A photopolymerizable composition comprising at least one polymerizable ethylenically unsaturated material, for example, an ethylenically unsaturated monomer, and a photosensitive catalyst comprising A. AT LEAST ONE PHOTOSENSITIZER HAVING THE STRUCTURE where X is >C=O, >CR1R2 or >CR3OR4, especially >C=O, R1 to R4 and hydrogen or hydrocarbyl groups, n is 0 or 1, and the groups A are hydrocarbyl or substituted hydrocarbyl groups, the groups A being aromatic or substituted aromatic when n is 1 and X is >CR1R2 and when n is 0, and B. AT LEAST ONE REDUCING AGENT, FOR EXAMPLE, AN AMINE OR A PHOSPHINE, CAPABLE OF REDUCING THE PHOTOSENSITIZER WHEN THE PHOTOSENSITIZER IS IN AN EXCITED STATE.
