2. Description of the Related Art A hologram that reproduces a three-dimensional image by recording information of an object in the form of interference fringes, unlike conventional photographic methods, is used in many fields such as information processing, measurement, and display. There is. A photosensitive material on which such information has been recorded and developed is called a hologram, and in particular, a surface relief type hologram that records information by using the unevenness of the hologram is known. More specifically, first, a hologram image having irregularities is obtained by photographing a dry plate coated with a photoresist using an argon laser beam with the reflected light from the subject and the reference light, and developing the photographed image. A metal is vapor-deposited on the concavo-convex image to give conductivity by forming a film, nickel is plated on the vapor-deposited surface, and the plating film is peeled off to obtain a kind of mold (stamper). . Then, using this mold, a thermoplastic resin such as vinyl chloride, polystyrene, or polypropylene is heated and pressed by, for example, a flat pressure press or a roll pressure press to transfer the unevenness, and after peeling after cooling, Obtained a resin hologram (embossed hologram). Furthermore, aluminum is vacuum-deposited on the back surface of this resin hologram by about 10 nm,
A reflective hologram is created by forming a reflective layer, and a printed matter of a transparent film is laminated to make the surface image appear to be lifted from the stereoscopic screen. Further, a so-called perspective hologram is created by sandwiching a resin hologram between glass and transparent resin.

Such an embossed hologram manufacturing method is inexpensive and suitable for mass production, and is widely applied to prevent forgery of books, greeting cards, record jackets, stickers and credit cards.

Here, in the above-mentioned conventional method of manufacturing a surface relief hologram, for example, Japanese Patent Publication No. 1-5.
A hologram-forming sheet as described in 2756 is known. The hologram forming sheet described in Japanese Patent Publication No. 1-52756 has a resin layer formed by applying a urethane resin paint to a polyester sheet as a base material.
The hologram was formed on the surface of the resin layer by overlapping the resin layer and the hologram forming surface of the stamper with a press machine. Then, aluminum is deposited on the surface of the resin layer to obtain a final product.

[0005]

By the way, if an aluminum vapor deposition layer can be formed directly on the surface of a substrate and a hologram can be formed on the surface of this aluminum vapor deposition layer,
A hologram forming sheet can be manufactured.

Conventionally, as a method for forming an aluminum vapor deposition layer on the surface of a film or sheet, for example, a method of directly vapor depositing aluminum on the surface of the film, or a method of applying an undercoating agent on the surface of the film, and then A method of depositing aluminum on the surface of the formed undercoat layer is known. In particular, the former is well known as a so-called vacuum metallization method in which aluminum is vaporized in a vacuum atmosphere and condensed on the surface of a film to be deposited.

However, the above-mentioned conventional method for forming a vapor deposited aluminum layer is not suitable for depositing aluminum on the surface of a soft polyvinyl chloride film, as will be described below. First, the first method (vacuum metallization method) is carried out in a state where the film is contained in a container and the inside of the container is maintained in a high vacuum state of, for example, 10 ⁻³ to 10 ⁻⁴ Torr. Therefore, in the vacuum metallization method, the film to be vapor-deposited is limited to a material that does not release gas or a material that does not contain a component that easily evaporates. This is because when gas is generated from the film, it becomes difficult to maintain the inside of the container in a high vacuum state.

On the other hand, the soft polyvinyl chloride film contains a plasticizer such as phthalic acid ester.
Therefore, when aluminum is vapor-deposited directly on the surface of a soft polyvinyl chloride film, these plasticizers
Evaporation or decomposition causes gas to be generated, the degree of vacuum in the container does not rise sufficiently, and the evaporation efficiency of aluminum decreases. As a result, even if the vaporized aluminum was condensed on the soft polyvinyl chloride film, it was not possible to form a thin film vapor-deposited aluminum layer on the surface of which a good quality hologram was formed, and the resulting soft poly The aluminum vapor deposition layer on the vinyl chloride film has a rough surface as a whole and is inferior in specularity.

