Description

  The present invention relates to a cylindrical label used by being attached to various adherends such as beverage containers.

Conventionally, a cylindrical label in which a film is formed in a cylindrical shape is used for various applications.
Cylindrical labels can be broadly classified into the following three types according to the properties of the film or the attachment method to the adherend such as a container.
The first cylindrical label is a cylindrical label formed into a cylindrical shape by overlaying and bonding the back surface of the first side end portion of the heat-shrinkable film to the surface of the second other side end portion. . This first cylindrical label is also called a cylindrical shrink, a shrink label, or a heat-shrinkable cylindrical label. Hereinafter, in this specification, this type of cylindrical label may be referred to as a “heat-shrinkable cylindrical label”.
The second cylindrical label is a cylindrical label formed into a cylindrical shape by overlaying and bonding the back surface of the first side end portion of the self-stretchable film to the surface of the second other side end portion. . This second cylindrical label is also called a stretch label or a self-expandable cylindrical label. Hereinafter, in this specification, this type of cylindrical label may be referred to as a “self-expandable cylindrical label”.
The third cylindrical label is obtained by partially bonding the back surface of the second side end of the film to the container, wrapping the film around the container, and forming the first side end of the film on the surface of the second side end. It is a cylindrical label formed into a cylindrical shape by bonding the back surface. This third cylindrical label is also called a wound cylindrical label or a wound label. Hereinafter, in this specification, this type of cylindrical label may be referred to as a “wrapped cylindrical label”.

The cylindrical label is used as a decoration medium for displaying characters such as product names and designs such as decorative patterns. Among them, a so-called metallic-like cylindrical label exhibiting a metallic luster has an advantage of giving a high-class feeling to a product on which the label is mounted, and further attracting consumers' attention.
For example, Patent Document 1 discloses a high-intensity metallic printing shrink label (metallic tone print) in which a transparent colored ink printing layer is provided on the front side of the base film and a metal particle ink printing layer is provided on the back side of the base film. A cylindrical label) is disclosed. Such metallic cylindrical labels have a brilliant appearance.
However, the conventional metallic-like cylindrical label is too brilliant and may give a flashy and uncomfortable impression to consumers who see it. For example, for relatively expensive products such as cosmetics, a cylindrical label that can give a high-class feeling to consumers is desired, and such a cylindrical label has a moderate metal color and is calm. An appearance having a texture is required.

The “longitudinal direction” refers to a direction substantially orthogonal to the lateral direction in the plane of the substrate.
It should be noted that the shape, size, thickness of each layer, the relative ratio thereof, and the like shown in each drawing are different from actual dimensions.

[One Embodiment]
FIG. 1 is a perspective view of a label-forming base material used to form the cylindrical label of the present invention as viewed from the back side, and FIGS. 2 to 5 are cross-sections cut at each part of the base material. FIG. FIG. 6 is a perspective view of the cylindrical label of the present invention, and FIG. 7 is a cross-sectional view of a sealed portion of the cylindrical label.
1 to 5, the label forming substrate 1 includes a film 2, a matte colored layer 3, and a metal-containing layer 4. By forming the substrate 1 in a cylindrical shape so that the back surface of the film 2 is on the inside, a cylindrical label 10 as shown in FIGS. 6 and 7 can be configured.
As described above, the cylindrical label 10 can be roughly classified into a heat-shrinkable cylindrical label, a self-expandable cylindrical label, and a wrapping cylindrical label according to the properties of the film 2 or a method for attaching the adherend to the adherend such as a container. .

  Each of these cylindrical labels is common in that the substrate 1 is formed in a cylindrical shape. The difference is that the heat-shrinkable cylindrical label is formed from a base material having heat-shrinkability (property that shrinks in a predetermined direction when heat is applied), and is formed into a cylindrical shape before being attached to the adherend. The self-stretching cylindrical label is formed from a base material having a self-stretching property (a property that expands when pulled and returns almost to its original shape when the tensile force is released) and is attached to the adherend. Is formed from a base material having heat shrinkability or self-stretchability, or a base material having neither heat-shrinkability nor self-stretchability. In addition, it is formed in a cylindrical shape when wound around the adherend and mounted.

(Base material for label formation)
The label forming substrate 1 can be used as a substrate for forming any one of the above-described cylindrical labels by appropriately selecting the properties thereof.
A cylindrical label 10 is formed by forming a cylindrical shape so that the back surface of the label-forming base material 1 is inside, and overlapping and adhering the second side end portion to the surface side of the first side end portion. Is obtained.

