[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material for use in interior and exterior of buildings, surface fittings of furniture, furniture and the like. More specifically, the present invention relates to a decorative material in which unevenness is three-dimensionally represented by a difference in surface gloss.

[0002]

2. Description of the Related Art Conventionally, a decorative material for use in surface decoration of interior and exterior of buildings, fittings, furniture, and the like is usually provided with a desired pattern such as a wood grain pattern. . In addition to simply expressing wood grain patterns etc. in a plane, cosmetic materials that express three-dimensionally together with the unevenness of the surface such as conduits of natural wood, mainly for applications where a sense of luxury is desired, Widely used.

[0003] As a method for expressing a three-dimensional unevenness feeling in combination with a planar woodgrain pattern on the surface of a decorative material, various methods have been conventionally devised and used depending on the purpose.
As a representative method, for example, there are the following methods.

(1) An embossing plate, embossing roll, embossed film, or the like having a concavo-convex shape obtained by inverting a concavo-convex shape to be applied is pressed on the surface of a material for a decorative material, and the cosmetic is formed along the concavo-convex shape. A method of mechanically imparting an uneven shape by deforming a material for material (Japanese Patent Publication No. Sho 4
No. 7-18559). It is the most excellent in terms of the reproducibility of uneven shapes, and can be said to be the mainstream as a method for imparting unevenness to decorative materials. In addition to the method of applying to the surface of the already molded cosmetic material, an embossed plate or the like is pressed on the surface of the curable cosmetic material having fluidity in an uncured state, and simultaneously or simultaneously with shaping. There is also a method of curing after shaping (JP-A-51-5)
No. 58, JP-B-51-44790).

(2) An ionizing radiation-curable resin layer is formed on the surface of a material for decorative material, and is partially irradiated with ionizing radiation through a mask film or the like, and uncured ionizing radiation is cured at a non-irradiated portion. A method of forming a concave portion by removing the conductive resin later or utilizing a curing shrinkage phenomenon (Japanese Patent Publication No. 51-40 / 1976)
096, JP-A-48-4602).

(3) A pattern is applied to the surface or bottom surface of the curable resin applied to the surface of the material for decorative material with an ink containing a curing inhibitor or a curing accelerator, and then the curable resin is cured. A method in which the resin remaining uncured is removed later due to a difference in curing speed, or a concave portion is formed by utilizing a curing shrinkage phenomenon (Japanese Patent Laid-Open No. 53-120780, Japanese Patent Publication No. 46-36479).

(4) A pattern is applied to the surface or bottom surface of the heat-foamable resin layer with an ink containing a foaming accelerator or a foaming inhibitor, and this is heat-foamed to form a portion provided with the pattern and other portions. A method of forming an uneven shape by making the degree of foaming of the heat-foamable resin layer different between portions
No. 3-15713, JP-B-43-28636).

(5) A method in which a heat-foamable ink is printed in a pattern on the surface of a material for a decorative material, and is heated and foamed to form convex portions (JP-A-58-92562).

(6) A colored or uncolored solvent-free or high-solids ink is thickly raised on the surface of the material for decorative material by using a large gravure printing plate or a screen printing plate. Printing method (Japanese Patent Publication No. 50-14566)
issue).

(7) After forming a pattern of a portion to be a concave portion with an ink containing a liquid repellent substance such as a silicone compound or a fluorine compound on the surface of a material for a cosmetic material, the property of being repelled by the ink is considered. A method in which a concave portion is formed by applying a coating agent having the entire surface and repelling the coating agent on the pattern (Japanese Patent Publication No. 47-16629).

All of the above-mentioned methods are intended to realize a three-dimensional unevenness by actually forming the irregularities to be expressed on the surface of the decorative material. However, there are many restrictions on implementation. For example, in the case of (1), the material usable as a material for the decorative material is limited to a material having excellent embossing suitability (formability and holdability), and an expensive embossing plate or an embossing device is required. It is also difficult to synchronize the pattern with the uneven pattern. (2)
Items (5) to (5) require special resins, chemicals, equipment, and the like, and the production process is complicated, resulting in low productivity.

Since (6) uses a high-viscosity ink,
In addition to problems such as plate jams, it is not suitable for expressing delicate patterns. In (7), a special agent called a liquid repellent is required, and defects such as unrepelled portions are liable to occur. Further, as problems common to (6) and (7), when the area ratio of the convex portions is large, the amount of ink or paint for the convex portions becomes extremely large, and the physical properties of the concave portions are improved. Difficulty can be mentioned.

