Description

[Technical field]

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

[0002] Conventionally, decorative materials printed with wood grain patterns that are the same as natural wood have been used as building materials for surface decoration of building walls, partitions, furniture, etc. This type of decorative material is required to have not only two-dimensional design but also three-dimensional design. For this purpose, for example, a decorative material is known that has a partially raised layer formed on the surface of the decorative material, so that when a person touches the surface of the decorative material, the person feels a natural touch as if the person touched the surface of the decorative material (see, for example, Patent Documents 1 and 2).

[0013] 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 YZ. In this coordinate system, one direction when the decorative material 1 is viewed in the arrangement shown in 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.

[0014] (First embodiment) FIG. 1 is a perspective view showing a portion of a decorative material 1 of a first embodiment. 2 is a schematic cross-sectional view of the decorative material 1 of the first embodiment. 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 41. As shown in FIG. As shown in FIG. 1, the decorative material 1 of the first embodiment includes a substrate 10, a picture pattern layer 20, a gloss control layer 30, a raising layer 40, and a surface protection layer 50.

[0015] 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.

[0016] In particular, when a plastic film or a plastic sheet is used as the substrate 10, in order to enhance adhesion with a layer provided 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. 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.

[0017] Examples of paper materials used as the substrate 10 include tissue paper, craft 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.

[0018] In addition to the above-mentioned paper materials, various papers often used in the field of building materials, such as linter paper, paperboard, base paper for gypsum board, and vinyl wallpaper rolls with a vinyl chloride resin layer on the surface of the paper, can be used. 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, although they are different from these papers, woven fabrics and nonwoven fabrics made of various fibers that have an appearance and properties similar to those of paper can also be used as the substrate 10. Examples of 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.

[0019] 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.

[0020] 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.

[0021] The picture pattern layer 20 is a pattern layer formed 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. The picture pattern layer 20 has, for example, a pattern imitating wood grain. When the pattern of the picture pattern layer 20 includes a vessel portion, a raised layer 40 (described later) may be provided at a position corresponding to the vessel portion. The vessel portion is a pattern imitating the vessels of wood grain.

[0022] The picture pattern layer 20 is formed, for example, by applying a colored layer and a wood grain pattern 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 gloss adjustment layer 30 (described later) laminated thereon.

[0023] The gloss adjustment layer 30 is a transparent layer for expressing the gloss of the surface of the substrate 10. In this embodiment, the gloss adjustment layer 30 is formed on the entire surface of the picture pattern layer 20. In order to express low to high gloss, the gloss adjustment layer 30 has a 60 degree gloss level indicating a gloss value set to, for example, 4 to less than 70. In this embodiment, the gloss of the gloss adjustment layer 30 is recognized as the gloss of the surface of the substrate 10.

[0024] In the gloss adjustment 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, and the like. 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.

[0025] The raised layer 40 is a layer for imparting a tactile sensation to the picture pattern layer 20. Some raised layers 40 are formed as an assembly of a plurality of convex portions (hereinafter also referred to as "unit convex portions 41") that are separated and arranged with gaps 41G between them, as shown on the left side of FIG. 2. Other raised layers 40 are formed as an uneven body in which a plurality of unit convex portions 41 are leveled and fused together, and the gaps 41G disappear, as shown on the right side of FIG. 2. All raised layers 40 are laminated on the substrate 10 as a pattern layer having an uneven surface.

[0026] The unit convex portion 41 of the raised layer 40 (aggregate) is formed by forming the raised layer 40 on the gloss-adjusting layer 30, and each ink portion divided in the cells of the printing plate (not shown) is separated and independent from each other with a gap 41G between them on the transferred gloss-adjusting layer 30 without leveling each other, and is arranged without being fused and integrated with each other, and is cured. The average height of the unit convex portion 41 is, for example, about 5 to 20 μm, whereas the average height of a typical gravure printing printing layer (solid printing layer) is about 1 μm. The average outer diameter of the unit convex portion 41 is, for example, about 200 μm. The interval between adjacent unit convex portions 41 is, for example, 20 to 30 μm. Note that FIG. 2 shows the shape and arrangement of the unit convex portion 41 in the aggregate (the same applies to other figures).

