Description

  The present invention relates to a transfer foil that is used by being transferred to an article, and relates to a transfer foil that can be used for prevention of counterfeiting and authenticity determination, and further has an optical effect that enhances design properties. In particular, the present invention relates to a transfer foil used for a transfer object having a rough surface such as a cloth and having elasticity, and a method for producing the same.

Conventionally, an optical effect element such as a hologram has been used to show the authenticity of a medium to which it is attached. In addition to paper and cards, examples of media that can be attached to clothing such as artificial leather, woven fabric, non-woven fabric, and leather, and clothes such as transfer foil disclosed in Patent Document 1 are increasing.
By attaching an optical effect element to a medium such as a product, it is possible to give the medium a high-class feeling and increase its value, and to suppress damage caused by a counterfeit or counterfeit medium.
However, in the case of a medium such as cloth, the conventional transfer foil has some problems due to its large stretchability and rough surface.

Normally, when a transfer foil containing a metal reflective layer is transferred to a transfer target, the outermost surface of the transfer target becomes a smooth surface. And will shine.
As a result, the surface of the region transferred from the transfer foil may stand out unnecessarily, making it difficult to see the pattern of the lower substrate on the surface of the transfer target, or preventing optical effects such as holograms and color shifts.

Here, the above situation will be described with reference to FIGS.
FIG. 4 is a schematic cross-sectional view showing an example of a layer structure of a conventional transfer foil. FIG. 5 is a schematic cross-sectional view showing an example of a transfer product using a conventional transfer foil. FIG. 6 is a schematic view showing an example of a transfer product (cloth) using a conventional transfer foil.

Conventional transfer foils are usually composed of a laminate of a plurality of layers. Typically, as shown in FIG. 4, for example, a release layer (2) and a protective layer on a support (1) such as a plastic film. The transfer foil laminated | stacked in order of the layer (3) and the contact bonding layer (4) is mentioned.
Furthermore, other layers may be included as necessary. For example, when optical effects such as holograms and color shifts are imparted, metal reflection is partially reflected between the protective layer (3) and the adhesive layer (4), which are transferred to the transfer target, using a technique such as vacuum deposition. A layer structure provided with the layer (6) is also often used.

When the adhesive layer (4) is pressure-bonded to the surface of the transfer object (7) using this transfer foil and heated with a hot roll or the like from the support (1) side, the adhesive layer (4) is transferred to the transfer object (7). ) And peeled from the interface (5) between the release layer (2) and the protective layer (3) to obtain a transfer product.
FIG. 5 schematically shows the layer structure of the transfer product thus obtained.
In the transfer product of FIG. 5, a transparent protective layer (3) is formed on the surface of the transfer object (7) via an adhesive layer (4) on the outermost surface. The transparent protective layer (3) and the adhesive layer Between (4), a partially provided metal reflective layer (6) is disposed.

The transferred material as shown in FIG. 5 has not only a defect in appearance but also a physical property as a surface layer having an optical effect used for a transfer material having a soft surface and a high elasticity such as a cloth. There were some problems left.
One of them is that the outermost surface of the transferred product in the transfer area after the transfer becomes a smooth surface. As indicated by the arrows in FIG. It is reflected and shines, and a so-called Tecateka feeling appears.

  Originally, in order to provide an optical effect such as hologram or color shift by the optical effect layer, it is necessary that the light reflected by the partially provided metal reflection layer (6) has excellent visibility. Since the light reflected by the outermost surface of the protective layer (3) becomes difficult to see the light reflected by the metal reflective layer (6), the optical effect is inferior.

  Further, since the outermost surface of the transfer region of the transfer product is smooth, the light reflected on the outermost surface is reflected and shines even in the transparent region without the metal reflection layer, and the transfer region becomes uselessly conspicuous. This problem is particularly noticeable in a transfer object such as a cloth having a non-glossy surface, and causes a disadvantage that the pattern on the transfer object surface becomes difficult to see.

