Description

  The present invention relates to a synthetic resin laminated sheet that can be used for, for example, posting, advertisement, guidance, decoration, etc., as well as materials for daily necessities and learning materials. More specifically, the present invention relates to a synthetic resin laminated sheet having a magnetic material. Regarding the sheet.

  Adsorbed sheets and magnetic sheets having a magnetic material are used in various ways. For example, in the case of an adsorbed sheet having a non-magnetized magnetic material that is not magnetized, use as a material for a bulletin board, wallpaper, or the like has been proposed. As such a thing, there exists what was disclosed by the following patent documents 1, 2, 3, and 4. FIG.

  The magnetic material of these adsorbed sheets is composed of powder and mixed with paint and applied to the sheet material (see Patent Documents 3 and 4), or composed of metal foil and attached to the sheet material. (See Patent Documents 1 and 2), and is applied in a layered manner to a part of the adsorbed sheet. However, since it is configured as described above, the layer having the magnetic material is thin, and the force attracted to the magnet is weak.

  In the case of a magnet sheet having a magnetized magnetic material, it is used by being attached to a place where a magnet such as a bulletin board or a car body can be adsorbed for displaying advertisements or the like. Examples of this include those disclosed in Patent Documents 5 and 6 below.

  The magnetic material of these magnet sheets is composed of a powdery material, mixed with a synthetic resin, formed into a sheet shape, and applied as a magnet layer to a part of the magnet sheet.

  In this magnetic sheet, it is desirable to have a strong magnetic force because other magnetic materials must be adsorbed to maintain the adsorbed state, but at least in order to be able to perform printing for displaying advertisements, etc. It is necessary to have a predetermined thickness or less. For this reason, there is a limit in increasing the magnetic force by increasing the thickness of the magnet layer having the magnetic material. On the other hand, the magnet sheet needs to be light in order to obtain an attractive force without diminishing the magnetic force that is difficult to increase. However, in order to enable beautiful printing, the thickness of the portion to be printed is also required to some extent.

  It is difficult to realize such contradictory requirements, and the applicant has not been satisfied with the magnet sheet disclosed in Patent Documents 5 and 6, but the present applicant has found such a problem. A magnetic sheet for a large-scale inkjet printer that can be solved (see Patent Document 7 below) has been proposed. This sheet is a magnetic sheet for outdoor advertising, which has a strong adsorptive power and enables beautiful printing. A printing layer comprising a 0.4 mm thick magnet layer and a 0.1 mm thick vinyl chloride It is what has.

JP 2001-166719 A JP 2005-274660 A Japanese Patent Laid-Open No. 11-272217 JP-A-9-1743 Japanese Patent Laid-Open No. 2004-29095 Japanese Patent No. 2848582 Registered Utility Model No. 3117937

  According to this magnet sheet, the intended purpose can be achieved and the practical value is high, but the opponent to which this magnet sheet is adsorbed is limited to hard parts such as bulletin boards and automobile bodies as in the above example. It was. This is because, as described above, the attracted sheet having the non-magnetized magnetic material cannot exert a strong attracting force.

  In particular, the attracted sheet having a magnetic material in a non-magnetized state is not versatile because its use is limited, for example, for posting. In the case where the adhesive layer is provided as in the above-mentioned Patent Document 1, the object that can be pasted is limited depending on the type of the adhesive, or it cannot be re-adhered, and the usage is limited. I could not.

  Therefore, the present invention is capable of adsorbing with a strong adsorbing force and capable of beautiful printing if necessary, and a versatile synthetic resin laminated sheet that can be used in various degrees of freedom as required, and its The main purpose is to provide usage.

  For this purpose, a magnetic layer containing a magnetic powder and made of a flexible synthetic resin and having a certain thickness is laminated on only one surface of the magnetic layer so that printing by a non-aqueous inkjet printer is possible. It is a synthetic resin laminated sheet made of a synthetic resin exhibiting white and made of only a print-allowing layer that is thinner than the magnetic layer and has flexibility.

