Anti-counterfeit documents

Abstract

To provide a counterfeit prevention document that enables re-adhering an RFID label easily upon manufacturing, and enables preventing illegal replacement of the RFID label.SOLUTION: A document sheet 6 has a plurality of half-cut non-continuous notch lines 21 that is formed in an adhesion part 9 for adhering an RFID label 7, in which on a surface of the adhesion part 9, an initial ease-to-peel layer part 25 is provided that has varnish including a transparent pigment or silicon coated. The RFID label 7 is adhered in the adhesion part 9 by an adhesive layer of a rear surface. According to such a configuration, at an initial stage with the RFID label 7 adhered to the initial ease-to-peel layer part 25, the adhesive layer is adhered via the initial ease-to-peel layer part 25. Thus, while the RFID label 7 can be easily peeled, the adhesive layer is bonded to the document sheet 6 as a time goes by, so that the document sheet 6 is broken if the RFID label 7 is peeled.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to a form having an RFID label affixed to the form paper, and to a forgery prevention form that prevents the RFID label from being forged. [Background technology]

[0002] In recent years, documents affixed with RFID labels that enable contactless communication have become widely used in fields such as logistics, medicine, and factory production. RFID labels generally have an IC chip and antenna mounted on a substrate such as film, and are attached to the document with an adhesive applied to the back.

[0003] Forms with RFID labels affixed to them may be counterfeited if the RFID label is fraudulently replaced. To prevent this, Patent Document 1, for example, proposes a configuration for destroying the IC chip (RFID circuit) of an RFID label when the RFID label is removed from the form. With this configuration, the IC chip becomes unusable when the RFID label is removed from the form, preventing the fraudulent act of attaching the RFID label to another form. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-156922 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the form is produced by attaching an RFID label to a predetermined form paper. When attaching this RFID label, the attachment position may be shifted. However, with the configuration of Patent Document 1 mentioned above, if the RFID label is peeled off to reattach it when the attachment position is shifted, the IC chip is destroyed, and the label cannot be reattached and is discarded. Therefore, if the RFID label is misaligned when attached, production efficiency decreases.

[0006] The present invention proposes a forgery prevention document that allows RFID labels to be reattached during manufacturing and that can prevent the RFID labels from being rigged. [Means for solving the problem]

[0007] The present invention is an anti-counterfeit document comprising a form paper, an RFID label having an IC chip and an antenna, and attached to the surface of a predetermined attachment area of ​​the form paper by an adhesive layer provided on the back side, wherein the form paper has a plurality of discontinuous cut lines formed at intervals from each other in the attachment area and cut in a half-cut shape, and an initial easy-to-peel layer portion formed on the surface of the attachment area and coated with a varnish containing a transparent pigment or silicon.

[0008] In this configuration, the varnish of the initial peelable layer is formed so as to rest on the surface of the form when initially applied, and gradually penetrates between the paper fibers of the form as time passes after application. As a result, when an RFID label is affixed to the form, the adhesive layer of the RFID label is attached to the form via the initial peelable layer. Therefore, the RFID label can be easily peeled from the form in the early stages after affixing it. However, as time passes after affixing the RFID label, the initial peelable layer penetrates between the paper fibers of the form, causing the adhesive layer of the RFID label to come into contact with the form, making it difficult to peel the RFID label from the form. Furthermore, because discontinuous cut lines are formed in the affixed portion of the form, the form tears relatively easily from the discontinuous cut lines when the RFID label is peeled off.

[0009] As described above, the configuration of the present invention allows RFID labels to be easily reattached if they are misaligned during manufacturing, thereby preventing a decline in production efficiency due to misalignment. When the RFID label is used as a product, time has passed since it was attached (manufactured), and if the RFID label is fraudulently removed, the form paper will be damaged and fragments will adhere to the RFID label, leaving clear evidence of fraud. Therefore, fraudulent behavior such as replacing the RFID label can be prevented.

[0010] In the above-mentioned anti-counterfeit document of the present invention, a configuration is proposed in which the document paper has a plurality of discontinuous cut lines formed in a roughly V-shape radially at the attachment portion.

[0011] In this configuration, the discontinuous cut lines, which are roughly V-shaped and arranged radially, make it easier for the RFID label to be destroyed by the discontinuous cut lines no matter which direction the label is peeled from. This makes it more likely that the form paper will be destroyed if the RFID label is fraudulently peeled off, thereby improving the effectiveness of preventing fraudulent acts.

