Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Technical Field] The present invention relates to a pressure-sensitive adhesive adhesive panel used for displaying photographs, bosses, etc., for example.

[Prior art] Conventionally, as an adhesive panel, a pressure-sensitive adhesive is provided on one entire surface of the base plate of a plastic foam board, and this pressure-sensitive adhesive is applied using release paper with marks placed on the outer surface at equal intervals vertically and horizontally. Covered adhesive panels are widely known.

This conventional pasting of photos, etc. to the pasting panel is usually performed in the following steps.

(1) Make a cut about 5B wide in the center of the adhesive panel and peel off the release paper from that part.

(2) Use the marks on the release paper to align the photo, etc., and temporarily secure it using the pressure-sensitive adhesive exposed in the center.

(3) Gradually peel off the release paper from one side at a time from the center cut and paste the photos, etc. together.

(4) After peeling off the release paper on both sides and pasting them together, cut off the excess portion of the adhesive panel.

[Problems to be Solved by the Invention] However, the above-mentioned conventional adhesive panels have the following problems.

(1) Those who are accustomed to making panels can finish it neatly by following the steps above, but those who are inexperienced may end up peeling off all the release paper first, making it impossible to utilize the marks on the release paper. I often fail.

(2) When pasting many small photographs etc. onto a single adhesive panel, it is necessary to remove all the release paper before pasting them together, and the marks on the release paper cannot be used. , it is difficult to align and adjust the orientation of photos, etc.

[Means for Solving the Problems] The means taken in the present invention to solve the above problems will be explained with reference to FIG. 1, which corresponds to an embodiment of the present invention. , marks 2 drawn at predetermined intervals in at least one vertical and horizontal direction or at least one diagonal direction, a pressure-sensitive adhesive 3 that covers the entire surface and allows the marks 2 to be seen through, and a release sheet 4 that covers the pressure-sensitive adhesive 3. This method takes the form of an adhesive panel in which the following are sequentially provided.

As the base plate 1 used in the present invention, a synthetic resin foam board is usually used. Examples of the synthetic resin foam board used for the base plate 1 include extruded polystyrene foam board, polystyrene bead foam board, polyvinyl chloride foam board, polyethylene foam board, polypropylene foam board, polymethyl methacrylate foam board, and polycarbonate foam board. Foamed boards and the like can be mentioned.

In order to make the synthetic resin foam board light and have the necessary strength, it is preferable that the foaming ratio is 5 to 40 times, particularly 7 to 20 times.

It is preferable that the surface of the synthetic resin foam board be as smooth as possible so that the surface of the bonded photograph, etc. does not become uneven. From this point of view, it is preferable that the synthetic resin foam board has a skin layer with a low expansion ratio (about 2 times) on the surface, rather than one with a cell layer exposed on the surface.

In order to provide the above-mentioned surface smoothness and also serve as reinforcement, a material obtained by laminating high quality paper such as art paper on the surface of a synthetic resin foam board can also be used as the base plate 1. Furthermore, in addition to the synthetic resin foam board, cardboard or a material in which high-quality paper such as art paper is laminated on the surface of cardboard can also be used as the base plate 1.

The thickness of the base plate 1 may be appropriately determined depending on the material and the like so as to obtain the necessary strength, but is usually about 3 to 10 mm.

The marks 2 need to be provided at predetermined intervals and at least in one direction vertically and horizontally or at least in one direction diagonally, and generally it is preferable to provide them in both the vertical and horizontal directions.

Note that the predetermined interval may be any interval having a certain regularity, such as an equal interval or a logarithmic interval, but is generally an equal interval.

The mark 2 is a flat mark, for example, a solid line, a dotted line, a chain line, etc., and can be provided by, for example, silk screen printing.

The color of the mark 2 is preferably one that is easy to see as an indicator, but it is preferably a slightly lighter color so that the mark 2 cannot be seen through the surface when a thin paper poster or the like is pasted.

Mark 2 may all have the same form and color, but
It is also possible to mix those with small intervals and those with large intervals by changing the shape or color.

The pressure sensitive adhesive 3 allows the mark 2 to be seen through from above, and is preferably as transparent as possible.

As the pressure-sensitive adhesive 3, for example, natural rubber-based, synthetic rubber-based, polyacrylic acid ester-based ones, etc. can be used.

The release sheet 4 may be general release paper made of paper coated with a printing agent such as silicone, synthetic resin film coated with a release agent, waxed paper or synthetic resin film, or pressure-sensitive paper. Depending on the type of adhesive 3, a polyethylene film or the like may be used.

[Function] In the present invention, providing the mark 2 directly on the base plate 1 serves to enable the mark 2 to be used for positioning even after the release sheet 4 is removed.

[Example] As shown in FIG. 1, this adhesive panel includes a base plate 1 having a mark 2 on its surface, and a pressure-sensitive adhesive that covers the entire surface of the base plate 1 where the mark 2 is provided. 3, and this pressure sensitive adhesive 3
It is composed of a peeling sheet 4 that covers the.

The marks 2 are solid lines printed in a checkerboard pattern on the surface of the base plate 1, and are provided at equal intervals vertically and horizontally, and are visible through the pressure-sensitive adhesive 3.

The base plate 1 is an extruded polystyrene foam board having a skin layer, and the release sheet 4 is an ordinary release paper.

FIG. 2 shows another embodiment of Mark 2, (a)
In the mark 2 shown in , dotted lines indicate small regular intervals, and solid lines indicate large regular intervals. In the mark 2 shown in (b), thin lines are formed at small constant intervals, and thick lines are formed at large constant intervals.

This makes it easier to understand the spacing and position, improving work efficiency. A similar effect can also be obtained by changing the color of the mark 2 depending on the interval.

Figure 3 shows another embodiment of this adhesive panel.
In addition to marks 2 similar to those shown in the figure, similar marks 2 are provided on the outer surface of the release sheet 4.

In this way, bonding can be performed using the same procedure as in the conventional method.

Although not shown, the mark 2 can be provided not only on the front side of the base plate 1 but also on the back side.

In this way, when the adhesive panel is cut into a desired size in advance, the cutting operation can be carried out using the mark 2 on the back side as an index while keeping the peeling sheet 4 attached. In addition, when the marks 2 are provided at multiple locations, as in the above case or the case explained in FIG. You can also select and use them. For example, the marks 2 on one side can be spaced in meters, and the marks 2 on the other side can be spaced in inches.

Note that the marks 2 may be provided on both sides, and both sides may be further covered with a pressure sensitive adhesive 3 and a release sheet 4.

[Effects of the Invention] The present invention is as described above, and has the following effects.

(1) By peeling off the release sheet 4, alignment using mark 2 will not become impossible. Regardless of whether you are used to making panels or not, you can use mark 2 for alignment, and there are fewer mistakes. "Become.

(2) Since the mark 2 can be used even when pasting many small photographs etc. onto a single pasting panel, workability in such cases is improved.
