Description

  The present invention relates to home appliances such as televisions, refrigerators, washing machines, stereos, mirror products such as compact mirrors for makeup, vehicles such as automobiles, ships, aircraft, buildings, playground equipment (ski goggles, etc.), and other various mechanical devices. The present invention relates to a laminate for producing a nameplate having a metallic luster used for producing a nameplate (including a display plate and a panel) used for a kind.

  Conventionally, as a laminate for producing a nameplate with this kind of metallic luster, a hard coat treatment is performed on a transparent substrate in order to improve adhesion to a metal vapor deposition film, and a masking film is formed on the hard coat layer. A structure in which a metal vapor deposition film is formed on this masking film to form a metal vapor deposition film, and a top coat layer is further formed on the metal vapor deposition film is disclosed (paragraph [0028]-[ 0034] and FIG. 4).

  Moreover, while providing a metal vapor deposition decorative pattern on one side of a substrate (PET film) using a metal transfer foil, a metallic gloss film, etc., an adhesive layer is provided on the opposite side to form a decorative sheet. In-mold molded product obtained by inserting the decorative sheet formed in the mold into an in-mold molding die and injecting molten resin (the main application is a display window used for a liquid crystal display of a portable information terminal device) Is disclosed (see paragraph [0019] etc. of Patent Document 2).

JP 2001-266687 A Japanese Patent Laid-Open No. 2004-50778

  However, the laminate for producing a nameplate having the configuration disclosed in Patent Document 1 must be manufactured by a single wafer method in which metal deposition is performed on each transparent plate when forming a metal deposition film. Therefore, it is difficult to produce continuously on a series of production lines, the production efficiency is poor, it is difficult to widen the sheet, and the number of processes increases, making it difficult to manage foreign matter and scratches. He had a problem that the yield was bad.

On the other hand, as disclosed in Patent Document 2, a metal vapor-deposited layer is provided on one surface of a PET film, for example, using a metal transfer foil or a metallic gloss film, and an injection resin is laminated on the opposite surface via an adhesive layer. In the structure having the structure, 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 at the time of transfer or injection molding of the metal transfer foil, and the reflected light is distorted (also referred to as “fluctuation”). Say) occurs. For example, when the reflection image is viewed by placing it on a fluorescent lamp, there is a problem that countless scars such as a yuzu skin appear on the surface of the laminate.
In addition, when a metal transfer foil is used, irregularities (coating irregularities) are formed at the interface between the corrosion prevention layer and the metal layer or at the interface between the metal layer and the adhesive layer when the transfer foil is applied. There was a problem that distortion of reflected light occurred in itself.
As described above, in-mold injection-molded products using a metallic gloss film or a metal transfer foil can be produced at a relatively low cost, but have a problem that they are inferior in design as compared with those in which metal is directly deposited on a transparent substrate. Was.

  Therefore, the present invention can be produced easily and in large quantities with good yield, and there is no distortion (fluctuation) due to reflected light. Specifically, when the reflected image of a fluorescent lamp is viewed, It is intended to provide a new laminate for producing nameplates in which no scars are visible.

In the present invention, an adhesive layer 2 and a metal vapor deposition film 3 are laminated in order from the viewing side (also referred to as “front side”) on the back side of the transparent substrate 1 made of a synthetic resin (the back side when viewed from the viewing side). A laminated body for producing a nameplate having a metallic luster having a laminated structure, wherein the metal vapor-deposited film 3 has a configuration in which the metal vapor-deposited layer 5 is laminated on one side of the modified PET film 4, and The modified PET film 4 has a difference in average linear expansion coefficient from 30 ° C. to 60 ° C. within the range of 3 × 10 ⁻⁵ / ° C. and a thickness of 175 μm to 300 μm. We propose a laminate for producing nameplates with a metallic luster characterized by

  The laminate for producing a nameplate having such a configuration is a laminate for producing a nameplate having a configuration in which, for example, black printing is performed on the entire back surface or a part of the metal vapor-deposited film 3, and the black-printed portion is used as a mirror surface portion. It can be a body.

