Description

Technical Field

[0001] The present disclosure relates to a decorative material and a method for manufacturing the decorative material.

Background Art

[0002] Decorative materials are used, for example, to decorate interior and exterior materials such as furniture, fixtures, and wall surfaces. Among decorative materials, there are those that have a plurality of grooves and are filled with ink inside the grooves in order to impart a predetermined texture. A decorative material filled with ink inside the grooves can be produced, for example, by undergoing a process of "spreading" or "wiping", which refers to the process of placing ink for a filling portion containing a coloring agent on the surface of the decorative material having grooves and then scraping the ink for the filling portion in a predetermined direction. In this specification, the above-described process may be referred to as "scraping" or "wiping". When ink for a filling portion containing a coloring agent is placed on the surface of the decorative material having grooves, a part of the grooves is filled with ink. Then, when scraping the ink, excess ink is removed and the ink can be pushed into a part of the grooves.

[0003] As decorative materials produced through scraping, for example, the decorative materials of Patent Documents 1 and 2 have been proposed.

Problems to be Solved by the Invention

[0005] In the decorative materials described in Patent Documents 1 and 2, ink sometimes failed to fill grooves extending perpendicular to the scraping direction. As a result, the areas where ink was not filled were noticeable, and the texture of the decorative materials described in Patent Documents 1 and 2 was unsatisfactory. Furthermore, depending on the design of the decorative material, the direction in which the grooves extend may be biased in a predetermined direction. Thus, in decorative materials where the direction of the grooves is biased in a predetermined direction, the aforementioned texture problem was serious.

[0006] This disclosure aims to provide a decorative material that can achieve a high ink filling rate in grooves.

Modes for Carrying Out the Invention

[0010] [Decorative Material (First Decorative Material)] The first decorative material included in the present disclosure has a base material layer and a surface protection layer, the base material layer has a plurality of grooves on the surface on the side of the surface protection layer, at least some of the grooves have a filling portion containing a coloring agent inside the groove, when grooves extending in a direction within a range of ±10 degrees with respect to a predetermined direction are defined as vertical grooves among the grooves, 60% or more of the number of the vertical grooves satisfies the following formula 1A. H≦-0.0425×W + 86 μm (Formula 1A) (In Equation 1A, "H" represents the groove depth and "W" represents the groove width. The units for "H" and "W" are "μm".)

[0011] Figure 1 is a cross-sectional view showing one embodiment of the decorative material 100 of the present disclosure. The decorative material 100 in Figure 1 has a base layer 10 and a surface protection layer 40. In Figure 1, the base layer 10 has a plurality of grooves 21 on the surface facing the surface protection layer 40. In Figure 1, at least some of the grooves 21 have a filler portion 22 containing a coloring agent inside the groove. In Figure 1, the base layer 10 is a multilayer base layer having a transparent resin layer 11, an adhesive layer 12, a decorative layer 13, and a colored base material 14 in that order. The decorative material 100 in Figure 1 has a primer layer 30 between the base layer 10 and the surface protection layer 40. Figures 1-5 are diagrams common to the first to third decorative materials.

[0012] <Base material layer> The base layer of the first decorative material must have a plurality of grooves on the surface facing the protective layer. At least some of the grooves must have a filler portion containing a coloring agent inside. When grooves extending in a direction within ±10 degrees perpendicular to a predetermined direction are defined as vertical grooves, at least 60% of the number of vertical grooves must satisfy the following formula 1A. H≦-0.0425×W+86μm (Formula 1A) (In Equation 1A, "H" represents the groove depth and "W" represents the groove width. The units for "H" and "W" are "μm".)

[0013] The first decorative material of this disclosure has a base layer having multiple grooves, and since the grooves satisfy the above formula 1A, the ink filling rate into the grooves can be increased. The technical significance of formula 1A will be explained below. First, the filling portion formed inside the groove has two directions: one in which the height is uneven, and another in which the height is uniform. In this specification, the direction in which the height of the filling portion is uneven is referred to as the "predetermined direction." Also, in this specification, the direction in which the height of the filling portion is uniform is referred to as the "direction perpendicular to the predetermined direction." "Height of the filling portion" refers to the position of the filling portion in the thickness direction of the decorative material. In other words, "height of the filling portion" may differ from the thickness of the filling portion. "Uneven filling height" means that the difference in filling height is 5 μm or more. If there are multiple directions in which the difference in filling height is 5 μm or more, the direction in which the difference in filling height per unit length is largest should be considered the direction in which "uneven filling height". In the direction in which "uniform filling height", it is preferable that the difference in filling height is less than 5 μm, and more preferably 3 μm or less.

