Dental composition

Abstract

The present invention is related to a dental composition comprising: (a) at least one polymerizable monomer having at least one ethylenically unsaturated group; (b) a radical initiator system comprising (i) a photosensitizer having an absorption maximum ranging from 400 nm to 800 nm; (ii) a coinitiator; and (iii) a compound of the following formula (1): wherein R1 and R2, which may be the same or different, independently represent a hydrogen atom, a C1-6 alkyl group, or a C1-6 alkoxy group; R3 and R4, which may be the same or different, independently represent a hydrogen atom, or a C1-6 alkyl group, or R3 and R4 may represent a bond so that the carbon atoms to which R3 and R4 are bonded are linked by a double bond; R5 and R6, which may be the same or different, independently represent a hydrogen atom, or a C1-6 alkyl group, or R5 and R6 may represent a bond so that the carbon atoms to which R5 and R6 are bonded are linked by a double bond; L represents a single bond or a group —CRH—, wherein R may be a hydrogen atom, a C1-6 alkyl group, or a C1-6 alkoxy group; n and m, independently are integers of 1 to 6.

Dependencies are inferred from the claim text.
