

Abstract

Abstract A light-sensitive composition comprising addition polymerizable ethylenically unsaturated double bond-containing compounds and a photopolymerization initiator comprising (1) at least one compound selected from the group consisting of benzanthrone, substituted benzanthrones (the substituents of which include halogen atoms, alkyl groups having 1 to 5 carbon atoms and alkoxy groups having 1 to 5 carbon atoms), 1,2-benzanthraquinone and substituted benzanthraquinones (substituents of which include halogen atoms, alkyl groups having 1 to 5 carbon atoms and alkoxy groups having 1 to 5 carbon atoms) and (2) at least one compound selected from the group consisting of 4,4'-di-substituted amino-benzophenones represented by the following general formula (a), p-substituted amino-benzaldehyde derivatives represented by the following general formula (b), 2-(p-substituted amino-phenyl)-1,3-dioxolanes represented by the following general formula (c), 4,4'-bis(substituted amino)-N-benzylideneanilines represented by the following general formula (d) and 2-[4-(substituted amino)cinnamoyl]naphthalenes represented by the following general formula (e): ##STR1## wherein R and R', which may be the same or different, each represents a methyl group or an ethyl group, and R 0 represents a hydrogen atom, a hydroxy group, a --CR 1 R 2 R 3 group, where R 1 , R 2 and R 3 , which may be the same or different, each represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, or an --OR 4 group, where R 4 represents an alkyl group having 1 to 5 carbon atoms.
