  In the conventional correction member 110, the release layer 103 is provided on the support 102 by providing a release layer 103 on both sides of the support 102 (for example, by performing release treatment with silicone). While being held, the surface of the release layer 103 is peeled from the surface of the white hiding layer 105. Such “peeling” in which the surface of one layer and the surface of the other layer are peeled at the surface in contact with each other is called “interfacial peeling”, and a technique related to such “interfacial peeling” is common. ing. The reason why the technology related to this “interface peeling” is common is that, in the conventional correction member 110, the support 102 must be peeled from the interface of the release layer 103 while holding the release layer 103. This is because light peeling cannot be realized.

  However, in the conventional correction member 110, since the interface 102 peels from the white hiding layer 105 while the support 102 holds the release layer 103, the correction member 110 is cut or the white hiding layer is finished when the transfer is finished. There is a problem that the surface of 105 is peeled off, or the surface of the white hiding layer 105 is cracked.

  Further, in the conventional correction member 110, since the surface of the release layer 103 is peeled off from the surface of the white hiding layer 105 with the release layer 103 held on the support 102, the white hiding layer peeled off at the interface. There is a problem that the surface of the surface 105 becomes smooth and has a remarkably glossy appearance, and therefore, the surface of the white hiding layer 105 is glaring and the eyes are easily fatigued. Therefore, the surface of the white hiding layer 105 is made uneven by introducing fine particles into the silicone or making the surface of the white hiding layer 105 uneven by using a glassine paper having irregularities on the surface as the support 102. Although the glossiness is suppressed, there is a problem that the cost is high.

  Further, in the conventional correction member 110, the surface of the white hiding layer 105 that has been peeled off from the interface becomes a smooth surface, and therefore, the surface of the white hiding layer 105 is printed and printed with characters, figures, patterns, and the like using aqueous ink. As a result, the ink-absorbing property of the white hiding layer 105 is deteriorated. For this reason, there is a problem that blurring of printing and printing occurs and color change occurs (color reproducibility deteriorates).

  The present invention aims to solve this problem.

  That is, according to the present invention, when the correction member is transferred to the transfer paper, it is easy to agglomerate and peel the portion near the surface from the main body portion of the receiving layer of the correction member, thereby preventing the correction member from cracking. And when the transfer of the correction member is completed, the correction member can be easily cut, and after the correction member is transferred to the transfer paper, An object of the present invention is to provide, at a low cost, a correction member that suppresses the glossiness of the surface and prevents the occurrence of printing with a water-based ink, blurring of a print, and discoloration.

  Hereinafter, the present embodiment will be described with reference to the drawings. FIG. 1 is an enlarged cross-sectional view of a correction member showing an embodiment of the present invention. FIG. 2 is an explanatory view for explaining the usage of the correction member according to the embodiment of the present invention. FIG. 2A shows an image such as a figure or a pattern printed or printed on the surface of the transfer paper. Shown is a step (first step) in which the correction member is adhered to the surface of the transfer paper with the pressure-sensitive adhesive layer facing down, and (b) a state in which the vicinity of the surface of the receiving layer is held on the surface of the support And (c) a step of printing and printing an image of a corrected character, figure, pattern or the like on the exposed surface of the main body of the receiving layer. (Third stage) is shown.

  Conventionally, the “peeling” that is peeled off at the surface where the surface of one layer and the surface of the other layer are in contact is referred to as “interfacial peeling” as described above. Then, the layers themselves are not destroyed and peeled off, but are peeled off at the surface where the surface of one layer is in contact with the surface of the other layer. In the conventional “interface peeling”, for example, as shown in FIG. 4, a release agent treatment is performed on the support 102 to form a release layer 103, whereby the support 102 and the ink layer ( Since the bonding strength with the white hiding layer 105), that is, the coating strength can be further reduced, peeling between these layers is realized. On the other hand, “aggregated peeling” in the present invention is peeling that occurs when the receiving layer 4 itself is broken, as shown in FIG. 2, for example. Thus, in order for the receiving layer 4 itself to be destroyed at the time of peeling, the adhesive strength between the respective layers can be reduced by reducing the blending ratio of the film forming agent among the filler and the film forming agent constituting the receiving layer 4. Since the bonding force (coating strength) of the receiving layer 4 can be kept lower than that, it is possible to cause cohesive peeling. Such cohesive peeling is caused by the adhesive layer having the lowest strength among the adhesive force between the interfaces of the receptor layer 4, the white hiding layer 5 and the pressure-sensitive adhesive layer 6 constituting the ink layer, and the cohesive force between the layers. Happens at 4. In this specification, the cohesive peeling defined in this way is called “cohesive peeling”.