FIG. 6 shows a metal reflective layer (6) partially provided on an object to be transferred (7) such as cloth via an adhesive layer (4) and a protective layer (3) on the outermost surface thereon. The schematic diagram seen from the surface side is shown.
The protective layer (3) is transparent, and it is desirable that the metal reflective layer (6) and the transfer target (7) partially provided through the protective layer (3) can be seen when viewed from the surface side. The inconvenience as described above occurs due to the smooth surface.

Another problem is that when a material such as a cloth having a rough surface and having elasticity and flexibility to bend is used as the transfer object (7), the transferred layer, particularly the metal reflection layer (6), is used. It is easy to crack.
In particular, as a transfer foil to a stretchable and flexible material, the transferred film is required to follow the surface of the material to be transferred, so cracks in the metal reflective layer with less stretchability are more likely to enter. Become.
If the metal reflective layer (6) is cracked, the optical effect layer cannot sufficiently exhibit optical effects such as holograms and color shifts, so that the design effect is lowered. In addition, it is conceivable that the accuracy of necessary determination and the like is hindered for use in authenticity determination.

  Because of the above circumstances, an optical effect layer that suppresses unnecessary reflected light from the outside surface after transfer and is difficult to break due to changes due to bending of the base material even if the transfer target is flexible such as cloth. The transfer foil provided was desired.

JP-A-9-179480

  The present invention suppresses unnecessary external light reflected light on the surface after transfer, and is provided with an optical effect layer that is difficult to break due to a change caused by bending of the substrate even if the transfer target is a flexible material such as a cloth. It aims at providing foil and its manufacturing method.

  The invention according to claim 1 of the present invention is a transfer foil having an optical effect layer containing particles having a diameter of 1 μm or less at a ratio of 50% or more and having a thickness of 2 times or less the average particle diameter of the particles. In the transfer foil, the uneven particle shape of the optical effect layer is exposed on the outermost surface after transfer.

  The invention according to claim 2 is the transfer foil according to claim 1, wherein a reflective layer is provided on at least a part of the surface of the particle.

  The invention according to claim 3 is a transfer foil that is pasted on a base material that is formed by periodically or randomly arranging a single fiber or a yarn in which fibers are twisted together, and has an average particle diameter of the particles The transfer foil according to claim 1 or 2, wherein is smaller than a diameter of the fiber or the yarn.

  The invention according to claim 4 is an article transferred using the transfer foil according to any one of claims 1 to 3.

  The invention according to claim 5 is characterized in that the coating liquid containing the particles is applied and formed on a release layer, and then the surface of the particles is lifted to the release layer side by pressing with a roller. The transfer foil manufacturing method according to any one of the above.

  The transfer foil according to claim 1 of the present invention includes an optical effect layer that contains particles having a diameter of 1 μm or less at a ratio of 50% or more and is provided with a thickness that is twice or less the average particle diameter of the particles. The transfer foil is a transfer foil that is exposed on the outermost surface after transfer, so that unnecessary external light reflected light on the surface after transfer is suppressed, and the transferred object is a cloth. Even if it is a flexible thing like this, it can be set as the transfer foil provided with the optical effect layer which is hard to break by the change by the bending of a base material.

  The optical effect layer on the surface after transfer of the fabric or the like to be transferred is an aggregate of particles having a diameter of 1 μm or less which is smaller than the fiber seam of the fabric base and hardly causes white turbidity. By exposing the surface to the outermost surface, it is possible to eliminate the feeling of tickiness in the transparent region of the transfer region, particularly without the reflective layer.

  When particles having a diameter exceeding 1 μm are used as the particles, the optical effect layer becomes very cloudy and becomes opaque. In addition, when the content ratio of the particles is small, particularly when the ratio is less than 50% of the optical effect layer, the surface unevenness is small, and it is difficult to suppress the unnecessary reflected light from outside light and to eliminate the feeling of ticker.

