An object of the present invention is to provide a urethane (meth) acrylate, an active energy ray-curable resin composition, a cured product, and a protective film.n n n The present invention provides a urethane (meth) acrylate, which is obtained by reacting a monomer group. The monomer group includes a saturated aliphatic polyisocyanate, a saturated aliphatic polyol, a polyether polyol, and / Or polyester polyol and hydroxyl-containing (meth) acrylic acid ester, with respect to 100 parts by mass of the monomer group, containing 0.2 to 10 parts by mass of the polyether polyol and / or the polyester polyol with respect to 100 parts by mass of urethane (meth) acrylate, containing 19 to 48 parts by mass of cycloalkylene. |