The label-forming substrate 1 has a film 2 having a substantially rectangular shape in plan view, a matte colored layer 3 and a metal-containing layer 4, and if necessary, a supplementary colored layer 5 and an overcoat layer 6. And at least one functional layer selected from the design printing layer 7 and the inner surface layer 8.
In the mechanical production process, the label-forming substrate 1 is usually manufactured as an elongated substrate continuous body in which a plurality of label-forming substrates are continuously connected. In use, each label-forming substrate 1 is obtained by cutting the continuous body into a predetermined length.

(the film)
As the film 2, a transparent film is used in order to visually recognize the layer provided on the back side from the outside of the cylindrical label. In addition, in this specification, a certain member is "transparent" means that it has translucency which can visually recognize the color or display of the layer provided in the back surface side of the member from the surface side of the member.
The film 2 may or may not have at least one of heat shrinkability and self-stretchability. What is necessary is just to select the film 2 of the base material 1 for label formation according to the classification of a heat-shrinkable cylindrical label, a self-expandable cylindrical label, or a winding cylindrical label.

  The material of the film 2 is not particularly limited. In the case of a film having heat shrinkability, for example, heat of polyester resin such as polyethylene terephthalate, olefin resin such as polypropylene and cyclic olefin, styrene resin such as styrene-butadiene copolymer, and vinyl chloride resin. The stretched film containing a plastic resin is mentioned. In the case of a film having self-stretchability, examples thereof include a film containing an olefin resin such as polyethylene and a thermoplastic resin such as ethylene vinyl acetate copolymer. The self-stretchable film may have heat shrinkability in addition to self-stretchability. In the case of a film having neither heat shrinkability nor self-stretchability, examples thereof include a biaxially stretched polyester film, a biaxially stretched styrene film, and a biaxially stretched olefin film.

The substantially rectangular film 2 has a first side end portion 21 along the vertical direction and a second side end portion 22 along the vertical direction that opposes the first side end portion 21 in the horizontal direction. . The first side end portion 21 is a belt-like region including a first side end edge 21 a extending linearly along the vertical direction and extending in the vertical direction from the upper edge to the lower edge of the film 2. The second side end portion 22 is a belt-like region including a second side end edge 22a extending linearly along the vertical direction and extending in the vertical direction from the upper edge to the lower edge of the film 2. The said 1st side edge part 21 and the 2nd side edge part 22 comprise the seal | sticker part 9 which overlaps and adhere | attaches, when forming a cylindrical label.
The lateral widths of the first side end portion 21 and the second side end portion 22 are not particularly limited, but are usually 3 mm to 20 mm, preferably 5 mm to 15 mm. The horizontal width is a length in the horizontal direction.

(Matte colored layer)
The matte colored layer 3 is a layer containing a matting agent and a colorant, and is a layer that exhibits an arbitrary color in a matte tone.
The matte colored layer 3 is provided on the surface side of the film 2. The matte colored layer 3 may be provided directly on the surface of the film 2 as illustrated. Alternatively, although not particularly illustrated, a transparent resin layer may be provided on the surface of the film and a matte colored layer may be provided on the surface of the transparent resin layer, or a metal-containing layer may be provided on the surface of the film. Further, a matte colored layer may be provided on the surface of the metal-containing layer. Preferably, the matte colored layer 3 is provided directly on the surface of the film 2.
The matte colored layer 3 may be provided on the entire surface side of the film 2, but preferably, the matte colored layer 3 is not provided on the entire surface side of the film 2, There is a region that does not have the matte colored layer 3. In the illustrated example, the surface of the film 2 corresponding to the surface of the second side end portion 22 of the film 2 and the region where the design printing layer 7 is provided does not have the matte colored layer 3.
Specifically, the matte colored layer 3 is provided in a region surrounded by the upper edge 23a, the lower edge 24a, the first side edge 21a, and the boundary line of the second side edge 22 of the film 2. Yes. In other words, the outer edge of the matte colored layer 3 coincides with the boundary lines of the upper edge 23a, the lower edge 24a, the first side edge 21a, and the second side edge 22 of the film 2. Accordingly, the upper edge, the lower edge, the first side edge 31a and the second side edge 32a of the matte colored layer 3 are respectively the upper edge 23a, the lower edge 24a, the first side edge 21a and the second side of the film 2. It coincides with the boundary line of the end 22. The second side edge 32 a of the matte colored layer 3 faces the second side end 22 in the immediate vicinity of the second side end 22 of the film 2. Even if the matte colored layer 3 is provided in a solid shape in the entire region surrounded by the outer edge (the upper edge, the lower edge, the first side edge 31a and the second side edge 32a) of the matte colored layer 3 However, in the case where the design print layer 7 is provided on the film 2, in order to make the display of the design print layer 7 clearly visible from the outside of the cylindrical label 10, the region corresponding to the design print layer 7 is The window area is not provided with a matte colored layer.
The upper and lower edges of the matte colored layer 3 coincide with the upper and lower edges 23a and 24a of the film 2, but the matte colored layer 3 has an upper edge that is the upper edge 23a of the film 2. The lower edge may be disposed slightly closer to the lower side than the lower edge 24 a of the film 2.

