Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a decorative sheet having an embossed concave portion in conformity with a printed pattern and having an excellent design effect.

[0002]

2. Description of the Related Art As a decorative sheet having a wood grain surface used for interior decoration of buildings, finishing of furniture, and surface decoration of other articles, conventionally, a roll-shaped colored polyvinyl chloride sheet and a roll-shaped transparent polyvinyl chloride sheet have been used. Using a vinyl sheet, provide a wood grain pattern printing layer on one side of the colored polyvinyl chloride sheet, and overlay the transparent polyvinyl chloride sheet on that side for continuous thermal lamination and at the same time the transparent polyvinyl chloride sheet surface. There is used a decorative sheet which is embossed on, and filled with colored ink by wiping in the embossed recesses, and then provided with a gloss adjusting layer on the surface thereof.

In the conventional decorative sheet as described above, a roll-shaped material is used to form a pattern printing layer on the surface of the colored polyvinyl chloride sheet by printing, and the pattern printing layer is provided in a separate step. Since a manufacturing method was adopted in which the colored polyvinyl chloride sheet and the transparent polyvinyl chloride sheet were overlaid and continuously embossed at the same time as thermal lamination, the pattern printing layer and the transparent polyvinyl chloride sheet printed on the colored polyvinyl chloride sheet were used. It was not possible to obtain a decorative sheet excellent in design close to natural wood grain, in which the embossing applied to the vinyl chloride sheet surface could not be synchronized, and the pattern printing layer and the recess of the conduit embossing were synchronized.

As a decorative sheet in which the pattern printing layer and the embossed concave portion are aligned, as described in Japanese Patent Application No. 5-26580, a flat plate press type embossing device is used, and the size is the same as that of the embossing type. Using a sheet-shaped transfer sheet provided with a print pattern, align the embossed die and the print pattern of the transfer sheet, and superimpose a transparent polyvinyl chloride sheet on the surface of the transfer sheet provided with the print pattern. Then, by applying an embossing die from the transparent polyvinyl chloride sheet side and applying pressure, the printed pattern is transferred to one surface of the transparent polyvinyl chloride sheet at the same time as the other surface of the transparent polyvinyl chloride sheet, A method for manufacturing a decorative sheet having an embossing that matches the printed pattern is known.

However, the above-mentioned flat plate press type embossing apparatus is used to manufacture a decorative sheet having an emboss in synchronization with the print pattern by using a sheet-shaped transfer sheet provided with a print pattern having the same size as the emboss type dimension. In the method, a transfer sheet provided with a printed pattern having the same size as that of the embossing mold must be manufactured. In order to manufacture such a transfer sheet, it is necessary to use a thick transfer sheet base material having excellent dimensional stability, which is costly.
There is a problem in that it is technically extremely difficult to provide a printed pattern having the same size as the embossed size by printing. Further, it is necessary to manually align the embossing die and the printed pattern of the transfer sheet and set them in the embossing device. Therefore, the transfer sheet becomes expensive, and the workability is very poor due to the manual production, which is not suitable for mass production.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to use a sheet-type transfer sheet provided with a print pattern having the same size as the embossing mold by using the flat plate press type embossing device. In addition to improving the shortcomings of the manufacturing method of the decorative sheet which is provided with the embossing synchronized with the printed pattern,
By using a roll-shaped transfer sheet and a roll-shaped plastic sheet that have not been implemented, it is possible to transfer the pattern printing layer to the plastic sheet and simultaneously perform high-speed continuous embossing in synchronization with the pattern printing layer. And then
It is possible to manufacture an inexpensive decorative sheet having an excellent design property close to that of natural wood grain in which the pattern print layer and the embossed recesses are aligned.

