Abstract

PROBLEM TO BE SOLVED: To prevent troubles such as defective conveyance or insufficient cutting encountered in use due to the sticking of a pressure-sensitive adhesive to a conveying path or a sheet cutter in a printer or such as improper cutting in manufacturing due to the sticking of the adhesive to a slitter or a sheet cutter from occurring. SOLUTION: In the heat transfer image receiving sheet 110 for a seal to be taken up, a pressure-sensitive adhesive part 34 made up of a pressure- sensitive adhesive of a seal is not formed over the entire surface of the sheet 110 but a nonpressure-sensitive adhesive part 35 is formed on a side edge part in the photographic process direction, a vertical side edge part 32 in the photographic process direction and a sheet cut part. When manufacturing the sheet 110, a slitting or sheet cutting operation is performed in the nonpressure-sensitive adhesive part. The nonpressure-sensitive adhesive part is, for example, a part where the pressure-sensitive adhesive is not coated or a part where the already existing pressure-sensitive adhesive layer is turned to the nonpressure-sensitive adhesive layer using a pressure-sensitive adhesive force diminisher.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a thermal transfer image-receiving sheet for sealing and a method for producing the same.

[0002]

2. Description of the Related Art At present, a heat-sensitive melting transfer method and a heat-sensitive sublimation transfer method as thermal transfer recording methods are widely used as printers for personal computers and video printers. In particular, the thermal sublimation transfer method is suitable for printing a photograph of a person or the like taken by an electronic camera or a video camera because of its excellent density gradation expression power comparable to that of a silver halide photograph. Therefore, if an image can be formed on a sticker by thermal transfer recording, an image such as a favorite photograph can be easily used as the sticker. FIG. 14 is a sectional view of an example of a conventional thermal transfer image receiving sheet for sealing. In the figure, one seal is provided for simplification of the description. The thermal transfer image-receiving sheet for sealing 130 is
Half cut 5 from the receiving layer side to the sealing layer 4 composed of the receiving layer 1, the base sheet 2 and the adhesive layer 3 in order from the printing screen side.
The inside of the outer periphery of the half cut 5 is a seal 6, and a release sheet 7 is further adhered to the surface of the adhesive layer. In the release sheet 7, the release layer 72 formed on the release sheet substrate 71 serves as a release surface. Then, after an image is formed on the receiving layer 1 by the printer, the seal 6, which is the portion of the seal layer 4 surrounded by the half cut 5, is peeled off, and the seal can be attached to an arbitrary place. The heat transfer image-receiving sheet for sealing 130 shown in FIG.
Is a sheet for heat-sensitive sublimation transfer recording having a receiving layer.

[0003]

However, in the conventional thermal transfer image receiving sheet for sealing, since the adhesive layer is applied and formed on the entire surface, when the image receiving sheet is transported in the printer, the transport path in the printer is used. The adhesive of the adhesive layer exposed on both sides in the width direction of the image receiving sheet adheres to and accumulates on the guide rollers and sheet guides of the image receiving sheet. there were. That is, FIG. 15 is a conceptual diagram showing an example of a transport mechanism of the sealing thermal transfer image receiving sheet in the printer. In the printer illustrated in FIG.
The sealing thermal transfer image-receiving sheet 130 is conveyed while being nipped by the grip roller 220 which is connected to a driving source (not shown) and is driven to rotate. The heat transfer image-receiving sheet 130 for sealing shown in FIG. 3 is unwound from the take-up 140 and is adjusted in the width direction through the guide roller 230, the guide plate 240, and the width-direction regulating guide roller 250 in this order. After a desired image is printed by passing between the rollers 270, the image is conveyed to the next portion where sheet cutting or the like is performed via the nip roller 210 and the grip roller 220. The width direction regulating guide roller 250 is provided with rings 251 on both left and right sides, leaving a portion corresponding to the sheet width at the center in the axial direction, and regulates the width direction position on the inner side surface of the ring 251. The guide plate 240 has a guide groove 241 that forms a recess corresponding to the sheet width along the conveyance direction for regulating in the width direction, as shown in the external view of FIG. 16. Then, as the heat transfer image-receiving sheet for sealing is conveyed together with the guide roller 230 and the guide roller 250 for regulating the width direction,
The widthwise position is regulated by being guided by the guide groove 241. In this way, by adjusting the conveying path and the guide roller to the width of the sealing thermal transfer image receiving sheet, the control is performed so that the sealing thermal transfer image receiving sheet does not undulate when being transported. In such a printer, the transport path and the guide roller (the guide groove 241 of the guide plate 240 in the drawing)
251 of side, width direction regulating guide roller 250 ring 251
Side of the thermal transfer image-receiving sheet for sealing is in contact with the side surface of the sealing heat transfer image-receiving sheet, so that the adhesive bleeding from the side surface is likely to adhere. As a result, the transport route is narrowed by sediment,
The thermal transfer image-receiving sheet for a seal was stuck, resulting in transport failure. Also, even in the case of a transport mechanism without a guide plate or a width direction regulating guide roller, if the tension applied to the thermal transfer image-receiving sheet for sealing during transport is strong, the adhesive is pushed out from the front and rear and left and right side surfaces, Similarly, a transport failure occurred. Although the heat transfer image-receiving sheet for sealing in FIG. 1 is wound up, the problem caused by the adhesive layer exposed from the side surface in the printing direction side also occurs in a printer that prints a cut sheet.

[0004] Further, in the heat transfer image receiving sheet for sealing in a winding form, after an image is formed, the sheet is cut by a sheet cutter mechanism provided in the printer. At that time,
In some cases, the adhesive adhered to the cutter, resulting in poor cutting of the cutter, and the heat transfer image-receiving sheet for sealing stuck to the cutter, resulting in poor conveyance.