The matte colored layer 3 has light transmittance as a whole. The light transmittance refers to a property that allows the metal color of the metal-containing layer 4 provided on the back surface side to be visually recognized through the matte colored layer 3. For example, the matte colored layer 3 has a light transmittance of, for example, a total light transmittance (JIS K7105) of 50% or more, preferably 60% or more. The total light transmittance of the matte colored layer 3 is a value measured using the film 2 on which the matte colored layer 3 is laminated.
The thickness of the matte colored layer 3 can be appropriately set within the range having the light transmittance, and is, for example, 0.5 μm to 5 μm.

The matte colored layer 3 includes a matting agent, a colorant, and a binder resin, and various additives as necessary.
The matting agent is not particularly limited as long as it has a matting action, and examples thereof include organic particles such as acrylic beads, hollow acrylic beads, and melamine resin; inorganic particles such as silica, alumina, calcium carbonate, and barium sulfate. Is mentioned. These particles can be used alone or in combination of two or more. The average particle diameter of the matting agent particles is, for example, 0.2 μm to 5 μm. The average particle diameter is a median diameter (D50) in a volume-based particle size distribution.

  The colorant imparts a desired color to the matte colored layer 3. The colorant is not particularly limited as long as it does not impair the light transmittance of the matte colored layer 3, and a conventionally known pigment or dye can be used. It is preferable to use a transparent colorant because the metal color of the metal-containing layer 4 provided on the back side can be seen well from the outside of the cylindrical label. Transparent colorants include blue transparent pigments such as Victoria Blue Lake, metal-free phthalocyanine blue, phthalocyanine blue, fast sky blue and other blue pigments (cyan pigments) and Victoria Blue and other blue dyes (cyan dyes). Colorant: zinc yellow zinc chromate (zinc yellow), lemon yellow (barium chromate), naphthol yellow S, Hansa Yellow 5G, Hansa Yellow 3G, Hansa Yellow G, Hansa Yellow GR, Hansa Yellow A, Hansa Yellow RN, Hansa Yellow R, Benzine Yellow, Benzidine Yellow Permanent red colorants such as G, benzidine yellow GR, permanent yellow NCG, yellow pigments such as quinoline yellow lake and yellow dyes such as auramine (yellow dye); Red pigments (Magenta pigments) such as R, Brilliant Fast Scarlet, Brilliant Carmine BS, Permanent Carmine FB, Risor Red, Permanent Red F5R, Brilliant Carmine 6B, Pigment Scarlet 3B, Rhodamine Lake B, Rhodamine Lake Y, Alizarin Lake And a red transparent colorant such as a red dye (magenta dye) such as rhodamine. These colorants can be used alone or in combination of two or more in consideration of the color desired to be expressed by the matte colored layer 3. For example, when a blue transparent colorant is used, a matte colored layer 3 that exhibits a matte blue color is obtained.

The binder resin is not particularly limited, and examples thereof include thermoplastic resins such as polyester resins, polyvinyl chloride resins, polyvinyl acetate resins, cellulose resins, acrylic resins, and urethane resins. Binder resin can be used alone or in combination of two or more.
Examples of the additive include an anti-settling agent, a lubricant, a dispersion stabilizer, a filler, an antioxidant, an ultraviolet absorber, an antistatic agent, and a flame retardant.

The content of the matting agent is not particularly limited, but if it is too small, the matting effect is not sufficiently achieved, and if it is too much, it becomes whitish. Therefore, when the entire matting colored layer 3 is 100% by mass, 5 mass%-60 mass% are preferable, and 10 mass%-50 mass% are more preferable.
The content of the colorant is not particularly limited, but if it is too small, it does not exhibit a desired color, and if it is too large, only the color may be conspicuous and the metal color of the metal-containing layer 4 may not be visible, and the matte effect Since there exists a possibility of killing, when the whole matte coloring layer 3 is 100 mass%, 0.1 mass%-10 mass% are preferable, and 0.5 mass%-5 mass% are more preferable.

