CONSTITUTION:A plastic film is used as a substrate 1, thereon a releasable layer 2 and a color layer 3 are successively provided using suitable resins, thereon an insulating metal layer 4 is provided by forming a checkered structure metallized layer using Sn etc., and thereon an adhesive layer 5 is formed using a suitable resin to form a transfer foil for copying. By using this transfer foil for copying, a toner 6 is applied on the adhesive layer 5 in desired characters and patterns by copying. Thereafter, the surface with the toner 6 applied is contact overlapped with a target transfer body 7, such as copying papers, desired papers, leathers, and plastics, and heated and pressurized by a heat roll etc. A substrate 1 is peeled, whereby on the transfer body 7 the toner 6 and only the corresponding parts of the adhesive layer 5, the insulating metal layer 4, the color layer 3, and the releasable layer 2 are transferred, and the transferred part has characters and patterns.

Description

[Detailed description of the invention] (Industrial application field) This invention relates to a transfer foil for copying.

(Prior Art) Conventionally, as a transfer method to copy paper, toner is attached to desired characters and patterns on copy paper by copying, and a base material, a release layer, a color layer, a metal layer, and an adhesive layer are applied from above the toner. The adhesive layer, metal layer, color layer, and release layer of the transfer foil are transferred and formed only on the toner by heating and pressing the transfer foil in which the adhesive layer surfaces are brought into contact and then peeling off the base material. , produced copy paper with metallic luster letters and patterns.

This method is widely used, mainly by designers, because it is extremely easy to create the desired color and pattern design, and it also provides a metallic luster such as gold or silver.

(Problem to be solved by the invention) However, in the conventional method, the type, size, thickness, etc. of paper on which desired characters and patterns can be designed is limited to copy paper, and other desired papers, leather, There has been a drawback in that metallic luster characters and patterns cannot be easily obtained on various transfer materials such as plastics because they cannot be copied.

In order to solve this problem, it is possible to apply toner on the transfer foil in advance and transfer it onto copy paper or the desired paper, leather, plastic, etc., but in this case, the following method may be used. There is a problem.

That is, since the toner is copied directly onto the transfer foil, the toner may not adhere at all or may not adhere properly. This is because the transfer foil needs to be passed directly through the copy machine.
This is how it works due to the principle of copying. The principle of copying is: ■ The metal substrate (photosensitive drum) inside the copy machine is made conductive and charged. ■ When the image is focused on the substrate through a lens, the areas exposed to light tend to conduct electricity. This means that the charge is lost, and the toner adheres only to charged areas and does not adhere to other areas.If the material to be copied, for example transfer foil, is conductive, there may be areas that are not exposed to light. The charge is lost and toner no longer adheres to the photosensitive drum. Therefore, toner does not adhere to a transfer foil having a metal layer because the metal layer has conductivity.

This invention eliminates the above-mentioned various drawbacks, and is a copying transfer foil that makes it possible to copy onto a transfer foil and transfer it onto copy paper or a desired transfer material such as paper, leather, plastic, etc. It provides:

(Means for solving the i!If! problem) The present invention provides a transfer foil comprising a base material, a release layer, a color layer, an insulating metal layer, and an adhesive layer, which are laminated in this order. Apply toner on the desired characters and patterns by copying, and then apply the toner and the corresponding adhesive layer, insulating metal layer, color layer, and release layer to the copy paper or desired paper, leather, or plastic. This is a copying transfer foil for transferring onto objects such as.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram of the cross-sectional structure of the copying transfer foil of the present invention and the process of using it. Further, FIG. 2 shows a conventional method and a transfer foil used therein.

In this invention, the transfer foil has an insulating metal layer instead of an electrically conductive one. Specifically, for example, Japanese Patent Application Laid-Open No. 62-174
As described in Japanese Patent No. 189, the transfer foil has a metal vapor deposited layer having an insulating property as an island structure. That is, a plastic film is used as the base material 1, a release layer 2 and a color layer 5 are sequentially provided on the base material 1 using a suitable resin, and a metal vapor deposition layer with an island-like structure is further formed using Sn or the like on top of this to provide insulation. The transfer foil for copying was prepared by providing a metal layer 4 with a transparent coating, and then providing an adhesive layer 5 thereon with an appropriate resin.

In this case, if the color layer 5 is left uncolored, the color of the insulating metal layer 4 (silver color in the case of Sn) will appear as is, and such a layer is also included in the present invention. Furthermore, one layer may serve as both the release layer 2 and the color layer 3, and such a layer is also included in the present invention. Note that the insulating gold i-layer 4 may be made by adding metal powder or the like in a certain amount or less to make it insulating even though it has metallic luster; Included in this invention.

The transfer foil for copying as described above is used to adhere toner 6 onto the adhesive layer 5 in desired characters and patterns by copying. Next, the surface to which the toner 6 is attached is used as a transfer target 7 such as copy paper or desired paper, leather, plastic, etc.
The base material 1 is polymerized by contact polymerization, heated and pressed using a hot roll, and then the base material 1 is peeled off.

In this way, the toner 6 and the adhesive layer 5 corresponding to the toner 6, the insulating metal layer 4, the color layer 3, and The peeling layer 2 is formed by transfer, and the portion thereof has metallic luster letters and patterns.

(Example) A transparent long polyester film with a thickness of 75 μm was used as a base material, and a wax-based resin was coated on one side of the film using a gravure coater and then dried to form a release layer. Next, a rosin resin and a urea-melamine copolymer resin are applied and dried using a gravure coater to form an uncolored color layer, and then a Sn vapor deposition layer with an island-like structure is formed by vacuum vapor deposition to form an insulating metal layer. formed a layer. Next, an acrylic resin and titanium oxide were coated and dried using a reverse coater to form an adhesive layer to obtain a copying transfer foil of the present invention.

Next, this transfer foil for copying was passed through a copying machine, and toner was applied to predetermined characters on the adhesive layer. After that, this was applied to copy paper, postcards, embossed paper, art paper, leather, and plastic as transfer objects, and the toner-adhered surfaces were brought into contact with each other, heated and pressed with a hot roll, and then the base materials were peeled off. The toner and only the corresponding parts of the adhesive layer, insulating metal layer, color layer, and release layer were transferred onto the transfer object, and beautiful silver-colored letters were obtained in all cases.

(Effects of the Invention) Since this invention has the above-mentioned advantages, whereas in the past, copying transfer foil could only be transferred to copy paper,
According to the present invention, beautiful metallic luster characters and patterns can be transferred not only to copy paper but also to various desired transfer materials such as paper, leather, plastic, etc.

In this invention, toner can be freely attached to desired characters and patterns on the adhesive layer of the transfer foil for copying, and then this can be used to easily transfer to various types of transfer objects.
