The invention discloses a kind of adhesive for teeth-straightening members, it contains (A) polymerizable monomer, (B) polymerization initiator reaches (C) fluorescent coloring, wherein, when this adhesive for teeth-straightening members solidifies, observe the fluorescence spectrum that has the peak at 400～800nm.As (B) polymerization initiator, preferably use by between 2 compositions, carrying out the initiator that giving and accepting of hydrogen produces the initiator of free radical, produces the free radical kind by the intramolecularly cracking.As (C) fluorescent coloring, preferred coumarin series pigment. |