[0012] In the above-described anti-counterfeit document of the present invention, the initial peelable layer of the document paper is provided except for non-coated peripheral areas that are defined so as to overlap with each of the discontinuous cut lines. Here, the non-coated peripheral areas are preferably configured to be the peripheral areas surrounding each of the discontinuous cut lines.

[0013] With this configuration, in the early stages after the RFID label is affixed to the form, the adhesive layer of the RFID label is prevented from coming into contact with the form in the non-coated area, making the RFID label relatively easy to peel off. Over time, however, the adhesive layer of the RFID label comes into direct contact with the form in the non-coated area, firmly adhering the RFID label to the form. This makes it easier for the form to be destroyed along the discontinuous cut lines if the RFID label is fraudulently peeled off, leaving traces of fraud. Therefore, this configuration further enhances the effectiveness of preventing fraudulent activity.

[0014] In the above-mentioned anti-counterfeit document of the present invention, the initial easy-peel layer portion of the document paper is proposed to be composed of high-area coated portions and low-area coated portions having relatively different proportions of the area to which varnish is applied, and the high-area coated portions and low-area coated portions are arranged alternately in one direction.

[0015] With this configuration, initially after the RFID label is attached to the form, the adhesive layer of the RFID label is attached to the form via the initial easy-peel layer portions (the high-area coating portion and the low-area coating portion), making the RFID label relatively easy to peel off. However, over time, the adhesive layer in the low-area coating portion is more likely to adhere directly to the form than in the high-area coating portion, allowing the adhesive layer to adhere more strongly to the form. This makes it relatively difficult to peel the RFID label in the low-area coating portion and relatively easy to peel the RFID label in the high-area coating portion. As a result, when the RFID label is peeled off, the peeling speed varies between the high-area coating portion and the low-area coating portion, which are alternately arranged in the longitudinal direction, making the form more easily destroyed in the low-area coating portion.

[0016] In the above-described anti-counterfeit document of the present invention, a configuration is proposed in which the document paper has a background pattern printed at least in the attachment area. Here, the background pattern may be printed on at least one of the front and back surfaces of the attachment area of ​​the document paper.

[0017] In this configuration, the discontinuous cut lines can be concealed by the background pattern, which prevents fraudulent attempts to peel off the RFID label in a manner that corresponds to the arrangement or shape of the discontinuous cut lines (for example, the direction of peeling or the amount of force applied). [Effects of the Invention]

[0018] As described above, in the anti-counterfeit document of the present invention, the RFID label can be easily peeled off from the document paper in the early stages after it is affixed, so if a misalignment occurs during production, the RFID label can be re-affixed, thereby preventing a decrease in production efficiency due to the misalignment. Furthermore, by the time the anti-counterfeit document is used, a relatively long time has passed since it was manufactured, and peeling off the RFID label would damage the document paper, so it is possible to prevent fraudulent acts such as fraudulently peeling off and replacing the RFID label.

[0020] First and second embodiments of the present invention will be described with reference to the accompanying drawings. In the following Examples 1 and 2, the longitudinal direction of the continuous form paper 1 is the direction in which the multiple anti-counterfeit forms 5, 51 (form paper 6) are continued, and the direction perpendicular to the longitudinal direction is the width direction of the continuous form paper 1 and the anti-counterfeit forms 5, 51 (form paper 6). Note that the present invention is not limited to use in only these defined directions. [Example]

[0021] As shown in Figure 1(A), the continuous form paper 1 is made up of multiple anti-counterfeit forms 5 connected in the longitudinal direction, and includes a long, strip-shaped paper base material 2 made of high-quality paper or the like. The paper base material 2 has multiple perforations 4 formed across it widthwise at predetermined intervals in the longitudinal direction, and the form paper 6 that makes up the anti-counterfeit forms 5 is formed between adjacent perforations 4. The paper base material 2 can be easily folded and cut at these perforations 4.

[0022] Then, RFID labels 7 are attached between adjacent perforations 4 (document paper 6) of the paper base material 2. By cutting the perforations 4 of the paper base material 2, the anti-counterfeit document 5 according to this embodiment is produced.