[0027] As shown in FIG. 3, the unit convex portion 41 (raised layer 40) is composed of a resin 42 as a binder and a filler (light diffusing particles) 43. To form the raised layer 40, an ink containing the resin 42 and the filler 43 is used. The degree of leveling of the raised layer 40 can be adjusted by selecting the viscosity of the ink. For example, when an ink with a higher viscosity than that used in general gravure printing is selected, the inks do not level with each other on the transferred gloss adjustment layer 30 and fuse together, but harden in a state in which they are arranged separately and independently with gaps 41G between them, as described above. When an ink with a low viscosity is selected, the inks level with each other on the transferred gloss adjustment layer 30 and fuse together, and as a result, the inks harden in a state of unevenness without gaps 41G between them, as shown on the right side of FIG. 2. Even when inks of the same viscosity are used, depending on the conditions during film formation, leveled and unleveled raised layers may be mixed, as shown in Figure 2.

[0028] Resins 42 used in this ink include, for example, thermosetting resin compositions, ionizing radiation curing resin compositions, 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.

[0029] Examples of the filler 43 include organic particles such as acrylic resin beads and urethane resin beads, and inorganic particles such as aluminum hydroxide, silica, calcium carbonate, barium sulfate, alumina, and various ceramics. The average particle size of the filler 43 is, for example, about 10 to 30 μm. By including the filler 43 in the resin 42 forming the unit convex portion 41, fine irregularities are formed on the surface of the unit convex portion 41 by the filler 43. Therefore, a more natural touch can be imparted to the raised layer 40 formed on the surface of the decorative material 1. Note that, although the filler 43 is illustrated as a sphere in FIG. 3, the shape of the filler 43 is actually irregular, and the surface also has irregular irregularities.

[0030] The glossiness of the raised layer 40 can be adjusted by appropriately selecting the particle size, shape, and content of the filler 43 contained in the ink that will become the raised layer 40. For example, when the particle size of the filler 43 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 43 is, for example, 20 to 40% by weight.

[0031] In the protruding layer 40 of the first embodiment, the ratio B / A of the 60 degree glossiness of the protruding layer 40 (hereinafter also referred to as "glossiness B of the protruding layer 40") to the 60 degree glossiness of the substrate 10 (hereinafter also referred to as "glossiness A of the substrate 10") is set to be 0.6 to 0.9. In the first embodiment, the glossiness A of the substrate 10 is the glossiness measured in the area where the protruding layer 40 is not formed on the surface of the cosmetic material 1. For example, when the substrate 10 is exposed on the outermost surface of the cosmetic material 1, the glossiness of the surface of the substrate 10 itself is the glossiness A of the substrate 10. In addition, when the surface protective layer 50 is formed on the outermost surface layer of the substrate 10, the glossiness of the surface of the surface protective layer 50 is the glossiness A of the substrate 10. In addition, when the gloss adjustment layer 30 is formed on the outermost surface layer of the substrate 10, the glossiness of the surface of the gloss adjustment layer 30 is the glossiness A of the substrate 10. In the first embodiment, the gloss level B of the raised layer 40 is a measured value of the gloss of the underlying gloss control layer 30 and the gloss of the raised layer 40 in the area where the raised layer 40 is formed.

[0032] By setting the ratio of the glossiness A of the substrate 10 to the glossiness B of the protruding layer 40 within the above range, the cells of the protruding layer 40 become less noticeable regardless of the material of the substrate 10, so that the protruding layer 40 can have a natural appearance. The glossiness of the protruding layer 40 is not limited to the above-mentioned selection of the particle size and shape of the filler 43, and can also be adjusted, for example, by changing the application amount of the protruding ink containing a predetermined filler, or by adding a binder resin not containing a filler to the protruding ink. In the examples and comparative examples described later, the glossiness of the OP (overprint) layer formed on the substrate is regarded as the glossiness of the substrate.

[0033] The surface protective layer 50 is a transparent gloss coat layer (high gloss layer) for protecting the surface of the decorative material 1. The surface protective layer 50 is formed in the gloss adjusting layer 30 so as to cover the surface of the portion excluding the raised layer 40. Examples of resins that form the surface protective layer 50 include thermosetting resins, thermoplastic resins, and ionizing radiation curable resins. 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.

[0034] 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.

[0035] The ionizing radiation curable resin is a resin that is crosslinked and cured 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 50 because it can be made solvent-free, does not require a photopolymerization initiator, and has stable curing properties.

