Disclosure of the Invention

Problems to be Solved by the Invention

However, since the nameplate manufacturing laminated body of the structure disclosed by the said patent document 1 must be manufactured by the single-sheet type which vapor-deposits a metal sheet with respect to one sheet of transparent sheet when forming a metal vapor deposition film, it is continuous on a series of manufacturing lines. It was difficult to produce the product, the production efficiency was poor, and when the sheet was widened, the warpage occurred, the productivity was lowered, and the number of processes was increased. .

On the other hand, as disclosed in Patent Literature 2, a metal deposition layer is formed on one side of a PET film, for example, using a metal transfer foil, a metal gloss film, or the like, while laminating the injection resin on the opposite side via an adhesive layer. In the constitution, fine irregularities are generated at the interface between the adhesive layer and the PET film or at the interface between the adhesive layer and the transparent resin during transfer or injection molding of the metal transfer foil, and distortion (also referred to as "shaking") is generated in the reflected light. . For example, looking at the reflection image on a fluorescent lamp, there was a problem that a myriad of aroma marks such as tangerine peel appeared on the surface of the laminate.

In addition, when the metal transfer foil is used, unevenness (coating nonuniformity) occurs at the interface between the corrosion preventing layer and the metal layer or at the interface between the metal layer and the adhesive layer during coating of the transfer foil. There was a problem that deformation occurred.

As described above, the in-mold injection molded article using the metal gloss film or the metal transfer foil can be produced at a relatively low cost, but has a problem that the designability is inferior to that of metal deposition directly on a transparent substrate.

Therefore, the present invention can produce a name plate manufacturing laminate having a deep metallic appearance and can be easily and largely yielded with high yield, and more preferably, there is no occurrence of distortion (shaking) due to the reflected light. When looking at the reflection image of the fluorescent lamp, it is to provide a laminate for making a new nameplate that does not show any mandarin marks such as tangerine peel.

Means to solve the problem

The present invention is a metal luster having a laminated structure formed by laminating the pressure-sensitive adhesive layer (2) and the metal vapor deposition film (3) sequentially from the viewing side (also referred to as the "surface side") on the back surface side of the transparent substrate (1). As a laminated body for nameplate manufacture provided, the metal vapor deposition film 3 laminate | stacks the metal vapor deposition layer 5 on the single side | surface side of the transparent resin film 4 (it contains the modified PET film 4A. Hereinafter, the same), The laminated body for manufacture of the nameplate with metal luster which consists of what consists of the thing which prescribed | regulated the thickness of this transparent resin film 4 to 150 micrometers-300 micrometers is proposed.

The laminated body for nameplate manufacture of this invention provided with the said structure is equipped with the metal vapor deposition film 3 in the back surface side of the transparent substrate 1 which consists of synthetic resins, and the refraction of the light by the thickness of the transparent substrate 1 is carried out. By the glossiness by the metal vapor deposition film 3, the external appearance can be seen in a deep metallic tone.

The metal vapor deposition film 3 may be formed by forming the metal vapor deposition layer 5 on either the surface side or the rear surface side of the transparent resin film 4, but the metal may be formed on the surface side of the transparent resin film 4. It is preferable to form the vapor deposition layer 5. Thus, when the metal vapor deposition layer 5 is formed in the surface side of the transparent resin film 4, the transparent resin film 4 which forms the base material of the metal vapor deposition film 3, and is located in the back surface of the metal vapor deposition layer 5 is carried out. By specifying the thickness of), distortion (shaking) caused by the reflected light can be eliminated, and in particular, when the reflection image of the fluorescent lamp is viewed, it is possible to prevent a mark like a tangerine peel. When this point is explained in detail, generally, when laminating a polyethylene terephthalate film (hereinafter referred to as "PET") film and an adhesive layer on a metallic gloss film, it is often used for transparent film substrates having a thickness of 50 µm to 100 µm (Example For example, see Japanese Unexamined Patent Publication No. 2004-50778 paragraph). In this case, distortion occurs in the reflected light, and the reflection image of the fluorescent lamp on the surface shows that numerous abrasions such as tangerine peel occur on the surface. There was a problem. Therefore, as a result of the inventors finding this cause, the curvature of the uneven | corrugated irregularities in the interface of a film and an adhesion layer causes it to thicken a base film, specifically 150 micrometers or more, Preferably it thickens to 175 micrometers or more, I found out that it can eliminate the curvature of countless irregularities.

Moreover, in the general metal vapor deposition film 3, in order to prevent the corrosion of a metal vapor deposition part, a top coat layer is often formed, but when the top coat layer feels bad, it will worsen the appearance of a laminated body as it is. do. Therefore, by forming the metal vapor deposition layer 5 on the surface side of the transparent resin film 4, ie, the side which contacts the adhesion layer 2, without exposing the metal vapor deposition layer 5 (a topcoat layer is needed). The corrosion of the metal vapor deposition layer 5 can be prevented.

In the case where the transparent substrate 1 is made of a synthetic resin, the metal vapor deposition film 3 has a configuration in which the metal vapor deposition layer 5 is laminated on one side of the modified PET film 4A, and the modification is performed. PET film 4A has an average linear expansion coefficient at 30 ° C. to 60 ° C., and the difference with the transparent substrate 1 is within 3 × 10 ⁻⁵ / ° C., and the thickness thereof is 150 μm to 300 μm. It is especially preferable to use.

