Description

  The present invention relates to a pressure-sensitive adhesive tape with a metal-deposited foil obtained by transferring a metal-deposited foil to a pressure-sensitive adhesive tape and a method for producing the same.

  Conventionally, pressure-sensitive adhesive tapes based on paper such as crepe paper, kraft paper, or Japanese paper have been used as masking tapes for industrial applications, particularly for masking during painting (see, for example, Patent Document 1). The paper base masking tape has good hand cutting properties and can be easily cut by hand and attached to an object, and can be easily peeled off after being attached. However, even if the coating process progresses and masking is no longer necessary, there is a risk of forgetting to remove the masking tape. For this reason, the masking tape may be colored in a relatively conspicuous color so as not to forget to remove it.

  In recent years, masking tapes colored in prominent colors have attracted attention as new interior materials and decoration materials for home use and art. That is, the masking tape has become one of the media in which the user claims his / her hobbies and personality, and has been used in various fields such as various color-coded seals. As a masking tape, a variety of colorful patterns printed using a plurality of colors has been developed on the premise that the masking tape is not used for painting but for decoration. Today, masking tapes decorated with a wide variety of patterns are manufactured as products suitable for sale through stores and the Internet as household goods.

  In addition, adhesive tape with a metal foil layer is used for fixing heat insulating materials such as glass wool that keeps the piping warm and sealing gaps between units in the system kitchen because rigidity is required. (For example, refer to Patent Document 2). This adhesive tape forms a laminate with a molten film adhesive sandwiched between a base material such as a thermoplastic resin film, woven fabric, or paper and a metal foil such as aluminum, and is formed on one side of the laminate. Manufactured by applying an adhesive.

  Even when a colorful pattern is printed on the masking tape of the paper base, the printing ink soaks into the paper base, so that the outline of the pattern blurs and becomes unclear and the color becomes dull. At the boundary of different colors, they are mixed and blurred. The masking tape is provided as a product in a state wound in a roll shape. In the state of being wound and stored in a roll shape, there is an outer layer other than the outermost layer, and the pressure-sensitive adhesive on the back surface side of the outer layer is in contact with the surface other than the outermost layer. Even if the printing ink does not soak into the paper base and remains in the form of a film on the surface, when the masking tape is unwound, the ink film attached to the adhesive on the back side of the unwound part will be peeled off There is a fear.

  If metal is attached to the surface of the masking tape, it is expected that a glossy pattern impossible with printing inks colored with pigments or dyes can be formed. However, sufficient effects cannot be obtained by using printing ink mixed with metal powder. A metallic luster is obtained when it is deposited as a planar foil. As a method for producing a metal foil, there are a rolling method and a vapor deposition method.

  Since the metal foil used for the adhesive tape of patent document 2 is 5-70 micrometers in thickness and is described about workability, it is estimated that it manufactured by the rolling method. The rolled metal foil is relatively thick and has a weak surface and is easily wrinkled. Moreover, while having a sharp edge and having a possibility of cutting a hand during handling, as a masking tape, hand cutting property worsens and usability falls. In particular, the metal foil is not uniformly left on the surface of the paper base, but is partially adhered with an adhesive that has been adhered in accordance with the pattern shape, leaving the adhered portion, and removing the unbonded portion. When peeling and removing, it is difficult to leave a metal foil that matches the shape of the pattern, and even if the metal foil can be left to match the shape of the pattern, the outline of the pattern shape is clearly cut and left. It is difficult.

  In order to perform the vapor deposition for forming the metal foil by the vapor deposition method directly on the surface of the paper base material, it is necessary to coat the vapor deposition base layer in order to smooth the surface of the paper base material. This is because the surface of the paper substrate has large irregularities compared to metal vapor particles. However, the paper base is easily curled by coating and vapor deposition.

