Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention has a conventional printed pattern on a hologram. This invention relates to a hologram transfer sheet that has an appearance suited to its intended use and has excellent decorative properties and anti-counterfeiting properties.

(Prior art) Holograms can reproduce three-dimensional images using light interference, and because they require advanced technology to manufacture, they are used as a means of preventing counterfeiting in cash vouchers such as credit cards and certificates. , placed on a part of a certificate, etc., or on the cover of a book, pamphlet, record label, etc. to give it a novel appearance.

Attempts have been made to include it in packages, clothing, etc.

In many cases, holograms are made by using a colorless and transparent synthetic resin film with minute irregularities formed by embossing, and a light-reflecting metal layer as a light-reflecting layer. The light-reflecting metal layer, usually aluminum, limits the overall color to a silver-gray color, which often does not match the surrounding design depending on where it is used.

Furthermore, in order to add a pattern to the hologram that should match the surrounding design, it is necessary to transfer the hologram to the layered material and then apply the pattern on the hologram by printing, etc.
However, depending on the form of the adherend, this may be technically impossible. Even if it were possible, processing into such a hologram would be difficult and unsuitable for mass production, and the design would be printed on top of the transferred hologram.

The pattern, hologram design, and nine color tones were difficult to harmonize with, giving it a foreign feel.

(Problems to be Solved by the Invention) Therefore, the present invention is capable of mass reproduction using an embossed type, and also has a hologram according to the purpose and an appropriate pattern that harmonizes with the hologram, and has a pattern corresponding to the part to be used. We use highly decorative and anti-counterfeit patterned holograms that match the surrounding designs for various products, especially as needed.
To provide a hologram transfer sheet with a pattern that can be mass-produced and easily adhered to cards, certificates, securities, certification documents, etc.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned points, and the patterned hologram transfer radiation thin film layer and the contact layer according to the present invention are sequentially laminated as a transfer layer. The patterned hologram transfer sheet is characterized in that the pattern printing layer comprises a normal printed pattern covering at least a part of the translucent layer.

The present invention will now be described in more detail with reference to the accompanying drawings, which schematically illustrate preferred embodiments of the patterned hologram transfer sheet of the present invention.

The embodiment diagrammatically shown in FIG. 1 shows the basic structure of the patterned transfer cartridge A of the present invention, in which a pattern printing layer 3 is formed on a peelable protective layer 2 provided on a support 1. The hologram is formed with a normal printed pattern that covers at least a portion of the transparent edge, and is colored transparent or semi-transparent to the extent that the hologram can be recognized as necessary, or colored so as to completely hide the hologram. There is.

This support 1 supports other layers, layers 2 to 7 in the example of FIG. As long as the sheet-like material has surface properties that can be coated, appropriate strength, and heat resistance.

Any known material may be used, such as plastic or film such as polyethylene terephthalate, polypropylene, polyethylene, polyamide, etc. The thickness of the support 1 is not particularly limited as long as it has appropriate strength and heat resistance, but a thickness of about 5 to 250 microns is used.

The peelable protective layer 2 protects the hologram layer after transfer, and also protects the support 1, pattern printing layer 3, and light-transmitting layer 4 during transfer.
This improves the peeling of the product. Of course, both a protective layer and a release layer may be provided.

Such a peelable protective layer 2 is coated on the support with a thickness of 0.05 to 10 μm, preferably 0.1 to 10 μm.
It is provided with a thickness of 5 μm. If the material used for these peeling protective layers 2 is sufficiently translucent, it may have wear resistance or
Select and use in consideration of performance such as stain resistance and solvent resistance.

For example, single substances, mixtures, and copolymers of cellulose resins, (meth)acrylate resins, vinyl chloride resins, vinyl acetate resins, urethane resins, melamine resins, and polyester resins are used.

The pattern printing layer 3 is printed on the removable protective layer 2 by a known printing method such as a gravure printing method, a silk screen printing method, an offset printing method, an electrostatic printing method, a letterpress printing method, or a jet printing method. The printed pattern can be any normal printing pattern, for example, on the hologram surface, ■
Patterns printed all over the entire surface (uniform layer on the negative side), ■Patterns printed partially solid, ■Patterns printed all over or partially on a solid surface with white gaps, ■Logos, numbers, symbols, Background patterns, marks, etc. are used.

Furthermore, the pattern to be printed can be determined by the type of ink used.The ink used here may be appropriately selected according to the printing method. , plasticizers, stabilizers, other additives, solvents or diluents are used.

Preferably, electron beam and ultraviolet curing type methacrylic resins, acrylic resins, rosin-modified phenol resins, alkyd resins, epoxy resins, urethane resins, and the like are used.