  As shown in FIGS. 1 and 2, the correction member 10 of the present invention includes a release layer 1, a support 2 provided on the surface of the release layer 1, and a surface of the support 2. And the white hiding layer 5 provided on the surface of the receiving layer 4 and the pressure-sensitive adhesive layer 6 provided on the surface of the white hiding layer 5.

And (c) calcium phosphate / calcium carbonate having a primary particle size of 0.04 to 25 μm and an average oil absorption of 100 to 170 ml / 100 g. Consists of a complex. The calcium phosphate / calcium carbonate composite (Polonex, manufactured by Maruo Calcium Co., Ltd.) is a specific surface area having a petal-like porous structure and extremely large oil-absorbing fine particles, and is already marketed as a matting agent for aqueous emulsion paints. It is what.

(B) the film-forming resin is composed of polyvinyl alcohol or a resin mixture composed of polyvinyl alcohol and maleic anhydride-modified chlorinated polypropylene, and (c) the filler is a primary particle. Since it is composed of a calcium phosphate / calcium carbonate composite having a diameter of 0.04 to 25 μm and an average oil absorption of 100 to 170 ml / 100 g, when the correction member 10 is transferred to the transfer paper 7, Of the receiving layer 4 It is easy to agglomerate and peel the surface vicinity portion 4b from the body portion 4a, prevent the correction member 10 from cracking, and the correction member 10 is easy to cut when the transfer of the correction member 10 is completed. Moreover, after the correction member 10 is transferred to the transfer paper 7, the glossiness of the surface of the main body portion 4a of the receiving layer 4 after the cohesive separation is suppressed, and printing and printing with water-based ink are suppressed. The correction member 10 that prevents the occurrence of bleeding and discoloration can be provided at a low cost.

  When the primary particle size is less than 0.04 μm, the aggregated peeling does not occur (interfacial peeling), and thus the water-based ink absorbability of the main body portion 4a of the receiving layer 4 decreases. In addition, when the average oil absorption is less than 100 ml / 100 g, cohesive separation does not occur (interfacial separation), and thus the water-based ink absorbability of the main body portion 4a of the receiving layer 4 decreases. And when the said primary particle diameter exceeds 25 micrometers, film strength will fall and the crack will generate | occur | produce in the main-body part 4a of the receiving layer 4 for that. On the other hand, when the average oil absorption exceeds 170 ml / 100 g, the coating strength is lowered, and therefore, the main body portion 4a of the receiving layer 4 is cracked. Therefore, in the present invention, the filler is composed of a calcium phosphate / calcium carbonate composite having a primary particle size of 0.04 to 25 μm and an average oil absorption of 100 to 170 ml / 100 g.

  In the present invention, the constitution of (c) is as follows: “The filler is a primary inorganic particle having a primary particle size of 0.04 to 6 μm and an average oil absorption of 35 to 55 ml / 100 g; It is also possible to have the following configuration (F): 15-25 μm, average oil absorption: 110-150 ml / 100 g of the second inorganic filler.

The absorbability of the water-based ink in the main body portion 4a is lowered. Further, when the primary particle diameter of the first inorganic filler exceeds 6 μm and the primary particle diameter of the second inorganic filler exceeds 25 μm, the coating strength is reduced. Cracks occur in 4a. And when the average oil absorption amount of the first inorganic filler is less than 35 ml / 100 g and the average oil absorption amount of the second inorganic filler is less than 110 ml / 100 g, the cohesive peeling does not occur and the interface peels.

It is possible to provide, at a low cost, the correction member 10 that suppresses the glossiness of the surface of the main body portion 4a of the receiving layer 4 after being applied, and prevents the occurrence of printing, blurring or discoloration of water-based ink. it can.

  In the constitutions (a) and (d), when the film-forming resin in the receiving layer 4 is less than 20% by weight, the film cannot be formed, and the peeling force is reduced, resulting in poor adhesion to the support layer, and When the film-forming resin in the receiving layer 4 exceeds 35% by weight, it becomes impossible to agglomerate and peel, and the peeling force becomes high, resulting in poor transfer. Further, if the filler in the receiving layer 4 is less than 65% by weight, it becomes impossible to agglomerate and peel, and the peeling force becomes high, resulting in poor transfer, and if the filler in the receiving layer 4 exceeds 80% by weight. The film cannot be formed, and the peeling force is reduced, resulting in poor adhesion to the support. Therefore, in the present invention, the receiving layer 4 is preferably composed of a film containing 20 to 35% by weight of a film-forming resin and 65 to 80% by weight of a filler. Thus, when the said receiving layer 4 is comprised with the film containing 20-35 weight% of film forming resin and 65-80 weight% of fillers, it is the surface vicinity from the main-body part 4a of the receiving layer 4 in the correction member 10. The portion 4b is easily agglomerated and peeled off.