The method for forming the matte colored layer 3 is not particularly limited, and the matte colored layer 3 can be formed by applying a matte colored layer forming material to the film 2 by a known printing method, coating method or the like and solidifying the material.
The matte colored layer forming material contains the matting agent, the colorant, the binder resin, and optional additives, and may contain a solvent for dissolving them as necessary.
The solvent is not particularly limited, and acetates such as ethyl acetate, propyl acetate and butyl acetate; alcohols such as methanol, ethanol, isopropyl alcohol and butanol; ketones such as acetone and methyl ethyl ketone; hydrocarbons such as toluene A mixed solvent thereof and the like.
Since the matte colored layer 3 can be easily formed in a desired region, the matte colored layer 3 is preferably formed by applying a matte colored layer forming material by a known printing method.
The matte colored layer forming material can also be prepared, for example, by mixing an ink containing a matting agent and an ink containing a colorant in a required ratio.

(Metal-containing layer)
The metal-containing layer 4 is a layer having a metallic luster.
The metal-containing layer 4 is provided on the cylindrical inner side with respect to the matte colored layer 3. In other words, the matte colored layer 3 is provided on the cylindrical outer side than the metal-containing layer 4.
The stacking position of the metal-containing layer 4 is not particularly limited on the condition that the metal-containing layer 4 is provided on the cylindrical inner side of the matte colored layer 3. For example, the metal-containing layer 4 may be provided on the back side of the film 2, or may be provided between the surface of the film 2 and the matte colored layer 3.
Preferably, the metal-containing layer 4 is provided on the back side of the film 2. In this case, the metal-containing layer 4 may be provided directly on the back surface of the film 2 as shown in the figure, or although not particularly shown, a transparent resin layer is provided on the back surface of the film and the transparent resin is provided. A metal-containing layer may be provided on the back surface of the layer. Preferably, the metal-containing layer 4 is provided directly on the back surface of the film 2. By providing the metal-containing layer 4 directly on the back surface of the film 2, the adhesion between the metal-containing layer 4 and the film 2 can be improved as will be described later, and both are less likely to be peeled off at a microscale even if heat shrinking, etc. Good metallic luster without spots can be seen from the outside of the cylindrical label.
When the metal-containing layer is provided between the surface of the film and the matte colored layer 3, the metal-containing layer may be provided directly on the surface of the film, an arbitrary layer is provided on the surface of the film, and the surface of the layer A metal-containing layer may be provided, or a transparent resin layer may be provided on the surface of the metal-containing layer, and a matte colored layer may be provided on the surface of the resin layer (none of which is shown).

  The metal-containing layer 4 is laminated in a region where the matte colored layer 3 is provided. In other words, the matte colored layer 3 is laminated in a region where the metal-containing layer 4 is provided. The metal-containing layer 4 may be provided in a region of the same shape and size so as to overlap with the matte colored layer 3 in the thickness direction of the film 2, or overlap the matte colored layer 3 in the thickness direction of the film 2. Moreover, it may be provided in a region smaller or larger than the matte colored layer 3. Preferably, the metal-containing layer 4 is provided in a region of the same shape and the same size as the matte colored layer 3 in the thickness direction of the film 2, or overlaps the matte colored layer 3 and is more than the matte colored layer 3. It is provided in a small area, and more preferably, it is provided in an area that overlaps with the matte colored layer 3 and is smaller than the matte colored layer 3. By providing the metal-containing layer 4 in this way, the matte colored layer 3 overlaps the metal-containing layer 4 so as to cover the entire metal-containing layer 4 in the thickness direction of the film 2. The part does not protrude from the edge of the matte colored layer 3. For this reason, it can prevent that only the metallic color resulting from the edge part of the metal containing layer 4 is visible from the outer side of a cylindrical label.

Specifically, the metal-containing layer 4 is provided in a region surrounded by the upper edge 23a, the lower edge 24a, the second side end edge 22a, and the boundary line of the first side end portion 21 of the film 2. . In other words, the outer edge of the metal-containing layer 4 coincides with the boundary lines of the upper edge 23 a, the lower edge 24 a, the second side edge 22 a, and the first side edge 21 of the film 2. Therefore, the upper edge, the lower edge, the first side edge 41a, and the second side edge 42a of the metal-containing layer 4 are the upper edge 23a, the lower edge 24a, the boundary line of the first side end portion 21, and the first side edge 42a, respectively. It corresponds to the two-side edge 22a. The first side edge 41 a of the metal-containing layer 4 faces the first side end portion 21 in the immediate vicinity of the first side end portion 21 of the film 2. The metal-containing layer 4 may be provided in a solid shape in the entire region surrounded by the outer edge (the upper edge, the lower edge, the first side edge 41a, and the second side edge 42a) of the metal-containing layer 4. When the design print layer 7 is provided on the film 2, the region corresponding to the design print layer 7 is a window region in which the metal-containing layer is not provided in order to display the design print layer 7 clearly. Yes.
Further, the edge shape of the window region of the metal-containing layer 4 (the outer shape of the window region viewed from the thickness direction of the film 2) is the edge shape of the window region of the matte colored layer 3 (the window viewed from the thickness direction of the film 2). The matte colored layer 3 overlaps the entire metal-containing layer 4 and the edge X of the window region of the metal-containing layer 4 when viewed from the surface side of the film 2. When the edge of the window region of the metal-containing layer 4 and the edge of the window region of the matte colored layer 3 coincide with each other in the thickness direction of the film 2, Although there is a possibility that the metal color of the containing layer 4 may appear linear, the matte colored layer 3 overlaps the edge X of the window region of the metal-containing layer 4 as described above, so that the metal of the metal-containing layer 4 The color can be prevented from appearing linear.

