In particular, in production using a melt extrusion apparatus, it is more preferable to use a polyolefin resin as the resin film forming the base material 2 in consideration of productivity, environmental compatibility, mechanical strength, durability, price, etc. .

As the polyolefin resin, for example, polyethylene, polypropylene, polybutene, polymethylpentene, etc. can be used.

Examples of the polyester-based resin include polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyarylate, polycarbonate, copolymerized polyester (typically 1,4-cyclohexanedimethanol copolymerized polyethylene terephthalate resin commonly called PET- G) etc. can be used.

The thermoplastic resin to be colored may be appropriately selected from the resin films described above.

The thickness of the base material 2 is not particularly limited, and is preferably 10 μm or more and 200 μm or less, for example. It is more preferably 40 μm or more and 160 μm or less from the viewpoint of maintaining the concealability and ensuring the winding weight is light and the number of windings in continuous production.

(Pattern layer)
The decorative sheet 1 has a pattern layer 3.
The pattern layer 3 is a layer in which a first pattern, which is a pattern for imparting a design to the decorative sheet 1, is formed by printing, and is laminated on the opposite side of the transparent thermoplastic resin layer 5 to the gloss adjusting layer 4. formed by

As the first pattern, for example, it is possible to select a pattern suitable for the place where the decorative sheet 1 is used, such as wood grain, cork, stone grain, abstract pattern, or the like.

For example, it is preferable to use pigments of two or more colors to express the texture of real wood. In addition, a pearl pigment or the like may be used to express the texture of real wood.
The pattern layer 3 is preferable because the color tone of the first pattern 3a is stabilized by performing solid printing using the same color on the entire surface.

Weather resistance can be improved by adding an ultraviolet absorber, a light stabilizer, or the like to the printing ink that forms the pattern layer 3 .

As a method for printing the pattern, for example, known printing methods such as gravure printing, offset printing, silk screen printing, and inkjet printing can be used.

(gloss adjustment layer)
The decorative sheet 1 has a luster adjusting layer 4. - 特許庁
In the gloss adjusting layer 4, the pattern (first pattern 3a) and the uneven pattern 6a of the pattern layer 3 can be seen through, and the pattern (first pattern 3a) and the uneven pattern 6a of the pattern layer 3 are quasi-synchronized. It is a layer having a pattern (pattern) depending on the state of gloss.

The luster adjusting layer 4 may be formed by being laminated on the upper surface of the transparent thermoplastic resin layer 5, or may be formed by being laminated on the upper surface of a surface protective layer described later.
In the gloss adjusting layer 4, the pattern of the pattern layer 3 (first pattern 3a) and the uneven pattern 6a are formed when viewed from the direction in which the pattern layer 3, the transparent thermoplastic resin layer 5 and the gloss adjusting layer 4 are laminated. A second pattern is formed which is a pattern that is pseudo-synchronized with the pattern (third pattern). Moreover, the second pattern is a pattern for imparting a design to the decorative sheet 1, like the first pattern.

For the second pattern, it is possible to select a pattern suitable for the place where the decorative sheet 1 is used, such as wood grain, cork, stone grain, abstract pattern, etc., like the first pattern.

In the decorative sheet 1 of the present invention, the first pattern, which is the pattern formed by the pattern layer 3, and the second pattern, which is the pattern formed by the gloss adjusting layer 4, are arranged such that, when viewed from the thickness direction of the decorative sheet 1, The first pattern and the second pattern, which are patterns formed by the same outline, along the flow direction, which is the direction in which the sheet-shaped member is conveyed, when viewed from the thickness direction of the decorative sheet 1. The interval is smaller than the interval between the first pattern and the second pattern along the width direction, which is the direction orthogonal to the flow direction.

FIG. 2 is a schematic diagram showing the positional relationship between the first pattern and the second pattern.
As shown in FIG. 2, wood grain is selected as the first pattern 3a. Therefore, as shown in FIG. 2, the case where wood grain is selected as the second pattern 4a will be described.

FIG. 2 shows the first pattern 3a and the second pattern 4a viewed from the thickness direction of the decorative sheet 1. As shown in FIG. In FIG. 2, the first pattern 3a and the second pattern 4a represent wood grain, the first pattern is represented by dotted lines, and the second pattern 4a is represented by solid lines.
A flow L1 in FIG. 2 is the interval between the first pattern 3a and the second pattern 4a along the flow direction. The width L2 is the interval between the first pattern 3a and the second pattern 4a along the width direction.
When viewed from the thickness direction of the decorative sheet 1, the flow L1 is formed to be smaller than the width L2.

The flow L1 is 0.1 mm or more. The flow L1 is preferably 0.2 mm or more.
Moreover, the flow L1 is 0.5 mm or less. The flow L1 is preferably 0.4 mm or less.

The width L2 is 0.1 mm or more. The width L2 is preferably 0.5 mm or more, more preferably 0.8 mm or more.
Further, the width L2 is 1.5 mm or less. The width L2 is preferably 1.4 mm or less.

The design layer 3 and the gloss adjustment layer 4 are likely to be misaligned because they are repeatedly heated and cooled in the manufacturing process of the decorative sheet 1, but as described above, when viewed from the thickness direction of the decorative sheet 1, the flow L1 is By forming the decorative sheet so as to be smaller than the width L2, it is possible to obtain a decorative sheet having an excellent design close to the real thing while maintaining productivity.
The excellent productivity means that the production speed of the decorative sheet 1 can be maintained at 60 m/min or more.

The transparent resin forming the luster adjusting layer 4 is not particularly limited, and known transparent resins can be used.
Therefore, as the transparent resin forming the luster adjusting layer 4, for example, a composition obtained by adding a luster adjusting agent to a two-liquid curing urethane resin can be used.
As the two-pack curable urethane resin, for example, a urethane resin containing polyol as a main component and isocyanate as a cross-linking agent (curing agent) can be used.

