Abstract: The present invention is to provide a monomer mixture that is cured rapidly even in the presence of oxygen and that forms a cured product having high hardness and excellent adhesion to metals and/or glass. The monomer mixture according to an embodiment of the present invention contains two or more types of cationically polymerizable monomers. As the cationically polymerizable monomers, the monomer mixture contains at least 10 wt. %, based on a total amount of the monomer mixture, of a compound having at least one cationically polymerizable group selected from the group consisting of a vinyl ether group, an epoxy group, and an oxetanyl group, and at least one hydroxy group in a molecule, and at least 5 wt. %, based on the total amount of the monomer mixture, of a compound represented by Formula (b). In the formula, R represents an s-valent straight-chain or branched saturated aliphatic hydrocarbon group or an s-valent group having two or more straight-chain or branched saturated aliphatic hydrocarbon groups bonded to each other through an ether bond, and s represents an integer of 2 or greater.

Abstract: Provided is a sheet-shaped mold possessing a high strength and having a low breakage rate in demolding even in a case where the mold is thin and has a large-area. The sheet-shaped mold is prepared by combining a cured silicone rubber containing a polyorganosiloxane and a fiber for reinforcing the cured silicone rubber. The fiber may comprise a cellulose nanofiber. The sheet-shaped mold may have an uneven pattern on at least one surface (or side) thereof. The fiber may be surface-treated with a hydrophobizing agent. The fiber may forma nonwoven fabric, and the nonwoven fabric may be impregnated with the cured silicone rubber. The cured silicone rubber may comprise a two-component curable silicone rubber having a polydimethylsiloxane unit. The sheet-shaped mold may be a mold for nanoimprint lithography using a photo-curable resin.

Abstract translation: 即使在模具薄且面积大的情况下，也提供了具有高强度且脱模时断裂率低的片状模具。 通过将含有聚有机硅氧烷的固化硅橡胶和用于增强固化的硅橡胶的纤维组合而制备片状模具。 纤维可以包含纤维素纳米纤维。 片状模具可以在其至少一个表面（或侧面）上具有不均匀的图案。 纤维可以用疏水化剂进行表面处理。 纤维可以形成非织造织物，并且非织造织物可以用固化的硅橡胶浸渍。 固化的硅橡胶可以包含具有聚二甲基硅氧烷单元的双组分可固化的硅橡胶。 片状模具可以是使用光固化树脂的纳米压印光刻的模具。
