Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin leaf body and a method for producing the same, and more particularly to a thin leaf body which exhibits a variety of unique design effects and can be incinerated as it is when the base material is paper. At the same time, it can also be made into recycled paper,
Further, the present invention relates to a thin leaf body whose surface can be subjected to printing, and a method for producing the thin leaf body by a transfer method.

[0002]

2. Description of the Related Art As represented by Al-deposited paper, a thin sheet composed of a paper or resin sheet as a base material and a thin metal layer formed on the surface thereof by, for example, a vacuum deposition method to form a composite is made of various types. It is widely used in the fields of wrapping paper, wallpaper for interiors, book covers, Christmas cards, and various labels.

[0003] In the above-mentioned thin leaf, even if the base material is a paper or a resin sheet, the surface of the thin leaf is a mirror surface having a metallic luster, or the matte pattern having a metallic luster on the surface. Known are those having a (matte pattern), those having a metallic glossy hairline pattern on the surface, those having an embossed pattern on the surface, and those having a hologram pattern on the surface. Further, there is also a metal luster pattern obtained by combining the above-described patterns in a plane.

[0004] Such a thin leaf is usually produced as follows. First, in the case of a thin body having a mirror surface,
A thin resin is applied to the surface of a base material, and a metal such as Al is directly applied on the resin by a vacuum evaporation method or a sputtering method to form a thin metal layer. At this time, the thickness of the thin metal layer is usually required to be 50 nm or more in order to make the formed thin metal layer exhibit a mirror gloss having a metallic color tone.

In the case of a thin body having a matte pattern, a metal sheet having a matte pattern formed on one side is prepared in advance, and a base material is laminated on the back surface of the metal sheet via an adhesive. It is usually manufactured. In the case of a thin leaf having a hairline pattern, it is manufactured by preparing a metal sheet having a hairline pattern formed on one side in advance, and laminating a base material on the backside with an adhesive. Also, once a release agent is applied to the surface of the resin sheet on which the hairline pattern has been formed in advance, a metal thin layer is formed by, for example, vacuum depositing a metal on the release agent. Then, after applying a hot-melt adhesive on the thin metal layer, a base material is disposed thereon, and after performing a hot stamping process, the metal sheet is peeled off from the resin sheet to remove the thin metal layer. Is sometimes transferred to the base material side.

[0006] In the case of a thin leaf having an embossed pattern, it is manufactured by laminating a metal sheet and a base material and then embossing the metal sheet with fine irregularities. The metal sheet used in the production of the above-mentioned matte, hairline, and embossed thin sheets may be wrinkled or broken during handling if the sheet is too thin. Approximately 20 μm is used.

Further, in the case of a hologram-patterned thin leaf,
Generally, it is manufactured as follows. For example, a release agent is applied to one side of a resin sheet, and a protective layer is further formed,
After forming a thermoplastic resin layer on it, the surface of the thermoplastic resin layer is engraved by heating and pressing a hologram pattern, and further, for example, aluminum is deposited thereon, and then
It is manufactured by adhering a deposition surface of aluminum to a substrate and then peeling off a resin sheet.

[0008]

By the way, as a recent tendency, the taste of general consumers has been individualized,
As a result, it has come to demand that the products purchased by oneself have unique and novel design effects. Considering this from a manufacturer's point of view, there is a need for the development of a product that exhibits a design effect that is differentiated from other products.

In this case, the simplest method for exhibiting a new design effect on the thin leaf having various surface patterns described above is to print the desired pattern on the surface of the thin leaf by changing the pattern of the thin leaf itself. A surface pattern formed by combining print patterns, for example, a thin leaf pattern at a printing position disappears, and a surface pattern at which the thin leaf pattern can be visually recognized at another position is formed.

However, since the surface pattern of the thin leaf body is formed of the thin metal layer as described above, even if printing is performed here, the pattern of the thin metal layer existing under the printed pattern is not easily erased. Therefore, there is a problem that a sufficient modification of the design effect does not always occur. The present invention solves such a problem, and provides a thin leaf body that can easily form various and unique patterns that are recently required and exhibits an unprecedented design effect, and a method for manufacturing the same. With the goal.

Further, in the case of a conventional thin sheet manufactured using a metal sheet, the thickness of the metal sheet is as large as about 6 to 20 μm, so that a large amount of metal is used. Therefore, it is not possible to incinerate the thin sheet itself. Have difficulty. Further, when it is to be reused as recycled paper, the thin sheet is immersed in, for example, an alkaline solvent dissolving an adhesive to separate the base material and the metal sheet, and only the base material is recycled.

Further, in the case of a conventional thin leaf body in which, for example, aluminum is directly deposited on a substrate by a vacuum deposition method, fine irregularities on the surface of the substrate are reproduced as they are. Therefore, in order to make the surface of the thin leaf body mirror-like, it is necessary to use a substrate having a considerably high surface smoothness as a substrate. For example, when a woven or nonwoven fabric or a substrate having a rough surface is used, it is difficult to produce a thin leaf having a smooth mirror surface.
In other words, the types of substrates that can be used to produce mirrored thin bodies are limited.

Further, when paper is used as the base material, the brightness of the formed mirror surface is determined by the method specified in Method 5 of JIS-Z-8741, though it depends on the film forming conditions, although it is a mirror surface. Is about 700%, and it is very difficult to make the gloss higher than, for example, 1000%. The present invention solves such a problem, and it is possible to easily form a target pattern using any type of base material, and the amount of metal used is extremely small. The thin body itself can be incinerated,
In the case of a thin body having a mirror-finished surface, the above-mentioned glossiness of the mirror surface is at a level of 1500% or more. Further, when the base material is paper, the thin body is It is an object of the present invention to provide a thin body which can be crushed and converted into recycled paper, and a method for producing the same.

[0014]

In order to achieve the above-mentioned object, in the present invention, an adhesive layer and a thin metal layer are laminated in this order on one or both surfaces of the base material or the entire surface or a part of the surface. The surface of the thin metal layer has a smooth mirror surface, a matte surface, a hairline pattern surface, an embossed surface, a hologram pattern surface, or an appropriate combination of these patterns.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a thin leaf of the present invention. First, the thin leaf body A will be described. FIG. 1 shows the basic layer structure of the thin leaf body A.
The thin leaf body A is composed of an adhesive layer 2 and a metal thin layer 3 on a substrate 1.
Are laminated in this order, and the thin metal layer 3 is
Has a laminated structure α adhered to the surface of the substrate 1 (one surface in FIG. 1) via

The surface 3a of the thin metal layer 3 has a smooth mirror surface, a matte surface, a hairline surface, an embossed surface, a hologram surface, or a part of which is, for example, a mirror surface. Is a surface of various patterns obtained by appropriately combining the above-described patterns in a planar manner, for example, a hologram pattern. Here, the substrate 1 is not particularly limited, and for example, the following materials can be used.

