摘要

PROBLEM TO BE SOLVED: To provide an active energy ray-curable composition having excellent curability, abrasion resistance, adhesion and ejection property. An acrylamide compound (A1) having an ester structure having a molecular weight of 150 or more and 250 or less, a bifunctional or higher polymerizable compound (A2), an initiator (B1) having a maximum absorption wavelength of 350 nm or less, and the above. An active energy ray-curable composition containing an ultraviolet absorber (C1) having a maximum absorption wavelength such that the difference from the maximum absorption wavelength of the initiator (B1) is 40 nm or more.