[0036] [Examples and Comparative Examples Based on the First Embodiment] Next, the decorative material 1 of the first embodiment will be described in more detail with reference to examples and comparative examples. However, the form of the decorative material according to the present invention is not limited to the following examples. A decorative material was produced with a layer structure excluding the picture pattern layer 20 and the surface protection layer 50 in the layer structure of the decorative material 1 shown in FIG. 2. Specifically, an ink with adjusted gloss was applied to the entire surface of the substrate to form an OP (overprint) layer. This OP layer corresponds to the gloss adjustment layer 30 of the first embodiment. The thickness of the OP layer was set to 2.0 to 3.0 μm. Next, a lattice-shaped raised print layer was formed on the OP layer by gravure printing using an ink of a resin composition mainly composed of an acrylic resin. This raised print layer corresponds to the raised layer 40 of the first embodiment. The maximum height of the raised print layer was set to about 25 μm.

[0037] 43 types of samples were produced by adjusting the parameters of the decorative material, such as the material of the base material, the 60 degree gloss of the OP layer, and the ratio of the 60 degree gloss of the raised print layer to the 60 degree gloss of the OP layer. The 43 types of samples were then divided into an example group, a comparative example 1 group, and a comparative example 2 group, and the design of the decorative materials in each group was evaluated.

[0038] In the example group, the 60 degree gloss of the OP layer and the 60 degree gloss of the raised print layer were adjusted so that the ratio B / A was 0.6 to 0.9. In the group of Comparative Example 1, the 60 degree gloss of the OP layer and the 60 degree gloss of the raised print layer were adjusted so that the ratio B / A was 0.2 to 0.4. In the group of Comparative Example 2, the 60 degree gloss of the OP layer and the 60 degree gloss of the raised print layer were adjusted so that the ratio B / A was 1.0 to 2.0. All groups used PET (polyethylene terephthalate resin) or paper as the substrate.

[0039] The 60 degree gloss of the OP layer and raised print layer was measured using a gloss meter "micro-TRI-gloss" manufactured by BYK in accordance with the standard JIS Z 8741. The superiority or inferiority of the design of each decorative material was then judged based on whether the cell grain of the raised print layer was noticeable or not. Specifically, the decorative material was attached to a vertical surface, and viewed from the front at a distance of 1m, and the presence or absence of a sense of incongruity (gloss difference) between the raised print layer and the OP layer was evaluated by 10 subjects. The number of subjects and their evaluations are as follows: ○: 8 to 10 people who have no sense of incongruity between the raised print layer and the OP layer. △: 6 to 7 people who have no sense of incongruity between the raised print layer and the OP layer. ×: 5 people or less where there is no sense of incongruity between the raised print layer and the OP layer.

[0040] The evaluation results for each group of Examples and Comparative Examples based on the above items are shown in Fig. 4. Fig. 4 is a diagram showing the evaluation results for each group of Examples and Comparative Examples based on the first embodiment. In FIG. 4, the items "OP layer" and "raised print layer" respectively indicate the ratio of clear ink to matte ink. For example, in the case of 8 clear ink and 2 matte ink, it is "8 / 2". "Matte" indicates 10 matte ink. "High matte" indicates an ink with even lower gloss than the above "matte". This "high matte" is formulated only with high matte ink, and does not contain clear ink. The item "Ratio B / A" indicates the ratio of the 60 degree gloss of the raised print layer to the 60 degree gloss of the OP layer. The item "OP layer A" indicates the 60 degree gloss of the OP layer. In the examples and comparative examples, the gloss of the OP layer formed on the substrate is regarded as the gloss of the substrate.

[0041] (Evaluation Results) In the case of the decorative materials belonging to the group of examples, most of the subjects reported that there was no sense of incongruity between the raised print layer and the OP layer, and it was confirmed that both had excellent design qualities. In the decorative materials belonging to the groups of Comparative Examples 1 and 2, the results showed that less than half or less than 70% of the subjects felt that there was no incongruity between the raised print layer and the OP layer, making it clear that the design was poor or was recognized as poor under certain conditions. This is thought to be because, in the group of Comparative Example 1, where the ratio B / A was 0.2 to 0.4, the gloss of the raised print layer was relatively too small compared to the gloss of the OP layer serving as the base layer, making the cell grain of the raised print layer more noticeable. Also, in the group of Comparative Example 2, where the ratio B / A was 1.0 to 2.0, the gloss of the raised print layer was relatively too large compared to the gloss of the OP layer serving as the base layer, making the cell grain of the raised print layer more noticeable. From the above results, it is clear that all of the decorative materials belonging to the example group are excellent in design.

