Abstract

An active energy ray curable composition including a polymerizable compound is provided. When a three-layer cured product of the active energy ray composition is obtained by a specific procedure, the three-layer cured product has (1) a stretchability of 1.1 or more and (2) a glass transition temperature of 50° C. or more. The stretchability is defined by a ratio L2/L1, wherein L1 represents a first length of the cured product before a tensile test and L2 represents a second length of the cured product after the tensile test. The tensile test includes stretching the cured product along with the substrate with a tensile tester at a stretching speed of 20 mm/min and a temperature of 180° C.

1 . An active energy ray curable composition, comprising:
 a polymerizable compound comprising 50% to 90% by mass of a monofunctional reactive compound having a cyclic structure,   wherein, when a three-layer cured product of the active energy ray composition is obtained by:   forming a first film of the active energy ray curable composition having an average thickness of 10 μm on a polycarbonate substrate having a thickness of 100 μm and irradiating the first film with an active energy ray having a light quantity of 1,500 mJ/cm 2 ;   forming a second film of the active energy ray curable composition having an average thickness of 10 μm on the first film and irradiating the second film with an active energy ray having a light quantity of 1,500 mJ/cm 2 ; and   forming a third film of the active energy ray curable composition having an average thickness of 10 μm on the second film and irradiating the third film with an active energy ray having a light quantity of 1,500 mJ/cm 2 ,   the three-layer cured product has:
