Description

  The present invention relates to a decorative material for use in surface makeup of buildings and the like, interior and exterior of buildings, furniture and the like. More specifically, the present invention relates to a decorative material that expresses unevenness three-dimensionally by the difference in surface gloss.

  When expressing uneven shapes in decorative materials that have been used for knockdown assembly furniture, residential building materials, furniture, etc., instead of actually forming them on the surface of the decorative material, the surface of the part you want to express as a concave or convex part There is a technique for visually expressing a three-dimensional impression of unevenness using the illusion of human eyes by making the glossy states different from each other. According to this method, even if there is no actual uneven shape, a portion with relatively high gloss is recognized as a convex portion and a portion with low gloss is recognized as a concave portion to human eyes.

  Specifically, for example, the above-described method is performed by forming a transparent or translucent synthetic resin coating layer having a low gloss on the entire printed surface of a substrate on which an appropriate pattern including a dent pattern is printed, and then performing the synthesis. A glossy transparent or translucent synthetic resin coating layer is formed on a portion of the surface of the resin material layer excluding a portion corresponding to the dent pattern. Of course, if the relationship of glossiness is reversed, it is possible to obtain a cosmetic material in which the relationship of the unevenness is reversed.

  According to this method, it is possible to easily give a three-dimensional unevenness to any substrate simply by preparing two kinds of paints having different gloss without the need for special chemicals. it can. In addition, the formation of paint layers with different gloss can be performed by conventional printing methods such as gravure printing, following the formation of the pattern, so there is no need for special equipment, high production efficiency, and synchronization with the pattern. Easy. In addition, the thickness of the paint layer can be much thinner compared to the height difference of the unevenness to be expressed, so that the amount of resin used can be saved, and it is also advantageous in terms of flexibility, making it suitable for bending processing. Excellent cosmetics can be easily realized. Moreover, since there is no excessive unevenness | corrugation on the surface of a decorative material, there also exists an advantage that a contaminant does not accumulate in a recessed part.

  In view of these many advantages, cosmetic materials that employ this method have already been used in large quantities, but the reality is that they have not yet surpassed the method of actually forming irregularities in terms of luxury. Considering the reason, for example, according to the mechanical embossing method, it is possible to faithfully reproduce the uneven shape of a natural wood conduit or the like including its cross-sectional shape. On the other hand, in this method using two kinds of paints having different glosses, since there are two kinds of surface gloss stages, there are two kinds of unevenness stages that can be expressed. Therefore, there is a problem that it is not possible to express an uneven shape having a slope portion whose depth (height) continuously changes, such as a natural wood conduit.

Therefore, by providing a gloss adjustment layer that expresses uneven shapes with slopes whose depth (height) has changed continuously, the depth (height) can be continuously increased like a natural wood conduit. There has been proposed a decorative material that expresses an uneven shape with a changed slope (see, for example, Patent Document 1).
Japanese Patent No. 3629964

However, in the decorative material of Patent Document 1, it is necessary to provide a difference in the gloss state in order to obtain a more three-dimensional effect, and the gloss state of the portion expressing the concave portion or the convex portion is changed by adjusting the additive amount. However, there is a limitation on physical properties, and there is a limit in design only by adjusting the addition amount. Further, the glossy state of the portion not expressing the concave portion or the convex portion on the surface provided with a difference from the portion expressing the concave portion or the convex portion has the same limit.
On the other hand, a structure that has multiple layers to provide gradation and stacks by changing the glossy state can be considered, but it is costly and troublesome, and even if combined with a stepwise gradation method, it is only worth the cost. A design effect was not obtained.

  The present invention has been made in view of the above-described circumstances, and in a decorative material that expresses unevenness three-dimensionally due to the difference in glossiness of the surface, without requiring a complicated structure and manufacturing method, at a lower cost. The present invention provides a cosmetic material that further improves the expression of three-dimensional effect.

In order to solve the above problems, the present invention proposes the following means.
The present invention relates to a base material, a solid concealing layer provided on the base material, a design pattern provided on the solid concealment layer, corresponding to the expression area of a concave portion or a convex portion, the design pattern and the solid design A first gloss adjustment layer that covers the concealment layer and adjusts the gloss state, and has a gradation region that removes the pattern pattern directly above and gives a gradation to the gloss state in the vicinity of the outline of the pattern pattern. And a second gloss adjustment layer provided in a different gloss state on the first gloss adjustment layer, wherein the gradation area of the second gloss adjustment layer is the first gloss area. No gradation is provided from the interface on the one gloss adjustment layer side to the surface side to the position of 20% of the thickness of the second gloss adjustment layer, and the gradation region is within the range from the position to the surface side. It is characterized by being formed.

  According to the decorative material according to the present invention, when the unevenness is expressed by two layers having different glossiness states of the first glossiness adjustment layer and the second glossiness adjustment layer, the gradation level is gradually changed depending on the gradation region. Although a tone is given, it can be made more effective by providing the gradation region on the surface side which has a large visual influence. On the other hand, since no gradation is provided up to the position of 20% of the thickness of the second gloss adjustment layer from the interface on the first gloss adjustment layer side to the surface side, it is necessary to provide a gradation area. Cost can be reduced.

In the above-described decorative material, it is more preferable to provide a surface pattern provided immediately above the pattern on the first gloss adjustment layer.
According to the decorative material according to the present invention, by providing the surface pattern, it is possible to give a design that is viewed as a color pattern independently of the unevenness provided by the gradation region.

  According to the decorative material of the present invention, the gradation region of the second gloss adjusting layer is located at a position that is 20% of the thickness of the second gloss adjusting layer from the interface on the first gloss adjusting layer side toward the surface side. Is provided in the range from the surface side to the surface side, and it is possible to effectively improve the expression of stereoscopic effect by effectively providing stepwise gradations of glossy state at low cost without depending on the complicated structure and manufacturing method. Can do.

(First embodiment)
FIG. 1 shows a first embodiment according to the present invention. As shown in FIG. 1, a decorative material 1 according to this embodiment includes a base material 2, a colored solid hiding layer 3 provided on the base material 2, and a colored solid hiding layer 3. The pattern 4 corresponding to the expression region 9 of the part, the first gloss adjustment layer 5 that covers the colored solid hiding layer 3 and the pattern 4 and adjusts the gloss state, and the different gloss on the first gloss adjustment layer 5 And a second gloss adjusting layer 6 provided in a state. Details of each component will be described below.

The substrate 2 can be arbitrarily used without any particular limitation as long as it is usually used as a base paper for decorative materials. Specifically, for example, paper such as thin paper having a basis weight of about 23 to 100 g / m ² , resin-mixed paper, titanium paper, resin-impregnated paper, flame retardant paper, inorganic paper, and woven fabric made of natural fibers or synthetic fibers. Cloth or non-woven fabric, homo- or random polypropylene resin, polyolefin resin such as polyethylene resin, copolymer polyester resin, amorphous crystalline polyester resin, polyethylene naphthalate resin, polybutylene resin, methyl methacrylate resin, polymethyl methacrylate resin, etc. Synthetic resin base materials such as acrylic resin, styrene resin, polyamide resin, fiber resin, polycarbonate resin, polyvinyl chloride resin, polyvinylidene chloride resin, fluorine resin, wood veneer, veneer, plywood, Laminated wood, particle board, wood base material such as medium density fiberboard, gypsum board, Any conventionally known materials such as inorganic base materials such as cement board, calcium silicate board and ceramic board, metal base materials such as iron, copper, aluminum and stainless steel, or composites and laminates thereof can be used. Also, the shape is not limited at all, for example, a film shape or a sheet shape, a plate shape, an atypical molded body or the like.

  The colored solid hiding layer 3 and the pattern 4 are not particularly limited as constituent materials, but generally, a coloring agent such as a dye or pigment is dissolved or dispersed in a suitable solvent together with a suitable vehicle (matrix). A printing ink or coating material is used.

  Examples of such colorants include inorganic pigments such as carbon black, titanium white, zinc white, petal, yellow lead, bitumen, cadmium red, azo pigments, lake pigments, anthraquinone pigments, phthalocyanine pigments, isoindolinone pigments. , Organic pigments such as dioxazine pigments, or a mixture of two or more thereof can be used.

  Examples of the vehicle include oil-based nitrified cotton resin, two-component urethane resin, acrylic resin, styrene resin, polyester resin, urethane resin, polyvinyl resin, alkyd resin, petroleum resin, ketone resin, epoxy resin, Various synthetic resins such as melamine-based resin, fluorine-based resin, silicone-based resin, fiber-based resin, and rubber-based resin, or a mixture or copolymer thereof can be used.

  As the solvent, for example, toluene, xylene, cyclohexane, ethyl acetate, butyl acetate, methyl alcohol, ethyl alcohol, isopropyl alcohol, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, water, or a mixture thereof can be used. .

  In addition, various additives such as extender pigments, plasticizers, dispersants, surfactants, tackifiers, adhesion aids, drying agents, curing agents, curing accelerators or curing retarders are used as necessary. The

  For example, in the case of a wood grain pattern, as is well known, printing is usually performed by separating the color into a base solid, wood grain pattern, conduit pattern, or the like. Among these, the base solid and the wood grain pattern are provided as the colored solid hiding layer 3 in the decorative material 1 of the present invention, and the conduit pattern is provided as the pattern 4 corresponding to the expression area of the concave portion or the convex portion. Of course, in the present invention, the colored solid hiding layer 3 is not limited to a wood grain pattern, and can be appropriately applied to a stone pattern, an abstract pattern, or the like.

  The colored solid hiding layer 3 and the pattern 4 are generally formed by an appropriate printing method such as a gravure printing method, an offset printing method, a screen printing method, an electrostatic printing method, or an ink jet printing method. However, the present invention is not limited to this. For example, the base solid described above may be formed by a coating method such as a roll coating method, a knife coating method, or a die coating method. Other patterns can also be formed by any conventionally known image forming method. Note that a sealer layer may be provided between the base material 2 and the colored solid hiding layer 3.

  The first gloss adjusting layer 5 is composed of the same printing ink or coating agent as the constituent materials of the colored solid hiding layer 3 and the pattern 4 described above. However, since the first gloss adjustment layer 5 needs to have transparency or translucency through which at least the colored solid hiding layer 3 and the pattern 4 can be seen through, a printing ink or a coating agent or the like for forming the transparency As such, it is necessary to use one containing no colorant such as a dye or a pigment, or containing only a small amount so as not to impair the required transparency.

  Moreover, since the 1st glossiness adjustment layer 5 comprises the outermost surface layer of the cosmetic material 1 in the expression area 9 of a recessed part or a convex part so that it may mention later, abrasion resistance required as the cosmetic material 1 or In order to have surface physical properties such as scratch resistance, solvent resistance, and contamination resistance, it is preferable to use a material mainly composed of a curable resin. Specifically, for example, thermosetting resins such as melamine resins, epoxy resins, amino alkyd resins, urethane resins, polyester resins, silicone resins, ionizing radiation curable resins such as acrylic resins, etc. Can be preferably used. Moreover, what adds a silica, an alumina, a calcium carbonate, barium sulfate etc. as a gloss adjusting agent to these mixtures etc. can be used. Here, ionizing radiation generally refers to radiation that has an ionizing effect on a substance, and includes X-rays, γ-rays, β-rays (electron beams), and short-wavelength ultraviolet rays. Since resin can also be used, long wavelength ultraviolet rays that do not have an ionizing effect are included.

  The second adjustment layer 6 is composed of a printing ink or a coating agent having transparency or semi-transparency, like the first gloss adjustment layer 5, and has the same curability as described above. It is preferably a resin, and more preferably an ionizing radiation curable resin. As the ionizing radiation resin, specifically, an ionizing radiation curable monomer that does not have a risk of thickening with time during printing is used. This resin does not increase in viscosity because the curing reaction does not proceed in a coating solution at room temperature during printing. On the other hand, after irradiation with ionizing radiation, the curing reaction proceeds rapidly and completely cures. Therefore, there is an advantage that even if the printed matter is wound up or stacked, there is no fear of blocking due to poor drying.

  As the ionizing radiation curable monomer, a compound having an ethylenically unsaturated double bond can be used, and these include a monofunctional monomer, a bifunctional monomer, and a trifunctional or higher polyfunctional monomer. Usually, the monomer is non-hydrophilic and has no hydrophilicity, for example, it does not have any of —CHO group, —OH group and —COOH group.

  Specifically, the monofunctional monomer having an ethylenically unsaturated double bond includes 2- (2-ethoxyethoxy) ethyl (meth) acrylate, stearyl (meth) acrylate, tetrahydrofurfuryl (meth) acrylate, lauryl ( (Meth) acrylate, 2-phenoxyethyl (meth) acrylate, isodecyl (meth) acrylate, isooctyl (meth) acrylate, tridecyl (meth) acrylate, caprolactone (meth) acrylate, ethoxylated nonylphenol (meth) acrylate, propoxylated nonylphenol (meta) ) Acrylate, phenoxyethyl (meth) acrylate, phenoxydiethylene (meth) acrylate, ethylene oxide modified nonylphenyl (meth) acrylate, methoxytriethylene glycol Lumpur (meth) acrylate, ethylene oxide 2-ethylhexyl (meth) acrylate, isobornyl (meth) acrylate and dipropylene glycol (meth) acrylate. Here, for example, stearyl (meth) acrylate indicates stearyl acrylate and / or stearyl methacrylate (hereinafter the same).

  Bifunctional monomers include 1,3-butanediol di (meth) acrylate, 1,4-butanediol di (meth) acrylate, polyethylene glycol di (meth) acrylate, polypropylene glycol di (meth) acrylate, neopentyl glycol di (Meth) acrylate, propoxylated neopentyl glycol di (meth) acrylate, ethoxylated neopentyl glycol di (meth) acrylate, hydroxypivalic acid neopentyl glycol di (meth) acrylate, (hydrogenated) bisphenol A di (meth) acrylate , (Hydrogenated) ethylene oxide modified bisphenol A di (meth) acrylate, (hydrogenated) propylene glycol modified bisphenol A di (meth) acrylate, 1,6-hexanediol di (meth) Acrylate, 2-ethyl-2-butyl - propanediol di (meth) acrylate, 1,9-nonanediol di (meth) acrylate.

  Examples of polyfunctional monomers include tris (2-hydroxyethyl) isocyanurate tri (meth) acrylate, ethoxylated trimethylolpropane tri (meth) acrylate, propoxylated trimethylolpropane tri (meth) acrylate, and propoxylated glyceryl tri (meth). Acrylate, pentaerythritol tri (meth) acrylate, trimethylolpropane (meth) acrylate, ethylene oxide modified trimethylolpropane (meth) acrylate, propylene oxide modified trimethylolpropane (meth) acrylate, tris (acryloxyethyl) isocyanurate, penta Erythritol tetra (meth) acrylate, ditrimethylolpropane tetra (meth) acrylate, ethoxylated pentaerythritol tet (Meth) acrylate, penta (meth) acrylate ester, and dipentaerythritol hexa (meth) acrylate.

  As ionizing radiation curable monomers, monomers such as urethane (meth) acrylate, polyester (meth) acrylate, polyether (meth) acrylate, and polyacryl (meth) acrylate have low viscosity, so the surface after coating is smooth. This is desirable because the effect of throwing on the colored solid hiding layer 3 is improved.

  Here, a silicone oil is added to the ionizing radiation curable monomer used as the second gloss adjusting layer 6. This is to prevent dirt on the surface of the second gloss adjusting layer 6 from adhering to the surface as an anti-fouling agent, or to easily wipe off the adhering dirt with various detergents and solvents. Silicone oil is incorporated into a matrix resin composed of ionizing radiation curable monomers.

  Silicone oils include non-modified silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, carboxy-modified silicone oil, mercapto-modified silicone oil, carbinol-modified silicone oil, methacryl-modified silicone oil, phenol-modified silicone oil, and ionizing radiation reaction type. Silicone oil can be used. As the ionizing radiation-reactive silicone oil, a silicone polymer, prepolymer, or monomer that undergoes a cross-linking polymerization reaction by ionizing radiation to solidify is used. Specifically, a compound having a functional group having an acryloyl group, a methacryloyl group, a thiol group, an epoxy group, or a double bond at one end, both ends, or a side chain of silicone can be used. In the case of a functional group having a group or a double bond, each crosslinking agent is added. In particular, an ionizing radiation-reactive silicone oil having an acryloyl group or a methacryloyl group in one molecule with 1 to 20 functional groups and an average molecular weight of 1000 to 30000 is an excellent dispersibility in an ionizing radiation curable resin. It is more preferable in terms of improving reactivity. The amount of the silicone oil as described above is preferably 0.01 to 5% by weight based on the total weight of the ionizing radiation curable monomer. This is because when the amount of the silicone oil is less than 0.01% by weight, the effect of addition cannot be obtained, and when it exceeds 5% by weight, the aqueous resin such as the pattern 4 is repelled, resulting in poor adhesion. Because it will cause.

  Then, the second gloss adjustment layer 6 is a gradation that removes the pattern 4 on the first gloss adjustment layer 5 and gives a stepwise gradation to the gloss state in the vicinity of the outline of the pattern 4. An expression region 9 that has a region 7 and is visually expressed as a concave or convex portion is formed by the region 8 where the first gloss adjustment layer 5 is exposed immediately above the pattern 4 and the gradation region 7. is doing. The gradation region 7 is configured such that the gloss state changes continuously or stepwise. That is, as it progresses from the contour of the expression area 9 of the concave or convex portion to the inside, the glossy state near the glossy state of the surface of the region 9 changes to the glossy state in the portion other than the vicinity of the pattern 4 corresponding to the region 9. It has come to.

  More specifically, when expressing the concave or convex expression area 9 as a concave, the second gloss adjusting layer 6 is designed to have a higher gloss than the surface of the expression area 9. Moreover, in the vicinity of the contour of the expression area 9, the gloss of the second gloss adjustment layer 6 gradually increases as it moves away from the contour of the expression area 9 and goes into the formation portion of the second gloss adjustment layer 6. In this way, it is formed with gradation.

  On the other hand, when it is intended to express the concave or convex expression area 9 as a convex part, the second gloss adjusting layer 6 is designed to have a lower gloss than the surface of the expression area 9. Moreover, in the vicinity of the contour of the expression area 9, the gloss of the second gloss adjustment layer 6 gradually decreases as it moves away from the contour of the expression area 9 and moves into the formation portion of the second gloss adjustment layer 6. In this way, it is formed with gradation. When using a gravure printing plate, use the plate method of the corrosion method that uses a film during baking (multistage alignment is likely to occur due to expansion and contraction of the film) and the heliograss method. Since the position is difficult to shift even if multi-stage corrosion is performed, the gradation expression with higher registration accuracy can be achieved.

  Here, the gradation region 7 is the thickness of the second gloss adjusting layer 6 from the interface 6a on the first gloss adjusting layer 5 side to the surface 6b side in the thickness direction of the second gloss adjusting layer 6. It is not formed in the range 6d up to the position 6c of 20% of the length T6, but is formed in the range 6e from the position 6c toward the surface 6b. As described above, in the thickness direction, the gradation region 7 is formed in the region 6e on the surface 6a side from the position 6c of 20% of the thickness T6 of the second gloss adjusting layer 6 having a large visual influence. Thus, it is possible to more effectively give a gradual gradation in a glossy state.

  Note that the contour of the pattern 4 corresponding to the concave or convex expression area 9 is not necessarily exactly the same as the contour of the stepped region 9, and is slightly more than the contour of the stepped region 9. It may be displaced inward or outward. On the contrary, the apparent unevenness can be appropriately adjusted by positively shifting the contours of the two slightly. Further, by changing the direction and distance of deviation between the contours in the stepped region 9, it is possible to change the apparent unevenness depending on the location.

  In the expression of fine concave or convex portions such as a wood grain conduit, the portion where gradation is provided in the second gloss adjustment layer 6 is naturally fine, and it is highly sophisticated in printing plates and printing inks. Resolution is required. On the other hand, in a general two-component curable resin that is frequently used as a surface coating agent for decorative materials, the curing reaction proceeds during printing and the viscosity increases, resulting in plate clogging and lower gradation reproducibility. There is a case.

