Description

  The present invention relates to a transfer printing sheet, and more particularly to a pressure-sensitive transfer type transfer printing sheet.

  As a transfer printing sheet, a pressure-sensitive transfer type transfer printing sheet 91 having a configuration shown in FIGS. 9A and 9B is known (for example, see Patent Document 1). This transfer printing sheet 91 is provided with a printing layer (adhesive printing layer) B having a predetermined pattern made of an adhesive material on a release sheet A having releasability, and then substantially the same as the adhesive printing layer B on the adhesive printing layer B. In particular, a printing layer (ink printing layer) C made of the same pattern of ink is provided, and further, a peelable protective sheet D covering an area larger than the pattern from above the ink printing layer C is provided.

  The transfer operation of the transfer printing sheet having such a structure is as follows. (1) First, the release sheet A is gently peeled off, and (2) the adhesive print layer B is attached to a subject (not shown) and crimped. (3) Next, it is only necessary to peel off the protective sheet D. Therefore, the same pattern that is directly printed on the subject can be transferred and printed with one touch.

  However, the conventional transfer printing sheet 91 has the following problems. That is, the size (planar dimension) of the protective sheet D used for the transfer printing sheet 91 is substantially the same as that of the release sheet A, and the back surface (the surface facing the ink printing layer C) has an adhesive on the entire surface. Usually it is coated.

  Such a transfer printing sheet 91 is shipped with the protective sheet D and the release sheet A adhered to each other as shown in FIG. 9B. For this reason, when the user performs the transfer operation of the transfer printing sheet 91, first, (1) the release sheet A is peeled off, but the release sheet A and the protective sheet D are difficult to peel off, and the work takes time. .

  Next, (2) the adhesive print layer B is stuck to the subject and is crimped. At this time, since the adhesive on the back surface of the protective sheet D is exposed, the positioning of the adhesive print layer B with respect to the subject is in progress. As a result, the back surface of the protective sheet D sticks to the subject, making it difficult to perform a smooth positioning operation.

  Next, (3) the protective sheet D is peeled off. However, if the portion other than the adhesive printing layer B is accidentally pressed in the operation (2), it takes time to remove the protective sheet D from the subject. .

That is, the conventional transfer printing sheet 91 has a problem that it requires skill in the transfer operation and takes a long time for the transfer operation.
Japanese Patent Laid-Open No. 61-132399

  This invention solves the problems of such a conventional transfer printing sheet, can transfer and print a pattern similar to that directly printed on a subject with one touch, and does not require skill in the transfer operation, It is an object of the present invention to provide a transfer printing sheet that can perform a transfer operation smoothly.

  The transfer printing sheet according to the present invention is a transfer in which a printing layer formed by printing is sandwiched between a release-holding surface of a release sheet having release properties and an adhesive-holding surface of a protective sheet having adhesiveness. A printing sheet, wherein the printing layer is substantially the same as the predetermined pattern on the adhesive printing layer, and the adhesive printing layer having a predetermined pattern formed by an adhesive formed on the release-holding surface of the release sheet. A transfer pattern printing region provided with a first ink printing layer formed with ink in a pattern, and a second formed with ink on the releasable holding surface of the release sheet so as to surround the transfer pattern printing region. A non-transfer pattern printing region provided with an ink printing layer.

  The features of the present invention can be broadly shown as described above, but the configuration and contents thereof, together with the objects and features, will be further clarified by the following disclosure in view of the drawings.

  In the transfer printing sheet according to the first invention of the present application, a printed layer formed by printing is sandwiched between a release-holding surface of a release sheet having release properties and an adhesive-holding surface of a protective sheet having adhesiveness. This is a transfer printing sheet. The printing layer includes a transfer pattern printing area and a non-transfer pattern printing area. The transfer pattern printing area includes an adhesive printing layer having a predetermined pattern formed by an adhesive formed on the release-holding surface of the release sheet, and a pattern (transfer pattern) substantially the same as the predetermined pattern on the adhesive printing layer. And a first ink printing layer formed of ink. The non-transfer pattern print area includes a second ink print layer formed of ink on the releasable surface of the release sheet so as to surround the transfer pattern print area.

  Therefore, in the non-transfer pattern printing region, the second ink printing layer adheres to the adhesive holding surface side of the protective sheet, and the adhesive strength of the protective sheet is almost lost. For this reason, it is easier for the user to peel off the release sheet as compared to the conventional transfer printing sheet in which the adhesive holding surface of the protective sheet and the release property holding surface of the release sheet are directly in an adhesive state.