Furthermore, the coloring of the ink is carried out using general pigments or dyes, but in consideration of transparency and hiding properties, pigments with high hiding properties are mainly used. *Preferably, the particle size of the ink is within the wavelength of visible light. It is better to use particles that are larger than the half wavelength of the particle and have a large difference in refractive index between the binder and the particles. For example, titanium white, yellow lead, Brilliant Carmiso 5B, carbon black, Lake Red C1, etc., which have relatively large particle sizes, are used. In addition, in order to obtain transparency, dyes and pigments are used, preferably those whose particle size is smaller than half the wavelength of visible light and whose refractive index difference between the binder and the particles is small. For example, as a dye, 1-2
Type azo metal complex dye, 1-1 type azo metal complex dye,
Metal phthalonaniline dyes and f-salts, organic salts of these dyes, are used. As a pigment,
Nitrified cotton chipped pigment made of fine particles of iron oxide, nitrated cotton chipped pigment made of insoluble azo dye, Victoria Blue Lake, etc. can be used. By using these inks and using an appropriate printing method, a normal pattern is printed on the removable protective layer 2, if necessary, with a concealed, translucent, or transparent color at an ink coating thickness of 0.
The thickness is 1 to 20 μm, preferably 0.5 to 5 μm.

A light-transmitting layer 4 having minute unevenness 5 is formed on the pattern printing layer 3 .

Part'y"fM"I,'Since the light is emitted in a reverse direction on the surface of the spectrally reflective metal layer and is emitted again, it is preferable that the light be on a colored hologram, and the haze value measured by a haze meter is The content is preferably 10% or less. White light transmittance is 50%
If it is less than 10 inches, the hologram will not look clear and the three-dimensional effect will be poor, and if the haze value exceeds 10 inches, the background of the hologram will become milky white, and the sharpness of the hologram will be lost, and the three-dimensional effect will be poor. I feel less.

When forming a hologram using a micro-irregular shape, a considerable amount of ultraviolet rays are irradiated after forming the hologram into a microscopic uneven shape, so it is preferable to use a material that does not change color or fade when exposed to ultraviolet rays, and an electron beam curable resin is used to form the counterfeit. In some cases, it is preferable to use a dye that is less likely to fade or change color when irradiated with an electron beam.

Also, depending on the purpose of the color viewing hologram transfer cartridge, for example, if it is applied to cards, clothing, stationery, etc., it must be chemical resistant and solvent resistant.

In particular, when using pigments, translucency is generally a problem, and it is necessary to consider the particle size of the pigment, wetting with the surrounding synthetic resin, and dispersion. If the color decreases, it becomes cloudy, and if the dispersion is poor, it will become cloudy. 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 can be highly concentrated in a synthetic resin by coprecipitation, roll milling, extrusion, etc. It is preferable to use master batches, master pellets, etc. that have improved dispersion, wetting, and dispersion.

On one side of the light-transmitting layer 4, a hologram minute unevenness shape 5 is formed.
is formed. This fine unevenness shape 5 is used to reproduce the hologram using reproduction light.In order to change the visual effect depending on the reproduction position of the hologram, the imaging and focal position during hologram photography are set to the front of the embossed surface when the hologram is reproduced. , or the pitch and height difference of the unevenness are set so that the image is formed on the rear side 12aI to 6m.

In reality, the pitch is 0.1 to 20 μm, and the height difference between the unevenness.

It is 0.01 to 1 μm. As will be described later, the minute unevenness shape 5 is a reverse shape of the minute unevenness shape of the mold surface of the hologram master created in advance, and is formed by hot pressing or the like.

A light-reflecting thin film layer 6 is laminated on the surface on which the micro-asperities 5 are formed.

It is formed using metals such as Ga, t'Lb, and their oxides, nitrides, etc. alone or in combination of two or more. Among these metals, AI, Cr, Ni, Ag
, Au, etc. are particularly preferred.

The reflective thin film layer 6 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 forming layer 4 is provided in addition to the above thin film of metal, metal oxide, or metal nitride alone or in combination, such a film itself Although it is transparent, it can be used as a reflective thin film layer.

As a method for forming a continuous thin film on the relief forming surface of the hologram forming layer, general thin film forming means such as vacuum evaporation, sputtering, reactive sputtering, and ion blating can be employed.

When a continuous thin film with a high refractive index is provided in this way, due to the angular dependence of reproduction, which is a characteristic of holograms, it appears as a mere transparent body outside the angular range where the hologram can be reproduced; In this case, the light reflectance becomes maximum and the effect as a single-reflection hologram appears.

The continuous thin film described above may have a refractive index smaller than that of the hologram forming layer, such as LiF (n=1.4), Mg