The metal-containing layer 4 is a layer containing metal fine particles and exhibiting a metallic luster on the surface thereof.
The metal-containing layer 4 may be formed from a metal vapor-deposited film formed by a metal vapor deposition method, or may be formed from a layer obtained by applying a metal-containing layer forming material containing metal particles and solidifying it. Since the degree of metallic luster can be easily adjusted, the metal-containing layer 4 is preferably formed from a layer obtained by applying and solidifying a metal-containing layer forming material.
The metal-containing layer forming material contains fine metal particles and a binder resin, and various additives as necessary.
Examples of the metal fine particles include aluminum powder, silver powder, zinc powder, stainless steel powder, and nickel powder. It is also possible to use a metal fine particle paste in which metal fine particles such as aluminum powder are added to a solvent or a surface treatment agent. It is preferable to use aluminum powder (including aluminum powder paste) as the metal fine particles because it is excellent in brightness and is relatively inexpensive. The particle diameter of the metal fine particles is not particularly limited, but is preferably 1 μm to 30 μm because the metallic luster is substantially uniform over the entire surface of the metal-containing layer 4. The particle diameter of the metal fine particles is a median diameter (D50) in a volume-based particle size distribution. The particle diameter of the metal fine particles corresponds to the diameter when the metal fine particles are substantially spherical, and corresponds to the long diameter when the metal fine particles are scaly.
Examples of the binder resin and additive include those exemplified for the matte colored layer forming material.
In the metal-containing layer 4 made of the metal-containing layer forming material, the content of the metal fine particles is not particularly limited. However, in order to exhibit a good metallic luster, when the entire metal-containing layer 4 is 100% by mass, 3 It is from mass% to 30 mass%, preferably from 5 mass% to 20 mass%.
The metal-containing layer forming material contains fine metal particles, a binder resin, and optional additives, and may contain a solvent for dissolving them as necessary. Examples of the solvent include those exemplified for the matte colored layer forming material.
The metal-containing layer forming material can be applied by a known printing method, coating method, or the like, but since the metal-containing layer 4 can be easily formed in a desired region, the metal-containing layer forming material is applied by a known printing method, It is preferable to form the metal-containing layer 4.

(Design printing layer)
The design print layer 7 is a print layer on which various designs such as a product name, a pattern, a component display, and a cautionary note are represented. The design print layer 7 can be formed using a conventionally known printing ink.
The design print layer 7 may include an unpatterned one-color or unpatterned multicolor background print layer 72 on which the design display is not represented on the condition that the design layer 71 includes the design. That is, the design print layer 7 is composed of only the design layer 71 on which a design such as a product name is printed in various colors, or is composed of the design layer 71 and the background print layer 72. In each cross-sectional view, the design layer 71 is shown in black, and the background print layer 72 is shown in light ink.
The non-patterned background print layer 72 is provided on the back surface of the design layer 71 in order to make the design display of the design layer 71 stand out. The non-pattern background print layer 72 is colored, for example, a non-pattern white print layer, a non-pattern silver print layer, a non-pattern multi-color print layer in which a non-pattern silver color and a non-pattern white color are separately applied. Printing layer; transparent printing layer (transparent resin layer) made of a medium ink or the like. The non-patterned white background print layer can be formed by spot-coating colored ink containing a white colorant such as a white pigment in a solid form or in an appropriate place. The non-patterned silver background printing layer can be formed by spot-coating colored ink containing a silver colorant such as aluminum fine particles in a solid form or at an appropriate location. The non-patterned multicolor background printing layer can be formed by separately applying two or more kinds of colored inks. A transparent background printing layer can be formed by spot-coating ink (medium ink) that does not contain a colorant in a solid form or at an appropriate location.
By providing the non-patterned background print layer 72 colored white or silver, the design can be clearly seen.
Although the thickness of the design print layer 7 is not specifically limited, For example, about 1 micrometer-5 micrometers are preferable.