The laminate for producing a nameplate according to the present invention having the above-described structure includes a metal vapor deposition film 3 on the back side of the transparent substrate 1 made of a synthetic resin, and the refraction of light due to the thickness of the transparent substrate 1 and the metal vapor deposition film 3. The glossy appearance can make the appearance look deep metallic.
Further, by defining the thickness of the modified PET film 4 that forms the base of the metal vapor deposition film 3 and is located on the back surface of the metal vapor deposition layer 5, the occurrence of distortion (fluctuation) due to reflected light rays is eliminated. When looking at the reflected image of the fluorescent lamp, it is possible to prevent scratch marks such as a yuzu skin from appearing.
This point will be described in detail. Generally, when a polyethylene terephthalate (hereinafter referred to as “PET”) film and an adhesive layer are laminated on a metallic gloss film, a transparent film substrate of 50 μm to 100 μm is often used ( For example, refer to paragraph [0019] of Japanese Patent Application Laid-Open No. 2004-50778. In this case, the reflected light is distorted. There was a problem that occurred. Therefore, the inventors have investigated the cause of this, and it is caused by infinite irregularities at the interface between the film and the adhesive layer, and by increasing the thickness of the base film, innumerable irregularities can be eliminated. I found what I could do.

The laminate for producing a nameplate of the present invention has a difference in average linear expansion coefficient at 30 ° C. to 60 ° C. as compared with the transparent substrate 1 as 3 × By using a modified PET film having a temperature of 10 ⁻⁵ / ° C. or less, warpage in a high temperature environment can be prevented.
Furthermore, the metal vapor deposition film 3 is pressure-bonded to one side surface of the transparent substrate 1 through the adhesive layer 2 in an extension line of the production line that continuously forms the transparent substrate 1 by, for example, an extrusion method or a continuous casting method. Since it can be manufactured continuously by sticking with a roller, it can be efficiently produced, and the width of the sheet can be easily widened. It also has the feature of good yield.
The above-described extrusion method or continuous casting method generally includes methods that can be generally regarded as an extrusion method or a continuous casting method, and these can be freely used in the present invention.

The present invention proposes a laminate for producing a nameplate having a constitution in which a colorant is included in the pressure-sensitive adhesive layer 2 in the laminate for producing a nameplate according to the present invention, as a new laminate for producing a nameplate having a colored metallic luster. .
By the way, if coloring is applied to the laminate for producing a nameplate having a metallic luster, it has been usual to add a colorant to the transparent substrate 1, but production of a transparent substrate (extrusion method, casting method, etc.) Adding a colorant in the process and producing a small amount not only increases the number of processes and increases the manufacturing cost, but also when the transparent substrate 1 is colored by adding a colorant, the color change changes due to a subtle difference in thickness. In addition, the thickness control is very difficult.
On the other hand, if the colorant is included in the pressure-sensitive adhesive layer 2 located on the back side of the transparent substrate 1 in the structure for producing a nameplate according to the present invention, the color of the transparent substrate 1 changes even if the thickness thereof changes. It does not change the taste, and can express light colors such as light blue and pink. Moreover, when the end surface of the transparent substrate is viewed obliquely through the transparent substrate, it is possible to obtain a new design effect that the color change greatly changes depending on the viewing angle, and the design of the nameplate can be dramatically improved.

  As described above, the laminate for producing nameplates according to the present invention can be produced easily and in large quantities with good yield, and there is no occurrence of distortion (fluctuation) due to reflected light. Specifically, a reflected image of a fluorescent lamp is observed. The design of the nameplate can be drastically improved by making the scars such as Yuzu skin invisible. In addition, it is possible to prevent warpage in a high temperature environment, and it is also possible to easily and inexpensively produce a colored metal transparent nameplate, which has been high in production cost and has not been widely spread.

Embodiment of the Invention

Next, this invention is demonstrated based on embodiment.
However, the embodiment described below is an example of the embodiment of the present invention, and the scope of the present invention is not limited to the following embodiment.

In addition, when expressed as “main component” or “main agent” in the present specification, it includes the intention to allow other components to be contained within a range that does not interfere with the function of the main component, unless otherwise specified. Is. In particular, the content ratio of the main component is not specified, but the component (when two or more components are main components, the total amount thereof) is 50% by mass or more, particularly 70% by mass or more in the composition. Is generally occupied.
In this specification, when “X to Y” (X and Y are arbitrary numbers) is described, it means “X or more and Y or less” unless otherwise specified, and “preferably larger than X, Y It includes the meaning of “smaller”.