That is, paper made of natural pulp; synthetic paper made of, for example, polypropylene or polyethylene; polypropylene film, polyester film,
Polyethylene film, polycarbonate film, polyvinyl chloride film, polystyrene film, cellophane film, polyethylene naphthalate film, ethylene vinyl alcoholate film, polyacrylonitrile film, cellulose acetate butyrate film, nylon film, polyvinyl alcohol film, ethylene vinyl acetate Polymer film, aramid film, polyimide film, polyurethane film,
Resin film such as polymethyl methacryl film, polylactic acid film, polycaprolactone film; non-woven fabric made of pulp, synthetic resin, biodegradable plastic resin, etc .; aliphatic polyester resin; biodegradable plastic film made of starch etc .; various natural fibers Alternatively, a synthetic fiber woven fabric or the like can be used.

The substrate may be transparent or translucent, and may be colored or opaque containing the desired pigment. The adhesive layer 2 is made of the base material 1 described above.
And serves to bond and fix the thin metal layer 3 to the
It is composed of a cured resin adhesive capable of firmly bonding both the base material 1 and the thin metal layer 3.

The following can be used as such a resin adhesive. For example, any one of polyurethane resin, epoxy resin, and acrylic resin,
Or a two-part curable resin adhesive composed of a resin obtained by appropriately mixing two or more of these; an ethylene acrylamide-based resin;
Either one or more of ethylene vinyl acetate resin, ethylene acrylic copolymer resin, vinyl acetate resin, acrylic resin, solvent-free polyurethane resin, polylactic acid resin, polycaprolactone resin A one-part curable resin adhesive that is appropriately mixed; urethane acrylate resin, epoxy acrylate resin,
Any one of polyester acrylate resin, mono-, di-, tri-, or tetra-hexaacrylate resin, or an electron beam irradiation-curable resin adhesive obtained by appropriately mixing two or more thereof; and And an ultraviolet irradiation-curable resin adhesive made of an acrylate resin.

Incidentally, these resin adhesives may be blended with carbon black or other pigments, or may be blended with dyes or the like. If, for example, carbon black is blended with a transparent or translucent resin adhesive, the adhesive layer 2 becomes opaque black and can shield light.
The metal constituting the thin metal layer 3 is not particularly limited, but for example, Au, Al, Ag, Zn, Cu, Sn,
Si and the like can be given. Of these, Al is preferred in terms of price, ease of forming a thin metal layer during the later-described manufacturing process, and the fact that when the surface 3a is a mirror surface, the glossiness can be increased. .

This thin leaf A can be manufactured as follows. First, as shown in FIG. 2, the metal thin layer 3 deposited directly to the production of laminated sheet a ₁ on the surface 4a of the transfer resin film 4. As the resin film 4 at this time, one having at least one surface (one surface 4a in FIG. 2) having a pattern having a negative-positive relationship with the surface pattern of the target thin leaf body A is used. . Specifically, the surface becomes a smooth mirror surface, a matte pattern uneven surface, a hairline pattern uneven surface, an embossed pattern uneven surface, a hologram pattern uneven surface, or an uneven pattern surface obtained by appropriately combining these patterns. Is used.

The resin film 4 has a surface 4
Since the thin metal layer 3 formed on a is transferred to the base material side as described later, it is preferable that the thin metal layer 3 does not exhibit strong adhesion to the thin metal layer 3. . Specifically, a biaxially stretched polypropylene film without corona discharge treatment can be mentioned as a preferred example.
The method for forming the thin metal layer 3 is not particularly limited, but is preferably a physical film forming method such as a vacuum evaporation method, a sputtering method, or an electron beam method. In particular, when the thin metal layer is formed of Al, the vacuum evaporation method is preferable.

The thickness of the thin metal layer 3 is not particularly limited. However, if the thickness of the thin metal layer 3 is too large, it is not only irrelevant to the surface pattern of the thin leaf A to be manufactured, but also the amount of metal used is large. Therefore, it becomes uneconomical, and furthermore, it becomes impossible to incinerate the thin leaf body as it is. For this reason, at least a metallic color tone is developed, and at the same time, a thickness capable of drawing a target pattern,
Specifically, it is preferable to set the thickness to 20 to 100 nm.

[0025] Then, the a laminated sheet a ₁ and the substrate are integrated through an adhesive described above. That is, as shown in FIG. 3, a resin adhesive 2 ′ as described above is applied to the surface of the substrate 1, and before the adhesive 2 ′ is cured,
Superimposed on the laminated sheet a ₁ of the thin metal layer 3 side of the surface to produce a laminated sheet a ₂ to. Incidentally, the adhesive 2 'may be applied to the surface of the thin metal layer 3 of the laminated sheet a _1.

[0026] Then, the laminated sheet a ₂ for example with heating and pressed to cure the adhesive 2 '. When the used resin adhesive 2 'is of a two-liquid curing type, heat treatment is performed for a predetermined time. In the case the resin adhesive is of a and solventless type 1 component curing type pressure the adhesive to produce a laminated sheet a ₂ using in heated was state, is the temperature of the laminated sheet a ₂ pressure And then cooled after thermocompression bonding. Also, if the resin adhesive is of the emulsion type, after crimping of the laminated sheet a _2, for example, it is sufficient heat to scattering the solvent or water. When the adhesive is an electron beam irradiation curing type or an ultraviolet irradiation curing type, an electron beam, an ultraviolet ray or the like may be irradiated. However, when using an ultraviolet irradiation-curable type, a transparent base material is used, and ultraviolet irradiation is performed from the base material side.

As a result, as shown in FIG. 4, a laminated sheet in which the base material 1 and the thin metal layer 3 are bonded and fixed to each other via the adhesive layer 2 formed by curing the adhesive 2 '. a ₃
Is manufactured. Then, to peel off the resin film 4 from the laminated sheet a _3. Since the surface 4a of the resin film 4 and the thin metal layer 3 are merely in physical contact with each other, and the adhesion is extremely small compared to the adhesive strength between the thin metal layer 4 and the adhesive layer 2, In addition, only the resin film 4 is easily separated from the thin metal layer 3 without the thin metal layer 3 being separated from the adhesive layer 2. As a result, a laminated structure α composed of the adhesive layer 2 and the thin metal layer 3 is formed on the base material.
The thin leaf body A shown in FIG. 1 in which the surface 3a is exposed is obtained.

