Modes for Carrying Out the Invention

[0012] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Attached to this specification In the drawings, for the convenience of illustration and easy understanding, the scale, the aspect ratio of the vertical and horizontal dimensions, etc. are appropriately changed and exaggerated from those of the actual object.

[0013] In order to clarify the relationship in the direction between the drawings, some of the drawings are provided with arrows with common reference numerals to indicate the common first direction D1, second direction D2, and third direction D3. The tip of the arrow side becomes the first side in each direction. An arrow directed forward from the paper surface along the direction perpendicular to the paper surface of the drawing is shown by a symbol with a dot in a circle as shown in FIG. 1. In the illustrated example , the third direction D3 is the normal direction of the cosmetic sheet 20. The illustrated flat cosmetic sheet 20 extends in a first direction D and a second direction D2. The first direction D and the second direction D2 are orthogonal to a third direction D3. The first direction D and the second direction D2 are orthogonal to each other.

[0014] 〔Cosmetic Sheet and Cosmetic Material〕 The cosmetic sheet 20 includes a design layer 40 and a raised layer 50. The design layer 40 displays a design. The design layer 40 shown in FIG. 1 has a pattern of the surface of wood. The raised layer 50 includes raised portions 55 provided in regions overlapping with some regions of the design layer 40 . The raised portions 55 include a binder resin 60, resin particles 61, and inorganic particles 62. The average particle diameter of the resin particles 61 is larger than the average particle diameter of the inorganic particles 62 .

[0015] In one embodiment, the cosmetic sheet 20 is devised to achieve both excellent touch and low gloss. As a specific configuration, the cosmetic sheet may have the configuration shown in FIGS. 2 to 4. The raised portion 55 may include convex portions 56 formed by the protrusion of the inorganic particles 62. In the example shown in FIG. 4, a concave portion 57 is formed between the inorganic particles 62A and the inorganic particles 62B. From the position where the minimum thickness TA in this concave portion 57 is located, the top of the inorganic particle 62A protrudes to the first side in the third direction D3.

[0016] According to the present embodiment, the thickness of a part of the raised portion 55 can be made to correspond to the average particle diameter of the resin particles 61, and the thickness of another part of the raised portion 55 can be made to correspond to the particle diameter of the inorganic particles 62. As a result, as shown in FIG. 3, the cosmetic sheet 20 has a region RX where the raised portion 55 is not provided, a region RZ where the resin particles 61 of the raised portion 55 protrude, and a raised portion 5 It includes a region RY whose thickness is set by the inorganic particles 62 of 5. The decorative sheet 20 has different heights in these three regions RX, RY, and RZ. When touching the decorative sheet 20, a strong tactile sensation is imparted from the resin particles 61 in the region RZ. Also, in the region RY where the thickness is defined by the inorganic particles 62, a strong tactile sensation is imparted due to the presence of the inorganic particles 62. In addition, as shown in FIGS. 2 and 4, the tops of the convex portions 56 are dispersed in the region RY. The tops of the dispersed convex portions 56 can express a complex tactile sensation.

[0017] Furthermore, the surface of the inorganic particles 62 has reduced gloss. In the region RY where the thickness is defined by the inorganic particles 62, the inorganic particles 62 protrude from the binder resin 60 and are exposed from the binder resin 60. Or, the inorganic particles 62 are located near the surface of the raised portion 55. Therefore,

[0018] the gloss of the raised portion 55 can be sufficiently reduced. As described above, excellent tactile sensation can be imparted to the decorative sheet 20 and the gloss of the decorative sheet 20 can be reduced. That is, various tactile sensations can be emphasized and imparted, and the gloss is reduced. Therefore, according to this decorative sheet 20, an artificial impression can be weakened and a natural texture can be created.

When a resin layer is laminated on the fibrous material layer as a base material, examples include wallpaper base stock in which a resin layer such as a vinyl chloride resin layer, an olefin resin layer, or an acrylic resin layer is laminated on the surface of the backing paper for wallpaper. are exemplified. Examples of the base material of wood-based materials include wood base materials made of woods such as cedar, cypress, pine, oak, oak, beech, walnut, lauan, teak, and rubber tree . The wood base material may be in a plate shape. The wood base material may be veneer, single veneer, plywood, laminated wood, particle board, fiber board, etc.