  As shown in FIG. 1 and FIG. 2, the laminate for producing a nameplate according to the present embodiment is the back side of the transparent substrate 1 made of a synthetic resin (the back side when viewed from the viewing side, that is, the front side that is the viewing side). It is a laminate for producing a name plate having a laminated structure in which an adhesive layer 2 and a metal vapor-deposited film 3 are sequentially laminated on the side opposite to the side.

(Transparent substrate 1)
The shape and material of the transparent substrate 1 are not particularly limited as long as it is transparent and flat, but is preferably made of a transparent resin that can be reduced in weight or thickness. Specifically, polymethylmeth (a) acrylate (PMMA) resin, polycarbonate (PC) resin, methyl methacrylate-styrene copolymer resin (MS resin), polyarylate resin, polysulfone resin, polyethersulfone resin, norbornene resin and It is preferable that the transparent substrate is composed mainly of at least one member selected from the group consisting of cycloolefin (alicyclic) resins.

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

  The transparent substrate 1 may be a single-layer plate or a multilayer plate composed of two or more layers. For example, as the transparent substrate 1, it is possible to use a transparent substrate in which a hard coat layer is laminated on one side surface or both side surfaces of a substrate made of a transparent resin. In this case, as the hard coat layer, for example, a composition containing an ultraviolet curable polyfunctional (meth) acrylate, an ultraviolet absorber, a photocuring initiator, colloidal silica, an inorganic or organic filler, and the like is formed by coating. Things can be mentioned. However, the present invention is not limited to this.

The thickness of the transparent substrate 1 is not particularly limited, but is preferably set as appropriate in the range of 0.5 mm to 10 mm.
At this time, as the thickness of the transparent substrate 1 is increased, the appearance can be deepened and a high-class feeling can be produced. However, it is usually 2 mm to 7 mm, particularly preferably 2 mm to 5 mm.
Further, in the thickness of the transparent substrate 1, it is also preferable to consider a processing method. For example, in the case of punching, 0.5 mm to 1.5 mm is obtained from the viewpoint of obtaining a good appearance with little whitening of the end face. It is preferable to set in the range.

  The transparency of the transparent substrate 1 is preferably such that the total light transmittance according to JIS K-7105 is 85% or more and less than 1% of haze.

(Adhesive layer 2)
For the adhesive layer 2, commonly used UV curable and thermosetting adhesives can be used. Among them, the viscoelasticity at 180 ° C. is 1 × 10 ⁵ Pa to 1 × 10 ⁶ Pa, particularly 2 ×. preferable to use 10 ⁵ consisting Pa~5 × 10 ⁵ Pa at a transparent resin adhesive. If the pressure-sensitive adhesive satisfies this range, the pressure-sensitive adhesive layer 2 has elasticity that exceeds the foaming force of the outgas against the outgas generated from the transparent substrate 1 in a high-temperature / humid heat environment. 2, foaming, peeling, floating, etc. at the interface between the metal vapor deposition film 3 and the adhesive layer 2 can be suppressed. In addition, when pasting with an adhesive, it is generally necessary to autoclave in order to advance wetting. However, if the adhesive satisfies the above range, there is no need to autoclave, and a high temperature and high humidity test. The durability in (for example, 60 ° C. and 95% RH, left for 168 hours) can be improved.

  The composition of the pressure-sensitive adhesive is, for example, a (meth) acrylic acid ester-based copolymer mainly comprising an alkyl (meth) acrylate, a functional group-containing monomer, and a (meth) acryloyl group-containing copolymer. And those having a molecular weight of about 500,000 to 2,000,000 as a main ingredient. Examples of such (meth) acrylic acid ester-based copolymers include those obtained by copolymerizing 2-ethylhexyl acrylate, n-butyl acrylate, acrylic acid, and other monomers (macromonomer or vinyl monomer). it can.