At this time, the surface 3a of the thin metal layer 3 is a surface having a mirror surface or various concavo-convex patterns on the surface of the used resin film 4 transferred in a negative-positive relationship. ing. FIG.
Shows the layer structure of the thin material A ₁ belonging to the series. The thin leaf body A ₁ has an adhesive layer 2 formed partially on a surface of a substrate 1 in a desired plane pattern, and a thin metal layer 3 is formed only on the adhesive layer 2. is there. That is, the thin metal layer 3 is formed on a partial surface of the substrate 1 in a desired plane pattern.

[0029] In this thin sheet when the body A _1, together with various patterns visible to the metal color on the surface 3a of the metal thin layer 3, one of the metal thin layer 3 itself is drawn to the substrate surface In this state, the other flat design effect is taken into consideration in addition to the design effect exhibited by the thin leaf body A itself shown in FIG. 1.

[0030] The thin material A _1, at the time of manufacture of the laminated sheet a ₂ in FIG. 3, was coated with a desired plane pattern of the adhesive 2 'to the substrate 1, the metal thin layer 3 side of the laminated sheet a ₁ therein After laminating the surfaces, the adhesive 2 ′ is cured, and the resin film 4 is peeled off. Incidentally, the adhesive 2 'may be applied in a desired pattern on the surface of the metal thin layer 3 of the laminated sheet a _1.

That is, when the resin film 4 is peeled off, the portion of the thin metal layer adhered to the adhesive 2 ′ on the adhesive plane pattern remains on the adhesive layer side and adheres to the adhesive plane pattern. This is because the portion of the thin metal layer that does not exist is removed together with the resin film, so that the thin metal layer remains on the substrate 1 in a pattern corresponding to the plane pattern of the adhesive layer.

[0032] have become what this thin material A, thin material A ₁ is the surface 3a of 3 both the thin metal layer is because a metal, printing method thereto is a limited. Therefore, in the present invention, as shown in FIG. 6, the surface 3a of the thin metal layer
Further, a thin sheet A ₂ on which a resin coating film 5 for imparting printability is formed.
Is provided. The resin coating film 5 forms a laminated structure α by peeling the resin film 4 from the laminated sheet a ₃ to produce, for example, a thin leaf A (A ₁ ). (FIG. 6). The thickness of the resin coating at this time is not particularly limited, and may be, for example, a thickness that fills the uneven pattern on the surface 3a of the thin metal layer 3.

The resin paint used for forming the resin coating film 5 may be any resin paint that can impart printability. Examples thereof include urethane resins, polyester resins, chlorinated vinyl acetate resins, and the like. Examples of the coating material include a resin coating made of a nitrified cotton resin, an acrylic resin, a polyamide resin, and a maleic acid resin, or a mixture of two or more of them. These paints are solvent type,
Any of an aqueous type and a water-soluble type may be used.

The thin leaf A ₂ on which the resin coating film 5 is formed can form a printed pattern of any color or pattern thereon, and the thin metal A of the thin leaf A (A ₁ ) can be formed thereon. In addition to the design effect of the surface itself, another design effect based on the printed pattern is exerted to achieve the design effect. The resin coating film 5 may be transparent or translucent, or may be colored by blending a pigment or the like.

When the resin coating film 5 is formed by blending transparent or translucent fine particles made of, for example, silicic anhydride, polyethylene resin, polyester resin, or the like into a resin coating, the surface of the resin coating film 5 has the fine particles. Of the resin coating film 5 due to the irregular reflection of light caused by the presence of these fine particles.
Is visually recognized. When a transparent resin is applied to the surface of the resin coating film 5 or a transparent cellophane tape or the like is applied, the matte tone of the portion disappears, and the surface pattern of the thin metal layer 3 is removed from there. Can be visually recognized, and a thin leaf body exhibiting an extremely unique design effect can be obtained.

Further, the resin coating 5 has a two-layer structure as shown in FIG. 7, for example, a transparent resin coating is applied to the entire surface of the thin metal layer, and then a colored resin coating is applied on the coating 5a. When the paint is applied in a desired plane pattern to form the colored coating film 5b, a thin leaf body that exhibits one design effect by itself can be obtained. By the way, the laminated sheet a _{1 in} FIG.
In the case where the surface 4a of the resin film 4 is assumed to have a very high smoothness, the surface of the thin metal layer 3 is in a mirror state reflecting the smoothness of the film surface as it is.

For this reason, the thin metal layer 3 has such a property that its surface (mirror surface) has a high glossiness, although its thickness is as thin as 20 to 100 nm. Specifically, the glossiness measured by the method specified in Method 5 of JIS-Z-8741 is 1000 to 2000%. In other words, even if the amount of metal used is small, the thin leaf has a mirror surface with a high surface gloss.

When the moisture permeability of the thin metal layer having a thickness of 20 to 100 nm is measured by the method specified in JIS-Z-0208, the value is 300 g / m ² · 24 hr or less. The above description is directed to the case where the laminated structure α of the adhesive layer and the thin metal layer is formed on one surface of the base material 1 in any of the thin sheets A, A ₁ and A _2. However, the present invention is not limited to this embodiment, and the above-described laminated structure α may be formed on both surfaces of the substrate 1.

When the above-mentioned laminated structure α is formed on one surface of the base material 1 and the protective sheet 1A is adhered to the back surface thereof via the pressure-sensitive adhesive layer 2A, the thin sheet becomes the protective sheet 1A.
After peeling off, it can be used, for example, as wallpaper having a unique design effect by sticking it to a wall or the like (FIG. 8). Next, the thin leaf body B and a method for producing the same will be described.

FIG. 9 shows the basic layer structure of the thin leaf body B.
The thin leaf body B has a laminated structure β in which an adhesive layer 2, a thin metal layer 3, and a resin layer 6 described later are laminated on a substrate 1 in this order. Here, as the base material 1 and the adhesive layer 2, the same materials as those of the thin leaf body A described above may be used. Further, the thin metal layer 3 is preferably an Al vapor-deposited layer as in the case of the thin-leaf body A, and has a thickness of 20 to
It is about 100 nm.

The surface 3a of the thin metal layer 3 may have a smooth mirror surface, a matte surface, a hairline surface, an embossed surface, a hologram surface, or a pattern obtained by appropriately combining these patterns. It is a surface,
The surface 6a of the resin layer 6 has a matte surface, a hairline pattern surface, an embossed pattern surface, a hologram pattern surface, or a pattern surface obtained by appropriately combining these patterns.

