Abstract

PURPOSE:To improve the decorativity and the forgery preventing ability by laminating successively a reflecting thin film layer, a hologram layer and a pattern layer on a card substrate through an adhesive layer. CONSTITUTION:A hologram transfer sheet with a pattern in which the pattern and hologram are constituted in a single body, is formed by the constitution to laminate successively a separating protecting layer 7, a pattern layer 6, a hologram layer, a reflecting thin film layer 3 and an adhesive layer 2 on a supporting body. The pattern layer 6 uses the ink considering the covering characteristic to the hologram and is formed by the suitable ink thickness on the separating protecting layer 7. The separating protecting layer 7 protests the pattern layer 6 and the hologram layer 5 after transferring. By heating applying or applying by using the hologram transfer sheet with the pattern, the hologram having the pattern on the surface of the hologram layer 5 is formed on a card substrate 1. Thus, the decorativity and the forgery preventing ability of the card are improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hologram card with a picture, which is provided with a hologram having a picture on its surface in a position visible from the outside.

(Prior Art) A hologram reproduces a three-dimensional image by using the wavefront of light from an object as a light interference fringe. Since such holograms require advanced technology to manufacture, they are often placed on some cards such as credit cards and bank cards as a means of preventing counterfeiting, and on books such as magazines and books for the novelty of their appearance. Attempts have been made to provide them on covers, pamphlets, calendars, record jackets, paper and plastic packages, clothing, etc.

In many cases, holograms are made of a colorless and transparent synthetic resin film with fine irregularities formed by embossing and a light-reflecting metal layer as a light-reflecting layer. The color of the entire hologram is determined by the light-reflecting metal layer, and since aluminum is normally used as the light-reflecting metal layer, it is limited to silver-gray, so depending on where it is used, the surrounding pattern may have a large design There were many restrictions.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned conventional drawbacks. That is, the card has a pattern on its surface that matches the design of the card and is in sync with the hologram. Decorativeness and counterfeiting 1

The I'9 value of this card base material is preferably 01 to 3N.

The adhesive layer 2 serves to adhere the reflective thin film layer 3 to the card base material h. As the heat-sensitive adhesive used for the adhesive layer, a wide range of those known for conventional adhesive layers such as acrylic resin, vinyl resin, polyester resin, urethane resin, amide resin, and Epoquin resin can be used. . Furthermore, as the adhesive, a wide variety of common adhesives such as acrylic and rubber adhesives can be used. The thickness of this adhesive layer is preferably 01 to 50 μm, preferably 05 to 20 μm.

The reflective thin film layer 3 provides reflective properties to the hologram layer 5, and is made of Cr, Fe, Co, Ni, Cu, A

It is formed using metals such as In%Ga and rtb, their oxides, nitrides, etc. alone or in combination of two or more. Among these metals, A1, Cr, Ni, A
g, Au, etc. are particularly preferred.

The reflective thin film layer 3 can be formed by methods such as vapor deposition, sputtering, ion blating, CVD, or plating, and preferably has a thickness of 200 to 1000 Å.

Alternatively, even if a continuous thin film of a substance having a refractive index different from that of the hologram layer 5 is provided in addition to the above-mentioned thin film of metal, gold oxide, or metal nitride alone or in combination, such a film itself Although it is clear, it can be used as a reflective thin film layer.

The continuous thin film preferably has a refractive index greater than the refractive index of the hologram layer 5 by 03 or more, more preferably by 05 or more. According to the experiments of the present interstitium, it has been concluded that 10-F or more people's hearing increases the most.

It may be any transparent region of the material forming the continuous thin film with a 1 degree angle of 1177 degrees, but usually 100 to 10.00 OA is preferable. As a method for forming the continuous thin hologram layer 5 on the reliso forming surface, that is, the hologram forming portion 4, general thin film forming means such as a private chamber vapor deposition method, a sputtering method, and an ion blasting method can be employed.

When a continuous thin film with a high refractive index is provided in this way, it is a characteristic of holograms.Due to the angular dependence of the hologram, outside the ilfl regeneration angle range of the hologram, it can only be formed as a transparent body of jJ%, and the hologram's 1+1 Within the range of possible angles, the light reflectance is at its maximum, producing the effect of a reflective hologram.

Even with the reflective metal thin film layer mentioned above, the thickness is 200 mm.
If it is less than A, the refractive index is the complex refractive index n''(n' =

Further, a transparent synthetic resin layer having a different refractive index from that of the 5 hologram layer 5 can be substituted for the reflective thin film layer 3, and specific synthetic resins that can be used are as follows.

Polytetrafluoroethylene (refractive index; n = 135), polychlorotrifluoroethylene (mouth = L43), polyvinyl acetate (n = 1.45 to 1°47), polyethylene (low 150 to 1.54), polypropylene ( n = 1.4

．． 48), polyvinyl formal (rho 1.50), polyvinyl chloride (n=1.52-155), polyester (n=1.52-157).