The design print layer 7 may be provided on the front surface side or the back surface side or both surface sides of the film 2, but is preferably provided on the back surface side of the film 2 from the viewpoint of preventing scratches.
The design print layer 7 may be provided directly on the back surface (or front surface) of the film 2 or a transparent resin layer is provided on the back surface (or front surface) of the film 2 and the back surface (or front surface) of the resin layer. May be provided. The design print layer 7 may be provided on substantially the entire film 2, or may be provided in a partial region of the film 2.
The design print layer 7 may be provided between the matte colored layer 3 and the metal-containing layer 4 or in a window region where the matte colored layer 3 and / or the metal-containing layer 4 is not provided. It may be provided. If the matte colored layer 3 is provided on the surface side of the design print layer 7, the display on the design print layer 7 may be difficult to see or look different colors. It is preferable that the matte colored layer 3 is not provided on the side. That is, the design print layer 7 is preferably provided in a region corresponding to the window region of the matte colored layer 3 (a region where the matte colored layer 3 is not provided). In addition, when the metal-containing layer 4 is provided on the back side of the design print layer 7, the background of the display represented in the design print layer 7 is a metal color, and the display may not be clearly visible. It is preferable that the metal-containing layer 4 is not provided on the back side of the design print layer 7. That is, the design print layer 7 is preferably provided in a region corresponding to the window region of the metal-containing layer 4 (a region where the metal-containing layer 4 is not provided).
In the illustrated example, the design print layer 7 is directly provided on the back surface of the film 2 in the window region of the metal-containing layer 4, which is a partial region of the film 2. The outer edge of the design print layer 7 substantially coincides with the edge of the window region of the metal-containing layer 4. Accordingly, the design print layer 7 has a larger area than the window area of the matte colored layer 3, and the matte color layer 3 overlaps the edge of the design print layer 7 when viewed from the outside of the cylindrical label. Yes.

(Supplementary coloring layer)
The supplemental colored layer 5 is a layer provided as necessary to prevent only the metal color of the metal-containing layer 4 from being visible from the outside of the cylindrical label 10.
The supplemental coloring layer 5 includes a coloring agent having the same color as the coloring agent contained in the matte coloring layer 3. In the present invention, the “same color” does not mean the same color number or the like, but means that the colors look the same on human vision.
The supplemental colored layer 5 is provided between the matte colored layer 3 and the metal-containing layer 4, and preferably provided between the back surface of the film 2 and the metal-containing layer 4 and at the second side end 22 of the film 2. It is provided in the belt-like region.
Specifically, the supplemental colored layer 5 is provided directly on the back surface of the film 2. The band-shaped region is a region extending in the vertical direction from the upper edge 23 a to the lower edge 24 a of the film 2, the region corresponding to the second side edge 32 a of the matte colored layer 3, and the second side end 22 of the film 2. Part or all of the above. A supplemental colored layer 5 is provided in the band-like region of the film 2. Preferably, the supplemental colored layer 5 is provided on a part of the back surface of the second side end portion 22 of the film 2 or on the entire back surface of the matte colored layer 3 including the second side edge 32a. More preferably, it is provided in a region corresponding to the edge Y including the second side edge 32a of the matte colored layer 3 and a part Z of the back surface of the second side end 22 of the film 2 as shown in the drawing. The supplementary colored layer 5 is provided in a strip shape extending in the vertical direction with a lateral width (Y + Z) extending on both sides in the lateral direction with reference to the region corresponding to the second side edge 32a of the matte colored layer 3. The lateral width of the supplemental colored layer 5 may be the same as the lateral width of the gap W described later when the cylindrical label is formed, but is preferably set larger than the lateral width of the gap W. The lateral width of the supplemental colored layer 5 and the lateral width of the gap W are the lengths in the lateral direction.

The supplemental colored layer 5 includes a colorant and a binder resin, and includes various additives as necessary. The colorant is not particularly limited as long as it is the same color as the color of the matte color layer 3, and may be the same as or different from the colorant contained in the matte color layer 3. Preferably, the same colorant as that of the matte color layer 3 is used as the colorant of the supplemental color layer 5.
The thickness of the supplemental colored layer 5 is not particularly limited, and is, for example, 0.5 μm to 5 μm.
The formation method of the supplemental coloring layer 5 is not specifically limited, The method similar to the formation method of the matte coloring layer 3 is mentioned. In a simple method, for example, the supplementary colored layer 5 can be formed by preparing a material obtained by removing the matting agent from the components of the matting colored layer forming material and applying it to the film 2 by a printing method.