  A metal vapor-deposited foil that is hard to curl and has a strong surface is formed by vapor deposition on the surface of a flat vapor deposition substrate different from the paper substrate, and is transferred to the surface of the paper substrate. If the adhesive layer is formed in a pattern that matches the shape of the pattern, the paper substrate and the metal vapor-deposited foil are adhered, and the metal vapor-deposited foil excluding the bonded portion is removed. Can leave. Since the metal-deposited foil produced by the vapor deposition method is thinner than the metal rolled foil produced by the rolling method, the contour of the pattern shape is cut cleanly.

  Furthermore, no matter which metal foil is attached to the surface of the paper base material via the adhesive layer, the plasticizer is transferred from the pressure-sensitive adhesive layer formed on the back surface of the paper base material to the adhesive layer via the paper base material. There is a problem that it penetrates and reduces the adhesive strength of the adhesive layer. If the adhesive strength of the adhesive layer decreases in the state of being wound in a tape shape, when the upper layer portion is rewound and pulled out, the metal foil attached to the surface of the lower layer portion will be peeled off by the adhesive layer. There is a fear.

  The object of the present invention is to draw out by rewinding from the tape-shaped state without reducing the adhesive strength with the pressure-sensitive adhesive layer on the back side even if the metal vapor-deposited foil is bonded to the front side of the paper substrate. Even if it is made, it is providing the adhesive tape with metal vapor deposition foil, and its manufacturing method with which metal vapor deposition foil is hard to peel from the surface.

On the metal vapor-deposited foil after removing the vapor-deposited substrate from the metal vapor-deposited foil layer, it has a pattern printed with printing ink,
It is characterized by that.

Furthermore, the present invention is a method for producing a pressure-sensitive adhesive tape with a metal vapor-deposited foil, wherein the metal vapor-deposited foil is transferred and adhered to the front side of the paper substrate having a pressure-sensitive adhesive layer on the back side,
Before forming the adhesive layer on the back side of the paper substrate,
Applying an anti-soaking treatment to stop the impregnation of the adhesive and adhesive to the paper substrate,
A metal vapor-deposited foil layer comprising a metal vapor-deposited foil obtained by vapor-depositing a metal on a vapor-deposited base material and a top coat layer obtained by applying a topcoat agent onto the metal vapor-deposited foil and then drying is formed,

Further, in the present invention, the adhesive is applied on the top coat layer of the metal vapor-deposited foil layer by a gravure printing so that the metal vapor-deposited foil layer should partially remain,
On the gravure printing plate, the outline of the mesh part corresponding to the pattern shape is formed by rough engraving.
It is characterized by that.

Further, in the present invention, the anti-soaking treatment is performed by a process of compressing the paper base material between rolls.
It is characterized by

  According to the present invention, the pressure-sensitive adhesive tape with metal vapor-deposited foil transferred and adhered to the front surface side of the paper base material having the pressure-sensitive adhesive layer on the back side is applied to the paper base material and the paper base material. An anti-soaking treatment is applied to stop the impregnation of the adhesive and the adhesive. The adhesive layer formed on the paper base material is hardened on the front side by impregnation into the paper base material, and the penetration of the plasticizer from the adhesive layer on the back side is also stopped, so the adhesive strength does not decrease. . An overcoat layer is formed on the metal vapor deposition foil to protect the metal vapor deposition foil. The metal-deposited foil layer is protected by the overcoat layer, and the strength of the adhesive layer does not decrease. Therefore, even if the metal-deposited foil layer continues to be adhered and pulled out by rewinding from the state wound in the tape shape, It can be made difficult to peel off from the surface.

Moreover, according to this invention, an adhesive bond layer has a partial shape corresponding to the handle | pattern shape which should leave the said metal vapor deposition foil layer partially. Since the metal vapor-deposited foil layer is transferred after being formed by vapor deposition, when it remains as a partial transfer foil on the paper substrate through the partial shape of the adhesive layer, it will peel off sharply with the contour of the pattern shape Can do.
It is characterized by that.

