Description of the Related Art As a reversible thermosensitive recording material for displaying or erasing a visible image, a leuco dye (also called a leuco dye) or a low-molecular organic compound whose color tone reversibly changes depending on the conditions of a heating temperature and a cooling rate after heating. A compound in which a compound is dispersed in a resin base material is known.

A leuco dye is a reduction type dye comprising a colorless or light-colored electron-donating dye precursor, and a reversible thermosensitive recording material composition using the same is provided with a leuco dye and an acidic dye for forming the leuco dye. A color-developing agent comprising an amphoteric compound having a group and a basic group capable of decoloring the formed leuco dye is blended (JP-A-2-188293).
Leuco dyes, which are electron-donating dye precursors, have a color-forming and decoloring effect by controlling thermal energy, so that one of a coloring action by an acidic group or a decoloring action by a basic group has priority. .

Japanese Patent Application Laid-Open No. Sho 63-41186 discloses that the transparency of a reversible thermosensitive recording material composed of a resin base material and an organic low molecule dispersed in the resin base material is reversibly changed. A reversible thermosensitive recording material that displays an image by contrast between a transparent part and a cloudy part is disclosed.

[0005] Also, Japanese Patent No. 2765115 discloses that
There is known a reversible thermosensitive recording material which can reversibly form a frost surface (rough surface) or a smooth surface depending on a heating temperature condition and a cooling condition after heating.

The reversible thermosensitive recording material as described above is dissolved in an organic solvent such as tetrahydrofuran (THF),
This is applied to a substrate of a recording medium such as a film, dried and cured, and used as a recording medium. The surface of the recording layer may be covered with a protective layer to protect it from physicochemical damage.

[0007] Incidentally, a liquid obtained by dissolving a heat-sensitive recording material in an organic solvent is easily absorbed by papers and the like, and it is difficult to form a coating film. Therefore, in order to provide a reversible thermosensitive recording layer on the surface of papers and other various articles, it is considered that a method of transferring a transfer sheet having a reversible thermosensitive recording layer has high versatility and is preferable.

As shown in FIG. 8, a transfer sheet B of a conventional reversible thermosensitive recording material is provided with a release agent layer 2 made of a silicone resin or the like on a release base material layer 1 and overlaid thereon. A protective layer 3 made of a suitable resin is provided, and the recording layer 4 of the reversible thermosensitive recording material overlaid thereon is protected from physicochemical damage. 8, reference numeral 5 denotes a barrier layer for isolating the recording layer 4, reference numeral 6 denotes an anchor layer for improving the adhesiveness, and reference numeral 7 denotes a transfer adhesive layer made of a heat-sensitive adhesive. I have.

[0009] Such a transfer sheet B is usually wound up in the form of a belt (tape), and the transfer layer b is transferred onto the surface of the transfer object while rewinding the formed roll.

More specifically, as shown in FIG. 8B or 8C, a heat transfer mold (stamp) 16 is formed on the back surface of the transfer sheet B (the upper surface of the release substrate layer in the figure). Is pressed, and the area to be transferred of the transfer layer b is bonded to the object 10 by heating and pressing, and then the separating substrate layer 1 is separated from the object to be transferred 10 integrally with the area to be non-transferred of the transfer layer b. Thus, the transfer layer b is transferred to the transfer object 10.
Note that reference numeral 15 in FIG. 8B indicates a guide roller.

At this time, the transfer adhesive layer 7 made of a thermoplastic resin is pressed against the surface of the transfer object 10 and heated, so that the adhesive is softened and adheres to the transfer object 10, and the reversible thermosensitive recording layer is formed. Reference numeral 4 denotes an object to be transferred 10 covered with the protective layer 3.

However, a transfer sheet of a usual reversible thermosensitive recording material is designed to withstand repetition of printing and erasing (rewriting) after transfer, and in particular, a physical layer is formed on a protective layer and other layers. Since the strength is made as high as possible, the laminate is hardly torn and has a strong so-called "strain", and it is not easy to form a clean cut surface when bonding the transfer layer.

That is, when the transfer is performed by heating and pressing with a mold called a hot stamp as shown in FIGS. 8B and 8C, the non-transfer area and the transfer area of the transfer layer b are not reliably separated. as shown in FIG. 8 (d), there is a case where a piece b ₁ at the boundary of the torn transfer layer b is adhered to the transfer zone.