Further, in order to adjust the cohesive force and viscoelasticity of the pressure-sensitive adhesive, those obtained by adding a polyfunctional compound capable of forming a crosslinked structure between the (meth) acrylic acid ester copolymers as a crosslinking agent are preferable. .
In this case, examples of the crosslinking agent include an isocyanate compound, an epoxy compound, an amine compound, a metal chelate compound, and an aziridine compound. Examples of the epoxy compound include bisphenol A, ethylene glycol glycidyl ether, and glycerin. Diglycidyl ether and the like can be mentioned. Examples of the amine compound include hexamethylene diamine and triethyl diamine. Examples of the metal chelate compound include aluminum, iron, copper, zinc, tin, titanium, nickel, and antimony. , Magnesium, vanadium, chromium, and other polyvalent metals are coordinated to acetylacetone and ethyl acetoacetate. Examples of the aziridine compounds include triethylenemelamine.
Such a cross-linking agent may be usually blended in an amount of 0.001 to 0.1 parts by mass with respect to 100 parts by mass of the main component (for example, acrylic resin component), and the type and addition amount of the cross-linking agent are adjusted. By doing so, the viscoelasticity of the pressure-sensitive adhesive can be adjusted to the above range.

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

Commercially available products can be used as the pressure-sensitive adhesive satisfying the above conditions. For example, “Product Name SK Dyne 1882” (180 ° C. Viscoelasticity: 3.1 × 10 ⁵ Pa) manufactured by Soken Chemical Co., Ltd. “Product Name SK Dyne 1888” (180 ° C. Viscoelasticity manufactured by Soken Chemical Co., Ltd .: 2.5 × 10 ⁵ Pa) or the like can be used.

Moreover, a metallic luster can be colored to a desired color by adding a coloring agent to the adhesive layer 2, and a colored metallic luster can be imparted to the nameplate working laminate and a nameplate produced therefrom.
What is necessary is just to add colorants, such as an organic pigment and dye, as a colorant mix | blended with the adhesion layer 2. FIG. Of these, 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, phthalocyanine pigment as a blue pigment, indanthrene blue pigment, quinacridone pigment as a red pigment, watching pigment, permanent pigment, anthraquinone pigment, etc. Any one or two or more of these can be used in appropriate combination. In that case, the hue can be adjusted by the blending ratio of the pigment.

  The thickness of the adhesive layer 2 is preferably 10 μm to 30 μm. In order to obtain an adhesive force, it is more preferably 15 μm or more. On the other hand, if it exceeds 30 μm, the adhesive surface may be greatly roughened during the adhesive coating, and the appearance may be deteriorated. From such a viewpoint, the thickness of the pressure-sensitive adhesive layer 2 is more preferably 15 μm to 25 μm.

  The pressure-sensitive adhesive layer 2 formed on the transparent substrate 1 can relieve impact stress at the time of punching, and when an ordinary acrylic plate is punched, the end face is whitened. To fulfill.

(Metal vapor deposition film 3)
The metal vapor deposition film 3 is a laminated film having a configuration in which the metal vapor deposition layer 5 is formed on one side of the modified PET film 4.
For example, as shown in FIG. 1, a configuration in which a metal vapor deposition layer 5 is formed on the surface side of the modified PET film 4, i.e., the adhesive layer 2 side, is also possible. It can also be set as the structure formed by forming the metal vapor deposition layer 5 in the back surface side.

  For example, as shown in FIG. 1, if a metal vapor deposition film is formed by forming a metal vapor deposition layer 5 on the surface side of the modified PET film 4, corrosion of the metal vapor deposition layer 5 is prevented without exposing the metal vapor deposition layer 5. This eliminates the need for a topcoat layer. Moreover, since the metal mirror surface is viewed without passing through the modified PET film 4 having the highest haze when viewed from the transparent substrate 1 side, the degree of haze can be reduced and a clearer mirror surface can be obtained. .

