Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a method for producing a transfer sheet that is widely commercialized, for example, as a sticker or a seal.

<Prior art> A transfer sheet capable of transferring beautiful and clear print lines such as letters, figures, symbols and patterns to a subject made of various materials in a so-called one-touch operation pressing type as if they were directly printed. As the above, JP-A-61-232399 has already been proposed.

Then, in this case, the printing layer (B) is formed from an adhesive composition containing a surfactant, and further, such printing layer (B) is used as a base material and the same as the same on the surface thereof. The printing layer (C) of the ink of the image line is set in the overprint state.

<Problems to be Solved by the Invention> However, in the case of the above-mentioned known invention, the printing layer (B) is formed from the adhesive composition itself. In addition, therefore, unless it is a so-called solid printing form, the printing layer (B) is partially adhered in a dotted state so as to draw a constant image line on the release sheet (A).

Therefore, when the surface is scratched by a nail or the like or repeatedly rubbed while being used as a finished product or transferred to a subject, the printed layer (B) easily loses its shape and finally a release sheet ( As a result, it will be dropped or disappeared from A). This means that even if the printing layer (C) is overprinted on the surface of the printing layer (B), the base material of the printing layer (C) is composed of the adhesive composition, so to speak, on sand. It will be exactly the same, and it will happen in exactly the same way.

Further, it is difficult to apply the adhesive composition as a printed layer (B) on which a constant image line is drawn onto the surface of the release sheet (A) in a scattered and partially adhered state with high accuracy. And much less, a printed layer (B) of such an adhesive composition,
It is extremely difficult to match the drawing lines between the ink and the printing layer (C). If even a slight misalignment occurs, the beautifulness of the drawing lines will be immediately deteriorated and the commercial value will be diminished. Therefore, it is impossible to obtain a particularly thin and sharp drawing line. This means that the thinner the image line, the poorer the adhesive strength of the printing layer (B) to the release sheet (A).
That is true.

Therefore, in practice, the printing layer (B) of the adhesive composition, which is a base material for overprinting the printing layer (C) with ink, is adhered to the release sheet (A) with a slightly large area in advance. By compensating for the misalignment of the drawing line by adding it,
The printed layer (B) of the base material is made transparent to compensate for the decrease in the commercial value.

However, even if the printing layer (B) is made transparent so that it can be adhesively administered in a large area, since it is transparent as a manufacturing method, it is rather a printing layer (C) made of ink. It becomes difficult to match the drawing lines with the above, and this becomes more remarkable as the drawing lines become thinner, and it is not possible to manufacture with high efficiency.

Further, it is necessary to prepare a printing plate corresponding to two kinds of the printing layer (B) of the adhesive composition and the printing layer (C) of the ink, and not only the plate making cost becomes expensive, but Since the printing work must be performed twice, the mass production effect cannot be expected to the maximum.

The above-mentioned problems have been solved by the applicant of the present invention.
Although it was solved by No. 282127, the results of intensive research after that show that, in the case of this prior invention, since the plastic film (13) is used as the base material of the printed image (15), The printed image (15) from the surface of the film (13) is still inferior in vividness or gloss.
It is considered that this is unavoidable due to the nature of the plastic film itself, and it is considered that there is a limit in itself in making the printed image (15) shine from the back side.

<Means for Solving the Problems> The present invention is intended to improve such problems and expand the applications as products thereof. Therefore, as a method of manufacturing a transfer sheet, first, a release sheet is used. After adhering the metal vapor deposition film to the surface with an adhesive so that the metal vapor deposition layer is exposed face-to-face, and applying a certain image line to the surface of the metal vapor deposition layer by printing or hot stamping, It is characterized in that only the metal vapor deposition film itself and the adhesive which are present at the location where the image lines are not provided are dissolved by administration of a chemical, and secondly, a metal comprising a transparent plastic film and a metal vapor deposition layer. With the vapor-deposited film exposed to the surface, the plastic film is attached to the surface of the release sheet with an adhesive and integrated, and then the plastic film is exposed to the surface. After applying a certain image line by a method such as printing or hot stamping, it is possible to dissolve the metal vapor deposition film itself and the adhesive which are present in the non-imaged area by the administration of chemicals or water. It is a feature.