[0023] As shown in FIG. 4, the RFID label 7 includes an RFID inlet 11 and a protective sheet 12 that covers the RFID inlet 11. The RFID inlet 11 is a non-contact, battery-less type that can transmit and receive signals such as commands and data contactlessly to and from an input / output device (reader / writer device, not shown) using HF-band electromagnetic waves. The RFID inlet 11 has an IC chip 16 and an antenna 17 disposed on one side (rear surface) of a thin-film inlet substrate 15. The antenna 17 is a multiple-loop antenna formed by winding a conductive wire multiple times in a loop shape (see FIGS. 1 and 2), and is printed on one side of the inlet substrate 15 with a conductive paste. The IC chip 16 is capable of electromagnetically storing required information and is adhered to and electrically connected to the antenna 17. The inlet substrate 15 is made of a substantially rectangular PET film, and an adhesive layer 18 is formed by applying an adhesive to one side (back side) of the inlet substrate 15 for adhering to the paper substrate 2 (document paper 6). In this embodiment, applying the adhesive also includes printing the adhesive.

[0024] The protective sheet 12 is made of a synthetic resin film having a substantially rectangular shape, and has an adhesive (not shown) applied to its back surface with a substantially uniform thickness. The protective sheet 12 in this embodiment is formed to have substantially the same length and width dimensions as the RFID inlet 11, and is attached to the surface of the RFID inlet 11 via the adhesive applied to its back surface. The adhesive and layer thickness are determined so that the adhesive strength of the back surface of the protective sheet 12 is stronger than that of the adhesive layer 18.

[0025] Next, the main part of the present invention will be described. As shown in Figures 1 to 3, each form paper 6 of the paper base material 2 has a pre-defined attachment area 9 for attaching an RFID label 7. A plurality of discontinuous cut lines 21 are formed at intervals in the attachment area 9. The discontinuous cut lines 21 are formed by half-cutting from the front side of the form paper 6 in the paper thickness direction, and are formed in a roughly V-shape. In this embodiment, the plurality of discontinuous cut lines 21 are provided radially in the attachment area 9. That is, the attachment area 9 has a plurality of discontinuous cut lines 21 with apexes 22 facing in eight directions (longitudinal direction, width direction, and ±45° directions).

[0026] Here, the discontinuous cut lines 21 are formed so that their depth from the surface of the form 6 is 40% to 70% of the thickness of the form 6. If this depth is shallower than 40%, the form 6 tends to be less stable when the discontinuous cut lines 21 are used to break the form 6 when the RFID label 7 is peeled off, as described below. On the other hand, if the depth is deeper than 70%, the form 6 may be torn for reasons other than peeling off the RFID label 7. The depth of the discontinuous cut lines 21 is more preferably 60% to 70% of the thickness of the form 6, which makes the form 6 more easily breakable when the RFID label 7 is peeled off. Furthermore, it is preferable that the discontinuous cut lines 21 have an interior angle of their apex 22 that is approximately a right angle or an acute angle. Such an interior angle configuration makes the form 6 more easily breakable when the RFID label 7 is peeled off.

[0027] The form 6 has an initial peelable layer 25 formed by applying varnish to the surface of the attachment area 9. In this embodiment, the varnish forming the initial peelable layer 25 is composed of an acrylic or epoxy resin component containing a transparent pigment containing a medium, and the transparent pigment content is adjusted to 20% to 30%. The thickness of the initial peelable layer 25 is determined by the difference in glossiness between its surface and the surface of the form 6. In other words, since the initial peelable layer 25 in this embodiment is transparent, its layer thickness (varnish application thickness) is set by the glossiness difference with the surface of the form 6 (non-varnished portion). Specifically, the glossiness of the initial peelable layer 25 is set to be 1.0 to 2.0 higher than the glossiness of the form 6. By determining the glossiness difference in this manner, an initial peelable layer 25 of a predetermined thickness can be formed. Note that in this embodiment, applying varnish also includes printing the varnish.

[0028] By setting the initial peelable layer 25 to the aforementioned transparent pigment content and layer thickness (gloss difference), the RFID label 7 can be easily peeled off at the beginning of application, and the form 6 can be destroyed when the RFID label 7 is peeled off long after application. Specifically, when the initial peelable layer 25 is formed by applying the varnish to the application area 9 of the form 6, the initial peelable layer 25 is formed in a state where it is placed on the surface of the application area 9. When the RFID label 7 is applied to the application area 9 of the form 6 in this state, the adhesive layer 18 of the RFID label 7 is attached to the surface of the form 6 via the initial peelable layer 25. Therefore, the RFID label 7 can be easily peeled off in this state. Meanwhile, as time passes after application of the RFID label 7, the initial peelable layer 25 gradually penetrates between the paper fibers of the form 6. As a result, after a relatively long time has passed since the label was attached, the adhesive layer 18 of the RFID label 7 will be directly adhered to the surface of the form 6. Peeling off the RFID label 7 in this state will destroy the form 6. The phenomenon in which the initial peelable layer 25 penetrates between the paper fibers over time is due to the transparent pigment containing medium contained in the varnish.