Another problem common to the methods (1) to (7) is that since the surface of the decorative material has an uneven shape, the area ratio of the concave portion is relatively small, particularly in the case of a conduit pattern of wood. When the size is too small, there is a problem that contaminants adhering to the surface of the decorative material easily accumulate in the concave portions and it is difficult to remove the contaminants accumulated in the concave portions even if the surface is wiped.

In contrast to the various methods described above, instead of actually forming the concave and convex shape to be expressed on the surface of the decorative material, the glossy state of the surface of the portion to be expressed as the concave portion and the convex portion is different from that of the human eye. There is also a method of visually expressing a three-dimensional effect of unevenness by using the illusion of. In other words, even if there is no uneven shape in reality, a relatively high gloss part is recognized as a convex part and a low gloss part is recognized as a concave part to human eyes.

[0015] Specifically, the above-mentioned method is applied to, for example, the entire surface of the base material on which an appropriate pattern including a dent pattern is printed,
After forming a low gloss transparent to translucent synthetic resin paint layer, a high gloss transparent to translucent synthetic resin paint layer is applied to the surface of the synthetic resin material layer except for the portion corresponding to the concave pattern. Is achieved by forming
39115). Of course, if the relationship between the levels of gloss is reversed, a cosmetic material in which the relationship between the irregularities is reversed can be obtained.

According to this method, a three-dimensional unevenness can be easily applied to any base material by preparing only two kinds of paints having different glosses without requiring a special agent or the like. can do. In addition, the formation of the paint layer having a different gloss can be performed by a conventional printing method such as a gravure printing method subsequent to the formation of the pattern, so that no special equipment is required, the production efficiency is high, and the synchronization with the pattern can be achieved. 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 reduced, and it is also advantageous in terms of flexibility, and is suitable for bending workability. Excellent cosmetic materials can be easily realized. In addition, there is also an advantage that contaminants do not accumulate in the concave portions because there are no very large irregularities on the surface of the decorative material.

In view of such many advantages, cosmetic materials employing this method are already used in large quantities,
In fact, it has not yet surpassed the various methods described above in terms of luxury. Considering the reason, for example, according to the mechanical embossing method of (1), it is possible to faithfully reproduce the uneven shape of a conduit or the like of a natural tree including its cross-sectional shape. On the other hand, in this method using two kinds of paints having different gloss, the level of gloss of the surface is 2
Since it is a type, there are two types of irregularities 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 conduit of a natural tree.

[0018]

SUMMARY OF THE INVENTION The present invention has been made to solve such problems, and an object of the present invention is to provide a decorative material which expresses an uneven shape by a difference in the gloss state of the surface. It is an object of the present invention to obtain a decorative material that expresses a concavo-convex shape whose depth (height) continuously changes, such as a conduit of a natural tree.

[0019]

According to the present invention, in order to solve the above-mentioned problems, a pattern including a pattern corresponding to a concave or convex expression area is provided on a base material, and the surface of a portion other than the area is provided with the pattern. A cosmetic material provided with a gloss adjusting layer having a gloss different from the surface of the region, wherein the gloss adjusting layer has a glossy gradation near the contour of the region. I do. Particularly, the present invention provides a decorative material, wherein the gloss adjusting layer is made of a curable urethane resin using a blocked isocyanate as a curing agent.

[0020]

FIG. 1 shows an example of a cross section of a decorative material obtained according to the present invention. This decorative material is a decorative material substrate 1
A picture 3 composed of a base pattern 31 and a pattern 32 corresponding to the concave or convex expressing area 2 is formed thereon, and the surface of the portion other than the concave or convex expressing area 2 has a concave or convex expressing. A gloss adjusting layer 4 having a gloss different from that of the surface of the region 2. The gloss adjusting layer 4 is provided with a gradation in a gloss state in the vicinity of the contour of the concave or convex expressing region 2. Have been. The “recess or projection expressing region” in the present invention means a region to be expressed as a depression or a projection in comparison with another portion (a portion where the gloss adjusting layer 4 is provided).

