Description

[Technical field]

[0001] The present invention relates to a decorative sheet and a decorative material. [Background technology]

[0002] Conventionally, there are decorative sheets used for surface decoration of interior materials and fittings for buildings such as houses, building materials such as fittings, furniture and fixtures, housing equipment, home appliances, etc., and decorative materials in which a wooden base material or the like is attached to a decorative sheet. Any design can be imparted to such decorative sheets and decorative materials by printing a pattern.

[0003] Decorative sheets and decorative materials having patterns are required to have improved scratch resistance because there is a risk that if the surface is scratched during transportation or processing, part of the pattern will be lost and the design will be reduced. For example, there is a decorative sheet in which a resin film is bonded to the surface of a substrate having a pattern in order to protect the surface of the decorative sheet and improve its scratch resistance (for example, Patent Document 1).

[0004] In addition, decorative sheets having such a resin film (protective film) that protects the surface are protected by the protective film during transportation and processing, when there is a risk of the surface being scratched, and when used after transportation or processing, the protective film is often peeled off. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-203493 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, protective films that are removable from the decorative sheet during use have high releasability, and therefore tend to have weak adhesion between the decorative sheet and the protective film. Here, releasability refers to the ease with which the protective film can be peeled off from the decorative sheet.

[0007] Therefore, when multiple decorative sheets are transported, if force is applied in the parallel direction (plate surface direction) in a state where the protective film surfaces of the decorative sheets are overlapped, there is a risk that the protective film will peel off from the decorative sheet. In addition, there is a risk that the protective film will naturally peel off from the decorative sheet due to its weak adhesion.

[0008] On the other hand, when a protective film with strong adhesion is used, there is a risk that when the protective film is peeled off from the decorative sheet, the layer of the decorative sheet on the protective film side (for example, the topcoat layer) will peel off at the same time as the protective film.

[0009] In view of the above circumstances, an object of the present invention is to provide a decorative sheet and a decorative material that are provided with a protective film that is not easily peeled off during transportation. [Means for solving the problem]

[0010] In order to solve the above problems, the present invention proposes the following means. The decorative sheet of the present invention is a decorative sheet comprising a colored base fabric layer, a pattern printed layer provided on the upper side of the colored base fabric layer, a top coat layer provided on the upper side of the pattern printed layer, and a protective film provided on the upper side of the top coat layer, and when the protective films of two of the decorative sheets are stacked facing each other in the thickness direction, the static friction coefficient between the opposing protective films is 0.5 or less.

[0011] In the decorative sheet, the protective film may include a protective layer and a release layer provided on the upper side of the protective layer.

[0012] In the decorative sheet, the surface of the protective film may be provided with an uneven shape.

[0013] The decorative sheet may further include a transparent thermoplastic resin layer provided on the upper side of the pattern printed layer, and a primer layer provided on the lower side of the colored base fabric layer.

[0014] In the decorative sheet, the adhesion between the top coat layer and the protective film may be 0.14 N / inch or more.

[0015] In the decorative sheet, the adhesion between the top coat layer and the protective film may be 0.7 N / inch or less.

[0016] The decorative material of the present invention comprises any of the decorative sheets described above and a substrate provided below the decorative sheet. Effect of the Invention

[0017] According to the decorative sheet and decorative material of the present invention, it is possible to provide a decorative sheet and decorative material that are provided with a protective film that is not easily peeled off during transportation. [Brief description of the drawings]

[Diagram 2] FIG. 1 is a cross-sectional view showing a schematic diagram of a decorative material according to an embodiment of the present invention. [Diagram 3] FIG. 2 is a cross-sectional view showing a schematic diagram of the decorative material in which protective films are stacked on top of each other. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] An embodiment of the present invention will be described with reference to the drawings.

[0020] FIG. 1 is a cross-sectional view that shows a schematic diagram of a decorative sheet 100 according to this embodiment. 1, the thickness direction of the decorative sheet 100 is defined as the "vertical direction V," the side of the decorative sheet 100 on which the protective film 20 is provided is defined as the "upper side UP" in the vertical direction V, and the side opposite the upper side UP is defined as the "lower side LO" in the vertical direction V. In addition, the plate surface direction of the decorative sheet 100 is defined as the "width direction C."

[0021] FIG. 2 is a cross-sectional view that illustrates a decorative material 200 according to this embodiment. The decorative material 200 comprises a decorative sheet 100 and a substrate 30 .