Examples of gloss modifiers include fine particles of inorganic substances such as silica, alumina (α-alumina, etc.), calcium carbonate, barium sulfate, kaolinite, and aluminosilicate, or organic substances (resins) such as polycarbonate, nylon, and urethane resin. It is possible to use
It is preferable that the average particle diameter of the luster modifier is in the range of 1 μm or more and 10 μm or less.
The amount of the luster-adjusting agent to be added is appropriately selected according to the desired luster state of the pattern.

Fine particles other than those described above may be added to the luster adjusting layer 4 as necessary. Other fine particles include, for example, fillers such as clay, flame retardants such as magnesium hydroxide, antioxidants, lubricants, foaming agents, ultraviolet absorbers, light stabilizers, deodorants, antibacterial agents, antiviral agents, Examples include antiallergen agents, antifungal agents, antiallergen agents, and the like.
The amount of the additive added is preferably 10% by mass or less with respect to the total mass of the luster adjusting layer 4, for example.

The above antiviral agents can generally be broadly classified into inorganic and organic antiviral agents, and at least one of them can be included or used in combination.

Examples of the inorganic antiviral agents include those in which metal ions such as silver, copper, and zinc are supported on zeolite, apatite, zirconia, glass, molybdenum oxide, and the like.
As the inorganic antiviral agent, a silver-based antiviral agent is preferable from the viewpoint of having no biotoxicity and excellent safety. It is more preferable because even a small amount exhibits antiviral properties, so that the amount to be added can be suppressed.

When the silver-based antiviral agent is added to the gloss-adjusting layer 4 (or the surface protective layer 7 described later), the gloss-adjusting layer 4 (or the surface protective layer 7 described later) may cause discoloration (or In some cases, the color may be discolored by heat or light in the state, or may be discolored by heat or light after forming the gloss adjustment layer 4 or the surface protective layer 7 described later), but in this case, UV inhibitors, light stabilizers, etc. can be improved by timely addition of For example, when a benzotriazole compound is used for the silver molybdenum oxide double salt compound, an effect of improving discoloration can be expected.

Examples of the organic antiviral agents include quaternary ammonium salt, quaternary phosphonium salt, pyridine, pyrithione, benzimidazole, organic iodine, isothiazoline, and anionic agents.

Among the above organic antiviral agents, benzimidazole antiviral agents or anionic antiviral agents that maintain the particle shape are particularly preferably used. Maintaining the particle shape means that the particles exist in the form of particles without dissolving in the composition (ink before curing) containing the resin constituting the luster adjusting layer 4 . Therefore, in the process of forming the gloss adjusting layer 4, the particles of the imidazole compound or the particles of the anionic compound tend to float, and imidazole is added to the outermost surface side of the gloss adjusting layer 4 (or the side provided with the surface protective layer 7). It is possible to facilitate uneven distribution of the particles of the compound or the particles of the anionic compound. Then, by unevenly distributing imidazole-based compound particles or anionic compound particles on the outermost surface side (or the side provided with the surface protective layer 7) of the gloss-adjusting layer 4, the antiviral properties necessary for obtaining a predetermined antiviral property are obtained. Since the amount of the viral agent added can be suppressed, it is possible to easily suppress the deterioration of the surface properties such as the scratch resistance of the gloss adjusting layer 4 .

As the anionic antiviral agent, for example, one containing a styrene polymer derivative compound and a carboxylic acid derivative compound is preferable. In addition, the styrene polymer derivative compound and the carboxylic acid derivative compound preferably contain at least one structure among the structures of styrene, sodium sulfonate, acrylic acid, maleic acid, and fumaric acid, and more preferably contain all of the structures. . In general, enveloped viruses can be inactivated relatively easily by destroying their envelopes (lipid layers). Therefore, if only an effect against enveloped viruses is expected, only styrene polymer derivative compounds should be contained. In some cases, if only the resin alone is contained, sufficient effects can be obtained.

On the other hand, for non-enveloped viruses whose activity is difficult to inhibit, it may be necessary to increase the amount of the combination of styrene polymer derivative compounds and/or styrene resins. may impede the Therefore, in order to obtain a sufficient inhibition of activity against non-enveloped viruses, it is preferable to use the carboxylic acid derivative compound as a mixture. Using a compound containing all of triethylamine, N,N-dimethylallylamine, dimethylpyrrole, tetramethyl-1,3-propanediamine, and N,N,2,2-tetramethyl-1,3-propanediamine as constituent components of the compound is more preferred.

The compounds exemplified as the above anionic antiviral agents may be used alone or in combination depending on the purpose and application.

When the anionic antiviral agent is used, hydrophobic fine particles such as hydrophobized silica are preferably used as the luster modifier. This is for suppressing binding of the anionic antiviral agent to silica and suppressing deactivation of the anionic antiviral agent.

As the hydrophobized silica, it is possible to use hydrophobized hydrophilic silica produced by a known method. Untreated silica produced by a known method is usually hydrophilic silica, and hydrophobic silica is obtained by subjecting the hydrophilic silica to a hydrophobizing treatment to make it hydrophobic. A method for hydrophobizing untreated silica (hydrophilic silica) is not particularly limited, and a known method can be used.

The content of the antiviral agent is preferably 0.1% by mass or more and 10% by mass or less with respect to the total mass of the luster adjusting layer 4 .

By forming a luster-adjusting layer and a surface protective layer, which will be described later, on the transparent thermoplastic resin layer 5, it is possible to improve the tactile sensation, the three-dimensional effect due to reflection, and the durability of the decorative sheet 1.