As the substrate 1, various materials can be used according to the intended use, as is conventionally known.
Specifically, for example, paper such as tissue paper, titanium paper, resin-impregnated paper, flame-retardant paper, inorganic paper, woven or non-woven fabric made of natural fiber or synthetic fiber, polyolefin resin, polyester resin, acrylic resin , Styrene resin, polyamide resin, cellulose resin, polycarbonate resin, polyvinyl chloride resin, polyvinylidene chloride resin, synthetic resin base material such as fluorine resin, veneer veneer, veneer, plywood, laminated wood, particles Wood-based substrates such as boards, medium-density fiber boards, gypsum boards, cement boards, calcium silicate boards, inorganic base materials such as ceramic boards, metal base materials such as iron, copper, aluminum, and stainless steel, and the like Conventionally known arbitrary materials such as a composite and a laminate can be used, and the shape thereof is not limited at all, for example, from a film shape to a sheet shape, a plate shape, and a molded product.

There are no particular restrictions on the constituent materials of the pattern 3,
Generally, a printing ink or coating material obtained by dissolving or dispersing a colorant such as a dye or a pigment in a suitable solvent together with a suitable binder resin is used.

Examples of the coloring agent include inorganic pigments such as carbon black, titanium white, zinc white, red iron oxide, graphite, navy blue, and cadmium red; azo pigments, lake pigments, anthraquinone pigments, phthalocyanine pigments, and isoindolinones. Organic pigments such as pigments and dioxazine pigments, or a mixture of two or more thereof can be used.

The binder resin includes, for example, an acrylic resin, a styrene resin, a polyester resin,
Urethane resin, polyvinyl resin, alkyd resin, petroleum resin, ketone resin, epoxy resin, melamine resin, fluorine resin, silicone resin, cellulose resin,
Various synthetic resins such as a rubber-based resin, or a mixture thereof, a copolymer, or the like can be used.

Examples of the solvent include toluene, xylene, cyclohexane, ethyl acetate, butyl acetate, methyl alcohol, ethyl alcohol, isopropyl alcohol, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, water and the like, and mixtures thereof. Can be used.

In addition, if necessary, extenders and plasticizers,
Dispersant, surfactant, tackifier, adhesion aid, desiccant,
Various additives such as a curing agent, a curing accelerator or a curing retarder are appropriately used.

The picture 3 needs to include at least the pattern 32 corresponding to the concave or convex expressing area 2. On the other hand, the base pattern 31 is not indispensable, but can be provided for the purpose of giving a design visible as a color pattern independent of surface irregularities to a portion other than the concave or convex expression region 2. For example, in the case of a wood pattern, as is well known, a solid groundwork, a wood pattern,
It is common to print by dividing into a conduit pattern or the like. Among them, the solid background and the grain pattern are provided as the ground pattern 31 in the decorative material of the present invention, and the conduit pattern is formed in the concave or convex expression area 2. Is provided as a pattern 32 corresponding to. Of course, in the present invention, the pattern 3 is not limited to a wood grain pattern, but can be appropriately applied to a stone pattern, an abstract pattern, and the like.

FIG. 1 shows a concave or convex expressing area 2.
Is described as being provided on the surface of the base pattern 31, but this does not necessarily define the vertical relationship between the two, and both are defined as a continuous pattern on the same surface. If provided, the vertical relationship may be reversed, or a transparent layer (or transparent substrate 1) may be interposed between the two. Also,
All or part of the picture 3 may be integrated with the base material 1 by mixing or penetrating the colorant into the base material 1. In short, it suffices that the pattern 32 corresponding to the concave or convex expressing region 2 and the base pattern 31 be configured so as to be distinguished in color when observed from the surface side of the decorative material.

Also, the contour of the pattern 32 corresponding to the concave or convex expressing area 2 does not necessarily need to exactly match the contour of the area 2 and is slightly inner or outer than the contour of the area 2. May be shifted. Rather, the apparent unevenness can be appropriately adjusted by positively shifting the contours of the two. In addition, by changing the direction and distance of the deviation between the two contours depending on the location in the region 2, the apparent unevenness can be changed depending on the location.

The method of forming the picture 3 is most commonly performed by an appropriate printing method such as a gravure printing method, an offset printing method, a screen printing method, an electrostatic printing method, an ink jet printing method, but is not limited thereto. However, for example, the above-mentioned base solid may be formed by a coating method such as a roll coating method, a knife coating method, or a die coating method, and other patterns can be formed by any conventionally known image forming method. .