  Accordingly, the resin used for the second gloss adjusting layer 6 has a viscosity of 0.1 to 3.5 Pa · s. This is because when the viscosity is within this range, the interlaminar adhesion becomes suitable, and when the viscosity is less than 0.1 Pa · s, it becomes too flexible and easily collapses, and when it exceeds 3.5 Pa · s. This is because it becomes rigid and the adhesiveness between adjacent layers deteriorates.

  The gradation region 7 provided in the second gloss adjustment layer 6 is shown in FIG. 1 as a change in the gloss state even when the purpose is to express a continuous change in depth (height). Thus, in many cases, stepped gradation is more advantageous in terms of the three-dimensional appearance of the unevenness obtained visually. In particular, although the unevenness is very fine, such as wood conduit grooves, the tone of continuous tone is poor, and the three-dimensional feeling of the cross-sectional shape of natural conduit grooves is sufficient. In many cases, it is not possible to express in a gradation, so that it is preferable to use a stepwise gradation.

  Here, as a method of providing gradation in the gloss state of the second gloss adjustment layer 6, for example, a gravure printing method is used, and the plate depth or area ratio of the gravure printing plate is set so that a desired gradation is obtained. Do it while changing. In addition, printing methods such as a general offset printing method, a screen printing method, an electrostatic printing method, and an ink jet method are also appropriately used.

  The gradation is not limited to the gradation due to the change in the application amount of the ionizing radiation curable resin, and the gradation can be expressed by a change in the area ratio such as a halftone dot (not shown). In addition, a change in the coating amount and a change in the area ratio can be used together (not shown).

  However, in general, even if the printing plate has a halftone dot design, it is usually continuous somewhat due to the flow of the resin during printing, so these differences are not necessarily essential. In the following, for the sake of simplicity, the description will be made with reference to the stepped diagram as shown in FIG. 1 on the drawing, but this includes all the above-described various gradation expression techniques.

  By the way, when it is going to express the expression area 9 of a recessed part or a convex part as a recessed part, the surface of the expression area 9 of a recessed part or a convex part must be in the state with low gloss. For this purpose, when the colored solid hiding layer 3 corresponding to the concave or convex expression area 9 is exposed on the surface in the expression area 9 as in the example shown in FIG. 1, the colored solid hiding layer 3. It is necessary to add a gloss adjusting agent or the like to the printing ink or the like for forming the ink so as to adjust the gloss to a low level. On the contrary, when expressing the concave or convex expression area 9 as a convex part, the gloss of the surface after printing is high as printing ink for forming the pattern 4 corresponding to the expression area 9. It is necessary to use printing ink.

  Here, the positional relationship between the concave or convex expression area 9 and the colored solid hiding layer 3 corresponding to the expression area 9 will be described again. When only the bottom surface of the concave portion or the top surface of the convex portion is to express the concave portion or the convex portion having a color different from that of the other portion, the colored solid hiding layer 3 is formed with the same contour as the expression region 9. There is a need. On the other hand, when the concave or convex portion having the same color as the bottom surface or the top surface is to be expressed also on the slope portion of the contour of the concave or convex portion, the colored solid concealment layer 3 includes the second gloss adjusting layer 6 described above. It is preferably formed in a region extending to the contour of a region having gradation outside the expression region 9. For example, the latter configuration is recommended for the purpose of mimicking a conduit groove in a cross section of natural wood.

  In addition, when it is intended to express a state in which the color continuously changes on the slope portion of the contour of the concave portion or the convex portion, the second gloss adjustment layer 6 in the vicinity of the contour of the representation region 9 has a gradation. In the colored solid concealment layer 3, gradation may be provided in the color of the expression. Alternatively, it is also possible to achieve a visually approximate expression effect by positioning the contour of the colored solid hiding layer 3 in the middle of the contour of the second gloss adjustment layer 6 having gradation. it can. In addition, it is also possible to express a complex concavo-convex shape in which the concavo-convex sensation changes depending on the position by adopting a combination of the above various expression techniques depending on the position.