In the case where the transparent substrate 1 is made of a synthetic resin, warping under a high temperature environment becomes a problem, but as the base film forming the substrate of the metal vapor deposition film 3, the average linear expansion coefficient at 30 ° C. to 60 ° C., By using the modified PET film 4A whose difference is less than 3x10 <^-5> / ^degreeC compared with the transparent substrate 1, curvature in high temperature environment can be prevented.

In the laminated body for nameplate manufacture provided with the said structure, black printing is given to the whole surface or one part of the back surface of the metal vapor deposition film 3, for example, and it has a structure which makes the part which performed the said black printing a mirror surface part. It can be set as a laminated body for nameplate manufacture.

Moreover, coloring metal gloss can also be provided to the laminated body for nameplate manufacture by adding a coloring agent to the adhesion layer 2, and including a coloring agent in the adhesion layer 2. Thus, only by adding a coloring agent (pigment, dye, etc.) to the adhesion layer 2, since colored metal luster can be given to the laminated body for nameplate manufacture, it is simple and yields in large quantities, and is more excellent in designability. The laminated body for nameplate manufacture can be produced. At this time, if the thickness of the colored adhesion layer 2 is constant, even if the thickness of the transparent substrate 1 is changed, since a hue does not change, the depth of an external appearance can be changed freely without falling productivity.

When this point is explained in detail, when it is going to colorize the laminated body for metal plate manufacture provided with the metallic luster, it was conventionally to add a coloring agent to the transparent substrate 1, but it was a transparent substrate (extrusion method and cast In the case of adding a colorant and producing a small amount by the manufacturing process of the method or the like, the number of steps increases and the manufacturing cost increases, and when the colorant is added and colored to the transparent substrate 1, the color tone changes due to a subtle thickness difference. In addition, the control of thickness is very difficult.

On the other hand, in the structure of the laminated body for nameplate manufacture of this invention, when it is made to include in the coloring agent in the adhesion layer 2 located in the back surface side of the transparent substrate 1, even if the thickness of the transparent substrate 1 changes, a color tone In addition, it can express colors with a sense of transparency such as light water color and pink. In addition, when the transparent substrate is obliquely transmitted through the cross section of the transparent substrate, a new design effect of greatly changing the color tone depending on the viewing angle can be obtained, and the design of the name plate can be dramatically increased.

Furthermore, it can also be set as the laminated body for nameplate manufacture which has a laminated structure formed by laminating | stacking the hard-coat film 7 on the surface side of the transparent substrate 1 via the adhesion layer 6.

The laminated body for manufacture of the nameplate of the present invention is, for example, on one side of the transparent substrate 1 in an extension line of a production line that continuously forms the transparent substrate 1 by an extrusion method or a continuous cast method. Since the metal vapor deposition film 3 can be continuously manufactured by attaching the metal vapor deposition film 3 through the adhesion roller via the adhesion layer 2, since it can produce efficiently, the widening of the sheet body is easy, and the number of processes is few, It is easy to manage etc., and also has the characteristic that a yield is also good.

In addition, said extrusion method or continuous casting method includes the method generally considered as extrusion method or continuous casting method widely, and can use them freely in this invention.

Moreover, the adhesion layer 2 and the metal vapor deposition film 3 are laminated | stacked, and the said metal vapor deposition film 3 forms the metal vapor deposition layer 5 in the single side | surface side of the transparent resin film 4 as And the pressure-sensitive adhesive metal vapor deposition film having a constitution in which the thickness of the transparent resin film 4 is defined to be 150 μm to 300 μm are produced, and the adhesive layer 2 is attached to the transparent substrate 1 via the adhesive layer 2. The said laminated body for nameplate manufacture can be manufactured.

Therefore, this invention is made by laminating | stacking the adhesion layer 2 and the metal vapor deposition film 3 as a metal vapor deposition film with an adhesive for forming the said laminated body for nameplate manufacture, The said metal vapor deposition film 3 is a transparent resin. The metal vapor deposition layer 5 which forms the metal vapor deposition layer 5 in the single side | surface side of the film 4, and also about the metal vapor deposition film with an adhesive provided with the structure which defines the thickness of this transparent resin film 4 to 150 micrometers-300 micrometers I would suggest.

Moreover, it can be set as having the colored metal gloss by containing a coloring agent in the adhesion layer 2 in the said metal vapor deposition film with an adhesive.

It is. Although it does not specifically specify the content rate of the said main component, The component (when two or more components are a main component, these total amounts) is 50 mass% or more in this composition, Preferably it is 70 mass% or more, Especially preferably, 90 mass It is common to make up more than% (including 100%).

In addition, in this specification, when it describes as "X-Y" (X and Y are arbitrary numbers), it means "X or more and Y or less", unless it notices specially, "It is larger than X preferably Y, Less than. ”

[First embodiment]

As 1st Embodiment, as shown in FIG. 1, the adhesion layer 2 and a metal are in the back surface side of the transparent substrate 1 (the back surface side seen from the viewing side, ie, the opposite side to the surface side which is the viewing side). The laminated body (A) for nameplate manufacture which has a laminated structure formed by laminating | stacking the vapor deposition film 3 one by one is demonstrated.

