摘要： A resin molded product, a laminate, and a decorative sheet having high weatherability are provided. A decorative sheet (1) includes a resin molded product as a protective layer (3), 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 molded product.

摘要： Provided are a protective film containing a transparent polyolefin resin layer with superior weather resistance, and a sheet using the protective film. A protective film (10) according to the present embodiment includes at least a transparent polyolefin resin layer (11). The transparent polyolefin resin layer (11) contains a hindered amine light stabilizer represented by general formula (I) below in a range of 0.05 parts by mass or more and 5 parts by mass or less with respect to 100 parts by mass of a transparent olefin resin included in the transparent polyolefin resin layer (11). (In general formula (I), R is an alkyl group having 1-18 carbon atoms, or a cycloalkyl group having 5-8 carbon atoms.)

摘要： Provided are: a protective film that includes at least one of a transparent polyolefin resin layer and a surface protection layer, and that has excellent weather resistance and a low level of white turbidity, which is a factor that impairs design properties; and a sheet using the protective film. The protective film (10) according to a present embodiment comprises at least a transparent polyolefin resin layer (11), wherein the transparent polyolefin resin layer (11) contains a first hydroxyphenyltriazine-based ultraviolet absorber (UVA-A) having a structure represented by general formula (1) below. In general formula (1), R1-R3 each independently represent a hydrogen atom, a methyl group, a phenyl group, or an alkoxy group, and at least two of R1-R3 are an alkoxy group having 8-18 carbon atoms, R4 and R5 each independently represent a hydroxyl group, a methyl group, or a hydrogen atom, and R6-R8 each independently represent a methyl group or a hydrogen atom.