  In addition, as described above, the adhesive force of the protective sheet in the non-transfer pattern printing area is almost lost, so when positioning the transfer pattern with respect to the subject, the protective sheet sticks to the subject and performs a smooth positioning operation. There is no problem that it is difficult to perform.

  In addition, since the adhesive strength of the protective sheet in the non-transfer pattern printing area is almost lost, the transfer pattern part is mistaken when the transfer pattern printing area (transfer pattern part) is attached to the subject and bonded. Even when other portions (non-transfer pattern portions) are also pressed, the subject and the protective sheet do not stick.

  That is, it is possible to realize a transfer printing sheet that can transfer and print the same pattern as that directly printed on a subject with one touch, and can perform transfer operation smoothly without requiring skill in transfer operation. it can.

  The transfer printing sheet according to the second invention of the present application is further between the release property holding surface of the release sheet and the adhesive holding surface of the protective sheet, and between the transfer pattern printing region and the non-transfer pattern printing region, A print separation area where no printing is performed is provided.

  Therefore, it is possible to prevent the adhesive print layer or the first ink print layer constituting the transfer pattern print region and the second ink print layer constituting the non-transfer pattern print region from coming into contact with each other and becoming a combined state. Can do. Therefore, when transferring the transfer pattern part to the subject, it is possible to prevent the transfer pattern part and part of the non-transfer pattern part from being transferred, or conversely, transfer with a part of the transfer pattern part missing. can do.

  The transfer printing sheet according to the third invention of the present application further does not print anything between the release property holding surface of the release sheet and the adhesive holding surface of the protective sheet and in the vicinity of the outer periphery of the transfer printing sheet. An adhesive region for preventing sheet peeling is provided.

  Accordingly, in the adhesive region for preventing sheet peeling, the release-holding surface of the release sheet and the adhesive-holding surface of the protective sheet are in direct contact with each other. Therefore, when cutting the larger transfer printing sheet to obtain the transfer printing sheet, by leaving the release sheet and the protective sheet in an adhesive state in the vicinity of the outer periphery of the transfer printing sheet corresponding to the cutting portion, The release sheet and the protective sheet can be cut integrally. Thereby, the shift | offset | difference of the peeling sheet and protective sheet, etc. by cutting can be prevented, and a beautiful cutting part is obtained.

  In addition, by keeping the release sheet and the protective sheet in the vicinity of the outer periphery of the transfer printing sheet, it is possible to prevent the release sheet from being inadvertently peeled off before the transfer operation such as during the transfer of the transfer printing sheet. be able to.

  The transfer printing sheet according to the fourth invention of the present application is further characterized in that a positioning mark serving as a standard for positioning a predetermined pattern with respect to the subject is provided in the non-transfer pattern printing region.

  Therefore, when positioning a predetermined pattern (transfer pattern) with respect to the subject, the positioning mark can be used as a guide. For this reason, in combination with the fact that the protective sheet does not stick to the subject, for example, positioning can be easily performed by using the positioning mark as a guide while bringing the subject and the protective sheet into contact.

  In the transfer printing sheet according to the fifth invention of the present application, the positioning mark is formed by further printing with ink in the non-transfer pattern printing region, and nothing is printed in the vicinity of the positioning mark. Further, there is provided a temporary tacking adhesive region that is not provided.

  Therefore, the adhesive force of the adhesive holding surface of the protective sheet is not lost in the temporary fixing adhesive region. For this reason, for example, the transfer pattern is positioned with respect to the subject using the positioning mark as a guide, and when the position is determined, the protective sheet is temporarily fixed against the subject by pressing the protective sheet toward the subject in the temporary fixing adhesive area. can do. By temporarily fixing in this way, the transfer pattern can be positioned more accurately.

  The transfer printing sheet according to the sixth invention of the present application is further characterized in that the positioning mark is formed by performing no printing in the non-transfer pattern printing region.

  Therefore, the adhesive strength of the adhesive holding surface of the protective sheet is not lost in the portion with the positioning mark. For this reason, for example, the transfer pattern is positioned with respect to the subject using the positioning mark as a guide, and when the position is determined, the protective sheet is pressed against the subject at the portion where the positioning mark is located, so that the protective sheet is temporarily fixed to the subject. can do. By temporarily fixing in this way, the transfer pattern can be positioned more accurately.

