Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a transfer sheet used for so-called instant lettering and a thermal transfer ribbon used in the method.

[0002]

2. Description of the Related Art The technique of instant lettering has been known for a long time, and in the past, a transfer sheet was formed by printing a reversal image such as letters and designs on a releasable support with pressure-sensitive or heat-sensitive ink. The image was formed on the object by superposing this transfer sheet on the object on the image side and rubbing it with the finger from the back side of the transfer sheet or by heating it with an iron. .

However, in this conventional method, since the image to be transferred is formed by printing, it is not suitable for small-lot production of a wide variety of products, it cannot be created immediately when necessary, and an image pattern cannot be easily obtained (image pattern There is a problem such as a great deal of time, labor, and cost are required to create the printing plate.

With the recent development of word processors, it has become possible to produce the transfer sheet by thermal transfer by a word processor equipped with a thermal transfer printer instead of by printing (for example, Japanese Patent Laid-Open No. 63-128990, 63).
-128987, 63-130388, etc.), which enables high-mix low-volume production, immediate creation, and easy creation of image patterns.

However, the method for producing a transfer sheet by this thermal transfer still has the following problems.

One of them is that it is necessary to prepare a special material as a support (printing target) of the transfer sheet. That is, in order to retransfer an image formed by thermal transfer on the support to a target object, it is necessary to use a support which has been subjected to a release treatment so that the image is easily peeled off.

Since a relatively thick support (for example, about 100 μm) is used as the release-treated support, a transfer sheet is used when the target object has a complicated curved surface. Cannot be made to follow the surface, and transfer is difficult, and when the target surface to be targeted is the inner surface of a narrow space, transfer work is difficult.

In view of the above points, an object of the present invention is a method of preparing a transfer sheet by thermal transfer, which allows the transfer sheet to be prepared without using a support which has been subjected to a special treatment such as a mold release treatment, which is more complicated. It is an object of the present invention to provide a method for producing a transfer sheet that can be transferred onto a curved surface or the inner surface of a narrow space, and a thermal transfer ribbon used for the method.

FUNCTION AND EXAMPLE Since the release layer is formed on the support by thermal transfer from the thermal transfer ribbon when the transfer sheet is produced, it is not necessary to prepare a special support.

Further, in the present invention, since the ink layer and the adhesive layer are function-separated as separate layers, the composition and the like of each layer can be determined so that each layer can exhibit its optimum function.

Further, the transfer of the obtained transfer sheet to the object is carried out by pressure transfer or heat transfer in the first invention, but is carried out by wet transfer in the second invention.

That is, in the second aspect of the invention, the obtained transfer sheet is immersed in a hydrophilic solvent to dissolve or swell the release layer, whereby desired image-like ink layers are bonded by an adhesive layer and integrated. The prepared product is separated from the support and attached to an object. Since the integrated product has no support, it is flexible, so that it can be easily transferred to an object having a complicated curved surface. Further, since the integrated product easily adheres in a wet state, it can be easily adhered to the inner surface of a narrow space.

The present invention will be specifically described below.

The print image 13 is transferred by rubbing with a pressure to apply pressure, or by heating with a hot iron or iron. Thus, as shown in FIG. 4, the print image 13 is formed on the object 21.

In the above, the printed image on the normal transfer sheet 11
13 is an inverted image of the left and right when viewed from the direction of the arrow in FIG.
When this is transferred onto the object 21, it becomes a normal image as seen from the viewing side (arrow direction) as shown in FIG. However, as shown in FIG. 5, when the object 22 is a transparent or semi-transparent sheet-like object and the print image 13 is transferred to the opposite side as viewed from the viewing side (arrow direction), the transfer sheet in FIG. The printed image 13 on 11 is a normal image when viewed from the direction of the arrow.

In the case of the print image 13 on the transfer sheet 11 shown in FIG. 2, the print image 2a of the release layer 2 is a solid print image, and the print image 3a of the ink layer 3 on the release image 2 is a desired character or pattern. The pattern image is formed in a pattern, and the print image 4a of the adhesive layer 4 thereon is a solid print image. This solid image includes an image obtained by solid-printing the entire release layer 2 or adhesive layer 4 shown in FIGS. 1A and 1B.
The size does not matter as long as it has an area including. Further, the print image 2a of the release layer 2 and / or the print image 4a of the adhesive layer 4 may be matched with the print image 3a of the ink layer 3. FIG. 6 shows an example in which the print image 2a and the print image 4a both match the print image 3a.