The transfer foil according to the present invention, particularly when transferred to a cloth base material, gives a sense of texture due to reflection of external light on the surface of the transfer region due to the unevenness of the fiber surface of the cloth base material and the unevenness of the particles exposed on the surface of the base material after transfer. Becomes less noticeable.
Since the region where the metal reflective layer is applied is not a continuous plane but an aggregate of particles, cracks are unlikely to occur when the cloth base material is bent, and the optical effect layer is difficult to break.
When the thickness of the optical effect layer exceeds twice the particle diameter, the particle surface exposed to the surface of the transferred material after transfer is reduced, and the effect of reducing the feeling of tickiness due to external light reflection caused by the irregularities on the particle surface is scarce. End up.

  Furthermore, by providing the reflective layer partially so as to be in contact with the particles, it is possible to improve the design of the transferred material, for example, a pattern can be formed with or without the reflective layer when viewed from the surface of the transferred material.

  According to the transfer foil according to claim 3, the transfer foil is affixed on a base material configured by arranging a single fiber or a yarn in which fibers are twisted together periodically or randomly, and When the average particle diameter is smaller than the diameter of the fiber or the yarn, the separated particles can maintain strength even on a highly stretchable substrate.

  In addition, the reflective layer such as a metal foil formed on the particles does not crack on the particle surface in accordance with the expansion and contraction of the substrate. Since only the cracks enter the metal foil between the particles, there is also an advantage as a design effect that the cracks of the reflective layer are hardly noticeable in appearance.

  According to the invention of claim 5, the coating liquid containing the particles is applied and formed on the release layer, and then the applied coating film is pushed toward the release layer side with a roller to release the surface of the particles. Raise to the mold layer side.

By pressing with a roller, the uneven shape of the particle surface is formed on the release layer side and is raised, so that unevenness occurs on the outermost surface of the article when transferred to the transfer target.
As a result, it is possible to stably and easily manufacture a transfer foil having an effect that light reflected from the outermost surface of the article is scattered and reflected in various directions to reduce the feeling of tickiness due to reflection of external light.

FIG. 2 is a schematic cross-sectional view showing an example of a transfer product using the transfer foil of the present invention. FIG. 3 is a schematic view showing an example of a transfer product (cloth) using the transfer foil of the present invention.

  The transfer foil according to the present invention is a transfer foil having an optical effect layer (10) containing particles having a diameter of 1 μm or less in a proportion of 50% or more and having a thickness of twice or less the average particle diameter of the particles. In this transfer foil, the uneven shape of the particles (12) of the optical effect layer (10) is exposed on the outermost surface of the transfer product after transfer.

FIG. 2 shows a cross section of an example of a transfer product using this transfer foil.
The optical effect layer (10) transferred from the transfer foil is exposed on the surface of the transferred product after the transfer, and a partially provided metal reflective layer (6) is present in a part of the region.
The light from the outside indicated by the arrows in the figure reflects light (8) reflected by the surface of the partially provided metal reflective layer (6) and light (9) diffusely reflected by the surface of the exposed particles (12) and shown in the figure. However, there is light reflected from the surface of the transfer object (7).

  The light (8) reflected by the metal reflective layer (6) is important for ensuring the visibility of the optical effect, and the irregular reflection of the light (9) reflected from the surface of the particles eliminates the sense of tecateka in this region. Helps to avoid standing out unnecessarily.

FIG. 3 shows an example of the transfer product when the transfer object is a cloth.
There is a square transfer area (10) in the center of the figure from the top of the cloth (7) (the front side of the paper) as the transfer object, and a metal reflection layer (6) provided in a circle is located at the approximate center. doing.

First, as shown in FIG. 7, a release layer (2) is formed on the surface of a support (1) made of a heat resistant film such as a polyethylene terephthalate film.
A resin film or sheet is used for the support (1). Examples of the resin include films and sheets made of polyethylene terephthalate resin, polyethylene naphthalate resin, polyimide resin, polyethylene resin, polypropylene resin, heat-resistant polyvinyl chloride resin, and the like. Can be mentioned.

Among these resins, in particular, a sheet or film of stretched polyethylene terephthalate resin is often used because of its relatively high heat resistance and stable film thickness and distribution.
The thickness of the support (1) is preferably about 10 μm to 50 μm. These resin sheets and films are subjected to processing such as antistatic treatment, mat processing, embossing, printing of characters and patterns, laser marking, and the like. Film and sheet can also be used.