[0022] The substrate 30 is a layer provided on the lower side LO of the decorative sheet 100. Particle board, medium density fiberboard (MDF), or the like can be used as the substrate 30. Alternatively, the substrate 30 may be a metal plate-like member such as aluminum or stainless steel, or a composite plate in which a metal such as aluminum is attached to both sides of a core material made of resin such as polyethylene.

[0023] The decorative sheet 100 comprises a decorative sheet body 10 and a protective film 20. Here, the protective film 20 is provided for the purpose of protecting the surface (upper UP surface) of the decorative sheet main body 10, and is a layer that can be peeled off and removed when using the decorative sheet main body 10. In other words, the protective film 20 is a protective film that prevents the decorative sheet main body 10 before use from being damaged during transportation, processing, etc., and can be peeled off and removed from the decorative sheet main body 10 when using the decorative sheet main body 10.

[0024] The decorative sheet body 10 comprises a colored base fabric layer 1, a primer layer 2, a pattern printed layer 3, a transparent thermoplastic resin layer 4, and a top coat layer 5.

[0025] The colored raw fabric layer 1 is a sheet-like layer made of a known material on which printing can be performed. A resin sheet such as polyethylene, polypropylene, or polyvinyl chloride can be used as the colored raw fabric layer 1. A fibrous sheet such as tissue paper or titanium paper can also be used as the colored raw fabric layer 1.

[0026] The primer layer 2 is a layer provided on the lower side LO of the colored raw fabric layer 1. As the primer layer 2, a polyester resin, a urethane resin, an acrylic resin, or the like can be used. As a method for laminating the primer layer 2, a known printing method such as gravure printing, offset printing, flexographic printing, silk screen printing, or inkjet printing, or a forming method using a known coating device can be used. The primer layer 2 may also be formed by a melt extrusion molding method.

[0027] The primer layer 2 is a layer provided for the purpose of improving the adhesion between the decorative sheet 100 and the substrate 30. If sufficient adhesion is already present between the decorative sheet 100 and the substrate 30 without providing the primer layer 2, the decorative sheet 100 does not need to be provided with the primer layer 2.

[0028] The pattern-printed layer 3 is a layer provided on the upper side UP of the colored raw fabric layer 1. The pattern-printed layer 3 is formed by printing a pattern such as wood grain, stone grain, or sand grain on the upper side UP of the colored raw fabric layer 1. The printing method for the pattern-printed layer 3 can be a known printing method such as gravure printing, offset printing, flexographic printing, silk screen printing, or inkjet printing. For the pattern-printed layer 3, a known printing ink suitable for the printing method to be adopted can be used.

[0029] The transparent thermoplastic resin layer 4 is a layer provided on the upper side UP of the pattern-printed layer 3. Polypropylene resin or the like can be used as the transparent thermoplastic resin layer 4. It is preferable to use a transparent or semi-transparent material for the transparent thermoplastic resin layer 4 so that the pattern of the pattern-printed layer 3 can be seen through it.

[0030] The transparent thermoplastic resin layer 4 may be formed by a known printing method such as gravure printing, offset printing, flexographic printing, silk screen printing, or inkjet printing, or a forming method using a known coating device. The transparent thermoplastic resin layer 4 may also be formed by a melt extrusion molding method.

[0031] Furthermore, an uneven shape may be formed by embossing on the surface of the upper side UP of the transparent thermoplastic resin layer 4. By embossing the transparent thermoplastic resin layer 4, it is possible to impart a design in the form of any uneven shape to the decorative sheet body 10.

[0032] The topcoat layer 5 is a layer provided on the upper side UP of the transparent thermoplastic resin layer 4. For the topcoat layer 5, a thermosetting resin such as an acrylic urethane resin, an ionizing radiation curable resin, an ultraviolet curable resin, or a mixture thereof can be used. For the topcoat layer 5, it is preferable to use a transparent or semi-transparent material that allows the pattern of the pattern-printed layer 3 to be seen through the transparent thermoplastic resin layer 4.

[0033] It is desirable to use a material for the top coat layer 5 that can impart stain resistance to the decorative sheet body 10. If the top coat layer 5 has stain resistance, when stains from food, drink, etc. adhere to the surface of the decorative sheet body 10, the stains can be easily wiped off.

