Description

[Technical Field]

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

[0002] In recent years, with the growing awareness of net-zero energy houses (ZEH) and other housing facilities, highly insulating sashes, doors, and other fixtures that use polyvinyl chloride (PVC) resin as a component have begun to be used (see, for example, Patent Document 1 below). In such PVC resin fixtures, if PVC resin decorative sheets are used on the surface for decoration, taking environmental friendliness into consideration, they can be easily recycled.

[0003] Such PVC resin decorative sheets are typically produced by printing a pattern with ink onto a colored PVC resin substrate (approximately 100 μm thick) to form a pattern layer, and then superimposing a transparent PVC resin layer (approximately 100 μm thick) on top of the pattern layer, followed by a doubling (thermal lamination) process in which the layers are heated and pressed together.

[0004] [Patent Document 1] Japanese Patent Publication No. 2021-127678 Summary of the Invention [Problem to be solved by the invention]

[0005] In the PVC resin fittings described above, further resource conservation is required, and there is a strong demand for thinner PVC resin decorative sheets without reducing productivity, processability, etc. This demand is not limited to PVC resin fittings, but can arise in the same way for any PVC resin decorative member.

[0006] In view of the above, an object of the present invention is to provide a decorative sheet that can be made thinner and thus save resources without reducing productivity, processability, etc., and a decorative member that uses the same. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the decorative sheet of the present invention comprises a transparent raw fabric layer made of a light-transmitting polyvinyl chloride resin and a pattern layer printed on one side of the transparent raw fabric layer, wherein the transparent raw fabric layer contains 12 to 30 parts by mass of a high-molecular-weight polyester-based plasticizer per 100 parts by mass of the polyvinyl chloride resin, and has a thickness of 60 μm to 150 μm.

[0008] Furthermore, the decorative sheet according to the present invention is preferably the decorative sheet described above, further comprising a colored concealing layer having concealing properties, provided on the design layer.

[0009] Furthermore, the decorative sheet according to the present invention is preferably the decorative sheet described above, further comprising a surface protective layer having optical transparency and provided on the other side of the transparent raw fabric layer.

[0010] Furthermore, the decorative sheet according to the present invention is preferably the decorative sheet described above, wherein a gloss control layer is provided on a portion of the surface protective layer.

[0011] Furthermore, the decorative sheet according to the present invention is preferably the decorative sheet described above, in which recessed embossments are formed on the surface side.

[0012] On the other hand, in order to solve the above-mentioned problems, the decorative member of the present invention is characterized by comprising a substrate made of polyvinyl chloride resin, the above-mentioned decorative sheet arranged so that one side of the transparent raw fabric layer faces the substrate, and an adhesive layer that bonds between the substrate and one side of the transparent raw fabric layer of the decorative sheet.

[0013] Furthermore, in the decorative member according to the present invention, it is preferable that the base material is a component material of a fitting.

[0014] Furthermore, in the decorative member according to the present invention, it is preferable that the fixture is a sash or a door. [Effects of the Invention]

[0015] According to the present invention, the transparent raw fabric layer made of polyvinyl chloride contains 12 to 30 parts by mass of a high-molecular-weight polyester plasticizer per 100 parts by mass of polyvinyl chloride resin, and has a thickness of 60 μm to 150 μm.Therefore, a pattern layer can be printed on the transparent raw fabric layer without reducing productivity, processability, etc., so that the colored concealing layer can be made unnecessary or thinner, thereby further reducing resource consumption. [Brief explanation of the drawings]

[0016] [Figure 1] 1 is a cross-sectional view showing a schematic configuration of a main embodiment of a decorative sheet according to the present invention. [Figure 2] FIG. 2 is a cross-sectional view showing a schematic configuration of a main embodiment of a decorative member using the decorative sheet of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] The following describes embodiments of the decorative sheet and decorative member according to the present invention with reference to the drawings. Note that the present invention is not limited to the following embodiments described with reference to the drawings, and various technical matters described in each embodiment can be appropriately combined or substituted as necessary.

[0018] [Main embodiment] The main embodiments of the decorative sheet and decorative member according to the present invention will be described with reference to FIGS.