[0042] Second embodiment In addition to the first embodiment described above, a decorative material is known in which a wood grain pattern layer is provided on a base material, a low gloss print layer is provided on the layer, and a high gloss print layer is partially provided on the layer to match the pattern layer, as a layer configuration that makes the wood grain look more three-dimensional. In the second embodiment, an example is described in which the gloss standard according to the third invention is applied to a decorative material having the above layer configuration and a raised layer.

[0043] 5 is a schematic cross-sectional view of a decorative material 1A of the second embodiment. In the explanation and drawings of the second embodiment, the same reference numerals as in the first embodiment are used for the same members as in the first embodiment, and duplicated explanations are omitted. The same applies to the other embodiments and modified forms described below. As shown in FIG. 5, the decorative material 1A of the second embodiment includes a substrate 10, a picture pattern layer 20, a low gloss layer 31, a raised layer 40, and a surface protective layer 50.

[0044] The picture pattern layer 20 of the second embodiment has a vessel portion 20M as a part of the picture area. The vessel portion 20M is a pattern that imitates the vessel grooves of a wood grain pattern. In the picture pattern layer 20, the picture area other than the vessel portion 20M is a wood grain portion (reference numerals omitted). The wood grain portion is a pattern that imitates the wood fibers of the wood grain pattern. In the following description, the pattern that imitates the vessel grooves of the wood grain pattern is also referred to as a "vessel pattern". In addition, although not shown, when the decorative material 1A is viewed in plan, 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". The resin and printing method that constitute the picture pattern layer 20 are the same as those of the first embodiment.

[0045] The low gloss layer 31 is a transparent matte coat layer for expressing a low gloss. The low gloss layer 31 of this embodiment is formed on the entire surface of the picture pattern layer 20. The resin and the like constituting the low gloss layer 31 are the same as those of the gloss adjustment layer 30 of the first embodiment. That is, the low gloss layer 31 of the second embodiment is a layer in which the gloss adjustment layer 30 of the first embodiment is adjusted to have a low gloss. The surface protection layer 50 covers the surface except for the vessel portion 20M (picture pattern layer 20) located directly under the low gloss layer 31. That is, the surface protection layer 50 of the second embodiment is provided in a pattern area that matches with the wood grain portion of the wood grain pattern (picture pattern layer 20) in a plan view.

[0046] The raised layer 40 is laminated on the surface protective layer 50. The unit convex portion 41 is preferably arranged around the duct portion 20M (picture pattern layer 20) located directly under the low gloss layer 31 in the surface protective layer 50. The glossiness B of the raised layer 40 is a value measured by a glossmeter on the surface of the decorative material 1A where the unit convex portions 41 are densely packed, for example, in accordance with the JIS Z 8741 standard. In the second embodiment, the glossiness B of the raised layer 40 is a measured value of gloss obtained by adding the glossiness of the underlying surface protective layer 50 and low gloss layer 31 and the glossiness of the raised layer 40 in the area where the raised layer 40 is formed. Note that the unit convex portions 41 of the raised layer 40 are arranged in harmony with the wood grain pattern, and therefore, as shown in FIG. 5, there are also areas on the surface protective layer 50 where the unit convex portions 41 are not provided.

[0047] In the decorative material 1A of the second embodiment, the ratio B / A of the glossiness B of the protruding layer 40 to the 60 degree glossiness A of the surface protective layer 50 directly under the protruding layer 40 (hereinafter also referred to as "glossiness A of the surface protective layer 50") is set to be 0.6 to 0.9. The glossiness A of the surface protective layer 50 is a value measured in an area on the surface of the decorative material 1A where the protruding layer 40 is not provided, using a glossmeter in accordance with, for example, the JIS Z 8741 standard. In the decorative material 1A of the second embodiment, by setting the ratio B / A of the glossiness B of the raised layer 40 to the glossiness A of the surface protection layer 50 to 0.6 to 0.9, a decorative material with excellent design can be obtained, as in the first embodiment.