[0034] In addition, a protective film 20 is attached to the upper side UP of the topcoat layer 5. Therefore, in order to prevent the topcoat layer 5 from peeling off together with the protective film 20 when the protective film 20 is peeled off from the decorative sheet main body 10, it is desirable to use a material with high releasability for the topcoat layer 5. Here, releasability refers to the ease with which the protective film 20 can be peeled off from the decorative sheet main body 10.

[0035] A known printing method such as gravure printing, offset printing, flexographic printing, silk screen printing, or inkjet printing can be used as a method for laminating the topcoat layer 5. The topcoat layer 5 may also be laminated using a known coating device.

[0036] The protective film 20 includes an adhesive layer 6, a protective layer 7, and a release layer 8. The protective film 20 is a layer provided on the upper side UP of the decorative sheet main body 10. That is, in the decorative sheet 100, the protective film 20 is a layer provided on the upper side UP of the top coat layer 5.

[0037] The adhesive layer 6 is a layer provided on the upper side UP of the top coat layer 5. The adhesive layer 6 is a layer provided on the lower side LO of the protective film 20, and is a layer for adhering the protective film 20 to the decorative sheet body 10.

[0038] The material used for the adhesive layer 6 is not particularly limited as long as it can adhere the protective film 20 to the decorative sheet main body 10, and for example, a known pressure-sensitive adhesive or heat-sensitive adhesive can be used. For example, an acrylic resin can be used for the adhesive layer 6. It is desirable to use a transparent or semi-transparent material for the adhesive layer 6 so that the pattern of the pattern-printed layer 3 can be seen through the transparent thermoplastic resin layer 4 and the top coat layer 5.

[0039] The protective film 20 is attached to the surface of the decorative sheet main body 10 by the adhesive force (adhesion) of the adhesive layer 6. Therefore, when the decorative sheet 100 is manufactured, the adhesive layer 6 is not laminated by itself onto the upper side UP of the topcoat layer 5, but is laminated onto the upper side UP of the topcoat layer 5 by laminating the adhesive layer 6, the protective layer 7, and the release layer 8 to manufacture the protective film 20, and attaching it to the surface of the upper side UP of the decorative sheet 100.

[0040] The protective layer 7 is a layer provided on the upper side UP of the adhesive layer 6. The protective layer 7 is a layer in the decorative sheet 100 for protecting the decorative sheet main body 10 from scratches and the like. There are no particular limitations on the material used for the protective layer 7 as long as it can protect the decorative sheet main body 10, and for example, a polyolefin thermoplastic resin such as polyethylene can be used. It is desirable to use a transparent or semi-transparent material for the protective layer 7 that allows the pattern of the pattern-printed layer 3 to be seen through the transparent thermoplastic resin layer 4, the top coat layer 5, and the adhesive layer 6.

[0041] The release layer 8 is a layer provided on the upper side UP of the protective layer 7 . Here, the protective film 20 is often wound around a cylindrical roll during production and storage. During production of the protective film 20, for example, the adhesive layer 6, the protective layer 7, and the release layer 8 are laminated to form the protective film 20, and then the protective film 20 is wound around a roll so as to overlap in the thickness direction.

[0042] When the protective film 20 is laminated to the decorative sheet main body 10, the protective film 20 is pulled out from a roll and cut to a desired size (length). The protective film 20 cut to the desired size is laminated to the decorative sheet main body 10 to form the decorative sheet 100.

[0043] In the protective film 20 wound around a roll, the adhesive layer 6 and the release layer 8 are wound so as to overlap in the thickness direction. In order to prevent the overlapping adhesive layer 6 and release layer 8 from adhering due to the adhesive force of the adhesive layer 6, it is desirable for the release layer 8 to have releasability (peelability). By having the release layer 8 have releasability, the overlapping adhesive layer 6 and release layer 8 are easily peeled off when the protective film 20 is pulled out from the roll, and the protective film 20 can be easily pulled out.

[0044] The material used for the release layer 8 is not particularly limited as long as it can impart releasability to the release layer 8, and for example, a long-chain alkyl pentane polymer resin can be used. For the release layer 8, it is desirable to use a transparent or semi-transparent material that allows the pattern of the pattern-printed layer 3 to be seen through the transparent thermoplastic resin layer 4, the top coat layer 5, the adhesive layer 6, and the protective layer 7.

