  • Dental composition
    Patent number: 10512594
    Abstract: The present invention relates to a dental composition comprising an initiator system comprising a sensitizer compound having an acylsilyl- or acylgermyl-group and a specific coinitiator compound. The present invention also relates to an initiator system consisting essentially of the sensitizer compound having an acylsilyl- or acylgermyl-group and a coinitiator compound wherein a C—H bond dissociation energy is less than 95 Kcal/mol. Furthermore, the present invention relates to the use of this initiator system for the preparation of a dental composition.