  The supplemental coloring layer 5 may contain a matting agent. For example, the supplemental coloring layer 5 may include a matting agent as exemplified in the matting coloring layer 3 and a coloring agent having the same color as the coloring agent contained in the matting coloring layer 3. Such a supplementary colored layer 5 can be formed using, for example, the matte colored layer forming material. However, since at least the matte colored layer 3 exists on the surface side of the supplementary colored layer 5 provided between the matte colored layer 3 and the metal-containing layer 4, the matting agent is contained in the supplemental colored layer 5. Even so, the matting effect is not obvious. For this reason, it is preferable that the supplementary coloring layer 5 does not contain a matting agent from a cost-effective viewpoint.

(Overcoat layer)
The overcoat layer 6 is a layer constituting the outermost surface of the substrate 1 (the outermost surface of the cylindrical label 10), and is provided as necessary to protect the matte colored layer 3 and the like.
The overcoat layer 6 may be provided on the entire surface side of the film 2, but preferably the overcoat layer 6 is not provided on the entire surface side of the film 2 and is overlaid on the matte colored layer 3. Are stacked. Moreover, the overcoat layer 6 may be provided also in the window area | region of the matte coloring layer 3, or does not need to be provided in the said window area | region.
In the illustrated example, the overcoat layer 6 is provided so as to overlap the surface of the matte colored layer 3 and the film surface of the window region. Accordingly, the overcoat layer 6 is formed by the boundary lines of the upper edge 23a, the lower edge 24a, the first side edge 21a, and the second side edge 22 of the film 2 (the second side edge 32a of the matte colored layer 3). It is provided in the entire enclosed area.

The overcoat layer 6 can be formed by applying a coating agent and solidifying it.
Examples of the coating agent include a solvent volatile coating agent containing a solvent and a resin, and a curable coating agent containing a curable resin that cures under predetermined conditions. As a coating method of the coating agent, a known printing method, coating method or the like can be used.
Although the thickness of the overcoat layer 6 is not specifically limited, For example, they are 1 micrometer-10 micrometers.

(Inner layer)
The inner surface layer 8 is a layer constituting the outermost back surface (the innermost inner surface of the cylindrical label 10) of the base material 1, and is provided as necessary to improve the slipperiness of the cylindrical label 10.
The inner surface layer 8 may be provided on the entire back surface of the film 2, but preferably the inner surface layer 8 is not provided on the entire back surface side of the film 2 and is laminated on the metal-containing layer 4. Yes. The inner surface layer 8 may be provided also in the window region of the metal-containing layer 4 or may not be provided in the window region.
In the illustrated example, the inner surface layer 8 is provided so as to overlap the back surface of the metal-containing layer 4 and the film back surface of the window region. Therefore, the inner surface layer 8 is surrounded by the upper edge 23a, the lower edge 24a, the second side edge 22a, and the boundary line of the first side edge 21 (the first side edge 41a of the metal-containing layer 4). It is provided throughout the area.

The inner surface layer 8 may be transparent or opaque.
The transparent inner surface layer 8 can be formed using, for example, an ink that does not contain a colorant (generally called a medium ink). The opaque inner surface layer 8 can be formed using an ink obtained by adding a white pigment such as titanium oxide to the medium ink. Further, the inner surface layer 8 may contain a lubricant such as waxes in order to improve slipperiness.
Although the thickness of the inner surface layer 8 is not specifically limited, For example, they are 1 micrometer-10 micrometers.

(Cylindrical label)
Adhesive, pressure-sensitive adhesive, or solvent (hereinafter referred to as adhesive, pressure-sensitive adhesive, or solvent) is attached to at least one of the back surface of the first side end portion 21 and the surface of the second side end portion 22 of the substrate 1 for label formation. The label-forming substrate 1 is rolled into a cylindrical shape, and the back surface of the first side end portion 21 is overlaid on the surface of the second side end portion 22, and the superposition is performed. A cylindrical label 10 as shown in FIG. 6 is obtained by forming the seal portion 9 by adhering all or part of the portion via the adhesive or the like. In addition, a solvent can be used when the film 2 is a material which can be solvent-bonded. Since the back surface of the first side end portion 21 and the surface of the second side end portion 22 are both film surfaces, it is possible to form the firmly bonded seal portion 9. In the seal portion 9, as shown in FIG. 7, the tip end portion of the second side end portion 22 of the label forming substrate 1 located on the inner side extends from the seal portion 9 in the circumferential direction and is on the first side. The margin of margin 25 overlaps the first side edge 41a of the metal-containing layer 4 on the end side. In other words, by bonding a part of the second side end 22 to the first side end 21 and non-bonding the other part to the first side end 21, the second side end 22 is A surplus margin (free end) that is not bonded to the first side end portion 21 between the second side end edge 22a and the edge of the seal portion 9, and is the first side end in the thickness direction. A surplus margin 25 that overlaps the first side edge 41a of the metal-containing layer 4 on the part side is provided. The metal-containing layer 4 and the inner surface layer 8 are also provided on the back side of the remainder 25. The lateral width (lateral length) of the margin 25 is such that the second side edge 22a coincides with the first side edge 41a of the metal-containing layer 4 on the first side end 21 side or the first side edge 41a. Preferably, the second side edge 22a is set so as to exceed the first side edge 41a of the metal-containing layer 4 on the first side edge 21 side. The width of the margin of margin 25 is, for example, about 3 mm to 7 mm. Since the metal-containing layer 4 is also provided on the back surface of the surplus margin 25 and the surplus margin 25 overlaps the first side edge 41a of the metal-containing layer 4, the first side including the seal portion 9 is included. Since the metal-containing layer 4 also continues in the circumferential direction when viewed from the outside of the cylindrical label 10 in the region A between the end edge 21a and the second side end edge 22a, brightness and texture due to moderate metal luster Have

