  A photopolymerization initiator comprising (A) a photo acid-generating compound such as diaryliodonium salt (e.g., diphenyl iodonium, bis(p-chlorophenyl)iodonium, etc.,), (B) a photo oxidation radical-generating compound such as diarylketone compound, α-diketone compound or ketocoumarin compound, and (C) a fused polycyclic aromatic compound such as 1,4-dimethylnaphthalene, 1-methylanthracene, 9-methylanthracene, 9,10-dimethylanthracene or 9,10-diethylanthracene. The photopolymerization initiator makes it possible to efficiently polymerize the cationically polymerizable monomer by the irradiation with visible light.

  A transparent vessel is filled with a mixture solution containing a first photo-curable resin of a low refractive index and a second photo-curable resin of a high refractive index different in curing mechanism. When light at a wavelength capable of curing the first photo-curable resin but incapable of curing the second photo-curable resin is applied to the mixture solution through an optical fiber, the first photo-curable resin can be cured in a state in which the second photo-curable resin is enclosed in the cured first photo-curable resin. Because the refractive index increases according to curing, a self-condensing phenomenon can be generated so that an optical path portion is formed. The optical path portion emits leakage light to its surroundings to thereby form an outer circumferential portion. Then, all uncured resins in the mixture solution are cured. The outer circumferential portion containing a high percentage of the cured first photo-curable resin serves as a clad because the refractive index of the outer circumferential portion is lower than that of the optical path portion.

  在一个透明容器中装入混合物溶液，其中包含固化机理不同的低折射率第一光固化树脂和高折射率第二光固化树脂。当能固化第一光固化树脂但不能固化第二光固化树脂的波长的光通过光纤照射到混合物溶液中时，第一光固化树脂可在第二光固化树脂被固化的第一光固化树脂包裹的状态下固化。由于折射率随固化而增加，因此会产生自冷凝现象，从而形成光路部分。光路部分向周围发射漏光，从而形成外圆周部分。然后，混合物溶液中所有未固化的树脂都会固化。由于外圆周部分的折射率低于光路部分的折射率，因此含有高比例固化第一光固化树脂的外圆周部分可用作包层。

  A cationically curable composition for dental use containing a cationic polymerization initiator (I) and cationically polymerizable monomers (II), the cationically polymerizable monomers (II) containing an oxetane compound and an epoxy compound or an alkenyl ether compound at a ratio of amounts that satisfy the conditions expressed by the following formula,         (a x A) : (b x B) = 91 : 9 to 45 : 55    wherein A is a mol number of the oxetane compound, "a" is an average number of the oxetane functional group contained in one molecule of the oxetane compound, B is a mol number of the epoxy compound or the alkenyl ether compound, and "b" is an average number of the epoxy functional group contained in one molecule of the epoxy compound or an average number of the alkenyl ether functional group contained in one molecule of the alkenyl ether compound. The composition is not hindered by oxygen from being polymerized, cures quickly even without using a special polymerizable monomer or a particular polymerization initiator, little forms an unpolymerized layer on the surface even when polymerized and cured in a highly humid environment such as in the oral cavity, and is suited as a filling/restorative material for dental use.
