Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hologram transfer foil and a hologram sheet material, and more specifically, to provide various printed matters such as labels and cards having excellent design.

[0002]

2. Description of the Related Art Conventionally, various labels and cards have been increasingly required to have excellent aesthetics and design. For example, various labels such as glass containers for various beverages such as beer, containers such as metal cans and plastic bottles, containers for various food products, containers for various cosmetics, etc. Along with feeling, excellent aesthetics and design are required.

A prepaid card for use in subways, trains, buses, etc., which is one of the cards,
Highway cards, telephone cards and other prepaid cards are widely used.

In order to enhance the design and decoration of the above labels, cards, and other printed matters, for example, in the case of cards, holograms (in the present invention, "holograms" are various diffraction gratings). Is used to mean that
Incorporation is done so that the image is visible from the surface. The hologram transfer foil is most advantageous in the process for incorporating the hologram. Such a hologram transfer foil is one in which an OP layer (protective layer), a hologram forming layer, a hologram effect layer, and an adhesive layer are laminated on the surface of a base material film via a release layer (release layer).

[0005]

[Problems to be Solved by the Invention] By using the above hologram transfer foil, labels, cards, and other materials to be transferred,
When the transfer layer including the hologram layer is transferred, the peeling layer is located on the outermost surface of the transfer layer after the transfer. Since the release layer contains a release agent, it is difficult to print various patterns on the surface of the release layer. Further, when a transfer layer including a hologram layer was transferred with a hologram transfer foil having a release layer instead of the release layer, the OP layer became the outermost surface, but the release agent remained on the surface of the OP layer. Similarly, good printing cannot be performed on the surface of the OP layer. Therefore,
An object of the present invention is to provide a hologram transfer foil and a hologram sheet material using the transfer foil, in which a hologram sheet material having a hologram image and a printed pattern aligned can be obtained without printing on the OP layer. .

[0006]

The above object can be achieved by the present invention described below. That is, in the present invention, a release layer or a release layer, a printing layer, a hologram forming layer, a hologram effect layer and an adhesive layer are laminated in this order on a substrate film, and a printed pattern of the printing layer and a hologram image. There is provided a hologram transfer foil, which is characterized by matching with, and an original hologram sheet fabric using the transfer foil.
An OP layer may be provided between the print layer and the peeling layer. Further, in the present invention, the “raw material” means a sheet before being cut into a label, a card, or the like.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the following preferred embodiments. As shown in FIG. 1, the hologram transfer foil 100 of the present invention has a release layer or release layer 2, a printing layer 3, a release layer or a release layer 2 on a base film 1 as shown in FIG.
The anchor layer 4, the hologram forming layer 5, the hologram effect layer 6, and the adhesive layer 7 are laminated in this order, and the printed pattern of the printed layer 3 and the hologram image are matched. An OP layer may be provided between the peeling layer 2 and the printing layer 3. The anchor layer 4 is not essential, but it is preferable to provide it in order to improve the formation of the hologram forming layer 5.

Base film 1 for hologram transfer foil 100
Is usually a transparent or opaque polyethylene terephthalate film or a polyethylene naphthalate film having a thickness of about 12 to 100 μm.

The release layer (release layer) 2 is made of an acrylic resin containing a suitable release agent, if necessary, and has a thickness of about 0.5-.
The thickness is about 4 μm. The OP layer, which is provided if necessary, is formed from a solution of polyester resin, acrylic resin, or the like to a thickness of about 0.2 to 1.0 μm.

The printing layer may be formed by any printing method, but in the case of offset printing, it is difficult to accurately match (register) with a hologram image, which will be described later. Gravure printing or silk printing is preferable, and particularly by using gravure printing, the consistency between the printed pattern and the hologram image is improved.

The printing ink used above may be a conventionally known printing ink. When the printing ink is a colored transparent ink, the hologram image is not hidden after the hologram layer is transferred, but the printed pattern and the hologram image can be matched to each other in order to exhibit a better design. preferable.

When the printing ink is an opaque ink, the hologram image is hidden after the hologram layer is transferred. Therefore, the printed pattern and the hologram image can be aligned so as not to hide the hologram image. is necessary. Specifically, when the printed pattern is opaque, the printed pattern is 10 to 90% of the area of the hologram image.
It is preferable to set it as the range.

As described above, when forming a print pattern,
Since the release agent and the like are not present in the printing base, the printing is performed well, and there is no inconvenience in printing after transferring the hologram layer as in the conventional technique. The anchor layer 4 is formed, for example, from an ultraviolet curable resin such as urethane acrylate or epoxy acrylate or a resin such as vinyl chloride / vinyl acetate copolymer to a thickness of about 1 to 4 μm.

The hologram forming layer is preferably formed of an ultraviolet curable or electron beam curable resin to a thickness of about 1 to 10 μm, and the uneven shape (diffraction grating) of the hologram is formed on the surface by embossing using a master plate. , Then completely cure. The hologram effect layer 5 has a thickness of about 100 to 2,0 by vapor deposition of aluminum (reflection hologram), sputtering of metal oxide (transparent hologram), or the like.
Form to about 00Å. It should be noted that color printing, which becomes the background of the hologram image, may be provided below the transparent hologram effect layer.

The adhesive used for the hologram transfer foil may be any of the conventionally known heat-sensitive materials such as acrylic resin, polyethylene resin, ethylene / vinyl acetate copolymer resin, vinyl chloride / vinyl acetate copolymer resin, polyester resin and polyamide resin. Adhesives and dry laminate adhesives can also be used.

