    摘要: Photopolymerization initiator for the visible light-polymerizing adhesives; and the visible light-polymerizing adhesives comprising the photopolymerization initiator, an aliphatic tertiary amine and a radical polymerizing monomer. The visible light-polymerizing adhesive of the invention has good transparency without coloring after photopolymerization as well as good adhering activity. It also has colorless, good transparency after photopolymerization and good adhering activity in an UV irradiation test, as well as excellent light resistance showing very little color change and deterioration in an UV irradiation test. The visible light-polymerizing adhesive of the invention is also excellent in photopolymerizing activity. Furthermore, the visible light-polymerizing adhesive of the invention has photopolymerizing activity not only to visible light but also to near-UV. It hardly has problems of such decrease in transparency caused by both kinds of lights as coloring and color change.

    摘要: A bracket for orthodontics having a bracket body made of a composite resin material and a thin layer of a synthetic resin material in a dental adhesive. The synthetic resin layer is laminated on the base surface of the bracket body in such a manner that the composite resin material of the bracket body and the synthetic resin of the thin layer are mingled with each other at the boundary therebetween. The thin resin layer is composed of polymethyl methacrylate having an average molecular weight of 1000,000 or less or a polymethacrylate copolymer.