[0045] When the protective films 20 of two decorative sheets 100 are stacked facing each other in the thickness direction, the static friction coefficient between the facing protective films 20 is 0.5 or less. It is more preferable that the static friction coefficient between the facing protective films 20 is 0.4 or less.

[0046] Fig. 3 is a cross-sectional view that shows, in schematic form, decorative material 200A and decorative material 200B in which protective films 20 are stacked facing each other in the thickness direction. In Fig. 3, a surface 20s of protective film 20 included in decorative material 200A and a surface 20s of protective film 20 included in decorative material 200B are stacked facing each other in the thickness direction.

[0047] Here, the surface 20s of the protective film 20 is the surface of the upper side UP of the protective film 20 in Figures 1 and 2. Moreover, the thickness direction is the up-down direction V in Figures 1 and 2.

[0048] By setting the static friction coefficient between protective films 20 overlapping and facing each other in the thickness direction to 0.5 or less, in decorative materials 200A and 200B shown in Fig. 3, when a force is applied to decorative material 200B in a direction F parallel to decorative material 200B and decorative material 200B is moved in the direction F parallel to decorative material 200A, protective films 20 of decorative materials 200A and 200B will not peel off from decorative sheet body 10. Here, the parallel direction F is a direction that coincides with the width direction C.

[0049] If the coefficient of static friction between protective films overlapping each other in the thickness direction is greater than 0.5, the frictional force generated between the overlapping protective films will cause the protective films to peel off from the main body of the decorative sheet. Therefore, when the decorative sheets or decorative materials are stacked and transported, the protective films may peel off from the main body of the decorative sheet, and the surface of the main body of the decorative sheet may not be protected by the protective films. As a result, the surface of the main body of the decorative sheet may be scratched, and the design may be deteriorated.

[0050] By setting the static friction coefficient between the protective films 20 overlapping and facing each other in the thickness direction to 0.5 or less, the protective films 20 are prevented from peeling off from the decorative sheet body 10 when the decorative sheets 100 or the decorative materials 200 are stacked and transported, and the protective films 20 can protect the surface of the decorative sheet body 10. As a result, the surface of the decorative sheet body 10 is prevented from being scratched, and deterioration of the design can be suppressed. In addition, deterioration of the stain resistance caused by scratches on the topcoat layer 5 can be suppressed.

[0051] As a method for making the static friction coefficient between the protective films 20 overlapping each other facing each other in the thickness direction 0.5 or less, a material that makes the static friction coefficient between the protective films 20 0.5 or less may be used for the release layer 8. In addition, the static friction coefficient between the protective films 20 may be made 0.5 or less by providing an uneven shape on the surface 20s of the protective film 20. For example, the uneven shape can be provided by embossing the surface 20s of the protective film 20.

[0052] In addition, the adhesion between the decorative sheet main body 10 and the protective film 20 is desirably 0.14 N / inch or more. In other words, the adhesion between the topcoat layer 5 and the protective film 20 is desirably 0.14 N / inch or more. By making the adhesion between the topcoat layer 5 and the protective film 20 0.14 N / inch or more, the protective film 20 can have sufficient adhesion to the decorative sheet main body 10, and the protective film 20 can be prevented from naturally peeling off from the decorative sheet main body 10. Here, natural peeling refers to the protective film 20 peeling off from the decorative sheet main body 10 over time.

[0053] In addition, the adhesion between the decorative sheet main body 10 and the protective film 20 is desirably 0.7 N / inch or less. In other words, the adhesion between the topcoat layer 5 and the protective film 20 is desirably 0.7 N / inch or less. By making the adhesion between the topcoat layer 5 and the protective film 20 0.7 N / inch or less, it is possible to prevent the topcoat layer 5 from peeling off at the same time as the protective film 20 when the protective film 20 is peeled off from the decorative sheet main body 10 during use of the decorative sheet main body 10, and it is possible to suppress a decrease in the design and stain resistance of the decorative sheet main body 10 due to peeling of the topcoat layer 5.

[0054] The decorative sheet 100 and decorative material 200 of this embodiment comprise a colored base fabric layer 1, a pattern printed layer 3, and a top coat layer 5 in this order from the lower side LO, and further comprise a protective film 20 on the upper side UP of the top coat layer 5. Furthermore, when the protective films 20 of two decorative sheets 100 or decorative materials 200 are stacked facing each other in the thickness direction, the static friction coefficient between the opposing protective films 20 is 0.5 or less.

