Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive which is transferred onto a paper surface when, for example, paper is attached, and a pressure-sensitive adhesive transfer tool used for transferring the pressure-sensitive adhesive.

[0002]

2. Description of the Related Art Conventionally, when pasting a paper or the like, after the opening of a container containing an adhesive is brought into contact with a portion to be coated, the container is pressed to open the adhesive in the container. It is generally applied by extruding from. However, the method of applying the adhesive by pressing the container after abutting the opening of the container as described above has a problem that the adhesive cannot be applied uniformly.

Therefore, in order to solve the above problems,
Adhesive wound on the supply reel is applied to the surface of the tape, which is wound around the head exposed to the outside of the main body, and then wound on the take-up reel. There is provided a pressure-sensitive adhesive transfer tool capable of uniformly applying the pressure-sensitive adhesive by contacting and pressing the surface of the tape with the head and moving the same in a predetermined direction.

[0004]

By the way, since the pressure-sensitive adhesive applied with the above-mentioned pressure-sensitive adhesive transfer tool is colorless and transparent,
When a paper or the like is attached, there is a problem that it is difficult to confirm the applied adhesive and it is difficult to position the paper or the like.

Further, the above-mentioned pressure-sensitive adhesive transfer tool is inconvenient because the entire body is opaque and the amount of the pressure-sensitive adhesive remaining is unknown. Even if a transparent member is used for the main body, since the tape and the adhesive are both colorless and transparent, the remaining amount of the adhesive is difficult to discern at first glance. Further, there is no suitable method that can be distinguished at first glance to distinguish several kinds of tapes coated with adhesives having different adhesive strengths.

The present invention has been made in view of the above-mentioned problems, and it is possible to easily confirm the transfer position of the adhesive even after the application, the remaining amount of the adhesive, the adhesive strength, etc. It is an object of the present invention to provide a pressure-sensitive adhesive transfer tool capable of easily confirming.

[0007]

In order to achieve the above object, the pressure-sensitive adhesive of the present invention is applied to the surface of a resin tape with a predetermined thickness, and the surface of the tape is brought into contact with the application portion. In the pressure-sensitive adhesive that is transferred to the application portion by pressing from the back surface of the tape in this state, the organic pigment is mixed with the pressure-sensitive adhesive as a medium and colored.

Further, the pressure-sensitive adhesive transfer tool of the present invention comprises a supply reel on which the tape coated with the pressure-sensitive adhesive is wound, and a transparent main body for rotatably holding the supply reel inside.

The organic pigment is mixed in because the organic pigment does not melt in the solvent but exists as a molecule dispersed in the medium and does not affect the properties of the medium. Is. In addition, the organic pigment has a vivid color and is also excellent in chemical resistance and light resistance. Here, as the organic pigment, phthalocyanine-based pigments such as phthalocyanine blue, phthalocyanine green and fast sky blue, azo pigments such as brilliant carmine 6B, permanent yellow H10G, and lake red can be used.

[0010]

The pressure-sensitive adhesive of the present invention is applied to the surface of a resin tape with a predetermined thickness and transferred to the application portion by pressing from the back surface of the tape with the surface of the tape in contact with the application portion. In the adhesive, the organic pigment is mixed and colored using the adhesive as a medium, so that it is possible to easily confirm the transfer location of the adhesive.

The pressure-sensitive adhesive transfer tool of the present invention comprises a supply reel around which a tape coated with a colored pressure-sensitive adhesive is wound,
Since the transparent main body that rotatably holds the supply reel inside is provided, the adhesive present in the adhesive transfer tool can be visually confirmed.

EXAMPLE An example of the present invention will be described below. FIG. 1 is a view showing the constitution of an adhesive transfer tool used when applying the adhesive of the present invention.

