JPH0558392U - Correction tape or sheet - Google Patents

Abstract

(57) [Summary] [Purpose] In a correction tape or sheet to be affixed to corrections and corrections in documents, etc., make sure that the corrections, etc. are shielded so that the tapes, etc. do not appear when copying. To do. [Structure] A colorant layer and an adhesive layer are sequentially formed on a sheet-shaped base material such as paper, and a barrier layer is further formed between the base material and the colorant layer. [Advantageous effects] The colorant layer surely hides the characters in the correction area, and the barrier layer prevents the color transfer from the colorant layer to the base material to maintain the color tone of the base material, and also anchors the base material. To ensure that the bonding state between the tape layers is maintained.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a correction tape or sheet for correcting a document or affixing it to a correction portion.

[0002]

[Prior Art]

 Conventionally, correction fluids and tapes have been used to correct or correct documents written with ink or printed by various printers. Of these, the correction fluid is a paint-like substance consisting of a white pigment and resin, and in use, the correction area is painted over with a brush. There is a problem that it is extremely chewy, it is difficult to apply it uniformly and evenly, and it takes time to dry after application.

[0003] On the other hand, tapes are extremely simple methods because they can be left attached to the correction area as they are, or they can be attached once and then peeled off again. ) Is thin, there is a problem that the corrected part can be seen through. In order to prevent this see-through, it is recommended to increase the thickness of the above-mentioned base material, but when copying is performed with a dry copying machine etc., the outer peripheral edge of the tape appears black as a line ( There is a problem of (shadow of copy).

[0004]

[Problems to be solved by the device]

 Therefore, it is possible to hide the correction portion or the unnecessary portion temporarily or reliably for a long time, and to obtain a correction tape or sheet that does not have the shadow of the above copy. ..

[0005]

[Means for Solving the Problems]

 According to the present invention, a colorant layer is provided between a tape or sheet base material and an adhesive layer, and a barrier layer is further provided between the base material and the colorant layer. The object is to improve the concealing property to a portion, block the influence of the colorant layer on the base material, and obtain a good correction tape or the like which does not cause a shadow of copy.

【Example】

 Examples will be described below. A barrier layer 2, a colorant layer 3, and a pressure-sensitive adhesive layer 4 are sequentially formed on one side of a sheet-shaped substrate 1. As the above-mentioned substrate 1, usually paper is used, and particularly high-quality paper can be preferably used, and a thin paper of about 55 kg can be used, and even if it is slightly colored, when copied. Anything that does not appear in can be used.

The barrier layer 2 is formed by applying a mixture of a vehicle resin and a white pigment such as titanium white, and the one shown in the figure uses a vinyl chloride-vinyl acetate resin as the above resin, and is a very thin layer. Is forming. The colorant layer 3 is obtained by adding a colorant to the composition forming the barrier layer, and the color is preferably purple, blue or green, and ink pigments or dyes may be used. .. The barrier layer and the coloring agent layer can be formed on the substrate by coating, printing, transferring, spraying or other methods.

For the above-mentioned pressure-sensitive adhesive layer, various kinds of pressure-sensitive adhesives such as acrylic type, rubber type and the like can be used when the tape is left attached to the corrected portion. Further, in the case of being peeled again after being attached, various removable pressure-sensitive adhesives can be used, but the use of acrylic pressure-sensitive adhesive spherical fine particles gives a more preferable one. It is advisable to use these pressure-sensitive adhesives without adding a colorant and without coloring them. Moreover, when this is formed into a tape shape, it is advisable to provide a back surface treatment layer 5 for imparting releasability to the other surface of the base material 1.

When this is used, when the tape or sheet is pasted on the characters to be corrected or corrected, the correction portion is surely concealed by the presence of the colorant layer, and the colorant layer is Since the barrier layer is interposed between the base material and the base material, the color of the colorant layer is prevented from being transferred to the base material side and blocked, so that the base material retains its original color tone such as white. You can do this, and you won't see it or create shadows when you copy it. The basic composition of the colorant layer and the barrier layer is the same, and the vinyl chloride-vinyl acetate resin used for this has a good affinity with the above-mentioned high-quality paper and the releasable acrylic adhesive spherical particles. Since it is good, the anchoring action between the layers can be increased and the tape joint structure can be reliably retained. Moreover, since the thickness of the tape can be thinned as a whole, the shadow of the copy as described above does not occur. Furthermore, if it is re-peelable, it can be peeled off neatly without leaving an adhesive on the pasted part.

FIG. 2 shows the barrier layer 2 in which a vinylidene chloride resin layer 21 is formed on the base material 1 side in addition to the same barrier layer 22 as described above. The anchoring action of the colorant layer on the base material is increased to further improve the bonding state between the base material and each layer.

[0011]

[Effect of the device]

 As described above, according to the present invention, the portion to be corrected can be surely concealed, and the thickness of the tape or sheet as a whole is not thickened. Etc. can be effectively used.
