The label 1 with a sublimation transfer image of the present invention has a laminated structure in which an adhesive layer 3, a sheet substrate 4, and an image receiving layer 5 are sequentially laminated on a release sheet 2 as shown in FIG. Has a function of a thermal transfer sheet used in a normal thermal transfer recording system. In the drawing, reference numeral 6 denotes a photographic image, and reference numeral 7 denotes a cut line obtained by the half-cut processing.

In the label 1 of the present invention, a label portion 8 is formed by the adhesive layer 3, the sheet substrate 4, and the image receiving layer 5.
Has a structure that can be peeled between the release sheet 2 and
As shown in FIG. 4, the label portion 8 can be easily peeled off the release sheet 2 along the cut line 7 and can be separated.

The label portion 8 is a portion that adheres to various articles after being detached from the release sheet 2. The image receiving layer 5 is provided on the sheet substrate 4, and the back surface of the substrate 4 can adhere to the surface of the desired article. The adhesive layer 3 is provided.

The sheet substrate 4 is preferably a foamed polyethylene terephthalate film particularly for obtaining a high print density.
The thickness of the substrate 4 is 10 to 200 μm.

The image receiving layer 5 is a layer capable of receiving a sublimable dye migrating from the color material layer of the thermal transfer sheet by heating during thermal transfer recording, thereby forming a sublimation transfer image 6 on the layer. Any material can be used as long as it is a material which is conventionally used for forming an image receiving layer of a heat-receiving sheet. For example, a saturated polyester resin, a polyacrylate resin, a vinyl chloride-vinyl acetate copolymer may be used. And a mixture of a polyester resin and a vinyl chloride-vinyl acetate copolymer. Among them, a mixture of a polyester resin and a vinyl chloride-vinyl acetate copolymer is preferable. The mixing ratio with the polymer is preferably 50 to 200 parts by weight of the vinyl chloride-vinyl acetate copolymer per 100 parts by weight of the polyester resin. When a mixture of a polyester resin and a vinyl chloride-vinyl acetate copolymer is used, the light resistance of an image transferred and formed on the image receiving layer can be improved.

On the surface of the image receiving layer 5, a release agent layer for adding good releasability from the thermal transfer sheet can be provided as necessary. The release agent layer can be formed by including a release agent in the case of a release agent having good compatibility with the above-mentioned material for forming an image receiving layer. It can be formed by coating thinly on the layer surface. As the release agent, a silicone oil (for example, a combination of an epoxy-modified silicone and an amino-modified silicone), a fluorine-based or phosphate-based surfactant, or the like can be used.

Examples of the material of the adhesive layer 3 include polyacrylate,
Acrylic copolymer, natural rubber, synthetic rubber, petroleum resin,
Examples include block copolymers such as SIS and SBR. If necessary, an adhesive reinforcing agent, a plasticizer, a filler, and the like can be added to the adhesive.

If necessary, the release sheet 2 may be provided with a release layer so that the sheet 2 and the label portion 8 (specifically, between the adhesive layer 3 and the release layer) can be easily released. .
This release layer is formed using a silicone-based release agent mainly composed of polymethylsiloxy acid or the like, polyolefin, or the like.

The photographic image 6 in the label 1 of the present invention is a sublimation transfer image formed by applying a normal thermal transfer recording method to the heat transfer sheet having the above-described configuration. The sublimation dye in the color material layer of the thermal transfer sheet is transferred to the image receiving layer 5 by the heating of the thermal head whose heating is suppressed by the corresponding electric signal.

The image content of the image 6 is not particularly limited, and can be configured with desired content, and may be characters, symbols, figures, and the like.

This image 6 has four or more “frames” as one unit of the image content. In this embodiment, as shown in FIG. 1, an example of an image composed of four frames A, B, C and D is shown. (Note that in FIG. 1, the above-mentioned alphabet symbol itself may be regarded as the image 6.)

An image of the content can be easily obtained.