  In addition, like the decorative material 10 shown in FIG. 2, it is good also as what provides the surface pattern 11 on the 1st glossiness adjustment layer 5 directly on the pattern pattern 4 corresponding to the expression area 9 of a recessed part or a convex part. By providing the surface pattern 11 in this way, a design that can be viewed as a color pattern can be provided independently of the unevenness provided by the gradation region 7.

  As a specific application example of the decorative materials 1 and 10 of the present invention as shown in FIG. 1 or 2, as described above, the expression of the conduit groove of natural wood is the most representative. Since the conduit groove is physically a concave portion, generally, the surface of the conduit pattern portion has a low gloss, and the glossy second gloss adjusting layer 6 is provided on the surface excluding the conduit pattern portion. Adopted. However, like certain coniferous wood, the color of the bark is light and the expression of the tree species that the duct groove part appears to be lifted up may be more realistic if the gloss is reversed. . In addition, due to the reversal of the glossiness, there is a case where an original new conduit expression is obtained without being bound by the existing concept.

  And according to the decorative materials 1 and 10, since the second gloss adjusting layer 6 is provided on the surface so as to have a gradation in the glossy state, the depth (height) is increased like a natural wood conduit. ) Can express the uneven shape continuously changed. In particular, the gradation region 7 is in a range 6e on the surface 6b side from a position 6c of 20% of the thickness of the second gloss adjustment layer 6 from the interface 6a on the first gloss adjustment layer 5 side toward the surface 6b side. By being provided, the expression of the stereoscopic effect can be further improved by effectively providing stepwise gradations of the glossy state at low cost without depending on a complicated structure and manufacturing method.

  Further, by setting the viscosity of the resin forming the second gloss adjusting layer 6 to 0.1 to 3.5 Pa · s, the resin is too soft and does not flow out, and the depth (height) is preferably continuous. It is possible to express the uneven shape that has been changed, and the cosmetic material 1 can be continuously manufactured at high speed without being too hard to be provided. Moreover, the stress which arises when resin hardens | cures can be relieve | moderated suitably, and the peeling between layers can be suppressed suitably.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, it is implicitly assumed that the gloss state of the second gloss adjustment layer 6 in a portion other than the vicinity of the concave or convex expression region 9 is constant. However, the grain pattern of the second luster adjustment layer 6 is used for the purpose of expressing the luster difference between the spring lumber part and the autumn lumber part in natural wood or the luster difference depending on the angle between the cut surface and the grain direction. It is also possible to have a change in tune with. In this way, in combination with the faithful expression of the shape of the conduit groove described above, it is possible to obtain a decorative material that is closer to natural wood and has excellent design properties.

  Next, the details of the decorative papers 1 and 10 of the first and second embodiments will be described based on Examples 1 and 2 described below.

The decorative material 1 shown in FIG. 1 was produced by the steps shown below.
That is, impregnated paper (GFR-506, manufactured by Kojin Co., Ltd.) having a basis weight of 50 g / m 2 was used as the base material 2, and oil-based nitrified cotton resin-based gravure printing ink (“PCNT, manufactured by Toyo Ink Manufacturing Co., Ltd. As the colored solid hiding layer 3, one color was printed on the front surface, and a wood grain pattern was further printed. Next, as the pattern 4, a conduit pattern (pattern line number 150 lines) synchronized with the pattern pattern 4 was printed.

  Then, as the first gloss adjusting layer 5, a two-component curable urethane resin paint (“HIMAT G-G-”) is prepared by adding silica powder so as to cover the colored solid hiding layer 3 and the pattern 4. 125 HV: manufactured by Dainippon Ink & Chemicals, Inc., 100 parts by weight and “curing agent G-XA: Dainippon Ink & Chemicals, Inc.” by 10 parts by weight) were applied at a coating amount of 5 g / m 2 after drying.

Next, as the second gloss adjustment layer 6, a two-component curable urethane resin (“G-125 gloss” 50 parts by weight, “G-125 mat” 50 parts by weight, Agent G-XA: “Dainippon Ink Chemical Co., Ltd.”) is provided near the contour of the pattern 4 (number of lines 40-80 lines / cm, depth 0.1 mm or less). The decorative material 1 was able to be obtained by printing on the surface excluding the coating at a coating amount of 2 g / m ² after drying and drying by heating in an air atmosphere and curing.
