[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a thermal transfer application film used for marking a mark such as a character or a figure on an adherend, and more particularly to a countermeasure for mark misalignment.

[0002]

2. Description of the Related Art Conventionally, there is a method of thermally transferring a mark by using an application film having an adhesive layer formed on one surface of a support such as a film or paper. In this method, first, a hot-melt adhesive layer is formed on one surface of a design film, and release paper is attached to the hot-melt adhesive layer to form a marking sheet having a three-layer structure. Next, this marking sheet is cut into a mark shape such as a desired character or figure to obtain a transfer material. Then, after temporarily fixing the transfer material to the adhesive layer of the application film, only the release paper is peeled off from the transfer material, and a mark having a two-layer structure consisting of the design film and the hot melt adhesive layer is applied to the application film. Attach it. After that, the application film to which this mark is attached is set at a position to be marked on the adherend, heated and pressed, and then the support of the application film is removed so that the mark is thermally transferred to the adherend. Has been done.

[0003]

However, in the above-mentioned conventional application film, there is no mark for temporarily fixing the mark-shaped transfer material, and the transfer film is applied one by one by the operator. Since it is necessary to place the transfer materials in a line, it is very difficult to arrange the transfer materials as desired due to the gap between the transfer materials that are adjacent to each other or the inclination of the transfer materials. There was a problem.

The present invention has been made in view of the above points, and an object of the present invention is to easily and reliably perform marking without misalignment by providing a support with a reference for marking. To try.

[0005]

In order to achieve the above object, the present invention provides a transfer material having a pressure-sensitive adhesive layer formed on one surface of a support and having a mark thermally transferred to an adherend. For the application film for thermal transfer that is peelably supported on the substrate, the following means for solving have been taken.

That is, the first solution means of the present invention employs a transparent or translucent support as the support. Further, it is characterized in that a positioning line made of a straight line for positioning the transfer material is provided.

A second solving means of the present invention is characterized in that, in the first solving means, a plurality of positioning lines are provided and each of the positioning lines is extended in parallel to the longitudinal direction of the film.

A third solving means of the present invention is characterized in that, in the first solving means, a plurality of positioning lines are provided, and each positioning line is extended in parallel to a film width direction orthogonal to a film longitudinal direction. To do.

A fourth solution means of the present invention is the first solution means, wherein a plurality of positioning lines extend in parallel to the longitudinal direction of the film and a plurality of alignment lines extend in parallel to the film width direction orthogonal to the straight lines. It consists of a straight line and. Further, each straight line is crossed with each other to form a lattice.

A fifth solving means of the present invention is characterized in that, in any one of the second to fourth solving means, the interval between the positioning lines adjacent to each other is set within a range of 1 to 500 mm. To do.

[0011]

With the above structure, in the first to fifth means for solving the problems of the present invention, the transfer material is arranged in order on the application film with reference to the positioning line. Furthermore, the position of the transfer material with respect to the adherend can be seen through the application film,
Position adjustment, that is, positioning of the transfer material is performed easily and accurately.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1A shows a thermal transfer application film 1 according to an embodiment of the present invention. The application film 1 is provided with a transparent or semitransparent support 2, and an adhesive layer 3 is formed on one surface of the support 2. The support 2 may be a transparent or translucent plastic film such as polyvinyl chloride, polypropylene, polyethylene terephthalate, or acrylic resin, or a paper such as tracing paper as long as it is transparent. Further, on the pressure-sensitive adhesive layer 3 side of the support 2, a plurality of positioning lines 4, 4, ..., Which are straight lines for positioning the transfer material 5 to be described later, are printed, and each positioning line 4 is formed by a solid line. And extend parallel to the longitudinal direction of the film.

The positioning line 4 is shown in FIG.
Not limited to (a), for example, it may extend parallel to the film width direction orthogonal to the film longitudinal direction (see FIG. 1 (b)). Furthermore, the positioning line 4
Is composed of a plurality of straight lines extending in parallel in the longitudinal direction of the film and a plurality of straight lines extending in parallel in the film width direction orthogonal to the respective straight lines. You may make it cross | intersect and form a grating | lattice (refer FIG.1 (c)). Further, the line type of each positioning line 4 is not limited to the solid line, and is represented by a broken line (see FIG. 2A), a one-dot chain line (see FIG. 2B), and a two-dot chain line (see FIG. 2C). May be Although not shown, for example, the positioning line 4 extending in the longitudinal direction of the film may be a solid line, and the positioning line 4 extending in the film width direction may be a broken line.