[0031] The base material may contain additives as necessary. When the material constituting the base material is a resin, add As additives, examples include inorganic fillers such as calcium carbonate and clay, flame retardants such as magnesium hydroxide, antioxidants, lubricants, foaming agents, ultraviolet absorbers, light stabilizers, etc. The content of the additives is not particularly limited as long as it does not inhibit processing characteristics, etc. The content of the additives is appropriately set according to requirements such as specific properties.

[0032] The shape and dimensions of the base material are not particularly limited. The shape and dimensions of the base material can be appropriately selected according to the use, desired various properties, and processing suitability. When the base material is in the flat plate shape of a film, sheet, or plate, the thickness of the base material is not particularly limited.

As the oxidation method, for example, corona discharge treatment, chromium oxidation treatment, flame treatment, hot air treatment, ozone-ultraviolet treatment method, etc. are exemplified. As the roughening method, sandblasting method, solvent treatment method, etc. are exemplified. These surface treatments are appropriately selected according to the type of the base material. Generally speaking, the corona discharge treatment method is preferable in terms of the effect of surface treatment and operability, etc.

[0034] 《Design layer》 The decorative sheet 20 may include a design layer 40 in order to improve the design property. The design layer 4 From the viewpoint of enhancing the weather resistance of 0, the design layer 40 may be disposed near the base material 30. The design layer 40 may be disposed between the base material 30 and the raised layer 50. Between the base material 30 and the raised layer 50 when having a primer layer described later, the design layer 40 may be positioned between the base material 30 and the primer layer The base material 30 may be positioned in the entire area of the decorative sheet 20, or may be positioned only in a partial area of the decorative sheet 2 0.

[0035] Examples of the design layer 40 include a colored layer formed by solidly coating ink; a pattern layer formed by printing ink as a pattern ; a metal thin film; etc. Examples of the pattern (design) expressed by the design layer 40 include wood grain patterns such as annual rings and conduit grooves on the surface of a wood board ; stone grain patterns on the surface of stone slabs such as marble and granite; cloth grain patterns on the surface of cloth; leather grain patterns on the surface of leather ; a tile pasting pattern including a joint groove; a brick stacking pattern including a joint groove; a sandblasted pattern; a matte pattern; a pattern formed by arranging a plurality of concave and convex stripes extending in directions parallel to each other (so-called "ten thousand - line - like concave - convex pattern" or "ray - engraved pattern"); abstract pattern patterns such as geometric patterns, characters, figures, polka dots, and floral patterns ; etc. ; etc.

[0036] The ink used for the colored layer and the pattern layer may be ink obtained by appropriately mixing a binder resin with colorants such as pigments and dyes, extender pigments, solvents, stabilizers, plasticizers, catalysts, curing agents, ultraviolet absorbers, light stabilizers, etc. The binder resin of the colored layer and the pattern layer is not particularly limited. The binder resin of the colored layer and the pattern layer is, for example, urethane resin, acrylic polyol resin, acrylic resin, ester resin, amide resin, butyral resin, styrene resin, urethane - acrylic copolymer, vinyl chloride - vinyl acetate copolymer resin, vinyl chloride - vinyl acetate - acrylic copolymer resin, chloride vinyl - vinyl acetate - acrylic copolymer resin, chloride vinyl - vinyl acetate - acrylic copolymer resin, chloride Examples of the resin include propylene resin, nitrocellulose resin, cellulose acetate resin, etc. . Also, various types of resins may be used, such as one-component curable resins and two-component curable resins with a curing agent such as an isocyanate compound.

[0037] The colorant is not particularly limited. Examples of the colorant include inorganic pigments such as carbon black (soot), iron black, titanium white, antimony white, lead yellow, titanium yellow, cadmium red, ultramarine blue, cobalt blue, etc.; organic pigments or dyes such as quinacridone red, isoindolinone yellow, nickel azo complex, phthalocyanine blue, azomethine azo black, etc.; metallic pigments composed of flaky foil pieces such as aluminum and brass; pearlescent pigments composed of flaky foil pieces such as titanium dioxide-coated mica and basic lead carbonate; etc. The content of the colorant is not particularly limited.

That is, the content of the colorant can be freely selected in an appropriate amount considering the above-mentioned elements. As an example, the content of the colorant may be 20 parts by mass or more and 500 parts by mass or less, 50 parts by mass or more and 300 parts by mass or less, or 70 parts by mass or more and 200 parts by mass or less, based on 100 parts by mass of the resin constituting the colored layer and the pattern layer.

