Patent ID: 8721950

Claim:
A thermal imprint method comprising: pressing a mold, which is heated to a temperature less than or equal to a glass transition temperature Tg (° C.) of a resin for thermal imprint +45° C., against an injection molded body having a thickness of greater than or equal to 1 mm and comprising the resin for thermal imprint, thereby transferring a micrometer or nanometer-scale pattern of the mold, wherein the resin for thermal imprint comprises: a cyclic-olefin-based thermoplastic resin that contains at least one skeleton, represented by a chemical equation 2, in a main chain, wherein a glass transition temperature Tg (° C.) of the resin and a value [M] of MFR at 260° C. satisfy an equation 1; and [M]>20; wherein the chemical equation 2 is represented by: and the equation 1 is: Tg (° C.)<219×log [ M]− 104; and further, wherein R 20 to R29 in chemical equation 2 may differ or may be same, each of which is a substituent containing a hydrogen atom, a deuterium atom, a hydrocarbon radical having a carbon number of 1 to 15, a halogen atom, or a hetero atom of oxygen or sulfur, and may form a monocyclic or polycyclic structure with one another; and, wherein [M] in equation 1 represents a value of MFR at 260° C.
