Abstract
The present invention provides a layered body having high hardness and excellent flexibility and useful as a substitute material for glass, and the layered body includes a substrate film, a hard coat layer on one face of the substrate film, and a resin-cured layer on the other face of the substrate film. The layered body is not cracked when wound on a 30 mm-diameter cylinder and has a hardness of 0.5 to 1.5 GPa when an indenter is pushed in 500 nm by a nano-indentation method and/or a hardness of 0.29 to 1.10 GPa at 500 mN load using a micro-hardness tester.
