no. 1 Embodiment approach

[0036]

[0037] The decorative sheet of the present embodiment is a decorative sheet having a transparent resin layer mainly composed of a crystalline polypropylene resin. In this embodiment, the case where the transparent resin layer is comprised by the transparent resin sheet was shown as an example. The transparent resin layer can also be formed by coating.

[0038] "Mainly composed of crystalline polypropylene resin" means, for example, that 80% by mass to 100% by mass, preferably 90% by mass to 100% by mass of the resin constituting the transparent resin layer is a crystalline polypropylene resin. .

[0039] Prepare the transparent resin layer as a transparent resin sheet, or prepare a transparent resin sheet made of the same composition as the transparent resin layer, and carry out X-ray diffraction measurement on the transparent resin sheet by an X-ray diffraction device to obtain an X-ray diffraction spectrum. In the X-ray diffraction spectrum, it is important that...

Embodiment 1-1 to 1-6、 comparative example 1-1、1-2

[0112] In Examples 1-1 to 1-6 and Comparative Examples 1-1 and 1-2 for comparison, for the hindered phenolic antioxidant (Irganox 1010, BASF Company), 2000PPM benzotriazole UV absorber (Tinuvin 328, BASF), 2000PPM hindered amine light stabilizer (Chimassorb944, BASF) and 1000PPM phosphate metal salt nucleating agent ( The resin composition of ADK STAB NA-21, manufactured by ADEKA Corporation), was subjected to the above-mentioned film forming process using a melt extruder. In this way, transparent resin sheets 4 each having a thickness of 100 μm to be used as transparent resin layers 4 were formed into films.

[0113] At this time, each of Examples 1-1 to 1-6 and Comparative Examples 1-1 and 1-2 was prepared by controlling the peak area ratio x. Table 1 shows the peak area ratio x of the transparent resin sheets produced in Examples 1-1 to 1-6 and Comparative Examples 1-1 and 1-2.

[0114] The X-ray diffraction spectrometry was measured by a parallel method using an X-ray di...

Embodiment 1-7 to 1-11

[0116] In Examples 1-7 to 1-11, 500PPM of hindered phenolic antioxidants (Irganox 1010, manufactured by BASF Corporation), 2000PPM of benzotriazole-based ultraviolet absorbers were added to the highly crystalline homopolypropylene resin (Tinuvin328, manufactured by BASF Corporation), 2000PPM hindered amine light stabilizer (Chimassorb 944, manufactured by BASF Corporation) and 1000PPM resin composition of nucleating agent vesicles, using a melt extruder to perform the above-mentioned film-forming process. In this way, transparent resin sheets 4 each having a thickness of 100 μm to be used as transparent resin layers 4 were formed into films. Table 1 shows the peak area ratio x of each transparent resin sheet 4 obtained.

[0117] It should be noted that the added nucleating agent vesicles were obtained in the following manner: 100 parts by mass of methanol, 82 parts by mass of a phosphate metal salt-based nucleating agent (ADK STAB NA-21, manufactured by ADEKA Corporation), 5 ...

Abstract

Provided are: a cosmetic sheet having a transparent resin layer with excellent transparency and surface scratch resistance in terms of design properties; and a transparent resin sheet. A cosmetic sheet (1) according to an embodiment of the present invention comprises a transparent resin layer (4) in which a crystalline polypropylene resin is the main component. The value of the peak area ratio x,which is represented by formula (1), of the transparent resin layer (4) is x>=0.4. In formula (1), S040, S130 and Sam are peak areas obtained from an X-ray diffraction spectrum acquired by using an X-ray diffractometer to measure the transparent resin layer, and S040 is the peak area from the Miller index (040) of polypropylene alpha crystals, S130 is the peak area from the Miller index (130) of polypropylene alpha crystals, and Sam is the peak area of amorphous material.

Description

technical field [0001] The present invention relates to a decorative sheet and a transparent resin sheet. Background technique [0002] There are, for example, technologies described in Patent Documents 1 to 6 as technologies related to decorative sheets using olefin-based resins that are attracting attention as decorative sheets replacing polyvinyl chloride decorative sheets. [0003] However, among these decorative sheets, there is a problem that few decorative sheets include a transparent resin layer having high transparency from the viewpoint of design and excellent surface damage resistance.