The release layer (2) is a layer for transferring the optical effect layer (10) to the transfer target (7) and peeling it from the support (1).
Examples of the main material of the ink as the release layer (2) include acrylic resins such as polymethyl methacrylate. In addition, chlorinated rubber resins, nitrocellulose, acetylcellulose, cellulose acetate butyrate, polystyrene, vinyl chloride, vinyl chloride resin, and the like can be used.

Furthermore, melamine resin, alkyd resin, epoxy resin, etc. can be used, and silicone resin, paraffin wax, reactive fluororesin, etc. can also be used.
The release layer (2) can be formed by a known coating method such as a gravure printing method or a micro gravure method, and the film thickness after drying is preferably 0.5 μm to 5.0 μm.

Further, an optical effect layer (10) is formed on the surface of the release layer (2).
Examples of the material used for the optical effect layer (10) include resins such as thermoplastic resins, thermosetting resins, ultraviolet rays, and electron beam curable resins. Important optical effect layer in the present invention (
Another material used for 10) is spherical particles (12).

Examples of the resin used for the optical effect layer (10) include thermoplastic resins such as acrylic resins, epoxy resins, cellulose resins, and vinyl resins.
In addition, polyurethane resins, melamine resins, phenol resins, and the like obtained by adding polyisocyanate as a crosslinking agent to an acrylic polyol or polyester polyol having a reactive hydroxyl group and crosslinking can be used.
Further, as the ultraviolet ray or electron beam curable resin, epoxy (meth) acryl, urethane (meth) acrylate, or the like can be used.

The spherical particles (12) used for the optical effect layer (10) are made of a colorless or colored transparent material. Usually, the spherical particles (12) are made of a colorless organic or inorganic transparent material.
Examples of organic materials include acrylic resins such as polymethyl acrylate and polymethyl methacrylate, polystyrene resins, polyester resins, polyimide resins, polyolefin resins such as polyethylene and polypropylene, polyamide resins, nylon, polyurethane resins, polychlorinated resins. Vinyl resins, polyvinylidene chloride resins, acrylamide resins, or copolymers containing one or more of them can be used.

  Examples of inorganic materials include calcium carbonate, barium carbonate, magnesium carbonate, calcium silicate, barium silicate, magnesium silicate, calcium phosphate, barium phosphate, magnesium phosphate, silicon oxide, titanium oxide, iron oxide, cobalt oxide, zinc oxide, and oxide. Use nickel, manganese oxide, aluminum oxide, iron hydroxide, nickel hydroxide, aluminum hydroxide, calcium hydroxide, chromium hydroxide, zinc silicate, aluminum silicate, zinc carbonate, basic copper carbonate, zinc sulfide or glass I can do it.

  Examples of the method for forming the optical effect layer (10) include a method of coating and drying a coating solution comprising a resin dissolved in water and dispersed spherical particles (12) by a known method such as a gravure coating method. The coating thickness of the optical effect layer after drying is not particularly limited as long as the required effect can be obtained, but it is as thin as possible (for example, about 0.5 μm) as long as it can be processed and can be stably embossed. Is desirable.

Next, as shown in FIG. 8, heating is performed using a heated rubber roll (11) from the optical effect layer side of the support (1) film on which the release layer (2) and the optical effect layer (10) are formed. Press contact processing is performed. Thus, when the spherical particles (12) dispersed in the optical effect layer (10) are pushed into the release layer (2) and peeled off at the interface between the release layer (2) and the optical effect layer (10), The surface of the optical effect layer (10), which is the outermost surface of the transfer target (7), is an uneven surface where the spherical particles (12) are exposed, and the surface can be made less sensitive to external light reflection.
The heated rubber roll (11) is rotated while applying a required pressure between the heated rubber roll (11) and a flat plate (not shown) from the back surface of the support (1), and spherical particles (12) in the optical effect layer (10) are illustrated. Into the release layer (2) at the top of the plate.