[0005] Further, even when producing a heat transfer image-receiving sheet for sealing, a slit-shaped heat transfer image-receiving sheet having an arbitrary width can be cut from a wide-width wound heat transfer image-receiving sheet for sealing. Adhesive adheres to the slitter or cutter when cutting the sheet in order to cut the heat transfer image-receiving sheet from the image receiving sheet to an arbitrary width and length. And caused transport failures in the manufacturing equipment. Therefore, as a solution, silicone was applied to the cutter, or a fluororesin processing was applied to a contact portion in the printer, but a sufficient effect was not obtained.

[0006]

In order to solve the above-mentioned problems, a heat transfer image-receiving sheet for a seal according to the present invention has been developed.
By partially forming the adhesive portion by the adhesive layer, a non-adhesive portion having a weak adhesive portion having a lower adhesive strength than the adhesive portion or a non-adhesive portion having no adhesive force, the sheet is in a winding mode. In the sheet-cut sheet-like form, the sheet cutting section is provided at an end along the printing direction side or an end along a side perpendicular to the printing direction. As a result, the adhesive layer is not exposed particularly from the sheet side surfaces at both ends in the width direction along the printing direction of the printer, and the sheet side surfaces before and after the printing direction, so that adhesion of the adhesive to the printer transport path can be prevented. Further, when the sheet is cut from the winding mode after printing by the printer, the sheet cut portion is a non-adhesive portion, so that adhesion of the adhesive to the cutter can be prevented. In addition, even in a single sheet, the adhesive layer is not exposed on the sheet side at the left, right, front and rear ends of the printing direction side and the vertical side in the printing direction, and the adhesive does not protrude by pressing. Prevents adhesion. The non-adhesive part is an unformed part (non-adhesive part) formed by applying or printing an adhesive, or a part in which the adhesive layer is made non-adhesive (weak or non-adhesive) by an adhesive force reducing agent, or a sheet. It is configured as a non-adhesive part (weak or non-adhesive) at the end or as a non-adhesive layer (weak or non-adhesive) formed of an adhesive force reducing agent formed on the side surface of the sheet.

In the method for producing a thermal transfer image-receiving sheet for a seal according to the present invention, at least a receiving layer is formed on one surface of a substrate sheet, and the other surface of the substrate sheet or the release surface of the release sheet is removed. After forming the adhesive layer on the surface, the base sheet and the release sheet having the adhesive layer formed on any one of the sheets were bonded via the adhesive layer, slit into a predetermined width, and then wound. In the method of forming a sheet, when forming the adhesive layer, the adhesive layer is partially formed except for one or both of the slit portion and the sheet cut portion, so that the slit portion has a weak adhesive or non-adhesive non-adhesive. If the adhesive portion is formed, it is possible to prevent the adhesive from adhering to the slitter at the time of manufacture, and to obtain a heat transfer image-receiving sheet for sealing in which the adhesive is not adhered even in the printer. If a non-adhesive portion is formed in the sheet cut portion, a thermal transfer image-receiving sheet for sealing can be obtained in which the adhesive does not adhere to the cutter when the sheet is cut by the printer. Further, another manufacturing method of the present invention forms at least a receiving layer on one surface of a base sheet, and forms an adhesive layer on the other surface of the base sheet or any surface of the release surface of the release sheet. Thereafter, the base sheet and the release sheet having the adhesive layer formed on one of the sheets are bonded together via the adhesive layer, slit and cut to a predetermined width and a predetermined length, and then a sheet-like sheet. When forming the adhesive layer, when forming one or both of the slit portion or the sheet cut portion as a weakly adhesive or non-adhesive non-adhesive portion, partially forming the adhesive layer other than the non-adhesive portion Therefore, if a non-adhesive portion is formed in the slit portion, the adhesive is prevented from adhering to the slitter in the manufacturing process. Adhesive sticks to the cut cutter To prevent. And
A heat transfer image-receiving sheet for a seal to which no adhesive is attached even in the printer. Further, in the production method of the present invention, as one of the methods for forming the non-adhesive portion, the adhesive layer formed including the non-adhesive portion is partially applied with an adhesive force reducing agent to partially form the adhesive layer. To a non-adhesive part by weakly or non-adhesively. As a result, since the formation of the adhesive layer can be performed by one unit of the printing machine or the coating machine, the conventionally used printing machine or the coating machine can be used as it is, and there is an advantage that the manufacturing time is the same as the conventional one.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a thermal transfer image-receiving sheet for a seal according to the present invention will be described with reference to the drawings. First, the pattern shapes of the non-adhesive portion and the adhesive portion will be described. FIG. 1 is an external view illustrating a pattern of a non-adhesive portion and an adhesive portion with an adhesive layer of a heat transfer image receiving sheet for a seal 110 in a rolled form as one form of the thermal transfer image receiving sheet for a seal of the present invention. FIG. In order to make the description easy to understand, the layer configuration of the receiving layer and the base sheet, the half cut, and the like are not shown. Then, FIG. 1 (A)
The non-adhesive portion 35 was formed in a band shape on the both sides 30 in the printing direction without forming the adhesive portion 34 by the adhesive layer at the side edge 30 in the printing direction (the end along the side in the printing direction) 30. It is a form. FIG. 1B shows a non-adhesive portion 3 on the sheet cut portion 32.
5 is formed in a band shape in the width direction, and the non-adhesive portion 35 is left to form the adhesive portion 34. FIG. 1C shows both sides 30 in the printing direction and the sheet cut portion 32 on both sides. This is a mode in which a non-adhesive portion 35 is formed and an adhesive portion 34 is formed on the remaining portion. In the embodiment of FIG. 1A, an effect of preventing a conveyance failure due to the adhesion of the adhesive to the conveyance mechanism of the printer can be obtained. In the embodiment shown in FIG. 1B, an effect of preventing the adhesive from adhering to the sheet cutting mechanism of the printer, resulting in poor cutting of the cutter, and preventing the heat transfer image-receiving sheet for sealing from adhering to the cutter to cause a conveyance failure. Is obtained.
In the form of FIG. 1C, the effects of both FIGS. 1A and 1B are obtained, and this is the most preferable form. Note that the position of the sheet cut section 32 is,
The position of the non-adhesive part 35 provided in accordance with the size of the image to be formed is provided. For example, the size is adjusted to the size of an image (one screen) that can be formed by one printing.