[0038] The colored layer and the pattern layer may contain additives such as ultraviolet absorbers, light stabilizers, and colorants. The thickness of the colored layer and the pattern layer can be appropriately selected according to the desired pattern. The thickness of the colored layer and the pattern layer may be selected from the viewpoint of concealing the background color of the support 15 and improving the design property. The thickness of the colored layer and the pattern layer may be 0.5 μm or more and 20 μm or less, or 1 μm or more and 10 μm It may also be as follows, and may be 2 μm or more and 5 μm or less.

As the alloy, brass , bronze, stainless steel, etc. are exemplified. The film thickness of the metal thin film can be about 0.1 μm to 1 μm.

[0040] <Raised layer> The raised layer 50 reduces gloss. The raised layer 50 functions as a matte layer. The raised layer 50 imparts a tactile sensation. The raised layer 50 includes a raised portion 55 provided in a region overlapping a part of the design layer 40. As shown in FIG. 2, the raised layer 50 may include a plurality of raised portions 55 separated from each other. The raised layer 50 may include a single raised portion 55.

[0041] When the raised portion 55 is located in a part on the design layer 40, the decorative sheet 20 includes a region having the raised portion 55 and a region not having the raised portion 55. Thereby, a contrast in gloss can be formed and a three-dimensional effect perceptible visually can be imparted. The region having the raised portion 55 is recessed compared to the region not having the raised portion 55 and is more easily visible.

[0042] The ratio of the area where the raised portion 55 is provided to the total area of the design layer 40 is preferably 5% or more and less than 100%, more preferably 10% or more and 90% or less, still more preferably 15% or more and 80% or less, and even more preferably 30% or more and 70% or less.

[0043] When the raised portion 55 is located in a part of the total area on the design layer 40, that is, when the ratio of the area where the raised portion 55 is provided to the total area of the design layer 40 is less than 100%, the raised portion 55... The arrangement of 55 may be determined according to the design imparted by the decorative sheet 20. For example, when the decorative sheet 20 represents the "wood grain pattern" of a natural wood board as shown in FIG. 1 , considering elements constituting the wood grain pattern such as the tree species of the wood, the type of wood grain (board grain or straight grain; presence or absence of burl grain; presence or absence of vessel grooves, etc.), and the processing state of the wood board (planing treatment, floating treatment, etc.), a matte layer may be arranged at an appropriate position on the decorative sheet. In the case of a wood grain pattern having vessel grooves, the raised portion 55 may be arranged in both the vessel region and the non-vessel groove region. The raised portion 55 may be arranged only in the vessel region. The raised portion 5 5 may be arranged only in the non-vessel groove region. Arranging the raised portion 55 in the non-vessel groove region is preferable in reproducing the appearance and tactile sensation of a natural wood board. In the case of a floating wood board, the raised portion 55 may be arranged in both the early wood region 33A and the late wood region 33B. The raised portion 55 may be arranged only in the early wood region 33A. The raised portion 5 5 may be arranged only in the late wood region 33B. Arranging the raised portion 55 in the early wood region 33A is preferable in reproducing the appearance and tactile sensation of a floating wood board. In the case of a wood grain having knots, the raised portion 55 may be arranged only in the portion of the knot 33C. The raised portion 5 55 may be arranged only in the portion other than the knot 33C.

[0044] The raised portion 55 contains a binder resin 60, resin particles 61, and inorganic particles 62. The raised portion 5 5 has a partially different thickness. The decorative sheet 20 can impart both tactile sensation and low gloss due to the raised portion 55 having the above configuration. On the other hand, when the raised portion 55 does not have the above configuration, it is impossible to achieve both tactile sensation and low gloss for the following reasons. First, when the raised portion 55 does not contain inorganic particles 62 and contains only resin particles 61, the decorative sheet 2 The luster of 0 cannot be reduced. Also, when the raised portion 55 contains only the inorganic particles 62 and does not contain the resin particles 61, the raised portion 55 becomes whitened, the visibility of the design layer 40 deteriorates, and the design property of the decorative sheet 20 decreases. Also, when the raised portion 55 contains only the inorganic particles 62 and does not contain the resin particles 61, the luster of the raised portion 55 becomes extremely low and may lack a natural texture. Also, since the inorganic particles 62 have a lower adhesion to the binder resin 60 than the resin particles 61, they are more likely to fall off from the raised portion 55 than the resin particles 61. The inorganic particles 62 with a larger particle diameter are more likely to fall off from the raised portion 55. For this reason, when the raised portion 55 contains only the inorganic particles 62 and does not contain the resin particles 61, defects due to the fall-off of the inorganic particles 62 are likely to occur . Also, since the refractive index difference between the binder resin 60 and the inorganic particles 62 is relatively large , when the inorganic particles 62 fall off from the raised portion 55, the luster changes greatly. Also, even when the raised portion 55 contains the resin particles 61 and the inorganic particles 62, if the thickness of the raised portion 55 is not partially different, a sufficient tactile sensation cannot be imparted.