[0019] <Overall structure of decorative sheet> As shown in Fig. 1, a pattern layer 12, on which a pattern is printed with ink, is provided on one surface (the lower surface in Fig. 1) of a transparent raw fabric layer 11 made of a light-transmitting polyvinyl chloride (PVC) resin. A colored concealing layer 13 made of a PVC resin with concealing properties is provided on one surface (the lower surface in Fig. 1) of the pattern layer 12.

[0020] A light-transmitting surface protective layer 14 is provided on the other side (top surface in FIG. 1) of the transparent raw fabric layer 11. A gloss-adjusting layer 15 is provided on a part of the surface protective layer 14 on the other side (top surface in FIG. 1) of the surface protective layer 14 so as to match the pattern of the pattern layer 12. On the front side of the decorative sheet 10 having these layers 11-15, recessed embossments 10a are formed on the surface protective layer 14 and the transparent raw fabric layer 11 so as to match the pattern of the pattern layer 12, avoiding the gloss-adjusting layer 15.

[0021] <Transparent fabric layer 11> The transparent raw fabric layer 11 serves as a support for the decorative sheet 10 and is a layer for improving weather resistance. The transparent raw fabric layer 11 is made of a light-transmitting PVC resin film, and is colorless transparent, colored transparent, or translucent, with transparency that allows the pattern layer 12 to be seen through. The transparent raw fabric layer 11 made of PVC resin has flexibility and thermoplasticity, and is therefore excellent in formability and processability, and is also excellent in printability.

[0022] PVC resin can be used as a recycled substrate by melting and extruding it, and is easier to reuse by melting than olefin-based resins. As PVC resin, not only polyvinyl chloride resin obtained by homopolymerizing vinyl chloride monomer, but also copolymers obtained by copolymerizing vinyl chloride monomer with monomers copolymerizable with said vinyl chloride monomer can be used.

[0023] Examples of monomers copolymerizable with vinyl chloride monomer include vinyl esters such as vinyl acetate and vinyl propionate; acrylic esters such as methyl acrylate and butyl acrylate; methacrylic esters such as methyl methacrylate and ethyl methacrylate; maleic esters such as butyl maleate and diethyl maleate; fumaric esters such as dibutyl fumarate and diethyl fumarate; vinyl ethers such as vinyl methyl ether, vinyl butyl ether, and vinyl octyl ether; vinyl cyanides such as acrylonitrile and methacrylonitrile; olefins such as ethylene, propylene, butylene, and styrene; dienes such as isoprene and butadiene; vinylidene halides other than vinyl chloride, such as vinylidene chloride and vinyl bromide; and allyl phthalates such as diallyl phthalate. These monomers can be used alone or in combination.

[0024] The transparent raw fabric layer 11 preferably has a thickness of 60 μm or more and 150 μm or less, and more preferably 80 μm or more and 100 μm or less. A thickness of 60 μm or more allows the layer to fully function as a support and significantly improve weather resistance. A thickness of 150 μm or less allows the layer to reduce wasteful use of PVC resin while still maintaining sufficient productivity and processability, thereby reducing manufacturing costs.

[0025] Plasticizer The transparent raw fabric layer 11 contains 12 to 30 parts by mass (PHR) of a high-molecular-weight polyester plasticizer per 100 parts by mass (100 PHR) of PVC resin, which makes it easy to achieve good and stable productivity, processability, and durability throughout the year, in other words, in a temperature environment of about 0 to 40°C.

[0026] <Ultraviolet absorber> It is preferable that the transparent raw fabric layer 11 contains an ultraviolet absorber (UVA) since this can improve weather resistance. Examples of UVA include benzotriazole-based and triazine-based UVAs.

