Abstract
Abstract In a photopolymerizable composition comprising (a) at least one ethylenically unsaturated photopolymerizable monomer. (b) at least one photoinitiator selected from organic mono- and/or di-carbonyl compounds and (c) a photoactivator, the improvement which comprises employing as said photoactivator at least one alkylaminoarylsulphonyl compound of the formula ##STR1## in which R 1 and R 2 each independently is a hydrogen atom or an alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, aralkyl or alkaryl group which has 1 to 11 carbon atoms and is optionally substituted by at least one hydroxyl, amino, epoxy, urethane, urea, ether of ether group, or R 1 and R 2 together form a 3- to 6-membered ring, which optionally contains nitrogen, oxygen or sulphur as a hetero-atom, R 3 independently of R 1 , has any of the meanings given for R 1 or is a group of the formula ##STR2## R 4 and R 5 each independently is a hydrogen atom, an alkyl or alkenyl group which has 1 to 10 carbon atoms and is optionally substituted by halogen, or a halogen atom, or R 4 and R 5 are in ortho-positions relative to one another and, together with the aromatic nucleus, form a 4- to 8-membered ring, and X is an alkyl or alkenyl group which has 1 to 10 carbon atoms and is optionally substituted by a hydroxyl, amino, urethane, urea or ester group, or is a group of the formula ##STR3## wherein R 6 and R 7 , independently of R 1 and R 2 , have any of the meanings given above for R 1 and R 2 . The compositions are especially useful for dental prostheses, fillings and coatings since they are not irritating to human tissue.