When the transfer layer b is formed to be hard so that no cuts remain in the transfer area, cracks (cracks) may occur at the peripheral edge of the transfer area due to the effects of heating, pressing, tearing, bending, and the like during transfer and cutting. ) Is likely to occur.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems and to precisely transfer and cut a transfer area of a reversible thermosensitive recording material comprising a film-like laminate such as a tape. An object of the present invention is to provide a transfer sheet of a reversible thermosensitive recording material that can be transferred so that no cut ends remain when a part of the material is transferred or a crack is not generated around a transfer area.

In order to solve the above-mentioned problems, in the present invention, a transfer layer is releasably superimposed on a release substrate layer, and the transfer layer is made of a reversible thermosensitive recording material. A transfer sheet of a reversible thermosensitive recording material, comprising a laminate having a recording layer and a transfer adhesive layer, wherein a cut weakening portion is provided at a boundary between a transfer scheduled area and a non-transfer scheduled area of the transfer layer. It was done.

In the transfer sheet of the present invention configured as described above, the release substrate layer is pressed so that the transfer area of the transfer layer is adhered to the transfer object, and then the non-transfer area of the transfer layer is pressed. When detached from the object to be transferred together with the base material layer for separation, the boundary between the planned transfer area and the non-transfer planned area is completely cut by the cutting weakening part, and the transfer has a clean cut surface without a cut near the boundary part The layer adheres to the transfer material.

As a mode of the weakened portion for cutting, a cut line having a predetermined depth called half-cut or half-cut obtained by previously cutting the transfer layer while leaving all or a part of the peeling substrate layer can be adopted. .

Alternatively, as another mode of the weakening portion for cutting,
After the half cut is formed, a fold may be further formed to actively generate cracks (small cracks) along the boundary between the planned transfer area and the non-transfer planned area.

As the means for forming the above-mentioned weakened portion for cutting, a method of using a mold blade or other cutting tool, or a method of forming a half-cut line of a predetermined depth using a non-contact laser beam is adopted. You can also.

In order to solve the above problems, the following transfer method can be adopted.

That is, the transfer base layer is releasably superimposed on a tape-like release base layer, and the release base layer is pressed from the back surface by a mold, and the transfer layer is transferred to the transfer object. In the transfer method of pressing the surface, the transfer layer is formed of a laminate having a recording layer made of a reversible thermosensitive recording material and a transfer adhesive layer, and is provided at a boundary between a planned transfer area and a non-transferable area of the mold. A method for transferring a reversible thermosensitive recording material, comprising providing an acute-angled blade-shaped portion and pressing the blade-shaped portion to form a crack for cutting in a transfer layer.

In the above transfer method, when the peeling substrate layer is pressed from the back surface with the mold and the transfer area of the transfer layer is adhered to the object to be transferred, the sharp-edged edge-shaped portion provided at a key point of the mold is provided. However, the transfer layer provided with the recording layer and the transfer adhesive layer is bent at an acute angle, and a linear crack is formed at the position where the blade portion hits, that is, the transfer scheduled area of the transfer layer and the non-transfer The boundaries of the planned area are weakened or cracked. Next, when the mold and the release substrate layer are separated from the transfer object integrally with the non-transferred area of the transfer layer, the boundary between the planned transfer area and the non-transferred area is completely cut by the weakened portion for cutting, and the vicinity of the boundary portion The transfer layer having a clean cut surface adheres to the transferred material without leaving any cuts.

After the half-cut treatment, the non-transferred area may be peeled off in advance, and a transfer sheet may be left in which only the expected transfer area is left on the tape-like release substrate layer.
In this way, the transfer sheet from which the non-transfer scheduled area has been peeled off in advance can be pressed with a hot stamp larger than the shape of the planned transfer area, and at that time, only the planned transfer area can be accurately transferred.

The step of stripping the non-transferred area is performed before the pressing step using the hot stamp. However, the pressing step can be performed simultaneously and in parallel with removing the non-transferred area immediately before the pressing step. .

BEST MODE FOR CARRYING OUT THE INVENTION The release substrate layer constituting the transfer sheet of the present invention is made of a sheet such as a film or paper having releasability, and may be transparent or opaque. Also, flexibility and toughness for easy handling when peeling are required. Therefore, when a plastic film is used as the peeling substrate layer, the base material is adjusted so as to have required physical properties by, for example, blending an appropriate amount of a plasticizer.