[0027] Examples of benzotriazole-based UVAs include 2-(2-hydroxy-5-t-butylphenyl)-2H-benzotriazole, 2-(5-methyl-2-hydroxyphenyl)benzotriazole, 2-[2-hydroxy-3,5-bis(α,α-dimethylbenzyl)phenyl]-2H-benzotriazole, 2-(3,5-di-t-butyl-2-hydroxyphenyl)benzotriazole, 2-(3-t-butyl-5-methyl-2-hydroxyphenyl)-5-chlorobenzotriazole, 2-(3,5-di-t-butyl-2-hydroxyphenyl)-5-chlorobenzotriazole, 2-(3,5-di-t-amyl-2-hydroxyphenyl)benzotriazole, 2-(2'-hydroxy-5'-t-octylphenyl)benzotriazole, and the like, as well as mixtures, modified products, polymers, and derivatives thereof.

[0028] Examples of triazine-based UVAs include hydroxyphenyltriazines such as 2-(4,6-diphenyl-1,3,5-triazin-2-yl)-5-[(hexyl)oxy]-phenol, 2-[4-[(2-hydroxy-3-dodecyloxypropyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine, 2-[4-[(2-hydroxy-3-tridecyloxypropyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine, and 2,4-bis(2,4-dimethylphenyl)-6-(2-hydroxy-4-isooctyloxyphenyl)-s-triazine, as well as mixtures, modified products, polymers, and derivatives thereof.

[0029] Triazine-based UVAs are preferred because the triazine skeleton is more likely to suppress bleeding than benzotriazole-based or benzophenone-based UVAs, and because they are chemically stable, they are more likely to retain UV absorption ability over a long period of time. Therefore, triazine-based UVAs can suppress discoloration even when used outdoors for a long period of time, and can be suitably used for outdoor fittings such as sashes and doors.

[0030] The transparent raw fabric layer 11 preferably contains 0.3 parts by weight (0.3 PHR) to 1.0 parts by weight (1.0 PHR) of UVA per 100 parts by weight (100 PHR) of PVC resin, and more preferably 0.5 parts by weight (0.5 PHR) to 0.8 parts by weight (0.8 PHR). This reliably improves the weather resistance of the decorative sheet 10, suppresses bleed-out, and also suppresses adverse effects on other physical properties of the transparent raw fabric layer 11.

[0031] <Light stabilizer> It is preferable that the transparent raw layer 11 contains a light stabilizer, since this can improve weather resistance. Examples of the light stabilizer include hindered amine light stabilizers (HALS).

[0032] Examples of HALS include 4-benzoyloxy-2,2,6,6-tetramethylpiperidine, 1,2,2,6,6-pentamethyl-4-piperidinyl (meth)acrylate, bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate, bis(1,2,2,6,6-pentamethyl-4-piperidyl)sebacate, bis(1-octyloxyloxy-2,2,6,6-tetramethyl-4-piperidinyl)sebacate, bis(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate, methyl(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate, methyl-4-piperidinyl) sebacate, 2,4-bis[N-butyl-N-(1-cyclohexyloxy-2,2,6,6-tetramethyl-4-piperidinyl)amino]-6-(2-hydroxyethylamine)-1,3,5-triazine), tetrakis(1,2,2,6,6-pentamethyl-4-piperidyl)-1,2,3,4-butanetetracarboxylate, bis-(1,2,2,6,6-pentamethyl-4-piperidyl)-2-(3,5-di-t-butyl-4-hydroxy-benzyl)-2-n-butylmalonate, and the like. Among these, those derived from decanedioic acid (sebacic acid) can be mentioned, such as bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate, bis(1,2,2,6,6-pentamethyl-4-piperidyl)sebacate, bis(1-octyloxyloxy-2,2,6,6-tetramethyl-4-piperidinyl)sebacate, bis(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate, and methyl(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate.

[0033] The transparent raw fabric layer 11 preferably contains 0.5 parts by mass (0.5 PHR) to 10 parts by mass (10 PHR) to 10 parts by mass (100 PHR) of HALS per 100 parts by mass (100 PHR) of PVC resin, more preferably 1 part by mass (1 PHR) to 8 parts by mass (8 PHR), and even more preferably 3 parts by mass (3 PHR) to 6 parts by mass (6 PHR). This reliably improves the weather resistance of the decorative sheet 10, suppresses bleed-out, and also suppresses adverse effects on other physical properties of the transparent raw fabric layer 11.

