Description

The present invention relates to a decorative material.

In decorative materials used for decorating the surface of building materials, furniture, home appliances, etc., it is generally required to realize a design expression closer to that of natural materials.

As a decorative material that meets these demands, for example, a film printed with a pattern such as wood grain (hereinafter referred to as a pattern) is provided with a pattern pattern (hereinafter referred to as an uneven pattern) having an uneven shape matching the pattern. It is known that an embossed template having a concavo-convex shape is subjected to thermal pressure molding to synchronize the pattern with the concavo-convex pattern (Patent Document 1).

When a chemical product film made of an olefin-based or vinyl chloride-based thermoplastic resin is used as the film, the film is softened by heating during embossing by thermal pressure molding using an embossed template. In the case of industrial mass production of decorative materials, the thermoplastic resin film on which the pattern and the uneven pattern should be formed is supplied as a long strip film. The strip-shaped film is printed with a pattern while being conveyed under tension, and the uneven pattern is embossed while being conveyed under tension and the thermoplastic resin is heated and softened. In such a case, in general, the film size is stretched in the longitudinal direction (that is, the extending direction) of the strip film, and at the same time, in the width direction of the strip film (that is, the direction orthogonal to the extending direction). Shrinkage occurs. As the film shrinks, the pattern printed on the film also shrinks, so it is difficult to stably synchronize (that is, register) the pattern with the uneven pattern.
In the case of patterns that are continuous in the longitudinal direction of the film, such as wood grain patterns, hairlines, and striped patterns, the error in the positional synchronization between the pattern and the uneven pattern in the longitudinal direction is originally inconspicuous, so the pattern and unevenness are inherently inconspicuous. In many cases, the accuracy of positioning with the handle does not matter.
However, even in that case, the error in the positional synchronization between the pattern and the uneven pattern in the width direction is still conspicuous. Therefore, when the strip-shaped film is used as the base material, the accuracy of positioning the pattern and the uneven pattern in the width direction has been an issue.

Japanese Unexamined Patent Publication No. 2011-83908

Patent Document 1 discloses a method of adjusting the dimensions of an embossed template in consideration of deformation during embossing.
However, in particular, the pattern is a pattern in which a plurality of different patterns are adjacent to each other in the width direction of the decorative material, such as a wood grain siding pattern, a tiled pattern, a brickwork pattern, and a masonry pattern as shown in FIG. In the case of a bumped pattern), the error in the positional synchronization between the pattern and the uneven pattern, especially in the width direction, is conspicuous among the seams (hereinafter, also referred to as bumped parts) where the different patterns are combined. easy. Then, it is extremely difficult to stably synchronize the pattern and the uneven pattern at all of the abutting portions (seam locations) that are present at a plurality of locations. Therefore, when the decorative material after production is visually inspected, there is a problem that a sense of incongruity remains in the portion where the pattern and the uneven pattern are misaligned, which hinders the improvement of the design.

The present invention is a decorative material obtained by superimposing a pattern of a bumping pattern and an uneven pattern of a bumping pattern, and the bumping portion does not cause a visual discomfort, especially even at a seam in the width direction.

The boundary lines A', B', and C'of the abutting portion in the transparent layer 4 overlap with the boundary lines A, B, and C of the abutting portion in the print layer 2, respectively. Stacked on top. At this time, as shown in FIG. 4, the abutting portion of the transparent layer 4 is arranged so as to overlap _{the buffer pattern region D 1 + 2 of the print layer 2.}
In addition, in FIG. 3, the boundary line of each abutting portion is conspicuous in the drawing and is exaggerated with a thick line for easy recognition, but in the actual decorative material, the abutting portion is not necessarily shown. Each boundary line does not always show a conspicuous appearance such as a thick line.

However, in consideration of simplification and legibility of the illustration, in FIG. 3, a rectangular shape which is a plan view shape of the decorative material 10 which is a laminated body of the base material 1, the printing layer 2, and the transparent layer 4. The appearance of the above is omitted, and only a part of the total length in the longitudinal direction (Y-axis direction) is extracted from only the two layers of the print layer 2 and the transparent layer 4 in the laminate. , As a conceptual diagram, is a illustrated plan view.