The above description has been given of the heat transfer image-receiving sheet for sealing in the winding form. However, the heat transfer image-receiving sheet for sealing of the present invention may be a sheet cut in advance to a predetermined size. FIG. 2 shows an example of a single-sheet, that is, a thermal transfer image-receiving sheet for sealing 120 of the present invention in the form of a cut sheet (this figure also mainly shows a non-adhesive portion, an adhesive portion, and the like as in FIG. 1). FIG. 2A shows both edges 3 in the printing direction.
In this embodiment, the non-adhesive portion 35 is formed in a strip shape, and the remaining portion is formed as an adhesive portion 34, which is effective in preventing trouble during transport by the printer. FIG. 2B shows a form in which a non-adhesive portion 35 is formed in a band shape at an end portion of a vertical side in the printing direction (an end portion along a side perpendicular to the printing direction) 31 and the remaining portion is an adhesive portion 34. Yes, it is particularly effective in preventing trouble during sheet cutting during manufacturing, and can increase production efficiency. FIG. 2C shows a non-adhesive portion 35 at each end of the printing direction side edge 30 and the printing direction vertical side edge 31, that is, an end along the entire circumference, that is, a frame. This is a form in which the adhesive part 34 is formed in the form of a stick, and is effective in preventing troubles both during transportation and during manufacture, and is the most preferable form in a single-wafer form.

The width of the non-adhesive portion 35 provided at the edge along the periphery of the sheet such as the printing direction side and the printing direction vertical side is as follows:
It may be appropriately selected according to the pressure-sensitive adhesive, the seal layer, the material of the release sheet, and the transport mechanism of the printer, but if it is too wide, the seal tends to peel off from the release sheet before use, or the strength of the sheet side surface is weak. It becomes easy to tear. Further, when the non-adhesive part is an unformed part formed by coating the adhesive layer or the like, it is not preferable because the adhesive sticks out from the side even if the width of the non-adhesive part is too narrow. Normally, the width of the non-adhesive portion is about 1 mm to 20 mm. The same applies to the width of the non-adhesive layer 35 provided in the sheet cut portion 32.

Next, the method for producing the thermal transfer image-receiving sheet for a seal of the present invention is as follows. First, a receiving layer is formed on one side of a base sheet as a support for the seal layer via an intermediate layer or the like as appropriate. Then, an adhesive layer may be partially formed on the other surface of the base sheet, and a release sheet may be attached to the adhesive layer surface. Alternatively, the adhesive layer may be partially formed on the release sheet side instead of the seal layer side, and the release sheet on which the adhesive layer is formed and the base sheet on which the receiving layer or the like is formed may be bonded.

In order to partially form the adhesive layer and form the adhesive portion and the non-adhesive portion, the adhesive layer may be formed in a pattern from the beginning on the base sheet (in this case, the non-adhesive portion). When a weak adhesive portion is used, a weak adhesive layer to be a weak adhesive portion is also formed in a pattern), and after forming an adhesive layer on the entire surface,
A process of partially weakening or eliminating the adhesive force may be performed, and as a result, the adhesive layer may be formed in a pattern shape,
There is no particular limitation.

As a method of forming the adhesive layer in a pattern from the beginning, a printing or coating method capable of forming a pattern, such as gravure printing or gravure reverse coating, is used.
According to this method, the formation of the adhesive layer can be performed by one unit of a printing machine or a coating machine, and thus a conventionally used printing machine or coating machine can be used as it is. Also, there is an advantage that the manufacturing time is not different from the conventional one. In addition, as a method of forming a weak adhesive layer as a non-adhesive portion in a pattern, a method in which the coating thickness is reduced only in that portion can be formed in one unit simultaneously with the adhesive layer. When the weak adhesive layer is applied later, it can be formed by spray coating or the like.

As a method of forming a non-adhesive portion as a weakly adhesive portion or a non-adhesive portion by partially weakening or eliminating the adhesive force after forming an adhesive layer on the entire surface, first, as shown in FIG.
First, an adhesive layer is formed on the entire surface. At this point, the entire surface becomes the adhesive portion 34. A coating method such as a roll coating method or an extrusion method can be used for forming the entire surface of the adhesive layer. afterwards,
If an adhesive force reducing agent for eliminating the adhesive force is partially formed on the portion where the adhesive force is to be eliminated and the non-adhesive portion 35 is to be formed, the remaining portion becomes the final adhesive portion 34, and as a result, the adhesive layer is formed into a pattern. Can be formed.