  In the case of the metal vapor deposition film 3 having any configuration, it is important that the thickness of the modified PET film 4 is 175 μm or more, preferably 175 μm to 300 μm, particularly preferably 175 μm to 188 μm. By setting the thickness of the modified PET film 4 to 175 μm or more, it is possible to eliminate distortion (fluctuation) in the reflected light of the nameplate laminate and the nameplate produced using this, for example, a reflected image of a fluorescent lamp When viewed, scratches such as yuzu skin can be eliminated, and the design of the nameplate can be greatly improved. In addition, although the upper limit of the thickness of the modified PET film 4 is not particularly limited, an optical film having a thickness exceeding 300 μm is generally not commercially available, and thus the upper limit is about 300 μm at this stage.

The modified PET film is excellent in transparency, and has a feature that the linear expansion coefficient can be adjusted by adjusting and modifying the copolymer component, and the modification used in the present embodiment. The PET film 4 has a difference in average linear expansion coefficient between 30 ° C. and 60 ° C. within 3 × 10 ⁻⁵ / ° C., preferably within 2 × 10 ⁻⁵ / ° C. (the difference is 0). It is important to use what may be.
If the modified PET film 4 satisfies this range, for example, even when used at a high temperature around 60 ° C., the difference in dimensional change accompanying the temperature change between the transparent substrate 1 and the metal vapor deposited film 3 can be suppressed within a predetermined range. Warpage of the laminate can be prevented.

The composition of the modified PET film 4 is, for example, a polyester containing a copolyester synthesized from an aromatic dicarboxylic acid component and ethylene glycol and a branched aliphatic glycol or a glycol component containing an aliphatic glycol, and has a linear expansion coefficient. Can be adjusted so as to fall within a predetermined range. Preferably, it can be adjusted by a copolymerization component described in paragraphs [0016] and [0038] to [0040] of JP-A-2005-66939, for example, containing terephthalic acid and ethylene glycol as main components. Diethylene glycol and 1-4 butanediol can be copolymerized and adjusted.
In addition, the modified PET film 4 can also be purchased by designating an average linear expansion coefficient at 30 ° C. to 60 ° C. For example, as a modified PET film having an average linear expansion coefficient of 5 × 10 ⁻⁵ / ° C. to 8 × 10 ⁻⁵ / ° C., there is a commercial product such as a product name: Soft Shine A1532 (manufactured by Toyobo Co., Ltd.) ( For example, see paragraph [0016] of JP-A-2005-66939.

  For the modified PET film 4, it is preferable to use a biaxially stretched film having excellent optical properties. In order to increase the adhesion, the surface of the film 4 may be subjected to corona treatment in advance.

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

The metal vapor-deposited film 3 is preferably a film having a metallic luster in which the total light transmittance according to JIS K-7105 is 50% or less.
Here, the total light transmittance of the metal vapor-deposited film 3 can be adjusted to 50% or less, for example, by adjusting the metal concentration in the metal vapor-deposited layer 5 or the line speed during production.

  For example, as shown in FIG. 2, in the case of a metal vapor deposition film in which the metal vapor deposition layer 5 is formed on the back side of the modified PET film 4, the metal vapor deposition layer is easily corroded by the influence of oxygen and moisture in the air. It is preferable to provide a corrosion prevention layer (topcoat layer) 6 (especially silver or aluminum).

(Production method)
Next, the manufacturing method of the laminated body for nameplate preparation concerning this embodiment is demonstrated. However, it is not limited to these methods.

  The laminate for producing a nameplate according to the present embodiment is preferably manufactured on a production line for manufacturing the transparent substrate 1 in consideration of production efficiency such as mass production and yield. Specifically, for example, by attaching a facility for bonding the metal vapor deposition film 3 to an extension line of a manufacturing facility such as an extruder and a rolling roller for manufacturing the transparent substrate 1, the same line as the production line of the transparent substrate 1 is provided. Thus, a laminate for producing a nameplate can be manufactured continuously.

  The transparent substrate 1 is preferably formed continuously by an extrusion method or a continuous casting method. Here, the extrusion method is generally a production method based on a method of obtaining a resin plate by melting and extruding a pellet-shaped plastic raw material polymer and then cooling and solidifying with a roller. In addition, the continuous casting method is generally a prepolymerized syrup supplied between a stainless steel belt that is continuously operated in a pair of upper and lower sides, and heat polymerization, heat treatment, cooling and peeling as the belt operates. It is a manufacturing method based on a method of continuously taking out a resin plate from the end through the above-described steps. As part of the finishing process of the extrusion method or continuous casting method, the operation of stretching using a rolling roller to form a transparent substrate to a constant thickness, the mechanism of the take-up roller for taking up the transparent substrate, etc. It can be incorporated as necessary.