Further, the pattern area D ₁ and the pattern area D ₂ extend in the longitudinal direction Y orthogonal to the width direction X, and _{both the pattern areas D 1} and D ₂ are rectangular in the so-called plan view viewed from the Z-axis direction. Make a shape. In the present invention, the terms in the width direction and the longitudinal direction do not mean relative lengths and shorts, but are used simply to distinguish two orthogonal directions from each other. Further, the pattern area of FIG. 3 is merely an example of one embodiment, and the pattern area in the present invention may be at least two types, and from the arrangement of three types, four types, or five or more types of pattern areas. It may be configured. Further, the shapes of the pattern areas D ₁ and D ₂ are not limited to rectangles, and may be other polygons such as triangles, squares and rhombuses, polygons such as hexagons, or shapes other than polygons. ..
The pattern is not particularly limited, but for example, a wood grain pattern on the surface of various trees such as cedar, cypress, pine, oak, oak, and teak, a marble pattern (for example, a concave pattern on the surface of a travertin marble plate), and an opening on the surface of a granite There are stone patterns that imitate the surface of rocks such as surfaces, fabric patterns that imitate the texture or stitch pattern of cloth and cloth fibers, tiled patterns, brick pile patterns, etc., and parquet, patchwork, etc. that combine these patterns. There is also a pattern of.
These patterns are formed by multicolor printing using ordinary yellow, red, blue, and black process colors, and plates of the individual colors that make up the pattern (hereinafter referred to as multiple color separation plates) are prepared. It is also formed by multicolor printing and the like.
The same ink as the colored layer can be used to form the pattern layer.
As the printing method, various printing methods such as gravure printing, flexographic printing, silk screen printing, and ink jet printing can be applied.

It is preferable that the picture P _{1 + 2} constituting the buffer picture area D _{1 + 2} adjacent to both picture areas D ₁ and D ₂ includes at least a part of the features of the picture P ₁ and at least a part of the features of the picture P _2.
The feature of the pattern is a color, or an external feature selected from the pattern density of the characteristic pattern in the case of a pattern including a characteristic pattern such as a conduit groove or an annual ring such as a wood grain pattern having a conduit groove or an annual ring. Means.

It is preferable that the picture P _{1 + 2} and the picture P ₁ are continuously connected at the abutting portion, and the picture P _{1 + 2} and the picture P ₂ are continuously connected at the abutting part.
The above-mentioned "the pattern P _{1 + 2} and the pattern P ₁ are continuously connected at the abutting portion" means that the pattern P _{1 + 2} ′ of the width direction region ΔD _{1 + 2} ′ adjacent to the pattern area D _{1 in the buffer pattern area D 1 + 2 As the feature amount n 1 + 2} ′, which is obtained by extracting and quantifying the features, _{becomes smaller as the width of ΔD 1 + 2} ′ decreases (that is, _{the area of ΔD 1 + 2} ′ becomes smaller and is composed only of the region closer _{to D 1).} ), It means that the features of the _{pattern P 1} are extracted and converged to the _{quantified feature amount n 1.}
The above as "picture _{P 1 + 2} and the picture _{P 2} is continuously connected with突付portion", among the buffer picture area _{D 1 + 2,} the width direction region [Delta] D _{1 + 2} adjacent to the picture area _{D 2} "pattern _{P 1 +} 2 for" _{The feature amount n 1 + 2} ″, which is obtained by extracting and quantifying the features of, has _{a width of ΔD 1 + 2} ″ (that is, as _{the area of ΔD 1 + 2} ″ becomes smaller and is composed only of a region closer _{to D 2).} It means that the features of the pattern P ₂ are extracted and converged to the _{quantified feature amount n 2 with the reduction.}
The above-mentioned feature amount is preferably a feature amount extracted from at least one of the color density and / or the pattern density.

The feature amount of "color density" is in each position coordinate of the pattern (usually represented by each pixel or halftone dot constituting the pattern) when the plane in which the pattern exists is the XY plane. It can be extracted using an index that identifies the color. Typically, the CIE (Commission Internationale ^{de l'Eclairage) default L *} a ^* b ^* color system values; L ^* (x, y), a ^* (x, y), b ^* (x, y) Can be used. In addition, spectrum 3 stimulus values; (X (x, y), Y (x, y), Z (x, y) can be used. Uppercase letters mean 3 stimulus values, lowercase letters mean position coordinates. To do.