Further, even if the aluminum vapor deposition layer is directly formed on the surface of the soft polyvinyl chloride film by the vacuum vapor deposition method, the plasticizer diffuses on the surface of the soft polyvinyl chloride film, so that the aluminum vapor deposition layer is formed over time. The adhesive force between the soft polyvinyl chloride film and the soft polyvinyl chloride film is weakened, and the aluminum vapor deposition layer may be peeled off from the soft polyvinyl chloride film when printing is performed on the surface of the aluminum vapor deposition layer.

On the other hand, in the second method, it is necessary to apply the undercoat agent to the surface of the film and then dry the solvent of the undercoat agent. Usually, drying the solvent
This is done by heating the film. The heat at this time may cause the flexible polyvinyl chloride film to stretch in the longitudinal direction and to shrink in the width direction. For this reason, the widthwise dimension of the soft polyvinyl chloride film and the thickness of the film change. Therefore, irregularities are generated in the wound product of the soft polyvinyl chloride film after drying, which makes the vapor deposition work difficult.

Further, in the second method, the solvent of the undercoat agent causes the soft polyvinyl chloride film to become swelled, and it is difficult to form a uniform thin film aluminum vapor deposition layer.

The present invention has been made in view of the above points. Firstly, a soft polyvinyl chloride laminate on which a thin film hologram is formed that is uniform and has excellent smoothness and also has excellent adhesion. And a method for manufacturing the same.

Secondly, the present invention provides a soft polyvinyl chloride laminate having a hologram, on which a hologram is formed, which facilitates printing on the surface of a thin metal vapor deposition layer, and a method for producing the same. The purpose is to

Thirdly, the present invention provides a soft polyvinyl chloride in which a hologram is formed which has good adhesion between the adhesive layer and the soft polyvinyl chloride layer, is not deteriorated by a solvent, and is free from expansion and contraction and fuzzy. An object is to provide a laminate and a method for manufacturing the same.

Fourthly, the present invention provides a hologram which prevents the plasticizer from scattering from the soft polyvinyl chloride layer and is resistant to discoloration and deterioration of the metal vapor deposition layer and the adhesive layer due to sunlight, temperature, humidity and the like. It is an object to provide a formed soft polyvinyl chloride laminate and a method for producing the same.

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing a soft polyvinyl chloride laminate on which the hologram of the first mode is formed. As shown in FIG. 1, the soft polyvinyl chloride laminate 10 of the first embodiment has a soft polyvinyl chloride layer 11,
The adhesive layer 12, the aluminum vapor deposition layer 13, and the overcoat layer 14 are sequentially laminated.

The first soft polyvinyl chloride layer 11 is made of soft polyvinyl chloride. The soft polyvinyl chloride used in the present invention is a so-called external plasticized soft polyvinyl chloride obtained by plasticizing a vinyl chloride polymer by adding a plasticizer. The plasticizer contained here is, for example, a phthalate ester.

The soft polyvinyl chloride layer 11 includes any film, sheet and web made of soft polyvinyl chloride. The thickness of the soft polyvinyl chloride layer 11 is not particularly limited, but is, for example, 20 to 400 μm.

Adhesive layer 1 of soft polyvinyl chloride layer 11
The surface on which 2 is formed can be subjected to corona discharge treatment in advance to roughen the surface. As a result, the adhesive layer 12 and the soft polyvinyl chloride layer 11 can be bonded very firmly.

The second adhesive layer 12 is preferably a two-component curing type adhesive or a photo-curing type adhesive used for dry lamination. The two-component curable adhesive is an adhesive that cures over time, and is cured in a shorter time when heated. For example, a urethane resin adhesive or an epoxy resin adhesive is used. The photo-curable adhesive is a type that is cured by irradiation with electron beams or ultraviolet rays, and is, for example, a urethane resin adhesive or an acrylic adhesive. More specifically, a two-component curing type polyurethane resin adhesive is dried at 4 to 4 m2 / m2.
Apply 8 g and cure at 40 ° C. for 24 hours.