As the constituent material of the gloss adjusting layer 4, the same printing inks or coating agents as those mentioned above as the constituent material of the picture 3 can be used. However,
Since the gloss adjusting layer 4 needs to have at least transparency so that the picture 3 can be seen through, the printing ink or the coating agent forming the same does not contain any coloring agent such as dye or pigment, It is necessary to use one containing only a small amount so as not to impair the required transparency.
In addition, since the gloss adjusting layer 4 constitutes the outermost surface layer of the decorative material, the abrasion resistance and abrasion resistance required for the decorative material,
In order to have surface physical properties such as solvent resistance and stain resistance, it is preferable to use a material containing a curable resin as a main component.
Specifically, for example, melamine resin, epoxy resin,
A thermosetting resin such as an aminoalkyd-based resin, a urethane-based resin, a polyester-based resin, and a silicone-based resin, and an ionizing radiation-curable resin such as an acrylic-based resin can be suitably used.

The gloss adjusting layer 4 needs to have a different gloss from the surface of the concave or convex expressing region 2. Specifically, when the concave or convex expression region 2 is to be expressed as a concave portion, the gloss is designed to be higher than the surface of the concave or convex expression region 2, and conversely, the concave or convex expression region 2 is designed. Is to be expressed as a convex part, it is necessary to design the gloss to be lower than the surface of the concave part or the convex part expressing area 2. In order to appropriately adjust the gloss state of the gloss adjusting layer 4, a gloss adjusting agent such as silica, alumina, calcium carbonate, barium sulfate or the like can be appropriately added.

In the present invention, in order to express a continuous change in depth (height) by a change in gloss state,
In the vicinity of the contour of the concave or convex expressing region 2, the gloss of the gloss adjusting layer 4 is provided with a gradation. That is, in the vicinity of the contour of the concave or convex expression region 2, as the gloss state of the gloss adjusting layer 4 progresses from the contour to the inside, from the gloss state close to the gloss state of the surface of the concave or convex expression region 2, The gloss adjusting layer 4 is configured to change continuously or stepwise until the gloss state of the gloss adjusting layer 4 in a portion other than the vicinity of the concave or convex expressing region 2 is reached.

More specifically, when the concave or convex portion expressing region 2 is to be expressed as a concave portion, the gloss adjusting layer 4 is designed to have a higher gloss than the surface of the region 2, and In the vicinity of the contour of the region 2, the gloss of the gloss adjusting layer 4 gradually increases as the distance from the contour of the region 2 advances to the inside of the portion where the gloss adjusting layer 4 is formed.
It is formed with gradation. Conversely, when the concave or convex expressing region 2 is to be expressed as a convex, the gloss adjusting layer 4
Is designed to have a lower gloss than the surface of the area 2;
In addition, in the vicinity of the contour of the area 2, the area 2
Is formed with a gradation so that the gloss of the gloss adjusting layer 4 gradually decreases as it goes away from the outline and enters the inside of the formation portion of the gloss adjusting layer 4.

As means for providing a gradation in the gloss state of the gloss adjusting layer 4, a plurality of types of printing inks or coating agents having different gloss states are applied to the gloss adjusting layer 4 from the vicinity of the contour of the concave or convex expressing area 2. A method of forming a print in order from the one having the lowest gloss to the inside of the formed portion is also conceivable, but the manufacturing process is complicated and registration is difficult, which is not very preferable. For example, it is preferable to adopt a method of changing the application amount of the printing ink or the coating agent by means such as changing the plate depth or area ratio of the gravure printing plate.

The gradation provided in the gloss adjusting layer 4 is not limited to a stepwise gradation (FIG. 1), but may be a continuous gradation (FIG. 2). However, in general, when the gradation is stepwise consisting of several steps, the change in the gloss state is emphasized and the tone tends to be stronger. Therefore, even when the purpose is to express a continuous change in depth (height), visually adopting a stepwise gradation (FIG. 1) as a change in the gloss state can be obtained. In many cases, it is advantageous in terms of the three-dimensional effect of the irregularities formed. In particular, when the size of the unevenness is very fine, for example, for example, a conduit groove of wood, the tone is poor in continuous gradation, and the three-dimensional effect of the cross-sectional shape of the natural conduit groove is sufficiently obtained. Since it is often not possible to express, it is preferable to use a stepwise gradation.