The feature amount of "characteristic pattern density" is generally extracted using the area occupancy, that is, the ratio of the total area of the characteristic pattern within the unit area in the area. can do. In particular, in the case of a linear pattern such as a conduit groove or an annual ring, the linear density of the pattern, that is, the number of lines in the unit area or the unit length in the direction orthogonal to the extending direction of the linear pattern. The number of hits is used.

As described above, the boundary lines A', B', and C'of the abutting portion in the transparent layer 4 of FIG. 3 are the boundary lines A, B, and C of the abutting portion in the print layer 2, respectively. When laminated so as to overlap, the abutting portion of the uneven pattern region is arranged at a position where it overlaps with the _{buffer pattern region D 1 + 2.}
In a decorative material having a pattern and an uneven pattern overlapped, one of the factors that causes a visual discomfort at the abutting portion is that the base material shrinks or expands during thermal pressure molding using an embossed template when forming the uneven pattern. It is conceivable that this will occur and the abutting portion of the pattern and the abutting portion of the uneven pattern region will be misaligned. According to the above configuration of the present invention, even if the base material shrinks or expands during thermal pressure molding using the embossed template at the time of forming the concave-convex pattern, the abutting portion of the concave-convex pattern region is a buffer pattern region. as long as it is disposed in a range overlapping the D 1 _{+ 2,} it is possible to avoid the discomfort caused by the misalignment that is, such a buffer picture area D _{1 + 2} position tuning error between the picture and the uneven pattern (misregister, misregister It has a function to absorb the influence (uncomfortable appearance).

The above effect is further enhanced by increasing the similarity between the picture P _{1 + 2} and the picture P _{1 and} the similarity between the picture P _{1 + 2} and the picture P ₂ higher than the similarity between the picture P ₁ and the picture P _2. be able to.
As used herein, "similarity" means psychological similarity. The "similarity" can be measured, for example, by comparing and quantifying the feature quantities such as color, shape, and texture extracted by an image analyzer.

The specific method for increasing the similarity between the picture P _{1 + 2} and the picture P _{1 and} the similarity between the picture P _{1 + 2} and the picture P ₂ is higher than the similarity between the picture P ₁ and the picture P _{2 is particularly limited.} However, for example, the following method 1 or method 2 or a combination thereof can be exemplified.

_{(3) After that, d 1} (x, y) + d ₂ (x, y _{) obtained by adding d 1} (x, y) and d ₂ (x, y), which are continuous changes in the vicinity of the boundary, in the plane. ) Is the density and / or the density of the pattern in the pattern areas D ₁ and D _2.
(4) A method of processing so that the density change of the pattern on the boundary becomes gentle as described above. A method of performing so-called watermark composition processing.

Specifically, each of the above processes uses, for example, an arithmetic control device, a memory, and an image processing device including an input interface, and stores the image data of _{P 1} and P _{2 in the memory via the input interface.} It can be performed by performing arithmetic processing on the data read from the memory by the arithmetic control device using a predetermined arithmetic formula and creating synthetic data.

The lower limit of W _{1 + 2} is the registration error in the width direction of the embossing machine used for forming the uneven pattern.
Further, it is more preferable to satisfy the relationship of 0.05 <W _{1 + 2} / W ₁ <0.1 and 0.05 <W _{1 + 2} / W _{2 <0.1.}

(Concave and convex pattern)
The present invention is not limited to the so-called "synchronization" type decorative plate in which the design of the pattern and the design of the uneven pattern are superposed as the same one. For example, the pattern is composed of a wood grain pattern, and the uneven pattern is a non-wood grain pattern. It can be composed of a pattern (for example, a matte portion).
When the uneven pattern is composed of a matte portion, the fine recesses constituting the matte portion are embossed rolls whose surface is made uneven by laser processing or etching processing, or embossed rolls whose surface is made uneven by a coating liquid containing a matting agent. It can be formed by embossing. In particular, by using laser processing, fine processing can be realized.

