  An object of the present invention is to provide a paste-type cement composition which while retaining adhesion to tooth substance, biocompatibility, surface curability and fluorine sustained-releasability which are the characteristics derived from the conventional glass ionomer cement, reduces water sensitivity which is shortcoming of the conventional glass ionomer cement, enables simple mixing operation, does not adversely affect on the various properties of a cured cement depending on a difference in operators or a skill degree, and can afford various stable properties. There is provided a two paste-type glass ionomer cement comprising a resin-based paste containing a hydrophobic polymerizable monomer and a polymer of acidic group-containing polymerizable monomers which are insoluble to each other, and a water-based paste containing a hydrophilic polymerizable monomer and water which are soluble to each other, in which an acid reactive filler is contained in at least one of pastes.

  本发明的一个目的是提供一种浆糊型水泥组合物，该组合物在保持对牙齿物质的粘附性、生物相容性、表面可固化性和氟释放性这些传统玻璃离子水泥的特性的同时，减少了传统玻璃离子水泥的水敏感性这一缺点，实现了简单的混合操作，不会对已固化水泥的各种性质产生不利影响，不会受到操作者差异或技能水平的影响，并且可以提供各种稳定的性质。提供了一种双浆糊型玻璃离子水泥，包括一种含有疏水性可聚合单体和含有酸性基团可聚合单体聚合物的树脂基浆糊，这些单体在彼此之间不溶解，以及一种含有亲水性可聚合单体和水的水基浆糊，这些单体在彼此之间可溶解，其中至少有一个浆糊中含有酸反应填料。

  Provided is a sulfonium salt manufacturing method which can reduce the production of a monosulfonium salt. A method of manufacturing a sulfonium salt includes preparing a first sulfonium salt containing a sulfonium cation and a first anion, preparing a second sulfonium salt by exchanging the first anion for a halide ion, and preparing a third sulfonium salt by exchanging the halide ion for a second anion.

  Articles and methods for increasing the triplet upconversion threshold, e.g, by utilizing a heavy atom- functionalized triplet exciton upconverter, are generally described. Some embodiments, for example, are directed to articles and methods that use a triplet sensitizer and a heavy atom- functionalized upconverter to produce upconverted photons (e.g., light of a second energy). The light may be used to polymerize a polymerizable species. Other upconversion configurations can also be used in other embodiments. In some cases, this may allow true 3D printing to be achieved due to improved control of light absorption, e.g., without needing to "print" on a layer- by-layer basis.

  本文通常描述了增加三重态上转换阈值的方法和文章，例如利用重原子功能化的三重态激子上转换器。例如，某些实施例涉及使用三重态敏化剂和重原子功能化的上转换器来产生上转换光子（例如，第二种能量的光）。该光可以用于聚合可聚合物种。其他上转换配置也可以在其他实施例中使用。在某些情况下，这可能允许实现真正的3D打印，因为可以更好地控制光吸收，例如，无需按层进行“打印”。
