Description

[Technical field]

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

[0002] Conventionally, decorative materials printed with a wood grain pattern that is the same as natural wood have been used as building materials used for surface decoration of building walls, partitions, furniture, etc. This type of decorative material is required to have not only a two-dimensional design but also a three-dimensional design. As a decorative material that shows such a three-dimensional design, for example, a material that has a wood grain pattern pattern layer on a base material, a low gloss printed layer that becomes a vessel part on top of that, and a high gloss printed layer that becomes a wood skin part on top of that has been proposed (see Patent Documents 1 and 2). In addition, a decorative material is known that has a partial raised layer on the surface of the wood grain pattern printed layer including the vessel part, so that when a person touches the surface of the decorative material, a natural feel like touching natural wood is obtained (see Patent Document 3).

[0017] Hereinafter, an embodiment of the decorative material according to the present invention will be described with reference to the drawings. Note that each of the following drawings, including Fig. 1, is a schematic diagram showing the configuration of the decorative material according to the present invention. Therefore, the size and shape of each part are appropriately exaggerated to make it easier to understand. In addition, each figure except for Fig. 4 shows a mutually orthogonal coordinate system of XYZ or XZ. In this coordinate system, one direction when the decorative material 1 is viewed in the arrangement of Fig. 1 is the X direction, and the other direction perpendicular to the X direction is the Y direction. In addition, in the decorative material 1, the thickness direction (normal direction) perpendicular to the XY plane is the Z direction. The numerical values, shapes, materials, and the like described in this specification are merely examples of embodiments, and are not intended to be limiting, and may be appropriately selected and used.

[0018] Fig. 1 is a perspective view showing a portion of a decorative material 1 in an embodiment. Fig. 2 is a schematic cross-sectional view of the decorative material 1. Fig. 2 shows a cross section parallel to the XZ plane of the decorative material 1 shown in Fig. 1. Fig. 3 is a schematic cross-sectional view showing the internal structure of a unit protrusion 51. As shown in FIG. 1, the decorative material 1 of the present embodiment includes a substrate 10, a picture pattern layer 20, a low gloss layer 30, a surface protective layer 40, and a raised layer 50.

[0019] The substrate 10 is a member that serves as the base of the cosmetic material 1. As the substrate 10, for example, various paper materials, plastic films, plastic sheets, etc. can be appropriately selected depending on the application. These materials may be used alone, or may be laminated in any combination, such as a composite of paper, a composite of paper and plastic film, etc. The substrate 10 may also be wood, stone, concrete, glass, metal, ceramics, etc.

[0020] In particular, when a plastic film or a plastic sheet is used as the substrate 10, in order to enhance adhesion with a layer formed on the substrate 10, a physical or chemical surface treatment such as an oxidation method or a roughening method may be applied to one or both sides as necessary.

[0021] Examples of the oxidation method include corona discharge treatment, chromium oxidation treatment, flame treatment, hot air treatment, ozone and ultraviolet treatment, etc. Examples of the roughening method include sandblasting, solvent treatment, etc. These surface treatments are appropriately selected depending on the type of substrate 10, but generally, a corona discharge treatment method is preferably used. The substrate 10 may be subjected to other treatments to form a primer layer between the substrate 10 and the picture pattern layer 20, or may be painted to adjust the color, or may have a pattern formed in advance from a design point of view.

[0022] Examples of paper materials used as the substrate 10 include tissue paper, kraft paper, and titanium paper. These paper materials may further contain acrylic resin, styrene butadiene rubber, melamine resin, urethane resin, and the like (resin impregnation after papermaking or inclusion during papermaking). Examples include inter-paper reinforced paper and resin-impregnated paper.

[0023] Other examples of the paper include linter paper, paperboard, base paper for gypsum board, and vinyl wallpaper rolls with a vinyl chloride resin layer on the surface of the paper, which are often used in the field of building materials. Furthermore, coated paper, art paper, parchment paper, glassine paper, parchment paper, paraffin paper, Japanese paper, and the like, which are used in the field of office work, normal printing, packaging, and the like, can also be used. In addition, woven fabrics and nonwoven fabrics made of various fibers that have an appearance and properties similar to those of paper, although they are different from these papers, can also be used as the substrate 10. Examples of the various fibers include inorganic fibers such as glass fiber, asbestos fiber, potassium titanate fiber, alumina fiber, silica fiber, and carbon fiber, and synthetic resin fibers such as polyester fiber, acrylic fiber, and vinylon fiber.