(Transparent substrate (1))

If the transparent substrate 1 is transparent and a flat plate, the shape and material will not be specifically limited, It is preferable that it is comprised from the transparent resin which can aim at light weight to thin thickness. Specifically, polymethyl methacrylate (PMMA) resin, polycarbonate (PC) resin, methyl methacrylate-styrene copolymer resin (MS resin), polyarylate resin, polysulfone resin, polyether sulfone resin It is preferable that it is a transparent substrate which has at least 1 sort (s) as a main component from the group which consists of norbornene-type resin, cycloolefin (alicyclic) resin, and glass.

As a constituent of the transparent substrate 1, conventionally known additives, for example, antioxidants such as phenol and phosphorus, halogen-based and phosphorus-based flame retardants, heat-resistant aging agents, ultraviolet absorbers, lubricants, antistatic agents and the like may be blended. .

The transparent substrate 1 may be a plate body made of a single layer or may be a plate body of a multilayer structure made of two or more layers. For example, as the transparent substrate 1, a transparent substrate in which a hard coat layer is laminated on one side or both sides of a substrate made of a transparent resin may be used. Under the present circumstances, as a hard-coat layer, what is formed by apply | coating and forming the composition containing an ultraviolet curing polyfunctional (meth) acrylate, a ultraviolet absorber, a photocuring initiator, colloidal silica, an inorganic or organic filler, etc. is mentioned, for example. have. However, it is not limited to this.

It is preferable to set the thickness of the transparent substrate 1 suitably in the range of 0.5 mm-10 mm. The laminated body A for this nameplate manufacture forms the metal vapor deposition film 3 in the back surface side of the transparent substrate 1, and the refraction of the light by the thickness of the transparent substrate 1 and the metal vapor deposition film 3 Although the appearance can be seen as a deep metallic tone by the glossiness, the thicker the thickness of the transparent substrate is, the higher the thickness can be. From this viewpoint, the thickness of the transparent substrate 1 is preferably 2 mm to 7 mm, particularly 2 mm to 5 mm.

Moreover, it is also preferable to consider a processing method for the thickness of the transparent substrate 1, For example, when punching, it is the range of 0.5 mm-1.5 mm from a viewpoint of obtaining the thing with little whitening of a cross section and a favorable appearance. It is preferable to set to.

It is preferable that the transparency of the transparent substrate 1 is 85% or more in total light transmittance by JISK-7105, and is less than 1% of haze.

(Adhesive layer (2))

UV cure type and thermosetting adhesive which are generally used can be used for the adhesion layer 2 interposed between the transparent substrate 1 and the metal vapor deposition film 3, and 180 degrees C of viscoelasticity is 1x10 <^5> It is preferable to use the adhesive which is VIII-1 * 10 <^6> Pa, especially 2 * 10 <^5> Pay- ⁵ * 10 <^5> Pa.

If the pressure-sensitive adhesive satisfies this range, since the pressure-sensitive adhesive layer 2 has elasticity that exceeds the foaming force of the outgas with respect to the outgas generated in the transparent substrate 1 in a high temperature / humidity environment, the transparent substrate ( Foaming, peeling, lifting, etc. at the interface of 1) and the adhesion layer 2 or the interface of the metal vapor deposition film 3 and the adhesion layer 2 can be suppressed. Moreover, when it adheres with an adhesive, it is generally necessary to carry out autoclave processing in order to maintain wettability, but if it is an adhesive which satisfy | fills the said range, it is not necessary to autoclave-process and high temperature, high humidity test (for example, 95 degreeC 95%) RH, and 168 hours of standing) can increase the durability.

As a composition of an adhesive, it is a (meth) acrylic-ester type copolymer which has an alkyl (meth) acrylate, a functional group containing monomer, and a (meth) acryloyl group as a main component, for example, The molecular weight of a copolymer is 500,000-200 It is preferable that it is about 10,000. Examples of such a (meth) acrylic acid ester copolymer include those obtained by copolymerizing 2-ethylhexyl acrylate, n-butyl acrylate, acrylic acid, and other monomers (macromonomer or vinyl monomer).

Moreover, in order to adjust the cohesion force and viscoelasticity of an adhesive, it is preferable to add the polyfunctional compound which can form a crosslinked structure between the said (meth) acrylic-ester type copolymers as a crosslinking agent.

As a crosslinking agent which can be used at this time, an isocyanate type compound, an epoxy type compound, an amine type compound, a metal chelate type compound, and an aziridine type compound are mentioned, As said epoxy type compound, bisphenol A, ethylene glycol glycidyl ether, glycerin Diglycidyl ether and the like. Examples of the amine compound include hexamethylenediamine and triethyldiamine. Examples of the metal chelate compound include aluminum, iron, copper, zinc, tin, titanium, nickel, antimony, The compound which polyvalent metals, such as magnesium, vanadium, and chromium coordinated to acetylacetone and ethyl acetoacetate, etc. are mentioned, As an aziridine type compound, triethylene melamine etc. are mentioned.

Such crosslinking agent may mix | blend one or more types 0.001-0.1 mass part normally with respect to 100 mass parts of main components (for example, acrylic resin component), and can adjust the viscoelasticity of an adhesive to the said range by adjusting the kind and addition amount of a crosslinking agent. have.