Further, the positioning lines 4, which are adjacent to each other,
The interval of 4 is set in the range of 1 to 500 mm. The reason why the spacing between the positioning lines 4 and 4 is set in the range of 1 to 500 mm is that the positioning work of the transfer material 5 is performed visually, so that a spacing narrower than 1 mm is unnecessary, and the application is also performed. Film 1 is generally 100
Since the width is 0 mm or less in most cases, an interval wider than 500 mm is actually unnecessary. A particularly preferred distance is 1 to 200 mm.

On the adhesive layer 3 of the application film 1 thus constructed, the transfer material 5 having the mark 9 to be thermally transferred to the adherend 10 is detachably supported, and is used for the thermal transfer of the mark 9. To be

Next, a transfer example using the application film 1 will be described with reference to FIGS.

First, a transfer material 5 as shown in FIGS. 3 (a) and 3 (b) is prepared. The transfer material 5 uses a marking film composed of a laminate of a design film 6, a hot-melt adhesive layer 7 and a release paper 8 as a material, of which the design film 6 and the hot-melt adhesive layer excluding the release paper 8 are used. 7 is an unnecessary portion removed so as to represent a mark 9 such as a desired character or figure. In FIG. 3A, two transfer materials 5 and 5 are used, and one of the transfer materials 5 (the upper one in FIG. 3A) has “BANDO”.
Mark 9 formed by arranging the Roman letters and a belt-shaped straight line of a predetermined width side by side is formed on the other transfer material 5 (the lower one in FIG. 3A). Are formed. In addition, in practice, the transfer material 5 (see FIG.
The mark 9 on the upper side in (a) is black, and the mark 9 on the other transfer material 5 (lower side in FIG. 3A) is red, but the colors may be identified in the drawing. Therefore, for the sake of convenience, the mark 9 of the one black transfer material 5 (the upper one in FIG. 3A) is painted black, and the red transfer material 5 (the lower one in the FIG. 3A) is used. ) Marks 9 are outlined to identify them.

Next, as shown in FIGS. 4 (a) and 4 (b), positioning lines 4, 4, ... Consisting of straight lines at intervals of 1 cm that form a lattice orthogonal to each other are formed on the surface opposite to the adhesive layer 3. The long application film 1 wound in a roll shape is cut into a predetermined length, and the adhesive layer 3 of the application film 1 and the marks 9 of the two transfer materials 5 and 5 face each other. Stick both.
At this time, the transfer material 5 having the red mark 9 is attached to the application film 1 based on the straight line extending in the film width direction of the positioning line 4, that is, along the straight line extending in the film width direction. Further, the transfer material 5 having the black mark 9 is attached to the application film 1 based on the transfer material 5 having the red mark 9 and the intersecting straight line. Therefore, the transfer lines 5 can be arranged on the application film 1 without misalignment by using the positioning lines 4, 4, ... As straight lines that intersect in a grid pattern as a reference for alignment (see FIG. 5A). ).

Thereafter, as shown in FIGS. 5 (a) and 5 (b), only the release paper 8 is peeled off from each of the transfer materials 5 to form a two-layer structure consisting of the design film 6 and the hot melt adhesive layer 7. The mark 9 is attached to the application film 1.

After that, as shown in FIGS. 6A and 6B, the application film 1 to which the mark 9 is attached is set on the adherend 10 at a portion to be marked. At this time, since the mark 9 and the adherend 10 can be seen over the application film 1, by aligning the mark 9 with the positioning line 4 of the application film 1 as a reference, the mark 9 and the adherend 1 are not displaced.
It can be easily and accurately placed at zero.

After that, the adherend 10 on which the mark 9 is arranged is heated and pressed to integrally bond the mark 9 to the adherend 10 so as not to separate, and then the support 2 of the application film 1 is attached. After removal, the two marks 9, 9 are thermally transferred to the adherend 10 as shown in FIGS. 7 (a) and 7 (b). The thermally transferred marks 9 are arranged in an orderly manner without being displaced in the vertical and horizontal directions.

[0023]

As described above, according to the present invention according to claims 1 to 5, the support constituting the application film is transparent or semi-transparent, and the positioning line is provided on the support. The transfer material can be arranged on the application film in an orderly manner based on the above-mentioned positioning line, and the marks can be positioned on the adherend while observing the orderly arranged transfer material through the application film. Without the mark, the mark can be easily and accurately heat-transferred to the adherend.
