Description

  The present invention relates to a pressure-sensitive transfer correction tape pancake in which the pressure-sensitive transfer correction tape does not deviate from the core when transported or incorporated in a transfer tool having an automatic winding mechanism.

  Conventionally, when erasing and correcting writing lines that cannot be erased with an eraser written with a ballpoint pen, fountain pen, sign pen, typewriter, etc. A pressure sensitive correction tape is provided. However, when such a typo is corrected with the correction liquid, there is a problem that it is difficult to rewrite and reprint the correction liquid because it takes a long time to dry and the correction portion is difficult to be smooth.

  In addition, a cassette-type pressure-sensitive transfer correction tape transfer tool having an automatic winding mechanism basically covers a cassette, a pressure-sensitive transfer correction tape supply reel and a take-up reel, and a pressure-sensitive transfer correction tape. And a head for pressing against the correction surface. When the transfer tool with an automatic take-up mechanism is moved while the head is pressed against the surface to be corrected, the pressure-sensitive transfer correction tape is fed out from the supply reel, and is sequentially pressed against the surface to be corrected by the head, and is bonded to the adhesive layer side. It will be done. On the other hand, after passing through the head, the support is separated from the pressure-sensitive transfer layer (a laminate of the correction coating layer and the adhesive layer) and wound on a take-up reel. When the transfer of the pressure-sensitive transfer layer to the corrected portion of the surface to be corrected is completed, when the transfer tool with an automatic winding mechanism is lifted after pressing the head strongly against the surface to be corrected, the pressure-sensitive transfer layer is cut, The corrective operation is complete. On the correction coating layer of the pressure-sensitive transfer layer transferred to the surface to be corrected, letters or the like can be written with a writing instrument such as a ballpoint pen.

The pressure-sensitive transfer correction tape is mainly wound around a paper tube or a plastic core to form a pressure-sensitive transfer correction tape pancake (hereinafter sometimes referred to as “pancake”) (Patent Document 1 or the like). .

  However, the pancake core and the pressure-sensitive transfer correction tape may loosen during storage or transportation of the pancake or when it is transported after being installed in a transfer tool with an automatic winding mechanism. In some cases, it cannot be incorporated into a transfer tool having an automatic winding mechanism. Further, when the pressure-sensitive transfer correction tape is displaced from the plastic core or the like in the state where it is incorporated in the transfer tool, the performance as the pressure-sensitive transfer correction tape cannot be sufficiently satisfied by contacting the supply reel or the like.

  The present invention, as a pancake, the pressure-sensitive transfer correction tape wound around a paper tube, a plastic core or the like does not deviate from the core before and after assembling to the pressure-sensitive transfer tool or during transportation after assembly. An object is to provide a pressure-sensitive transfer correction tape pancake.

  As a result of earnest research to solve the above-mentioned problems while sufficiently satisfying the performance as a pressure-sensitive transfer correction tape, the present inventors have made a core-side support to be bonded to a plastic film such as an aluminum vapor-deposited film. The present inventors have found that it is optimal to provide a portion having no pressure-sensitive transfer layer and to make the length of the portion 10% or more and 50% or less with respect to the outer peripheral length of the core.

  That is, the present invention provides a pressure-sensitive transfer correction tape having a pressure-sensitive transfer layer in which a correction coating layer and an adhesive layer are sequentially laminated on a support subjected to a release treatment, and the pressure-sensitive transfer layer is disposed outside. And a pressure-sensitive transfer correction tape pancake formed by winding the core around a roll through a bonding material composed of a plastic film and an adhesive tape. A pressure-sensitive transfer correction tape pancake is provided in which a portion not having a pressure-sensitive transfer layer corresponding to a length of 10% to 50% of the outer peripheral length of the core is formed.

  According to the present invention, while satisfying the performance as a pressure-sensitive transfer correction tape, the pressure-sensitive transfer correction tape wound around a paper tube or a plastic core is pre-assembled into a pressure-sensitive transfer tool, during assembly, and after assembly. It is possible to provide a pressure-sensitive transfer correction tape pancake that does not deviate from the core during transportation. Therefore, handling at the time of assembling is improved, and it is possible to prevent the pressure-sensitive transfer correction tape from being displaced from the core after assembling and coming into contact with the supply reel or the like of the pressure-sensitive transfer tool to cause a transfer failure or the like.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a state before the core of the pressure-sensitive transfer correction tape pancake according to the present invention is wound. In FIG. 1, reference numeral 2 denotes a support portion of the pressure-sensitive transfer correction tape that does not have a pressure-sensitive transfer layer, and the support has a release layer on both sides. 4 is a plastic film such as an aluminum vapor-deposited film, 5 is a core (core material for wrapping the tape), 3 is a pressure-sensitive adhesive tape which is a bonding material between the pressure-sensitive transfer correction tape and the plastic film and the film and the core. , 6 is a pressure-sensitive transfer correction tape (support + pressure-sensitive transfer layer) having a pressure-sensitive transfer layer. Reference numeral 1 denotes the length of the support portion having no pressure-sensitive transfer layer as defined in the present invention.