[0024] Examples of the plastic film or sheet used as the substrate 10 include those made of various synthetic resins. Examples of the synthetic resin include polyethylene resin, polypropylene resin, polymethylpentene resin, polyvinyl chloride resin, polyvinylidene chloride resin, polyvinyl alcohol resin, vinyl chloride-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-vinyl alcohol copolymer resin, polyethylene terephthalate resin, polybutylene terephthalate resin, polyethylene naphthalate-isophthalate copolymer resin, polymethyl methacrylate resin, polyethyl methacrylate resin, polybutyl acrylate resin, polyamide resins such as nylon 6 or nylon 66, cellulose triacetate resin, cellophane, polystyrene resin, polycarbonate resin, polyarylate resin, and polyimide resin.

[0025] There is no particular limitation on the thickness of the substrate 10. When a film or sheet made of a plastic material is used as the substrate 10, the thickness is, for example, about 20 to 150 μm, and preferably in the range of 30 to 100 μm. When a paper material is used as the substrate 10, the basis weight is, for example, 20 to 150 g / m 2 Approximately 30 to 100 g / m 2 That's about it.

[0026] The picture pattern layer 20 is a wood grain pattern layer laminated on one surface of the substrate 10 (the upper surface in the Z direction in FIG. 1). The picture pattern layer 20 can be formed, for example, by printing directly on the substrate 10. As shown in FIG. 1 and FIG. 2, the picture pattern layer 20 has a vessel portion 20M as a part of the picture area. The vessel portion 20M is a pattern imitating the vessel grooves of the wood grain pattern. In the picture pattern layer 20, the picture area other than the vessel portion 20M becomes a wood grain portion (reference numerals are omitted). The wood grain portion is a pattern imitating the wood fibers of the wood grain pattern. In the following description, the pattern imitating the vessel grooves of the wood grain pattern is also referred to as a "vessel pattern". In addition, when the decorative material 1 is viewed in a plan view, the area that becomes the vessel portion 20M is also referred to as a "vessel portion", and the area that becomes the wood grain portion is also referred to as a "non-vessel portion".

[0027] The picture pattern layer 20 is formed, for example, by applying a colored layer and a wood grain patterned picture layer by gravure printing. In this case, a mixture of an acrylic resin and a colorant can be used as the colored layer. Also, a mixture of an alkyd resin and a nitrocellulose resin and a colorant can be used as the picture layer. The picture pattern layer 20 may be formed by printing or by transfer or the like. A primer layer may be provided to improve adhesion between the picture pattern layer 20 and the low gloss layer 30 (described later) laminated thereon.

[0028] The low gloss layer 30 is a transparent matte coating layer for expressing low gloss. The low gloss layer 30 of this embodiment is formed on the entire surface of the picture pattern layer 20. The 60 degree gloss (hereinafter, "G 30 ") and the 60 degree gloss of the surface protective layer 40 (hereinafter referred to as "G 40 The relationship between the 40 >G 30 In this way, by making the glossiness of the low gloss layer 30 smaller than that of the surface protective layer 40, the contrast difference between the surface protective layer 40 and the conduit portion 20M directly below the low gloss layer 30 exposed from the surface protective layer 40 becomes large, so that a visual three-dimensional effect can be obtained.

[0029] In the low gloss layer 30, examples of the resin that serves as the main component include urethane resin, unsaturated polyester resin, polyurethane resin (including two-component curing polyurethane resin), epoxy resin, alkyd resin, phenol resin, urea resin, diallyl phthalate resin, melamine resin, guanamine resin, silicon resin, polysiloxane resin, etc. Examples of matting agents contained in the resin include inorganic particles such as silica, alumina, kaolinite, calcium carbonate, magnesium carbonate, barium sulfate, and glass, and organic particles such as polycarbonate resins, (meth)acrylic resins, amide resins, urea resins, and silicone resins.

