Abstract
Photopolymerizable dental compositions are proposed which are curable with visible light and which apart from usual auxiliary substances and additives contain polymerizable monomers of the group of the poly-thiol compounds and of the group of the poly-ene compounds and a photoinitiator and which, in order to obtain a curing free from any smeary layer, contain at least 10% by weight poly-thiol compound(s), at least 10% by weight poly-ene compound(s) and 0.01 to 5% by weight of at least one acyl phosphine compound as photoinitiator. The compositions can advantageously be used as dental impression compositions.