Further, the gradation is not limited to the gradation based on the change in the coating amount, but can be expressed by the change in the area ratio of halftone dots or the like (FIG. 3). And the change of the area ratio can be used together (not shown). However, in general, even when the printing plate is designed in a halftone dot shape, it is common that the printing plate is somewhat continuous due to the flow of the resin during printing. Therefore, these differences are not necessarily essential. For the sake of simplicity, the following description will be made with reference to a step type diagram as shown in FIG. 1, which includes all of the various gradation expression techniques described above.

In expressing fine concaves or convexes such as wood grain conduits, the portions where gradation is provided in the gloss adjusting layer 4 are also finely fine, and printing plates and printing inks are also highly sophisticated. High resolution is required. For example, in the case of gravure printing, it is necessary to use a printing plate having a fine screen, and ink and the like are required to have a performance of transferring a fine difference in plate depth or area ratio with good reproducibility. On the other hand, as described above, it is preferable to use a curable resin for the gloss adjusting layer 4 from the viewpoint of the surface properties, but a general two-part curable type which is frequently used as a surface coating agent for decorative materials. In resin,
During printing, the curing reaction proceeds, the viscosity increases, and plate clogging may occur, thereby reducing the reproducibility of gradation.

Therefore, it is preferable that the resin used for the gloss adjusting layer 4 is selected so as not to increase the viscosity over time during printing. Specifically, it is preferable to use a curable urethane-based resin using a blocked isocyanate as a curing agent. This resin does not increase in viscosity because the curing reaction does not progress in the coating liquid state at room temperature during printing, while curing after printing requires special equipment such as an electron beam or ultraviolet ray irradiation device Without drying, the block is released by the heat of the dryer in the drying process, and the curing reaction proceeds rapidly and is completely cured, so even if the printed matter is wound up or stacked, there is no risk of blocking due to poor drying. There are advantages such as.

When the concave or convex region 2 is to be expressed as a concave portion, the surface of the concave or convex region 2 must be in a low gloss state. For this purpose, as in the example shown in FIG. 1, when the pattern 32 corresponding to the concave or convex expressing region 2 is exposed on the surface in the region 2, the printing ink for forming the pattern 32 is formed. It is necessary to add a gloss adjusting agent or the like as needed to adjust to a low gloss state. Conversely, when the concave or convex portion expressing region 2 is to be expressed as a convex portion, the region 2
As a printing ink for forming a pattern 3 corresponding to
It is necessary to use a printing ink having a high gloss after printing.

As another method, as shown in FIG. 4, a picture 3 including a pattern 32 corresponding to the concave or convex expressing area 2;
Between the gloss adjusting layer 4 and the gloss adjusting layer 4, a second gloss adjusting layer 5 having a gloss state that the surface of the concave or convex expressing region 2 should have can be provided. The material of the second gloss adjusting layer 5 may be the same as or different from that of the gloss adjusting layer 4, but it is needless to say that at least the gloss is different from that of the gloss adjusting layer 4. That is,
When the region 2 is to be expressed as a concave portion, the gloss of the second gloss adjusting layer 5 is designed to be lower than the gloss of the gloss adjusting layer 4,
On the other hand, when it is intended to express as a convex portion, the gloss of the second gloss adjusting layer 5 may be designed to be higher than the gloss of the gloss adjusting layer 4.

As described above, when the second gloss adjusting layer 5 is provided, it is not necessary to adjust the gloss of the printing ink for forming the pattern 32 corresponding to the concave or convex expressing region 2. In particular, when it is desired to use the base material 1 having a rough surface such as paper and set the gloss of the region 2 high, the printing ink for the pattern 32 can be easily provided without being excessively thick. This has the advantage that the gloss of the area can be sufficiently increased.
In addition, since the pattern 32 is protected by the second gloss adjusting layer 5, there is also an advantage that the surface properties of the area 2 are improved. From this viewpoint, it is preferable that the second gloss adjusting layer 5 is also mainly composed of the curable resin.

