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 L/L, wherein Lrepresents a first length of the cured product before a tensile test and Lrepresents 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.
