NON-LEACHABLE U.V. ABSORBER AND DENTAL RESTORATIVE MATERIAL

摘要

The adduct of glycidyl methacrylate and phenyl salicylate is found to be a valuable copolymerizable and hence non-leachable stabilizer for acrylate monomers against color change induced by ultra-violet light in dental compositions of inorganic particulate material as filler, N,N-bis(hydroxyalkyl)aromatic amine as potential accelerator and acrylate or methacrylate esters of aromatic or unsaturated lower aliphatic diacid hemiesters or diphenolic ethers with di- or tri-primary diols or triols as vehicles or binders. Polymerization is initiated in these combinations by free-radical generating catalysts.