[0034] <Picture layer 12> The design layer 12 is a mixture of a binder resin and a colorant such as an organic pigment or an inorganic pigment, and can be printed as an ink dissolved or dispersed in a medium liquid on one side (the lower side in FIG. 1) of the transparent raw fabric layer 11 and dried to form a design. The ink can further contain various additives such as fillers, tackifiers, plasticizers, stabilizers, dispersants, antifoaming agents, leveling agents, surfactants, and desiccants as needed.

[0035] Examples of binder resins include PVC resins such as vinyl chloride-vinyl acetate copolymers and acrylic-vinyl chloride-vinyl acetate copolymers.

[0036] Examples of colorants include inorganic pigments such as carbon black, iron black, titanium white, antimony white, yellow lead, titanium yellow, red iron oxide, cadmium red, ultramarine blue, and cobalt blue; organic pigments (dyes) such as diketopyrrolopyrrole red, quinacridone red, isoindolinone yellow, nickel azo complexes, phthalocyanine blue, azomethine, and azo black; metal pigments such as aluminum and brass; and pearl pigments such as titanium dioxide-coated mica and basic lead carbonate.

[0037] Examples of the pattern include wood grain patterns, wood grain vessel patterns, cork patterns, stone patterns, joints, geometric patterns, coloring, etc. Examples of the printing method include gravure printing, offset printing, relief printing, flexographic printing, screen printing, inkjet printing, etc.

[0038] The thickness of the design layer 12 is preferably 1 μm or more and 10 μm or less. A thickness of 1 μm or more allows the design to be printed clearly. A thickness of 10 μm or less can reduce waste of ink and can prevent a decrease in workability during printing, thereby reducing manufacturing costs.

[0039] <Colored concealing layer 13> Like the design layer 12, the colored concealing layer 13 is a mixture of a binder resin and a colorant such as an organic or inorganic pigment, and is solid-printed as an ink dissolved or dispersed in a medium liquid onto the design layer 12 (the lower surface in Figure 1) and dried to become opaque and opaque so as to prevent light from passing through, thereby enabling the layer to exhibit concealing properties. The ink may further contain various additives such as fillers, tackifiers, plasticizers, stabilizers, dispersants, antifoaming agents, leveling agents, surfactants, and drying agents as needed.

[0040] As with the design layer 12, examples of the binder resin include PVC resins such as vinyl chloride-vinyl acetate copolymers and acrylic-vinyl chloride-vinyl acetate copolymers.

[0041] As the colorant, inorganic pigments are preferred, and examples thereof include calcium carbonate, titanium oxide, carbon black, silica, chromium, antimony, titanium composites, and various other oxides.

[0042] As with the design layer 12, printing methods include various printing methods such as gravure printing, offset printing, letterpress printing, flexographic printing, screen printing, and inkjet printing, as well as various coating methods such as gravure coating and roll coating.

[0043] The colored concealing layer 13 preferably has a thickness of 1 μm or more and 10 μm or less. A thickness of 1 μm or more ensures reliable concealment. A thickness of 10 μm or less can reduce wasteful use of ink and can prevent a decrease in workability during printing, thereby reducing manufacturing costs.

[0044] <Surface protective layer 14> The surface protective layer 14 is provided to impart functions such as weather resistance, scratch resistance, and stain resistance, and is colorless and transparent, colored and transparent, or translucent, with a transparency that allows the design layer 12 to be seen through. The surface protective layer 14 is provided by dissolving or dispersing a resin material in a medium liquid, coating it on the transparent raw fabric layer 11 (top surface in Figure 1), and drying it. The surface protective layer 14 can also contain various additives as needed, such as the UVA and HALS described above, as well as heat stabilizers, antiblocking agents, catalyst scavengers, colorants, light scattering agents, and gloss adjusters.

[0045] Examples of resin materials include urethane-based, acrylic-based, acrylic silicone-based, fluorine-based, and epoxy-based materials.