[Production method]
The manufacturing method described below includes a step (step A) of printing a pattern on the surface of a base material in the form of a film (hereinafter, also referred to as a base film) to form a print layer 2 and a print layer 2 A step of laminating the transparent layer 4 on the transparent layer 4 (step B) and a step of forming the uneven pattern 3 on the transparent layer 4 (step C) are included.

(Step A)
A printing roll (not shown) is used to form a printing layer 2 on one surface of a base film 11 made of a biaxially stretched polyester resin (PET-G) film, that is, a pattern is printed. For example, in gravure printing, a wood grain pattern can be formed by multicolor printing.
Printing a pattern includes a step of producing a manuscript image. Since the manuscript image is preferably digital data, if it is not digital data, it is converted into digital data by using a photograph, a scanner, or the like. Further, when the pattern is designed by using digital data using CAD or the like from the beginning, the digital data can be used. With this, the original image can be obtained as digital data.
In the process of producing the manuscript image, _{the picture P 1 constituting the picture area D 1} and the picture P ₂ forming the picture area D ₂ are acquired, and the features _{of the picture P 1} and the picture P ₂ are captured by the image analyzer. extracting and determines a pattern P _{1 + 2} with at least a portion of at least a portion of the pattern P _2, wherein the characteristic pattern P _1, having a pattern P _{1 + 2} between the picture area D ₁ and the picture area D ₂ A manuscript image provided with the buffered pattern region D _{1 + 2 is prepared.}

(Step B)
A transparent resin film is attached onto the print layer 2 formed in step A, and the transparent layer 4 is laminated. That is, an overlayer is formed. For example, the transparent layer 4 can be laminated and formed by laminating a transparent resin film (PET-G) on the printed surface with a (two-component curable) adhesive by dry lamination.

(C step)
On the surface of the transparent layer 4, an embossing roll having an uneven pattern is used to align the abutting portions of _{the uneven pattern area d 1} and the uneven pattern area d ₂ so as to be overlapped with the _{buffer pattern area D 1 + 2.} , Emboss.
The embossing roll used for embossing can be obtained by, for example, the following method.
<< Process of creating a manuscript image >>
In the process of producing a manuscript image, a pattern to be expressed as an uneven pattern is acquired and used as a manuscript image. Since it is preferable that the manuscript image is digital data of the in-plane distribution of image density, a wood board of cedar grain and a wood board of cedar grain are prepared as manuscripts, and both wood grains are read by using a digital scanner. Digital data of a shade image having a resolution of 2540 dpi is obtained in a TIFF format with an 8-bit image shade gradation (256 gradations).
<< Process of making a plate >>
In the step of producing the plate, an embossed plate (molding mold for decorative material) is produced based on the block copy image. Specifically, it comprises the following procedures (1) to (5).