[0014] Decorative materials exhibiting both uneven filling heights and uniform filling heights can be observed, for example, in decorative materials manufactured through scraping. That is, when a filling ink containing a coloring agent is placed on the grooved surface of a decorative material, and then the filling ink is scraped off in a predetermined direction, the filling height tends to be uneven in the scraping direction, while the filling height tends to be uniform in the direction perpendicular to the scraping direction. The above will be further explained using Figure 2. Consider the case where ink is placed on the surface of the decorative material in Figure 2(a) and the ink is scraped off in the Y-Y' direction. In this case, the Y-Y' direction, which is aligned with the scraping direction, tends to result in uneven filling heights, as shown in the cross-sectional view of Figure 2(b). On the other hand, the X-X' direction, which is perpendicular to the scraping direction, tends to result in uniform filling heights, as shown in the cross-sectional view of Figure 2(c). Therefore, in this disclosure, "a predetermined direction" can also be interpreted as meaning "the scraping direction." Furthermore, in this disclosure, "a direction perpendicular to the predetermined direction" can also be interpreted as meaning "a direction perpendicular to the scraping direction." Furthermore, among the grooves in the base material layer, those extending approximately perpendicular to the scraping direction are less likely to be filled with ink. This is because, during scraping, the ink is easily scraped out of these grooves. Therefore, in this disclosure, "grooves extending in a direction within a range of ±10 degrees perpendicular to a predetermined direction" can be said to specify "grooves that are less likely to be filled with ink during scraping (≒ grooves extending at ±10 degrees perpendicular to the scraping direction)." In other words, formula 1A specifies that for more than 60% of grooves where ink is difficult to fill during scraping, the groove depth and groove width must exhibit a predetermined relationship.

[0015] The inventors investigated what kind of grooves, extending at ±10 degrees perpendicular to a predetermined direction, would be easily filled with ink during scraping. As a result, they found that even grooves extending at ±10 degrees perpendicular to a predetermined direction, as long as they satisfy formula 1A, are easily filled with ink, thereby forming a filled portion. Figure 3 plots grooves extending at ±10 degrees perpendicular to a given direction, with grooves having a filled portion marked with "●" and grooves without a filled portion marked with "×". In Figure 3, the horizontal axis represents the groove width "W [μm]", and the vertical axis represents the groove depth "H [μm]". The dashed line in Figure 3 represents "H = -0.0425 × W + 86 μm". Figure 3 shows that in regions satisfying "H ≤ -0.0425 × W + 86 μm", the proportion of grooves with filled areas is high, while in regions not satisfying "H ≤ -0.0425 × W + 86 μm", the proportion of grooves with filled areas is low. In the example in Figure 3, in regions satisfying "H ≤ -0.0425 × W + 86 μm", approximately 85% of the grooves have filled areas. From this result, it can be confirmed that even grooves that are difficult to fill with ink during scraping (≒ grooves extending at ±10 degrees perpendicular to the scraping direction) can easily form filled areas if they satisfy Equation 1A. The first decorative material of this disclosure specifies that 60% or more of the number of vertical grooves satisfy formula 1A. Therefore, the first decorative material of this disclosure can form fillers in at least about half of the number of vertical grooves (60% × 85% = 51%).

[0016] The proportion of the vertical grooves that satisfy formula 1A is preferably 70% or more, more preferably 80% or more, more preferably 90% or more, more preferably 95% or more, and most preferably 100%, based on the number of grooves. By satisfying the above proportion, the proportion of the vertical grooves in which a filling portion is formed can be increased.

[0017] In Figure 3, "grooves with a filled portion" and "grooves without a filled portion" were distinguished as follows. The grooves were observed visually and with a laser microscope. Grooves where the area of ​​filler was present in proportion to the total groove area was 50% or more were classified as "grooves with filler," and grooves where the area of ​​filler was present in proportion to the total groove area was less than 50% were classified as "grooves without filler." A Keyence VK-X1000 laser microscope was used.

[0018] Furthermore, regarding grooves other than those in the vertical direction, a filling portion is easily formed within the groove regardless of Equation 1A. For this reason, if all grooves are in directions other than the vertical direction, it is thought that the problem of filling rate will not occur. However, if all grooves are in directions other than the vertical direction, the degree of design freedom will be lacking, and furthermore, an unnatural feeling will arise due to the absence of grooves in a specific direction, making it difficult to obtain a decorative material with a high texture.

[0019] <<Groove shape, etc.>> The grooves in the base layer are not particularly limited in shape, etc., as long as they satisfy formula 1A. Embodiments of the grooves will be described below.

[0020] The planar shape of the groove is not particularly limited, and various patterns can be used. When the design expressed by the entire decorative material is a wood grain pattern, it is preferable that the planar shape of the grooves form one or more patterns selected from burnt cedar cracks, vessels, autumn wood, and knots. "Burnt cedar cracks" refers to cracks that are formed perpendicular to the grain direction when the surface of a cedar board is charred to form a carbon layer. When the overall design of the decorative material is a stone pattern such as travertine, it is preferable that the groove's shape in plan view be a recessed area. Figure 4 shows one embodiment of the plan view shape of the groove 21 in the base layer 10.

[0021] The direction D1, which represents the direction in which each groove extends, is the average direction of the individual grooves. Furthermore, the direction in which each groove extends represents the direction in which the distance between any two points within that groove is maximized. For example, in the case of the groove in Figure 5, the direction D1 is the direction connecting points A and B. The length of each groove represents the length that maximizes the distance between any two points within that groove. In the case of the groove in Figure 5, the distance between point A and point B is the length of the groove.

[0022] The groove width is not particularly limited, but is preferably 30 μm to 1000 μm, more preferably 50 μm to 900 μm, and even more preferably 80 μm to 800 μm. With respect to individual grooves, the groove depth is not limited, but is preferably 10 μm or more and 100 μm or less, more preferably 20 μm or more and 95 μm or less, and even more preferably 30 μm or more and 90 μm or less. With respect to individual grooves, the length of the groove is not limited, but is preferably between 1 mm and 100 mm, more preferably between 2 mm and 80 mm, and even more preferably between 3 mm and 50 mm.

