Patent ID: 8324332

Claim:
A resin for thermal imprint and for producing an injection molded body, the resin comprising a cyclic-olefin-based thermoplastic resin that contains at least one of skeletons represented by a following chemical equation 4 in a main chain, and wherein: a glass transition temperature Tg (° C.) of the resin and a value ([M]) of MFR at 260° C. satisfy a following equation 1; and [M]>20 and Tg>90° C. Tg (° C.)<219×log [ M ]−104 [Equation 1] (R20 to R29 in chemical equation 4 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, and a hetero atom of oxygen, or sulfur, and may form a monocyclic or polycyclic structure with one another; and [M] in equation 1 represents a value of MFR at 260° C.).