  Further, according to the present invention, the adhesive layer is a uniform layer that joins between the top coat layer of the metal vapor-deposited foil layer and the paper substrate subjected to the anti-soaking treatment. The material can be securely bonded. Since the pattern is printed with printing ink on the metal vapor-deposited foil after removing the vapor deposition substrate from the metal vapor-deposited foil layer, the printing ink does not bleed and clear printing can be performed. For example, it is possible to print using a cover plate, or to print a pattern from one color to multiple colors using one plate to several plates, several types of plates, typesetting, or the like. Since the entire metal vapor-deposited foil is adhered on the paper substrate, it has a barrier property, and the work of closing the opened food or the like can be performed with good hand cutting properties.

  Furthermore, according to the present invention, the pressure-sensitive adhesive tape with metal vapor-deposited foil transferred and adhered to the surface side of the paper base material having the pressure-sensitive adhesive layer on the back side is subjected to an anti-soaking treatment to the paper base material. And the impregnation of the pressure sensitive adhesive and adhesive into the paper substrate is stopped. On the vapor deposition substrate, a metal vapor deposition foil layer including a metal vapor deposition foil by metal vapor deposition and a top coat layer by application and drying on the metal vapor deposition foil is formed. An adhesive is applied on the top coat layer of the metal vapor-deposited foil layer to form an adhesive layer. A metal vapor-deposited foil layer is deposited on the paper substrate through the adhesive layer, and after the adhesive layer is cured, the vapor deposition material is removed, and the metal vapor-deposited foil layer is protected with an overcoat layer. Manufactures self-adhesive tape. Since the impregnation is stopped by the anti-soaking treatment, even if the metal vapor-deposited foil is adhered to the front side of the paper substrate, the adhesive strength does not decrease with the adhesive layer on the back side, and the state is wound in a tape shape. Even when drawn out by rewinding, the metal-deposited foil protected by the overcoat layer can be made difficult to peel off from the surface.

  Further, according to the present invention, when applying the pattern on the top coat layer of the metal vapor-deposited foil layer with the gravure printing to leave the metal vapor-deposited foil layer partially on the gravure printing plate, The outline of the mesh portion corresponding to the pattern shape is formed with grooves. Grooves are formed in the contour part of the handle shape, making it difficult for the adhesive to flow out from the edge of the mesh to the surroundings, and forming a sufficient adhesive layer in the contour part to ensure partial transfer of the metal-deposited foil layer The bonding strength can be increased even in a fine pattern or a thin line portion where the bonding area is small.

  Further, according to the present invention, the water-proofing treatment is performed by compressing the paper base material sandwiched between rolls. The paper base material is clogged with paper fiber and becomes difficult to be impregnated with an adhesive or an adhesive. When a flat roll is used, the surface of the paper substrate in contact with the surface becomes flat, and when a metal-deposited foil is attached, gloss can be easily obtained.

FIG. 2 is a diagram showing a simplified configuration of a transfer foil bonding apparatus 10 for bonding the metal vapor-deposited foil layer 6 to the paper substrate 2 with the pressure-sensitive adhesive tape 1 with metal vapor-deposited foil of FIG.

FIG. 6 is a diagram showing an example of a pattern 34 printed on the metal-deposited foil layer 6 for full transfer as Example 2 of the present invention.

  Hereinafter, the adhesive tape 1 with metal vapor deposition foil by the partial transfer foil as Example 1 of this invention and its manufacturing method are demonstrated with FIGS. In FIG. 6, the example of the pattern printed on a whole surface transfer foil is shown as Example 2 of this invention. For convenience of explanation, portions that are not described in the drawings to be described may be referred to with reference numerals described in other drawings.

