Abstract: A resin molded product, a laminate, and a decorative sheet having high weatherability. A decorative sheet includes a resin molded product as a protective layer, and the resin molded product includes an ultraviolet absorber having pKa of −5.5 or more and −4.5 or less when irradiated with light, and a photostabilizer having pKa of 3.0 or more and 7.0 or less. The added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the resin.

Abstract: A decorative sheet includes a primary film layer; a transparent resin layer; and a surface protective layer, in this order; the surface protective layer is formed of a plurality of layers with a layer located on an outermost surface is a surface protective layer, and a layer underlying the surface protective layer is a second surface protective layer and includes one or more ionizing radiation-curable resins having an erosion rate E in a range of 0.10 μm/g or more and 0.45 μm/g or less, and one or more thermosetting resins having an erosion rate E in a range of 0.30 μm/g or more and 0.6 μm/g or less, the erosion rate E being measured by using polygonal alumina powder having an average particle size (D50) of 1.2 μm, and a mass ratio between the ionizing radiation-curable resin and the thermosetting resin (ionizing radiation-curable resin/thermosetting resin) is 95/5 to 40/60.
