摘要： To provide a decorative sheet including a transparent resin layer having high transparency and excellent surface scratch resistance from the viewpoint of the design properties and a transparent resin sheet. A decorative sheet (1) according to one aspect of the present invention has a transparent resin layer (4) containing a crystalline polypropylene resin as the main component, in which a value of a peak area ratio x represented by the following expression (1) of the transparent resin layer (4) is x ≥ 0.4. Herein, S040, S130, and Sam in the following expression (1) are peak areas determined from an X-ray diffraction spectrum obtained by measuring the transparent resin layer with an X-ray diffractometer, S040 is the peak area from the Miller index (040) of polypropylene α crystals, S130 is the peak area from the Miller index (130) of the polypropylene α crystals, and Sam is the peak area of an amorphous material. Peak area ratio x = S 040 + S 130 Sam

摘要： Provided are a decorative sheet that has a transparent resin layer having good V groove bending processability (post-processability) while maintaining high scratch resistance and transparency and a method of producing the decorative sheet. A decorative sheet (1) according to the present embodiment is a decorative sheet including at least a transparent resin layer (3) containing a highly crystalline polypropylene resin as a main component. The transparent resin layer (3) contains a low crystalline polypropylene resin added thereto in the range of 0.1 part by mass or more and 20 parts by mass or less relative to 100 parts by mass of the highly crystalline polypropylene resin, the low crystalline polypropylene resin having a tensile modulus in the range of 25 MPa or more and 500 MPa or less.

摘要： To provide a decorative sheet including a transparent resin layer having excellent post-processing resistance and high transparency. A decorative sheet (1) according to one aspect of the present invention has a transparent resin layer (4) containing a crystalline polypropylene resin as the main component. A value of a peak intensity ratio x represented by the following expression (1) of the transparent resin layer (4) is x ≤ 0.65. Herein, 1997, 1938, and 1973 in the following expression (1) are peak intensity values calculated from the absorption spectrum obtained by Fourier infrared spectrometry of the transparent resin layer, and 1997 is the peak intensity value at a wavenumber of 997cm -1 , 1938 is the peak intensity value at a wavenumber of 938cm -1 , and 1973 is the peak intensity value at a wavenumber of 973cm -1 . Peak intensity ratio x = I 997 − I 938 I 973 − I 938
