Actinic-ray-curable composition for floor material

The purpose of the present invention is to provide an actinic-ray-curable composition for floor materials which retains conventional physical performance and which, despite this, shows sufficient curability when irradiated with actinic rays by a UV-LED light source having a peak wavelength of 350-420 nm, to have durable physical properties. The actinic-ray-curable composition for floor materials comprises an actinic-ray-polymerizable compound (A) having an ethylenic double bond and an acylphosphine oxide photopolymerization initiator (B).