  Examples of the ink of the non-aqueous sink jet printer include solvent ink (solvent ink), UV curable ink, and mu bio ink (environment-friendly ink).

  Magnetic nanoparticles are preferably used for the magnetic powder.

  The magnetic layer functions to be adsorbed by a magnet, to adsorb another member as a magnet, and to support a print permitting layer. On the other hand, the print-accepting layer functions to conceal the magnetic layer and to apply printing ink as necessary. The print-allowable layer is thinner than the magnetic layer, and the thickness of each layer is set so that each layer can perform a necessary function within a range in which printing by a non-aqueous inkjet printer is possible.

  Such a synthetic resin laminated sheet is used by performing desired printing on the print permitting layer as necessary, and appropriately cutting as necessary. If the magnetic layer is in a magnetized state, it can be fixed as it is to a bulletin board or an automobile body, and if the magnetic layer is in a non-magnetized state, it can be fixed as it is to a magnet sheet or the like. If necessary, it can be fixed to a wall surface, a glass surface or the like by applying an adhesive to the surface of the magnetic layer or the printable layer. It can also be used as a material for daily necessities and learning materials such as cutter mats, clay plates, drawing boards, game boards, educational materials, etc. by bonding them to hard sheet materials. The member to be bonded may be a flexible sheet material such as wallpaper.

  In particular, in addition to fixing to a wall surface or the like as described above, after printing on the print-allowable layer of the synthetic resin laminated sheet, the synthetic resin laminated sheet is stretched on both upper and lower ends of the synthetic resin laminated sheet. When the tension member is attached and stretched, the bulletin board function and the decoration function can be exhibited without damaging the wall surface. In this case, especially if it is attached to the wall of an exhibition booth such as an exhibition or trade show, the exhibition booth can be easily prepared and cleaned up, and the contents of the exhibition can be easily changed. You can avoid damaging the booth panel.

  As described above, according to the present invention, it is possible to perform adsorption by a strong adsorption force, and it is possible to perform beautiful printing if necessary. Moreover, since it consists only of a magnetic layer and a printing permissible layer, it becomes a versatile synthetic resin laminated sheet that can be used with various degrees of freedom as required.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a synthetic resin laminate sheet 11 and a partially enlarged sectional view showing a sectional structure thereof. As shown in this figure, the synthetic resin laminate sheet 11 has a flexibility that can be wound into a roll. The flexible sheet is formed of a magnetic layer 12 and a print-allowable layer 13 laminated on only one surface of the magnetic layer 12 and is formed to have a width of about 1000 mm suitable for printing with a large ink jet printer.

The magnetic layer 12 is made of synthetic resin having flexibility for containing the magnetic powder 12a, it is formed at a constant thickness t ₁ by calendering. An appropriate powder such as iron oxide can be used for the magnetic powder 12a. Of these, magnetic nanoparticles (MnZnFe ₂ O ₄ ) are preferably used. This is because it is finer than normal iron powder and can improve the adsorption power.

  As the synthetic resin including the magnetic powder 12a, a soft resin is used, and for example, chlorinated polyethylene is preferably used.

A test was conducted to show the fact that the use of magnetic nanoparticles (MnZnFe ₂ O ₄ ) as the magnetic powder 12a can improve the adsorptive power.
In order to examine the force with which the sheet made of only the magnetic layer 12 is attracted to the magnet, a test was performed using an apparatus 21 as shown in FIG. In the apparatus 21, 22 is a load cell, 23 is a weight meter, 24 is a magnet sheet, and 25 is an adsorbed sheet made of only the magnetic layer 12. The attracted sheet 25 was brought into close contact with the magnet sheet 24 and attracted thereto, and the force required to separate the attracted sheet 25 in this state from the magnet sheet 24 was measured.