  FIG. 1A is a drawing schematically showing a planar configuration of a transfer printing sheet 1 according to an embodiment of the present invention. FIG. 1B is a drawing schematically showing a cross section IB-IB of the transfer printing sheet 1.

  As shown in FIG. 1B, the transfer printing sheet 1 has a printing layer between a release property retaining surface 3a of the release sheet 3 having releasability and an adhesive property retaining surface 5a of the protective sheet 5 having adhesive properties. 17 is provided.

  The dimensions and material of the release sheet (also referred to as “base material”) 3 are not particularly limited, and for example, a polyester resin film or a polypropylene resin film having a thickness of about 125 μm can be used. The means for imparting releasability to the surface of the release sheet 3 is not particularly limited. For example, it can be formed by applying a silicon thin film (for example, about 1 μm thick) to the surface of the release sheet 3. .

  The dimensions and materials of the protective sheet (also called “application film”) 5 are not particularly limited. For example, a vinyl chloride resin film having a thickness of about 50 to 180 μm, a polyethylene terephthalate resin film, a polyester resin film, and a polypropylene resin. A film or the like can be used.

  Although the color of the protective sheet 5 is not particularly limited, the positional relationship between a transfer pattern printing area 21 and a subject 31 (see FIG. 2B) described later can be seen through the protective sheet 5 during a transfer operation. Further, it is preferably colorless and transparent or translucent, colored and transparent or translucent, and more preferably colorless and transparent or colored and transparent.

  The means for imparting adhesiveness to the surface of the protective sheet 5 is not particularly limited. For example, it is formed by applying an acrylic pressure-sensitive adhesive (for example, about 10 μm thick) to the surface of the protective sheet 5. Can do.

  The print layer 17 is a layer formed by printing, and includes a transfer pattern print region 21 and a non-transfer pattern print region 23.

  The transfer pattern printing region 21 includes an adhesive printing layer 7 and a first ink printing layer 11 formed so as to be stacked in this order on the release property holding surface 3 a of the release sheet 3.

  The adhesive printing layer 7 is obtained by printing an adhesive material on the release sheet 3a of the release sheet 3 in a predetermined pattern. Although the dimension and material of the adhesive printing layer 7 are not particularly limited, for example, the adhesive printing layer 7 can be composed of an acrylic pressure-sensitive adhesive having a thickness of about 10 to 20 μm.

  The first ink print layer 11 is formed on the adhesive print layer 7 by printing ink in a pattern substantially the same as the print pattern of the adhesive print layer 7. The size and material of the first ink printing layer 11 are not particularly limited. For example, the first ink printing layer 11 is obtained by printing an acrylic ink having a thickness of about 10 μm over one layer (single color printing) or multiple layers (multicolor printing). It is done.

  The non-transfer pattern printing area 23 includes a second ink printing layer 15. The second ink printing layer 15 is formed by printing ink on the releasability retaining surface 3 a of the release sheet 3 so as to surround the transfer pattern printing region 21. That is, the second ink print layer 15 is substantially the entire area excluding the transfer pattern print area 21 of the releasability retaining surface 3a of the release sheet 3 (in this embodiment, strictly speaking, the transfer pattern print area 21 and the later-described surface). In the area excluding the print separation area 25). Although the order of the formation process of the 2nd ink printing layer 15 is not specifically limited, Since it can suppress an increase in a man-hour when it performs simultaneously with the formation process of the 1st ink printing layer 11, it is preferable.

  The material of the second ink printing layer 15 is not particularly limited. For example, the second ink printing layer 15 can be obtained by printing acrylic ink over one layer (single color printing) or multiple layers (multicolor printing). The thickness of the ink per color of the second ink printing layer 15 is not particularly limited, but is preferably about 3 to 20 μm, more preferably about 5 to 15 μm.

  The color of the ink of the second ink print layer 15 is not particularly limited, and for example, a colorless transparent or translucent one, a colored transparent or translucent one, an opaque one, etc. can be used. However, during the transfer operation, the second ink is used so that the positional relationship between the transfer pattern print region 21 and the subject 31 (see FIG. 2B) can be seen through the second ink print layer 15 attached to the protective sheet 5. The color of the ink of the printing layer 15 is preferably colorless and transparent or translucent, colored and transparent or translucent, and more preferably colorless and transparent or colored and transparent.