[0007]

[Means for Solving the Problems] A transfer sheet having a pattern printing layer provided on a transfer sheet substrate with a pattern printing pitch smaller than an embossing pitch is used, and the transfer sheet is provided on the surface on which the pattern printing layer is provided. By stacking the transparent plastic sheets and applying pressure between the embossing roll and the pressure roll, the pattern printing layer is continuously transferred to one surface of the transparent plastic sheet, and at the same time, the pattern printing layer is synchronized with the other surface. In the embossing, the method for producing a decorative sheet is characterized in that the embossing is synchronized with the pattern printing layer by adjusting the tension applied to the transfer sheet.

[0008] A pattern printing pitch mark is provided on the pattern printing layer, and an embossing pattern pitch mark is provided on the embossing roll. By feeding back the information from the pitch mark detection device for detecting the relative position of the pattern pitch mark to the tension control device, the tension of the transfer sheet is controlled by the tension control device to synchronize the pattern print layer and the emboss. It is a method for producing the above decorative sheet, which is characterized.

[0009]

[Function] The transfer sheet is manufactured so that the pattern print layer of the transfer sheet substrate is slightly smaller than the pattern print pitch embossed pattern pitch, and the pattern print layer is transferred to the transparent plastic sheet and embossed at the same time. At this time, by adding tension to the transfer sheet and stretching the transfer sheet base material within its elastic limit, the transfer sheet is made to have the same pattern printing pitch as the embossed pattern pitch of the pattern printing layer provided on the transfer sheet base material. By adjusting the tension of, it is possible to emboss in synchronization with the pattern printing layer transferred to the transparent plastic sheet.

Indicates the transfer sheet base material winding section, respectively.

The apparatus used in the method for manufacturing a decorative sheet of the present invention for performing embossing in synchronization with a printed pattern at the same time as transfer is shown in FIG. The transfer sheet 1 is ejected from the transfer sheet feeding section 21 and sent to the emboss section through the tension control device 25. On the other hand, transparent plastic sheet 5
Goes out from the transparent plastic sheet feed section 26
It is sent to the embossing section through 27 and the preheater 28. With the transparent plastic sheet 5 superposed on the pattern printing layer 3 surface provided on the transfer sheet 1, the embossing roll 23 is brought into contact with the transparent plastic sheet 5 surface so that the pressure roll 22 and the embossing roll 23 are connected to each other. By passing it, the pattern printing layer 3 is transferred to one surface of the transparent plastic sheet 5, and at the same time, the other surface of the transparent plastic sheet 5 is embossed. Pressure roll 22 and embossing roll
After passing between 23, the transfer sheet base material 2 is still laminated and cooled by the cooling roll 29 through the pitch mark detection device 24 and then rolled up by the processed sheet winding section 30 to form a transparent plastic sheet. Transfer of the pattern print layer 3 to 5 and embossing synchronized with the pattern print layer 3 are completed.

In the above manufacturing method, the transfer of the pattern printing layer 3 to the transparent plastic sheet 5 and the embossing synchronized with the pattern printing layer 3 are completed, and after cooling by the cooling roll 29, the transfer sheet substrate 2 is transparent. Alternatively, the transparent plastic sheet 5 may be peeled off from the plastic sheet 5 and wound, and only the transparent plastic sheet 5 on which the transfer and the picture pattern printing layer 3 are embossed is wound by the processed sheet winding section 30.

As shown in FIG. 1, the transfer sheet 1 used in the method for producing a decorative sheet according to the present invention has a transfer sheet 1a through a transfer sheet base 2 on which only a pattern printing layer 3 is provided. Is a colored resin layer 4 on the transfer sheet substrate 2.
Transfer sheet 1b on which a pattern printing layer 3 is formed
Used in either configuration. In the transfer sheet 1b, the colored resin layer 4 provided on the transfer sheet substrate 2 becomes a solid colored layer or a protective layer that covers the entire surface of the pattern printing layer 3 in a state where the pattern printing layer 3 is transferred to the transparent plastic sheet 5. It is a thing. The thickness of the colored resin layer 4 can be arbitrarily set within a range in which it can be applied by printing or coating. When the thickness of the colored resin layer 4 is increased to 20 to 40 μm, after the transfer of the pattern printing layer 3 to the transparent plastic sheet 5 and the embossing synchronized with the pattern printing layer 3 are completed,
It is not necessary to stack the colored plastic sheet 6 for protecting the pattern print layer 3.