For the adsorbed sheet 25, a sample 1 containing magnetic nanoparticles and a sample 2 containing iron powder were prepared. In either case, the thickness is 0.4 mm. As for the composition, Sample 1 contains 88.90% magnetic nanoparticles (MnZnFe ₂ O ₄ ), 8.53% chlorinated polyethylene, and 2.57% additive. On the other hand, Sample 2 contains 89% iron powder, 10% chlorinated polyethylene, and 1% additive. In addition, all are weight%.

  In the test, two types of magnet sheets 24 having the same composition and different thicknesses were used in order to observe the difference due to the difference in attraction force. This is because the attracting force of the magnet sheet 24 increases as the thickness increases.

  As a result, as shown in FIG. 2B, in any of the two types of magnet sheets 24 having different attractive forces, the sample 1 containing magnetic nanoparticles is more magnet than the sample 2 containing iron powder. The power attracted by was strong. Further, it can be seen that the higher the attractive force of the magnet sheet 24, the stronger the attractive force of the attracted sheet 25 is.

The print-allowable layer 13 is formed of a synthetic resin exhibiting a white color that can be printed by a non-aqueous inkjet printer. Vinyl chloride is used as the synthetic resin. PET (polyethylene terephthalate) or the like can also be used. The print-allowable layer 13 is formed to a constant thickness t ₂ by calendering, and the thickness t ₂ is thinner than the thickness t ₁ of the magnetic layer. Further, the surface does not have a coating layer for an ink receiving layer necessary for printing with a water-based ink jet printer, but fine irregularities are formed and the appearance is matte.

  The magnetic layer 12 and the print permitting layer 13 are bonded together by laminating (heat pressing). The magnetic layer 12 is in a non-magnetized state.

For printing with a large ink jet printer, it is preferable that the magnetic layer 12 and the print permitting layer 13 are combined to 0.5 mm. Specifically, the thickness t ₁ of the magnetic layer 12 is 0.4 mm. the permissible layer thickness _{t 2} it is preferable to 0.1 mm.

  The synthetic resin laminated sheet 11 configured in this way is printed on the print-allowable layer 13 as shown in FIG. 3A, or separated from the magnetic layer 12 as shown in FIG. 3B. The sheet material 14 is affixed, or a separate sheet material 14 is affixed to the print permitting layer 13 as shown in FIG. 3C, or the sheet material 14 is appropriately cut without being used. In FIG. 3A, reference numeral 15 denotes ink.

First, printing on the print-allowable layer 13 will be described (see FIG. 3A).
FIG. 4 shows a schematic configuration of a solvent-based large-sized inkjet printer 21 (hereinafter referred to as a printer).

  The printer 21 feeds the synthetic resin laminated sheet 11 wound in a roll shape onto the conveying surface 24 with a pair of feed rollers 22 and 23, and performs printing with a print head 25 disposed above the conveying surface 24 while being conveyed horizontally. After performing and printing, the synthetic resin laminated sheet 11 is sent out. Heaters 27 and 28 are provided at positions corresponding to the print head 25 below the receiving plate 26 provided on the entrance side and below the conveying surface 24, and the synthetic resin laminated sheet 11 is heated to fix the solvent ink. Configured to perform well. In the figure, reference numeral 29 denotes a receiving plate provided on the outlet side.

  As shown in FIG. 5, the distance H1 between the transport surface 24 and the print head 25 is set to about 2 mm in a general printer. For this reason, when the synthetic resin laminated sheet 11 having a thickness of 0.5 mm as described above is conveyed, a gap H <b> 2 of about 1.5 mm remains between the print head 25.

  Although the synthetic resin laminate sheet 11 is loosened by the heating by the heaters 27 and 28 and is deformed to float, the synthetic resin laminate sheet 11 never lifts by 1.5 mm, and the synthetic resin laminate sheet 11 is not caught during the conveyance. For this reason, it is not necessary to adjust the height of the print head 25, and the printing operation can be easily performed.