Examples of the dry laminate adhesive include a two-component curing type urethane type adhesive, an epoxy type adhesive, an ultraviolet ray or electron beam curing type adhesive, which is used by mixing polyisocyanate, polyol and a catalyst immediately before use. Use is desirable. When using a two-component curing type adhesive such as a urethane type, A according to the prescription determined immediately before use
The liquid, the liquid B and the catalyst are mixed to form a thickness of about 1 to 10 μm, and the hologram layer is transferred from the hologram transfer foil to the transfer target material using a laminator within a predetermined time to transfer the hologram layer. When an ultraviolet ray or electron beam curable adhesive is used, the adhesive is cured using ultraviolet rays or an electron beam after the adhesion and is then adhered.

The hologram transfer foil of the present invention having the above layer structure is the same as that of the prior art except for the structure of the printing layer,
The manufacturing method is also the same. The hologram transfer foil of the present invention as described above is useful for transferring onto various materials such as various labels and cards, and various original materials excellent in designability, and further labels and cards obtained by cutting the original materials. Can be obtained.

Next, the original hologram sheet obtained by using the hologram transfer foil of the present invention will be described. The material to be transferred is not particularly limited, and examples thereof include paper, synthetic paper, a plastic film or sheet, a raw material of a label raw paper or a raw material of a card base material.

The original hologram sheet 200 of the present invention is
As shown in FIG. 2, when the hologram layer of the hologram transfer foil of the present invention is transferred to one surface of the transferred material 8 and the base film 1 is peeled off, the hologram layer does not have an OP layer. Is on the surface of the printing layer 3 which is the outermost surface (when a release layer is formed instead of the release layer), or when the hologram transfer foil has a release layer, the release layer which is the outermost surface. It is obtained by forming an OP layer 9 (protective layer) on the surface. When the hologram layer has an OP layer, the formation of the OP layer is not essential.

The OP layer formed after the above transfer is a surface protective layer, and is made of polyester resin containing a lubricant such as wax, acrylic resin, ultraviolet ray or electron beam curable so as to give abrasion resistance and other physical strength. A clear coating of resin is applied, dried or cured to a thickness of 0.2-1.
The thickness is about 0 μm. In the illustrated embodiment, the release layer 2 is also transferred together with the hologram layer. On the other hand, when the hologram transfer foil 100 has the release layer 2, the release layer 2 is released at the interface between the release layer 2 and the printing layer 3 during transfer, and the release layer 2 is not transferred to the side of the original sheet 200.

In the production of the above-mentioned original fabric 200, a heat-sensitive adhesive, a pressure-sensitive adhesive, a dry laminate type adhesive or other adhesive can be used as the adhesive layer 7 used for the hologram transfer foil 100. When is a material that is adversely affected by heat, for example, a base material for a thermal recording card, it is preferable to use an adhesive that does not require heating for adhesion, for example, a pressure sensitive adhesive or a dry laminate type adhesive. For example, when transfer is performed with a hologram transfer foil using a heat-sensitive adhesive such as a heat-sealing agent, the heat-sensitive recording layer of the original fabric of the card base material may be colored by heating.
However, a heat-sensitive adhesive can be used when there is no problem of heat in bonding such as a label or other printed matter.

The hologram transfer foil 100 is transferred onto the transfer material 8 by, for example, transferring the transfer layer including the hologram layer to the transfer material 8 by the adhesive layer when the adhesive layer 7 is formed of a dry laminate type adhesive. After the adhesive layer is cross-linked and cured to complete the adhesion, the substrate film on the hologram transfer foil side is peeled off. Then, if necessary, the OP
Form the layer 9.

In a preferred embodiment of the present invention, the hologram effect layer 6 in the hologram-containing layer transferred to the material 8 to be transferred is a reflective metal thin film such as an aluminum vapor deposition layer, a metal oxide, or the like. It may be a transparent layer having a refractive index different from the refractive index of the hologram forming layer such as the synthetic resin. When the hologram effect layer is reflective, a highly reflective hologram image is observed, while when the hologram effect layer is transparent, a hologram image whose background is a color based on the hue of the transferred material. When a pattern layer (not shown) is formed between the transparent hologram effect layer and the material to be transferred, a hologram image mixed with the pattern is observed.

Next, as one embodiment of the present invention, a case where the transfer material is a raw material for a thermal recording card will be described. The raw material for a thermal recording card of the present example has a pressure-sensitive adhesive layer on the other side of the white base material of the card base material having at least a magnetic coating layer and a thermal recording layer on one side of the white base material. At least through the printing layer, hologram effect layer,
The transfer layer including the hologram forming layer and the OP layer is transferred. In addition, in the present invention, "a raw material of a card base material" means that a standard size finished card is 2 to 8 vertically and 4 to 10 horizontally.
It means a raw material of a card substrate having a size capable of punching out a total of 8 to 80 sheets.

According to the above-described embodiments, the transfer layer including the hologram layer can be continuously transferred to the original material of the card substrate, which is very economical. When individual cards are created, the number of completed cards is limited because individual cards are required to be used for different purposes, for different companies, and assorted with various designs. Therefore, since individual cards can be created by subdividing the serially mass-produced original sheets, it is very efficient as a whole as compared with the method of transferring the hologram layer for each individual card.

The above description is for the case where a thermal recording card substrate is used as a typical example of the material to be transferred, but the material to be transferred in the present invention is not limited to the above-mentioned embodiment, and is described in the section of the prior art. Further, it may be a label for various containers, a base material for various cards, or a base material for other printed matter. For example, the present invention is also useful for label substrates to be attached to containers for beverages, foods, cosmetics and the like, and other printed matter substrates that require high-grade feeling and excellent designability.