Therefore, in the case of the thin leaf body B, a pattern is also formed on the back surface 6b of the resin layer 6, and for example, the metal thin layer 3
If the surface 3a of the thin metal layer 3 is a mirror surface, the surface 3a of the thin metal layer 3 has a concave-convex pattern having a negative-positive relationship. Here, the resin layer 6 may be transparent or translucent to white light, or may be colored. Further, as in the case of the thin leaf A, a pigment may be blended.

When the resin layer 6 is transparent, for example,
From the entire surface of the thin leaf body B, a surface pattern having a metal color of the metal thin layer 3 located below the resin layer 6 and a pattern of the surface 6a of the resin layer 6 are combined, and A pattern that gives a three-dimensional effect can be visually recognized as the entire pattern. For example, when the surface 3a of the thin metal layer is a mirror surface and the surface 6a of the resin layer is a hologram pattern,
From the surface of the thin leaf B, a hologram pattern rich in three-dimensional effect shining in a metallic color can be visually recognized.

This thin leaf body B can be manufactured as follows. First, as shown in FIG. 10, for producing a laminated sheet b ₁ by forming a metal thin layer 3 of a desired thickness on the surface 4a of the first transfer resin film 4, for example by vacuum deposition. As the first resin film 4 used at this time,
The same material as the resin film used at the time of manufacturing the thin leaf member A may be used, and the surface 4a may be an uneven pattern having a negative-positive relationship with a target pattern formed on the surface of the thin metal layer.

Next, an adhesive is applied to the surface of the thin metal layer 3 of the laminated sheet b ₁ with a predetermined thickness, the base material 1 is pressed thereon, and the adhesive is cured by, for example, heat treatment. The first resin film is peeled. As a result, as shown in FIG. 11, the substrate 1 and the thin metal layer 3 are in close contact with each other via the adhesive layer 2, and the surface 3a of the thin metal layer is transferred to the surface 4a of the first resin film 4. Laminated sheet b ₂
Is manufactured. At this time, the above-described transfer operation may be performed by applying an adhesive to the surface of the base material.

On the other hand, as shown in FIG. 12, a second resin film 7 having a concave-convex pattern having a negative-positive relationship with the surface pattern of the thin leaf body B to be manufactured on the surface 7a is prepared. on the surface 7a, a viscous resin 6 'is uncured coated with a desired thickness to produce a laminated sheet b ₃ which is a material of the resin layer 6 to be formed. Then, the resin 6 'when the uncured state, as shown in FIG. 13, the resin 6 of the laminated sheet b ₃ to the surface 3a of the thin metal layer of the laminated sheet b ₂ described above' superposed surface side, for example to produce a laminated sheet b ₄ a whole by thermocompression bonding. In this process, the resin 6 ′ of the laminated sheet b ₃ adheres to the thin metal layer 3 and cures to become the resin layer 6.

[0047] Finally, to peel off the second resin film 7 in the laminated sheet b _4. As a result, a laminated structure β having the resin layer 6 in which the pattern of the surface of the second resin film is transferred to the front surface 6a and the pattern of the surface 3a of the thin metal layer 3 is formed to the back surface 6b is formed. The thin leaf body B shown in FIG. 9 is obtained. In the case of using the resin volume shrinkage rate during hardening is large as the resin 6 'is absorbed, the entire surface, for example, a polyester resin of the thin metal layer 3 of the laminated sheet b _2, a polyether resin, a volumetric shrinkage as polyurethane resin It is preferable to apply a soft resin to be formed by, for example, gravure printing, since the adhesion between the formed resin layer 6 and the thin metal layer 3 can be further enhanced.

FIG. 14 shows the layer structure of another thin body B ₁ belonging to the thin body B series. In the thin leaf body B ₁ , the thin metal layer 3 in the thin leaf body B is drawn on the base material 1 in a desired plane pattern, and this plane pattern is embedded in the resin layer 6. That is, in the thin material B _1,
The thin metal layer does not exist under the resin layer 6 as a single thin layer, but the thin metal layer or the adhesive layer corresponds to the plane pattern in a portion where the thin metal layer or the adhesive layer does not exist. Exist, and the portion also has a layer structure filled with the resin layer 6.

In the case of this thin leaf body B ₁ , the surface 6 of the resin layer 6
From a, the surface pattern of the resin layer can be visually recognized with a three-dimensional effect in the color tone of the thin metal layer 3 located thereunder, and at the same time, only the surface pattern of the resin layer exists, so that the thin leaf as a whole is obtained. It exerts a different design effect from that of the body B. The thin material B ₁ represents may be prepared as follows.

[0050] First, FIG. 15 as indicated by the laminated sheet b ₁ 'of the laminated sheet b ₁ by applying a' in the same plane pattern as the pattern to be formed on the surface of the metal thin layer 3 adhesive 2 in FIG. 10 To manufacture. Then, to cure the adhesive 2 'After attaching the the base material' adhesive 2 'the laminated sheet b _1, then peeled off the resin film 4. The portion of the thin metal layer 3 adhered to the adhesive 2 ′ remains as it is, and the other portion is removed together with the resin film 4. As a result, as shown in FIG. A laminated sheet b ₂ ′ in which the plane pattern of the thin metal layer 3 is partially transferred in the same plane pattern as the plane pattern ₂ ′ is manufactured.

Then, the laminated sheet b ₂ ′ is added to FIG.
In superposed laminated sheet b ₃ shown by peeling the resin film 7 After curing the resin 6 ', 14
Thin material B ₁ of is produced. Further, for the thin leaf B (B ₁ ), a resin coating film 5 for imparting printability is formed on the uneven surface 6a of the resin layer 6 as in the case of the thin leaf A, and FIG. it is preferable that the thin material B ₂ shown. A desired print pattern is further added to the pattern of the thin body itself,
This is because a more unique design effect can be exhibited.

In forming the resin coating film 5, it is necessary to apply the resin coating in a thickness that does not fill the uneven pattern on the surface 6 a of the resin layer 6. This is because if the resin paint is applied thickly to fill the uneven pattern, the obtained thin leaf body will not exhibit a unique design effect based on the surface pattern of the resin layer 6. In addition, this resin coating film 5
May have a single-layer structure as shown in FIG. 17, but may have a two-layer structure as in the case of the thin leaf member A.

Further, in the same manner as in the case of the thin leaf member A, the above-mentioned laminated structure β may be formed on both sides of the base material.
It may be formed on one side and a protective sheet may be stuck on the back side. The thin body B (B ₁ , B ₂ ) exhibits the following unique design effects. First, the surface 6 of the uneven pattern of the resin layer 6
When a print pattern is applied with, for example, a transparent ink so that a is buried, the pattern of the upper layer of the thin leaf body which has been visually recognized at that print point disappears, and only the color tone of the transparent lower metal thin layer is replaced. Can be visually recognized. This phenomenon similarly occurs when a transparent tape is stuck or drawn with magic ink of various colors.

