Photopolymerisationsverfahren

摘要

A process for the photopolymerization of ethylenically unsaturated organic compounds, is disclosed, which comprises irradiating with actinic light a composition comprising a photopolymerizable ethylenically unsaturated organic compound and as a photopolymerization initiator a compound containing at least one diazosulphone group, said compound corresponding to one of the formulae: X-SO2-N=N-Y and X'-SO2-N=N-Z-N=N-SO2-X'