As the adhesion reducing agent, those which react with the adhesive of the adhesive layer and reduce the adhesion itself are used. In this case, a reaction-type pressure-sensitive adhesive is used in order to react with the pressure-sensitive adhesive reducing agent. For example, it is a two-component curable adhesive such as an acrylic adhesive. As the adhesive force reducing agent for the two-part curable adhesive, for example, a highly reactive curing agent such as a chelating agent, isocyanate, or epoxy resin can be used. Then, after the application of the adhesive layer, an adhesive force reducing agent is applied to a desired portion by a forming means such as an application means such as a spray to reduce the adhesive force of the adhesive itself constituting the adhesive layer. As a result, the adhesive layer in the portion to which the adhesive force reducing agent has been applied loses or loses the adhesive force, and becomes a non-adhesive portion having a weak adhesiveness or a non-adhesiveness. FIG. 4 is a cross-sectional view showing a state in which an adhesive force reducing agent is applied to a desired portion of the adhesive layer 3 so that the adhesive layer itself becomes non-adhesive and a non-adhesive portion 35 is formed. In addition,
In the same figure, the adhesive layer 3 is applied and formed on a release sheet 7,
FIG. 3 is a diagram in a case where an adhesive force reducing agent is applied to a main part of an adhesive layer 3. The adhesive force reducing agent applied by application or the like may partially remain on the surface of the adhesive layer, but penetrates into the adhesive layer and renders the interior of the adhesive layer non-adhesive. In the method in which the adhesive layer is partially formed in a pattern form from the beginning, the adhesive layer is likely to bleed or protrude on its outer periphery, but in the method using the adhesive force reducing agent, substantially, The adhesive layer is easily formed in a pattern. In the other method, the step between the unformed portion and the formed portion of the adhesive layer may be propagated to the adjacent image receiving sheet in the wound state and appear on the printing screen. It doesn't matter.

Further, as the adhesive force reducing agent, a material that covers the adhesive surface of the adhesive layer, eliminates the adhesive force on the surface of the adhesive layer, and forms a non-adhesive non-adhesive portion can be used. In this case, since the adhesiveness inside the adhesive layer is kept as it is, in order to impart non-adhesiveness to the side surface of the sheet, it is preferable to put the heat transfer image-receiving sheet for sealing in a wound state and apply an adhesive force reducing agent to the side surface of the sheet. In this case, the non-adhesive layers on the side of the overlapped sheet are connected vertically and become an integrated layer, but if the thickness of the non-adhesive layer is appropriately thinned, Since the non-adhesive layers connected to each other are easily separated from each other, there is no hindrance to the use of winding. In the case of a single sheet, the sheet may be applied after being applied to the side surface of the sheet in a stacked state. In addition, the method of applying the adhesive force reducing agent to the side surface of the image receiving sheet can also be used with the adhesive force reducing agent for eliminating the adhesive force to the inside of the adhesive layer as described above. As the adhesive force reducing agent for reducing the adhesive force on the surface of the adhesive layer, a non-adhesive resin dissolved or dispersed in a suitable solvent such as an organic solvent or water can be used. Specific examples include resins such as cellulose, acrylic resin, polyester, polyurethane, vinyl chloride-vinyl acetate copolymer, polypropylene, and polyethylene, ultraviolet curable resins, and electron beam curable resins. By applying an adhesive force reducing agent composed of these resins to the adhesive layer (side) surface of the sheet side by spraying or the like so that the thickness becomes 1 μm or more after solidification, a non-adhesive resin layer is formed on the adhesive layer surface. It can be a non-adhesive part. If the thickness is too thick, the continuous non-adhesive resin layer on the sides of the sheet will not break,
It is preferable that the thickness be 5 μm or less. In addition, when the adhesive force reducing agent is applied to the sheet side surface, so that the solvent component of the adhesive force reducing agent does not penetrate between the sheets stacked by sheet or by winding.
An additive such as silica may be added to the tackifier as a thixotropic agent for imparting thixotropic properties. Also, when making the side of the sheet non-adhesive,
Since it is not necessary to make the inside of the adhesive layer non-adhesive,
An aqueous solvent that does not swell the adhesive layer may be used.

Incidentally, the non-adhesiveness of the non-adhesive portion is as follows.
In the case of slitting or sheet cutting, it is preferable that the adhesive layer is provided to the inside in the thickness direction, and for the purpose of preventing transport trouble in the printer, it is preferable that the adhesive layer is provided on the side surface of the thermal transfer image receiving sheet for sealing. .
In the cross-sectional view of FIG. 4, the non-adhesive portion 35 made of the adhesive force reducing agent is formed in the thickness direction, but if the left and right side surfaces in the drawing are the sheet side surfaces, the sheet side surfaces also have non-adhesiveness as the non-adhesive portion. The appearance is also shown. FIG. 5 shows a cross-sectional view of an example of the thermal transfer image-receiving sheet 100 for sealing of the present invention, in which a non-adhesive portion is provided on the side surface of the sheet as a non-adhesive layer 36 made of an adhesive force reducing agent. This drawing is a conceptual diagram in which one half-cut seal is provided in the drawing width direction of the image receiving sheet for explanation. Except for having the non-adhesive layer 36 on the side surface of the sheet, the layer configuration, reference numerals, and the like are the same as those in FIG.

As can be seen from the description so far, the term "non" of the non-adhesive portion in the present invention means a non-adhesive portion where the adhesive layer is not originally formed, and the adhesive force of the adhesive layer has disappeared. Non-adhesive part lost in the adhesive layer, weak adhesive part where the adhesive strength of the adhesive layer decreases and some adhesive strength remains, part where the adhesive layer is covered with a weak adhesive or non-adhesive non-adhesive layer, weak from the beginning Any part of weak adhesion due to the adhesive layer formed from an adhesive adhesive.