[0029] Furthermore, the initial easily peelable layer portion 25 is provided in the attachment area 9 except for non-coated peripheral areas 26 that overlap with the respective discontinuous cut lines 21. Here, the non-coated peripheral areas 26 include areas directly above the discontinuous cut lines 21 and are formed with a predetermined width around the discontinuous cut lines 21. Specifically, the non-coated peripheral areas 26 are formed with a width of 0.5 mm to 2.5 mm on one side around the discontinuous cut lines 21. The discontinuous cut lines 21 are positioned at a distance (the aforementioned width) from the initial easily peelable layer portion 25 by the non-coated peripheral areas 26. The area of ​​the initial easily peelable layer portion 25 is reduced compared to the area of ​​the attachment area 9 by these non-coated peripheral areas 26. The width dimension of the non-coated peripheral areas 26 is set so that the area ratio of the initial easily peelable layer portion 25 to the area of ​​the attachment area 9 is 50% or more. Note that this area ratio is preferably 60% to 80%.

[0030] By providing such a non-coated peripheral area 26, as described above, immediately after the RFID label 7 is attached, the adhesive layer 18 of the RFID label 7 is supported by the initial easy-peel layer portion 25 at the periphery of the non-coated peripheral area 26, thereby preventing the adhesive layer 18 from coming into contact with the form paper 6 in the non-coated peripheral area 26. As a result, in the early stages of attachment of the RFID label 7, the adhesive layer 18 of the RFID label 7 does not substantially adhere to the form paper 6 in the non-coated peripheral area 26, allowing the RFID label 7 to be easily peeled off. On the other hand, as time passes after the attachment of the RFID label 7, the adhesive layer 18 directly adheres to the form paper 6 in the non-coated peripheral area 26, making it easier for the form paper 6 to break at the discontinuous cut lines 21 when the RFID label 7 is peeled off.

[0031] In this embodiment, a background pattern 29 is printed over the entire back surface of the paper base material 2. This makes it difficult to see the discontinuous cut lines 21 provided in the attachment area 9 even when the form paper 6 is viewed through from the back side.

[0032] In this way, discontinuous cut lines 21 and an initial easy-peel layer portion 25 are formed in the attachment area 9 of each form paper 6 on the paper base material 2 of the continuous form paper 1, and a background pattern 29 is printed on the back surface. After the RFID label 7 is attached to the attachment area 9, the paper base material 2 is cut along the perforations 4 to obtain the anti-counterfeit form 5 of Example 1.

[0033] In the configuration of this embodiment, when the RFID label 7 is attached to each attachment portion 9 of the paper base material 2, if the RFID label 7 does not fit into the attachment portion 9 and becomes misaligned, the RFID label 7 can be peeled off and reattached. This is because, as described above, in the initial stage of attachment of the RFID label 7, the adhesive layer 18 of the RFID label 7 is attached to the paper base material 2 via the initial easy-peel layer portion 25, making the RFID label 7 easy to peel off. Here, in this embodiment, the initial stage of attachment in which the RFID label 7 can be easily peeled off refers to the period up to one hour after attachment of the RFID label 7, but depending on the storage environment, the RFID label 7 may be easily peeled off even after several hours (2 to 4 hours) have passed. Note that "easily peelable" means that the RFID label can be easily peeled off by anyone by hand and that no paper appears to be attached when peeled off. Therefore, if a skilled person takes the time to carefully peel it off, it may be possible to peel it off even several days (1 to 7 days) after application, but this does not fall under the category of "easy to peel off" in this example. Furthermore, peeling it off using a tool does not fall under the category of "easy to peel off" in this example.