The second gloss adjusting layer 5 does not necessarily need to be provided on the entire surface, but may be provided only on the concave or convex expressing region 2 (FIG. 5). Further, it can be provided in a region including a portion having a width outside the contour of the concave or convex expressing region 2 (FIG. 6). With the latter configuration, there is an advantage that even if the registration between the second gloss adjusting layer 5 and the gloss adjusting layer 4 is slightly shifted, there is no possibility that unnaturalness is generated in the unevenness. In addition, the gradation property of the gradation portion of the gloss adjustment layer 4 expresses the gloss state of the surface of the second gloss adjustment layer 5 as a base (for example, both the surface of the picture 3 and the gloss adjustment layer 4 have high gloss. When the second gloss adjusting layer 5 has a low gloss, the low gloss effect of the underlying second gloss adjusting layer 5 has an effect on the surface in a portion where the thickness of the gloss adjusting layer 4 is small. In the case where the gloss of the surface of the layer 4 is low, the second gloss adjusting layer 5 includes at least the concave or convex expressing region 2 and the gloss adjusting layer 4 near the contour of the region 2. It is preferable to provide in a region including both the region having the tone and the tone.

Here, the concave or convex expressing region 2 and
Referring again to the positional relationship with the pattern 32 corresponding to the region 2, when only the bottom surface of the concave portion or the top surface of the convex portion is to express a concave portion or a convex portion having a different color from other portions, The pattern 32 is formed to have the same contour as that of the region 2 (FIG. 4), but the slopes of the contours of the recesses or protrusions also represent recesses or protrusions having the same color as the bottom or top surface. In this case, it is preferable that the pattern 32 is formed in a region outside the region 2 and extending to the outline of the region where the gloss adjusting layer 4 has a gradation (FIG. 7).
For example, when the purpose is to imitate a conduit groove of a cross section of natural wood, the latter configuration is recommended.

When it is intended to represent a concave portion or a convex portion in which the color continuously changes on the slope of the contour of the concave portion or the convex portion, the gloss adjusting layer 4 near the contour of the region 2 is used. A gradation may be provided for the color of the pattern 32 in the region having the gradation (FIG. 8). Alternatively, by visually positioning the contour of the pattern 32 between the inner and outer contours of the region in which the gloss adjusting layer 4 has a gradation, a visually similar expression effect can be achieved (FIG. 9). In addition, by adopting the various expression techniques described above in combination depending on the position, it is possible to express a complicated uneven shape in which the sense of unevenness changes depending on the position.

As a specific application example of the present invention, the expression of a conduit groove of natural wood is the most typical, as already described many times. Since the conduit groove is physically a concave portion, a structure is generally adopted in which the surface of the conduit pattern portion is made low in gloss and the surface except for the conduit pattern portion is provided with a high gloss control layer 4. . However, in the case of a tree species, such as a certain kind of softwood, which has a light color of the skin of the tree, and in which the conduit groove portion appears to be raised, there is a case where the reverse of the gloss level is more realistic. In addition, the reversal of the luster may provide a unique new conduit expression without being bound by the established concept.

In the above description, the concave or convex expression region 2
It is implicitly assumed that the gloss state of the gloss adjusting layer 4 in a portion other than the vicinity is constant. For example, the difference in gloss between the spring wood portion and the autumn wood portion in natural wood, the cut surface and the grain Gloss adjustment layer 4 for the purpose of expressing the gloss difference etc. depending on the angle with the direction
The glossy state can have a change synchronized with the grain pattern. In this manner, in combination with the above-described faithful expression of the shape of the conduit groove portion, it is possible to obtain a decorative material which is closer to natural wood and has extremely excellent design.

[0053]

As described above, the cosmetic material of the present invention is
In the decorative material, a pattern including a pattern corresponding to the concave or convex expressing area is provided on the base material, and a gloss adjusting layer having a gloss different from the surface of the area is provided on the surface of a portion other than the area. The structure in which the gloss adjusting layer has a gradation in a gloss state in the vicinity of the contour of the region, for example, a slope portion having a continuously changed depth (height), such as a conduit groove portion in natural wood. The present invention has an excellent effect that a certain uneven shape can be faithfully expressed and a decorative material having an excellent design feeling can be obtained.

In particular, when the gloss adjusting layer is made of a curable urethane resin using a blocked isocyanate as a curing agent, the curing reaction does not proceed during printing and the viscosity does not increase. Because subtle gradation expression is not hindered by the process, and it can be completely cured in a short time by heat treatment in a dryer, it is necessary to take measures such as adding new equipment and reducing the printing speed. In addition, the present invention has an excellent effect that it can be extremely efficiently manufactured by in-line integrated production under substantially the same conditions as the conventional decorative material.