[0046] The surface protective layer 14 preferably contains UVA in the range of 1 part by weight (1 PHR) to 30 parts by weight (30 PHR) per 100 parts by weight (100 PHR) of resin material. This reliably improves the weather resistance of the decorative sheet 10, suppresses bleed-out, and also suppresses adverse effects on other physical properties of the surface protective layer 14. Here, it is preferable that the combined UV (380 nm) transmittance of the surface protective layer 14 and the transparent substrate layer 11 is adjusted to 20%T or less.

[0047] The surface protective layer 14 preferably contains HALS in the range of 1 part by mass (1 PHR) to 30 parts by mass (30 PHR) per 100 parts by mass (100 PHR) of resin material, thereby reliably improving the weather resistance of the decorative sheet 10, suppressing bleed-out, and further suppressing adverse effects on other physical properties of the surface protective layer 14.

[0048] The surface protective layer 14 can be formed by various coating methods such as gravure coating, reverse coating, gravure reverse coating, die coating, and flow coating, and can also be formed by a printing method similar to that used for the design layer 12.

[0049] The surface protection layer 14 has a thickness of 2 μm or more and 20 μm or less, i.e., a dry solid content of 2 g / m 2 More than 20g / m 2 It is preferable that the thickness is 2 μm or more, that is, the dry solid content is 2 g / m 2 When the thickness is 20 μm or less, that is, when the dry solid content is 20 g / m or less, the weather resistance can be improved. 2 If the thickness is equal to or less than this, it is possible to prevent deterioration in processability, and also possible to prevent wasteful use of resin material, thereby achieving reduction in manufacturing costs.

[0050] <Gloss Adjustment Layer 15> The gloss adjustment layer 15 is made of a resin material such as a two-component curing urethane resin, contains additives such as a gloss adjustment agent, and is printed on the surface protection layer 14 (upper surface in FIG. 1) in harmony with the pattern of the pattern layer 12 and cured, thereby being provided on a part of the surface protection layer 14. An example of a two-component curing urethane resin is a urethane resin that has polyol as its main component and isocyanate as a crosslinking agent (curing agent).

[0051] Examples of gloss adjusters (matting agents) include inorganic substances such as silica, alumina (such as α-alumina), calcium carbonate, barium sulfate, kaolinite, and aluminosilicate, as well as particulate substances such as fine particles of organic substances (resins) such as polycarbonate, nylon, and urethane resin.

[0052] The gloss adjuster preferably has a particle size distribution peak in the range of 1 μm to 10 μm. If the particle size is 1 μm or more, clogging of the printing plate is less likely to occur during printing coating. If the particle size is 10 μm or less, the gloss adjuster is less likely to chip even when subjected to impact, and deterioration of scratch resistance and gloss can be suppressed.

[0053] The content of the gloss adjusting agent is preferably 1% by mass or more and 30% by mass or less. When the content is 1% by mass or more, gloss adjustment (matt) can be sufficiently performed. On the other hand, when the content is 30% by mass or less, sufficient transparency can be ensured.

[0054] The gloss adjusting layer 15, like the design layer 12, can be provided by a printing method such as gravure printing, offset printing, letterpress printing, flexographic printing, screen printing, or inkjet printing.

[0055] The thickness of the gloss adjustment layer 15 is preferably in the range of 1 μm to 10 μm. A thickness of 1 μm or more allows for sufficient gloss adjustment. On the other hand, a thickness of 10 μm or less makes the missing portion less noticeable even if the layer is chipped due to an impact.

[0056] <Overall configuration of decorative components> As shown in Figure 2, decorative sheet 10 is disposed on the surface (top surface in Figure 2) of component 101, such as a sash or door, which is made of PVC resin as a base material, with colored concealing layer 13, which is one side (bottom surface in Figure 2), of transparent raw fabric layer 11 facing toward it. An adhesive layer 102 made of PVC resin is disposed between colored concealing layer 13 of decorative sheet 10 and the surface of component 101. In other words, decorative member (door and fixture) 100 is formed by adhering colored concealing layer 13 of decorative sheet 10 to the surface of component 101 via adhesive layer 102.

