Abstract
Active-energy-ray-curable composition including: monofunctional monomers; and polymerization initiator, cured material of the composition satisfying 0.30≦D≦0.85, where D is difference between peak-area-ratios A and B in infrared-ATR and obtained by: the composition is coated on polycarbonate substrate to form coated film having average thickness of 10 μm; the film is irradiated with active energy rays having light quantity of 500 mJ/cmat UV intensity of 1.0 W/cmfor curing; the A is obtained from Formula (1) by infrared-ATR at one portion present from the cured material surface through 1 μm away therefrom toward the substrate, the B is obtained from Formula (1) by infrared-ATR at one portion present from the substrate-cured material interface through 1 μm away therefrom toward the cured material surface,Peak-area (from 1,679 mthrough 1,751 m/peak-area (from 1,096 mthrough 1,130 m)  Formula (1), andthe A and B obtained are used to obtain D from Formula (2):=peak-area-ratio−peak-area-ratio  Formula (2).