Then, in the portion where the print pattern is not formed, the concavo-convex pattern as usual is visually recognized. That is, in the case of the thin leaf body B, it is possible to very easily exhibit a unique design effect that a desired pattern and a metallic color tone are mixed. Also, in the case of the thin leaf body B, even if characters and patterns are printed and drawn on the uneven surface of the resin layer 6 with, for example, a very thin line using transparent ink with a thickness that fills the uneven surface, it is necessary to judge these visually. It is difficult. However, when the printed and drawn portion is copied by, for example, an electronic copying machine, a unique effect is obtained in which the characters and designs printed and drawn are clearly copied on the obtained copy paper.

[0055] Furthermore, in the case of thin material B _1, when appropriately setting the pitch of the plane pattern and the metal absence portion of the thin metal layer 3, by changing the angle between the surface and the eyes of the uneven pattern , At a certain angle, the uneven pattern disappears,
At a certain angle, the uneven pattern may be seen intensely,
This is also one of the unique design effects of the thin leaf of the present invention.

FIG. 18 shows the layer structure of another thin body B ₃ belonging to the series of thin body B. The thin material B ₃ is the uppermost layer of the laminate structure β in thin material B shown in FIG. 9, i.e. on the surface of the resin layer 6, Al thin thickness 3~10nm via the adhesive layer 2B of the transparent or translucent The layer 3A is laminated. At least the surface of the Al thin layer 3A has a smooth mirror surface, a matte surface, a hairline pattern surface, an embossed resin surface, a hologram pattern surface, or a pattern surface obtained by appropriately combining these patterns. ing.

Since the thickness of the Al thin layer 3A is extremely thin as described above, the Al thin layer 3A becomes translucent. Since has the adhesive layer 2B also transparent or translucent located in the lower layer, from the surface of the thin material B _3, Al thin to slightly vividly visible and the design effect of visually recognized thin material B It is possible to obtain a unique visual in which the design effect of the layer surface is combined.

This thin leaf B ₃ has a thickness of ₃ to 10 nm.
The laminated sheet a ₁ shown in FIG. 2 comprising forming a l thin layer,
After being superposed on the surface of the thin leaf member B shown in FIG. 9 via a transparent or translucent adhesive, the resin film for transfer can be peeled off to produce the film. Next, the thin leaf body C and a method of manufacturing the same will be described.

FIG. 19 shows the basic layer structure of the thin leaf C. The thin body C does not include a thin metal layer unlike the thin bodies A and B, and has a laminated structure γ in which the resin layer 6 is directly laminated on the base material 1. And
The surface 6a of the resin layer 6 has an uneven surface of a matt pattern, an uneven surface of an embossed pattern, an uneven surface of a hairline pattern, an uneven surface of a hologram pattern, or an uneven surface of a pattern obtained by appropriately combining these patterns.

Here, the base material 1 and the resin layer 6 may be made of the same material as that of the thin leaf body B. This thin leaf C is obtained by applying an uncured and viscous resin as a material of the resin layer 6 to a desired thickness on the surface of a resin film having a desired uneven pattern formed on the surface, as shown in FIG. and manufacturing a laminated sheet b ₃ as, then, can the curing the resin-side surface and the resin then obtained by superimposing the substrate 1 is prepared by finally peeling off the resin film. The resin is cured in a state of being adhered to the base material 1 and becomes the resin layer 6 and moves to the base material side, and the surface thereof is a surface transferred in a negative-positive relationship with the uneven pattern of the resin film.

In the case of the thin leaf C, similarly to the case of the thin leaf B, a resin coating film for imparting printability is formed on the surface 6a of the uneven pattern of the resin layer 6 with a thickness not embedding the uneven pattern. It is preferable to form a film. The resin layer 6 may be transparent or translucent, and may be colored by blending a pigment or the like. In this thin leaf body C,
When the resin layer 6 is transparent or translucent, the surface 6a
When touching the hand, a peculiar phenomenon that the pattern of the touched portion disappears due to the influence of the oil or moisture easily occurs. But,
When the resin layer 6 is colored, such a phenomenon hardly occurs.

Further, when a resin coating film for imparting printability is formed on the surface of the thin leaf body C and a printing pattern is imparted thereon,
Depending on the angle of the line of sight, a feeling that the printed pattern moves can be obtained. In the case of the thin body C, the thin body B ₃
Similarly to (FIG. 18), an Al thin layer having a thickness of 3 to 10 nm may be formed on the laminated structure γ via a transparent or translucent adhesive layer.

Next, the thin-leaf body D and its manufacturing method will be described. FIG. 20 shows the basic layer structure of the thin leaf body D. The thin leaf body D has a laminated structure δ in which two resin layers 6A and 6B are laminated on the base material 1. The lower resin layer 6A is made of a colored resin, and the upper resin layer 6A is made of a colored resin. 6B is made of a transparent or translucent resin.

Then, the lower resin layer 6A is drawn on the base material 1 in a desired plane pattern.
It is buried in B. Therefore, the upper resin layer 6
From the surface of B, the lower resin layer 6B drawn and colored in a desired pattern can be visually recognized. Surface 6a ₁ of the lower resin layer 6A is made smooth mirror surface, the surface of the matte pattern, the surface of the hairline pattern, the surface of the embossed pattern, the surface of the hologram pattern or the surface of the appropriate combination patterns of these patterns, ing. The surface 6a ₂ of the upper resin layer 6B is made the surface of the matte pattern, the surface of the hairline pattern, the surface of the embossed pattern, the surface pattern in combination to the surface of the hologram pattern, or these patterns appropriate .

This thin leaf D can be manufactured as follows. First, on the surface of the first transfer resin film 4 having a surface pattern in a negative-positive relationship with the surface pattern of the lower resin layer 6A, the same plane as the pattern of the lower resin layer to be formed on the base material is used. Uncured colored resin 6 'with pattern
It is applied to produce a laminated sheet d ₁ (FIG. 21).

Then, after the surface of the laminated sheet d ₁ on the side of the colored resin 6 ′ is overlapped with the substrate 1, the colored resin 6 ′
Is cured to form a resin layer adhered to the substrate 1, and the first transfer resin film is peeled off. As a result, as shown in FIG. 22, on the substrate 1, the surface pattern and a negative of the resin film 4 - has a surface pattern 6a ₁ on the relationship between the positive and draws a plane pattern which desired the entire It has been that the resin layer 6A is has been base sheet d ₂ transfer is obtained.