In addition, you may mix | blend components, such as a well-known additive, for example, a tackifier, a plasticizer, a softener, a dye, and a silane coupling agent.

A commercial item can also be used as an adhesive which satisfy | fills said conditions. For example, Soken Chemical Co., Ltd. make: Product name SK Dyne 1882 (180 ° C viscoelasticity: 3.1 × 10 ⁵ kPa), Soken Chemical Co., Ltd. make: Product name SK dyne 1888 (180 ° C viscoelasticity: 2.5 × 10 ⁵ kPa) Etc. can be used.

Moreover, by adding a coloring agent to the adhesion layer 2, a metallic luster can be colored by a desired color, a coloring metal luster can be provided to the laminated body (A) for nameplate manufacture, and the nameplate produced in the future, and the designability of a nameplate Can be dramatically improved.

What is necessary is just to add coloring agents, such as an organic pigment and dye, as a coloring agent mix | blended with the adhesion layer 2. Among them, organic pigments are preferred from the viewpoint of weather resistance and heat resistance.

Examples of the organic pigment include carbon black as a black pigment, a phthalocyanine pigment as a blue pigment, an indanthrene blue pigment, a quinacridone pigment as a red pigment, a watching pigment, a permanent pigment, an anthraquinone pigment, and the like. In addition, any 1 or 2 or more types of these can be combined suitably, and in that case, color can be adjusted with the compounding ratio of a pigment.

It is preferable that the thickness of the adhesion layer 2 shall be 10 micrometers-30 micrometers. In order to obtain adhesive force, it is more preferable that it is 15 micrometers or more. On the other hand, when it exceeds 30 micrometers, there exists a possibility that the adhesive surface may be ruined at the time of adhesive coating, and may worsen an external appearance. From this viewpoint, the thickness of the pressure-sensitive adhesive layer 2 is more preferably 15 µm to 25 µm.

In addition, the pressure-sensitive adhesive layer 2 formed on the transparent substrate 1 can alleviate the impact stress at the time of punching processing, and when the normal acrylic plate is punched, whitening occurs in the cross section, but this problem is reduced. It also plays a role.

(Metal Deposition Film (3))

The metal vapor deposition film 3 forms the metal vapor deposition layer 5 in the surface side (it is also called the viewing side or the adhesion layer 2 side) of the transparent resin film 4, and of the said transparent resin film 4 The thickness is regulated in a predetermined range.

In this type of general metal deposition film, since the metal deposition layer is easily corroded under the influence of oxygen or moisture in the air, it is common to form a corrosion prevention layer (top coat layer). By the way, when this corrosion prevention layer is formed by general coating methods, such as a die-coating method, a subtle distortion will generate | occur | produce on a film surface and it will become a factor which worsens an external appearance when seeing reflected light. In particular, if the topcoat layer has a bad cotton texture, it leads directly to deterioration of the overall appearance of the laminate. Therefore, in this embodiment, the metal vapor deposition layer 5 is formed without exposing the metal vapor deposition layer 5 by forming the metal vapor deposition layer 5 on the surface side of the transparent resin film 4, ie, the adhesion layer 2 side. Corrosion was prevented and the top coat layer was not required to be formed.

It is preferable that the metal vapor deposition film 3 is a film provided with the metallic luster by which the total light transmittance by JIS K-7105 will be 50% or less.

Here, in order to prepare the total light transmittance of the metal vapor deposition film 3 to 50% or less, it can implement by adjusting the metal density | concentration in the metal vapor deposition layer 5, and the line speed at the time of manufacture, for example.

The transparent resin film 4 as a film base material of the metal vapor deposition film 3 is a main component of PET film and cellulose triacetate (also called "TAC") which have polyethylene terephthalate (also called "PET") as a main component, for example. Preferred examples include a TAC film, a film containing polycarbonate as a main component, and the like. Moreover, it is preferable to use the biaxially stretched film which is excellent in an optical characteristic for the transparent resin film 4.

As a means of forming the metal vapor deposition layer 5 in the transparent resin film 4, the method of vacuum-depositing metals, such as aluminum, chromium, and nickel, the method of sputtering the said metal, etc. are mentioned. However, it is not limited to these methods.

In order to raise the adhesive force with a film, you may perform a corona treatment on the surface of the film 4 beforehand.

It is important that the thickness of the transparent resin film 4 is 150 micrometers or more, Preferably it is 175 micrometers or more, Preferably it is important that it is 175 micrometers or more, More preferably, it is 175 micrometers-300 micrometers, Especially, thickness 175 is especially It is preferable to use the PET film of micrometer-188 micrometers.

If the thickness of the transparent resin film 4 is 150 micrometers or more, especially 175 micrometers or more, the distortion (shaking) in the reflection beam of the nameplate laminated body (A) and the nameplate formed using this can be eliminated, For example, when looking at the reflection image of a fluorescent lamp, it is possible to remove an abrasion like a tangerine peel, which can dramatically improve the design of the name plate. In addition, since it was difficult to obtain a 150-micrometer transparent resin film at first, it was recognized that the thickness of the PET transparent resin film 4 needs to be 175 micrometers or more, but the 150-micrometer PET film was obtained and tested, Distortion (shaking) in the reflected light could be eliminated. Although the upper limit of the thickness of the transparent resin film 4 is not specifically limited, Since the optical film of the thickness exceeding 300 micrometers is not generally marketed, about 300 micrometers becomes an upper limit at this stage.