<Operation> According to the above configuration, the metal vapor deposition layer of the metal vapor deposition film or the surface of the transparent plastic film which is the base material thereof is provided with a certain image line, and then the metal vapor deposition present at the non-application point is provided. Only the film itself and the adhesive to the release sheet are dissolved by the administration of chemicals or water to leave an image line as a transfer sheet, so that the image line is thin and sharp. Also, it can be manufactured extremely easily with no danger of losing its shape, falling off, or disappearing. In particular, the drawing line reflects the luster of the metal deposition layer from the back side. It is also possible to finish it as a transfer sheet that can be seen very clearly.

<Examples> Hereinafter, the details of the present invention will be described with reference to the drawings.
FIG. 3 shows the transfer sheet (A) according to the first embodiment and its manufacturing process. (11) is a paper or plastic film,
Release sheet (separator) made of other sheet materials
Needless to say, the surface is subjected to a mold release treatment such as silicon.

In manufacturing the transfer sheet (A), first,
As a process, as shown in FIG. 3 (I), the release sheet (11)
Through the adhesive (12) to the entire surface of the metal deposition film (1
3) is attached and integrated, but the metal vapor deposition film
As (13), which can be dissolved by the chemicals described below, and on the surface of a transparent plastic film (13a), a metal such as aluminum, zinc, or silver is used, and in particular, a metal vapor deposition layer (13b) thereof is used. Is exposed to the surface so that the release sheet (11) is bonded and integrated with the surface of the release sheet (11).

Next, as a second step, as is apparent from FIG. 2 (II), desired printing letters (14) are directly applied to the surface of the metal vapor deposition layer (13b) of the metal vapor deposition film (13) by a desired printing plate (14).
A constant drawing line (15) consisting of a pattern is added. Then, the gloss generated from the metal vapor deposition layer (13b) is reflected on the image line (15), and the image line (15) receives a so-called backing action of gloss, so that it can be seen clearly from above. Can be taken.

In this case, a printing ink that is not dissolved by the chemicals described below is used to protect the deposited metal vapor deposition film (13) itself and the adhesive (12) directly below it from the dissolution. Then, as long as this purpose can be achieved, it is possible to use a transparent printing ink or to apply a coloring color to the image line (15).

Also, while using various kinds of common plate type printing machines such as silk screen printing, the image line (15) is a metal vapor deposition layer.
It can be freely attached to the surface of (13b). Further, it can be said that the drawing line (15) can be formed by adopting a hot stamping method instead of the printing method. Incidentally, since the metal vapor deposition layer (13b) is exposed to the surface and the image line (15) is directly applied thereto, the plastic film (13) which is the base material thereof.
In a), it is not necessary to set this transparently.

In any case, as shown in Fig. 3 (III), a constant drawing line (15)
After applying, the chemical is applied to the entire surface of the metal deposition film (13) including the drawing line (15), and as shown in the same figure (IV), the drawing line (15) is not applied. The metal vapor deposition film (13) itself located at the location (S) and its release sheet (1
Only the adhesive (12) to 1) is dissolved and disappeared by the action of the chemical.

As the chemical, for example, while using various solutions such as ethyl acetate, methyl ethyl ketone, Rucker thinner, acetone, etc., in the state of Fig. (III), spraying it from a nozzle outside the figure, or a reservoir for the chemical It is dipped in or administered by other working techniques. In other words, in contrast to such chemicals metal deposition film (13) and its adhesive (12) have solubility, contrary to,
The above-mentioned image (15) has its insolubility.

Finally, in order to cover the entire surface of the image line (15) in the state of FIG. 3 (IV), a transfer and protection masking sheet (16) made of a transparent plastic film is finally attached and integrated. , Mushroom transfer sheet as shown in Fig. 1 and 2 (A)
Is completed as. (17) shows the adhesive applied to the back surface of the masking sheet (16), the adhesive force is weaker than that of the adhesive (12) attached to the release sheet (11), Needless to say.

The transfer sheet (A) manufactured in this way is used as a specific product such as a sticker or a sticker as a release sheet (1) when used for transfer to the subject (M) as shown in FIG.
After being peeled off from 1), it is firmly adhered and integrated to the surface of the subject (M) through the attached adhesive (12) by a so-called one-touch type pressing operation. Of course, after the transfer to the subject (M), the masking sheet (16) is peeled off as shown in FIG.