[0030] The surface protective layer 40 is a transparent gloss coat layer (high gloss layer) for protecting the surface of the decorative material 1. The surface protective layer 40 of this embodiment covers the surface except for the conduit portion 20M (picture pattern layer 20) located directly below the low gloss layer 30. In other words, the surface protective layer 40 is provided in a pattern area that matches with the wood grain portion of the wood grain pattern (picture pattern layer 20). The 60 degree gloss G of the surface protective layer 40 40 and the 60-degree gloss of the raised layer 50 (hereinafter, "G 50 The absolute value of the difference between the 50 -G 40 |) is set to be equal to or less than 5. The 60 degree gloss of the surface protective layer 40 is a value measured in an area of ​​the surface of the decorative material 1 where the raised layer 50 is not provided, using a gloss meter in accordance with, for example, the JIS Z 8741 standard. Surface protection layer 40 60 degree gloss G 40 and low gloss layer 30 with 60 degree gloss G 30 The relationship with G 40 >G 30 The 60 degree gloss G of the surface protective layer 40 is set to be 40 is set to be equal to or less than 10. Furthermore, as shown in Fig. 2, the surface height difference ΔZ between the surface protective layer 40 and the low gloss layer 30 is set to be equal to or less than 1 to 100 µm.

[0031] Examples of the resin that forms the surface protection layer 40 include a thermosetting resin, a thermoplastic resin, and an ionizing radiation curable resin. Examples of thermosetting resins include epoxy resins, phenolic resins, urea resins, unsaturated polyester resins, melamine resins, alkyd resins, polyimide resins, silicone resins, hydroxyl-functional acrylic resins, carboxyl-functional acrylic resins, amide-functional copolymers, and urethane resins.

[0032] Examples of thermoplastic resins include acrylic resins such as polymethyl (meth)acrylate and polyethyl (meth)acrylate; polyolefin resins such as polypropylene and polyethylene; polycarbonate resins; vinyl chloride resins; polyester resins such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN); acrylonitrile-butadiene-styrene resin (ABS resin); and acrylonitrile-acrylic ester resin.

[0033] The ionizing radiation curable resin is a resin that crosslinks and hardens by irradiation with electron radiation. Specifically, the ionizing radiation curable resin may be a mixture of at least one of prepolymers, oligomers, monomers, etc., each having a polymerizable unsaturated bond or an epoxy group in the molecule. The ionizing radiation means electromagnetic waves or charged particle beams that have an energy quantum capable of polymerizing or crosslinking molecules, and generally includes ultraviolet rays, electron beams, etc. Among the ionizing radiation curable resins, the electron beam curable resin is suitable for forming the surface protective layer 40 because it can be made solvent-free, does not require a photopolymerization initiator, and has stable hardening properties.

[0034] The raised layer 50 is a layer for imparting a tactile feel to the wood grain pattern of the picture pattern layer 20. As shown in Figs. 1 and 2, the raised layer 50 of this embodiment is provided on the surface of the surface protection layer 40. As described above, the 60 degree gloss G 50 is the 60 degree gloss G of the surface protective layer 40 40 The absolute value of the difference between 50 -G 40 |) is set to be equal to or less than 5. The 60 degree gloss of the raised layer 50 is a value obtained by measuring the surface of a portion of the raised layer 50 shown in FIG. 2 where unit convex portions 51 (described later) are densely packed using a gloss meter in accordance with, for example, the JIS Z 8741 standard.

[0035] The raised layer 50 is formed as an aggregate of a plurality of protrusions (hereinafter also referred to as "unit protrusions 51") as shown in Fig. 2. The unit protrusions 51 are formed when the raised layer 50 is formed on the low gloss layer 30, and the ink portions divided in the cells of the printing plate (not shown) are hardened independently without leveling each other on the transferred surface protective layer 40. Note that the unit protrusions 51 are desirably arranged around the conduits 20M (picture pattern layer 20) located immediately below the low gloss layer 30 in the surface protective layer 40, as shown in Fig. 1, for example.

[0036] The unit convex portion 51 has an average height of 5 μm or more and 40 μm or less. The unit convex portion 51 has an average outer diameter of, for example, about 200 μm. The interval between adjacent unit convex portions 51 is, for example, 20 to 30 μm. In each drawing, the size, shape, arrangement, etc. of the unit convex portion 51 are shown diagrammatically.

[0037] 3, each unit convex portion 51 (raised layer 50) is composed of resin 52, which serves as a binder, and filler (light diffusing particles) 53. To form raised layer 50, ink containing resin 52 and filler 53 is used. This ink has a higher viscosity than inks used in general gravure printing, and therefore, as described above, it hardens independently on transferred surface protective layer 40 without leveling with each other.

[0038] Examples of the resin 52 used in this ink include a thermosetting resin composition, an ionizing radiation curable resin composition, etc. Among these, two-component curing resins in which polyisocyanate is added as a curing agent to an acrylic, polyester, acrylic urethane, or urethane resin having functional groups such as hydroxyl, carboxyl, or amino groups as a vehicle component are particularly desirable from the standpoint of maintaining surface performance and production costs.