[0023] The depth of each groove can be calculated, for example, in steps A1 to A2 below. A1: For each groove, height data in the direction transverse to the groove is measured at five randomly selected locations, and five cross-sectional curves with height data are obtained. If the plan view shape of the groove is an elongated shape extending in an arbitrary direction, the height data is measured in a direction perpendicular to D1, which is the direction in which the groove extends. For example, if the plan view shape of the groove is as shown in Figure 5, height data is measured at five locations a to e in the direction of the dotted line, which is perpendicular to the extension direction D1 of the groove. From the height data measured in A2:A1, the maximum depth at each measurement point is extracted, and the average of the five maximum depths is taken as the average depth of each groove.

[0024] The width of each groove can be calculated, for example, using B1 below. B1: Calculate the width of the groove at each measurement point from the five cross-sectional curves measured in A1 above. Then, take the average of the widths at the five points and use that as the width of each individual groove.

[0025] Of all the grooves present in the substrate layer, the proportion of grooves extending in a direction perpendicular to a predetermined direction within a range of ±40 degrees is preferably 80% or more, more preferably 90% or more, even more preferably 97% or more, and most preferably 100%, based on the number of grooves, in order to further enhance the texture. The fact that the direction of the grooves in the base layer is as described above means that the direction in which the grooves extend is biased in a predetermined direction. Thus, the first decorative material of this disclosure is preferable in that it is easy to achieve a good texture even when the direction of the grooves is biased in a predetermined direction.

[0026] When a predetermined direction is used as a reference, the standard deviation σ of the direction of all grooves present in the base layer is preferably between 1 degree and 20 degrees, more preferably between 2 degrees and 15 degrees, and even more preferably between 3 degrees and 10 degrees. By setting the standard deviation σ of the groove direction within the above range, the texture can be further enhanced, and it becomes easier to impart the appearance of natural materials. The ratio of the area where grooves are formed to the total area of ​​the base material layer is preferably 50% to 95%, more preferably 60% to 90%, and even more preferably 70% to 80%.

[0027] <<Method for forming grooves>> Grooves in the substrate layer can be formed, for example, by molding with an embossing plate. The embossing plate can be manufactured, for example, by engraving a metal roll with a laser beam. A method for engraving metal rolls with laser light is described, for example, in international publication number WO2020 / 203737.

[0028] The temperature and pressure used when forming with an embossing plate should be adjusted as appropriate depending on the material of the base layer. If the base material and transparent resin layer of the base layer are polyolefin, the temperature should be between 140°C and 180°C, and the pressure should be 10 kg / cm². 2 More than 50kg / cm 2 The following applies: Typical methods of patterning using embossing plates include the following: First, the embossing plate is pressed onto the softened base layer to create the pattern on the surface of the embossing plate. Then, the base layer is solidified by cooling or other means to fix the pattern formed on the base layer. After that, the base layer with the pattern formed on it is released from the embossing plate.

[0029] <<Layer structure of the base material layer>> The base layer may be a single layer or a multilayer structure with multiple layers stacked together. Examples of the layer configurations of the base layer include (1) to (10) below. In (1) to (10) below, " / " indicates the interface between layers. In the base layers of (1) to (10) below, it is preferable to arrange the layers listed on the left toward the surface protective layer. (1) Single layer of substrate (2) Decorative layer / base material (3) Substrate / Decorative layer (4) Transparent resin layer / base material (5) Transparent resin layer / decorative layer / substrate (6) Transparent resin layer / substrate / decorative layer (7) Transparent resin layer / adhesive layer / base material (8) Transparent resin layer / adhesive layer / decorative layer / substrate (9) Transparent resin layer / decorative layer / adhesive layer / substrate (10) Transparent resin layer / adhesive layer / substrate / decorative layer

[0030] -Base material- The material of the base material is not particularly limited, but a plastic film or a composite of a plastic film and paper is preferred due to the ease with which grooves can be formed by embossing or other processes.

[0031] Specific examples of resins that make up plastic films include polyolefin resins such as polyethylene and polypropylene, vinyl resins such as vinyl chloride resin, vinylidene chloride resin, polyvinyl alcohol, and ethylene-vinyl alcohol copolymer, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, acrylic resins such as polymethyl methacrylate, polymethyl acrylate, and polyethyl methacrylate, polystyrene, acrylonitrile-butadiene-styrene copolymer (ABS resin), cellulose triacetate, and polycarbonate. Among these, polyolefin resins, vinyl chloride resins, polyester resins, and acrylic resins are preferred because they have excellent printability and moldability.

[0032] The base material may be a transparent base material or a colored base material. Furthermore, the base material may be a laminated base material formed by stacking multiple base materials. In the case of the layer configuration of the base material layer as described in (6) and (10) above, it is preferable to use a transparent base material in order to allow the decorative layer to be visible through the base material.

[0033] There are no particular restrictions on the thickness of the substrate, but it is preferably 20 μm to 200 μm, more preferably 40 μm to 160 μm, and even more preferably 40 μm to 100 μm.

[0034] To improve adhesion with the layer provided on the substrate, one or both sides of the substrate may be treated with an easy-adhesion treatment such as a physical treatment or a chemical surface treatment.