A commercial item can also be used as such a metal vapor deposition film 3, For example, a thing of thickness 175 micrometers-188 micrometers is mentioned by a product name: Diecaster AP (made by Reiko Co., Ltd.). However, it is not limited to this.

(Production method)

The manufacturing method of the laminated body (A) for nameplate manufacture which concerns on this embodiment is demonstrated. However, it is not limited to these methods.

It is preferable to manufacture the laminated body (A) for nameplate manufacture which concerns on this embodiment in the production line which manufactures the transparent substrate 1, considering production efficiency, such as mass production and a yield. Specifically, the production line of the transparent substrate 1 is provided by, for example, laying a facility for attaching the metal vapor deposition film 3 to an extension line of production equipment such as an extruder for manufacturing the transparent substrate 1 and a rolling roller. The laminated body (A) for nameplate manufacture can be manufactured continuously in the same line as.

It is preferable to form the transparent substrate 1 continuously by the extrusion method or the continuous cast method, and especially the extrusion method is more preferable since it is excellent in productivity.

Here, the extrusion method is generally a manufacturing method based on a method of melting and extruding a plastic raw material polymer in a pellet state and then cooling and solidifying with a roller to obtain a resin plate.

In addition, the continuous cast method generally supplies a prepolymerized syrup between stainless steel belts that are continuously operated in pairs up and down, and undergoes processes such as heat polymerization, heat treatment, cooling, and peeling with the operation of the belt, It is a manufacturing method based on the method of removing the resin plate continuously from the terminal.

As part of the finishing process of the extrusion method or the continuous cast method, an operation of stretching using a rolling roller to form a transparent substrate to a certain thickness, a structure of a takeout roller for taking a transparent substrate, and the like are appropriately knitted as necessary. can do.

Although the method of attaching the metal vapor deposition film 3 is not specifically limited, Preferably, an adhesive is apply | coated to a release film in advance, it is made to dry, and after attaching the metal vapor deposition film 3 to this adhesion surface, a metal is further added. A protective film is affixed on the surface on the opposite side to the adhesion of the vapor deposition film 3, this is wound up in roll bundle shape, and it is set as a winding roll. And in the manufacturing line of the said transparent substrate 1, while peeling a release film from the metal vapor deposition film 3 unwound by the winding roll, exposing an adhesion layer, the protective film is wound up from the opposite side of the transparent substrate 1 Unrolled from the rolls and attached to the transparent substrate 1 to the transparent substrate 1 by simultaneously passing through the pressing roller while the metal deposited film 3 and its protective film overlap each other on both sides of the transparent substrate 1. Just do it.

At this time, it is preferable that the pressure of the pressing roller is appropriately selected in a range where practical obstacles do not appear depending on the materials of the metal deposition film 3, the transparent substrate 1, and the protective film to be used.

Moreover, it is preferable to perform a series of process of attaching the metal vapor deposition film 3 from the formation of the transparent substrate 1 in a dustproof room, and it is produced when attaching the transparent substrate 1 and the metal vapor deposition film 3 to it. It is preferable to discharge static electricity. In addition, when adhering the metal vapor deposition film 3, it is preferable to adjust the tension of the metal vapor deposition film 3 so that a sheet | seat body may not bend after adhering to the transparent substrate 1.

In addition, in order to further improve designability, black printing may be performed to the whole surface or one part of the back surface of the metal vapor deposition film 3, for example, and the part which black printing was made into a mirror surface part. At this time, since the part which has not performed black printing becomes a part which a light ray permeates on the back surface side, for example, as shown in FIG. 3, the back surface of the metal vapor deposition film 3 except digital display parts, such as a clock display, is shown. By carrying out black printing, the nameplate which also provided the digital display part while providing mirror-shaped metallic luster can be manufactured.

Although the laminated body (A) for nameplate manufacture which concerns on this embodiment can also be manufactured with a series of production lines as mentioned above, it is made by laminating | stacking the adhesion layer 2 and the metal vapor deposition film 3, and the said metal The vapor deposition film 3 forms the metal vapor deposition layer 5 in the single side | surface side of the transparent resin film 4, Comprising: The structure which defines the thickness of this transparent resin film 4 to 150 micrometers-300 micrometers The pressure-sensitive adhesive metal vapor deposition film provided was prepared in advance, and the pressure-sensitive adhesive metal vapor deposition film was separately attached to the transparent substrate 1 through the pressure-sensitive adhesive layer 2 in a production line different from the pressure-sensitive adhesive metal vapor deposition film. The laminated body (A) for nameplate manufacture can also be manufactured.

In the cross section of the sieve (B), since the depth by color tone change comes out, it is more preferable.

(Hard Coat Film (7))

The hard coat film 7 functions to protect the surface of the display panel from scratches and the like when the display panel is produced, for example, using the laminate (B) for name plate production. Therefore, it is preferable that the hard-coat film 7 is equipped with abrasion resistance, and as a reference | standard of abrasion resistance, when making steel wool # 0000 reciprocate 10 stroke x 10 times on a target surface under a load of 1 kg / cm <2>, It is preferable to have a scratch resistance of the extent which a wound is not recognized visually.