  The transfer print sheet 1 further includes a print separation area 25 (of course, the transfer print sheet 1 can be configured not to provide the print separation area 25). The print separation region 25 is between the release property holding surface 3 a of the release sheet 3 and the adhesive holding surface 5 a of the protective sheet 5, and between the transfer pattern printing region 21 and the non-transfer pattern printing region 23. Provided, nothing is printed in this area.

  That is, in the print separation area 25, the adhesive print layer 7 constituting the transfer pattern print area 21, the first ink print layer 11, and the second ink print layer 15 constituting the non-transfer pattern print area 23. No other printing layers are formed, and the releasability retaining surface 3a of the release sheet 3 and the adhesive retaining surface 5a of the protective sheet 5 are in contact directly or via a space.

  By providing the print separation area 25, either the adhesive print layer 7 constituting the transfer pattern print area 21 or the first ink print layer 11 and the second ink print layer constituting the non-transfer pattern print area 23 are provided. 15 can be prevented from contacting and joining.

  As a result, when the transfer pattern print area 21 (transfer pattern portion) is transferred to the subject 31 (see FIG. 2B), a part of the non-transfer pattern print area 23 (non-transfer pattern portion) is transferred to the subject 31 together with the transfer pattern portion. It is possible to prevent transfer or, conversely, transfer to the subject 31 with a part of the transfer pattern portion missing.

  The width of the print separation region 25 is not particularly limited, but is preferably 0.2 mm to 10 mm, more preferably 0.3 mm to 5 mm, and still more preferably 0.5 mm to 3 mm. If the width of the print separation area 25 is too narrow, high printing accuracy is required, resulting in a decrease in yield and cost. On the other hand, if the width of the print separation area 25 is too wide, the transfer pattern portion is positioned with respect to the subject 31. This is because it becomes difficult for the protective sheet 5 to adhere to the subject 31 and perform a smooth positioning operation.

  The upper limit of the width of the print separation area 25 is the maximum non-transfer portion distance S in the transfer print sheet 1 (the maximum value of the distance from each side of the transfer print sheet 1 to the outer periphery of the transfer pattern print area 21: see FIG. 1A. ) Can also be used to express: That is, the width of the print separation region 25 is not particularly limited, but is preferably 0.2% to 50 percent of the non-transfer portion maximum distance S, more preferably 0.3 mm to 25 of the non-transfer portion maximum distance S. Percentage, more preferably 0.5 mm to 10 percent of the non-transfer portion maximum distance S.

  Thus, in the formed transfer printing sheet 1, in order to make transfer operation easy, it is preferable to set the adhesion strength between each member as follows.

That is, the adhesion strength between the adhesive printed layer 7 and the release property retaining surface 3a of the release sheet 3 is F (7-3), and the adhesion strength 5a of the protective sheet 5 and the first ink printed layer 11 are adhered. The strength is F (5-11), the adhesive strength between the adhesive print layer 7 and the surface of the subject 31 is F (7-31), the adhesive print layer 7 constituting the transfer pattern print region 21, and the first ink print layer 11 is F (21), the adhesion strength between the second ink printing layer 15 and the release sheet retaining surface 3a of the release sheet 3 is F (15-3), and the adhesive retaining surface 5a of the protective sheet 5 is. And the second ink print layer 15 is F (5-15), and the adhesion strength between the second ink print layer 15 and the surface of the subject 31 is F (15-31), the following inequality is It is preferable to set so that all are satisfied.
F (7-31)> F (5-11)> F (7-3)
F (21)> F (5-11)
F (5-15)> F (15-3)
F (5-15)> F (15-31)

  Next, the transfer operation of the transfer printing sheet 1 will be described with reference to FIGS. 1A to 3B. 2A, 2B, and 3B are schematic cross-sectional views for explaining the transfer operation of the transfer printing sheet 1, and FIG. 3A is a schematic plan view corresponding to FIG. 3B.

  (1) First, the release sheet 3 is peeled off from the state shown in FIG. 1B. At this time, as described above, the relationship between the adhesion strengths is F (5-11)> F (7-3) and F (21)> F (5-11), so that the transfer pattern printing region 21 is configured. The adhesive printing layer 7 and the first ink printing layer 11 remain attached to the adhesive holding surface 5a of the protective sheet 5 as a whole. Further, since F (5-15)> F (15-3), the second ink printing layer 15 remains attached to the adhesive holding surface 5a of the protective sheet 5.