[0045] Also, when the raised portion 55 contains only the inorganic particles 62, it is difficult to achieve both a tactile sensation and low luster for the following reasons. Inorganic particles 62 such as silica for blending in ink are usually manufactured by a method of growing the particle diameter larger by synthesis. In the manufacturing method by synthesis described above, particles with a certain degree of uniform particle diameter can be manufactured, but the maximum particle diameter is limited to about 18 μm, and it is difficult to manufacture inorganic particles 62 with a large particle diameter. Thus, it is difficult to obtain inorganic particles 62 with a large particle diameter that can improve the tactile sensation. Also, as a manufacturing method of inorganic particles 62 such as silica, a method of pulverizing agglomerates of large inorganic particles 62 There is a manufacturing method. In the manufacturing method by grinding described above, inorganic particles 6 with a large particle size can be obtained. On the other hand, the particle size distribution becomes very wide, ranging from several tens of micrometers to several hundreds of micrometers. Therefore, the performance such as touch feeling and low gloss is not stable, and it is inappropriate as an additive to be blended into the ink.

[0046] 《Binder Resin》 Examples of the binder resin 60 include a thermoplastic resin and a cured product of a curable resin composition. From the viewpoint of scratch resistance, the cured product of the curable resin composition is preferable as the binder resin 60. That is, the binder resin may contain a cured product of a curable resin composition. The ratio of the cured product of the curable resin composition to the total amount of the binder resin is preferably 50% by mass or more, more preferably 70% by mass or more, still more preferably 90% by mass or more, and still more preferably 100% by mass.

[0047] Examples of the thermoplastic resin include acrylic resins, cellulose resins, urethane resins, vinyl chloride resins, polyester resins, polyolefin resins, polycarbonate, nylon, polystyrene, and ABS resins.

[0048] Examples of the cured product of the curable resin composition include a cured product of a thermosetting resin composition or a cured product of a radiation-curable resin composition. The cured product of the thermosetting resin composition is preferable in terms of surface performance such as scratch resistance and stain resistance. The cured product of the radiation-curable resin composition is excellent in surface performance such as scratch resistance and stain resistance, and is further excellent in maintaining performance over time.

[0049] The thermosetting resin composition is a composition containing at least a thermosetting resin, and becomes hard by heating. ​​​It is a resin composition to be cured. Examples of the thermosetting resin include acrylic resin, urethane resin, phenolic resin, urea melamine resin, epoxy resin, unsaturated polyester resin, silicone resin, etc. In addition to these thermosetting resins, a curing agent, a curing catalyst, etc. may be added to the thermosetting resin composition. Yes.

[0050] Among the thermosetting resin compositions, a two-component curing composition with a polyol-based resin as the main component and an isocyanate-based compound as the curing agent is preferable. Examples of the polyol-based resin include acrylic polyol, polyester polyol, etc.

[0051] The radiation-curable resin composition may be an electron beam-curable resin composition or an ultraviolet ray-curable resin composition. The electron beam-curable resin composition is preferable in that it requires no polymerization initiator, has little odor, and is less likely to be colored. When the upper part 55 contains an ultraviolet absorber described later, the electron beam-curable resin composition is likely to increase the crosslinking density of the upper part 55 and is likely to improve the scratch resistance and stain resistance.

[0052] The radiation-curable resin composition is a composition containing a compound having a radiation-curable functional group (hereinafter also referred to as "radiation-curable compound"). The radiation-curable functional group is a group that crosslinks and cures by irradiation with radiation. Examples of the radiation-curable functional group include functional groups having an ethylenic double bond such as (meth) acryloyl group, vinyl group, allyl group, etc. Examples of the radiation-curable functional group also include epoxy group and oxetanyl group. In this specification, the (meth)acryloyl group means an acryloyl group or a methacryloyl group is shown. In this specification, (meth)acrylate means acrylate or methacrylate. is shown. Ionizing radiation means those having energy quanta capable of polymerizing or crosslinking molecules among electromagnetic waves or charged particle beams. Ionizing radiation may be ultraviolet rays (UV) or electron beams (EB). Ionizing radiation includes electromagnetic waves such as X-rays and γ-rays, and charged particle beams such as α-rays and ion beams. Specifically, the ionizing radiation curable compound may be appropriately selected from polymerizable monomers and polymerizable oligomers (sometimes referred to as "polymerizable prepolymers") that have been conventionally used as ionizing radiation curable resins. The ionizing radiation curable compound is preferably a compound having two or more ethylenically unsaturated bond groups.