The heating temperature of the rubber roll (11) is not particularly limited as long as the resin of the optical effect layer (10) is softened, and can be determined by the relationship between the softening temperature of the resin and the pressure contact time.
When a normal thermoplastic resin is used for the optical effect layer (10), it is often the case that the processing speed is 40 m / min, the heating temperature is about 160 ° C., and the pressure is about 500 N / cm in linear pressure.

As a method of providing the metal reflection layer (6), a partial vapor deposition method using a mask is often used. The method for uniformly attaching the metal thin film to the uneven surface where the spherical particles (12) are exposed is superior to other methods.
The thickness of the metal reflective layer (6) is mainly determined by the required reflectivity and concealment properties and is not particularly limited, but usually aluminum is often used as the material due to price issues and difficulty of processing. The film thickness may be about 40 nm.

Next, as the adhesive layer (4), a polyamide foil or the like is applied from the opposite surface of the support (1) using a method such as gravure printing to create a transfer foil (see FIG. 10).
The material of the adhesive layer (4) for adhering the optical effect layer (2) to the fabric substrate (7) to be transferred is a polyester resin, acrylic resin, chloride, depending on the material of the transfer target. It can be selected from thermoplastic resins such as vinyl resin, polyamide resin, polyvinyl acetate resin, rubber resin, ethylene-vinyl acetate copolymer resin, vinyl chloride-acetic acid copolymer resin.

  The adhesive layer (4) can be formed by coating and drying by a known method such as gravure printing or microgravure printing. The required film thickness after drying varies depending on the surface state of the transfer object (7), but is preferably in the range of 1 μm to 20 μm.

FIG. 11 shows a cross section of the transferred material in a state where the transfer foil of the present invention prepared as described above is transferred to the transfer target (7) and then peeled off from the peeling interface on the surface of the release layer (2). .
The transfer target (7) is not particularly limited, but the transfer foil of the present invention is most prominent when used for transfer to a cloth substrate made of a woven fabric such as plain weave, twill weave, satin weave and the like. The effect is recognized.

<Comparative Example 1>
A transfer foil was prepared in the same manner as in Example 1 except that the heat pressing process with a heated rubber roll was not performed.

<Comparative example 2>
A transfer foil was prepared in the same manner as in Example 1 except that the polystyrene spherical transparent particles were excluded from the optical effect layer coating solution composition, and the heat pressing treatment with a heated rubber roll was not performed.

The transfer foil prepared as described above was transferred to a cloth medium (polyester satin) to obtain an anti-counterfeit article. The appearance and bendability were evaluated visually.
Compared with the case of using the transfer foil of Comparative Example 2, when the transfer foil of the present invention of Example 1 is used, the reflection of external light by the outermost surface of the transparent portion without the reflective layer becomes inconspicuous and there is no glare.

Compared with the case of using the transfer foil of Comparative Example 1, when the transfer foil of the present invention of Example 1 is used, the reflection of external light by the outermost surface of the transparent portion without the reflective layer becomes inconspicuous and there is no glare. Appeared.

  As described above, the transfer foil of the present invention is formed by coating and forming a coating liquid containing particles on the release layer, and then pressing the roller with a roller so that the shape of the particles (unevenness) is raised on the release layer side. When the surface is transferred to the article, unevenness is generated on the exposed surface, so that scattering of the reflected external light is increased and the shine is reduced.

  Moreover, since the particles of the optical effect layer are separated from each other in the transfer foil of the present invention, the strength can be maintained even when transferred to a highly stretchable substrate, and the metal foil formed on the particles does not crack. Therefore, it can be said that it is a transfer foil particularly suitable for transfer to a cloth from the viewpoint that cracks in the reflective layer are not noticeable.

  The present invention is suitable as a transfer foil to be transferred to an article, and particularly suitable for an object to be transferred having a rough surface such as cloth, but it can be used for anti-counterfeiting and authenticity determination, and further enhances the design effect. It can be widely used for a transfer medium that can utilize the above.