The third aluminum vapor deposition layer 13 is a thin film formed by evaporating aluminum and then condensing it on the surface of the adherend. The thickness of the aluminum vapor deposition layer 13 is preferably thinner than the wavelength of light, for example, 1000 Å (A) or less. Considering the light-shielding property, the moisture-proof property, and the gas barrier property, the range of 50 to 700 A is preferable. Further, when considering the saving of the aluminum material, the range of 200 to 250 A is particularly preferable.

A hologram 13a is formed on the surface of the aluminum vapor deposition layer 13. The hologram 13a is
This is a so-called surface relief hologram, which is composed of irregularities formed on the surface of the aluminum vapor deposition layer 13.

The fourth overcoat layer 14 is provided for the under lacquer which improves the compatibility with the printing ink when the printing ink layer is formed on the uppermost layer. Therefore, when using a special ink for vinyl processing, which has excellent compatibility with the aluminum vapor deposition layer 13, as the printing ink, the overcoat layer 14 can be omitted.

The overcoat layer 14 is usually formed by applying an under lacquer material dissolved in a low boiling point solvent such as ethyl acetate on the surface of the aluminum vapor-deposited layer 13 and then drying at low temperature at 40 to 80 ° C. Is formed by.

The overcoat layer 14 is specifically made of a general under lacquer material which imparts printability. The printing ink layer 15 can be formed on the surface of the overcoat layer 14 as described above. The printing ink layer 15 is
It can be formed by an ordinary printing method. Examples include offset printing, UV offset printing, gravure printing, silk screen printing or flexo printing.

The adhesive layer 12, the aluminum vapor deposition layer 13 and the overcoat layer 14 may be provided on the entire surface of the soft polyvinyl chloride layer 11 as shown in FIG. Further, it can be provided on the surface of the polyvinyl chloride layer 11 only partially in accordance with a desired design or pattern.

In the soft polyvinyl chloride laminate 10 of the first embodiment described above, the adhesive layer 12 is provided on the surface of the soft polyvinyl chloride layer 11. Therefore, the plasticizer contained in the soft polyvinyl chloride layer 11 is prevented from diffusing at the interface between the soft polyvinyl chloride layer 11 and the adhesive layer 12. Therefore, it is possible to prevent the adhesive force between the soft polyvinyl chloride layer 11 and the aluminum vapor deposition layer 13 laminated on the upper side of the adhesive layer 12 from weakening with the passage of time.
Moreover, since the adhesive layer 12 adheres the soft polyvinyl chloride layer 11 and the aluminum vapor deposition layer 13, the two adhere more firmly than when the aluminum is directly vapor-deposited on the surface of the soft polyvinyl chloride layer 11. Has been done. As a result, for example, when the surface of the overcoat layer 14 is printed, the aluminum vapor deposition layer 13 can be prevented from peeling from the soft polyvinyl chloride layer 11.

Further, since the adhesive layer 12 absorbs the aluminum particles of the aluminum vapor deposition layer 13, it is possible to prevent the oxidation of aluminum. In addition, the adhesive layer 12
Can smooth the surface of the soft polyvinyl chloride layer 11 roughened by the corona discharge treatment.

Further, in the adhesive layer 12, the plasticizer contained in the soft polyvinyl chloride layer 11 is the soft polyvinyl chloride layer 1.
1 to prevent scattering to the outside. Therefore, the flexibility of the soft polyvinyl chloride layer 11 can be maintained for a long time.

Further, an overcoat layer 14 is provided on the surface of the aluminum vapor deposition layer 13. Since the overcoat layer 14 is well compatible with printing ink, various types of printing can be easily performed on the surface of the overcoat layer 14. In addition, the overcoat layer 14 is formed of the aluminum vapor deposition layer 13 and the adhesive layer 1 from the sunlight, temperature or humidity.
2 can be protected and discoloration or deterioration of these layers can be prevented.