[0034] Because the RFID label 7 can be reattached in the initial stage, even if misalignment occurs during the process of attaching the RFID label 7 to each attachment portion 9 of the paper base material 2, the RFID label 7 can be easily and stably reattached. Specifically, if misalignment occurs in the form paper 6 near the center of the paper base material 2 when attaching the RFID label 7 to each attachment portion 9 of the paper base material 2, the configuration of this embodiment allows for reattachment. If the attachment portion 9 of the paper base material 2 does not have the initial easy-peel layer 25, when misalignment occurs in the form paper 6 near the center of the paper base material 2, the misaligned form paper 6 must be cut at the perforations 4 before and after it, removed, and discarded. The configuration of this embodiment solves this problem.

[0035] Furthermore, by the time the anti-counterfeit form 5 cut from the continuous form paper 1 is used as a product, it will generally be about one week to one month after the production of the continuous form paper 1. Therefore, with the anti-counterfeit form 5 of this embodiment 1, if the RFID label 7 is fraudulently peeled off, the form paper 6 will be destroyed. This is because, as described above, as time passes after the RFID label 7 is affixed to the attachment area 9, the adhesive layer 18 of the RFID label 7 adheres directly to the form paper 6, and when the RFID label 7 is peeled off, it is easily destroyed from the discontinuous cut lines 21 at the attachment area 9. In particular, with the configuration of this embodiment 1, the non-coated peripheral area 26 is formed around the discontinuous cut lines 21, and the adhesive layer 18 is directly adhered to the form paper 6 in the non-coated peripheral area 26, making it even easier for the form paper 6 to be destroyed at the discontinuous cut lines 21 when the RFID label 7 is peeled off. Additionally, in this embodiment, since the multiple discontinuous cut lines 21 are radially arranged, the RFID label 7 is easily destroyed by the discontinuous cut lines 21 regardless of the direction from which it is peeled off. When the RFID label 7 is peeled off, a trace of the destroyed form 6 is left behind, which makes it possible to prevent such fraudulent acts. Furthermore, after peeling off the RFID label 7, pieces of the form 6 are stuck to it, making it impossible to affix it to anything else. This makes it possible to prevent fraudulent exchange of the RFID label 7.

[0036] Furthermore, since the background pattern 29 is printed on the back of the form paper 6 of the anti-counterfeit document 5, the shape and position of the discontinuous cut lines 21 are difficult to see even when viewed through light, etc. This prevents the RFID label 7 from being peeled off in a manner that corresponds to the arrangement and shape of the discontinuous cut lines 21 (for example, the direction of peeling or the amount of force applied), which contributes to the effect of preventing fraudulent acts of peeling off the RFID label 7. [Example]

[0037] 5 and 6, an initial peelable layer portion 55 coated with the same varnish as in Example 1 is formed on the surface of the attachment portion 9 of the slip paper 6. In Example 2, high-area coated portions 56 and low-area coated portions 57, which have relatively different proportions of the area coated with the varnish (hereinafter referred to as coated area ratios), are formed alternately in the longitudinal direction.

[0038] Here, the high-range application portions 56 are formed between the discontinuous incision lines 21 in the longitudinal direction so as not to overlap the discontinuous incision lines 21. The low-range application portions 57 are formed so as to overlap each of the discontinuous incision lines 21. In Example 2, the number of discontinuous incision lines 21 formed in the application area 9 is reduced compared to Example 1, ensuring a certain degree of longitudinal width for the high-range application portions 56. The discontinuous incision lines 21 are formed in the same shape (approximately V-shaped and deep) as in Example 1, and are arranged radially (in eight directions).

[0039] The high-area coated portion 56 is coated with a solid coat of varnish over its entire area, while the low-area coated portion 57 is coated with varnish in a dot pattern. Therefore, the low-area coated portion 57 has a lower varnish coating area ratio than the high-area coated portion 56. Specifically, the high-area coated portion 56 has a varnish coating area ratio of 100%, while the low-area coated portion 57 has a varnish coating area ratio of 40%. It is preferable that the low-area coated portion 57 has a varnish coating area ratio of 20% to 50%, and the difference between the low-area coated portion 57 and the high-area coated portion 56 is 50% to 80%. Note that in Example 2, the non-coated peripheral region 26 around the discontinuous cut lines 21 in Example 1 is not formed.

[0040] Example 2 is the same as Example 1 described above, except that an initial easy-peel layer portion 55 is provided at the attachment portion 9 of the form paper 6 (paper base material 2 of the form continuous paper 1), with high-frequency application portions 56 and low-frequency application portions 57 formed alternately.Therefore, the same components are given the same symbols, and their explanations are omitted as appropriate.

