Abstract
A resin for thermal imprint include a cyclic-olefin-based thermoplastic resin that contains at least one of skeletons represented by the following chemical equation 1 or the following chemical equation 2 in a main chain. The glass transition temperature Tg (° C.) and the value ([M]) of MFR at 260° C. satisfy the following equation 1, and [M]>10. The thermal imprint characteristics (transferability, mold release characteristic, and the like) are superior and the productivity (throughput) is improved.Tg(° C.)<219×log [M]−104 [Equation 1]