Inside the lower chamber 32, a sufficient number of reservoirs 33 storing aluminum 34 are provided to form a uniform and uniform aluminum vapor deposition layer 13 on the transfer material 21. For example, for the transfer material 21 having a width of 75 cm, 10 storages 33 having a width of 3 cm and a length of 15 cm are provided. Each reservoir 33 is heated to the liquefaction temperature of aluminum 34, for example, 1500 ° C. On the other hand, the transfer material 21 guided to the lower chamber 32 is kept at room temperature by the water cooling drum 35.

The aluminum particles 36 heated and vaporized in the reservoir 33 move toward the transfer material 21 on the water cooling drum 34 due to the temperature difference between the reservoir 33 and the water cooling drum 35, and the surface of the transfer material 21. Condense on top. As a result, as shown in FIG. 2, a transfer material 21 (hereinafter, referred to as a first stacked body 20) having the aluminum vapor deposition layer 13 deposited thereon is obtained. The first stacked body 20 is guided to the winding portion 37 by the guide roller 31 and wound up in a roll shape.

Further, the speed of the transfer material 21 passing through the lower chamber 32 and the temperature of the storage device 33 are adjusted according to the thickness of the aluminum vapor deposition layer 13 vapor-deposited on the transfer material 21.

Next, after the adhesive layer 12 is provided on the surface of the aluminum vapor deposition layer 13 of the first laminate 20, the adhesive layer 1 is formed.
The soft polyvinyl chloride layer 11 is adhered to the surface of 2. FIG.
FIG. 3 is a cross-sectional view showing a state in which an adhesive layer is provided on the surface of aluminum vapor deposition layer 13. FIG. 5 is a cross-sectional view showing a state where the adhesive layer 12 and the soft polyvinyl chloride layer 11 are in contact with each other. FIG. 6 shows the adhesive layer 1 on the surface of the aluminum vapor deposition layer 13.
2 is a diagram schematically showing a step of providing 2 and bonding the adhesive layer 12 and the soft polyvinyl chloride layer 11 together.

First, as shown in FIG. 6, a web-shaped soft polyvinyl chloride film 41, which is a soft polyvinyl chloride layer, is pulled out from a roll 61, and is guided by a guide roller 62.
And is passed through the inside of the corona discharger 63. In the corona discharger 63, one surface of the soft polyvinyl chloride film 41 is subjected to corona discharge treatment and roughened.

On the other hand, the adhesive layer 12 is formed on the surface of the aluminum vapor deposition layer 13 of the first laminate 20. Specifically, the first laminated body 20 is pulled out from the roll 59, guided by a guide roller 64, and guided to a pair of rollers 65 and 66 arranged so as to face each other so as to sandwich the first laminated body 20. One roller 66 of the pair of rollers 65, 66
Is immersed in the adhesive solution 68 contained in the adhesive tank 67. The roller 66 also rotates according to the movement of the first stacked body 20. As a result, the adhesive solution 68 is applied onto the surface of the aluminum vapor deposition layer 13. Then, in the drying unit 69, 5
Hot air of 0 to 80 ° C is blown. As a result, the solvent is evaporated and removed from the adhesive solution 69, and a uniform adhesive layer 12 is formed on the surface of the aluminum vapor deposition layer 13 as shown in FIG.

Adhesive layer 12 and aluminum vapor deposition layer 1
The transfer material 21 in which 3 is laminated (hereinafter referred to as the second laminated body 40) is composed of the soft polyvinyl chloride film 41 and the adhesive layer 12 and the soft polyvinyl chloride film 41 before the adhesive layer 12 is cured. It is sandwiched by a pair of rollers 70 and 71 so that the surfaces subjected to corona discharge treatment come into contact with each other. One roller 70 is, for example, a rubber roller having a Shore hardness of about 75, and the other roller 71 is made of chrome or made of stainless steel. A predetermined pressure is applied between the pair of rollers 70 and 71. A pair of rollers 70, 7
The pressure between 1 is set in inverse proportion to the diameter of the rollers 70 and 71. For example, when the diameter of the roller 71 is about 50 cm, it is set within the range of 5 to 6 kg.