[0063] 《Inorganic Particles》 The inorganic particles 62 may be particles formed from one or more inorganic substances such as silica, alumina, zirconia, and titania. Among these, silica is preferable as the material of the inorganic particles 62. The inorganic particles may be spherical or amorphous. The inorganic particles 62 may be particles formed from one or more inorganic substances such as silica, alumina, zirconia, and titania. Among these, silica is preferable as the material of the inorganic particles 62. The inorganic particles may be spherical or amorphous. The inorganic particles 62 may be particles formed from one or more inorganic substances such as silica, alumina, zirconia, and titania. Among these, silica is preferable as the material of the inorganic particles 62. The inorganic particles may be spherical or amorphous.

[0064] When the average particle diameter of the inorganic particles is defined as D2, D2 is preferably 5 μm or more and 20 μm More preferably, the thickness is 7 μm or more and 17 μm or less, and even more preferably, the thickness is 10 μm or less. The upper limit is 15μm. By making D2 5μm or more, the gloss can be reduced. By making it 0 μm or less, D2 <D1の関係を満たしやすくなる。これにより、盛上 The thickness of part 55 varies in parts, thereby imparting a complex tactile sensation. In addition, the ratio of inorganic particles 62 having a particle diameter 20 μm or more larger than the average particle diameter to the total inorganic particles 62 is The ratio is preferably 30% or less, more preferably 20% or less, and even more preferably is preferably 10% or less, and more preferably 5% or less.

[0065] The particle diameter (μm) of the inorganic particles is the maximum width of the inorganic particles in the longitudinal section of the decorative sheet, i.e. That is, the particle diameter (μm) of the inorganic particles is as shown in Figures 3 and 4. , the maximum width, i.e., the maximum length, of the inorganic particle in the cross section along the normal direction D3 of the decorative sheet The average particle diameter (μm) of the inorganic particles is measured along a direction perpendicular to the normal direction of the decorative sheet. Thirty cross-sectional areas each having a length of 1000 μm were magnified and observed. The particle size of each inorganic particle is measured, and the average particle size of the 30 inorganic particles measured (μ m).

[0066] The content of the inorganic particles 62 is preferably 4 parts by mass with respect to 100 parts by mass of the binder resin. More preferably, the amount of the amine is from 7 parts by mass to 25 parts by mass. The content of the inorganic particles 62 is preferably 10 parts by mass or more and 20 parts by mass or less. By doing so, it is possible to reduce the gloss. By making the content of the inorganic particles 62 30 parts by mass or less, This prevents the matte layer from whitening, which reduces visibility, and prevents the gloss of the raised portion 55 from decreasing drastically. It is possible to suppress the natural texture from being impaired.

[0067] 《Relationship among resin particles, inorganic particles, and binder resin》 D1 indicating the average particle diameter of the resin particles and D2 indicating the average particle diameter of the inorganic particles satisfy D2 < D 1. And the upper part 55 includes a convex part 5 6 formed by the protrusion of the inorganic particles 62. Here, "the inorganic particles protrude" means that, as shown in FIG. 4, at least one inorganic particle 62A is located between adjacent other inorganic particles 62B and protrudes in the third direction D3 from the minimum thickness TA of the upper part 55. That is, at least a part of the inorganic particle 62A is located on the first side in the third direction D3, on the side away from the design layer 40 in the third direction D3 in the illustrated example, from the position where the minimum thickness TA of the upper part 55 is obtained. In the illustrated example, a concave portion 57 is formed between the inorganic particle 62A and the inorganic particle 62B. From the position where the minimum thickness TA in this concave portion 57 is obtained, the top of the inorganic particle 6 2A is located on the first side in the third direction D3. From the position where the minimum thickness TA in this concave portion 57 is obtained, the top of the inorganic particle 62B is located on the first side in the third direction D3 and is located.