(Production method)

The manufacturing method of the laminated body (B) for nameplate manufacture which concerns on this embodiment is demonstrated. However, it is not limited to the manufacturing method demonstrated below.

Basically, since it can manufacture similarly to the said laminated body A for nameplate manufacture, only a different point is demonstrated.

Although the method of attaching the hard coat film 7 is not specifically limited, Preferably, an adhesive is apply | coated to a mold release film previously, and it is made to dry, and the metal vapor deposition film 3 and the hard coat film 7 are made to this adhesive surface. After sticking, a protective film is further stuck to the surface on the opposite side to the adhesion of the metal vapor deposition film 3 and the hard coat film 7, and this is wound up in roll bundle shape, and the mold release adhesion part metal vapor deposition film 3 and mold release are carried out. The hard coat film 7 with an adhesive is each wound up with a winding roll.

And as shown, for example in FIG. 4, in the manufacturing line of the said transparent substrate 1, it is respectively from the release adhesion part metal vapor deposition film 3 and the hard-coat film with release adhesive 7 which were unwound with the take-up roll. The release film is peeled off to expose the pressure-sensitive adhesive layer, while the metal deposition film 3 and the hard coat film 7 are overlapped from both sides of the transparent substrate 1, and the metal is deposited on both sides of the transparent substrate 1 through a crimping roller at the same time. The film 3 and the hard coat film 7 may be attached.

At this time, it is preferable to select the pressure of a crimping roller suitably in the range which does not show practical obstacle according to the material of the transparent substrate 1, the metal vapor deposition film 3, and the hard-coat film 7.

In addition, in the formation of the transparent substrate 1, a series of steps of attaching the metal vapor deposition film 3 and the hard coat film 7 are preferably performed in a dustproof room, and the metal vapor deposition film 3 and the hard coat film ( 7) It is preferable to discharge static electricity generated when attaching. In addition, when attaching the hard-coat film 7, it is preferable to adjust the tension of this film so that a sheet | seat body may not bend after attaching to the transparent substrate 1.

(Usage)

The nameplate production laminated body (B) which concerns on this embodiment processes suitably, such as surface treatment, a decoration process, a printing process, a bending process, a punching process, as needed, and various nameplates, for example, DVD, TV Such as AV equipment such as refrigerators, washing machines, household appliances such as refrigerators and washing machines, mirror products such as cosmetic compact mirrors, nameplates used for vehicles such as automobiles, ships, aircrafts, buildings, toys, and various other mechanical devices. It can be produced).

Especially when using the laminated body (B) for nameplate manufacture which concerns on this embodiment, not only the surface scratch resistance can be improved but the adhesion layers 2 and 6 are formed in both surfaces of the transparent substrate 1, respectively. Therefore, the impact stress at the time of punching process can be largely alleviated with these adhesion layers, and the problem of the whitening of the cross section which became a problem at the time of punching a normal acrylic plate can also be solved.

[Third Embodiment]

As shown in FIG. 5 and FIG. 6, the laminated body (C) for nameplate preparation as 3rd Embodiment is a back surface side (; back side seen from the viewing side, ie, a viewing side) of the transparent substrate 1 which consists of synthetic resins. A laminate for name plate production having a laminated structure formed by sequentially laminating an adhesive layer 2 and a metal vapor deposition film 3 on the surface side opposite to the surface side, and is modified as a base film of the metal vapor deposition film 3. PET film 4A is used.

(Transparent substrate (1))

The transparent substrate 1 can use what consists of synthetic resins among the transparent substrates 1 demonstrated by said 1st Embodiment.

In the case where the transparent substrate 1 is made of a synthetic resin, warping under a high temperature environment becomes a problem, but a predetermined modified PET film is used as the base film forming the base material of the metal vapor deposition film 3 as in the present embodiment. Thereby, the curvature in high temperature environment can also be prevented. Therefore, in this embodiment, it is important to use what consists of synthetic resins as the transparent substrate 1.

(Adhesive layer (2))

The adhesive which comprises the adhesion layer 2 can use the same thing as the adhesive demonstrated in the said 1st Embodiment.

(Metal Deposition Film (3))

The metal vapor deposition film 3 is a laminated | multilayer film which has a structure formed by forming the metal vapor deposition layer 5 in the single side | surface of the modified PET film 4A,

For example, as shown in FIG. 5, the structure formed by forming the metal vapor deposition layer 5 in the surface side of the modified PET film 4A, ie, the adhesion layer 2 side, can also be set as shown in FIG. As described above, the metal vapor deposition layer 5 may be formed on the rear surface side of the modified PET film 4A.

For example, as shown in FIG. 5, when it is set as the metal vapor deposition film which forms the metal vapor deposition layer 5 in the surface side of modified PET film 4A, a metal vapor deposition layer (without exposing the metal vapor deposition layer 5) 5) Corrosion can be prevented and there is no need to form a top coat layer. Moreover, since it is comprised so that a metal mirror surface may be seen, without going through the modified PET film 4A with the highest haze, when seen from the transparent substrate 1 side, haze degree can be reduced and it can be made a more vivid mirror surface.