[0048] Third embodiment FIG. 6 is a schematic cross-sectional view of a decorative material 1B according to a third embodiment. As shown in Fig. 6, decorative material 1B of the third embodiment differs from the second embodiment in that a raised layer 40 is provided only on the low gloss layer 31. In decorative material 1B of the second embodiment, the other layer configurations are the same as decorative material 1A of the second embodiment. In the decorative material 1B of the third embodiment, the ratio B / A of the glossiness B of the protruding layer 40 to the 60 degree glossiness A of the low gloss layer 31 directly under the protruding layer 40 (hereinafter also referred to as "glossiness A of the low gloss layer 31") is set to be 0.6 to 0.9. The glossiness A of the low gloss layer 31 is a value measured in an area of ​​the low gloss layer 31 on the surface of the decorative material 1B where the protruding layer 40 is not provided, using a glossmeter in accordance with, for example, the JIS Z 8741 standard. In the decorative material 1B of the third embodiment, by setting the ratio B / A of the glossiness B of the raised layer 40 to the glossiness A of the low-gloss layer 31 to 0.6 to 0.9, a decorative material with excellent design can be obtained, as in the first embodiment.

[0049] (Fourth embodiment) FIG. 7 is a schematic cross-sectional view of a decorative material 1C according to a fourth embodiment. 7, decorative material 1C of the fourth embodiment differs from the second embodiment in that a raised layer 40 is provided on both low gloss layer 31 and surface protective layer 50. In decorative material 1C of the fourth embodiment, the other layer configurations are the same as those of decorative material 1A of the second embodiment. In the decorative material 1C of the fourth embodiment, a low gloss layer 31 and a surface protective layer 50 are located directly below the raised layer 40. Therefore, as the gloss of the layer directly below the raised layer 40, for example, the average value of the 60 degree gloss of the low gloss layer 31 located directly below the raised layer 40 and the 60 degree gloss of the surface protective layer 50 located directly below the raised layer 40 (hereinafter also referred to as "average gloss A") can be used. In the decorative material 1C of the fourth embodiment, by setting the ratio B / A of the gloss level B of the raised layer 40 to the average gloss level A of the layer directly beneath the raised layer 40 to 0.6 to 0.9, a decorative material with excellent design properties can be obtained, as in the first embodiment.

[0050] [Examples and Comparative Examples Based on the Second Embodiment] Next, the decorative material 1A of the second embodiment 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. The decorative materials of the examples and comparative examples were produced based on the layer structure of the decorative material 1A shown in Fig. 5. Specifically, a thin building material base paper (basis weight 30 g / m 2 ) was prepared. This base paper corresponds to the substrate 10 of the second embodiment. Next, a design layer was formed on one side of the substrate sheet. First, an ink containing an acrylic resin and a colorant was applied to one side of the base paper by gravure printing to a thickness of 7 μm. Furthermore, a wood grain pattern was applied thereon to a thickness of 4 μm by gravure printing using an ink containing an alkyd resin and a nitrocellulose resin and a colorant. The design layer corresponds to the design layer 20 of the second embodiment.

[0051] Next, a matte coat layer having a thickness of 5 μm was formed on the entire surface of the picture pattern layer 20 by gravure printing using an ink containing acrylic polyol resin and silica particles (average particle size 3 μm) as a matte material. The matte coat layer corresponds to the low gloss layer 31 of the second embodiment. Next, a gloss coat layer having a thickness of 5 μm was formed by gravure printing in the area excluding the duct part of the picture layer so as to match the wood grain pattern using an ink containing acrylic polyol resin and silica particles (average particle size 3 μm) as a matte material. The gloss coat layer corresponds to the surface protection layer 50 of the second embodiment. The amount of the matte material was adjusted so that the gloss value (60 degree gloss) of the gloss coat layer was equal to or higher than that of the matte coat layer.

[0052] Next, using an ink containing an acrylic polyol resin and a filler (silica particles: average particle size 10 μm, acrylic resin beads: average particle size 10 μm), a raised print layer was formed by gravure printing using a pattern plate. This raised print layer corresponds to the raised print layer 40 of the second embodiment. In the examples and comparative examples, the content and type of filler were selected to adjust the gloss value of the raised print layer.

[0053] As a parameter of the decorative material, 23 types of samples were produced by adjusting the ratio of the 60 degree gloss of the raised print layer to the 60 degree gloss of the gloss coat layer that is the layer immediately below the raised print layer. The 23 types of samples were then divided into an example group, a comparative example 1 group, and a comparative example 2 group, and the design of the decorative materials in each group was evaluated.