In the base material 1, the first side edge 31 a of the matte colored layer 3 is the first side edge 31 a of the film 2, and the second side edge 32 a of the matte colored layer 3 is the second side of the film 2. It is located at the boundary line of the side end 22. Therefore, when the base material is formed into a cylindrical shape, theoretically, the first side end portion of the base material and the second side edge of the base material are arranged so that the first side edge and the second side edge of the matte colored layer are attached with no gap. The side end portions can be bonded to form a seal portion. However, since the cylindrical label is obtained by a mechanical manufacturing process, the first side end and the second side are accurately aligned so that the first side edge and the second side edge of the matte colored layer are in contact with each other. It is difficult to overlap and bond the side ends. Therefore, normally, as shown in FIG. 7, in the seal portion 9 of the cylindrical label 10, the first side edge 31 a and the second side end portion 22 of the matte colored layer 3 existing at the first side end portion 21 are provided. A gap W is formed between the existing second side edge 32a. Such a gap W is formed in a band shape elongated in the vertical direction in the vicinity of the seal portion 9. Since the matte colored layer 3 does not exist in the gap W, the metal color of the metal-containing layer 4 appears in an elongated strip shape when viewed from the outside of the cylindrical label 10.
In this regard, the matte colored layer 3 located at the first side end 21 is formed by forming the cylindrical label using the base material 1 in which the supplementary colored layer 5 is provided in the band-shaped region of the film 2 as described above. The supplemental colored layer in the band-like region of the second side end 22 including a corresponding region between the first side edge 31a and the second side edge 32a of the matte colored layer 3 located at the second side end 22 5 is disposed. By providing the supplemental coloring layer 5 in such a band-like region, the color of the supplemental coloring layer 5 can be seen from the gap W, so that it is possible to prevent the strip-like metal color from being seen.
The supplemental colored layer 5 may be provided at least in a region corresponding to the area between the first side edge 31a and the second side edge 32a of the erased colored layer 3.

The cylindrical label 10 of the present invention is provided with a matte colored layer 3 containing both a matting agent and a colorant outside the metal-containing layer 4. When the cylindrical label 10 is viewed from the outside, it has a brightness due to a moderate metallic luster and a calm texture. In this respect, the cylindrical label using the base material in which the matte layer and the colored layer are separately formed and laminated on the metal-containing layer has an appropriate brightness and texture like the cylindrical label 10 of the present invention. I know I don't have it. The reason why the cylindrical label 10 of the present invention has the above-described appearance is not clearly understood, but the present inventors presume as follows.
That is, when the cylindrical label in which the matting layer containing the matting agent and the coloring layer containing the coloring agent are separately formed is viewed from the outside, the color of the coloring agent can only be seen through the matting layer. The impression is whitish. As in the present invention, a cylindrical label in which a layer containing a matting agent and a colorant (matte coloring layer) is formed, the matting agent moderately blurs the color of the colorant. Combined with the layers, it is presumed to give the viewer a moderate metallic luster and calm texture.

In addition, in the seal part 9, as shown in FIG. 7, the second side end part 22 provided with the metal-containing layer 4 overlaps the first side edge 41 a of the metal-containing layer 4. Also, the metal-containing layer 4 is located on the back side of the matte colored layer 3. For this reason, the cylindrical label 10 becomes the external appearance which has the brilliance and calm texture resulting from the said moderate metal luster over the perimeter.
The cylindrical label 10 of the present invention is used by being attached to various adherends. The adherend is not particularly limited, but is typically a container in which beverages, seasonings, cosmetics, shampoos, and the like are stored. In particular, by attaching the cylindrical label 10 of the present invention to a relatively expensive product such as cosmetics, the product value can be increased by matching the image of the expensive product.
The method of attaching the cylindrical label 10 to the adherend is the same as that of the prior art.
