Description of the Invention: [Technical Field of the Invention] The present invention relates to an electrically peelable adhesive article and a method for peeling the same. More specifically, in the electrically peelable adhesive article of the present invention, only a voltage is applied to lower the adhesive force, and as a result, the product can be easily peeled off from the body. « [Prior Art] Re-peelable adhesive tapes are used in various applications (for example, surface protective film, masking tape for coating, re-peelable note paper, etc.). The adhesive tape is composed of a general substrate and an adhesive layer laminated on the substrate. The adhesive layer needs to be adhesive and re-peelable at the same time. In other words, the adhesive layer needs to be adhered to the extent that it is not peeled off from the body when being handled, stored, or processed. Further, the adhesive layer needs removability which is easy to remove when the effect is achieved. As a method of realizing the above-mentioned adhesive properties and re-peelability, a method described in, for example, JP-A-2003-504504 (Patent Document 1), WO2007/018239 (Patent Document 2), and the like is proposed. Japanese Laid-Open Patent Publication No. 2003-504504 proposes an epoxy-based adhesive containing an epoxy compound having releasability when a voltage is applied. The epoxy compound exemplified in the examples is a specific compound having a disulfide bond in the molecule. This publication describes the use of the epoxy-based adhesive to provide a peelable adhesive when applied. On the other hand, WO2007/018239 discloses an adhesive which can be peeled off when a voltage is applied by using an ionic liquid as an additive. In this publication, the ionic liquid is a molten salt which is liquid at room temperature, has no vapor pressure of 4 322164 201113350 and has high heat resistance, incombustibility, high chemical stability and the like. [Prior Art] [Patent Document 1] [Patent Document 1] Japanese Patent Publication No. 2003-504504 [Patent Document 2] WO2007/018239 SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) However, by this epoxy When the adhesive is bonded, it can be peeled off at 60 ° C and 50 V for 30 minutes, and there is a need for heating and long-time application of voltage at the time of peeling. Further, the epoxy compound and the ionic liquid, as described in the above publications, are compounds having a special structure and are therefore expensive, and it is difficult to provide an inexpensive adhesive tape by using these. Furthermore, in the above technique, both the bonding material (adhesive tape and the object to be attached) must be electrically conductive and the use is limited. Therefore, it is desirable to provide a material which is inexpensive to use, and which can be peeled off even if it is not heated in a short time regardless of the conductivity of the object, and exhibits an adhesiveness equivalent to or higher than that in the case of using an epoxy compound or an ionic liquid.

The patterned planar shape of the opening of the layer. Further, the present invention provides a method for peeling off an electric-adhesive adhesive article, wherein the electro-peelable adhesive article faces the body by the electro-peelable adhesive layer, after being placed on the object, by the foregoing A voltage is applied between the conductive branch and the conductive layer to peel the electro-adhesive product from the object. (Effects of the Invention) The present invention can be provided at a low cost - an electrically conductive product which can be peeled off even if it is not heated in a short period of time by applying electricity. This effect is achieved by simultaneously having a composition of an electro-peeling adhesive having a specific property and a conductive layer having a shape of a planarized layer which exposes the mouth of the electro-peelable adhesive. Khan's 'In addition' the test contains the financial salt, which can improve the stripping. ^ Furthermore, the electrolyte contains the organic compound of the formula (8) of the organic (fourth) type (4) (the R is the same or different methyl or ethyl in the formula 322164 6 201113350) Sex. Further, when the electrolytic solution contains an organic solvent having a dielectric constant of 30 or more, the peeling property can be further improved. Further, when the electrolytic solution contains an organic solvent selected from the group consisting of ethyl carbonate, ethyl propyl carbonate, 7-butyrolactone, and N-f-based-2-pyrrolidone having a dielectric constant of 3 Å or more, the peeling property can be further improved. Further, when the acrylic adhesive contains a (meth) propyl group having a carbon number of 1 to 8 and a copolymer containing a thiol-based acrylic monomer and a hydroxyl group-containing acrylic monomer, , can improve the peeling. Further, when the conductive layer has a surface resistance value of 1000 Ω/□, the peeling property can be improved. Further, since the peeling of the electro-peelable adhesive article of the present invention reduces the adhesion of the electro-peeling adhesive layer by applying a voltage between the conductive support and the conductive layer, even if it is not heated in a short time It can also be peeled off.

It is preferred that the range of the dielectric constant is 6 Å or more. (Use ratio of adhesive to electrolyte) The electrolyte in the range of 15 to 250 reset parts is used with respect to 1 part by weight of the adhesive (solid content). By using this range, it is possible to achieve both the protection of the applied voltage and the adhesion of the unapplied power. It is preferred to use the electrolyte in a proportion of 40 to 120 parts by weight. (Other components) The crosslinking agent may also act on an acrylic adhesive to carry out crosslinking.