On the other hand, a transparent or translucent uncured resin 6 ″ is applied to the surface of the second transfer resin film 7 having a surface pattern in a negative-positive relationship with the surface pattern of the upper resin layer 6B. preparing a laminated sheet d ₃ Te (Figure 23).
When the resin 6 ″ is in an uncured state,
As shown in 4, and curing the resin 6 'is made transparent or semi-transparent resin layer 6B mixture was allowed here superimposed surface of the colored resin layer 6A side of the laminated sheet d _2, to produce a laminated sheet d ₄ .

Finally, the laminated film δ is formed by peeling the resin film 7 from the laminated sheet d ₄ and transferring the resin layer 6B to the base sheet side, thereby producing the thin leaf body D shown in FIG. You. In addition, in the case of the thin leaf D, similarly to the case of the thin leafs B and C described above, the upper resin layer 6 is formed.
It is preferable that the resin film for printability imparted a thickness that does not embedded the pattern onto the surface pattern 6a ₂ of B to be granted the formed printing pattern. When forming the upper resin layer or the lower resin layer, a pigment or the like may be blended in the uncured resin used. Furthermore, as in the case of thin material B _3, it may be formed Al thin layer having a thickness 3~10nm through the transparent or translucent adhesive layer on the stacked structure [delta].

In the thin leaf D, a colored pattern formed by the plane pattern itself of the lower resin layer 6A can be visually recognized from the entire surface. Then, the transparent or translucent surface pattern of the upper resin layer 6B overlaps and is visually recognized on the colored surface pattern of the lower resin layer 6A. As a whole, these three types of patterns are three-dimensional. The unique design effect of being visually recognized in combination with the above is obtained.

For example, if the lower resin layer 6A is made black by blending carbon black or the like and the pitch between the patterns is appropriately selected, a black pattern having a three-dimensional effect fluctuates from the entire surface depending on the viewing angle. It has a design effect that looks like Next, the thin leaf body E and a method for producing the same will be described. FIG. 25 shows the basic layer structure of the thin leaf body E. This thin body has a laminated structure ε having the same layer structure as that of the thin body A shown in FIG. However, substrate 1
Is made of a transparent or translucent material, and the adhesive layer 2 is also made of a transparent or translucent resin.
A is an essential requirement that it be formed of an Al thin layer such as an Al vapor-deposited layer having a thickness of 3 to 10 nm.

With such a configuration, the thin leaf body E is translucent in the thickness direction. Where Al
The surface 3a of the thin layer 3A may be a smooth mirror surface, a matte pattern uneven surface, a hairline pattern uneven surface, an embossed pattern uneven surface, a hologram pattern uneven surface, or a pattern obtained by appropriately combining these patterns. can do. In this case, the back surface of the laminated structure ε can be seen through the translucent state.

[0072] Further, the surface of the thin metal layer 3A, as in the case of thin material A _2, a resin coating film for printability imparted 5
Is formed, and a printing pattern is added thereon using a transparent ink, so that another design effect can be exhibited.
At this time, when a backlight is provided, a design effect that these printed patterns are floated and visible can be obtained. The method of manufacturing the thin leaf E is the same as the method of manufacturing the thin leaf A,
_When forming the Al thin layer in Step ₁ , the thickness is 3 to 10 nm.
, And the process can be performed in the same manner as the method of manufacturing the thin leaf member A, except that a transparent or translucent material is used for both the adhesive and the base material.

[0073] In the case of this translucent thin material, as shown in FIG. 26, it is also possible to make Al thin layer 3A in thin material E ₁ a partially formed on the substrate 1. FIG. 27 shows the layer structure of another thin body E ₂ belonging to the series of thin body E. This thin leaf E ₂ is the uppermost layer of the laminated structure ε in the thin leaf E,
That is, the transparent or translucent resin layer 6C is formed on the Al thin layer 3A. And the resin layer 6C
Is a smooth mirror surface, a matte surface, a hairline surface, an embossed surface, a hologram surface, or a surface obtained by appropriately combining these patterns.

This thin leaf body E ₂ is composed of the surface of the lower layer 3 and the upper layer 6.
The design effect differs from that of the thin-leafed body E, such that the pattern changes due to the slight interference of the surfaces of C and the back surface can be seen through. This thin sheet E ₂ is formed by laminating a laminated sheet b ₃ as shown in FIG. 12 manufactured using a transparent or translucent adhesive with the laminated structure ε of the thin sheet E shown in FIG. After curing, the resin film for transfer can be peeled off to produce the film.

[0075] Incidentally, as in the case of thin material B _3, may be formed Al thin layer having a thickness 3~10nm through the transparent or translucent adhesive layer on the stacked structure epsilon. Next, the thin leaf body F and a method of manufacturing the same will be described. This thin leaf F
Is the surface of each of the laminated structures α, β, γ, and δ in the thin bodies A, B, C, and D, that is,
The thin metal layer is partially formed via an adhesive.

For example, in the case of the thin leaf F shown in FIG. 28,
A thin metal layer 9 is partially formed in a desired plane pattern on the surface of the thin leaf body B shown in FIG. 9 with an adhesive layer 8 interposed therebetween. As a whole, the adhesive layer 2 and the metal A laminated structure 成 る composed of the thin layer 3, the resin layer 6, the adhesive layer 8, and the thin metal layer 9 is formed. Therefore, in the case of the thin leaf body F, the surface pattern 6a of the resin layer 6 and the pattern in which the surface pattern of the thin metal layer 9 is drawn by the plane pattern of the thin metal layer are visually recognized in a mixed state.

This thin leaf body F is manufactured as follows. First, for example, a thin leaf body B is manufactured by the method described above. On the other hand, a thin metal layer is deposited on the surface of the transfer resin sheet in which a predetermined pattern is formed on the surface, to produce a laminated sheet f ₁ of the same structure as the laminated sheet a ₁ shown in FIG. Then, as shown in FIG. 29, an adhesive is applied to 8 'in a desired plane pattern on the surface of the thin material B, and adhesively arranged a laminated sheet f ₁ of the thin metal layer 9 side surface of thereon. Thereafter, the adhesive 8 ′ is cured to form an adhesive layer, and the transfer resin film 4 is peeled off.

As a result, the portion of the thin metal layer 9 adhered to the adhesive 8 ′ remains on the thin leaf member B, and the portion of the thin metal layer 9 not adhered to the adhesive 8 ′ together with the resin film 4. Since it is removed, a thin leaf F having the laminated structure ζ shown in FIG. It should be noted that the transfer resin film used in the production of each of the above-mentioned thin leaf bodies does not end its service life at one time, and can be used a plurality of times. However, when the number of uses increases, the film is stretched, and the appearance quality of a pattern formed upon transfer deteriorates. Therefore, the number of uses differs depending on the type of the pattern, but is generally 2 to 10 times. It is about.