[0039] Examples of the filler 53 include organic particles such as acrylic beads, and inorganic particles such as aluminum hydroxide, silica, calcium carbonate, barium sulfate, alumina, and various ceramics. The average particle size of the filler 53 is, for example, about 10 to 30 μm. By including the filler 53 in the resin 52 forming the unit convex portion 51, fine irregularities are formed on the surface of the unit convex portion 51 by the filler 53. Therefore, a more natural touch can be imparted to the raised layer 50 formed on the surface of the cosmetic material 1. Note that, although the filler 53 is illustrated as a sphere in FIG. 3, the shape of the filler 53 is actually irregular, and the surface also has irregular irregularities.

[0040] The glossiness of the raised layer 50 can be changed by appropriately selecting the particle size and shape of the filler 53 contained in the ink that will become the raised layer 50. For example, when the particle size of the filler 53 is increased or when a filler having a shape close to a sphere is used, the light diffusion property is decreased and the glossiness is increased. When the particle size of the filler is decreased or when a filler having an irregular shape is used, the light diffusion property is increased and the glossiness is decreased. The content of the filler 53 is, for example, 20 to 40% by weight. EXAMPLES

[0041] Next, the decorative material according to the present invention will be described in more detail with reference to examples and comparative examples, although the form of the decorative material according to the present invention is not limited to the following examples.

[0042] In the layer structure shown in Fig. 2, seven types of decorative materials were produced as examples and comparative examples in which the absolute value of the difference in gloss between the raised layer 50 and the surface protective layer 40 and the average height of the raised layer 50 (unit convex portion 51) were changed, and a sensory evaluation of the design and tactile feel was performed for each decorative material. Note that in the examples and comparative examples, the 60 degree gloss G 40 is set to 10 or less, and the 60 degree gloss G of the surface protective layer 40 is set to 10 or less. 40 and low gloss layer 30 with 60 degree gloss G 30 The relationship between 40 >G 30In the examples and comparative examples, the surface height difference ΔZ (see FIG. 2) between the surface protective layer 40 and the low gloss layer 30 was set to 1 to 100 μm.

[0043] In Examples 1 to 4, the gloss difference was set between 0 and 5, and the average height T of the raised layer 50 was set between 5 and 40 μm. In Comparative Examples 1 to 3, the gloss difference was set between 5 and 10, and the average height T of the raised layer 50 was set between 0 and 20 μm. The type of ink forming the raised layer 50 and the blending of the resin and filler were the same in the Examples and Comparative Examples. The evaluation method will be described below.

[0044] Regarding design, the 60-degree gloss of each decorative material was measured in accordance with the standard JIS Z 8741 using a portable gloss meter GMX-202 manufactured by Murakami Color Research Laboratory. The superiority or inferiority of design was then judged based on whether the cell patterns of the raised layer 50 were easily noticeable. Specifically, the magnitude of the incongruity recognized between the raised layer 50 and the low gloss layer 30 exposed from the surface protective layer 40 was judged according to the following criteria. .circle.: There is no sense of incongruity between the low gloss layer 30 and the raised layer 50. ◯: There is little difference in contrast between the low gloss layer 30 and the raised layer 50. ×: There is a large sense of incongruity between the low gloss layer 30 and the raised layer 50.

[0045] Regarding the feel, the feel of the surface of each cosmetic material was judged according to the following criteria. ⊚: A sufficient sense of raisedness can be recognized by touching with the fingers. ○: A raised feeling can be recognized by touching with a finger. ×: The raised feeling is barely perceptible when touched with a finger. The evaluation results for each of the decorative materials in Examples 1 to 4 and Comparative Examples 1 to 3 based on the above items are shown in Fig. 4. Fig. 4 is a diagram showing the evaluation results for the Examples and Comparative Examples. In Fig. 4, "G60°" indicates the gloss level G60° of the raised layer 50 at 60 degrees. 50 and the surface protective layer 40 has a 60 degree gloss level G 40 The absolute value of the difference between 50 -G 40In addition, "T" represents the average height of the raised layer 50 (unit convex portion 51).

[0046] (Evaluation Results) The decorative materials of Examples 1 to 4 were found to have little or no incongruity between the low gloss layer 30 and the raised layer 50, and were confirmed to all have excellent design. Furthermore, the results showed that the decorative materials of Examples 1 to 4 provided a feeling of raised texture that was recognizable or sufficient to be recognized by touch, and all were confirmed to have an excellent feel to the touch.