  FIG. 1: shows the schematic structure of the adhesive tape 1 with metal vapor deposition foil as Example 1 of this invention with the perspective view of (a), and sectional drawing of (b), respectively. The adhesive tape 1 with metal vapor deposition foil has the adhesive layer 3 in the back surface side of the paper base material 2, as shown to (b). The pressure-sensitive adhesive layer 3 is formed of a material as described in Patent Document 1, such as natural rubber or acrylic. However, the pressure-sensitive adhesive layer 3 is attached after the pattern shape 4 as shown by black coating with a metal-deposited foil is formed on the surface side of the paper substrate 2 and further after the overcoat layer 9 is formed. . (A) shows the state which has partly unwound from the adhesive tape 1 with a metal vapor deposition foil which adhered the adhesive layer 3 and wound up on the winding core 1a.

  The paper base 2 is subjected to a treatment for forming the coating layer 2a or a treatment for compression by sandwiching between rolls as an anti-soaking treatment for preventing impregnation of the adhesive or adhesive. Material 2A is used. The coating layer 2a is formed by applying a resin such as urethane or nitrified cotton in a state dissolved in a solvent. In the process of compressing between rolls, the paper substrate 2 is preferably sandwiched between an embossing roll having irregularities on the outer peripheral surface and a flat roll having a flat outer peripheral surface such as an iron mirror surface roll or rubber roll. When an embossing roll is used, fine irregularities are formed on the back side of the paper substrate 2 that is in contact with the embossing roll, and the embossing roll is partially pressed by the protruding portion of the embossing roll. It becomes difficult to impregnate. When a flat roll is used, the surface of the paper substrate that is in contact with the flat roll becomes smooth, and when a metal vapor-deposited foil is attached, the occurrence of burrs can be eliminated and gloss can be easily obtained. The anti-soaking treatment by compression with a roll is preferably performed immediately before bonding the pattern shape 4 with the adhesive layer 5.

  The pattern shape 4 shown to (a) is adhere | attached on the surface side of 2 A of immersion-proof paper bases with the adhesive bond layer 5, as shown to (b). If the paper base material 2 is stretched too much after the transfer of the metal vapor-deposited foil layer 6, random cracks may occur in the metal vapor-deposited foil layer 6 and the design properties may be impaired. When the coating layer 2a is provided, a function of stopping the elongation of the paper substrate 2 is also expected. The adhesive layer 5 is a two-component type, for example, a polyester type or a urethane type that is not easily affected by the plasticizer included in the pressure-sensitive adhesive layer 3. The adhesive main agent and the curing agent are mixed immediately before use, applied to the surface of the metal-deposited foil layer 6 on the topcoat layer 7 side, and then dried to form the adhesive layer 5.

  The metal vapor-deposited foil layer 6 is formed by vapor-depositing aluminum (Al) and has a thickness of about several hundred angstroms to several thousand angstroms. A topcoat layer 7 is formed on the surface of the metal vapor deposition foil layer 6 on the side where the adhesive layer 5 is provided. When the coating layer 2a is provided, the top coat layer 7 is a resin that is difficult to adhere and has a good compatibility with the adhesive. For example, if the adhesive is polyester, the top coat layer 7 is made of a resin material of the same system such as polyester. Form.