  Further, in the configurations (a) and (d), when the thickness of the receiving layer 4 is less than 3 μm, the absorbability of the water-based ink is lowered. When the thickness of the receiving layer 4 exceeds 16 μm, when the correction member 10 is wound into the container, the correction container 10 cannot enter the standard container, and when the transfer of the correction member 10 is completed, It becomes difficult to cut. Therefore, in the present invention, the thickness of the receiving layer 4 is preferably 3 to 16 μm. Thus, when the thickness of the receiving layer 4 is 3 to 16 μm, when printing and printing with water-based ink on the surface of the correction member 10, that is, the surface of the main body portion 4 a of the receiving layer 4, The permeability of the water-based ink is further improved, the occurrence of bleeding due to the water-based ink is eliminated, and when the correction member 10 is rolled and placed in the container, it can be placed in a standard container, and the correction member 10 When the transfer is completed, the correction member 10 is easily cut.

  When the polyvinyl alcohol in the receiving layer 4 is less than 3% by weight, when the correction member 10 is printed with the water-based ink, that is, when the surface of the main body portion 4a of the correction member 10 is printed or printed, And when the polyvinyl alcohol in the said receiving layer 4 exceeds 13 weight%, the permeability of water-based ink will fall. Further, when the maleic anhydride-modified chlorinated polypropylene in the receiving layer 4 is less than 2% by weight, the concentration of the aqueous ink is lowered, and the maleic anhydride-modified chlorinated polypropylene in the receiving layer 4 is 7% by weight. On the other hand, the permeability of the water-based ink is lowered. Therefore, in the constitutions (a) and (d) of the present invention, the resin mixture is preferably 3 to 13% by weight of polyvinyl alcohol (a ratio of the entire receiving layer) and maleic anhydride-modified chlorinated polypropylene 2 to 2. It is composed of 7% by weight (the ratio of the entire receiving layer). Thus, when the resin mixture is composed of 3 to 13% by weight of polyvinyl alcohol (ratio to fill the entire receiving layer) and 2 to 7% by weight maleic anhydride-modified chlorinated polypropylene (ratio to fill the entire receiving layer), When the surface of the correction member 10, that is, the surface of the main body portion 4 a of the receiving layer 4 is printed and printed with aqueous ink, the permeability of the aqueous ink is improved, and bleeding due to the aqueous ink is eliminated.

  In the configuration (f), the filler is preferably composed of a first inorganic filler made of calcium carbonate and a second inorganic filler made of magnesium carbonate. Thus, when the filler is composed of the first inorganic filler made of calcium carbonate and the second inorganic filler made of magnesium carbonate, the surface of the correction member 10, that is, the receiving layer. When printing or printing on the surface of the main body 4a with water-based ink, the permeability of the water-based ink is improved, and bleeding due to the water-based ink is hardly generated.

   In the configuration of (f), the filler is preferably composed of calcium carbonate having a primary particle size of 0.04 to 6 μm and magnesium carbonate having a primary particle size of 15 to 25 μm, and the calcium carbonate The ratio of magnesium carbonate to the magnesium carbonate is preferably 1: 2 to 1:10. Thus, the filler is composed of calcium carbonate having a primary particle size of 0.04 to 6 μm and magnesium carbonate having a primary particle size of 15 to 25 μm, and the ratio of the calcium carbonate to the magnesium carbonate is 1 : When it is set to 2 to 1:10, it becomes easier to agglomerate and peel the surface vicinity portion 4b from the main body portion 4a of the receiving layer 4 in the correction member.

  In the constitutions (a) and (d), the receiving layer 4 is made of, for example, polyvinyl alcohol having a solid content of 30% (degree of saponification: 86.5-89.5 mol%, solid content: 18% , An aqueous solution) and maleic anhydride-modified chlorinated polypropylene (molecular weight: 5000 to 60000, solid content: 30%, aqueous emulsion).