The second laminate 40 and the soft polyvinyl chloride film 41 are integrated between the pair of rollers 70 and 71. Then, the integrated second laminated body 40 and the soft polyvinyl chloride film 41 are wound by the winding roller 72.

Then, the integrated second laminated body 40 and soft polyvinyl chloride film 41 are stored in an environment of 40 to 60 ° C. for 24 to 72 hours, whereby the adhesive layer 12 is cured. As a result, as shown in FIG. 5, the third laminated body 50 in which the soft polyvinyl chloride film 41 is adhered to the surface of the adhesive layer 12 of the second laminated body 40 is obtained. When a photo-curable adhesive is used for the adhesive layer 12, the adhesive layer 12 is cured by an ultraviolet irradiation device or an electron beam irradiation device and does not need to be stored for a long time.

Next, the transfer material 21 is peeled off from the third laminated body 50. FIG. 7 is a diagram schematically showing a step of peeling the transfer material 21 from the third stacked body 50. Third stacked body 5
0 is drawn out from the winding roller 72 and introduced between the pair of rolls 81 and 82. Here, the third stacked body 50
Then, the transfer material 21 is peeled off. The transfer material 21 is a roll 9
It is wound up by 1. On the other hand, the soft polyvinyl chloride film 41, the adhesive layer 2 and the aluminum vapor deposition layer 14
The laminated body 83 is rolled up by a roll 84. As a result, a fourth laminated body in which the aluminum vapor deposition layer 13 is provided on the surface of the soft polyvinyl chloride film 41 with the adhesive 12 interposed therebetween is obtained. Obtained aluminum vapor deposition layer 1
On the surface of No. 3, a hologram 13a corresponding to the unevenness formed on the surface of the transfer material 21 is formed.

Next, the aluminum vapor deposition layer 1 of the fourth laminated body
The overcoat layer 14 is formed on the surface of No. 3. First,
The surface of the aluminum vapor deposition layer 13 is subjected to corona discharge treatment by a corona discharger and roughened. Then, an under lacquer material dissolved in a low boiling point solvent is applied to the surface of the roughened aluminum vapor deposition layer 4 and dried at a low temperature. As a result, the soft polyvinyl chloride laminate 10 is obtained.

The soft polyvinyl chloride laminate 10 is subjected to a usual printing process on the surface of the overcoat layer 14. When the aluminum vapor deposition layer 13 is partially provided on the surface of the soft polyvinyl chloride film 41, in the step of forming the adhesive layer 12 on the surface of the aluminum vapor deposition layer 13 described above, the adhesive layer 12 is replaced with the aluminum vapor deposition layer. It is not formed on the entire surface of 13, but is applied only on a part of the surface of the aluminum vapor deposition layer 13 in accordance with a desired design and pattern.
In this case, in the step of peeling the transfer material 21 from the third stacked body 50, only the aluminum vapor deposition layer 12 in the portion where the adhesive layer 12 is formed is transferred to the surface of the corresponding soft polyvinyl chloride film 41 and bonded. The aluminum vapor deposition layer 12 in the portion where the agent layer 12 is not formed is left as it is on the transfer material 21.

In the method of manufacturing the soft polyvinyl chloride laminate 10 of the first embodiment described above, the aluminum vapor deposition layer 13 is formed on the surface of the transfer material 21 by the vacuum vapor deposition method.
Then, the adhesive layer 12 is formed on the surface of the aluminum vapor deposition layer 13.
Are formed and transferred to the soft polyvinyl chloride film 41. For this reason, the soft polyvinyl chloride film 41 itself is not exposed to the vacuum vapor deposition process, and therefore, there is no problem even if it contains a plasticizer that evaporates or decomposes by the vacuum vapor deposition process to generate gas. On the other hand, as the transfer material 21, a material suitable for the vacuum deposition method can be appropriately selected and used. That is, a material that does not generate gas can be used in the step of vacuum-depositing aluminum. Further, the transfer material 21 after peeling can be reused, which is economical. Transfer material 21
When a biaxially stretched polypropylene film is used as, the aluminum vapor deposition layer 13 is easily peeled off, which is suitable for reusing the transfer material 21.