[0055] As a result, when the decorative sheet 100 or the decorative material 200 is transported, the frictional force generated between the overlapping protective films 20 can be prevented from peeling off the protective film 20 from the decorative sheet body 10. In other words, a decorative sheet 100 or a decorative material 200 can be realized in which the protective film 20 is unlikely to peel off during transportation, etc.

[0056] Although one embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and design modifications and the like within the scope of the present invention are also included. In addition, the components shown in the above-mentioned embodiment and the modified examples shown below can be appropriately combined to form a configuration.

[0057] (Variation 1) In the above embodiment, the protective film 20 of the decorative sheet 100 includes a release layer 8, but the embodiment of the decorative sheet is not limited to this. The protective film of the decorative sheet does not have to include a release layer.

[0058] Even if the protective film does not have a release layer, when two protective films of decorative sheets or decorative materials are stacked facing each other in the thickness direction, the static friction coefficient between the facing protective films may be 0.5 or less. For example, in a protective film that does not have a release layer, the surface (upper surface) of the protective film may be provided with an uneven shape by embossing so that the static friction coefficient between the facing protective films is 0.5 or less. In this case, the uneven shape is formed on the upper surface of the protective layer of the protective film.

[0059] (Variation 2) In the above embodiment, the decorative sheet body 10 of the decorative sheet 100 includes a transparent thermoplastic resin layer 4, but the form of the decorative sheet is not limited to this. The decorative sheet body of the decorative sheet does not have to include a transparent thermoplastic resin layer. In that case, the topcoat layer is provided on the upper side of the pattern printed layer.

[0060] The present invention will be described in detail below with reference to examples, but the present invention is not limited to the following examples.

[0061] Example 1 A polyethylene sheet having a thickness of 70 μm was prepared as the colored raw fabric layer 1. A pattern printed layer 3 was formed on the upper surface UP of the colored raw fabric layer 1 by printing urethane ink by gravure printing.

[0062] Next, polypropylene resin was applied to the upper UP surface of the pattern-printed layer 3 using an extruder to a thickness of 100 μm, and the surface (upper UP surface) was smoothed using a smooth embossing plate to form a transparent thermoplastic resin layer 4.

[0063] Next, a thermosetting resin (acrylic urethane resin) is applied to the upper surface UP of the transparent thermoplastic resin layer 4 in an amount of 4.0 to 5.0 g / m 2 Then, on the upper side UP, apply a thermosetting resin (silicone modified acrylic urethane resin) at a rate of 2.5 to 3.5 g / m 2 and cured at 40° C. to form a top coat layer 5. After the top coat layer 5 was formed, a decorative sheet body 10 was obtained.

[0064] A 60 μm thick polyethylene protective film coated with a long-chain alkyl pentane polymer resin as a release layer 8 was bonded to the upper UP surface of the decorative sheet main body 10, i.e., the upper UP surface of the top coat layer 5, as a protective film 20, to obtain the decorative sheet 100 of Example 1.

[0065] Example 2 A polypropylene sheet having a thickness of 60 μm was prepared as the colored raw fabric layer 1. A pattern printed layer 3 was formed on the upper surface UP of the colored raw fabric layer 1 by printing urethane ink by gravure printing.

[0066] Next, polypropylene resin was applied to the upper UP surface of the pattern-printed layer 3 using an extruder to a thickness of 90 μm, and an embossing plate was used to create an uneven shape on the surface (upper UP surface) to form a transparent thermoplastic resin layer 4.

[0067] Next, a thermosetting resin (acrylic urethane resin) is applied to the upper surface UP of the transparent thermoplastic resin layer 4 in an amount of 2.5 to 3.5 g / m 2 Then, apply a thermosetting resin on the upper side UP at a rate of 2.5 to 3.5 g / m 2 to form a top coat layer 5. After the top coat layer 5 was formed, a decorative sheet body 10 was obtained.

[0068] A 40 μm thick special polyolefin protective film having an embossed (uneven shape) surface was bonded to the upper UP surface of the decorative sheet main body 10, i.e., the upper UP surface of the top coat layer 5, using a laminator to obtain the decorative sheet 100 of Example 2.