[0057] <Component Materials 101> The component 101 constitutes fittings such as sashes and doors, and is made of PVC resin.

[0058] <Adhesive layer 102> The adhesive layer 102 is applied to the decorative sheet 10 as an adhesive in which an adhesive resin is dissolved or dispersed in a medium liquid, and is then attached to the component 101 and dried, thereby adhering the decorative sheet 10 to the component 101.

[0059] Examples of adhesive resins include urethane-based, acrylic-based, polyester-based, vinyl chloride-vinyl acetate copolymers, acrylic-vinyl chloride-vinyl acetate copolymers, etc. In particular, PVC resin-based resins such as vinyl chloride-vinyl acetate copolymers and acrylic-vinyl chloride-vinyl acetate copolymers are highly preferred from the viewpoint of recyclability.

[0060] The adhesive may contain various additives such as fillers, tackifiers, plasticizers, stabilizers, dispersants, antifoaming agents, leveling agents, surfactants, and desiccants as needed. The adhesive layer 102 preferably has a thickness of 0.5 μm or more and 6 μm or less. The adhesive layer 102 may be formed by various coating methods such as gravure coating, reverse coating, gravure reverse coating, die coating, and flow coating.

[0061] <Method for manufacturing the decorative sheet 10 and the decorative member 100> The manufacturing method of the decorative sheet 10 and decorative member 100 according to this embodiment will be described below. First, a transparent PVC resin is mixed with a plasticizer and additives such as UVA and HALS, and the mixture is molded into a sheet shape, while forming embossments 10a using an embossing plate or the like, to obtain a transparent raw fabric layer 11.

[0062] A pattern is then printed on the back side of the transparent raw fabric layer 11 using a pattern ink made by mixing a binder resin and a colorant in a liquid medium, and dried and cured to form a pattern layer 12. Subsequently, a hiding ink made by mixing a binder resin and a colorant in a liquid medium is solid printed on the pattern layer 12, and dried and cured to form a colored hiding layer 13. Subsequently, a liquid made by mixing a transparent resin material and an additive such as UVA or HALS in a liquid medium is applied to the front side of the transparent raw fabric layer 11, and dried and cured to form a surface protection layer 14.

[0063] Furthermore, a resin material such as a two-component curing urethane resin is mixed with an additive such as a gloss adjuster, and printed on the surface side of the surface protection layer 14 so as to match the pattern 12a of the pattern layer 12, and then cured to provide a gloss adjuster layer 15. This allows the decorative sheet 10 to be obtained in-line (in one pass).

[0064] Finally, an adhesive prepared by mixing an adhesive resin and various additives in a medium liquid is applied onto the colored concealing layer 13 of the decorative sheet 10 to form an adhesive layer 102, which is then adhered to the component material 101 and dried and hardened to obtain the decorative element 100.

[0065] <Action and effect> As explained above, the decorative sheet 10 according to this embodiment contains 12 to 30 parts by mass of a high-molecular-weight polyester plasticizer per 100 parts by mass of PVC resin, and has a transparent raw fabric layer 11 with a thickness of 60 μm to 150 μm. This allows for satisfactory productivity and processability, while also allowing a pattern to be printed with a pattern ink on the back surface of the transparent raw fabric layer 11 to form a pattern layer 12. Therefore, a PVC resin concealing ink can be solid-printed on the pattern layer 12 to form a colored concealing layer 13.

[0066] Therefore, according to the decorative sheet 10 of this embodiment, the colored concealing layer 13 can be made thin (1 μm or more and 10 μm or less) without reducing productivity, processability, etc., thereby achieving further resource conservation.

[0067] Furthermore, because the colored concealing layer 13 is formed by printing a concealing ink, the doubling (thermal lamination) process can be omitted, and only the printing (coating) process is required from the formation of the pattern layer 12 to the formation of the gloss-adjusting layer 15. Therefore, the decorative sheet 10 can be manufactured in-line (in one pass), which significantly reduces the labor and energy consumed in manufacturing.