The conductive layer usually contains mainly a metal component. Examples of the metal component include metals such as gold, silver, copper, and nickel, alloys of these metals, metal oxides such as indium, tin oxide, tin oxide, and zinc oxide. Further, in addition to the metal component, a conductive material such as carbon, a conductive metal oxide or a conductive polymer may be used.

The content of the metal component in the composite is preferably from 30 to 99% by weight, preferably from 40 to 95% by weight, from the viewpoint of ensuring ease of production and conductivity. The composite may, for example, be a mixture of a metal component and a resin component, or a composite of a surface of a woven resin component coated with a metal component. The former mixture can be formed by printing a paste containing a metal component and a resin component on a release paper to a predetermined shape. The latter composite can be formed by depositing or depositing a metal component on the surface of the resin component. Among them, the former is easily patterned, is not contained in the adhesive layer, and is easily present on the surface of the adhesive layer, and is therefore preferred. The resin component is not particularly limited, and both a thermosetting resin and a thermoplastic resin can be used. In this case, a thermosetting resin (for example, a polyester, a benzene, an epoxy compound, or an acrylic acid) is used as a component, and deterioration of the resin component due to components other than the resin (for example, an increase in the surface resistance of the conductive layer) can be suppressed. It is better from the viewpoint of improving the stability of the adhesive product.

For example, the width of the conductive region is preferably 〇5 to ι ,, and preferably from 1.1 to 0.5. (D) Others The end of the 'electric layer is preferably a terminal provided in advance for applying a voltage to the conductive layer.

The terminal may be formed of gold, silver, copper, a metal of the metal, or an alloy of the metal. (E) The shape of the electrically detachable adhesive article, the shape of the adhesive product is not specified, and it can be determined by the rise of the conductive support. For example, when the conductive support is in the form of a foil, the article becomes an adhesive tape. (F) Method for Producing Electro-Releasable Adhesive Article The method for producing an adhesive article may be, for example, (1) forming an adhesive layer by applying an adhesive composition on a conductive branch body, and additionally forming a substrate for forming a conductive layer ( a method of printing a conductive layer on a release liner to transfer the conductive layer onto the adhesive layer; (2) forming a conductive layer on the conductive layer to form a conductive layer, by forming an adhesive layer on the conductive layer, A method of placing a conductive branch body on an adhesive layer or the like. In addition, when the conductive layer is composed only of a metal component, when it is composed of a composite formed by coating a surface of a resin component woven with a metal component, etc., when a layer which cannot be formed by a coating method is formed, for example, in conductivity A method of forming an adhesive layer on a support body by a coating method and placing a conductive layer on the adhesive layer. (G) Use of an electrically peelable adhesive article The use of the adhesive article may be, for example, a subsequent use of a metal material (e.g., aluminum, precious metal) necessary for reuse and other members. This use can easily recover metal materials by applying a voltage, for example, in the reuse of home appliances. Further, for example, the sensor and the intended use of the object can be cited. This application can easily recover the sensor by applying a voltage, and the sensor can be reused 18 322164 Λ 201113350 is quite economical. Further, the following uses of the collar used in the tracking mark of an animal can be cited. For this purpose, when no tracking is necessary, the phase engagement portion is applied with a remote operation to release the phase coil. In the manufacturing step, the temporary joining of the parts may use an adhesive article. For example, when performing dicing of LSI wafers, temporary bonding for wafers can be performed. For this purpose, the state of temporary bonding can be easily removed by applying a voltage. It can be used for the subsequent use of the satellite when it is detached from its frame. In the past, detachment has used methods that are difficult to control as accurately as rocket launches. However, if the adhesive article of the present invention is used, it can be precisely controlled by applying a voltage, and physical damage to the artificial satellite can be alleviated. 00 peeling method The above adhesive article can be adhered to the object to be placed. The body is not particularly limited and may be electrically conductive or insulative. The adhesive article of the present invention can be used even if it is an insulating material because it has a conductive layer. The peeling of the adherend of the self-adhesive article can be carried out by applying a voltage between the conductive support and the conductive layer. Specifically, by connecting the conductive support and the conductive layer terminals, a voltage is applied between the terminals to be peeled off from the object. The voltage to be applied is not particularly limited as long as it can be peeled off, and is preferably 3 V or more. The upper limit of the voltage is not particularly limited from the viewpoint of peeling off, but it is preferably 200 V or less in consideration of the voltage application device and the influence on the object to be placed. The application time is preferably, for example, 5 minutes or less.