[0035] —Decorative layer— The base layer may have a decorative layer to improve the aesthetic appeal of the decorative material. The decorative layer may be, for example, a colored layer that covers the entire surface (a so-called solid colored layer), a patterned layer with various designs, or a combination of these.

[0036] The patterns that can be added by the decorative layer are not particularly limited, but examples include wood grain patterns, stone grain patterns, etc. By forming these patterns with the decorative layer, the texture based on the grooves and filler areas can be further emphasized.

[0037] The decorative layer can be formed, for example, by applying and drying a decorative layer ink containing a coloring agent such as a pigment or dye and a binder resin. The decorative layer ink may optionally contain additives such as extender pigments, antioxidants, plasticizers, catalysts, curing agents, UV absorbers, and light stabilizers. The colorants and binder resins for the decorative layer are not particularly limited, and the same as those exemplified in the ink for the filling section described later can be used.

[0038] The thickness of the decorative layer is preferably 0.1 μm to 20 μm, more preferably 0.5 μm to 10 μm, and even more preferably 1.0 μm to 5.0 μm.

[0039] -Transparent resin layer- The base layer may have a transparent resin layer to increase its strength. Examples of resins that make up the transparent resin layer include polyolefin resins, polyester resins, polycarbonate resins, acrylonitrile-butadiene-styrene copolymers (ABS resins), acrylic resins, and vinyl chloride resins. Among these, polyolefin resins are preferred from the viewpoint of processability. Furthermore, the transparent resin layer may be a mixture of these example resins, or it may be a laminate of layers consisting of one or more of these example resins.

[0040] Examples of polyolefin resins for the transparent resin layer include polyethylene (low density, medium density, high density), polypropylene, polymethylpentene, polybutene, ethylene-propylene copolymer, propylene-butene copolymer, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, and ethylene-propylene-butene copolymer. Among these, polyethylene (low density, medium density, high density), polypropylene, ethylene-propylene copolymer, and propylene-butene copolymer are preferred, with polypropylene being more preferred.

[0041] The transparent resin layer may contain additives such as UV absorbers, light stabilizers, and colorants. If the transparent resin layer contains a UV absorber, the UV absorber is preferably a triazine compound, and more preferably a hydroxyphenyltriazine compound.

[0042] The thickness of the transparent resin layer is preferably 20 μm to 150 μm, more preferably 40 μm to 120 μm, and even more preferably 60 μm to 100 μm, from the viewpoint of balancing scratch resistance, processability, and weather resistance.

[0043] -Adhesive layer- The substrate layer may have an adhesive layer to improve interlayer adhesion. The adhesive layer can be made from a general-purpose adhesive such as a urethane-based adhesive, acrylic-based adhesive, epoxy-based adhesive, or rubber-based adhesive. Among these adhesives, a urethane-based adhesive is preferred in terms of adhesive strength. Examples of urethane-based adhesives include adhesives that utilize a two-component curing urethane resin containing various polyol compounds such as polyether polyols, polyester polyols, and acrylic polyols, and a curing agent such as an isocyanate compound.

[0044] The thickness of the adhesive layer is preferably 0.1 μm to 30 μm, more preferably 1 μm to 15 μm, and even more preferably 2 μm to 10 μm.

[0045] The shape of the surface of the substrate layer opposite to the surface protective layer is not particularly limited; it may be smooth or grooved.

[0046] <Filling section> At least some of the grooves must have a filler portion containing a coloring agent inside the groove. Having a filler portion inside the groove can enhance the texture of the decorative material.

[0047] The proportion of grooves with a filled portion is preferably 90% or more, and more preferably 95% or more, based on the number of grooves.

[0048] One method for forming a filler portion containing a coloring agent in a groove is to apply a filler ink containing a coloring agent and a binder resin to the grooved side of the base layer, and then scrape off the ink with a scraping blade such as a doctor blade. In this case, the amount of coloring agent filled into the groove can be adjusted by adjusting the material of the blade and the angle at which the blade is applied. To make it easier to push the ink into the groove, it is preferable that the blade be made of a soft material. Similarly, to make it easier to push the ink into the groove, it is preferable to tilt the blade relative to the base layer toward the direction of travel of the base layer.

[0049] Examples of colorants include inorganic pigments such as carbon black (ink), iron black, titanium white, antimony white, lead yellow, titanium yellow, red iron oxide, cadmium red, ultramarine, and cobalt blue; organic pigments such as quinacridone red, isoindolinone yellow, and phthalocyanine blue; and dyes. The coloring agent content is preferably 1 part by mass or more and 90 parts by mass or less, and more preferably 2 parts by mass or more and 50 parts by mass or less, per 100 parts by mass of binder resin.

[0050] The color of the coloring agent is not particularly limited, but dark coloring agents are preferred. Dark coloring agents can darken the grooves, thereby increasing the contrast in brightness within the surface of the decorative material. Dark colors refer to low-brightness, low-chroma colors that give a dark impression, such as dark gray, dark green, navy blue, black, dark purple, maroon, and brown.

[0051] Examples of binder resins include acrylic resins, styrene resins, polyester resins, urethane resins, chlorinated polyolefin resins, vinyl chloride-vinyl acetate copolymers, polyvinyl butyral, alkyd resins, petroleum-based resins, ketone resins, epoxy resins, melamine resins, fluororesins, silicone resins, and rubber-based resins.