Then, according to the above or the above method,
For example, after forming a non-adhesive part and an adhesive part on a main part on the side of the base sheet on which the release sheet or the receiving layer is formed, the release sheet and the base sheet are bonded together on the adhesive layer surface. afterwards,
Slitting is performed on an arbitrary width, and the sheet is wound up as a roll or cut into sheets of an arbitrary width and length as a cut sheet. When the thermal transfer image-receiving sheet for sealing is manufactured by the above method, the adhesive does not adhere to the slitter or cutter at the time of slitting or sheet cutting, so that it can be efficiently manufactured without becoming difficult to cut or causing conveyance failure.
When manufacturing a heat transfer image-receiving sheet for sealing wound at a desired width from a wide winding of the heat transfer image-receiving sheet for sealing, if the slit portion is a non-adhesive portion, the sheet shown in FIG. Fig. 1 (B) if only the cut part is non-adhesive part
If both the slit portion and the sheet quad portion are non-adhesive portions, the shape shown in FIG. 1C is obtained. In addition, when a sheet of heat transfer image-receiving sheet of desired length and width is manufactured from winding of the sheet for heat-transfer image for seal, if only the slit portion is a non-adhesive portion, the sheet shown in FIG. If only the sheet cut part is the non-adhesive part, FIG.
In the case of FIG. 2B, if both the slit portion and the sheet quad portion are non-adhesive portions, the structure of FIG. 2C is obtained. In this case, the printing direction is a case where the printing direction is the longitudinal direction of the winding. In addition, when a cut sheet is obtained, a large-sized cut sheet multi-faced from winding may be once created, and cut into a final size cut sheet. In this case, the slit part may be a sheet cut part. When the first winding width is the width of one cut sheet, there is no slit portion.
Depending on the pressure-sensitive adhesive, the seal layer, the material of the release sheet and the transport mechanism of the printer, if there is a particularly non-adhesive non-adhesive portion on the outer periphery of the seal, the seal may be removed before use, although it depends on the width. The sheet may be peeled off or the strength of the side of the sheet may be weakened, causing the sheet to tear or break. In such a case, as the non-adhesive portion, a weak adhesive portion may be provided instead of the non-adhesive portion having no adhesive force. The weakly adhesive portion is formed of an adhesive such as an acrylic adhesive which has a very low flowability such that the adhesive does not protrude from the end surface of the image receiving sheet, or a coating amount of the adhesive of 1 g / m2. The problem of the present invention can be solved by reducing the amount to ^{2 to} 8 g / m ² . Although the weak adhesive portion is not non-adhesive, the adhesive force is made weaker than the adhesive portion, so that an effect of preventing the adhesive from adhering to the slitter, the cutter, the sheet conveying mechanism, and the like can be obtained. Further, the weak adhesive layer to be the weak adhesive portion is obtained by forming the adhesive layer in a pattern and then forming the weak adhesive layer in a pattern.

When an image is formed, a dye layer of three or more colors is usually superimposed on a receptor layer as a thermal transfer sheet. However, during image formation, a thermal transfer image receiving sheet for sealing is used so that each color image is not shifted. It is preferable to provide a detection mark in a region where no image is formed on the back surface or the front surface. In particular, in the case of a thermal transfer image receiving sheet for sealing as shown in FIGS. 1B and 1C, an image may be formed on a non-adhesive portion.
A detection mark is particularly necessary. FIG. 6 shows an example in which a hole is formed as a detection mark 8 for each screen in the thermal transfer image-receiving sheet 110 for winding seal. In the figure, a total of 16 stickers 6 each of which is four in the printing direction and the width direction constitute one screen in which an image can be formed by one thermal transfer recording, and a top portion in each area of one screen, An elliptical hole that is long in the width direction is formed as the detection mark 8. In the case of punching, it is preferable that the punched portion is also a non-adhesive portion. Note that the detection mark may be provided on the back surface or the front surface of the image receiving sheet by printing or the like without perforation, and the detection mark may have any shape.

FIGS. 5 and 6 show the outer periphery of the seal 1.
It is preferable to make the half cut 5 as shown in FIG. The half-cut processing is performed by a cutter or a laser at the time of producing the heat transfer image-receiving sheet for sealing. Further, as in the thermal transfer image-receiving sheet for sealing 100 shown in FIG. 7, a half-cut 5 for inserting the half-cut to the adhesive layer 3 of the seal layer 4 and a shallow half-cut 51 for stopping halfway in the base sheet 2 of the seal layer 4 are provided. It is preferable that the seal is provided on a part of the outer periphery of the seal 6 because the seal does not peel off during printing. Half cut 5
In order to provide the shallow half cut 51, for example, a cutter whose position is adjusted or a laser whose output or irradiation time is adjusted is used.

When the heat transfer image-receiving sheet for sealing of the present invention is used as a sheet-cut sheet, it may be necessary to use an image such that the outer periphery of the seal is half-cut or a frame indicating the image forming position is provided. In the case where the forming position is determined, if the mounting direction to the printer is wrong, the image forming position and the actual image may be shifted. Therefore,
It is preferable to apply one or more of the following methods shown in FIGS. 8 to 10 to the (sheet-wise) sealing thermal transfer image-receiving sheet 120.

In the method shown in FIG. 8, the positions of a plurality of image forming units 61 arranged in the sheet surface are symmetrical in the left-right and front-back directions (with respect to the printing direction). In the case of the seal 6 surrounded by the half cut, the image forming unit 61
The shape 1 is also symmetrical, for example, left and right and front and back. As a result, even if the mounting direction to the printer is incorrect, the position of the image forming unit 61 is the same, and the image is not formed with a shift.

In the method shown in FIG. 9, when the image is received on the back or front side of the image receiving sheet, direction indicating information such as characters and symbols indicating directions such as a mounting direction, a conveying direction and a printing direction is formed. . In addition, on the printer side, similarly to the cassette in which the image receiving sheet is loaded and the surrounding area, the mounting direction,
It is preferable to form characters, symbols, and the like indicating the transport direction or the printing direction. FIG. 9 shows an example in which many arrows are formed on the entire surface. In addition, if the characters and symbols to be formed are not a single screen unit but an endless continuous pattern as a whole, the sheet cutting position accuracy can be loosened or arbitrarily manufactured when a sit cart is performed from winding. In addition, when it is formed on the surface having the receiving layer, it may be formed with an adhesive ink such as an ultraviolet curable ink at a position where printing is not hindered.