In the drawing, reference numeral 1 designates a supply reel 3 around which a tape 2 having an adhesive applied on its surface is wound, and a take-up reel 4 around which a tape 2 after the transfer of the adhesive is wound are rotatably provided therein. The body of the pressure-sensitive adhesive transfer tool (hereinafter referred to as "main body")
It is). Then, the supply reel 3 and the take-up reel 4
The gear 6 formed on one side surface of the supply reel 3 and the gear 7 formed on one side surface of the take-up reel 4 mesh with each other so that the tape 2 wound around the supply reel 3 is rotated.
Is wound around a head 5 exposed to the outside of the main body 1, and then wound around a winding reel 4.

The pressure-sensitive adhesive of the present invention is obtained by mixing phthalocyanine blue, which is a phthalocyanine-based pigment, at a ratio of 0.03% by weight into the pressure-sensitive adhesive and coloring it in blue. It is applied to a predetermined place by a tool. By the way, this adhesive was applied in a layer of 20 μm in thickness to a 25 μm thick colorless and transparent polyethylene terephthalate (PET) tape surface to prepare an adhesive transfer tape, and the adhesive was applied to the paper. The pressure-sensitive adhesive thus obtained was also colored blue, and the adhesive strength was unchanged.

Also, when the azo pigment, Brilliant Carmine 6B, which is a soluble azo pigment, is mixed in an amount of 0.02% by weight and the adhesive is colored red, the adhesive applied to the paper is also red. It was colored and its adhesive strength did not change.

By mixing phthalocyanine green into the adhesive, the adhesive can be colored green. If the amount of the organic pigment mixed in the pressure-sensitive adhesive is within the range of 0.01% by weight to 0.05% by weight, the adhesive strength of the pressure-sensitive adhesive does not change. The color is so clear that the color cannot be seen through the paper.

Then, for example, a tape 2 in which phthalocyanine blue is mixed and a blue-colored adhesive is applied on the surface thereof is wound around a supply reel 3, and the main body 1 which rotatably holds the supply reel 3 therein is transparent. Then, the pressure-sensitive adhesive transfer tool shown in FIG. 1 is configured. The unused tape 2 wound around the supply reel 3 has a blue color due to the adhesive, and the used tape 2 wound around the take-up reel 4 is colorless and transparent. Therefore, by checking the blue tape 2 wound around the supply reel 3, the remaining amount of the adhesive can be known.

For example, for two kinds of adhesives having different adhesive strengths, one adhesive is mixed with phthalocyanine green to color the adhesive green, and the other adhesive is mixed with Brilliant Carmine 6B. Color the adhesive red. Then, two adhesive transfer tools in which the supply reel 3 around which the tape 2 having the respective adhesive applied on its surface is wound are housed in the transparent main body 1 are prepared. The adhesive strength of the adhesive can be distinguished by checking the color of the adhesive applied to the tape 2 of the supply reel 3 contained in these adhesive transfer tools.

When there are many adhesives having different adhesive strengths, each adhesive may be colored in a different color. Also,
When the width of the pressure-sensitive adhesive applied by changing the width of the tape 2 is changed, the pressure-sensitive adhesive applied on the tape 2 may be colored in different colors depending on the width of the tape 2.

[0020]

As described above, since the pressure-sensitive adhesive of the present invention is colored by mixing the organic pigment into the pressure-sensitive adhesive, the applied pressure-sensitive adhesive can be easily confirmed, and the position when sticking paper or the like Easy to match.

Further, the pressure-sensitive adhesive transfer tool of the present invention comprises a supply reel around which a tape coated with a colored pressure-sensitive adhesive is wound, and a transparent main body for rotatably holding the supply reel inside. The remaining amount of the pressure-sensitive adhesive can be easily confirmed by visually confirming the pressure-sensitive adhesive present in the pressure-sensitive adhesive transfer tool. Further, if the pressure-sensitive adhesive is colored in a different color depending on the strength of the pressure-sensitive adhesive strength, the width of the pressure-sensitive adhesive to be transferred, etc., the pressure-sensitive adhesive can be easily identified.
