Abstract
[Problem] Provided is a hardcoat-less film that is relatively lightweight, has excellent mechanical strength, and has excellent heat resistance even without regulated PFAS substance. [Solution] A hardcoat-less film that fulfills a condition that an elastic-to-plastic ratio is 70% or more in an indentation test and a glass transition temperature and a melting point each are neither lower than nor equal to 200° C., and fulfills at least one of a condition that a Young's modulus is 1000 MPa or more in an indentation test or a condition that a Young's modulus is from 1000 to 5000 MPa in a tensile test. [Selected Drawing] None