[0068] According to this configuration, the thickness of a part of the upper part 55 can be made the thickness corresponding to the particle diameter of the resin particles 61, and the thickness of another part of the upper part 55 can be made the thickness corresponding to the particle diameter of the inorganic particles 62. As a result, as shown in FIG. 3, the decorative sheet 20 includes a region RX where the upper part 55 is not provided, a region RZ where the resin particles 61 of the upper part 55 protrude, and a region RY where the thickness is set by the inorganic particles 62 of the upper part 55. In the illustrated example, the upper part 55 includes. In the illustrated example, the upper part The thickness of the region where the resin particles 61 of 55 do not exist is the same as the particle diameter of the inorganic particles 62. The decorative sheet 20 has different heights in these three regions RX, RY, and RZ. When touching the decorative sheet 20, a strong tactile sensation is imparted from the resin particles 61 in the region RZ. Also, in the region RY where the thickness is defined by the inorganic particles 62, a strong tactile sensation due to the presence of the inorganic particles 62 is imparted. As a result, through the sense of touch, the three regions with different heights can be clearly perceived. In addition, in the region RY, the tops of the convex portions 56 are dispersed at a higher density than the resin particles 61. With the dispersed tops of the convex portions 56, a complex tactile sensation can be expressed. These enable a strong tactile sensation to be imparted with a rich expression. Furthermore, the surface of the inorganic particles 62 has a low gloss.

[0069] In the region RY where the thickness is defined by the inorganic particles 62, the inorganic particles 62 protrude from the binder resin 60 and are exposed from the binder resin 60. Or, the inorganic particles 62 are located near the surface of the raised portion 55. Therefore, the gloss of the raised portion 55 can be sufficiently reduced. Note that FIG. 2 shows only the inorganic particles 62 exposed from the binder resin 60. The resin particles 61 protrude from the binder resin 60. As shown in FIG. 3, the tops of the resin particles 61 may be covered by the binder resin 60 or may be exposed from the binder resin 60.

[0070] As described above, excellent tactile sensation can be imparted to the decorative sheet 20 and the gloss of the decorative sheet 20 can be reduced. That is, various tactile sensations can be emphasized and imparted, and the gloss is reduced. Therefore, according to this decorative sheet 20, the artificial impression is weakened and a natural texture is obtained.

[0071] In this way, excellent tactile sensation can be imparted to the decorative sheet 20 and the gloss of the decorative sheet 20 can be reduced. That is, various tactile sensations can be emphasized and imparted, and the gloss is reduced. Therefore, according to this decorative sheet 20, the artificial impression is weakened and a natural texture is obtained. can create. Due to the touch feeling and low glossiness of the cosmetic sheet 20, complex natural objects, such as the surface of wood or the surface of stone, can be represented more faithfully. This raised layer 50 is suitable for combination with the design layer 40 that displays natural objects.

[0072] In addition, the inorganic particles 62 have lower adhesion to the binder resin 60 than the resin particles 61. Therefore, the inorganic particles 62 are more likely to fall off from the raised part 55 than the resin particles 61. When D1 < D 2, the inorganic particles 62 are more likely to fall off from the raised part 55. On the other hand, if D2 < D1, it is possible to suppress the inorganic particles 62 from falling off from the raised part 55. Also, by setting D2 < D1, it is easy to realize a configuration in which the thickness of the raised part 55 is partially different.

[0073] In order to make the effects such as achieving both touch feeling and low gloss more remarkable, the following configuration may be adopted.

[0074] The average particle diameter of the resin particles 61 may be larger than the average thickness of the raised part 55. According to this example, the thickness of the raised part 55 at the position R2 where the resin particles 61 exist is significantly different from the thickness of the raised part 55 in the region R1 where the inorganic particles 62 exist. Therefore, the touch feeling imparted by the resin particles 61 can be made significantly different from the touch feeling imparted by the inorganic particles 62. Thereby, a more complex touch feeling can be imparted by the raised layer 50.

[0075] The average particle diameter D2 of the inorganic particles 62 may be made larger than half of the average thickness T of the raised part 55. That is, the relationship of T / 2 < D2 may be established. According to this example, the thickness of the raised part 55 does not become too thick with respect to the particle diameter of the inorganic particles 62. As shown in FIG. 3, the raised part 55 The thickness of the region where the resin particles 61 do not exist can be made the same as the particle diameter of the inorganic particles 62. Thus, it is possible to suppress the alignment of the inorganic particles 62 in the third direction D3 within the upper container portion 55. As a result, in the region R1 where the resin particles 61 do not exist in the upper container portion 55, the thickness of the upper container portion 55 tends to be a thickness corresponding to the particle diameter of the inorganic particles 62. Along with this, in this region R1, the inorganic particles 62 are exposed on the surface of the upper container portion 55, or the inorganic particles 62 are positioned near the surface of the upper container portion 55. As a result, the tactile sensation in the region R1 can be emphasized, and the gloss can be effectively reduced. Also, the area in contact with the binder resin 60 of the inorganic particles 62 becomes large and the detachment from the binder resin 60 can be effectively suppressed.