[0047] In the decorative material of Comparative Example 1, the result was that there was little discomfort between the low gloss layer 30 and the raised layer 50. This is believed to be because the difference in gloss level in the decorative material of Comparative Example 1 was set to the same range as in the Examples. On the other hand, in the decorative material of Comparative Example 1, the result was that the raised feeling was hardly noticeable when touched with the fingers. This is believed to be because the average height T of the raised layer 50 in the decorative material of Comparative Example 2 was set to 0 μm. Thus, it was revealed that the decorative material of Comparative Example 1 was excellent in design but poor in tactility.

[0048] In the decorative material of Comparative Example 2, the result was that there was a large sense of incongruity between the low gloss layer 30 and the raised layer 50. This is thought to be because the difference in gloss level in the decorative material of Comparative Example 2 was set to 10. On the other hand, in the decorative material of Comparative Example 2, the result was that a sufficient raised feeling could be recognized by touch. This is thought to be because the average height T of the raised layer 50 in the decorative material of Comparative Example 2 was set to 20 μm, the same as in Example 2. Thus, it was revealed that the decorative material of Comparative Example 2 had an excellent feel to the touch, but was poor in design.

[0049] In the decorative material of Comparative Example 3, the result was that there was a large sense of incongruity between the low gloss layer 30 and the raised layer 50. This is thought to be because the difference in gloss level in the decorative material of Comparative Example 3 was set to 8. In addition, in the decorative material of Comparative Example 3, the result was that the raised feeling was hardly noticeable when touched with the fingers. This is thought to be because the average height T of the raised layer 50 in the decorative material of Comparative Example 3 was set to 2 μm. From the above results, it was clear that all of the decorative materials of Examples 1 to 4 were excellent in terms of feel and design.

[0050] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and various modifications and changes are possible, such as the modified forms described below, which are also included in the technical scope of the present invention. In addition, the effects described in the embodiment are merely a list of the most preferable effects resulting from the present invention, and are not limited to those described in the embodiment. The above-mentioned embodiment and the modified forms described below can be used in appropriate combination, but detailed description will be omitted. In the following description and drawings, the same reference numerals will be appropriately attached to parts that perform the same functions as the above-mentioned embodiment, and duplicated descriptions will be appropriately omitted.

[0051] (Variations) Decorative materials 1A to 1D of the first to fourth modified embodiments include a substrate 10, a wood grain design layer 20, a low gloss layer 30, a surface protection layer (high gloss layer) 40, and a raised layer 50, like decorative material 1 of the embodiment. FIG. 5 is a schematic cross-sectional view of a decorative material 1A of a first modified embodiment. As shown in Fig. 5, in the decorative material 1A of this embodiment, a surface protective layer 40 is laminated on the area of ​​the picture pattern layer 20 that will become the wood grain portion (non-vessel portion). In addition, in the decorative material 1A, the vessel portion 20M, which is part of the picture pattern layer 20, is formed to have a low gloss. That is, in the decorative material 1A, the vessel portion 20M of the picture pattern layer 20 is a layer having a vessel pattern and is also a low gloss layer (30). To give the vessel portion 20M of the picture pattern layer 20 a low gloss, for example, a matting material such as silica described above may be added to the resin in the part of the picture pattern layer 20 that will become the vessel portion 20M.

[0052] In the decorative material 1A of this embodiment, the absolute value of the difference in 60-degree gloss between the surface protective layer 40 and the raised layer 50 (|G 50 -G 40 |) is 5 or less, and the relationship between the surface protective layer 40 and the low gloss layer (the duct portion 20M of the pattern layer 20) is G 40 >G 30By setting the surface protective layer 40 to have the same effect as the decorative material 1 of the embodiment, the 60 degree gloss G 40 The average height of the raised layer 50 (unit convex portion 51) and the surface height difference ΔZ between the surface protection layer 40 and the picture pattern layer 20 (low gloss layer) are set within the same range as in the embodiment. According to the decorative material 1A of this embodiment, there is no need to laminate a low gloss layer 30 between the pattern layer 20 and the surface protection layer 40 as in the decorative material 1 of the embodiment (see Figure 2), so the overall layer thickness can be made thinner.

In this embodiment, the duct portion 20M of the picture pattern layer 20 is visually recognized as having a low gloss due to the low gloss layer 30 formed directly above it.