[0079]

Example 1 A thin leaf A having a mirror-finished surface was manufactured as follows. First, an Al thin layer having a thickness of 25 to 30 nm was formed on one surface of a biaxially stretched polypropylene film having a smooth surface without being subjected to corona discharge treatment by a vacuum evaporation method.

Then, a two-component curable polyurethane-based resin adhesive is applied to the entire surface of the Al thin layer by a gravure coater to a thickness of 4 to 4 μm.
After coating so as to have a thickness of 6 μm, the solvent was scattered by a drier, and the coated paper was overlaid on the coated paper and passed through a heated nip roller (temperature: 40 ° C.) to adhere them. In addition, temperature 4
After leaving the resin adhesive in an atmosphere of 0 ° C. for about 24 hours to cure the resin adhesive, the biaxially stretched polypropylene film was peeled off.
The thin layer was transferred to coated paper to obtain thin leaf A shown in FIG. The surface was a very glossy silver mirror.

For comparison, a resin was applied on the same coated paper to a thickness of 2 to 3 μm by a gravure coater, and then the solvent was scattered by a dryer.
Was vacuum-deposited to form an Al-deposited layer having a thickness of 40 to 50 nm to produce a normal aluminum-deposited paper. JIS for both
The glossiness of the surface and the moisture permeability in the thickness direction were measured by the method 5 of -Z-8741 and the method specified in JIS-Z-0208.

The glossiness and the moisture permeability of the thin leaf body A were respectively
^{1600~1650%, 150~190g / m 2 ·} 24h
It was the value of r. However, in the case of the aluminum deposited paper of the comparative example, 650 to 800% and 120 to 200 g /
m was ² · 24hr. After the corona discharge treatment on the mirror surface of the thin leaf body A, 5% by weight of fine particles of silica anhydride having a particle size of 0.1 to 5 μm were added to a resin paint for imparting printability comprising a urethane resin and a nitrified cotton resin. The paint was applied to form a coating film. The portion where the coating film was formed became matte (matte), and the portion where the coating film was not formed remained the mirror surface, and a surface pattern in which the mirror surface and matte tone (matte) were mixed was formed. Then, when a transparent cellophane tape was stuck to the matte (matte) portion, the portion returned to the mirror surface again.

Example 2 Under the same conditions as in Example 1, the thin leaf A shown in FIG. 1 was produced. A corona discharge treatment is performed on the surface of the Al thin layer 3 of the thin leaf body A, and a transparent resin paint (1) for imparting printability comprising a urethane resin and a nitrocellulose resin is applied thereto by a gravure coater, and the thickness is reduced to 0. 05Myuemu, thickness 0.2 [mu] m, and 3 types produce thin material a ₂ as shown in FIG. 6 having a resin coating film 5 having a thickness of 1 [mu] m.

The adhesion strength of each coating film to the Al thin layer was substantially the same, and the thinner the coating film 5, the better the golden gloss from the surface. On the other hand, the above transparent resin paint (1)
5% by weight of yellow pigment, particle size of silicic anhydride 0.1-5μ
The resin coating material (2) was prepared by blending 5% by weight of m particles. Then, the resin coating was applied to the entire surface of the resin film 5 of the above-described thin material A _2. As a result, the coated surface changed to a slightly matte yellow matte surface with a metallic luster.

Further, on this surface, a red paint, a blue paint, a yellow paint, and a transparent varnish were printed by a UV offset printing machine so as not to overlap each other. As a result, at the place where the transparent varnish was printed, the matte feeling disappeared and a mirror-like yellow metallic luster was visually recognized, and at the place where another colored paint was printed, the metallic luster of each color was visually recognized.

[0086] was repeated except for using the biaxially stretched propylene film without corona discharge treatment on one surface hologram pattern Example 3 is formed, in the same manner as in Example 2, to produce a thin material A _2, The resin coating (2) used in Example 2 was applied instead of the transparent resin coating (1) to form a resin coating.

Although a yellow metallic glossy hologram pattern was slightly visually recognized from the surface of the obtained thin leaf body, it was in a matte state as a whole. Further, a red paint, a blue paint, a yellow paint, and a transparent varnish were printed on the surface of the mat pattern by a UV offset printing machine so as not to overlap each other. As a result, the matte feeling disappeared at the place where the transparent varnish was printed, and the yellow hologram pattern with metallic luster was clearly visible, and at the place where other colored paint was applied, the metallic luster of each color was visible. Was done.

Example 4 One side of a biaxially stretched polypropylene film having a smooth surface, which had not been subjected to corona discharge treatment, was first scratched with a brush roller to form a hairline pattern, and was further pressurized and heated there. A hologram pattern was formed to produce a transfer resin film (1).

Conversely, a hologram pattern is first formed on one surface of the biaxially stretched polypropylene film by a heating and pressing method, and a hairline pattern is further formed thereon by a brush roller method to form a transfer resin film (2). Was manufactured. Further, two types of hologram patterns 4A and 4B each having a rectangular shape of about 18 mm in length and about 18 mm in width were formed on one surface of a biaxially stretched propylene film that had not been subjected to corona discharge treatment by a pressure heating method. A transfer resin film (3) having a smooth surface 4C alternately formed was manufactured.

Using these three types of transfer resin films (1), (2) and (3), a thin leaf A was produced in the same manner as in Example 2. Then, the transparent resin coating material (1) used in Example 2 was applied to the surface of the thin leaf body A with a gravure coder so as to have a thickness of 0.4 μm to form a resin coating film for imparting printability.

On the surface of the thin leaf manufactured using the film (1), a thin metallic gloss hairline pattern was visually recognized in the metallic gloss hologram film, and on the surface of the thin leaf using the film (2). A thin metallic gloss hologram pattern is visually recognized in the metallic gloss hairline pattern, and a rectangular mirror surface is formed on the surface of the thin leaf body using the film (3), like the two rectangular hologram patterns 4A and 4B. 4C
And were visually recognized in a mixed state.

Example 5 A thin sheet A was produced in the same manner as in Example 2 except that thin high-quality paper was used instead of coated paper. A light source was placed on the high-quality paper side of the thin leaf body, and the surface was visually observed from the Al thin layer side. As a result, the brightness of the light source could be visually recognized.

Thus, three types of resin adhesives were prepared by blending 5%, 8% and 15% by weight of carbon black having a particle size of about 0.3 μm with the resin adhesive used in the production of the thin leaf. Then, a thin leaf body A was manufactured using each of them. Next, a corona discharge treatment is performed on the thin Al thin layer,
The transparent resin paint (1) used in Example 2 was applied in a thickness of 0.2 μm.