The method of bonding the metal vapor-deposited film 3 is not particularly limited. Preferably, a pressure-sensitive adhesive is previously applied to the release film and dried, and the metal vapor-deposited film 3 is bonded to the pressure-sensitive adhesive surface, and then rolled. It is wound into a bundle and set as a take-up roll. And in the production line of the said transparent substrate 1, while peeling a release film from the metal vapor deposition film 3 drawn | fed out from the winding roll and exposing an adhesion layer, a protective film for transparent substrates is drawn out from a winding roll, and metal The vapor deposition film 3 and the protective film may be laminated on both sides of the transparent substrate 1 and simultaneously passed through a pressure roller so that the metal vapor deposition film 3 is bonded to the transparent substrate 1.
At this time, it is preferable that the pressure of the pressure roller is appropriately selected within a range that does not impede practically according to the materials of the metal vapor deposition film 3, the transparent substrate 1, and the protective film to be used.

  Moreover, it is preferable to perform a series of processes for bonding the metal vapor deposition film 3 from the formation of the transparent substrate 1 in a dustproof chamber, and it is preferable to remove static electricity generated when the transparent substrate 1 and the metal vapor deposition film 3 are bonded. . Furthermore, when the metal vapor deposition film 3 is bonded, it is preferable that the sheet body is not warped after being bonded to the transparent substrate 1 by adjusting the tension of the metal vapor deposition film 3 (see FIG. 4).

  In order to further improve the design, for example, the black print 9 can be applied to the entire or part of the back surface of the metal vapor-deposited film 3, and the portion with the black print 9 can be used as the mirror surface portion 10. At this time, the portion not subjected to the black printing 9 becomes a portion through which light is transmitted from the back side (translucent portion 11). For example, as shown in FIG. By applying the black print 9 on the back surface of 3, a name plate having a mirror-like metallic luster and also having a digital display portion can be produced.

(Laminated structure)
The laminate for producing nameplates of the present embodiment only needs to have a configuration in which the adhesive layer 2 and the metal vapor deposition film 3 are sequentially laminated on the back surface side of the transparent substrate 1. Side) or another layer on the back side of the metal vapor-deposited film 3. For example, a hard coat layer is laminated directly on the viewing side (front side) or back side or both sides of the transparent substrate 1, or a hard coat film is laminated on the viewing side (front side) of the transparent substrate 1 via an adhesive layer. It is arbitrary to do. At this time, it is preferable that the hard coat film has scratch resistance. As a standard of scratch resistance, steel wool # 0000 is reciprocated 10 cm × 10 times on the target surface under a load of 1 kg / cm ^2. It is preferable to have scratch resistance such that no scratches are visually confirmed. When a hard coat film is laminated on the visual recognition side (front surface side) of the transparent substrate 1 via an adhesive layer, not only the surface scratch resistance can be improved, but also an adhesive layer is formed on both surfaces of the transparent substrate 1. The impact stress at the time of punching can be greatly relieved by these adhesive layers, and the problem of whitening of the end face, which has been a problem when punching a normal acrylic plate, can be solved.

(Use)
The laminate for producing nameplates according to the present embodiment is subjected to appropriate processing such as surface treatment, decoration, printing, folding, punching, etc. as necessary, and various nameplates such as AV equipment such as DVD and TV, Nameplates (including display plates and panels) used in household appliances such as refrigerators and washing machines, mirror products such as compact mirrors for makeup, vehicles such as automobiles, ships, aircraft, buildings, playground equipment, and other various mechanical devices ) Can be produced.

The linear expansion coefficient was increased from room temperature to 2 ° C./minute while applying a minute load with a thermal stress strain measuring device (TMA-SS / 120C) manufactured by SII Nanotechnology Co., Ltd. This is a value obtained by measuring the linear expansion coefficient from the temperature dependence of the amount (the same applies to the following examples and comparative examples).
