Lower release paper 2.

In FIGS. 1 to 9, only the thickness dimension is shown in an extremely enlarged manner in order to facilitate understanding of the sticker of the present invention.

(Returning to FIG. 1) The lower surface side of the upper release paper 1 and the lower surface side of the edge treatment protective film 3 are each an adhesive surface. That is, although not shown, a thin adhesive layer is formed on the lower surface side of the upper release paper 1 and the lower surface side of the protective film 3 for edge treatment, respectively.

The decal forming sheet body 4 comprises a decal forming sheet main body 8 and an adhesive layer 9 on the lower surface side thereof.
The lower surface is an adhesive surface.

Also, the edge processing form 5 includes a form body 10.
And a pressure-sensitive adhesive layer 11 on the lower surface side thereof, and the lower surface side is an adhesive surface like the decal forming sheet body 4.

The edge processing form 5 is disposed with an interval S having a predetermined width W _{2 from} the edge of the decal forming sheet body 4.

A sealing agent coating margin 12 having a predetermined width W ₁ is formed along the upper edge of the decal forming sheet body 4.

That is, when the decal forming sheet 4 and the edge processing protecting film 3 are adhered to each other, the edge processing protecting film 3 is formed near the outer peripheral edge of the decal forming sheet 4. is set to the shape and size may protrude to a predetermined width W ₁ only outward from the outer peripheral edge (see FIG. 10).

When actually forming the sealing agent coating margin 12, the decal forming sheet member 4 cut in a predetermined shape is attached to the edge processing protective film 3 cut in a predetermined shape in advance. good.

On the upper surface side of the lower release paper 2, the pressure-sensitive adhesive layer 11 of the edge processing form 5 and the pressure-sensitive adhesive layer 9 of the decal forming sheet body 4 are formed.
Has a smooth peeling surface so that it can be easily peeled off even if it has strong adhesive strength.

It is preferable that the material of the upper release paper 1, the lower release paper 2, the protective film 3 for edge processing, and the material of the form frame 5 for edge processing be resin, paper, or the like. It is desirable that the material of the decal forming sheet member 4 be a resin or the like having a high durability against wind, rain, and sunshine.

It is desirable that the upper release paper 1 is transparent so that the position and shape of the decal forming sheet body 4 can be easily checked.

Next, the decal forming method of the present invention will be described in the order of steps.

First, while releasing the lower release paper 2 of the sticker shown in FIG. 1 from the decal forming sheet body 4 and the edge processing form 5, the decal forming sheet body 4 and the edge processing form 5 are removed from the upper release paper. In a state of being fixed to the lower surface side of 1, the decal forming sheet body 4 and the edge processing formwork 5 are adhered to the adhered surface 13 which is the outer surface of an aircraft or a vehicle shown in FIG.

More specifically, while gradually releasing the lower release paper 2 from the end, the upper release paper 1 at the released portion is pressed down from the upper surface side using a spatula so as to prevent air bubbles from entering, and is sequentially adhered.

Immediately before the application, dust, dust, oils and fats, etc., adhering to the surface 13 to be attached are completely removed in order to improve the adhesive force.

Further, in order to make it easy to peel off only the lower release paper 2, the adhesive force between the decal forming sheet body 4 and the edge processing form 5 and the lower release paper 2 is determined by the adhesive force of the other adhesive surface. It is set weaker than

In this way, as shown in FIG. 2, the decal forming sheet body 4 and the edge processing form 5 are fixed to the lower surface side of the release paper 1 and adhered to the surface 13 to be adhered.

Thus, the decal forming sheet 4 and the edge processing form 5 can be simultaneously and easily adhered to each other, and the predetermined width of the space S between the decal forming sheet 4 and the edge processing form 5 can be improved. it can be held dimension W ₂ constant.

Therefore, there is no need to attach a tape corresponding to the edge processing formwork 5 which has been a problem in the prior art.

After that, the upper release paper 1 is separated from the edge processing protective film 3 and the edge processing mold 5, and as shown in FIG. 3, the decal forming sheet body 4 and the edge processing protective film 3 on the upper surface side thereof. And the edge processing form 5 are left on the surface 13 to be adhered.

Thus, the surface to be adhered corresponding to the interval S between the decal forming sheet body 4 and the edge processing formwork 5 is formed.
An exposure slit portion 14 exposing 13 is formed.

Next, the sealant coating margin 12 of the decal forming sheet body 4 and the adhered surface exposed corresponding to the interval S

As the sealing agent 15, it is preferable to use a transparent resin-based sealing agent in order to make the finish more beautiful. It is also possible to use a translucent or non-transparent sealing agent.

Thereafter, as shown in FIG. 5, the protective film 3 for edge treatment is detached from the decal forming sheet body 4 and the formwork 5 for edge treatment is detached from the surface 13 to be adhered.

In order to prevent the sealing agent 15 from peeling off, the separation of the protective film 3 for edge treatment and the formwork 5 for edge treatment from the surface 13 to be adhered is performed before the sealing agent 15 is dried. Is desirable. In order to prevent the edge processing form 5 from remaining on the surface 13 to be adhered, the edge processing form 5
Is desirably released as soon as possible after sticking to the sticking surface 13.

Further, in order to facilitate peeling of the edge processing protective film 3, the adhesive force between the edge processing protective film 3 and the decal forming sheet body 4 is set to a value between the decal forming sheet body 4 and the adhered surface 13. It is set smaller than the sticking force between the two.

Finally, it is confirmed that the decal forming sheet 4 and the sealing agent 15 are completely stuck on the surface 13 to be stuck, and the decal formation is completed.

In this way, the sealing agent 15 is attached along the outer peripheral edge of the decal forming sheet body 4 stuck to the surface 13 to be adhered, and a decal is formed on the surface 13 to be adhered.

[0042] Thus, At a decal which is formed as described above, the width of the sealing agent 15, a predetermined width dimension W ₁ of the sealing agent coating margin 12 with a predetermined width W ₂ of the interval portion S of the above Will be equal to the sum of

Accordingly, the width of the sealing agent 15 can be made constant, and the edges on both sides of the sealing agent 15 can be prevented from irregularly meandering. For this reason, the decal is neatly trimmed by the sealing agent 15, and a beautiful finish can be obtained.

Further, since the sealing agent 15 can be easily and surely adhered, it is particularly suitable for a vehicle or an aircraft which is exposed to the wind and rain for a long time.