  The synthetic resin laminated sheet 11 receives ink ejected from the print head 25 while being conveyed, and a print display is formed. At this time, since the distance between the print head 25 and the print permitting layer 13 is not too far away, the ink can be fixed well as desired, and a clear print display can be obtained. The fixability of the ink can also be improved by the matte surface of the print permitting layer 13.

  Further, it is not necessary to change the temperature settings of the heaters 27 and 28 in accordance with the synthetic resin laminated sheet 11 during printing. That is, since the synthetic resin laminated sheet 11 is not as thick as 0.8 mm or 1 mm but 0.5 mm, the heat conduction from the heaters 27 and 28 is good, and the drying property and fixing property of ink. This is because printing unevenness does not occur.

  Ideally, the adjustment of the height of the print head 25 and the change of the temperature setting of the heaters 27 and 28 should not be performed because the operation is very complicated in consideration of the next printing on another type of printing sheet. Is. In this regard, if the synthetic resin laminate sheet 11 is used, it is not necessary to change them, so that the printing operation is easy. If the thickness of the synthetic resin laminated sheet 11 exceeds 0.5 mm, the advantage cannot be obtained.

  In addition, since solvent ink is used for the ink, shrinkage of the print-allowable layer occurs when drying after the printing is finished, but the 0.4 mm-thick magnetic layer 12 supports the print-allowable layer 13 firmly and firmly. The print-allowable layer 13 is also 0.1 mm, and has a sufficient thickness as compared with 10 μm, which is the thickness at which the ink penetrates the print-allowable layer 13, so that the shrinkage more than necessary can be suppressed. For this reason, generation | occurrence | production of the inferior goods by shrinkage | contraction can be eliminated and the printed display of desired size can be obtained. Since there is no shrinkage and print display of a desired size is obtained, when the synthetic resin laminated sheets 11 that have been divided and output are seamed together to form a large synthetic resin laminated sheet, there will be no deviation in the printed display.

  And since the magnetic layer 12 is formed with a relatively large thickness of 0.4 mm, the force attracted to the magnet is strong in combination with the use of the magnetic nanoparticles as described above. In addition, due to the unique thickness, there is no difficulty in manufacturing, and it can be produced at a low price, and the price can be reduced. The price reduction can also be realized by reducing the cost because the printing allowable layer 13 is made of vinyl chloride having no ink receiving layer on the surface.

  Moreover, since the magnetic layer 12 is 0.4 mm thick, the weight of the synthetic resin laminated sheet 11 can be suppressed. As a result, it is possible to prevent a load on the transport device of the printer 21 during transport during printing and to prevent a speed difference during transport. For this reason, it is possible to prevent a deviation between the initial print display and the final print display. Since there is no deviation in the printed display, there is no problem even when the synthetic resin laminated sheets 11 that are divided and output are seamed together, and a beautiful large synthetic resin laminated sheet with the printed display can be obtained.

  Next, sticking a separate sheet material 14 to the magnetic layer 12 and sticking a separate sheet material 14 to the print-allowable layer 13 will be described (see FIGS. 3B and 3C).

  The separate sheet material 14 may be of a size that covers the entire surface of the magnetic layer 12 or the print-allowable layer 13 or may be a size that covers a part of the magnetic material. In the former case, an existing sheet such as a film (whiteboard film) or wallpaper that can be erased by a marker, or a printed sheet printed on a favorite medium. In the latter case, a cut character or There are seals. It can be attached by an appropriate means such as adhesion with an adhesive or lamination (thermocompression bonding).

  Finally, it will be described how to cut and use as appropriate without doing anything.

  Since the synthetic resin laminated sheet 11 is made of flexible and soft synthetic resin as described above, it can be easily cut and cut with a cutter or the like. After cutting / cutting, it is possible to enter prints, characters, drawings, and the like on the print permission layer 13.