The area A, the thickness L, and the electric resistance Rb were substituted into the following formula to calculate the ion conductivity σ of the adhesive composition. (Formula) σ = L / (RbxA) (Preparation of Conductive Layer) Silver paste A (D〇tite FA-353N, thermosetting polyester resin containing 69 weight of silver, manufactured by Fujikura Kasei Co., Ltd.) Acrylic resin (byk-350, manufactured by BYK Japan Co., Ltd.) (surface-adjusting leveling agent heavy star, polysulfide (by γ ja japan company byk_〇6 (10)) (antifoaming agent) 1 part by weight was uniformly mixed. The conductive layer was obtained by gravure printing the obtained mixed solution on a pET film subjected to polyelectrodoxy stripping treatment using the pattern of the pattern (1) in Fig. 1 . In Fig. 1, a is the width of the opening. (dot width), b is the width (line width) of the conductive region. 322164 21 201113350 (Modified electrically peelable adhesive article) The above adhesive composition is applied to the release liner (5) coffee Hner), and the obtained coating film In (10). c Dry for 2 minutes to obtain a thickness of 4 〇 (10) after leaving the H adhesive layer, in the conductive substrate as a conductive substrate (thickness 100 = attached to the electrically peelable adhesive layer. After that, at 4 (rc is matured in 3 days. Next, the release liner is peeled off, and the electrically conductive adhesive layer (adhesive tape) is obtained by attaching the above-mentioned conductive layer. The known peelable adhesive product is evaluated as follows. The results are shown in Tables 1 and 2. In the table, "parts" means parts by weight. (Evaluation of electrically peelable adhesive products) (1) Determination of surface resistance The surface resistance of the conductive pattern material alone and the adhesive tape was measured. A stainless steel electrode crucible (width A: 25 cm) is placed on the measurement target w at a predetermined distance L (3 〇 cm), and a weight Y of lkg is placed on each electrode (Fig. 2). Thereafter, the tester Z is used. The resistance value between the electrodes was obtained. The surface resistance (Ω/□) was calculated by the formula: surface resistance (i}/|:]) = R(n)xA(cm)/L(cm). The force of the adhesive tape was cut into a width of 25 mm x a length of 250 mm to obtain a test piece. The sample piece was placed on a PET plate (the body: Engineer ING Test Service Co., Ltd., using a 2kg rubber roller to roll back and forth in the length direction of the stripper at a speed of 3 〇〇匪/min, and press the test piece to obtain an evaluation sample. After pressing for 30 minutes, according to JIS Z -0237 is the standard, using the autograph AGS-Η manufactured by Shimadzu Corporation, and measuring the force required to peel (180° peel) at a tensile speed of 300 with a degree of 22 322164 201113350 180° (adhesion: IN/25mm) After the sample sample prepared in the same manner as described above was pressed for 30 minutes, the electrode was mounted on the conductive support and the substrate of the evaluation sample as shown in Fig. 3, and a voltage of 100 V was applied for 3 minutes. In the same manner as described above, the force required for peeling at 180° is measured. Fig. 3 is a schematic cross-sectional view showing a method of applying voltage. In the figure, 1 is a conductive support, 2 is an electrically peelable adhesive layer, and 3 is a conductive layer, 4 (2) Evaluation of the electric peeling electrical peeling property was evaluated by the degree of reduction of the adhesive force after applying a voltage (100 V for 3 minutes). The adhesive force after the applied voltage was calculated with respect to the applied voltage. Proportion of adhesion (%) is the retention rate of adhesion. When the retention rate is 20% or less, it is evaluated as ◎ when it is easy to peel off by application of voltage, and it is marked as 可 when it is larger than 20% and is evaluated as peelable when it is 50% or less. When it is larger than 50%, it is evaluated as X which is difficult to peel off. (Examples 2 to 18 and Comparative Examples 1 to 4) Electrical peelability was obtained in the same manner as in Example 1 except that the conductive layer and the adhesive layer shown in Table 1 were used. The adhesive product was obtained, and the obtained electrically peelable adhesive product was evaluated in the same manner as in Example 1. The results are shown in Tables 1 and 2. However, in Comparative Example 3 in which the amount of the electrolytic solution added was large, film formation by itself was impossible. In the examples and comparative examples of Tables 1 and 2, silver paste B was used as Dotite XA-824 (resin component: thermosetting phenol resin, containing 45 wt% of silver, manufactured by Fujikura Kasei Co., Ltd.), and polyester.