  Similarly to the adhesion strength F (7-3), the adhesion strength F (15-3) may be set to a minimum adhesion strength at which the release sheet 3 does not peel off naturally. Easy.

  After peeling off the release sheet 3, the transfer printing sheet 1 is in the state shown in FIG. 2A. In this state, the second ink printing layer 15 is attached to the adhesive holding surface 5a of the protective sheet 5 existing in the non-transfer pattern printing region 23, and the adhesiveness of the protective sheet 5 is lost.

  (2) Next, positioning of the transfer pattern printing area 21 with respect to the subject 31 is performed, and when the position is determined, the transfer pattern printing area 21 is pressed toward the subject 31 from above the protective sheet 5, thereby transferring the transfer pattern printing area. The adhesive print layer 21 is pressed onto the subject 31. This state is shown in FIG. 2B.

  When positioning the transfer pattern printing region 21 with respect to the subject 31, if the ink of the second ink print layer 15 and the protective sheet 5 are made transparent (or translucent), the second ink print layer 15 and the protective sheet 5 are set. This is convenient because the subject 31 can be seen through. At this time, as described above, since the adhesiveness of the protective sheet 5 existing in the non-transfer pattern printing region 23 is lost, it is difficult for the protective sheet 5 to adhere to the subject 31 and perform a smooth positioning operation. There is no problem of becoming.

  (3) Next, the protective sheet 5 is peeled off from the state of FIG. 2B. At this time, as described above, the relationship between the adhesion strengths is F (7-31)> F (5-11) and F (21)> F (5-11), so that the transfer pattern printing region 21 is configured. The adhesive print layer 7 and the first ink print layer 11 remain attached to the surface of the subject 31 as a whole. Further, since F (5-15)> F (15-31), the second ink print layer 15 does not adhere to the surface of the subject 31, but remains attached to the adhesive holding surface 5a of the protective sheet 5. It is removed together with the protective sheet 5.

  As described above, since the adhesiveness of the protective sheet 5 existing in the non-transfer pattern printing region 23 is lost, the non-transfer pattern is erroneously pressed when the transfer pattern print region 21 is pressed toward the subject 31. Even if the printing area 23 is also pressed, the subject 31 and the protective sheet 5 do not stick. For this reason, the peeling operation | work of the protection sheet 5 is easy.

  The state where the protective sheet 5 is removed is shown in FIGS. 3A and 3B. In this way, only the adhesive print layer 7 and the first ink print layer 11 constituting the transfer pattern print region 21 can be collectively transferred to the surface of the subject 31.

  In the transfer printing sheet 1, the transfer pattern printing area 21 provided with only the adhesive printing layer 7 and the first ink printing layer 11 is illustrated as the transfer pattern printing area. It is not limited to this. For example, a layer other than the adhesive printing layer and the first ink printing layer may be further provided on and / or below the first ink printing layer 11.

  Next, FIG. 4A schematically shows a planar configuration of a transfer printing sheet 41 according to another embodiment of the present invention. FIG. 4B is a drawing schematically showing a cross section IVB-IVB of the transfer printing sheet 41.

  The basic configuration of the transfer printing sheet 41 and the possibility of variations are the same as those of the transfer printing sheet 1 described above. However, the transfer printing sheet 41 is different from the transfer printing sheet 1 in that it further includes an adhesive region 43 for preventing sheet peeling.

  The adhesive region 43 for preventing sheet peeling is between the releasable holding surface 3a of the release sheet 3 and the adhesive holding surface 5a of the protective sheet 5, and in the vicinity of the outer periphery of the transfer printing sheet 41 (in this embodiment, In the vicinity of a pair of left and right outer peripheries 45 on the drawing), nothing is printed in this area 43.

  That is, in the adhesive region 43 for preventing sheet peeling, the layers 7 and 11 constituting the transfer pattern printing region 21, the second ink printing layer 15 constituting the non-transfer pattern printing region 23, and other printing layers are provided. None of them are formed, and the release-holding surface 3a of the release sheet 3 and the adhesive-holding surface 5a of the protective sheet 5 are in direct contact with each other, and both are in an adhesive state.

  For this reason, for example, when a larger transfer print sheet is cut to obtain the transfer print sheet 41, the release sheet 3 and the protective sheet 5 are adhered to each other in the vicinity of the outer periphery 45 of the transfer print sheet 41 corresponding to the cut portion. By doing so, the release sheet 3 and the protective sheet 5 can be integrally cut. Thereby, the shift | offset | difference etc. of the peeling sheet 3 and the protection sheet 5 by cutting can be prevented, and the beautiful cutting part is obtained.