[0052] The filling portion may contain a matting agent to further enhance the texture. When the filling portion contains a matting agent, the difference between grooves with the filling portion and grooves without the filling portion becomes more noticeable, which can easily lead to a decrease in texture. The decorative material of this disclosure allows for a higher proportion of grooves with the filling portion, making it easier to suppress the aforementioned decrease in texture.

[0053] Examples of matting agents include inorganic particles such as silica, calcium carbonate, titanium dioxide, and barium sulfate; and organic particles such as acrylic beads and styrene beads. The average particle size of the matting agent is preferably 1 μm or more and 20 μm or less. In this specification, the average particle size refers to the mass-average value d50 obtained by particle size distribution measurement using laser diffraction. The matting agent content is preferably 1 to 30 parts by mass, and more preferably 2 to 20 parts by mass, per 100 parts by mass of binder resin.

[0054] The filling portion preferably contains at least one of an ultraviolet absorber and a light stabilizer. The decorative material of this disclosure allows for a high proportion of grooves having filling portions, and by including weather-resistant agents such as ultraviolet absorbers and light stabilizers in the filling portions, the weather resistance of the decorative material can be easily improved.

[0055] Examples of UV absorbers include inorganic UV absorbers and organic UV absorbers. As inorganic ultraviolet absorbers, titanium dioxide, cerium oxide, zinc oxide, etc., with an average particle size of 5 nm to 120 nm, can be preferably used. Examples of organic UV absorbers include benzotriazole compounds, triazine compounds, and benzophenone compounds. The amount of ultraviolet absorber is preferably 1 part by mass or more and 50 parts by mass or less, and more preferably 10 parts by mass or more and 40 parts by mass or less, per 100 parts by mass of binder resin. Examples of light stabilizers include hindered amine-based light stabilizers. The content of the light stabilizer is preferably 1 to 50 parts by mass, and more preferably 10 to 40 parts by mass, per 100 parts by mass of the binder resin.

[0056] <Surface protective layer> The decorative material has a surface protective layer. The surface protective layer preferably contains a cured product of a curable resin composition in order to improve the scratch resistance of the decorative material.

[0057] Examples of curable resin compositions include thermosetting resin compositions containing thermosetting resins, ionizing radiation-curable resin compositions containing ionizing radiation-curable resins, and mixtures thereof. Among these, ionizing radiation-curable resin compositions are preferred because they increase the crosslinking density of the surface protective layer and improve surface properties such as scratch resistance. Furthermore, electron beam-curable resin compositions are more preferred among ionizing radiation-curable resin compositions because they can be applied without solvents and are easy to handle.

Examples of thermosetting resins include acrylic resins, urethane resins, phenolic resins, urea-melamine resins, epoxy resins, unsaturated polyester resins, and silicone resins. A curing agent is added to these curable resins as needed in the thermosetting resin composition.

[0059] An ionizing radiation-curable resin composition is a composition containing a compound having an ionizing radiation-curable functional group (hereinafter also referred to as "ionizing radiation-curable compound"). The ionizing radiation-curable functional group is a group that crosslinks and hardens upon irradiation with ionizing radiation, and preferred examples include functional groups having an ethylenically double bond, such as a (meth)acryloyl group, a vinyl group, or an allyl group. In this specification, a (meth)acryloyl group refers to an acryloyl group or a metacloyl group. In this specification, a (meth)acrylate refers to an acrylate or a methacrylate. Ionizing radiation refers to electromagnetic waves or charged particle beams that have energy quanta capable of polymerizing or bridging molecules. While ultraviolet (UV) or electron beams (EB) are commonly used, the term also includes other electromagnetic waves such as X-rays and gamma rays, as well as charged particle beams such as alpha rays and ion beams. Specifically, the ionizing radiation-curable compound can be appropriately selected from polymerizable monomers and polymerizable oligomers that have been conventionally used as ionizing radiation-curable resins.

[0060] As polymerizable monomers, (meth)acrylate monomers having a radical polymerizable unsaturated group in the molecule are preferred, and among these, polyfunctional (meth)acrylate monomers are preferred. Here, "(meth)acrylate" means "acrylate or methacrylate". Examples of polyfunctional (meth)acrylate monomers include (meth)acrylate monomers having two or more ionizing radiation-curable functional groups in the molecule, and having at least one (meth)acryloyl group as such functional group.

[0061] Examples of polymerizable oligomers include (meth)acrylate oligomers having two or more ionizing radiation-curable functional groups in the molecule, and having at least one (meth)acryloyl group as such functional group. Examples include urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers, polyester (meth)acrylate oligomers, polyether (meth)acrylate oligomers, polycarbonate (meth)acrylate oligomers, acrylic (meth)acrylate oligomers, and the like. Furthermore, polymerizable oligomers include other highly hydrophobic polybutadiene (meth)acrylate oligomers having (meth)acrylate groups in the side chains of polybutadiene oligomers, silicone (meth)acrylate oligomers having polysiloxane bonds in the main chain, aminoplast resin (meth)acrylate oligomers obtained by modifying aminoplast resins that have many reactive groups in a small molecule, or oligomers having cationic polymerizable functional groups in the molecules of novolac-type epoxy resins, bisphenol-type epoxy resins, aliphatic vinyl ethers, aromatic vinyl ethers, etc.