[0068] Furthermore, since the transparent raw fabric layer 11 is made of PVC resin and the binder resin of the pattern layer 12 and the colored concealing layer 13 is also PVC resin-based, the recyclability of the decorative component (fittings) 100 such as sashes and doors in which the decorative sheet 10 is attached to the PVC resin component 101 can be greatly improved, thereby reducing the environmental burden.

[0069] [Other embodiments] In the above-described embodiment, the decorative sheet 10 and the decorative member 100 using the same are described, in which the pattern layer 12 and the colored concealing layer 13 are formed using ink that uses a PVC resin-based binder resin, but the present invention is not limited to this. In other embodiments, for example, the pattern layer and the colored concealing layer can be formed using ink that uses an acrylic resin-based binder resin that has high adhesion to PVC resin.

[0070] However, as in the above-mentioned embodiment, if the decorative sheet 10 is made using ink that uses a PVC resin-based binder resin to form the pattern layer 12 and the colored concealing layer 13, this is highly preferable because it can further improve the recyclability of the decorative member (fitting) 100 that is attached to a sash, door, etc. made of PVC resin component 101.

[0071] In the above-described embodiment, the decorative sheet 10 provided with the colored concealing layer 13 and the decorative member 100 using the same have been described, but the present invention is not limited to this. As another embodiment, for example, depending on conditions such as the color of the component 101, it is also possible to use a decorative sheet and a decorative member using the same that omit the colored concealing layer 13.

[0072] In the above-described embodiment, the decorative sheet 10 is provided with a gloss-adjusting layer 15 containing a matting agent, but the present invention is not limited to this. As another embodiment, for example, depending on the design of the design layer 12, it is possible to provide a decorative sheet provided with a gloss-adjusting layer containing a gloss agent instead of a matting agent, and a decorative member using the same.

[0073] In the above-described embodiment, the decorative sheet 10 and the decorative member 100 using the same are described, in which the embossments 10a and the gloss-adjusting layer 15 are provided in harmony with the pattern of the pattern layer 12. However, the present invention is not limited to this. As another embodiment, for example, depending on the pattern of the pattern layer 12, it is also possible to use a decorative sheet and a decorative member using the same that omit the embossments 10a and the gloss-adjusting layer.

[0074] Furthermore, in the above-described embodiment, the decorative sheet 10 provided with the surface protective layer 14 and the decorative member 100 using the same have been described, but the present invention is not limited to this. As another embodiment, for example, depending on the conditions and environment in which it is used, it is also possible to use a decorative sheet and a decorative member using the same that omit the surface protective layer 14.

[0075] In the above-described embodiment, the decorative member (fitting) 100 is described in which the decorative sheet 10 is attached to a structural member (substrate) 101 such as a sash or door made of PVC resin, but the present invention is not limited to this. As another embodiment, for example, a decorative member in which the decorative sheet according to the present invention is attached to a substrate made of PVC resin can obtain the same effects as those of the above-described embodiment. [Example]

[0076] Examples of the decorative sheet and decorative member according to the present invention will be specifically described below, but the present invention is not limited to the following examples.

[0077] [Preparation of test specimens and comparison specimens] <Test piece 1> First, a transparent PVC resin (100 parts by mass) was mixed with a high molecular weight polyester plasticizer (25 parts by mass) and BASF Japan Ltd.'s triazine-based UVA "Tinuvin (registered trademark) 479" (0.5 parts by mass), and molded into a sheet to obtain a transparent raw layer (100 μm thick).

[0078] A pattern was then printed on the back side of the transparent base layer using a pattern ink made of a PVC resin binder resin, which was then dried and cured to form a pattern layer (1 μm thick). Subsequently, a colored concealing layer (1 μm thick) was formed by solid printing on the pattern layer using a concealing ink made of a PVC resin binder resin, which was then dried and cured. Subsequently, a liquid obtained by mixing the main agent and curing agent of a transparent resin material with a triazine UVA and HALS in a medium liquid in the following ratio was applied to the front side of the transparent base layer, which was then dried and cured to form a surface protection layer (dry solid content 3 g / m2 After providing a surface roughness (thickness: 3 μm), embossing was performed while heating with an embossing plate. In this way, decorative sheet specimen 1 was obtained in-line (single pass).