  As will be described later with reference to FIG. 3, the metal vapor-deposited foil layer 6 and the topcoat layer 7 are formed on the surface of the vapor-deposited base material 20 by sequentially forming the release agent layer 21 and the colored layer 8. In a state where the 7 side is adhered to the paper base material 2, the vapor deposition base material 20 is the uppermost layer of the paper base material 2. After the metal vapor-deposited foil layer 6 and the top coat layer 7 are bonded onto the water-proof treated paper substrate 2A, the vapor-deposited substrate 20 is removed, and after removal, an overcoat layer 9 made of an acrylic resin is formed. Since the pattern shape 4 is bonded in a state of protruding on the water-proof treated paper base material 2A, when unrolling as shown in FIG. 1 (a), the pressure-sensitive adhesive layer 3 is on the shoulder of the lower pattern shape 4 It is easily caught and peeled off. The overcoat layer 9 protects the metal deposited foil layer 6 at the handle shape 4, particularly at the shoulder. In order to make it difficult for the handle 4 to be peeled off, the handle 4 may be sandwiched between rolls or may be pushed into the paper substrate 2A using a stamp or the like to reduce the height of the shoulder portion. In the indentation treatment of the metal vapor-deposited foil layer 6 to reduce the height of the shoulder portion between the rolls, an embossing roll having irregularities on the outer peripheral surface, and a flat roll whose outer peripheral surface is flat with a metallic mirror roll or rubber roll It is preferable to sandwich the When it is desired to weaken the gloss of the metal-deposited foil layer 6 or to emboss the gloss with an embossed pattern, when an embossed roll provided with irregularities is applied to the surface side, irregularities are formed on the metal-deposited foil layer 6 and the gloss is increased. It is possible to simultaneously perform weakening and a calm texture, applying a pattern such as a texture or a mesh to the gloss, and reducing the adhesion area with the pressure-sensitive adhesive layer 3 by forming irregularities on the surface. Furthermore, the height of the shoulder portion of the metal vapor-deposited foil layer 6 is reduced, the amount of catching on the pressure-sensitive adhesive layer 3 is reduced, the adhesion strength of the metal vapor-deposited foil layer 6 is increased, and the design is improved. Effects can be obtained.

  FIG. 2 shows a simplified configuration of a transfer foil bonding apparatus 10 that bonds the metal vapor-deposited foil layer 6 in order to transfer the metal vapor-deposited foil layer 6 to the paper substrate 2 in the process of manufacturing the pressure-sensitive adhesive tape 1 with metal vapor-deposited foil of FIG. The transfer foil bonding apparatus 10 includes a transfer foil sheet unwinding machine 11, a transfer machine 12, an adhesive dryer 13, a nip roll 14, a paper base material unwinding machine 15, a winder 16 and a paper drying machine 17. The transfer foil sheet unwinder 11 unwinds the transfer foil sheet 6A wound in a roll shape. As shown in FIG. 3, the transfer foil sheet 6A has a top coat layer 7 formed on the surface thereof. The unwound transfer foil sheet 6A is sandwiched between the pattern roll 2a and the rubber roll 12b of the transfer machine 12. A concave portion is formed on the surface of the pattern roll 12a by a mesh pattern having a shape corresponding to the pattern shape 4, so that the adhesive liquid 5A in which the main agent and the curing agent are mixed adheres to the surface of the transfer foil sheet 6A. Gravure printed. A doctor knife 12c is applied to the outer periphery of the pattern plate roll 12a, and the adhesive liquid 5A adhering to other than the recesses is removed. From the transfer machine 12, the adhesive-coated transfer foil sheet 6 </ b> B having the adhesive liquid 5 </ b> A printed on the surface of the topcoat layer 7 comes out and enters the adhesive dryer 13. In the adhesive dryer 13, the adhesive liquid 5A is dried by hot air, an electric heater, a far-infrared heater, or the like. From the adhesive drier 13, the solvent component is discharged from the adhesive liquid 5 A, and the transfer foil sheet 6 C with the adhesive layer that becomes the semi-dry adhesive layer 5 comes out and enters the nip roll 14.

  In the nip roll 14, the transfer foil sheet 6 C with an adhesive layer and the immersion-proof paper base 2 A unwound from the paper base unwinding machine 15 are laminated so that the metal-deposited foil layer 6 is on the surface of the paper base 2. Transcribed. In the case of the two-component adhesive, complete curing is hindered by moisture and the adhesion strength is lowered. In order to prevent this, the paper substrate dryer 17 performs drying immediately before transfer. The completely cured adhesive force and the partially cured adhesive force are more completely cured and vary with time. The nip roll 14 is a heat roll, and the adhesive layer 5 is cured by being heated. The complete curing of the adhesive layer 5 is performed by winding the transfer foil laminated paper base material 1A laminated by the nip roll 14 by the winder 16, for example, in an aging room at 40 ° C. or 50 ° C. for about 3 to 4 days or 2 days. Each is achieved by putting it in. When the resin is coated for the water-proofing treatment of the paper base material 2, the coating resin and the resin of the top coat layer 7 may react with each other when the nip roll is heated and pressurized, and fogging may occur. Be careful to avoid it.