Next, FIGS. 5 and 6 show a transfer sheet (B) according to the second embodiment.
And the manufacturing process thereof, but in terms of their structure,
The main points different from the first embodiment shown in the figure are as follows.

That is, in this case, via the adhesive (12) to the release sheet (11),
When the metal vapor deposition film (13) is attached and integrated, the metal vapor deposition layer (13b) is faced down, so that the transparent plastic film (13a), which is the base material for adhering the metal, is exposed. It adheres to the surface of the release sheet (11). Then, a certain image line (15) is applied to the surface of the transparent plastic film (13a) by the printing method of various plate types or the hot stamp method.

Even if such a manufacturing method is adopted, a metal vapor deposition layer (13) is formed on the image line (15) through a transparent plastic film (13a).
Since the gloss of b) will be reflected, the line
It is possible to obtain a remarkably clear transfer sheet (B) of (15). On the contrary, compared with the method of directly applying the image line (15) to the surface of the metal vapor deposition layer (13b) as in the first embodiment, The printing can be performed extremely smoothly without restriction.

Further, when adopting such a manufacturing method, it is of course possible to dissolve it by using the chemicals of the above-mentioned first embodiment, but especially when water instead of this is used, the drawing line (15) It is also possible to dissolve only both the metal vapor deposition film (13) located at the non-application point (S) and the adhesive (12) to the release sheet (11). If a water-soluble one is adopted as the transparent plastic film (13a) of the metal vapor deposition film (13), the metal vapor deposition layer (13b) adhered as a base material by dissolving this is dissolved. )
As a result, they will be lost together.

At this time, needless to say, the adhesive (12) is also determined to be water-soluble, while the image line (15) is applied from a water-insoluble printing ink or the like. Since such dissolution with water can be performed by using a working method such as washing with water, the safety in working hygiene can be improved as compared with chemicals.

Since the other constructions of the second embodiment are substantially the same as those of the first embodiment shown in FIGS. 1 to 3, the corresponding reference numerals to those shown in FIGS. The detailed description is omitted.

<Effects of the Invention> As described above, in the transfer sheet manufacturing method according to the present invention,
The metal vapor deposition film (13) is adhered to the surface of the release sheet (11) with the adhesive (12) so that the metal vapor deposition layer (13b) is exposed face-to-face, and the surface of the metal vapor deposition layer (13b) is integrated. After applying a certain image line (15) by a method such as printing or hot stamping, the metal vapor deposition film (13) itself and the adhesive which are present at the non-application point (S) of the image line (15) Since only (12) is dissolved by administration of a drug, it has an effect of completely solving not only the problems inherent in the known invention at the beginning but also the problems remaining in the prior invention of the applicant.

That is, in the present invention, the surface of the metal vapor deposition layer (13b) in the metal vapor deposition film (13) is provided with a constant image line (15), so the gloss emitted from the metal vapor deposition layer (13b) is (1
Reflecting it from the back to 5), the image line (15) will be sharpened as if it were a relief, and the image line (15) is remarkably elegant.
As a result, it can be finished as a transfer sheet. For example, on the surface of the vapor-deposited layer (13b) in which the metal is aluminum, by applying an image line (15) with yellow printing ink
The image line (15) can be colored as a gold color by the backing action of the vapor deposition layer (13b), and if it is applied by using a transparent printing ink, the image line (15) also becomes a silver color. The application as a transfer sheet can be expanded to a wide range.

Such an effect can be achieved in substantially the same manner even when the method described in claim 2 is adopted. Since a plastic film (13a) which is particularly transparent is used as a base material for attaching the metal vapor deposition layer (13b), the image line (15) is applied to the surface of the plastic film (13a). This is because the gloss of the metal vapor deposition layer (13b) is reflected in 15) from the back side.

In any case, according to the present invention, one printing plate or the like is sufficient, and it is sufficient to carry out the work such as printing and hot stamping once, and the mass production effect can be expected to the maximum, and an extremely thin and sharp image line can be obtained. Since (15) can be freely added as it is in a state of excellent durability, abrasion resistance and sharpness, it can be said that it is remarkably suitable for practical use.