Further, unevenness 21a is formed on the surface of the transfer material 21, aluminum is vapor-deposited on the surface on which the unevenness 21a is formed, and then transferred to the surface of the soft polyvinyl chloride film 41. As a result, the hologram 13a corresponding to the unevenness 21a formed on the surface of the transfer material 21 is formed on the surface of the transferred aluminum vapor deposition layer 13.

Further, according to the method for manufacturing the soft polyvinyl chloride laminate 10 of the above-mentioned first embodiment, the above-mentioned conventional second
There is no need to provide an undercoat layer on the surface of the soft polyvinyl chloride film 41 as in the method of (1). Therefore, there is no possibility that the soft polyvinyl chloride film 41 deteriorates, expands, contracts, or swells due to the heat for forming the undercoat layer. As a result, it is possible to easily manufacture the soft polyvinyl chloride laminate 10 having the thin film-shaped aluminum vapor deposition layer 13 on which a uniform and good hologram is formed.

Further, by using a material whose surface is not treated as the transfer material 21 and not providing a peeling layer, it is possible to prevent aluminum particles from being excessively deposited on the surface of the transfer material 21, and it is extremely thin. Aluminum vapor deposition layer 1
3, specifically 50 to 700 A, preferably 200 to 7
The aluminum vapor deposition layer 13 of 00A can be formed. As a result, the soft polyvinyl chloride laminate 10 having excellent light-shielding properties, moisture-proof properties, and gas barrier properties can be manufactured using a small amount of aluminum material.

In the method for manufacturing the soft polyvinyl chloride laminate 10 of the first embodiment described above, the overcoat layer 14
Is applied to the surface of the aluminum vapor deposition layer 13 and then dried at a low temperature. Therefore, the soft polyvinyl chloride film 4
1 is not heated at a high temperature, and there is no possibility that the soft polyvinyl chloride film 41 deteriorates, expands, contracts, or swells due to heat.
As a result, it is possible to easily manufacture the soft polyvinyl chloride laminate 10 having the thin film vapor-deposited aluminum layer 13 on which a smooth and excellent hologram is formed.

Next, the soft polyvinyl chloride laminate of the second embodiment of the present invention will be described. FIG. 8 is a cross-sectional view of a soft polyvinyl chloride film having an aluminum vapor deposition layer transferred thereto according to the second embodiment of the present invention. The same reference numerals as those of the first embodiment indicate the same members.

As shown in FIG. 8, the soft polyvinyl chloride laminate 100 of this embodiment comprises a protective sheet 101, a re-adhesive material layer 102, a soft polyvinyl chloride layer 11, an adhesive layer 12,
The aluminum vapor deposition layer 13 and the overcoat layer 14 are sequentially laminated.

Here, the protective sheet 101 is provided, for example, to protect the re-adhesive material layer 102, which is made of a material obtained by subjecting a high-quality kraft paper to polyethylene extrusion lamination and having a surface siliconized.

The re-adhesive layer 102 is provided on one surface of the soft polyvinyl chloride layer 11 opposite to the adhesive layer 12. The re-adhesive layer 102 is made of an adhesive that can be repeatedly peeled and adhered. For example, an acrylic acid ester-based resin can be used.

A product in which a re-adhesive layer 102 and a protective sheet 101 are sequentially provided on one surface of a soft polyvinyl chloride film is usually commercially available under the name of "adhesive paper".

Next, in the production of the soft polyvinyl chloride laminate 100 of the second embodiment described above, instead of the soft polyvinyl chloride film 41 shown in FIG. 6, the protective sheet 10 is provided on one side.
The same operation can be performed except that a soft polyvinyl chloride film in which No. 1 and the re-adhesive layer 102 are laminated is used.
