Claim Text:
1. A curable composition for nanoimprinting, comprising two or more polymerizable monomers, wherein the two or more polymerizable monomers includes 90 percent by weight or more of two or more monofunctional radically polymerizable monomers, the two or more monofunctional radically polymerizable monomers give a polymer having a glass transition temperature of 25° C. or higher, the two or more monofunctional radically polymerizable monomers are at least two compounds selected from the group consisting of (meth)acrylic ester compounds, styrenic compounds, and vinyl ether compounds, the two or more monofunctional radically polymerizable monomers include at least one radically polymerizable monomer intramolecularly having a cyclic structure as the monofunctional radically polymerizable monomers, the at least on radically polymerizable monomer intramolecularly having a cyclic structure is at least one compound selected from the group consisting of compounds represented by following Formulae (1) to (3): wherein R the at least one radically polymerizable monomer intramolecularly having a cyclic structure occupies 40 percent by weight or more of the total weight of the polymerizable monomers in the curable composition, with the proviso that the at least on radically polymerizable monomer intramolecularly having a cyclic structure includes a compound represented by Formula (1), the compound represented by Formula (1) occupies 40 percent by weight or more of the total weight of the polymerizable monomers, and at least one of the following conditions A, B, and C is met: [A] the total weight of the compound represented by Formula (1) and the compound represented by Formula (3) occupies 90 percent by weight or more of the total weight of the polymerizable monomers; [B] the total weight of the compound represented by Formula (1) and (meth)acrylic acid alkyl esters whose alkyl moiety has 1 to 10 carbon atoms occupies 90 percent by weight or more of the total weight of the polymerizable monomers; [C] the total weight of the compound represented by Formula (1) and/or (3) and phenolic-hydroxyl-containing monofunctional radically polymerizable monomers and/or caboxyl-containing monofunctional radically polymerizable monomers occupies 90 percent by weight or more of the total weight of the polymerizable monomers, and the total weight of the phenolic- hydroxyl-containing monofunctional radically polymerizable monomers and the carboxyl-containing monofunctional radically polymerizable monomers occupies 10 percent by weight or more of the total weight of the polymerizable monomers.