When the colored resin layer 4 is provided by printing by the gravure printing method simultaneously with the pattern printing layer 3, the thickness of the colored resin layer 4 is preferably 3 to 10 μm. When increasing the thickness of the colored resin layer 4 to 20 to 40 microns, the colored resin layer 4 is first applied to the transfer sheet base material 2 by a method such as roll coating, and then the pattern printing layer 3 is formed by gravure printing. Should be provided.

As the transfer sheet substrate 2, a plastic film having excellent heat resistance and dimensional stability is suitable, and a polyethylene terephthalate film, a biaxially oriented polypropylene film or the like can be used, but a polyethylene terephthalate film of 25 to 48 microns Is the best.
The resin used for the pattern printing layer 3 to the colored resin layer 4 may be a resin having good adhesiveness to the transparent plastic sheet 5,
When a transparent polyvinyl chloride sheet is used as the transparent plastic sheet 5, a printing ink made of a vinyl chloride resin or a coating liquid made of a vinyl chloride resin is used. The coloring density of the colored resin layer 4 can be arbitrarily set in relation to the thickness of the colored resin layer 4 so as to be a density necessary for reproducing the grain design in the case of wood grain.

A pattern printing pitch in the pattern printing layer 3 of the transfer sheet 1 is printed smaller than the embossed pattern pitch, and a tension is applied to the transfer sheet 1 at the time of transfer to enlarge the pattern printed pitch to match the embossed pattern pitch. By transferring and embossing the printing layer 3,
The embossing synchronized with the pattern printing layer 3 becomes possible. The pattern printing pitch in the pattern printing layer 3 is preferably set to a smaller pattern printing pitch within the range of 0 to 0.5% than the embossed pattern pitch. Regarding the relationship between the pattern print width and the embossed pattern width, when the transfer sheet 1 is stretched by tensioning it, the pattern printed width naturally shrinks. Therefore, the width of the pattern printed layer 3 should be set larger than the embossed pattern width. I need to put it. The width of the pattern print layer 3 is 0 to 0.2% of the width of the embossed pattern.
It is better to set it larger. It is necessary to appropriately set the numerical values of the pattern print pitch and the pattern print width of the pattern print layer 3 provided on the transfer sheet 1 depending on the type and thickness of the transfer sheet substrate and the transfer / embossing conditions.

The pattern-printing pitch of the pattern-printing layer 3 provided on the transfer sheet 1 naturally varies when the pattern-printing layer 3 is printed on the transfer sheet base material 2. Therefore, the variation is reduced as much as possible. The average value of is preferably in the range of 0 to 0.5% smaller than the embossed pattern pitch as described above. When the pattern print layer 3 is provided on the transfer sheet 1, transparent pattern on both sides of the transfer sheet base material 2 where the pattern print layer 3 is not provided corresponds to a pattern print pitch mark as shown in FIG. Provide 11 The embossing roll 23 is provided with the embossed pattern pitch marks 12 on both flat portions without embossed patterns as shown in FIG. Although the shape of the pattern print pitch mark 11 and the embossed pattern pitch mark 12 is arbitrary, a rectangular shape is preferable as shown in FIG. The embossed pattern pitch mark 12 is preferably made so that when the mark is embossed, the embossed portion is formed into fine unevenness and becomes opaque.