[0062] These polymerizable oligomers may be used individually or in combination of multiple types. From the viewpoint of improving processing characteristics, scratch resistance, and weather resistance, one or more selected from urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers, polyester (meth)acrylate oligomers, polyether (meth)acrylate oligomers, polycarbonate (meth)acrylate oligomers, and acrylic (meth)acrylate oligomers are preferred, one or more selected from urethane (meth)acrylate oligomers and polycarbonate (meth)acrylate oligomers are more preferred, and urethane (meth)acrylate oligomers are even more preferred.

[0063] Monofunctional (meth)acrylates may be used in combination with ionizing radiation-curable resin compositions for purposes such as reducing the viscosity of the ionizing radiation-curable resin composition. These monofunctional (meth)acrylates may be used individually or in combination of multiple types.

[0064] When the ionizing radiation-curable compound is an ultraviolet-curable compound, the ionizing radiation-curable resin composition preferably contains additives such as photopolymerization initiators and photopolymerization accelerators. Examples of photopolymerization initiators include one or more selected from acetophenone, benzophenone, α-hydroxyalkylphenone, Michler ketone, benzoin, benzyldimethyl ketal, benzoylbenzoate, α-acyloxime ester, thioxanthones, etc. Furthermore, photopolymerization accelerators can reduce polymerization inhibition by air during curing and accelerate the curing speed.

[0067] <Primer layer> A primer layer may be provided between the substrate layer and the surface protective layer to improve adhesion. The primer layer is mainly composed of a binder resin. The primer layer may also contain additives such as UV absorbers and light stabilizers.

These can be used individually or in combination. The binder resin may also be obtained by adding a curing agent such as an isocyanate-based curing agent or an epoxy-based curing agent to these resins and crosslinking and curing them. Among these, polyol-based resins such as acrylic polyol resins crosslinked and cured with an isocyanate-based curing agent are preferred, and acrylic polyol resins crosslinked and cured with an isocyanate-based curing agent are more preferred.

[0069] The thickness of the primer layer is preferably 0.5 μm to 10 μm, more preferably 0.7 μm to 8 μm, and even more preferably 1 μm to 6 μm.

[0070] <Primer layer on the back surface> The decorative material of this disclosure may have a backside primer layer on the side opposite to the surface protective layer of the base layer in order to improve the adhesion between the decorative material and various adherends.

The thickness of the primer layer on the back surface is preferably 0.5 μm or more and 5.0 μm or less, and more preferably 1 μm or more and 3 μm or less.

[0071] The surface protective layer, decorative layer, primer layer, adhesive layer, and backside primer layer can be formed by applying an ink containing the composition for each layer using a known method such as gravure printing, bar coating, roll coating, reverse roll coating, or comma coating, and then drying and curing it as necessary. The transparent resin layer can be formed, for example, by hot melt extrusion.

[0072] [Decorative material (second decorative material)] The second decorative material included in this disclosure is A decorative material having a base layer and a surface protective layer, The aforementioned decorative material has a rectangular shape in plan view, with a longitudinal direction and a transverse direction. The substrate layer has a plurality of grooves on the surface facing the surface protection layer, At least some of the grooves have a filling portion containing a coloring agent inside the groove, When, among the grooves mentioned above, the grooves extending in the range of ±10 degrees from the longitudinal direction are defined as longitudinal grooves, At least 60% of the aforementioned longitudinal grooves satisfy the following formula 1B. H≦-0.0425×W+86μm (Formula 1B) (In Equation 1B, "H" represents the groove depth and "W" represents the groove width. The units for "H" and "W" are "μm".)

[0073] <Base material layer> The base layer of the second decorative material must have a plurality of grooves on the surface facing the protective layer. At least some of the grooves must have a filler portion containing a coloring agent inside. When grooves extending in a range of ±10 degrees from the longitudinal direction are defined as longitudinal grooves, at least 60% of the number of longitudinal grooves must satisfy the following formula 1B. H≦-0.0425×W+86μm (Formula 1B) (In Equation 1B, "H" represents the groove depth and "W" represents the groove width. The units for "H" and "W" are "μm".)

[0074] The second decorative material of this disclosure has a base layer having multiple grooves, and since the grooves satisfy the above formula 1B, the ink filling rate into the grooves can be increased. The technical significance of formula 1B will be explained below. In decorative materials whose plan view shape is a rectangle with a longitudinal and transverse direction, it is preferable to direct the grooves so that they extend within a predetermined angle relative to the longitudinal direction in order to emphasize the texture. On the other hand, for manufacturing reasons, when filling the grooves of the aforementioned decorative material with a plan view shape with ink containing a coloring agent, the direction in which the ink is scraped off may be perpendicular to the longitudinal direction. As explained with the first decorative material, grooves in the base layer that extend approximately perpendicular to the scraping direction are difficult to fill with ink. In other words, formula 1B specifies that, when the ink scraping direction is perpendicular to the longitudinal direction, at least 60% of the grooves that are difficult to fill with ink will have a predetermined relationship between groove depth and groove width. The inventors have found a longitudinal Direction ± Regarding grooves extending at a 10-degree angle, we investigated what kind of grooves would allow ink to be easily filled during scraping. As a result, the longitudinal Direction± We found that even grooves extending at a 10-degree angle can easily form a filled area if they satisfy Equation 1B. The effect of satisfying Equation 1B can be explained in Figure 3. Figure 3 is as explained for the first decorative material.