  If an ultraviolet (UV) curing type is used as the adhesive, it can be completely cured in a short time by irradiation with ultraviolet rays. However, since the ultraviolet rays hardly pass through the thick metal-deposited foil layer 6, the ultraviolet rays cannot reach the adhesive layer 5. In order to sufficiently cure the adhesive layer 5 with ultraviolet rays, the thickness must be such that the ultraviolet rays can penetrate the metal-deposited film foil layer 6, and sufficient metallic luster cannot be obtained. For the metal vapor-deposited foil layer 6 having such a thickness that a sufficient metallic luster can be obtained, the adhesive layer 5 is not sufficiently cured by ultraviolet rays, and the amount of adhesive applied is reduced. 6 becomes easy to peel off.

  As the adhesive layer 5, for example, a method of using a heat-sealing type, applying a pattern on the paper substrate 2 side and drying it first, and performing thermocompression transfer with a high-temperature heat roll such as 120 ° C. is considered. It is done. However, the pattern shape 4 may be crushed by the pressure during transfer.

  FIG. 3 schematically shows a cross-sectional configuration of the transfer foil sheet 6A of FIG. The metal vapor-deposited foil layer 6 is formed by vapor deposition of metal after forming the release agent layer 21 on the surface of the vapor deposition substrate 20 and forming the colored layer 8 on the colored material. By forming the colored layer 8, even if the metal vapor-deposited foil layer 6 is formed of aluminum, it can be colored gold or the like. When silver gloss is required, the colored layer 8 may not be used, but it is preferable to provide a transparent protective layer for preventing corrosion. A top coat layer 7 is formed on the surface of the metal vapor-deposited foil layer 6. A synthetic resin film such as polyethylene terephthalate (PET) can be used for the vapor deposition substrate 20.

  The transfer foil laminated paper substrate 1 </ b> A in FIG. 2 is removed by peeling the vapor deposition substrate 20 at the part of the release agent layer 21 after the adhesive layer 5 is completely cured. The metal vapor-deposited foil layer 6 remains in a state where only the portion where the adhesive layer 5 is formed is adhered to the surface of the paper substrate 2, the pattern shape 4 is formed by partial transfer, and after the overcoat layer 9 is formed, If the pressure-sensitive adhesive layer 3 is formed on the back side of the paper base material 2, the pressure-sensitive adhesive tape 1 with metal-deposited foil in FIG. 1 is obtained.

  FIG. 4 shows an example of the pattern shape 4 of the pressure-sensitive adhesive tape 1 with metal-deposited foil in FIG. The black portion of the figure is partially transferred by the metal vapor deposited foil layer 6. (A) shows the example of the pattern shape 4 in which a pattern is also formed inside. In such a pattern shape 4, when a crack occurs, it becomes unclear. (B) shows the example of the pattern shape 4 which arranges many fine shapes.

  FIG. 5 shows the effect of adding the raw engraving 24a to the mesh pattern 24 formed on the pattern roll 12a of FIG. In the pattern shape 4 as shown in FIG. 4, the contour is required to be clear. A mesh pattern 24 corresponding to the pattern shape 4 is usually formed on the surface of the pattern roll 12a of FIG. The size of the mesh is about 120 or 165. However, in the first embodiment, the raw engraving 24 a is added to the outline of the mesh pattern 24. As a result, an adhesive layer 5B to which the adhesive sufficiently adheres to the contour as shown in (b) is obtained. With only the mesh pattern 24, the adhesive flows outside the contour, and only the adhesive layer 5C in which a sufficient amount does not adhere to the contour is obtained. In Example 1, an adhesive layer 5B that retains sufficient adhesive is formed on the contour portion of the pattern shape 4, and the partial transfer of the metal vapor-deposited foil layer 6 is reliably performed, so that a fine pattern with a small adhesion area can be obtained. The adhesion strength can be increased even in the thin line portion.