Also in the case of using the metal vapor deposition film 3 of any structure, it is important to make the thickness of the modified PET film 4A 150 micrometers or more, especially 175 micrometers or more, Preferably it is 175 micrometers-300 micrometers, Especially 175 micrometers It is preferable to set it as -188 micrometers. By setting the thickness of the modified PET film 4A to 150 µm or more, particularly 175 µm or more, distortion (shaking) in the reflected light of the nameplate laminate and the nameplate produced by using the same can be eliminated. For example, when the reflection image of a fluorescent lamp is seen, the abrasion like a tangerine peel can be eliminated, and the design of a nameplate can be improved remarkably. In addition, although the upper limit of the thickness of modified PET film 4A is not specifically limited, Since the optical film of the thickness exceeding 300 micrometers is not generally marketed, about 300 micrometers becomes an upper limit in this stage.

In addition, since it was difficult to obtain a 150 micrometers transparent resin film at the beginning, it was recognized that the thickness of the modified PET transparent resin film 4 should be 175 micrometers or more, but 150 micrometers modified PET film was obtained, As a result of the test, distortion (shake) in the reflected light beam could be eliminated.

Moreover, in addition to being excellent in transparency, modified PET film 4A has the characteristic that the linear expansion coefficient can be adjusted by adjusting and modifying a copolymerization component, As modified PET film 4A used for this embodiment, it is 30 degreeC In the average coefficient of linear expansion at -60 degreeC, the difference with the transparent substrate 1 is less than 3x10 <^-5> / degreeC, Preferably it is within 2x10 <^-5> / degreeC (the difference may be 0). It is important.

If it is modified PET film 4A which satisfy | fills this range, even if it uses high temperature of 60 degreeC vicinity, for example, the difference of the dimensional change accompanying the temperature change of the transparent substrate 1 and the metal vapor deposition film 3 is within a predetermined range. It can suppress and the curvature of a laminated body can be prevented.

As the composition of the modified PET film 4A, for example, a polyester containing a copolyester synthesized from an aromatic dicarboxylic acid component and a glycol component containing ethylene glycol and branched aliphatic glycols or aliphatic glycols, the coefficient of linear expansion Is adjusted to fall within a predetermined range. Preferably, it can adjust with the copolymerization component of Paragraph [0016] of Unexamined-Japanese-Patent No. 2005-66939, and [0038]-[0040], for example, terephthalic acid and ethylene glycol as a main component, and this is diethylene It can be adjusted by copolymerizing glycol and 1-4 butanediol.

Moreover, the modified PET film 4A can also be purchased by specifying the average linear expansion coefficient in 30 degreeC-60 degreeC. For example, as a modified PET film having an average linear expansion coefficient of 5 × 10 ⁻⁵ / ° C. to 8 × 10 ⁻⁵ / ° C., for example, commercially available products such as product name: Soft Shine A1532 (manufactured by Toyo Spinning Co., Ltd.) (Example See, for example, Japanese Patent Application Laid-Open No. 2005-66939, paragraph [0016].

It is preferable to use the biaxially stretched film which is excellent in an optical characteristic for modified PET film 4A. Moreover, in order to improve adhesive force, you may perform a corona treatment on the surface of the film 4 beforehand.

The metal vapor deposition layer 5 can be formed by the method of vacuum-depositing metals, such as aluminum, chromium, nickel, silver, a method of sputtering the said metal, etc., for example. However, it is not limited to these methods.

It is preferable that the metal vapor deposition film 3 is a film provided with the metallic luster by which the total light transmittance by JIS K-7105 will be 50% or less.

Here, in order to prepare the total light transmittance of the metal vapor deposition film 3 to 50% or less, it can implement by adjusting the metal concentration in the metal vapor deposition layer 5, and the line speed at the time of manufacture, for example.

For example, as shown in FIG. 6, in the case of the metal vapor deposition film which forms the metal vapor deposition layer 5 in the back surface side of the modified PET film 4A, a metal vapor deposition layer is influenced by the oxygen and moisture in air. Since it is easy to corrode (especially silver and aluminum), it is preferable to form the corrosion prevention layer (top coat layer) 12.

(Production method)

Next, the manufacturing method of the laminated body (C) for nameplate manufacture which concerns on this embodiment is demonstrated. However, it is not limited to these methods.

It is preferable to manufacture the laminated body (C) for nameplate manufacture which concerns on this embodiment in the production line which manufactures the transparent substrate 1, considering production efficiency, such as mass production and a yield. Specifically, the production line of the transparent substrate 1 is provided by, for example, laying a facility for attaching the metal vapor deposition film 3 to an extension line of production equipment such as an extruder for manufacturing the transparent substrate 1 and a rolling roller. It is possible to manufacture a name plate manufacturing laminate continuously in the same line with.

It is preferable to form the transparent substrate 1 continuously by an extrusion method or a continuous cast method. Here, the extrusion method is generally a manufacturing method based on a method of melting and extruding a plastic raw material polymer in a pellet state and then cooling and solidifying with a roller to obtain a resin plate. In addition, the continuous cast method generally supplies a pre-polymerized syrup between stainless steel belts that are continuously operated in pairs up and down, and undergoes processes such as heat polymerization, heat treatment, cooling and peeling with the operation of the belt, It is a manufacturing method based on the method of removing the resin plate continuously from the terminal. As part of the finishing process of the extrusion method or the continuous cast method, an operation of stretching using a rolling roller to form a transparent substrate to a certain thickness, a structure of a takeout roller for taking a transparent substrate, and the like are appropriately knitted as necessary. can do.