[0093] <Comparative body 5> Comparative specimen 5 of the decorative sheet and decorative member was produced under the same conditions as specimen 1, except that the transparent raw fabric layer was made of an acrylic resin.

[0094] The differences between these test specimens 1 to 9 and comparative specimens 1 to 5 are shown in Table 1 below.

[0095] [Table 1]

[0096] [Evaluation method] Productivity The surface quality of decorative sheet specimens 1 to 9 and comparative specimens 1 to 5 was visually inspected and evaluated for productivity (the occurrence of fisheyes, thickness unevenness, etc.). The results are shown in Table 2 below. In Table 2, "◎" indicates excellent productivity with almost no occurrence of fisheyes, thickness unevenness, etc. "○" indicates good productivity with slight occurrence of fisheyes, thickness unevenness, etc., but no practical problems. "△" indicates that by examining the conditions in more detail, it was possible to reduce fisheyes, thickness unevenness, etc. to a level that would not cause practical problems. "×" indicates that fisheyes, thickness unevenness, etc. occurred and the product was not practical. In this evaluation, "◎" and "○" were considered to be acceptable.

[0097] <Processability> For decorative member specimens 1 to 9 and the comparative specimen, the surface quality of the folded portion when the decorative sheet was wrapped was visually inspected to evaluate processability (presence or absence of whitening, cracks, etc.). The results are shown in Table 2 below. In Table 2, "◎" indicates excellent processability with almost no whitening or cracks. "○" indicates good processability with slight whitening or cracks, but no practical problems. "△" indicates that by further examining the conditions, it was possible to reduce whitening, cracks, etc. to a level that would not cause practical problems. "×" indicates that whitening, cracks, etc. occurred and the product was not practical. In this evaluation, "◎" and "○" were considered to be acceptable.

[0098] <Weather resistance> A weathering test was conducted for 504 hours on decorative component specimens 1 to 9 and comparative specimens 1 to 5 using an ultra-accelerated weathering tester (Daipla Wintes Co., Ltd.'s "Metal Weather (registered trademark) KU-R5DC1-A (product number)"), which consisted of 20 hours of UV light exposure and 4 hours of condensation, under the following conditions. The weathering resistance of specimens 1 to 9 and comparative specimens 1 to 5 was evaluated by determining the color difference ΔE on the front side before and after the test. The results are shown in Table 2 below. In Table 2, "◎" indicates that the color difference ΔE was less than 2 (ΔE<2). "○" indicates that the color difference ΔE was 2 or more but less than 4 (2≦ΔE<4). "△" indicates that some color differences ΔE were 4 or more (ΔE≧4). "×" indicates that the color difference ΔE was 4 or more (ΔE≧4) throughout the entire test. In this evaluation, "◎" and "○" were considered to be acceptable.

[0099] <Test conditions> ·UV light illuminance: 65mW / cm 2 Black panel temperature: 63°C

[0100] <Recyclability> The decorative member test specimens 1 to 9 and comparative specimens 1 to 5 were melted and extruded using an extruder to evaluate their recyclability as recycled materials. The results are shown in Table 2 below. In Table 2, "◎" indicates excellent recyclability, with smooth extrusion processing possible without any decorative sheet remaining. "○" indicates good recyclability, with extrusion processing possible without practical problems. "△" indicates that further detailed consideration of the conditions could potentially result in a level of practical problem-free recyclability. "×" indicates that extrusion processing was difficult and recyclability was poor. In this evaluation, "◎" and "○" were considered to be acceptable.

[0101] [Evaluation results] The evaluation results are shown in Table 2 below.

[0102] [Table 2]

[0103] As can be seen from Table 2, some of the comparative samples 1 to 5 were evaluated as "△". In contrast, all of the test samples 1 to 9 were evaluated as "○" or higher. Therefore, the effect of the present invention was confirmed. [Industrial Applicability]

[0104] The decorative sheets and decorative members of the present invention can be made thinner to conserve resources without reducing productivity or processability, and can therefore be used to great advantage in a variety of industries, including the construction industry.