In the method shown in FIG. 10, a detection mark 8 is provided by printing or the like on the back or front surface of the image receiving sheet, and if the mounting direction is wrong, it is detected by a sensor of the printer so as not to print. When forming on the surface with the receiving layer,
What is necessary is just to form in the position which does not interfere with printing with ink which has adhesiveness, such as ultraviolet curable ink. The shape of the detection mark is arbitrary. Further, as long as it is asymmetrical in front and rear, right and left, it may be provided by drilling a hole or the like.

Next, the layer structure, the material of each layer and the like of the heat transfer image-receiving sheet for sealing of the present invention having the non-adhesive portion as described above will be described with reference to the drawings. Figure 5 already
7 and FIG. 7 exemplify a layer configuration, but FIG. 11 shows an example in which a laminate is used for a base sheet. The thermal transfer image-receiving sheet 1 for sealing according to the present invention shown in the sectional view of the main part of FIG.
00 is an antistatic treatment layer 9,
A receiving sheet 1, a base sheet 2 in which a foamed resin film 21 and a non-foamed resin film 22 are laminated via an adhesive layer 23,
And a sealing sheet 4 composed of an adhesive layer 3 and a release sheet substrate 7.
1 has a layer configuration in which a release sheet 7 having a release layer 72 is attached. A half cut 5 of the seal layer 4 extending to the adhesive layer 3 and a shallow half cut 51 of the seal layer 4 stopped in the middle of the base sheet 2 are formed on the outer periphery of the seal 6.

(Receiving Layer) First, as a material for forming the receiving layer 1, for example, a polyolefin resin such as polypropylene, a vinyl chloride-vinyl acetate copolymer, ethylene-
Halogen polymers such as vinyl acetate copolymers and polyvinylidene chloride, polyester resins such as polyvinyl acetate and polyacrylate, polystyrene resins, polyamide resins, and olefins such as ethylene and propylene with other vinyl monomers Copolymer resin, ionomer,
Cellulose-based resins such as cellulose diacetate and polycarbonate-based resins are exemplified. Among them, particularly preferred are a polyester resin, a vinyl chloride-vinyl acetate copolymer, and a mixture thereof.

A release agent may be mixed with the above-mentioned resin in the receiving layer in order to prevent fusion with the dye layer of the sublimation type thermal transfer sheet during image formation or to prevent a decrease in printing sensitivity. it can. Preferred release agents for mixing use include silicone oils, phosphate-based surfactants,
Examples thereof include a fluorinated surfactant, and among them, silicone oil is preferable. As the silicone oil,
Epoxy modification, vinyl modification, alkyl modification, amino modification, carboxyl modification, alcohol modification, fluorine modification,
Modified silicone oils such as alkyl aralkyl polyether-modified, epoxy / polyether-modified, and polyether-modified are preferred.

One or more release agents are used. The amount of the release agent to be added is preferably 0.5 to 30 parts by weight based on 100 parts by weight of the resin for forming the receiving layer. Outside of this range, problems such as fusion between the sublimation type thermal transfer sheet and the receptor layer of the thermal transfer image receiving sheet for sealing or reduction in printing sensitivity may occur. By adding such a releasing agent to the receiving layer, the releasing agent bleeds out on the surface of the receiving layer after transfer, and a release layer is formed on the surface. In addition, these release agents may be separately formed on the receiving layer without being added to the resin for forming the receiving layer.

The receiving layer is formed by dissolving a resin as described above and a necessary additive such as a release agent as appropriate on the surface of a base sheet such as a foamed resin film in a suitable organic solvent to form a solution. Alternatively, it is formed by applying a dispersion prepared by dispersing in an organic solvent or water as a coating liquid by a conventionally known appropriate coating method, followed by drying. In forming the receiving layer, a white pigment, a fluorescent whitening agent, or the like can be added for the purpose of improving the whiteness of the receiving layer to further enhance the clarity of the transferred image. Although the thickness of the receiving layer may be arbitrary, it is generally 1 to 50 μm (after drying).

Although such a receiving layer is preferably a continuous coating, it may be formed as a discontinuous coating using a resin emulsion or a water-soluble resin or a resin dispersion. Further, a conventionally known antistatic agent may be coated on the receiving layer in order to improve the transport stability of the printer. The antistatic agent forms an antistatic treatment layer on the receiving layer.

In the formation of the receiving layer, a release sheet may be provided on the base sheet before lamination, or the base sheet and the release sheet may be provided on the base sheet side after lamination. In the case where the base sheet is formed of a laminate, for example, the foamed resin film and the non-foamed resin film may be provided on a foamed resin film before laminating the foamed resin film and the non-foamed resin film. May be provided on the surface of the foamed resin film of the base sheet configured as described above.

(Base Sheet) The base sheet 2 serving as a support for the seal layer may be a conventionally known base sheet.

0 μm), E-60 manufactured by Toray Industries, Inc. (thickness: 50 μm)
A foamed polyethylene terephthalate film or the like is preferably used. In addition, by using a laminate of these foamed film and a non-foamed film as the base sheet, the printing density is improved due to the cushioning property of the foamed film, thereby improving the color density and improving the quality of image formation. And the rigidity (waist) of the non-foamed film prevents the seal from being folded when the seal is peeled off. A preferred lamination structure is a structure in which the receiving layer side is a foamed film and the adhesive layer side is a non-foamed film.

