摘要： 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.

摘要： Provided is an information recording object designed such that a read angle of embedded information is easily assessed. An information recording object, which comprises a combined image including an image C1 and an image C2 formed on the image C1, is configured so that the image C1 and the image C2 are different patterns generated according to specific rules and so that the reflected light quantities differ due to respective viewing angles, and the image C1 and/or the image C2 can be recognized in the combined image in accordance with the viewing angle, and the combined image has an angle-specifying area formed using a material having the same reflected light quantity as the image C2.
