Light-curing compositions characterized by a new amine accelerator to improve color stability and thereby reduce polymerization stress

摘要

A photopolymerizable dental composition comprising: ** Formula ** (i) aromatic tertiary diamines, (ii) a photosensitizer, and (iii) one or more (meth) acrylate monomers as polymerizable resins, wherein said tertiary-diaomatic diamine has a biphenyl moiety Rotated having the structure in which R 2 and R 3 are independently of each other alkyl having C 1 to C 18 carbon atoms, R and R 1 are independently hydrogen or halogen; alkyl, alkoxy or alkylthio having 1 to 18 carbon atoms; or phenyl and / or substituted phenylalkoxy or alkylthio having 1 to 18 carbon atoms.