On one side of the hologram layer 5, that is, on the side IJ-, there is provided a hologram forming portion 4 in which minute irregularities are formed. This minute unevenness shape produces a hologram by the reproduction light, and in order to change the visual effect depending on the reproduction position of the hologram, the imaging and focal position during hologram shooting are set to be in front of the embossed surface when the hologram is reproduced. , or set the pitch and uneven height difference so that the image is formed on the rear side 1H to 6M. In reality, the pitch is 01 to 20 μm and the height difference between the unevenness is 001 to 1 μm. As will be described later, the minute unevenness shape is a reverse shape of the minute unevenness shape of the mold surface of the hologram master created in advance, which is formed by hot pressing or the like.

The hologram layer 5 is transparent or colored to be translucent to such an extent that the hologram can be seen through. Note that the hologram master plate may also be divided and colored into each color.

The hologram layer 5 is preferably colored with a dye or a pigment, and examples of usable dyes include the following various dyes.

Direct dyes, acid dyes, basic dyes, mordant dyes, vat dyes, sulfur dyes, soluble vat dyes, azoic dyes, reactive dyes, cationic dyes, disperse dyes, oxidation dyes, metal complex dyes, etc.

The dye used here causes the colored hologram layer 5 to be exposed to light twice, so that the light enters the colored hologram layer 5, is reflected on the surface of the reflective thin film layer 3, and is emitted again. is transmitted through the colored hologram layer 5.
It is desirable that the light transmittance of the layer 5 is not significantly reduced and that the layer 5 is not cloudy. Since the light transmittance varies depending on the thickness of the layer 5, it is preferable that the white light transmittance of the layer 5 is 50% or more, and the haze value measured by an ismeter is preferably 10% or less. If the white light transmittance is less than 50%, the hologram will not look clear and the three-dimensional effect will be poor, and if the haze value measured by the ismeter exceeds 10 inches, a milky white haze will appear in the background of the hologram, which will also affect the color of the hologram. The brightness is lost, and the physical sensation becomes poor.

In addition, the properties required of the dye include the material of the hologram layer 5 to be colored, the forming blade of the layer 5, and the durability with respect to the processing performed on the layer 5. For example, when forming layer 5 using an ultraviolet curable resin,
1 After embossing the minute unevenness shape of the grat forming part 4, it is equivalent to 1
In order to irradiate with Tsuji's purple rays, it is preferable to use ultraviolet rays that do not discolor or discolor when irradiated with UV rays (1). It is preferable to use dyes that cause little color or discoloration.

Moreover, since it is used for cards, it is preferable to use a dye that takes into consideration various physical properties such as chemical resistance, solvent resistance, plasticizer resistance, and f)t; Y4 fastness.

Taking into account various practical conditions such as L, the dye is preferably in the form of a soluble metal complex, for example:
Examples include type 1-2 azo metal complex dyes, type 1-1 azo metal complex dyes, metal phthalonanine dyes, and organic base salts of these dyes, and more specifically, the following. .

Paris First Yellow +3104 and ≠31 (1

Furthermore, pigments used for coloring the hologram layer 5 are broadly classified into organic pigments and inorganic pigments. Organic pigments include: (1) Neutral pigments, such as nitro pigments, azo pigments, anthraquinone pigments, phthalonanine pigments, azine pigments, etc.; (2) Cationic pigments, such as trifluorocarbon pigments. Phenylmethane pigments, xanthene pigments, etc. (3) Anionic pigments, such as azo pigments and triphenylmethane pigments, and inorganic pigments such as cobalt pigments and iron pigments. Pigments include chromium-based pigments, manganese-based pigments, copper-based pigments, vanadium-based pigments, mercury-based pigments, lead-based pigments, sulfide-based pigments, and selenide-based pigments.

Regarding the above pigments, W,
It is necessary to pay attention to various properties such as transmittance, haze value, ultraviolet rays, discoloration upon exposure to electron beams or heating, chemical resistance, plasticizer resistance, and washing fastness.

In particular, when using pigments, translucency is generally a problem, and it is necessary to consider the diameter of the ladle of the pigment, wetting with the surrounding synthetic resin, and dispersion. If the dispersion is poor, cloudiness will occur. In this sense, the particle size of the pigment is very small, preferably 1/2 or less of the wavelength of light, and the pigment is added to a synthetic resin at a high concentration by coprecipitation, roll milling, nixtrusing, etc. It is preferable to use masterbatches, master pellets, etc., which are dispersed in water and have improved wetting and dispersion. Examples of pigments with improved wetting and dispersion include:
For example, Nokotrans Yellow (BAS) manufactured by Taisei Kajosha
Finely ladle iron oxide (long axis 0.06 μm, short axis (1,02
Nitrified cotton chipped pigment of ltn.) and [11-Chip 4 ((nitrated cotton chipped pigment of insoluble gel azo yarn dye) manufactured by Taisei Ka I111).