[0018] In a state where the embossing is perfectly synchronized with the pattern printing layer 3, the pattern printing pitch mark 11 of the transferred pattern printing layer 3 and the embossed pattern pitch mark 12 embossed.
The relative positional relationship between the two may be any of a state in which they are completely overlapped with each other, a state in which they are adjacent to each other, and a state in which they are arranged at a certain distance. It suffices that the relative positions of both the pattern printing pitch mark 11 and the embossed pattern pitch mark 12 can be accurately detected by the transmitted light or the reflected light in the pitch mark detection device 24. In FIG. 6, the positions of both marks in a state where the emboss is perfectly aligned with the pattern print layer 3 are set to be in a state of being arranged at a constant interval. In FIG. 6, when the emboss is not in tune with the pattern print layer 3, the relative positions of both the pattern print pitch mark 11 and the emboss pattern pitch mark 12 are displaced. In that case, the pitch mark detection device 24 detects the distance between the two marks and transmits the information to the tension control device 25. Tension control device
In accordance with 25, the tension of the transfer sheet 1 is adjusted based on the above information so that both marks come to the predetermined positions, so that the pattern printing layer 3 and the emboss can be perfectly synchronized.

As a method of adjusting the tension, as in the tension control device 25 shown in FIG. 1, the feed speed of the transfer sheet 1 is adjusted by the driving roll, so that the difference in peripheral speed between the embossing roll 23 and the driven embossing roll 23 is obtained. The tension of the transfer sheet 1 may be adjusted by adjusting the tension of the transfer sheet 1 by adjusting the brake of the transfer sheet feeding section 21. Since the pattern print pitch must be accurately aligned with the embossed pattern pitch by adjusting the tension of the transfer sheet 1, a precise tension control device is required.

3 (a) and 3 (b), the transfer sheet substrate 2 is peeled off after the pattern printing layer 3 produced by the production method of the present invention shown in FIG. The layer structure in the state shown in (a) is transferred by the transfer sheet 1a having only the pattern printing layer 3 (a).
Is transferred using a transfer sheet 1b having a pattern printing layer 3 and a colored resin layer 4. In the case of the configuration of FIG. 3A, the embossing and the pattern printing in which the colored plastic sheet 6 is laminated on the surface of the pattern printing layer 3 and the colored plastic sheet 6 is laminated on the surface of the pattern printing layer 3 shown in FIG. The decorative sheet is in line with the layer 3. When the colored resin layer 4 is thick in the configuration of FIG. 3B, the decorative sheet is used as it is. After the transfer of the pattern print layer 3, the embossing in synchronization with the pattern print layer 3, the lamination of the colored plastic sheet 6 and the like are completed, the embossed recesses 8 of the transparent plastic sheet 5 are filled with the wiping ink 9 and the surface thereof is subjected to gloss adjustment. The layer 7 is provided to complete the embossed transfer sheet in synchronization with the pattern printing layer 3.

In the method for producing a decorative sheet of the present invention,
It is also possible to manufacture by the manufacturing method shown in FIG. In the above method, the transfer sheet 1 is transferred to the transfer sheet feeding section 21.
It goes out and is sent to the embossing section through the tension control device 25. On the other hand, the transparent plastic sheet 5 exits from the transparent plastic sheet feeding unit 26, passes through the preheating drum 27 and the preheating heater 28, and is sent to the embossing unit. With the transparent plastic sheet 5 superposed on the surface of the pattern printing layer 3 provided on the transfer sheet 1, the transparent plastic sheet 5
Press the embossing roll 23 in contact with the surface
By passing between 32 and the embossing roll 23, the pattern printing layer 3 is transferred to one surface of the transparent plastic sheet 5, and at the same time, the other surface of the transparent plastic sheet 5 is embossed. Up to this point, the method is the same as that in FIG. Immediately after the transfer and embossing are completed, the transfer sheet base material 2 is peeled off and wound up on the transfer base material sheet winding section 33. On the other hand, on the transfer surface of the pattern printing layer 3 of the transparent plastic sheet 5 from which the transfer sheet base material 2 has been peeled off, a colored plastic sheet feeding section is provided.
The colored plastic sheets 6 coming out of 31 are superposed and passed between the pressure roll 32 and the embossing roll 23, whereby the colored plastic sheet 6 is laminated on the surface of the pattern printing layer 3 of the transparent plastic sheet 5, and the pitch mark detecting device is provided. After being cooled by the cooling roll 29 via 24, it is wound by the processed sheet winding unit 30.