  As shown in FIG. 2, the transfer paper 7 is placed with the pressure-sensitive adhesive layer 6 facing down so that the correction member 10 of the present invention covers an image such as a figure or a pattern printed on the surface of the transfer paper 7. At the stage where the support 2 is peeled from the receiving layer main body 4a in a state where the surface vicinity portion 4b of the receiving layer 4 is held on the surface of the support 2, the correcting member 10 of the present invention is It has been described in any one of Claims 1-6 which has the said adhesive layer 6, the said white hiding layer 5, and the said receiving layer 4 in order on the surface of the to-be-transferred paper 7, The receiving layer 4 is peeled from the surface vicinity portion 4b. As shown in FIG. 2, the receiving layer body 4a after the cohesive separation has fine irregularities on its surface. Thus, the correction member 10 of the present invention is such that the main body portion 4a of the receiving layer 4 after the cohesive separation has fine irregularities on the surface thereof. This suppresses the glossiness of the surface of the ink and prevents the occurrence of blurring or printing due to water-based ink, printing, or discoloration.

  The release layer 1 is used to prevent the pressure-sensitive adhesive layer 6 from sticking to the support 2 and not being peeled off when the correction member 10 is wound up in a roller shape. Although it is a release agent to be constructed, a release agent other than silicone may be used as long as it does not contradict the object of the present invention.

Through these steps, a correction member was obtained.

  As mentioned above, "peeling force (N / 10mm)" of the correction member obtained in Examples 1-5 and Comparative Examples 1-3, and the correction member obtained in Examples 6-10 and Comparative Examples 4-7, It was tested for “adhesive strength (N / 10 mm)”, “tensile strength (N / 10 mm)”, “transferability”, “surface gloss”, “ink absorbability” and “print reproducibility”. The “peeling force (N / 10 mm)” is measured according to JIS Z 0237.10.1, using the adherend as an ink layer, and the “adhesive strength (N / 10 mm)” is JIS Z 0237.10. 1. The adherend was measured as plain paper, and the “tensile strength (N / 10 mm)” was measured according to JIS Z 0237.10.1. The “transferability” and the “surface glossiness” were each measured visually using a transfer tool (WHIPER mini (5 mm), manufactured by Plus Stationery Co., Ltd.) with the transfer paper as plain paper. In addition, the “ink absorbability” and the “print reproducibility” can be transferred using a transfer tool (WHIPER mini (5 mm), manufactured by Plus Stationary) and a printer (PMG-850, manufactured by EPSON). The paper was used as plain paper and measured visually.

  The measurement results are shown in the following Table 1, Table 2, Table 3, and Table 4.

  The required quality of “peeling force” described in Tables 1 to 4 is 0.01 to 0.04 N / 10 mm, the required quality of “adhesive strength” is 0.02 to 0.05 N / 10 mm, and The required quality of “tensile strength” was 0.20 to 0.40 N / 10 mm. In addition, the required quality of “transferability” described in Tables 1 to 4 is that there is no occurrence of cracks at the time of transfer, and the cutting property of the correction member at the end of transfer is good, and “surface gloss” The required quality of the ink is that the corrected ink after transfer is visually compared with the transferred paper and the surface of the ink after transfer, and the required quality of "ink absorbency" is The surface of the correction member is printed with water-based ink, and the ink is immediately absorbed without bleeding, and the required quality of “print reproducibility” is printed with water-based ink on the surface of the correction member after transfer. The printed originals made with the water-based ink were compared visually to determine no bleeding or discoloration.

  The following can be seen from Tables 1 to 4. That is, in Comparative Examples 1 and 4, since the thickness of the receiving layer is less than the lower limit of the range specified in the claims, the peeling occurs and the ink absorbability is poor. In Comparative Examples 2 and 7, since the blending ratio of the filler exceeds the upper limit of the range specified in the claims, cracking of the ink occurs during transfer, and the transparency of the ink layer is reduced. As a result, whitening of the image has been invited. In Comparative Example 3, since the blending ratio of the filler is less than the lower limit of the range specified in the claims, the tape cutting ability is deteriorated, and the water-based ink lacks the absorbability. In Comparative Example 5, when large and small particles having different particle diameters are used as the filler, the blending ratio of the small diameter particles exceeds the upper limit of the range specified in the claims. The tape is cracked above the tensile strength of the ink layer, and the transparency of the ink layer is lowered, leading to whitening of the printed image. In Comparative Example 6, since the maleic anhydride-modified chlorinated polypropylene exceeds the upper limit of the range specified in the claims, the absorbability of the water-based ink deteriorates. Insufficient reproducibility. However, in Examples 1-10, such a problem does not arise. Comparative Example 8 is a conventional correction member that peels off at the interface. In this comparative example 8, the transferability is good, but the surface has a remarkable glossiness, the water-based ink absorbability is reduced and the print is blurred, and the color is very dull compared to the print original. Is scarce. However, in Examples 1-10, such a problem does not arise.