[0075] The proportion of longitudinal grooves that satisfy formula 1B is preferably 70% or more, more preferably 80% or more, more preferably 90% or more, more preferably 95% or more, and most preferably 100%, based on the number of grooves. By satisfying the above proportion, the proportion of longitudinal grooves in which a filling portion is formed can be increased.

[0076] Furthermore, when the ink scraping direction is perpendicular to the longitudinal direction, a filling portion is easily formed in grooves other than those in the longitudinal direction, regardless of Equation 1B. For this reason, if all grooves are in directions other than the longitudinal direction, it is thought that the problem of filling rate will not occur. However, if all grooves are in directions other than the longitudinal direction, the degree of design freedom is lacking, and furthermore, an unnatural feeling arises due to the absence of grooves in a specific direction, making it difficult to obtain a decorative material with a high texture.

[0077] <<Groove shape, etc.>> The shape of the groove in the second decorative material is not particularly limited, as long as it satisfies formula 1B. Unless otherwise specified, embodiments of the groove in the second decorative material are the same as embodiments of the groove in the first decorative material.

[0078] Of all the grooves present in the substrate layer, the longitudinal direction Direction ± The proportion of grooves extending in a 40-degree range is preferably 80% or more, more preferably 90% or more, even more preferably 97% or more, and most preferably 100%, based on the number of grooves, in order to further enhance the texture. The fact that the direction of the grooves in the base layer is as described above means that the direction in which the grooves extend is biased towards the longitudinal direction. Thus, the second decorative material of this disclosure is preferable in that it is easy to achieve a good texture even when the direction of the grooves is biased towards the longitudinal direction.

[0079] When the longitudinal direction is used as a reference, the standard deviation σ of the direction of all grooves present in the base layer is preferably between 1 degree and 20 degrees, more preferably between 2 degrees and 15 degrees, and even more preferably between 3 degrees and 10 degrees. By setting the standard deviation σ of the groove direction within the above range, the texture can be further enhanced, and it becomes easier to impart the appearance of natural materials.

[0080] With respect to the second decorative material of this disclosure, the groove formation method, filling portion, layer structure of the base material layer, surface protective layer, decorative layer, transparent resin layer, primer layer and back surface primer layer are the same as those of the first decorative material unless otherwise specified.

[0081] [Decorative material (third decorative material)] The third decorative material included in this disclosure is A decorative material having a base layer and a surface protective layer, The aforementioned decorative material is in roll form, The substrate layer has a plurality of grooves on the surface facing the surface protection layer, At least some of the grooves have a filling portion containing a coloring agent inside the groove, When, among the grooves mentioned above, grooves extending in a direction within ±10 degrees of the width direction of the roll of the decorative material are defined as grooves in the width direction, At least 60% of the grooves in the width direction satisfy the following formula 1C. H≦-0.0425×W+86μm (Formula 1C) (In Equation 1C, "H" represents the groove depth and "W" represents the groove width. The units for "H" and "W" are "μm".)

[0082] The third decorative material of this disclosure has a base layer having multiple grooves, and since the grooves satisfy the above formula 1C, the ink filling rate into the grooves can be increased. The technical significance of formula 1C will be explained below. The rolled decorative material is made of decorative layers pattern In some cases, a pattern may be formed. The pattern of a roll-shaped decorative material is usually formed so that the pattern continues in the direction of the length of the roll. The direction of the length of the roll is perpendicular to the direction of the width of the roll. Also, the direction of the length of the roll is the direction in which the roll is moved during the manufacturing process of the decorative material. For this reason, in roll-shaped decorative materials, in order to emphasize the texture by distinguishing it from the direction of the pattern, it is preferable that the direction in which the grooves extend be within a predetermined angle relative to the width of the roll. On the other hand, when filling the grooves of a roll-shaped decorative material with ink containing a coloring agent, for reasons related to the manufacturing process, the direction in which the ink is scraped off is perpendicular to the width of the roll. As explained with the first decorative material, grooves in the base layer that extend approximately perpendicular to the scraping direction are difficult to fill with ink. In other words, in formula 1C, the width is difficult to fill with ink. Direction ±The regulations stipulate that for more than 60% of grooves extending at a 10-degree angle, the groove depth and groove width must exhibit a predetermined relationship. The inventors of this invention have found that the width of Direction± Regarding grooves extending at a 10-degree angle, we investigated what kind of grooves would allow ink to be easily filled during scraping. As a result, the width... Direction± We found that even grooves extending at a 10-degree angle can easily form a filled area if they satisfy Equation 1C. The effect of satisfying Equation 1C can be explained in Figure 3. Figure 3 is as explained for the first decorative material.

[0083] The proportion of grooves in the width direction that satisfy formula 1C is preferably 70% or more, more preferably 80% or more, more preferably 90% or more, more preferably 95% or more, and most preferably 100%, based on the number of grooves. By satisfying the above proportion, the proportion of grooves in the width direction that are filled can be increased.

[0084] Furthermore, regarding grooves in directions other than the width direction, a filling portion is easily formed within the groove regardless of Equation 1C. For this reason, if all grooves are in directions other than the width direction, it is thought that the problem of filling rate will not occur. However, if all grooves are in directions other than the width direction, the degree of design freedom will be lacking, and furthermore, an unnatural feeling will arise due to the absence of grooves in a specific direction, making it difficult to obtain a decorative material with a high texture.