[0069] Comparative Example 1 The decorative sheet of Comparative Example 1 was obtained in the same manner as in Example 1, except that a 60 μm thick polyethylene protective film having no embossing or release layer on its surface was attached to the upper surface of the decorative sheet body, i.e., the upper surface of the top coat layer, using a laminator.

[0070] Comparative Example 2 The decorative sheet of Comparative Example 2 was obtained in the same manner as Example 1, except that a 60 μm thick polyethylene protective film with general-purpose specifications (weak adhesion) was attached as a protective film to the upper surface of the decorative sheet body, i.e., the upper surface of the top coat layer, using a laminator.

[0071] (Test 1) Adhesion evaluation tests were conducted on the decorative sheets of Example 1-2 and Comparative Example 1-2. In the adhesion evaluation test, a tensile tester was used to measure the peel strength between the decorative sheet body and the protective film for a decorative sheet in which a protective film cut to a width of 1 inch was attached to the upper side of the decorative sheet body. The peel speed was 300 mm / min, and the peel angle was 180°.

[0072] (Test 2) A static friction coefficient measurement test was carried out on the decorative sheets of Example 1-2 and Comparative Example 1-2. In the static friction coefficient measurement test, a friction tester "Tribogear Muse 94i-II" manufactured by Shinto Scientific Co., Ltd. was used to calculate the static friction coefficient between the surface of the protective film and the surface of the same type of protective film.

[0073] Here, the same type of protective film refers to protective films of the same Example or Comparative Example in Example 1-2 and Comparative Example 1-2. For example, when carrying out a static friction coefficient measurement test on the decorative sheet 100 of Example 1, two protective films 20 of Example 1 were used to calculate the static friction coefficient between the protective films 20 of Example 1.

[0074] The static friction coefficient calculated in the static friction coefficient measurement test is the static friction coefficient between opposing protective films in two decorative sheets stacked with the protective films facing each other in the thickness direction.

[0075] (Test 3) A natural peeling evaluation test was carried out on the decorative sheets of Example 1-2 and Comparative Example 1-2. In the natural peeling evaluation test, the decorative sheets of Example 1-2 and Comparative Example 1-2 were left to stand for 5 days, and it was confirmed whether the protective film naturally peeled off from the decorative sheet body. The evaluation criteria were two-level, with "none" being considered a pass. None: The protective film did not peel off naturally from the decorative sheet itself. Yes: The protective film naturally peeled off from the decorative sheet body.

[0076] (Test 4) A peeling evaluation test during processing was carried out on the decorative sheets of Example 1-2 and Comparative Example 1-2. In the peeling evaluation test during processing, a substrate (wood substrate) was first attached to the lower side of the decorative sheets of Example 1-2 and Comparative Example 1-2 to obtain the decorative materials of Example 1-2 and Comparative Example 1-2.

[0077] Next, as shown in Fig. 3, two of the same kind of decorative materials were stacked with the protective films facing each other in the thickness direction, and a force was applied in the parallel direction F (width direction C) to move one of the decorative materials (decorative material 200B in the example of Fig. 3) relative to the other decorative material (decorative material 200A in the example of Fig. 3). When one of the decorative materials was moved, it was confirmed whether the protective film peeled off from the decorative sheet body.

[0078] Here, the same type of decorative material refers to a decorative material having a decorative sheet of the same Example or Comparative Example in Example 1-2 and Comparative Example 1-2. For example, when a peeling evaluation test during processing is performed on a decorative material 200 having a decorative sheet 100 of Example 1, both of the decorative materials 200A and 200B in FIG.

[0079] The evaluation criteria were two-level, with "none" being considered a pass. None: The protective film did not peel off from the decorative sheet itself. Yes: The protective film peeled off from the decorative sheet itself.

[0080] The peeling evaluation test during processing is a test that assumes that, for example, when decorative sheets or decorative materials are stacked and transported with the protective films facing each other in the thickness direction, one decorative sheet or decorative material may move relative to the other decorative sheet or decorative material due to vibrations or the like during transportation.

[0081] (Test Results) The results of tests 1-4 are shown in Table 1. The decorative sheets 100 of Examples 1 and 2, which had static friction coefficients of 0.5 or less calculated in Test 2, showed good results in Tests 3 and 4.

[0082] In Comparative Example 1 and Comparative Example 2, in which the static friction coefficient calculated in Test 2 was greater than 0.5, Comparative Example 1 failed Test 4. Comparative Example 2 also failed Tests 3 and 4.