(1) Image creation process for shade gradation block copy Using the original image digital data obtained in << Process for creating original image >>, a part with a width of 25 cm and a length of 90 cm is cut out from the image data of the cedar plate, and this is shown in the figure. Let it be an image of the uneven pattern region d1 in 3.
Further, a portion having a width of 25 cm and a length of 90 cm is cut out from the image data of the cedar grain, and this is used as an image of the uneven pattern region d2 in FIG.
Further, a portion having a width of 5 cm at the right end of the uneven pattern region d1 and a portion having a width of 5 cm at the left end of the image data of the cedar grain are selected, and both image data are subjected to continuous densification processing as described in FIG. 6 and the above specification. After applying, the right end of the uneven pattern area d1 with a width of 5 cm and the left end of the image data of the cedar grain with a width of 5 cm are combined (added) to perform watermark composition processing. Let it be the image data of the buffered uneven pattern region d1 + 2 in FIG.
After that, the image data of the concavo-convex pattern region d1, the image data of the concavo-convex pattern region d2, and the image data of the buffered concavo-convex pattern region d1 + 2 thus obtained are combined from the image data in the arrangement as shown in FIG. Create image data under the grayscale gradation plate. This shading gradation block copy image data is also referred to as uneven pattern image data.
(2) Metal roll preparation step In parallel with the above step (1), a metal roll for embossing plate engraving is prepared.
(3) Laser light engraving process Using a laser light direct engraving machine, the surface of the metal roll prepared in step (2) is engraved based on the uneven pattern image data created in step (1). As a result, a concavo-convex shape having the same plan view shape as the concavo-convex pattern on the surface of the decorative material and having an inverted concavo-convex shape (the portion corresponding to the convexity of the decorative material becomes concave on the embossed plate surface) is formed on the surface.
The metal roll is driven via the rotation drive shaft, and rotates around the rotation drive shaft as a central axis. The entire surface of the metal roll is scanned with a fiber laser beam L having an oscillation wavelength of 1024 nm, a laser spot diameter of 10 μm, and an output of 600 W emitted from the laser head. In that case, the laser beam is switched ON-OFF (switching between irradiation and non-irradiation) according to the density value of the uneven pattern image data created in step (1), and the irradiation position is determined by evaporation of metal by the laser beam. A recess with a depth of 10 μm is formed. Scanning of the metal roll surface with the laser beam is repeated a plurality of times. Further, in order to prevent the evaporated metal from becoming powder and remaining or adhering to the surface of the metal roll, the laser is in a state where the engraving liquid T is sprayed from the engraving liquid discharge head onto the laser light irradiation region on the surface of the metal roll. It is preferable to irradiate with light. For example, in the position coordinates of the image density corresponding to the plate depth of 50 μm on the uneven pattern image data, the laser beam is irradiated (ON) only for the first 5 scans out of a total of 10 scans, and the remaining 5 scans are irradiated (ON). The laser beam is controlled so as not to be irradiated (OFF). The scanning of the laser beam is completed to form a desired uneven shape on the surface of the metal roll.
At that time, the electronic computer which controls the laser beam directly engraving machine, maximum density data plate depth 200 [mu] m in the pattern region D _1, on the converted maximum density data of picture area D ₂ in plate depth 200 [mu] m, irradiation frequency of the laser beam To control.
(4) Electric field polishing step After cleaning the engraving liquid, electrolytic polishing is performed to remove metal residues adhering to the surface of the metal roll.
(5) Chromium Plating Step After the step (4), a chrome layer is formed on the surface of the metal roll by plating.
As described above, it is possible to obtain a plate (molding mold for decorative material, embossed plate in this embodiment) having an uneven shape in which the unevenness of the uneven pattern formed on the surface of the uneven layer is inverted.

FIG. 7 shows an explanatory view of the print layer 2 viewed from the upper surface (Z-axis direction of the coordinate axes) in a plan view and an explanatory view of the transparent layer 4 viewed from the upper surface. The boundary lines A', B', and C'of the abutting portion in the transparent layer 4 overlap with the boundary lines A, B, and C of the abutting portion in the print layer 2, respectively. Stacked on top. At this time, as shown in FIG. 8, the abutting portion of the print layer 2 is arranged so as to overlap _{the cushioning uneven pattern region d 1 + 2 of the transparent layer 4.}
In addition, in FIG. 7, the boundary line of each abutting portion is conspicuous in the drawing and is exaggerated with a thick line for easy recognition, but in the actual decorative material, the abutting portion is not necessarily shown. Each boundary line does not always show a conspicuous appearance such as a thick line.

(Concave and convex pattern)
The present invention is not limited to the so-called "synchronization" type decorative plate in which the design of the pattern and the design of the uneven pattern are superposed as the same one. For example, the pattern is composed of a wood grain pattern, and the uneven pattern is a non-wood grain pattern. It can be composed of a pattern (for example, a matte portion).
When the uneven pattern is composed of a matte portion, the fine recesses constituting the matte portion are embossed rolls whose surface is made uneven by laser processing or etching processing, or embossed rolls whose surface is made uneven by a coating liquid containing a matting agent. It can be formed by embossing. In particular, by using laser processing, fine processing can be realized.
When the concavo-convex pattern is composed of a matte portion, _{it is preferable that the concavo-convex pattern regions d 1} and d ₂ satisfy the following conditions, respectively.
The ten-point average roughness (Rz _{i of d 1} and Rz _{i + 1 of d 2} ) at JIS B0601: 1994 when the cutoff value is 8 mm is preferably a difference of 10 μm or more between them, but unevenness. This does not apply depending on the pattern of the pattern.

