The present invention discloses an adhesive for orthodontic attachments, which contains (A) a polymerizable monomer, (B) a polymerization initiator and (C) a fluorescent dye and, when cured, exhibits a fluorescence spectrum having a peak at 400 to 800 nm. As the polymerization initiator (B), there is preferably used a compound which generates a radical through the transfer of hydrogen between two components, or a compound which generates a radical species through intramolecular cleavage. As the fluorescent dye (C), a coumarin type dye is used preferably.
本发明公开了一种用于正畸附件的粘合剂,它含有 (A) 一种可聚合单体,(B) 一种聚合引发剂和 (C) 一种荧光染料,当固化时,其荧光光谱的峰值在 400 至 800 纳米之间。作为聚合引发剂(B),最好使用通过两个组分之间的氢转移产生自由基的化合物,或通过分子内裂解产生自由基的化合物。作为荧光染料(C),最好使用香豆素类染料。