[0076] The thickness (μm) of the upper container portion is the length (μm) of the upper container portion along the normal direction of the decorative sheet . The average thickness (μm) of the upper container portion is the average value (μm) of the thicknesses measured at 30 locations every 100 μm in the direction orthogonal to the normal direction in the longitudinal section of the decorative sheet, that is, in the section along the normal direction of the decorative sheet .

[0077] Also, as shown in FIG. 4, the upper container portion 55 may have a recess 57 between two convex portions 56A and 56B. The convex portion 56A is one convex portion formed by the protrusion of one inorganic particle 62A. The convex portion 56B is another convex portion formed by the protrusion of another inorganic particle 62B. One inorganic particle 62A and another inorganic particle 62B are adjacent to each other in the direction orthogonal to the third direction D3, in the illustrated example, in the first direction D1. In this example, the thickness TA of the upper container portion 55 at at least one recess 57A is the average thickness of the upper container portion 55 ​​​​It may be smaller than the thickness T. The thickness TA of the raised portion 55 in at least one recess 57A is may be smaller than the particle diameter D2A of one inorganic particle 62A, and that of another inorganic particle 62B may be smaller than the particle diameter D2B. The thickness TA of the raised portion 55 in at least one recess 57A may be smaller than the average particle diameter D2 of the inorganic particles 62. According to any of these examples even so, in the region R1 where the resin particles 61 of the raised portion 55 do not exist, the inorganic particles 62 are exposed on the surface of the raised portion 55, or the inorganic particles 62 are positioned near the surface of the raised portion 55. As a result, the tactile sensation in the region R1 can be emphasized, and the gloss can be effectively

[0078] As shown in FIG. 4, the tops of at least some of the inorganic particles 62C may be exposed from the binder resin 60 . The inorganic particles 62C can effectively reduce the gloss of the decorative sheet .

[0079] The difference between D1 and D2 may be within a predetermined range in order to easily achieve both a tactile sensation and a low gloss. Specifically, D1 - D2 is preferably 15 μm or more and 60 μm or less, more preferably 25 μm or more and 50 μm or less, and still more preferably 30 μm or more and 45 μm or less .

[0080] The average particle diameter of the resin particles 61 may be larger than twice the average particle diameter of the inorganic particles 62. According to this example, the difference between the particle diameters of the resin particles 61 and 62 can be increased. And two peaks can be imparted to the particle size distribution of the particles 61 and 62 contained in the raised portion 55. Thereby, the tactile sensation caused by the resin particles 61 and the tactile sensation caused by the inorganic particles 62 can be made significantly different The average particle diameter of the resin particles 61 may be five times or less than the average particle diameter of the inorganic particles 62. By setting an upper limit on the difference between the average particle diameter of the resin particles and the average particle diameter of the inorganic particles 62, Both the inorganic particles 61 and the inorganic particles 62 are less likely to fall off from the binder resin 60.

[0081] The average thickness of the raised portion 55 at a position where the resin particles 61 are not present is the average particle size of the inorganic particles 62. It may be 80% or more and 130% or less of the diameter, or 85% or more and 125% or less of the diameter, or 90% or more and 1 According to this example, the thickness of the protruding portion 55 is smaller than the particle diameter of the inorganic particles 62. Therefore, in the protruding portion 55, the inorganic particles 6 are arranged in the third direction D3. As a result, the region R 2 where the resin particles 61 are not present in the protruding portion 55 can be prevented from being lined up. 1, the thickness of the protruding portion 55 tends to depend on the particle diameter of the inorganic particles 62. As a result, in the region R1, the inorganic particles 62 are exposed on the surface of the protruding portion 55. Alternatively, the inorganic particles 62 are located near the surface of the protruding portion 55. As a result, the catalytic activity in the region R1 is This can emphasize the texture and effectively reduce gloss.

[0082] The average thickness (μm) of the protruding portion at the position where no resin particles are present is The thickness (μm) was measured at 30 points at 100 μm intervals in the direction perpendicular to the normal direction. Among them, the average value (μm) of the measured values at the measurement points where the resin particles 61 were not present is taken as the value.

