摘要：
The present invention relates to a dental composition comprising a polymerization initiator system comprising an aromatic tertiary phosphine compound, as well as to a use of said aromatic tertiary phospine compound for the preparation of a photocurable dental composition. In particular, the present invention relates to a dental composition comprising (a) one or more compounds having at least one polymerizable double bond； (b) a polymerization initiator system comprising (b1) a sensitizer； and (b2) an aromatic tertiary phosphine compound of the following formula (I): Z-R (I) wherein Z is a group of the following formula (II) R(Ar)P-(II) wherein R1 represents a substituted or unsubstituted hydrocarbyl group； Ar represents a substituted or unsubstituted aryl or heteroaryl group； R is an aryl group, which may be substituted by one or more groups selected from a hydroxyl group, an amino group, a NR2R3 group (wherein R2 and R3, which may be the same or different, are selected from C1-6 alkyl groups), a carboxyl group, and a group having a polymerizable double bond； wherein the group R and Ar may be substituted by one or more groups selected from a hydroxyl group, an oxo group, a NR2R3 group (wherein R2 and R3, which may be the same or different, are selected from a hydrogen atom and C1-6 alkyl groups), a carboxyl group, and a group having a polymerizable double bond, and L may be substituted by one or more groups selected from a hydroxyl group,an oxo group, a NR2R3 group (wherein R2 and R3, which may be the same or different, are selected from a hydrogen atom and C1-6 alkyl groups), a carboxyl group, and a group having a polymerizable double bond.