Next, the usage method of the above synthetic resin laminated sheets 11 is demonstrated.
First, a method of using it in the form of a so-called banner or tapestry will be described. In order to use as such, a tensioning member for tensioning the synthetic resin laminated sheet 11 is attached to the upper and lower ends of the synthetic resin laminated sheet 11 so that the synthetic resin laminated sheet 11 can be tensioned.

  FIG. 6 shows a usage state as the banner 41, and the banner 41 includes the synthetic resin laminated sheet 11 and the banner stand 32. First, a desired display content is printed on the synthetic resin laminated sheet 11 on the print permitting layer 13 thereof, and then the eyelets 31 as the tension members are fixed to the four corners.

  After that, if the existing banner stand 32 is used and the eyelet 31 is inserted and stretched on the hook 32a of the stand 32, the printed content is displayed and transmitted, and is attracted to the magnet or the magnet sheet 16. Banner 41.

  FIG. 7 shows the state of use in the form of a tapestry 42, which is composed of the synthetic resin laminated sheet 11 and the bar 33. For the synthetic resin laminated sheet 11, first, as shown in FIG. 6, the display content is printed on the print permitting layer 13, and then the bar 33 as the tension member is placed on the upper and lower ends. Secure to the edge. An existing bar 33 can be used as appropriate. The bar 33 is attached to an appropriate place by being suspended using an insertion hole 33a provided on the upper end surface. Attachment with a string may be used instead of the insertion hole 33a.

  Thus, the synthetic resin laminated sheet 11 used in the form of the tapestry 42 can be used in various scenes. In particular, as shown in FIG. 8, the synthetic resin laminated sheet 11 may be used in an exhibition booth 34 at an exhibition or trade show. That is, the synthetic resin laminated sheet 11 is used by being attached to the surface of the panel 35 of the exhibition booth 34 so as to cover the surface.

  Since nailing and the like are prohibited at the exhibition booth 34, for example, a double-sided tape is used when a poster or a foam board is pasted. However, when the exhibition is finished and peeled off, the poster or the like is damaged by the double-sided tape, and the poster cannot be used again. For this reason, even when an exhibition or the like for exhibiting the same content is held at a plurality of venues, necessary posters or the like must be remade. In addition to this, it is necessary to pay close attention not to damage the panel 35, and there has been a difficulty that is not convenient.

  However, if the synthetic resin laminate sheet 11 of the present invention is used in the form of a tapestry, the preparation can be made by simply hanging the synthetic resin sheet 11 and attaching it to an available wall surface such as the surface of the panel 35 or the wall surface of the venue. Since it is good, preparation and clean-up can be done easily and quickly. In particular, there is a great merit because it is required to strictly observe the export after the exhibition.

  As shown in FIG. 8, for example, “Present products of our company”, “Company overview”, “Achievements”, etc. are printed in advance and updated at each exhibition. If the contents should be printed on the magnet sheet 16 and pasted on the synthetic resin laminated sheet 11, one synthetic resin laminated sheet 11 can be used continuously and wasteful. Absent. Moreover, even if it is a printed part, if the magnetic sheet 16 which has another printing content from the top is attached, a display content can also be changed and there is no waste also in this point.

  In addition, a pocket that can hold a sheet piece such as a leaflet or a service ticket can be fixed on the surface of the magnetic sheet, so that the way of display can be expanded.

  Until now, the panel 35 of the exhibition booth 34 was not covered with tapestry. This is because the main body sheet constituting the tapestry and banner is composed of cloth, tarpaulin, and thermal transfer sheet, and the display contents of the printed display once performed cannot be changed, for example, another member such as a pocket It seems that this was because it was inconvenient because it had to be sewn or glued when trying to attach it, but it was inevitable in the situation where such preconceptions dominate .

  However, in this respect, the tapestry 42 and the banner 41 using the synthetic resin laminated sheet 11 of the present invention can obtain various effects as described above, can be used very conveniently, and have high practical value. .

