PROBLEM TO BE SOLVED: To obtain a surface protecting sheet or a marking film capable of providing a molded product excellent not only in abrasion resistance and chemical resistance but also in long-term weather resistance at a low cost and not forming a crack in a curved surface part of the molded product in bonding to the surface of the molded product. SOLUTION: This surface protecting sheet has a protective layer which comprises a heat crosslinked reaction product of an active energy beam curable resin composition containing a polymer having 100-300 g/eq. (meth)acryl equivalent, 20-500 hydroxyl value and 5,000-50,000 weight average molecular weight, a polyfunctional isocyanate and an ultraviolet light absorbent which is a bisbenzotriazole-based ultraviolet light absorbent of the formula [R1 and R2 are each hydrogen atom or a 1-10C alkyl group; (n) and (n') are each an integer of 4-8; (m) and (m') are each an integer of 1-20] as active ingredients, in a surface protecting sheet in which at least a protective layer is provided on one side of a substrate sheet and at least an adhesive layer is provided on the opposite surface.