Although the method of attaching the metal vapor deposition film 3 is not specifically limited, Preferably, an adhesive is apply | coated to a release film in advance, it is made to dry, and after attaching the metal vapor deposition film 3 to this adhesion surface, a metal is further added. A protective film is affixed on the surface on the opposite side to the adhesion of the vapor deposition film 3, this is wound up in roll bundle shape, and it is set as a winding roll. And in the manufacturing line of the said transparent substrate 1, the release film is peeled from the metal vapor deposition film 3 unwound by the winding roll, and an adhesive layer is exposed, while the protective film for transparent substrates is unwound from a winding roll, What is necessary is just to make the metal vapor deposition film 3 adhere to the transparent substrate 1 via a crimping roller simultaneously, in the state which superimposed the vapor deposition film 3 and its protective film on both sides of the transparent substrate 1, respectively.

At this time, it is preferable that the pressure of the pressing roller is appropriately selected in a range where practical obstacles do not appear depending on the materials of the metal deposition film 3, the transparent substrate 1, and the protective film to be used.

Moreover, it is preferable to perform a series of process of attaching the metal vapor deposition film 3 from the formation of the transparent substrate 1 in a dustproof room, and it is produced when attaching the transparent substrate 1 and the metal vapor deposition film 3 to it. It is preferable to discharge static electricity. Furthermore, when attaching the metal vapor deposition film 3, it is preferable to adjust the tension of the metal vapor deposition film 3 so that a sheet body may not bend after adhering to the transparent substrate 1 (refer FIG. 4).

In addition, in order to further improve the designability, for example, black printing is performed on the entire surface or a part of the back surface of the metal vapor deposition film 3, so that the black printing portion 9 (black printing portion 9) transmits light. Since it is not, from the viewing side, it is a gloss mirror surface part, and the part which does not perform black printing can be made into the part (transmissive part 10 and 11) through which the light ray in the back surface is transmitted. For example, as shown in FIG. 3, black printing is carried out except for the transmissive portion (digital display portion such as a clock display and a character or symbol portion), thereby providing translucent portions 10 and 11 on the back side while providing a metallic luster in a mirror state. ), You can make a name plate that makes the characters appear by lighting the light. In addition, by printing a product logo, a company name ("Mitsubishi Resin Co., Ltd.", etc.) on the visual side of the transparent substrate 1, the reflection image by the metallic luster is seen from the back surface through the transparent substrate 1, It can also give a three-dimensional design.

In addition, in FIG. 3, time display "13:00" in the permeation | transmission part 10 shows that the liquid crystal screen display provided in the back surface side is visible, and the permeation | transmission part 11 is the back surface of the metal vapor deposition film 3 in FIG. In the black printing section 9 is formed by extracting the letter of "DVD". In addition, since the transmissive portions 10 and 11 are not completely transparent but are half mirrored by a thin vapor deposition layer, when the other side is dark, the transmissive portions are observed in the same manner as the black printed portion 9, and when the light is illuminated from the back side, the transmitted light is transmitted. The display is shown by.

Although the laminated body (C) for nameplate manufacture which concerns on this embodiment can be manufactured by a series of production lines as mentioned above, it is made by laminating | stacking the adhesion layer 2 and the metal vapor deposition film 3, and the said metal vapor deposition The film 3 is formed by forming the metal vapor deposition layer 5 on the single side | surface side of the modified PET film 4A, and is provided with the structure which defines the thickness of the modified PET film 4A to 150 micrometers-300 micrometers. The pressure-sensitive adhesive metal vapor deposition film was prepared in advance, and the pressure-sensitive adhesive metal vapor deposition film was separately attached to the transparent substrate 1 via the pressure-sensitive adhesive layer 2 in a production line different from the pressure-sensitive adhesive metal vapor deposition film. The laminated body (C) for nameplate manufacture can also be manufactured.

(Laminated structure)

The laminated body (C) for nameplate manufacture of this embodiment should just be equipped with the structure formed by laminating | stacking the adhesion layer 2 and the metal vapor deposition film 3 on the back surface side of the transparent substrate 1, For example, you may be provided with the other layer in the visual recognition side (surface side) of the transparent substrate 1, or the back surface side of the metal vapor deposition film 3. As shown in FIG. For example, a hard coat layer can be laminated directly on the viewing side (surface side), the back side, or both surfaces of the transparent substrate 1. At this time, it is preferable that the hard coat film is provided with abrasion resistance, and when the steel wool # 0000 is reciprocated 10 strokes x 10 times under the load of 1 kg / cm <2> on the target surface as a reference | standard of abrasion resistance, It is preferable to have scratch resistance of the extent that a wound is not recognized. When the hard coat film is laminated on the visible side (surface side) of the transparent substrate 1 via the adhesive layer, not only the surface scratch resistance can be improved, but also the adhesive layers are formed on both sides of the transparent substrate 1. Therefore, the impact stress at the time of punching process can be largely alleviated with these adhesion layers, and the whitening problem of the cross section which became a problem when punching a normal acrylic plate can be solved.

Of course, even if it adheres to single side | surface using the modified PET film 4A, since the difference in expansion rate is small, it goes without saying that there exists an advantage that the curvature of the laminated board C for nameplate manufacture obtained is small.

(Usage)
