A protective film containing a transparent polyolefin resin layer with improved or even superior weather resistance, and a sheet using the protective film. A protective film according to the present embodiment includes at least a transparent polyolefin resin layer. The transparent polyolefin resin layer 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. (In general formula (I), R is an alkyl group having 1-18 carbon atoms, or a cycloalkyl group having 5-8 carbon atoms.)

Protective film and sheet

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 comprises at least a transparent polyolefin resin layer, wherein the transparent polyolefin resin layer contains a first hydroxyphenyltriazine-based ultraviolet absorber (UVA-A) having a structure represented by the general formula below. In the general formula, 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.

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 &#x2212;5.5 or more and &#x2212;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.

Resin molded product, laminate, and decorative sheet

The purpose is to provide an antiglare light diffusing member that can satisfy both of external light reflection preventiveness and good contrast when being used for a display. The antiglare light diffusing member is made to be an antiglare light diffusing member having an antiglare light diffusing layer including a binder matrix and particles on a transparent base material, wherein the two types of arithmetical mean roughness (Ra, Ra) of the antiglare light diffusing layer defined by JIS-B0601-1994 are in the following range: Rais in the range of 0.008-0.020 &#x3bc;m when cutoff wavelength &#x3bb;c is 0.008 mm; and Rais less than 0.200 &#x3bc;m when cutoff wavelength &#x3bb;c is 0.8 mm.

Antiglare light diffusing member and display having antiglare light diffusing member

The present invention aims to provide an antiglare light diffusing member utilizing internal diffusion and surface diffusion in combination, wherein a surface haze value mainly representing the degree of the surface diffusion and an internal haze value mainly representing the degree of the internal diffusion are easily adjusted independently from each other. An antiglare light diffusing member comprising an antiglare light diffusing layer comprising a binder matrix and a particle A and a particle B on a transparent base material, wherein the difference between the refraction index of the particle A and the refraction index of the binder matrix is less than 0.02, and the difference between the refraction index of the particle B and the refraction index of the binder matrix is in the range of 0.03-0.20.