  In a pressure-sensitive transfer correction tape pancake, the pressure-sensitive transfer correction tape is bonded to the core by using a bonding material such as an adhesive tape and a plastic film. Further, when joining the pressure-sensitive transfer correction tape, the pressure-sensitive transfer layer (a laminate of the correction coating layer and the adhesive layer) is often removed for a certain length, and in the present invention, FIG. The length of the portion not having the pressure-sensitive transfer layer shown is 10% or more and 50% or less, preferably 10% or more and 40% or less, with respect to the outer peripheral length of the core used in the pressure-sensitive transfer correction tape pancake. When the specified length with respect to the outer peripheral length of the core is less than 10%, the pressure-sensitive transfer layer moves to the back surface of the support, or the working efficiency in producing the pressure-sensitive transfer correction tape pancake is significantly reduced. On the other hand, if it exceeds 50%, the supports on which the release layer is formed come into contact with each other and the holding force is reduced, so that the pressure-sensitive transfer correction tape is easily displaced from the core. By providing a portion having no pressure-sensitive transfer layer in the length of the above range, it is possible to prevent displacement of the pressure-sensitive transfer correction tape from the core.

  The pressure-sensitive transfer correction tape used in the present invention is formed by sequentially laminating a correction coating layer and an adhesive layer on a support subjected to a release treatment, and is not different from a conventional pressure-sensitive transfer correction tape.

  As a support body, plastic films, such as polyester films, such as a polyethylene terephthalate, polyolefin films, such as a polypropylene film and a polyethylene film, can be mentioned, for example. The thickness of the support is suitably in the range of 3 to 30 μm from the viewpoint of not impairing the function as a pressure-sensitive transfer correction tape.

  A release layer such as a silicone resin or a silicone resin in which an inorganic or organic pigment is dispersed is formed on one side or both sides of the support. Examples of the release agent used in the release layer include silicone resins, fluororesins, and waxes. In the release agent solution used for forming the release layer, an antigelling agent, an adhesion improver, and an antiblocking agent. Etc. may be added.

  The correction coating layer in the pressure-sensitive transfer correction tape of the present invention is not particularly limited, and is formed by applying a dispersion composed of a pigment having a hiding power, a polymer resin as a binder, and a solvent to a support, It is not different from the conventional pressure-sensitive transfer correction tape. Examples of the pigment having hiding power include rutile type and anatase type titanium dioxide, calcium carbonate, magnesium carbonate, magnesium silicate, polystyrene, silicon dioxide, alumina silicate, polymethacrylic acid ester, etc., but titanium dioxide is particularly preferable. Usually, an appropriate amount of a constitutional material is added to this. These pigments and polymer resin are mixed and dispersed in a solvent at a predetermined ratio to obtain a dispersion. The solvent may be either organic solvent-based or aqueous. In addition, various colorants, various additives, and the like can be appropriately selected and mixed in the dispersion as long as the object of the present invention is not impaired. The thickness of the correction coating layer is 5 to 30 μm, preferably 10 to 25 μm, in order to ensure the concealment property at the time of correction after drying.

  The pressure-sensitive adhesive layer in the pressure-sensitive transfer correction tape of the present invention is not particularly limited, and is formed by applying a pressure-sensitive adhesive by a conventionally known method. As the pressure-sensitive adhesive, for example, an acrylic resin-based, rosin-based, rubber-based, or vinyl-based pressure-sensitive adhesive can be used. These pressure-sensitive adhesives may be either solvent-based or water-based. The thickness of the adhesive layer is suitably about 0.3 to 5 μm, preferably about 0.5 to 1.5 μm after drying.

  Hereinafter, the present invention will be described more specifically with reference to Examples and Comparative Examples, but the present invention is not limited to only the following Examples.

(Examples 1-9 and Comparative Examples 1-5)
It tested using the support body from which thickness shown in Table 1 and a core (core material) from which a core diameter and a core outer periphery length differed. When processing pressure-sensitive transfer correction tapes into pancakes, various pressure-sensitive transfer corrections were made by removing the pressure-sensitive transfer layer to the length shown in Table 1 and changing the length without the pressure-sensitive transfer layer. Tape pancakes were produced, and the quality of work efficiency during production was evaluated according to the following criteria.

  In addition, in order to evaluate the deviation of the core of the obtained pressure-sensitive transfer correction tape pancake, instead of measuring the load when the pressure-sensitive transfer correction tape pancake is fixed and only the core is pressed, the pressure-sensitive transfer correction tape When the pancake ridges were fixed and only the core was pressed, the evaluation was performed based on the number of the cores that fell out of the pressure-sensitive transfer correction tape pancake.

(Workability)
○: The pressure-sensitive transfer layer can be peeled off and bonded as usual.
(Triangle | delta): The work time of pressure-sensitive transfer layer peeling and joining work becomes long.
X: Working time of pressure-sensitive transfer layer peeling / bonding operation is long and requires a technique.

(Vibration test)
○: All of the 10 pieces have no missing cores.
Δ: 1 to 7 out of 10 cores are missing.
X: 8 or more out of 10 pieces, and only the core is missing.

  The above evaluation results are summarized in Table 1. From the performance test results in Table 1, if the length of the support having no pressure-sensitive transfer layer is 10% or more and 50% or less with respect to the length of the outer periphery of the core, the working efficiency is good, and the paper tube or plastic core It can be seen that the pressure-sensitive transfer correction tape wound around the core does not deviate from the core before, during and after assembly to the pressure-sensitive transfer tool.

It is explanatory drawing explaining the pressure sensitive transfer correction tape pancake which concerns on this invention.