[0054] In the example group, the 60 degree gloss of the gloss coat layer and the 60 degree gloss of the raised print layer were adjusted so that the ratio B / A was 0.6 to 0.9. In the group of Comparative Example 1, the 60 degree gloss of the gloss coat layer and the 60 degree gloss of the raised print layer were adjusted so that the ratio B / A was 0.3 to 0.5. In the group of Comparative Example 2, the 60 degree gloss of the gloss coat layer and the 60 degree gloss of the raised print layer were adjusted so that the ratio B / A was 1.0 to 1.5.

[0055] The 60-degree gloss of the raised print layer and the gloss coat layer was measured using a gloss meter "micro-TRI-gloss" manufactured by BYK in accordance with the standard JIS Z 8741. The superiority or inferiority of the design of each decorative material was judged based on whether the cell pattern of the raised layer 40 was difficult to notice. Specifically, the decorative material was attached to a vertical surface, and viewed from the front at a distance of 1 m, and the presence or absence of a sense of incongruity (gloss difference) recognized between the raised layer 40 and the surface protective layer 50 was evaluated by 10 subjects. The number of subjects and their evaluations are as follows: ○: 8 to 10 people who have no sense of incongruity between the raised print layer and the OP layer. △: 6 to 7 people who have no sense of incongruity between the raised print layer and the OP layer. ×: 5 people or less where there is no sense of incongruity between the raised print layer and the OP layer.

[0056] The evaluation results for each group of Examples and Comparative Examples based on the above items are shown in Fig. 8. Fig. 8 is a diagram showing the evaluation results for each group of Examples and Comparative Examples based on the second embodiment. In Fig. 8, "gloss value A" represents the 60 degree gloss of the gloss coat layer that is the layer immediately below the raised print layer. (Evaluation Results) In the case of the decorative materials belonging to the group of examples, most of the subjects reported that there was no sense of incongruity between the raised print layer and the gloss coat layer, and it was confirmed that both had excellent design qualities. In the decorative materials belonging to the groups of Comparative Examples 1 and 2, the results showed that less than half or less than 70% of the subjects felt that there was no incongruity between the raised print layer and the gloss coat layer, and it was revealed that the design was poor or was recognized as poor under certain conditions. This is thought to be because, in the group of Comparative Example 1, where the ratio B / A was 0.3 to 0.5, the gloss of the raised print layer was relatively too small compared to the gloss of the gloss coat layer, which is the base layer, making the cell grain of the raised print layer more noticeable. Also, in the group of Comparative Example 2, where the ratio B / A was 1.0 to 1.5, the gloss of the raised print layer was relatively too large compared to the gloss of the gloss coat layer, which is the base layer, making the cell grain of the raised print layer more noticeable. From the above results, it is clear that all of the decorative materials belonging to the example group are excellent in design.

In addition, the gloss adjustment layer 30 is provided on the picture pattern layer 20 in the picture area that is in harmony with the wood grain portion. The raised layer 40 is provided directly on the gloss adjustment layer 30.

[0061] In this embodiment, the 60 degree gloss of the conduit portion 20M (picture pattern layer 20) exposed from the gloss adjustment layer 30 (hereinafter also referred to as the "gloss of the conduit portion 20M") is set to be relatively smaller than the 60 degree gloss of the gloss adjustment layer 30. As shown in FIG. 11, the conduit portion 20M of the picture pattern layer 20 is exposed in the region on the surface of the decorative material 1F where the protruding layer 40 is not formed, and is exposed on the outermost layer of the decorative material 1F. Therefore, in this embodiment, the gloss of the conduit portion 20M is the gloss A of the base material 10. Moreover, the gloss B of the protruding layer 40 is a measured value of gloss obtained by adding the gloss of the protruding layer 40 and the gloss of the gloss adjustment layer 30 immediately below the area where the protruding layer 40 is formed. In the decorative material 1F of this embodiment, by setting the ratio B / A of the glossiness B of the raised layer 40 to the glossiness A of the base material 10 (glossiness of the duct portion 20M) to 0.6 to 0.9, a decorative material with excellent design properties can be obtained, similar to the decorative material 1 of the first embodiment.