In the case of a thin sheet using a resin adhesive containing 8% by weight or more of carbon black, the brightness of the light source placed behind could not be visually recognized. Therefore, when a picture pattern was printed on the surface of the thin leaf body with a UV offset printing machine, and the picture was pasted on a window and the printed surface was observed, the printed picture was not difficult to see due to sunlight.

Example 6 Thin leaf B shown in FIG. 9 was produced as follows. On one surface of a biaxially stretched propylene film having a smooth surface without corona discharge treatment, a thickness of 25 to 30 nm is formed by a vacuum evaporation method.
To produce a laminated sheet b ₁ shown in FIG. 10 by forming the Al thin layer.

Next, a two-part curing type transparent polyurethane resin adhesive is applied to the entire surface of the Al thin layer 3 by a gravure coater so as to have a thickness of 4 to 6 μm, and the solvent is scattered by a drier. Then, the coated papers are overlapped, passed through a heated nip roller (temperature: 40 ° C.) and adhered to each other.
After leaving the resin adhesive in the air at a temperature of 40 ° C. for about 24 hours to cure the resin adhesive, the biaxially stretched polypropylene film was peeled off, the Al thin layer was transferred to coated paper, and the laminated sheet b ₂ shown in FIG. Manufactured.

On the other hand, a film (4) in which a hologram pattern was formed on one surface of a biaxially oriented polypropylene film having a smooth surface which had not been subjected to corona discharge treatment by a heating and pressing method, and a hairline pattern was also formed by a brush roller method. A film (5), a film (6) in which an embossed pattern is formed by applying a predetermined pattern pattern by a pressurized heating method, and a film (7) in which a fine unevenness is formed in forming the film to form a matte pattern, And Example 4
The film (3) used in was prepared.

[0098] Then, to produce a laminated sheet b ₃ shows the two-part curable polyurethane resin adhesive transparent to each of the film in FIG. 12 is applied to a thickness of 1~3μm by a gravure coater. Then, Al of the laminated sheet b ₂
The surface of the thin layer 3 superposed on the adhesive 6 'of the laminated sheet b _3, both stuck through the entire heating nip rollers (temperature 40 ° C.), left for a further temperature 40 ° C. for about 24 hours in the atmosphere of After curing the adhesive, the film was peeled off.

On the surface of the obtained thin leaf body, the specular metallic luster of the lower Al thin layer and the surface pattern of the upper resin layer were delicately overlapped to exhibit a unique design effect. Specifically, in the case of the thin leaf manufactured using the film (4), a hologram pattern having a metallic luster appears, and in the case of the thin leaf manufactured using the film (5), the metallic luster is reduced. In the case of a thin leaf produced using a film (6), a hairline pattern appears, and an embossed pattern having a metallic luster appears, and in the case of a thin leaf produced using the film (7), a metal sheet appears. A glossy matte pattern appeared, and in the case of the thin leaf body manufactured using the film (3), a pattern in which two types of hologram patterns having a metallic luster and a mirror-surface metallic luster were mixed appeared.

Then, the transparent resin paint (1) used in Example 2 was applied to the surface of each thin leaf with a gravure coder at a thickness of 0.1.
μm to form a resin coating film for imparting printability, and further apply a red paint, a yellow paint, a blue paint, and a transparent varnish on the UV so that they do not overlap with each other. Printing was performed with an offset printing machine. At the place where the transparent varnish is printed, the peculiar surface pattern of each thin body disappears, and the metallic glossy mirror surface is visually recognized. Was seen.

Example 7 Of the thin leaves produced in Example 6, the transparent resin paint (1) used in Example 2 was coated with a gravure coater on the entire surface of the thin leaf produced using the hologram-patterned film (3). To a thickness of 0.1 μm to form a resin coating film for imparting printability, and further apply a very thin line of characters and patterns using the same transparent resin paint (1). 0.4μm thickness
To form a two-layered resin coating film for imparting printability. Characters and designs due to very thin lines of the upper resin coating film of the two-layer structure could not be visually recognized, but these were clearly copied by a copying machine.

[0102] in the production of the laminated sheet b ₂ of Example 8 Example 6, by applying a desired pattern of adhesive to the coated paper 1 was partially transferred Al thin layer in the laminated sheet b ₁ to the coated paper side A thin sheet was produced in the same manner as in Example 6, except that the laminated sheet produced in Example 6 was used. Fig. 14 shows the obtained thin leaf.
A thin material B ₁ indicated by.

_On the surface of the thin sheet B1, on the upper surface of the Al thin layer, the surface pattern of the Al thin layer drawn in a certain pattern slightly overlaps with the surface pattern of the resin layer, and the Al thin layer is formed. The surface pattern of the resin layer was visually recognized from the portion where the pattern was not formed, and as a whole, a peculiar design effect obtained by combining these was obtained.

Example 9 Five types of films (4), (5), and
(6), (7), (3) to produce a laminated sheet b ₃ shown in FIG. 12 with, after it was superimposed on the coated paper, in the same manner as in Example 6 resin adhesive (uncured The resin was cured, and the film was peeled off to produce a thin leaf C shown in FIG. Then, the transparent resin coating (1) used in Example 2 was applied to the surface of each thin body to form a resin coating film for imparting printability.

At this time, the thickness of the coating film was 0.05 μm,
When the thickness was changed to 1 μm and 0.2 μm, the surface pattern could be recognized most reliably when the thickness was 0.05 μm. Then, when the surface was touched with a wet hand, the surface pattern of the resin layer disappeared at the place where the hand touched. On the other hand, 1% by weight of a yellow pigment was added to the transparent resin paint (1) used in Example 2 to prepare a resin paint (3).

Then, this resin paint (3) was applied to each thin body C
To form a resin coating film for imparting printability. When the surface was touched with a wet hand, the surface pattern became slightly harder to erase than the one using the transparent resin paint (1). Incidentally, to produce a laminated sheet b ₃ using a resin adhesive black carbon black is blended,
The thin leaf body C shown in FIG. 19 was manufactured using it. In the case of this thin leaf, a black three-dimensional surface pattern was visually recognized, and the surface pattern did not disappear even when the surface was touched with a wet hand.

Further, a transparent resin paint (1) and a resin paint (3) are applied respectively to form a resin paint film for imparting printability, which is formed into a film. Thin line letters and designs were applied by a cylinder using the same resin paint as the resin paint. When the base material is a double-sided coated paper, the characters and patterns are more transparent when the transparent resin paint (1) is used than when the resin paint (3) is used, even when the viewing angle is changed. It was hard to see.