[0085] <<Groove shape, etc.>> The groove of the third decorative material is not particularly limited in shape, etc., as long as it satisfies formula 1C. Unless otherwise specified, embodiments of the groove of the third decorative material are the same as embodiments of the groove of the first decorative material.

[0086] Of all the grooves present in the substrate layer, the width Direction± The proportion of grooves extending in a 40-degree range is preferably 80% or more, more preferably 90% or more, even more preferably 97% or more, and most preferably 100%, based on the number of grooves, in order to further enhance the texture. The fact that the groove direction of the base layer is as described above means that the direction in which the grooves extend is biased towards the width direction. Thus, the third decorative material of this disclosure is preferable in that it is easy to achieve a good texture even when the groove direction is biased towards the width direction.

[0087] When the width direction is used as the reference, the standard deviation σ of the direction of all grooves present in the base layer is preferably between 1 degree and 20 degrees, more preferably between 2 degrees and 15 degrees, and even more preferably between 3 degrees and 10 degrees. By setting the standard deviation σ of the groove direction within the above range, the texture can be further enhanced, and it becomes easier to impart the appearance of natural materials.

[0088] With respect to the third decorative material of this disclosure, the groove formation method, filling portion, layer structure of the base material layer, surface protective layer, decorative layer, transparent resin layer, primer layer and back surface primer layer are the same as those of the first decorative material unless otherwise specified.

[0089] <Uses of decorative materials> The decorative material disclosed herein can be used as is or as a laminate bonded to a substrate for various applications. Various applications include interior materials for buildings such as walls, ceilings, and floors; building fixtures such as window frames, doors, and handrails; furniture; casings for home appliances and office equipment; and exterior materials such as entrance doors. Examples of substrates include wood-based boards, gypsum-based boards, cement boards, fiber cement boards, ceramic boards, iron plates, metal plates, resin plates, and FRP boards.

[0090] [Method of manufacturing decorative materials] The method for manufacturing the cosmetic material described herein includes the following steps 1 to 4. Step 1: A step in which the base material layer is molded with an embossing plate to form multiple grooves. In Step 1, when grooves extending in a direction within ±10 degrees perpendicular to the scraping direction of Step 3 are defined as vertical grooves, at least 60% of the number of vertical grooves satisfy the following formula 1D. H≦-0.0425×W+86μm (Formula 1D) (In Equation 1D, "H" represents the groove depth and "W" represents the groove width. The units for "H" and "W" are "μm".) Step 2: Applying a filler ink containing a coloring agent to the side of the base layer that has been molded with an embossing plate. Step 3: A step of scraping off ink for the filling portion in a predetermined direction, and forming a filling portion containing a coloring agent inside at least some of the grooves. Step 4: A step to form a surface protective layer on the side of the base material layer that has been molded with an embossing plate.

[0091] <Process 1> Step 1 is the process of forming multiple grooves by shaping the base layer with an embossing plate. In step 1, grooves are formed such that at least 60% of the grooves extending in a direction within ±10 degrees perpendicular to the scraping direction of step 3 satisfy equation 1D.

[0092] The width and depth of the grooves are generally determined by the shape of the embossing plate. For this reason, it is preferable that the embossing plate has a textured surface such that the molded base layer satisfies formula 1D. To facilitate control of the textured surface of the embossing plate, it is preferable to manufacture the embossing plate by engraving a metal roll with laser light.

[0093] The embossing conditions in step 1 are not particularly limited. Examples of embossing conditions include a temperature of 140°C to 180°C and a pressure of 10 kg / cm². 2 More than 50kg / cm 2 The following are listed below.

[0094] <Process 2> Step 2 is the process of applying a filling ink containing a coloring agent to the side of the base layer that has been molded with an embossing plate. In step 2, some of the grooves are filled with ink. The ink for the filling section preferably contains a binder resin and a solvent in addition to a colorant.

[0095] <Process 3> Step 3 is a step of scraping off the ink for the filling portion in a predetermined direction and forming a filling portion containing a coloring agent inside at least some of the grooves. Step 3, the scraping process, removes excess ink and also pushes some of the ink into the grooves.

[0096] As a means of scraping off the ink, it is preferable to use a scraping blade such as a doctor blade. The angle of the blade relative to the substrate layer is preferably 3 to 45 degrees, more preferably 5 to 30 degrees, with respect to the direction perpendicular to the substrate layer. A positive value indicates an angle toward the direction of travel of the substrate layer, while a negative value indicates an angle toward the opposite direction of travel of the substrate layer. The blade material can be metal, rubber, or resin, with metal being preferred among these. The pressure applied to the substrate layer by the blade can be adjusted as appropriate, within a range that does not cause streaks or unevenness in the ink.

[0097] In step 3, it is preferable to place a roll with a circular cross-section on the side opposite to the side where the blade for scraping the base material layer is located. Examples of materials for the roll include metal, rubber, and resin.

[0098] It is preferable to have a step of curing the binder resin of the ink for the filling part during step 3, or after the completion of step 3 and before the start of step 4.

[0099] <Step 4> Step 4 is the process of forming a surface protective layer on the side of the base material layer that has been molded with the embossing plate. The surface protective layer can be formed, for example, by applying an ink containing the components that make up the surface protective layer using a general-purpose coating means to form a coating film, and then drying and curing the coating film as needed.

[0100] If a primer layer is present between the substrate layer and the surface protective layer, it is preferable to form the primer layer between step 3 and step 4. [Explanation of symbols]