Example 1 A polyethylene terephthalate film having a thickness of 38 μm was provided with a coloring resin layer made of polyvinyl chloride resin having a thickness of 30 μm by a roll coating method, and a grain was formed on the surface of the coloring resin layer by gravure printing. A pattern printing layer was provided. The average value of the pattern print pitch of the pattern print layer was 0.3% smaller than the embossed pattern pitch, and the pattern printed width was printed 0.2% larger than the embossed pattern width to prepare a transfer sheet. Using the above transfer sheet, a transparent polyvinyl chloride sheet having a thickness of 0.12 mm, a preheating drum temperature of 165 ° C., a Teflon pressure roll temperature of 170 ° C., an embossing roll temperature of 60
The pattern print layer was transferred at the same time under the conditions of ° C, a nap pressure of 25 kg / cm ² , and a speed of 10 m / min, and at the same time, wood grain pattern embossing was applied to the pattern print layer. At that time, the pitch mark detection device detects the relative positions of the printed pattern pitch mark and the embossed pattern pitch mark transferred or embossed on the transparent polyvinyl chloride sheet, and the tension control device based on the information from the pitch mark detection device. By adjusting the tension of the transfer sheet, it was possible to stably apply wood grain embossing in synchronization with the wood grain pattern printing layer. After transferring the wood grain pattern printing layer to the transparent polyvinyl chloride sheet and simultaneously applying the wood grain pattern embossing in synchronization with the pattern printing layer, it was cooled and temporarily wound while the transfer sheet substrate was laminated. In a separate process, the transfer sheet base material is peeled off and removed, the embossed surface of the transparent polyvinyl chloride sheet is wiped, a gloss adjustment layer is provided, and the wood grain conduit embossed in synchronization with the wood grain pattern printing layer is applied to the natural wood grain. It was possible to continuously and stably manufacture a decorative sheet having an excellent design property close to the above.

Example 2 A polyethylene terephthalate film having a thickness of 38 μm was provided with a colored solid printing layer of a polyvinyl chloride resin having a thickness of 5 μm by a gravure printing method, and a wood grain pattern printing layer was provided thereon. The pattern print pitch and the pattern print width of the pattern print layer of the transfer sheet were set in the same manner as in Example 1. Using the above transfer sheet, a 120 μm thick transparent polyvinyl chloride sheet was transferred under the same conditions as in Example 1 while simultaneously transferring the pattern print layer and embossing a wood grain pattern in synchronism with the pattern print layer. By the method shown, while peeling and winding the transfer sheet substrate immediately after transfer and embossing,
Colored polyvinyl chloride sheet A 70-micron-thick colored polyvinyl chloride sheet fed from the paper feeding section is superposed on the transfer surfaces of the wood grain pattern layer and the colored solid printing layer of the transparent polyvinyl chloride sheet, and by the above transfer and embossing. Thermal lamination was performed between a Teflon pressure roll and an embossing roll, which were different from those used, and was wound up through a pitch mark detection device and a cooling roll. Also in this embodiment, as in the first embodiment, the relative positions of the transferred or embossed printed picture pitch mark and the embossed pattern pitch mark are detected by the pitch mark detection device, and the tension of the transfer sheet is adjusted by the tension control device to stabilize the printing. As a result, the wood grain embossing that matches the wood grain pattern printing layer could be applied. Then, the embossed surface of the transparent polyvinyl chloride sheet was wiped to provide a gloss adjusting layer, and
A decorative sheet having a design similar to that of a natural wood grain, which is embossed with a wood grain conduit in synchronism with the wood grain pattern printing layer, was manufactured.