  Further, by leaving the release sheet 3 and the protective sheet 5 in an adhesive state in the vicinity of the outer periphery of the transfer print sheet 41, the release sheet 3 is inadvertently peeled off before the transfer operation such as during the transfer of the transfer print sheet 41. Can be prevented.

  Although the width | variety of the adhesion area | region 43 for sheet | seat peeling prevention is not specifically limited, Preferably it is 0.2 mm-20 mm, More preferably, it is 1 mm-15 mm, More preferably, it is 2 mm-10 mm. If the width of the adhesive region 43 for preventing sheet peeling is too narrow, the peeling preventing function of the peeling sheet 3 is impaired. On the other hand, if the width is too wide, the protective sheet 5 is positioned when the transfer pattern portion is positioned with respect to the subject 31. This is because it becomes difficult to perform a smooth positioning operation by sticking to each other.

  In addition, the upper limit of the width | variety of the adhesion area | region 43 for sheet | seat peeling prevention can also be expressed as follows using the non-transfer part maximum distance S (refer FIG. 1A) in the transfer printing sheet 1. FIG. That is, the width of the sheet peeling prevention adhesive region 43 is not particularly limited, but preferably 0.2 mm to 50 percent of the non-transfer portion maximum distance S, more preferably 1 mm to 35 of the non-transfer portion maximum distance S. Percentage, more preferably 2 mm to 25 percent of the maximum non-transfer portion distance S.

  In the transfer printing sheet 41, a portion having the second ink printing layer 15 in the non-transfer pattern printing area 23 is placed between the outer periphery (outer periphery 45) of the transfer printing sheet 41 and the sheet peeling prevention adhesive area 43. Has been. This portion of the non-transfer pattern printing area 23 is referred to as a peeling printing area 47. In the release printing region 47, the release sheet 3 and the protective sheet 5 are not in an adhesive state. Therefore, the release sheet 3 can be easily peeled by providing the peeling print area 47.

  Although the dimension of the peeling printing area 47 is not particularly limited, it is preferably about 0.2 mm to 10 mm, more preferably about 0.5 mm to 5 mm. This is because if the size of the release printing area 47 is too small, a finger or the like is not applied when the release sheet 3 is peeled off, and conversely if it is too large, the deviation between the release sheet 3 and the protective sheet 5 due to cutting cannot be prevented.

  In the transfer printing sheet 41, the peeling printing region 47 is provided over the entire outer periphery 45 (full length) of the transfer printing sheet 41, but this is not always necessary. For example, it may be provided only at some corners of the outer periphery of the transfer printing sheet 41 or may be provided only near the center of some sides.

  Of course, it is also possible not to provide the peeling printing area 47 at all. In this case, an adhesive region 43 for preventing sheet peeling is provided continuously on the outer periphery (outer periphery 45) of the transfer printing sheet 41. If comprised in this way, the shift | offset | difference etc. of the peeling sheet 3 and the protection sheet 5 by cutting can be prevented more reliably.

  In the transfer printing sheet 41, the sheet peeling prevention adhesive region 43 is provided in a band shape in the vicinity of the pair of left and right outer peripheries 45 on the drawing. It is not limited. For example, the sheet peeling preventing adhesive region 43 may be provided only in the vicinity of one of the pair of left and right outer peripheries 45 on the drawing. Further, it may be provided in the vicinity of one or more outer peripheries of the pair of left and right outer peripheries 45 and the pair of upper and lower outer peripheries 49 in the drawing, or in the vicinity of all the outer peripheries.

  Further, the shape and arrangement pattern of the adhesive region for preventing sheet peeling are not particularly limited. FIG. 5A is a drawing schematically showing a planar configuration of a transfer printing sheet 51 according to still another embodiment of the present invention. FIG. 5B is a drawing schematically showing a cross section VB-VB of the transfer printing sheet 51.

  That is, in the transfer printing sheet 51, the adhesive region for preventing sheet peeling is not the continuous strip-like sheet peeling preventing adhesive region 43 in the transfer printing sheet 41 but a discontinuous dot-like (square in the example of FIG. 5A). An adhesive region 53 for preventing sheet peeling is provided. Other configurations and possible variations are the same as those of the transfer printing sheet 41. Of course, the shape of the adhesive region 53 for preventing sheet peeling can be other than a square, for example, a circle.

