Abstract

The present invention relates to a dental composition comprising a specific polymerizable compound and a polymerization initiator system. Furthermore, the present invention relates to the specific polymerizable compound as such and its use in a dental composition. The specific polymerizable compound of the present invention has an N-allyl (meth)acrylamide group, which nitrogen atom is substituted with an alkyl or alkenyl group optionally substituted by a group selected from a hydroxyl group, a C1-4 alkoxy group, a tertiary amino group and a carboxyl group, wherein 1 to 8 carbon atoms in the main chain of the alkyl or alkenyl group may independently from each other be replaced by a heteroatom selected from an oxygen atom and a sulfur atom.

A dental composition comprising

(a) a polymerizable compound of the following formula (I):
wherein
R represents a straight chain or branched C2-18 alkyl or alkenyl group, which may be substituted by a group selected from a hydroxyl group, a C1-4 alkoxy group, a tertiary amino group, and a carboxylic acid group, and wherein 1 to 8 carbon atoms in the main chain of the C2-18 alkyl or alkenyl group may independently from each other be replaced by a heteroatom selected from an oxygen atom and a sulfur atom, and
R* represents a hydrogen atom or a methyl group;
and
(b) a polymerization initiator system.