  In particular, since the magnetic layer 12 contains magnetic powder such as iron powder, it also has a flameproof effect. For this reason, when covering a wall surface etc. in an exhibition etc., it can be used conveniently.

  Furthermore, when the synthetic resin laminated sheet 11 is displayed in the form of a tapestry as described above, the width of the display method can be widened and the protrusion can be reduced to make the display more compact. For this reason, a spacious layout can be realized by effectively using the limited space, and an effective display is possible. In particular, at exhibitions where wheelchair users and cane users visit, smart exhibitions that can be seen with ease are required. Considering this point, it is possible to provide attentive services to visitors.

An example of such utilization will be described with reference to FIGS.
FIG. 9 and FIG. 10 show the synthetic resin laminated sheet 11 used in the form of a tapestry 42 displayed at a restaurant front, and the lunch menu is printed on the print-allowable layer 13.

  The synthetic resin laminate sheet 11 of FIG. 9 is configured such that the “today's service set meal” portion can be appropriately set every day. That is, on the synthetic resin laminated sheet 11, the “Today's service set meal” portion is left blank, and other set meal menus are printed and displayed on the other portions with their names, photos, and amounts. A plurality of magnet sheets 16 on which necessary contents to be pasted on the “Today's service set meal” portion are printed are attached. Since printing on the magnet sheet 16 can be easily performed, it can be easily handled according to the food of the day.

  The synthetic resin laminate sheet 11 of FIG. 10 is configured such that “today's recommendation” can be appropriately set from a set meal prepared in advance. That is, on the synthetic resin laminated sheet 11, all set meal menus are printed and displayed with their names, photos, and amounts. A frame-shaped magnet sheet 16a displaying "Recommend of the day" and a plurality of magnet sheets 16b displaying the amount of money are attached. For each day, a frame-shaped magnet sheet 16a is pasted so as to surround an appropriate set menu, and a correct amount of magnet sheet 16b is pasted on the printed amount.

  In addition to these, it is possible to print various designs on the print-allowable layer and use them for decorations and redesigns of shops and shopping streets. Printing in recent years can be done very beautifully and is effective for decoration. In addition, the work for that is also easy.

  In the example shown in FIGS. 6 to 10, the synthetic resin laminated sheet 11 is shown as an example in which the magnetic layer 12 is not magnetized. However, as shown in FIG. In addition, a magnetized magnetic layer 12 can be used. In this case, the synthetic resin laminate sheet 11 having the same configuration as the above-described synthetic resin laminate sheet 11 in which the magnetic layer 12 is not magnetized can be used as the attracted sheet 17 to be adsorbed.

  In FIG. 11, the arrows drawn with phantom lines are directed to the magnetized state. In addition to using the synthetic resin laminated sheet 11 having the same configuration as the synthetic resin laminated sheet 11 as an adsorbed sheet, an adsorbed sheet coated with metal powder or other adsorbed sheet attached with metal foil may be used. Good. The same applies to the examples shown below.

  Next, a method of using the tension member as described above without using it will be described.

  FIG. 12 shows a usage method in which, for example, an appropriate character or design is printed on the print-allowable layer 13 of the synthetic resin laminated sheet 11 and is pasted on a surface to be attached 36 such as a wall surface, a floor surface, or a ceiling surface. Yes. That is, after printing on the print permitting layer 13, the adhesive 18 suitable for the desired surface to be attached 36 is applied to the magnetic layer 12 and attached to the surface to be attached 36 such as a wall surface. In FIG. 12, 15 is ink.

  As described above, recent printing can be performed very beautifully, so that it can be displayed freely, and can be freely used for printing a pattern suitable for wallpaper or ceiling, for example, for guidance display. In addition, since the magnet sheet 16 can be attached, various displays and display contents can be changed, and a piece of paper or the like can be fixed with a pin.