  FIG. 6 shows an example of a pattern shape 34 printed on the metal vapor-deposited foil layer 6 for full transfer as Example 2 of the present invention. The pattern shape 34 is formed by printing with the printing ink on the surface of the metal vapor-deposited foil layer 6 transferred to the entire surface of the paper substrate 2. The process for producing the transfer foil laminated paper base material 1A by laminating the transfer foil sheet 6A on the water-proof treated paper base material 2A is performed by the transfer foil bonding apparatus 10 in FIG. It can be performed in the same manner as the tape 1. However, when the transfer machine 12 is used, the pattern plate roll 12a may be changed to a mesh roll that uniformly applies the adhesive liquid 5A to the surface of the top coat layer 7 of the transfer foil sheet 6A. After the adhesive layer 5 is completely cured, the vapor deposition substrate 20 is peeled off, but the release agent layer 21 is delaminated and the metal vapor deposition foil layer 6 remains entirely on the surface side of the paper substrate 2.

  In order to make it difficult for the metal vapor-deposited foil layer 6 transferred to the entire surface to be peeled off, the paper base material 2 to which the metal vapor-deposited foil layer 6 is bonded may be sandwiched between rolls in the same manner as the pattern shape 4 of partial transfer. In the process of sandwiching between rolls, it is preferable to sandwich between an embossing roll having irregularities on the outer peripheral surface and a flat roll having a flat outer peripheral surface with a metal mirror roll or rubber roll. When it is desired to weaken the gloss of the metal-deposited foil layer 6 or to emboss the gloss with an embossed pattern, when an embossed roll provided with irregularities is applied to the surface side, irregularities are formed on the metal-deposited foil layer 6 and the gloss is increased. It is possible to simultaneously perform weakening and a calm texture, applying a pattern such as a texture or a mesh to the gloss, and reducing the adhesion area with the pressure-sensitive adhesive layer 3 by forming irregularities on the surface.

  The pattern shape 34 is printed on the colored layer 8 using a concealed plate that attaches printing ink to the white portion of the figure. The metal vapor-deposited foil layer 6 uses a light-shielding property rather than a gloss, and can be used as a masking tape by printing on the colored layer 8 using a single plate or several plates, a plurality of types of plates, a type plate, etc. The adhesive tape 1 with metal vapor deposition foil which has the vivid single color or multicolor pattern shape 34 which is not influenced by the base | substrate to stick can be obtained.

  The anti-soaking paper substrate 2A and the transfer foil sheet 6A are wider than the product width of the pressure-sensitive adhesive tape 1 with metal-deposited foil. For example, if a width of 3 times or more is used, three types of pressure-sensitive adhesive tapes with metal-deposited foil having different pattern shapes 34 as shown in FIGS. 6 (a), (b) and (c) It can be manufactured at the same time until it is separated by a slitter. Even when the pattern shape 4 as shown in FIG. 4A is difficult in partial transfer, it is relatively easy in full transfer. In the face-down version, white and black may be reversed with respect to FIG. It is possible to manufacture a plurality of types simultaneously with a wide width by partial transfer as in the first embodiment.

  In the entire surface transfer as in the second embodiment, the concealing property is enhanced by the metal vapor-deposited foil layer 6, so that the pattern shape 34 having a bright gloss can be obtained without being influenced by the base. For example, when using adhesive tape with metal-deposited foil as a masking tape for coatings for building materials, automobiles, etc., even if paint is sprayed from above, the metallic luster remains, making it easy to identify the masking tape to be peeled off after the paint is dried Become. Moreover, since the aluminum metal-deposited foil layer 6 has a gas barrier property, it is possible to perform a close operation after opening food, medical products, cosmetics and the like with good hand cutting properties.