The film useful as the non-foamed film is a non-foamed film such as polyethylene terephthalate, polyethylene and polypropylene, and any conventionally known non-foamed resin film can be used. Preferably, the thickness is in the range of about 10-50 μm. If the thickness is too small, the stiffness is weakened, curling is likely to occur due to heat shrinkage during printing, and folds are likely to occur on the seal when peeling off the seal. Further, even when the thickness is too large, curling due to heat setting at the time of printing tends to occur. An example of a preferable non-foamed film is, for example, Lumirror S-1 manufactured by Toray Industries, Inc.
Polyethylene terephthalate film (thickness 12)
μm). Further, as a useful foamed resin film, a conventionally known foamed resin film such as a foamed polypropylene film or a foamed polyethylene terephthalate film can be used. In particular, a foamed polypropylene film is preferable because it has excellent cushioning properties and heat insulation properties, and can uniformly and efficiently transfer the dye to the receptor layer when pressed against a thermal head. The thickness of these films is 30 to
It is preferably about 60 μm. Preferred examples include, for example, Toyopearl SSP4 manufactured by Toyobo Co., Ltd.
255 (thickness 35 μm) and Toyopearl P4256 (thickness 60 μm).

As a method of laminating the non-foamed film and the foamed resin film, for example, dry lamination, non-solvent (hot melt) lamination,
Conventionally known lamination methods such as EC lamination can be used, but preferred methods are dry lamination and non-solvent lamination. Examples of an adhesive suitable for non-solvent lamination include Takenate A-720L manufactured by Takeda Pharmaceutical Co., Ltd., and examples of an adhesive suitable for dry lamination include:
Takerac A969 / Takenate A-5 (3/1) manufactured by Takeda Pharmaceutical Co., Ltd. and the like. The amount of these adhesives, coating weight of about 1-8 g / m ² with (solids), preferably used in an amount of 2 to 6 g / m ^2.

(Adhesive Layer) The adhesive layer 3 can be formed by using any of a conventionally known solvent-based and water-based adhesive. Examples of the adhesive include vinyl acetate resin, acrylic resin, vinyl acetate-acryl copolymer, vinyl acetate-vinyl chloride copolymer, ethylene-vinyl acetate copolymer, polyurethane resin, natural rubber, chloroprene rubber, and nitrile. Synthetic rubber such as rubber can be used. When reacting with the adhesive force reducing agent, a reactive adhesive such as a two-component mixed type is used among them. The coating amount of the pressure-sensitive adhesive is generally about 8 to 30 g / m ² (solid content). The pressure-sensitive adhesive is coated on a release sheet by a conventionally known method, that is, a method such as gravure coating, gravure reverse coating, or roll coating. Apply and dry to form an adhesive layer. The adhesive strength of the adhesive layer is 100 to 1,70 in a 180 ° peeling method according to JIS Z0237.
It is desirably in the range of 0 g, preferably in the range of 700 to 1,400 g. When forming an adhesive layer on the above-mentioned base sheet or the following release sheet, it is preferable to select and use the above-mentioned adhesives so that the peel strength is in the above-mentioned range.

(Release Sheet) The release sheet 7 protects the adhesive layer of the seal so as to be releasable, and is obtained by subjecting various kinds of papers, plastic films and the like to a release treatment. And a release layer 72, and various known release sheets can be used. Examples of the plastic film include a polyethylene film, a polyester film such as a polyethylene terephthalate film and a polyethylene naphthalephthalate film, a non-stretched polypropylene film, a biaxially stretched polypropylene film, a polyamide film, a polystyrene film, a polyvinyl chloride film, and a polyvinylidene chloride film. ,
Various films such as an ethylene-vinyl alcohol copolymer film, a polycarbonate film, a fluororesin film, and a polymethyl methacrylate film are exemplified. The release treatment is not particularly limited, but a resin or a release agent having a release effect is applied. The thickness of the release sheet is about 2
It is in the range of 0-100 μm, preferably 35-75 μm. Examples of the release layer 72 include various waxes such as silicone wax, silicone resin, fluorine resin, acrylic resin, polyurethane resin, polyvinylpyrrolidone, and polyvinyl alcohol. A thickness of about 0.05 to 5 μm is sufficient.

(Slip Layer) A slip layer (not shown) can be appropriately provided on the back side of the release sheet constituting the thermal transfer image-receiving sheet for sealing in order to prevent double feed at the time of paper feeding by the printer. As the slip layer, various fine particles and silicone are used alone or as a mixture of known resins such as butyral resin, polyacrylate, polymethacrylate, polyvinylidene chloride, polyester, polyurethane, polycarbonate, and polyvinyl acetate. Can be used.

The thermal transfer image-receiving sheet for a seal of the present invention will be further described below with reference to examples and comparative examples. Unless otherwise specified, “parts” means “parts by weight”.
The ratio is based on weight.

Example 1 A thermal transfer image-receiving sheet for sealing having a layer structure shown in FIG. 11 was prepared as follows. First, a foamed polypropylene film (Mobil, M
W846, thickness 35 μm, width 1000 mm) was coated and dried with a receiving layer having the following composition so that the coating amount was 4 g / m ² (when dried, the same applies hereinafter).