  In the transfer printing sheet 51, the dotted sheet peeling prevention adhesive regions 53 are arranged at the same pitch in the same direction (vertical direction or horizontal direction) in the drawing, but the invention is not limited to this. For example, the adhesive regions 53 for preventing sheet peeling may be provided at an equal pitch over the entire area near the outer periphery of the transfer printing sheet 51, or may be at an unequal pitch.

  In the transfer print sheet 51, the plurality of sheet peeling prevention adhesive regions 53 are provided over the entire area near the outer periphery of the transfer print sheet 51, but of course, only a part of the transfer print sheet 51 near the outer periphery is provided. May be.

  Further, in the transfer printing sheet 51, as in the case of the transfer printing sheet 41, the peeling printing area 57 is provided, but the peeling printing area 57 may be configured not to be provided.

  Next, FIG. 6A schematically shows a planar configuration of a transfer printing sheet 61 according to still another embodiment of the present invention. FIG. 6B is a drawing schematically showing a section VIB-VIB of the transfer printing sheet 61.

  The basic configuration of the transfer printing sheet 61 and the possibility of variations are the same as those of the transfer printing sheet 1 described above. However, the transfer print sheet 61 is different from the transfer print sheet 1 in that it further includes a positioning mark 63 and a temporary fixing adhesive region 65.

  The positioning mark 63 is provided in the non-transfer pattern printing area 23 to serve as a guide for positioning the transfer pattern printing area 21 with respect to the subject 31 during the transfer operation.

  Therefore, in the above positioning, coupled with the fact that the protective sheet 5 does not stick to the subject 31, for example, the positioning mark 63 can be used as a guide while the subject 31 and the protective sheet 5 are in contact with each other, so that the positioning can be easily performed. .

  In the transfer printing sheet 61, the positioning mark 63 is formed by printing with ink in the non-transfer pattern printing region 23.

  The temporary fixing adhesive area 65 is located in the vicinity of the positioning mark 63 in the non-transfer pattern printing area 23 as an area where nothing is printed.

  Therefore, the adhesive force of the adhesive holding surface 5a of the protective sheet 5 is not lost in the temporary fixing adhesive region 65. Therefore, for example, the transfer pattern printing area 21 is positioned with respect to the subject 31 with the positioning mark 63 as a guideline, and when the position is determined, the protective sheet 5 is pressed toward the subject 31 in the temporary fixing adhesive region 65, thereby The protective sheet 5 can be temporarily fixed to 31. By temporarily fixing in this way, the transfer pattern printing region 21 can be positioned more accurately.

  In order to sufficiently exhibit such a function, preferably, the protective sheet 5 is transparent (or translucent), the ink of the second ink print layer 15 is transparent (or translucent), and the positioning mark 63 These inks are colored transparent (or translucent) or opaque. More preferably, the protective sheet 5 is colorless and transparent (or colorless and translucent), the ink of the second ink printing layer 15 is colored and transparent (or colored and translucent), and the ink of the positioning mark 63 is opaque.

  In the transfer printing sheet 61, two sets of the positioning mark 63 and the temporary fixing adhesive region 65 are provided on the left and right symmetrical positions with the transfer pattern printing region 21 in between in the drawing, but the positioning mark 63 and the temporary fixing adhesive region 65 are provided. The number of sets, positions, and arrangement patterns of 65 are not limited to this.

  For example, only one set of the positioning mark 63 and the temporary adhesive layer 65 may be provided. Further, two sets of positioning marks 63 and temporary fixing adhesive regions 65 may be provided in a vertically symmetric position across the transfer pattern printing region 21 in the drawing, or a total of four sets may be provided vertically and horizontally.

  In the transfer printing sheet 61, the positioning mark 63 is linear (rectangular) and the temporary fixing adhesive region 65 is elliptical. However, the positioning mark 63 and the temporary fixing adhesive region 65 are illustrated. However, the shape is not limited to this. For example, the positioning mark 63 may be a cross or a triangle, and the temporary fixing adhesive region 65 may be a circle or a square.

  Further, the positioning mark 63 and the temporary fixing adhesive region 65 do not necessarily need to be used in close proximity as shown in FIG. 6A, and the positioning mark 63 and the temporary fixing adhesive region 65 may be arranged apart from each other. The number of positioning marks 63 may be different from the number of temporary fixing adhesive regions 65. Further, only one of the positioning mark 63 and the temporary fixing adhesive region 65 may be used.