In the label 1 of the present invention, as shown in FIG. 2, the label portion 8 is subjected to a half-cut process, and the cut line 7 by this process divides each frame of the image 6 and divides the image 6 by the half-cut process. An image 6 is formed for each frame. For example, as shown in FIG.
The image is clearly divided for each of the C and D frame images. The half-cut process is for enabling the label portion 8 having one frame of the image 6 surrounded by the cut line 7 to be accurately and orderly separated from the release sheet 2. Also, this processing is performed when the label portion 8 is peeled off.
Since the end portion of the label portion starts to be spontaneously peeled off only by slightly bending itself, it is effective as a trigger for starting the peeling.

The half-cut processing in the present embodiment includes A, B, C,
Although the boundaries (lines) of the images 6 composed of D frames are applied so as to be joined to each other, the present invention is not limited to such a processing method, and for example, A, B, C, D
May be applied so that the boundaries between the images 6 are separated from each other (in other words, the images are completely separated by the cut lines).

The cut line 7 can be set in accordance with the image content of the image 6, such as the type of the line, the shape of the line, and the like. For example, the shape of the line is not limited to a quadrilateral consisting of straight lines as shown in FIG. , A circle, a triangle, or the like.

Is provided with a cutting blade 13 arranged along a cut line to be provided on the label, while the press machine 10 comprises a fixed base 14 and a press plate 15 which can move up and down. Therefore, according to this punching machine, the present label 1
Is placed on the lower plate 12 of the half-punching machine 9, the upper plate 11 is lowered, and the label 1 is clamped between the upper and lower plates (at this time, it is determined whether the cutting blade 13 is located at a predetermined position on the label). After that, the half punching machine 9 holding and fixing the label is set in the press machine 10, and the press platen 15 is lowered to press the entire half punching machine, so that the cutting blade 13 is able to remove the label. , And a cut line is cut at a predetermined position of the label 1 to perform a half-cut process. In the drawing, reference numeral 16 indicates that the cutting blade 13 has a predetermined depth in the label 1,
The upper plate 11 descends in order to enter by the thickness of
Is an adjustment stopper for stopping at a predetermined position.

In the present invention, a detection mark can be provided on a label. The detection mark is extremely useful when performing accurate positioning with the thermal transfer sheet during image formation. For example, a detection mark that can be detected by the photoelectric tube detection device can be provided on the back surface of the release sheet 2 by printing or the like.

Further, in the present invention, an intermediate layer having cushioning properties, heat insulation properties, and the like can be provided between the sheet substrate 4 and the image receiving layer 5, and when this intermediate layer is provided, an image having little noise and corresponding to image information is provided. Can be transferred and recorded with good reproducibility. Examples of the material forming the intermediate layer include urethane resin, acrylic resin, ethylene-based resin, butadiene rubber, and epoxy resin. The thickness of the intermediate layer is 2

Further, in the present invention, the back surface of the release sheet 2 can contain an antistatic agent. The incorporation of an antistatic agent has the effects of making it possible for the labels to slide more smoothly and for preventing adhesion of dust and the like to the labels during transfer recording. The antistatic agent may be contained in the release sheet 2 or the image receiving layer 6, or may be provided on the back surface of the release sheet 2 as an antistatic agent layer.

The label of the present invention can be provided with an active layer on the back surface of the release sheet 2. Labels at the time of transfer recording are stacked and sent out one by one to perform transfer. At this time, if a slip layer is provided, the slip between the sheets becomes smooth, and one by one in parallel with the antistatic treatment described above. Can be taken out accurately. Examples of the lubricating layer include a methacrylate resin such as methyl methacrylate or a corresponding acrylate resin, and a vinyl resin such as a vinyl chloride-vinyl acetate copolymer.

The label 1 of the present invention is usually subjected to a half-cutting process after forming the image 6, but after performing the half-cutting process in advance, the image is formed so as to fall within the frame range formed by the cut lines. Is also good.

In actual use of the present invention label 1 having the above-described configuration, the label portion 8 is peeled off the release sheet 2 along the cut line 7 by the half-cut processing as shown in FIG. As shown in the figure, a label portion 8 having a photographic image 6 and having a predetermined shape defined by a cut line is attached to a desired adherend 17.