[0054] In the decorative material 1B of this embodiment, the absolute value of the difference in 60-degree gloss between the surface protective layer 40 and the raised layer 50 (|G 50 -G 40 |) is 5 or less, and the relationship between the surface protective layer 40 and the low gloss layer 30 is G 40 >G 30 By setting the surface protective layer 40 to have the same effect as the decorative material 1 of the embodiment, the 60 degree gloss G 40 The average height of the raised layer 50 (unit convex portion 51) and the surface height difference ΔZ between the surface protective layer 40 and the low gloss layer 30 are set within the same range as in the embodiment.

[0055] The configuration of the duct portion of the pattern layer 20 to have a low gloss is not limited to the above example. For example, the pattern layer 20 may not have the duct portion 20M, and the low gloss layer 30 may have a duct pattern in a portion that matches the duct portion. The entire pattern layer 20 may have a wood grain pattern, and a printed layer of a duct pattern may be provided directly below the low gloss layer 30 in a portion that matches the duct portion. In this case, the layer structure of the duct portion is the substrate 10, the pattern layer 20, the printed layer of the duct pattern, and the low gloss layer 30. Furthermore, the low gloss layer 30 may be formed in a portion of the pattern layer 20 that matches the duct portion 20M on the substrate 10, and the pattern layer 20 including the duct portion 20M may be provided on the low gloss layer 30. In this case, the layer structure of the duct portion is the substrate 10, the low gloss layer 30, and the pattern layer 20 (duct portion 20M). As described above, various configurations can be used to impart a low gloss to the vascular portion of the pattern layer 20.

[0056] FIG. 7 is a schematic cross-sectional view of a decorative material 1C of a third modified embodiment. 7, decorative material 1C of this embodiment differs from the second modified embodiment in that a raised layer 50 is provided only on the low gloss layer 30. In decorative material 1C of this embodiment, the other layer configurations are the same as decorative material 1B of the second modified embodiment.

[0057] In the decorative material 1C of this embodiment, the absolute value of the difference in 60-degree gloss between the surface protective layer 40 and the raised layer 50 (|G 50 -G 40 |) is 5 or less, and the relationship between the surface protective layer 40 and the low gloss layer 30 is G 40 >G 30 By setting the value so as to be equal to or larger than the value of the 60 degree gloss of the surface protective layer 40, the same effect as that of the decorative material 1 of the embodiment can be obtained. 40 The average height of the raised layer 50 (unit convex portion 51) and the surface height difference ΔZ between the surface protective layer 40 and the low gloss layer 30 are set within the same range as in the embodiment.

[0058] FIG. 8 is a schematic cross-sectional view of a decorative material 1D of a fourth modified embodiment. 8, decorative material 1D of this embodiment differs from the second modified embodiment in that a raised layer 50 is provided on both the low gloss layer 30 and the surface protective layer 40. In decorative material 1D of this embodiment, the other layer configurations are the same as decorative material 1B of the second modified embodiment.

[0059] In the decorative material 1D of this embodiment, the absolute value of the difference in 60-degree gloss between the surface protective layer 40 and the raised layer 50 (|G 50 -G 40 |) is 5 or less, and the relationship between the surface protective layer 40 and the low gloss layer 30 is G 40 >G 30 By setting the surface protective layer 40 to have the same effect as the decorative material 1 of the embodiment, it is possible to obtain the same effect as the decorative material 1 of the embodiment. 40 is measured in an area where the raised layer 50 is not provided. In addition, in the decorative material 1D of this embodiment, the 60 degree gloss G 40 The average height of the raised layer 50 (unit convex portion 51) and the surface height difference ΔZ between the surface protective layer 40 and the low gloss layer 30 are set within the same range as in the embodiment.

[0060] (Other variations) In the embodiment of the decorative material 1 (see FIG. 2), the picture pattern layer 20 may be omitted, and the low gloss layer 30 may be laminated on the substrate 10. Alternatively, the picture pattern layer 20 may be omitted, and a rough surface having the same gloss as the low gloss layer 30 may be formed on the surface of the substrate 10 on the surface side of the decorative material 1. That is, the low gloss layer 30 may be provided on one side of the substrate 10 as shown in FIG. 2, or may be provided on one side of the substrate 10 as a part of the substrate 10 as described above. In the embodiment, an example has been described in which the pattern layer 20 of the decorative material 1 has a wood grain pattern, but the pattern layer 20 may also have, for example, a pattern of laid tiles and joints, or a pattern of stacked bricks or concrete blocks and joints.