  Moreover, in the transfer printing sheet 61 of FIG. 6A, although the case where the adhesive area | region for sheet | seat peeling prevention is not provided is illustrated, of course, it is not limited to this. For example, the transfer print sheet 61 in FIG. 6A can be used in combination with the above-described adhesive region 43 for preventing sheet peeling in the transfer print sheet 41 or the adhesive region 53 for preventing sheet peel in the transfer print sheet 51.

  Further, when the positioning mark and the temporary adhesive layer are used in pairs, the positional relationship is not particularly limited. FIG. 7A is a drawing schematically showing a planar configuration of a transfer printing sheet 71 according to still another embodiment of the present invention. FIG. 7B is a drawing schematically showing a section VIIB-VIIB of the transfer printing sheet 71.

  That is, the transfer printing sheet 71 is configured such that the positioning mark 73 and the temporary fixing adhesive region 75 are not arranged at different positions as in the transfer printing sheet 61 but are stacked. That is, the positioning mark 73 is formed in a part of the temporary fixing adhesive region 75.

  In this way, the positioning mark 73 and the temporary tacking adhesive area 75 are brought close to the limit (that is, they are arranged so as to overlap each other), thereby pressing the positioning mark 73 and simultaneously pressing the surrounding temporary tacking adhesive area 75. It is possible to perform positioning and temporary fixing more accurately. The remaining configuration and possible variations of the transfer printing sheet 71 are the same as those of the transfer printing sheet 61.

  Next, FIG. 8A schematically shows a planar configuration of a transfer printing sheet 81 according to still another embodiment of the present invention. FIG. 8B is a drawing schematically showing a section VIIIB-VIIIB of the transfer printing sheet 81.

  The basic configuration of the transfer printing sheet 81 and the possibility of variations are the same as those of the transfer printing sheet 71 described above. However, the positioning mark 83 on the transfer printing sheet 81 is different from the positioning mark 73 on the transfer printing sheet 71 in that it is configured as an area where nothing is printed in the non-transfer pattern printing area 23.

  And the adhesion area for temporary fixing is not provided in particular. This is because in the transfer printing sheet 81, the positioning mark 83 functions as both the positioning mark 73 and the temporary fixing adhesive region 75 in the transfer printing sheet 71.

  That is, in the transfer printing sheet 81, the adhesive strength of the adhesive holding surface 5a of the protective sheet 5 is not lost in the portion where the positioning mark 83 is present. For this reason, for example, the transfer pattern printing region 21 is positioned with respect to the subject 31 using the positioning mark 83 as a guideline, and when the position is determined, the protective sheet 5 is pressed toward the subject 31 at the position of the positioning mark 83, thereby In contrast, the protective sheet 5 can be temporarily fixed. By temporarily fixing in this way, the transfer pattern printing region 21 can be positioned more accurately.

  In order to sufficiently exhibit such a function, preferably, the protective sheet 5 is transparent (or translucent), and the ink of the second ink printing layer 15 is colored transparent (or colored translucent) or opaque. . More preferably, the protective sheet 5 is colorless and transparent (or colorless and translucent), and the ink of the second ink printing layer 15 is colored and transparent (or colored and translucent).

  The dimension of the positioning mark 83 is not particularly limited, but is preferably configured to be within a circle of 1 mm to 20 mm, more preferably 2 mm to 10 mm. Since the positioning mark 83 must have the functions of the positioning mark and the temporary fixing adhesive region, if it is too large, the function as the positioning mark is sacrificed, and if it is too small, the function as the temporary fixing adhesive region is impaired. is there.

  In addition, although the kind of printing used for the various printing processes in each of the above embodiments is not particularly limited, for example, among silk printing, offset printing, seal printing, pad printing, gravure printing, laser printing, and inkjet printing Any one or a combination of a plurality of printings can be used.

  Although the present invention has been described above as a preferred embodiment, the terminology has been used for description rather than limitation and departs from the scope and spirit of the present invention. Without departing from the scope of the appended claims. Also, while the above describes only some exemplary embodiments of the present invention in detail, those skilled in the art will recognize the exemplary implementations described above without departing from the novel teachings and advantages of the present invention. It will be readily appreciated that many variations in form are possible. Accordingly, all such modifications are intended to be included within the scope of the present invention.