In order to obtain an image having high fastness, a mixture of a wax-like substance and a heat-melting resin as a heat-melting vehicle, for example, 100 parts by weight of the both (weight part, the same applies hereinafter) is used. A mixture of 10 to 100 parts of meltable resin and 0 to 90 parts of wax-like substance is preferably used.

As the colorant, various organic and inorganic color pigments and dyes such as carbon black are used.
The content of the colorant in the ink layer is 10 to 30% (% by weight,

If necessary, other compounding agents such as a dispersant may be added to the ink layer.

The adhesive layer in the first aspect of the invention exhibits a heat transfer property when the transfer sheet is prepared, and exhibits a pressure-sensitive adhesive property or a heat-sensitive adhesive property when transferring an image on the transfer sheet to an object.

As the adhesive having pressure-sensitive adhesiveness, an adhesive having an initial tackiness that is not so strong is preferable so as not to impair the running property of the ink ribbon. As such an adhesive,
For example, those containing a wax-like substance and a tackifier resin as main components can be mentioned. As the wax-like substance in this pressure-sensitive adhesive, those exemplified for the above-mentioned release layer can be used, but candelilla wax, carnauba wax, paraffin wax, microcrystalline wax and the like are particularly preferably used.

As the tackifier resin, petroleum resin, rosin resin, ketone resin, terpene resin, phenol resin, polyacrylic ester, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, polyisobutylene, etc. An ordinary one is appropriately selected and used.

The substrate 1 in the first invention is generally used as a polyester film such as a polyethylene terephthalate film or a polyethylene naphthalate film, a polycarbonate film, a polyamide fill, an aramid film, or a film for a substrate of an ink ribbon of this type. Various types of plastic film used can be used. It is also preferable to use a high density thin paper such as a condenser paper as a base material. The thickness of the base material is about 2 to 10 μm, especially 3 to 7 μm from the viewpoint of improving heat conduction.
About m is preferable.

When the above-mentioned plastic film is used as the base material, a silicone resin, a fluororesin, a nitrocellulose resin, or various kinds of lubrication heat resistance modified by these on the back surface (the surface which is in contact with the heating head) A conventionally known stick-preventing layer made of a resin or a mixture of these heat-resistant resins with a lubricant may be provided.

In the thermal transfer ribbon of the above-mentioned embodiment, the release layer 2, the ink layer 3 and the adhesive layer 4 are usually the same in size, and the size is the purpose of use, whether the ribbon is tape-shaped or sheet-shaped. It may be appropriately determined depending on the item.

In the first invention, the thermal transfer ribbon is used to sequentially transfer each layer onto the support 12 to form an image 13 by means of a thermal transfer printer. The support 12 is subjected to special processing such as release treatment. A relatively smooth paper or plastic film that has not been applied can be used. As the plastic film, those exemplified as the base material of the thermal transfer ribbon can be used. When the transfer from the transfer sheet is pressure-sensitive transfer, a polyolefin film such as a polyethylene film or a polypropylene film can also be used. It is preferable that the support is transparent or semi-transparent because the transfer operation is easier if the print image 13 is visible from the back surface during transfer to the object.

In order to enable transfer onto a complicated curved surface, it is preferable that the support is as thin as possible without impairing handleability, and for example, about 50 to 200 μm is preferable.

In the thermal transfer ribbon of the above embodiment, the release layer, the ink layer and the adhesive layer are repeatedly arranged on a single strip-shaped substrate, but the release layer is formed on the single strip-shaped substrate. The ink layer and the adhesive layer may be arranged side by side in a stripe shape extending in the longitudinal direction of the substrate. It is also possible to prepare three types of thermal transfer ribbons each having a release layer, an ink layer, and an adhesive layer provided on different strip-shaped base materials, and use these to form a transfer sheet.

In the above embodiment, the color of the printed image 13 obtained on the transfer sheet is the same color as the color of the ink layer 3 of the thermal transfer ribbon.