Receiving layer Vinyl chloride-vinyl acetate copolymer (# 1000A, manufactured by Denki Kagaku Kogyo KK) 40 parts Polyester (Vylon 600, manufactured by Toyobo Co., Ltd.) 40 parts Vinyl chloride-styrene-acrylic copolymer (Dencarak # 400A, manufactured by Denki Kagaku Kogyo Co., Ltd.) 20 parts Vinyl-modified silicone (X-62-1212, manufactured by Shin-Etsu Chemical Co., Ltd.) 10 parts Catalyst (CAT-PLR-5, Shin-Etsu Chemical Co., Ltd.) 5 parts Catalyst (CAT-PL-50T, manufactured by Shin-Etsu Chemical Co., Ltd.) 6 parts Methyl ethyl ketone / toluene = 1/1 400 parts

Next, an adhesive having the following composition is applied to the surface of the foamed polypropylene film on which the receiving layer is not formed,
A 25 μm-thick (non-foamed) transparent polyethylene terephthalate film (T-60, manufactured by Toray Industries, Inc.) was attached to the coating surface.

Adhesive Urethane resin (Takelac A-969V, manufactured by Takeda Pharmaceutical Co., Ltd.) 30 parts Isocyanate curing agent (Takenate A-5, manufactured by Takeda Pharmaceutical Co., Ltd.) 10 parts Ethyl acetate 80 parts

A pressure-sensitive adhesive having the following composition was applied to the entire surface of the other side of the laminated polyethylene terephthalate film so as to have a coating amount of 15 g / m ^2.
The adhesive layer was formed by heating and drying for 5 minutes.

Adhesive Acrylic copolymer (SK Dyne 1310L, manufactured by Soken Chemical Co., Ltd.) 48 parts Epoxy resin (curing agent E-AX, manufactured by Soken Chemical Co., Ltd.) 0.36 parts Ethyl acetate 51.64 parts

Next, as shown in FIG. 12, an adhesive force reducing agent was partially applied on the surface of the adhesive layer in the form of a plurality of strips so that the strip-shaped slits 34 in the longitudinal direction became non-adhesive portions 35. The adhesive force reducing agent was formed as a non-adhesive portion by forming an 8 mm wide portion along both ends of the long sheet material and nine strips at a regular interval of 6 mm width therebetween. On the other hand, a transparent polyethylene terephthalate film having a thickness of 38 μm (Toray Industries, Inc.)
Prepared), and a release layer having the following composition was applied on one side at an application amount of 0.2.
g / m ² , at 130 ° C. for 30 seconds,
It was dried by heating to obtain a release sheet. Thereafter, the release layer forming surface and the above-mentioned adhesive layer were overlapped and laminated.

Silicone release agent for release layer addition reaction type release paper (KS-778, manufactured by Shin-Etsu Chemical Co., Ltd.) 32 parts Catalyst (CAT-PL-8, manufactured by Shin-Etsu Chemical Co., Ltd.) 0.32 parts Toluene 67.68 parts

Finally, as an antistatic treatment on the receiving layer surface,
Quaternary ammonium salt compound (manufactured by Matsumoto Yushi Seiyaku Co., Ltd.
(1/1000 dilution of TB-34) was applied. next,
The resulting thermal transfer image-receiving sheet for sealing was slit. In the slit processing, both sides of the thermal transfer image-receiving sheet for sealing were cut off by 5 mm, and slit into 100 mm width to divide into 9 equal parts. At the time of slitting, the cutter slit the non-adhesive portion formed in the band shape, so that the adhesive did not adhere to the cutter.

Next, half cut was performed from the antistatic treatment surface to the pressure-sensitive adhesive layer (see FIG. 11). As shown in the enlarged view of one screen shown in FIG. 13, a total of 16 stickers were formed on each screen, four in each of the vertical and horizontal directions. The entire outer periphery of each seal was surrounded by a half cut, and three places of the outer periphery were formed as shallow half cuts 51. In order to prevent peeling during printing, the shallow half cut has a total of two places on the front side 37 in the printing direction, one near each end, and a rear side 3 in the printing direction.
In FIG. 8, one portion is provided at substantially the center. Since the front side in the printing direction is fixed by two shallow half cuts near both ends, peeling of the seal can be completely prevented, and the rear side in the printing direction is a shallow half cut in the approximate center, but even if it comes off in the rear, If the front is fixed, the whole seal will not peel off, and it is sufficient. If a half-cut that is shallower than necessary is provided, it will be a problem when peeling off the seal. At the same time as the half-cut processing, a detection hole as a detection mark was opened.

(Comparative Example 1) A roll of the thermal transfer image-receiving sheet for sealing of Example was used except that the pressure-sensitive adhesive reducing agent was not applied.
In the same manner as in Example, a thermal transfer image-receiving sheet for sealing of Comparative Example was prepared.

(Evaluation) Images were formed with a printer using the heat transfer image-receiving sheets for sealing of Examples and Comparative Examples. In the thermal transfer image-receiving sheet for sealing of Example, the adhesive was not exposed on the side surface of the sheet, so that the adhesive did not adhere to the transport mechanism in the printer, no transport failure occurred, and normal printing was possible. However, the heat transfer image-receiving sheet for sealing of the comparative example is such that the adhesive is exposed on the side surface of the sheet, so the pressure-sensitive adhesive adheres to the transport mechanism in the printer, and when about 50 screens are printed, the heat transfer image-receiving sheet for sealing becomes Transport failure occurred. In the thermal transfer image-receiving sheet for sealing of the comparative example, the adhesive adhered to the slitter at the time of production, and the slitter had to be cleaned every about 6000 m slit.

[0052]

According to the present invention, when the sheet is conveyed in the printer, the adhesive comes out from the side of the thermal transfer image-receiving sheet for sealing and does not adhere to the printer conveying mechanism or the cutter. Therefore,
Troubles such as transport failure do not occur. Further, the adhesive does not adhere to the slitter when the slitter processing is performed, and the adhesive does not adhere to the cutter when the cut sheet is manufactured, so that the efficiency of manufacturing the heat transfer image receiving sheet for sealing is also improved.