[0041] In the configuration of Example 2, similarly to Example 1, discontinuous cut lines 21 and an initial easy-peel layer portion 55 (high-frequency coating portion 56 and low-frequency coating portion 57) are formed in the attachment portion 9 of the paper base material 2, and a background pattern 29 is printed on the back surface. Then, after the RFID label 7 is attached to the attachment portion 9, the paper base material 2 is cut along the perforations 4 to obtain the anti-counterfeit document 51 of Example 2.

[0042] In this embodiment, as in the first embodiment, in the initial stage of attachment of the RFID label 7, the adhesive layer 18 of the RFID label 7 is attached to the paper base material 2 via the initial easy-peel layer portion 55, so that the RFID label 7 can be easily reattached. In this way, the configuration of the second embodiment also achieves the same advantageous effect as the first embodiment, that is, the RFID label 7 can be easily reattached in the initial stage of attachment.

[0043] Furthermore, when the counterfeit prevention document 51 of Example 2 is used as a product, more than one week has passed since its manufacture, and the varnish in the initial peelable layer 55 penetrates between the paper fibers of the document 6, causing the adhesive layer 18 of the RFID label 7 to directly adhere to the surface of the paper base 2. Here, the low-range coating portion 57 of the initial peelable layer 55 has a lower coating area ratio than the high-range coating portion 56. Therefore, the adhesive layer 18 is directly adhered to the document 6 in the non-varnished areas, and the varnish easily penetrates between the paper fibers of the document 6, causing the adhesive layer 18 to directly adhere to the document 6. As a result, the adhesive layer 18 of the RFID label 7 is more strongly adhered to the surface of the document 6 in the low-range coating portion 57 than in the high-range coating portion 56. Therefore, the RFID label 7 is relatively difficult to peel from the low-range coating portion 57, but is relatively easy to peel from the high-range coating portion 56. For this reason, when the RFID label 7 is peeled off, the high-area coating portions 56 and the low-area coating portions 57, which are alternately arranged in the longitudinal direction, produce varying degrees of tearing, making the form 6 more likely to be broken at the low-area coating portions 57. In particular, in Example 2, the discontinuous cut lines 21 are formed in the low-area coating portions 57, making it easier for tearing to occur from the discontinuous cut lines 21.

[0044] In this way, when the RFID label 7 is fraudulently removed from the anti-counterfeit document 51 of Example 2, a trace of destruction of the document paper 6 is left behind, and therefore, similar to Example 1, it is possible to prevent the act of fraudulently removing the RFID label 7. Also, in Example 2, the background pattern 29 is provided on the back surface of the document paper 6, which contributes to the effect of preventing the fraudulent act of removing the RFID label 7, similar to Example 1.

[0045] The present invention is not limited to the above-described first and second embodiments, and can be modified as appropriate within the scope of the present invention. For example, in the first and second embodiments, the RFID label 7 is attached to the continuous paper base material 2 of the form paper 6, but this is not limiting, and the RFID label 7 may be attached to the form paper 6 after it has been cut along the perforations 4 of the paper base material 2. Even with this configuration, the RFID label 7 can be reattached as in the first and second embodiments, and unauthorized removal of the RFID label 7 can be prevented.

[0046] In Examples 1 and 2, discontinuous cut lines 21 are radially arranged in a generally V-shape, but the shape, number, and arrangement of the discontinuous cut lines can be changed as appropriate. For example, discontinuous cut lines in a generally arc-shape or a generally W-shape can also be provided.

[0047] In Examples 1 and 2, the initial peelable layer is formed by applying a varnish containing a transparent pigment including a medium. Alternatively, the initial peelable layer can be formed by applying a varnish containing silicon. The silicon-containing varnish is an acrylic or epoxy resin containing 1% to 5% silicon, but does not contain a transparent pigment. When the initial peelable layer is formed using such a varnish in the same manner as in Examples 1 and 2, the same effects as in Examples 1 and 2 can be achieved.

[0048] In Examples 1 and 2, the initial easy peel layer portion 25, 55 is provided only in the attachment area 9 of the form paper 6, but this is not limited to this, and the initial easy peel layer portion 25, 55 may also be provided outside the attachment area 9.

[0049] In the first and second embodiments, the tint block 29 is printed on the back side of the form 6, but this is not limiting, and the tint block 29 may not be printed. [Explanation of symbols]