When a multicolor image is desired, for example, three types of transfer sheets on which a yellow image, a magenta image and a cyan image are respectively formed are prepared, these images are superposed on the object, and subtractive color mixing is performed. It may be possible to obtain a multicolor image, but the operation is complicated.

Therefore, it is preferable to form a multicolor image on the transfer sheet so that a multicolor image can be obtained on the object by one transfer operation.

FIG. 7 is a plan view showing an example of a thermal transfer ribbon used for such an application, and the ink layer 3 is composed of a yellow ink layer 3Y, a magenta ink layer 3M and a cyan ink layer 3C. In order to prepare a transfer sheet using this thermal transfer ribbon, the release layer 2 is first transferred onto the support 12, and then the yellow ink layer 3Y, the magenta ink layer 3M and the cyan ink layer 3C are sequentially transferred to form a color. An image is formed, and finally the adhesive layer 4 is transferred.

The order of arranging the yellow ink layer 3Y, the magenta ink layer 3M, and the cyan ink layer 3C is not limited to the order shown in FIG. 7, and can be appropriately changed depending on the transfer order.

The composition of the yellow ink layer 3Y, the magenta ink layer 3M, and the cyan ink layer 3C is the same as that of the ink layer 3.

It should be noted that 3 of yellow, magenta and cyan
When it is difficult to obtain a clear black color by superimposing colors, a black ink layer containing a black colorant such as carbon black or nigrosine base may be added to the ink layers of the three primary colors.

Next, the second invention will be described.

Also in the second invention, the first invention is different except that the release layer 2 used is soluble in a hydrophilic solvent and the adhesive layer 4 has a property capable of integrally holding the printed image of the ink layer. In the same manner as described above, the transfer sheet 11 is obtained by thermal transfer. In a preferred embodiment, a thermal transfer ribbon having a layer arrangement as shown in FIGS. 1A and 1B is used to form an image 13 on a support 12 as shown in FIG. Get 11 In this case, the adhesive layer 4 is solidly printed as shown in FIG.

In the second invention, the obtained transfer sheet
For example, as shown in FIG. 8, the transfer of the image 13 of the image 11 onto the object is performed by immersing the transfer sheet 11 in a hydrophilic solvent such as water or alcohol to form the image 3a of the ink layer and the image 4a of the adhesive layer. 13A is peeled from the support 12, and then the integrated body 13A is attached to the object 21, as shown in FIG. 9, and then heated and dried to form an image 13A on the object 21.

From the viewpoint of safety, water or a lower alcohol such as ethyl alcohol, or a mixture thereof is preferably used as the hydrophilic solvent.

When the monolith 13A is peeled from the support 12, the release layer 2a does not have to be completely dissolved, but may be partially dissolved or may be swollen or the like so that the monolith 13A is easily peeled. .

The release layer soluble in a hydrophilic solvent in the thermal transfer ribbon used in the second invention is preferably composed mainly of a hydrophilic resin. Such hydrophilic resins include gum arabic, dextrin, cellulosic resins (hydroxyethyl cellulose, carboxymethyl cellulose,
Examples thereof include nitrification cotton, ethyl cellulose and the like), polyvinyl alcohol and the like.

If necessary, a compounding agent such as a plasticizer or oil may be added to the release layer.

The adhesive layer in the second aspect of the invention exhibits a thermal transfer property when a transfer sheet is prepared, and when the transfer image on the transfer sheet is transferred to an object, it holds the print image of the ink layer integrally. It is necessary to have a holding property (when transferred to an object, the image can be held in a thin film form until the image is separated from the support and attached to the object).

An example of such an adhesive layer is one mainly composed of a film-forming thermoplastic resin. Examples of such resins include polyamide resins, ethylene-vinyl acetate copolymers, ethylene-ethyl acrylate copolymers, polycaprolactone resins, and the like.

A wax-like substance may be added to the adhesive layer as long as the film-forming property is not impaired.

The ink layer in the second invention may be the same as in the first invention.

In the first invention, as shown in FIG. 10, a thermal transfer ribbon composed of two layers, that is, a release layer 2 and an ink layer 3 having pressure-sensitive adhesive property or heat-sensitive adhesive property, is used and shown in FIG. Print image 2a of release layer 2 and print image 3a of ink layer 3