The concavo-convex pattern p _{1 + 2} constituting the buffer concavo-convex pattern region d _{1 + 2} adjacent to both concavo-convex pattern regions d ₁ and d ₂ is at least a part of the features of the concavo-convex pattern p ₁ of the concavo-convex pattern region d _{1 and the concavo-convex pattern region d 2} it is preferable to provide at least some of the features of the uneven pattern p _2.
The characteristic of the uneven pattern means a characteristic of surface texture including surface roughness.

It is preferable that the concave-convex pattern p _{1 + 2} and the concave-convex pattern p ₁ are continuously connected, and the concave-convex pattern p _{1 + 2} and the concave-convex pattern p _{2 are continuously connected.}
The above "concave and convex pattern p _{1 + 2} and uneven pattern p ₁ are continuously connected" means that, of the uneven pattern area d _{1 + 2} , the uneven pattern p _{1 + 2} ′ of the width direction region Δd _{1 + 2} ′ adjacent to the concave and convex pattern area d ₁ The feature amount n _{1 + 2} ′ extracted and quantified by the feature is converged _{to the feature amount n 1} obtained by extracting and quantifying the feature of the uneven pattern p _{1 of the uneven pattern area d 1 as the width of Δd 1 + 2} ′ is reduced. Means to do.
The above "concave-convex pattern p _{1 + 2} and concavo-convex pattern p ₂ are continuously connected" means that of the concavo-convex pattern region d _{1 + 2} , the concavo-convex pattern p _{1 + 2} "in the width direction region Δd _{1 + 2} " adjacent to the concavo-convex pattern region d _2. The feature amount n _{1 + 2} ″ extracted and quantified from the features converges _{to the feature amount n 2} quantified by extracting the features of the uneven pattern p _{2 in} the uneven pattern region d _{2 as the width of Δd 1 + 2 ″ is reduced.} Means to do.
The above-mentioned feature amount is preferably a feature amount extracted from the feature of surface texture including surface roughness.

As described above, the boundary lines A', B', and C'of the abutting portion in the transparent layer 4 of FIG. 7 are the boundary lines A, B, and C of the abutting portion in the print layer 2, respectively. When laminated so as to overlap, the abutting portion of the concave-convex pattern region is arranged at a position overlapping _{the buffer concave-convex pattern region d 1 + 2 of the transparent layer 4.}
In a decorative material having a pattern and an uneven pattern overlapped, one of the factors that causes a visual discomfort at the abutting portion is that the base material shrinks or expands during thermal pressure molding using an embossed template when forming the uneven pattern. It is conceivable that this will occur and the abutting portion of the pattern and the abutting portion of the uneven pattern region will be misaligned. As long as the abutting portion of the pattern region _{is arranged in a range that overlaps the cushioning concave-convex pattern region d 1 + 2} of the transparent layer 4, the base material shrinks during thermal pressure molding using the embossed template when forming the concave-convex pattern. Alternatively, even if the elongation occurs, the discomfort caused by the above-mentioned deviation can be avoided. That is, the buffered concave-convex pattern region d _{1 + 2} has a function of absorbing the influence (appearance discomfort) of the positional synchronization error (also referred to as registration error, registration deviation, etc.) between the pattern and the uneven pattern.

By making the similarity between the uneven pattern p _{1 + 2} and the concave-convex pattern p _{1 and} the similarity between the concave-convex pattern p _{1 + 2} and the uneven pattern p ₂ higher than the similarity between the concave-convex pattern p ₁ and the uneven pattern p _2. , The above effect can be further enhanced.
As used herein, "similarity" means psychological similarity. The "similarity" can be measured, for example, by comparing and quantifying the feature quantities such as color, shape, and texture extracted by an image analyzer.

To make the similarity between the uneven pattern p _{1 + 2} and the concave-convex pattern p _{1 and} the similarity between the concave-convex pattern p _{1 + 2} and the uneven pattern p ₂ higher than the similarity between the concave-convex pattern p ₁ and the uneven pattern p _2. The specific method is not particularly limited, and for example, the following methods 1 and 2 and combinations thereof can be exemplified.

<< Method 1 >> After arranging _{d 1} and d ₂ , a part of _{d 1} is cut out and pasted _{on d 2} , and a part of _{d 2 is cut out and pasted on d 1} by repeating the boundary. How to get used to.