[0083] In order to achieve both a good feel and a low gloss, it is preferable to use the resin particles and the inorganic particles in a predetermined ratio. Specifically, the content of inorganic particles is preferably 40 parts by mass per 100 parts by mass of resin particles. Parts by weight or more and 200 parts by weight or less, more preferably 50 parts by weight or more and 150 parts by weight or less. Yes, more preferably, it is 60 parts by mass or more and 90 parts by mass or less.

[0084] 《Thickness》 The raised layer 50 may have a partially different thickness. The thickness of the raised portion 55 may be partially different. By doing so, the tactile sensation can be emphasized. In order to make the thickness of the raised portion 55 partially different, it is preferable to include particles with different particle diameters in the raised portion 55.

[0085] Furthermore, by forming the raised layer 50 by gravure printing using a gravure plate with a partially different plate depth, the thickness of the raised portion 55 can be made partially different, and the tactile sensation can be emphasized. The gravure plate has a large number of independent cells on its surface. In a gravure plate with a partially different plate depth, the depth of some cells is different from that of other cells. For example, the shallow cells may preferably have a depth of 5 μm or more and 40 μm or less, more preferably 10 μm or more and 30 μm or less. The deep cells may preferably have a depth of 40 μm or more and 150 μm or less, more preferably 60 μm or more and 120 μm or less. In a gravure plate with a partially different plate depth, a large amount of dulling layer ink is filled in the portion with a deep plate depth. A small amount of dulling layer ink is filled in the portion with a shallow plate depth. Therefore, by performing gravure printing with a gravure plate with a partially different plate depth, a raised portion 55 with a partially different thickness can be formed. Also, in a gravure plate with a partially different plate depth, resin particles with a large average particle diameter are likely to be filled in the portion with a deep plate depth. Inorganic particles with a small average particle diameter are likely to be filled in the portion with a shallow plate depth. By using a gravure plate with a partially different plate depth, in addition to the difference in the ink filling amount, due to the difference in the particles to be filled, the thickness of the raised portion 55 can be made different. ​ They are. The size of each cell of the gravure plate is so small that it cannot be easily recognized by humans. Similarly the interval between cells is also so short that it cannot be easily recognized by humans. After gravure printing, since the ink will spread, there may be a case where the printed areas of adjacent cells are connected. From these facts, when the raised layer 50 is formed by a gravure plate with partially different plate depths, the raised layer 50 as a whole can achieve both a tactile feel and a low gloss. As shown in FIGS. 2 and 3, in the case of having raised portions 55 separated from each other in each raised portion 55, a tactile feel and a low gloss can be achieved.

[0086] When the raised layer 50 defines a region R1 where the thickness of the raised portion 55 is more than 6 μm and not more than 20 μm, and a region R2 where the thickness of the raised portion 55 is more than 20 μm and not more than 55 μm, it is preferable to satisfy the following (1) and (2). (1) The ratio of R1 to the total area of the region where the raised portion 55 is provided is 35% or more and 55% or less. (2) The ratio of R2 to the total area of the region where the raised portion 55 is provided is 20% or more and 40% or less. By satisfying the above (1) and (2), it is possible to suppress the uniformity of the tactile feel and gloss in the plane of the raised layer 50. When the tactile feel in the plane of the raised layer 50 is made uniform, there may be a case of receiving an impression of an artificial object or the tactile feel itself may decrease due to few undulations. Also, when the gloss in the plane of the raised layer 50 is made uniform, the impression of an artificial object becomes stronger and it is difficult to express the appearance of natural objects such as natural wood. Therefore, by satisfying the above (1) and (2), the tactile feel can be more emphasized and the texture of natural objects can be enhanced.

[0087] The raised layer 50 further defines a region R0 where the thickness of the raised portion 55 is 6 μm or less, and the thickness of the raised portion 55 When defining the region with a thickness exceeding 55 μm as R3, it is preferable to satisfy the following (3) and (4). Preferably. (3) The ratio of R0 to the total area of the region where the raised portion 55 is provided is 20% or less. (4) The ratio of R3 to the total area of the region where the raised portion 55 is provided is 5% or less. By satisfying the above (3), the low can be effectively reduced. By satisfying the above (4), it is possible to suppress a decrease in the touch feeling due to the presence of an extremely thick region.

The thickness distribution of the raised portion 55 can be calculated, for example, by the following steps (X1) to (X3).