  Moreover, since the adhesive 18 can be selected according to the property of the to-be-attached surface 36, such as a wall surface and a floor surface, a favorable fixed state is obtained. The adhesive 18 may be one having re-tackiness, and in this case, it is convenient for use when it is necessary to remove it.

  FIG. 13 illustrates a use in which a sheet material 14 such as wallpaper, a whiteboard film, a cork sheet, or a decorative film is pasted on the magnetic layer 12 of the synthetic resin laminated sheet 11 and is pasted on a surface to be pasted 36 such as a wall surface. Shows how. That is, after the desired sheet material 14 is attached to the magnetic layer 12, the adhesive 18 suitable for the desired attachment surface 36 is applied to the print permission layer 13 and attached to the attachment surface 36 such as a wall surface. . The adhesive 18 may be applied to the surface to be attached 36 for pasting.

  This method is suitable when the printing method as described above does not feel good, when the user wants to use the printer like a whiteboard, or when the desired color is not obtained by printing on the print permitting layer 13.

  In this case as well, the magnet sheet 16 can be pasted, but since the sheet is pasted from the sheet material 14 side, the distance to the magnetic layer 12 is larger than when the magnet sheet 16 is pasted from the print permitting layer 13 side. It can be shortened and strong adsorption is possible.

  Also in this case, since the adhesive 18 can be selected according to the properties of the wall surface or the like, a good fixed state can be obtained. As the adhesive 18, an adhesive having re-tackiness can be used.

  FIG. 14 shows a usage method in which characters or patterns are printed for advertisements or pasted on the print-allowable layer 13 of the synthetic resin sheet 11 and pasted on a glass surface 36a of a building or a car. Is shown. That is, as shown in FIG. 14 (a), after a desired print indication is made on the print-allowable layer 13, a transparent adhesive 18 suitable for fixing to the glass surface 36a is applied to the print-allowable layer 13, and the glass Affixed to the surface 36a.

  According to such a method of use, advertisements to the outside can be easily performed using glass such as windows, and functions such as blindfolding can be provided. If the adhesive 18 has re-tackiness, it can be used temporarily.

  As shown in FIG. 14B, when the surface layer portion 19 is formed by pasting a sheet material 14 such as wallpaper or erasable film on the magnetic layer 12 or printing an appropriate pattern or the like. In the room, practical use such as decoration, posting, and sticking of the magnet sheet 16 is also possible.

  Next, a method for using as a material for daily necessities and learning materials will be described.

  FIG. 15A is a perspective view of a cork board-like bulletin board 45 that can use a push pin 51 in addition to a magnet and a magnet sheet 16, and FIG. 15B is a partial cross-sectional view thereof.

  The bulletin board 45 includes the frame material 45a, and the synthetic resin laminated sheet 11 and the support plate 45b which are housed inside and form a layer shape. Both the frame member 45a and the support plate 45b are made of appropriate materials. In the synthetic resin laminated sheet 11, a cork pattern is printed on the print-allowable layer 13 with non-aqueous ink.

  In such a bulletin board 45, by printing on the print permitting layer 13, the appearance looks like a cork, and the push pin 51 can actually be used like a cork board. Moreover, a magnet or magnet sheet 16 can be attached. For this reason, it can be used in a wider range than the cork board. Moreover, since the print permitting layer 13 is made of a synthetic resin, it is not broken like a cork and can be used in a beautiful state.

  FIG. 16 is a perspective view of a bulletin board 45 that can be used like a white board. As shown in a partially enlarged sectional view, the bulletin board 45 is composed of the synthetic resin laminated sheet 11 and the softness of the synthetic resin laminated sheet 11. The support plate 45b is made up of a suitable strength by compensating for the above. The support plate 45b may be composed of an appropriate synthetic resin plate or the like. Further, a whiteboard film 14 a is laminated on the print permitting layer 13 of the synthetic resin laminated sheet 11.

  The bulletin board 45 can be used by being hung at an appropriate place by a string 45c as shown by an imaginary line, for example.
