Description

  The present invention relates to a seal type thermal transfer image receiving sheet.

  A thermal transfer image is formed on a transfer-substrate using the sublimation transfer method because it is excellent in transparency, has high reproducibility and gradation of intermediate colors, and can easily form high-quality images equivalent to conventional full-color photographic images. It is widely done. Examples of prints on which a thermal transfer image is formed on a transfer object include digital photographs and ID cards used in many fields such as identification cards, driver's licenses, and membership cards.

  For the formation of a thermal transfer image by a sublimation transfer method, a thermal transfer sheet having a dye layer provided on one surface of a base material and a thermal transfer member having a receiving layer provided on one surface of another object, for example, another base material. An image receiving sheet is used. Then, the receiving layer of the thermal transfer image-receiving sheet and the dye layer of the thermal transfer sheet are overlapped, and heat is applied from the back side of the thermal transfer sheet by a thermal head to transfer the dye of the dye layer onto the receiving layer. A print having a thermal transfer image formed thereon is obtained. According to such a sublimation transfer method, since the transfer amount of the dye can be controlled by the amount of energy applied to the thermal transfer sheet, the density gradation can be performed. High quality prints comparable to images can be formed.

  In recent years, a heat transfer image receiving sheet (hereinafter, referred to as a “seal type thermal transfer image receiving apparatus”) is provided on a release sheet portion, in which a seal portion formed by laminating an adhesive layer, a base material layer, and a receiving layer is detachably provided from the release sheet portion. Sheet). In such a seal type thermal transfer image receiving sheet, after forming a desired image on the receiving layer, the sealing portion is peeled off from the release sheet portion, and the receiving layer on which the image has been formed can be applied to any target via an adhesive layer. It can be attached to objects. Such a seal-type thermal transfer image-receiving sheet has a wide range of usage forms as compared with a conventional thermal transfer image-receiving sheet, and its use in the amusement field such as a print sealing machine is attracting attention.

  Many users store a photo sticker made by a print sticker in a holder without peeling off the seal portion. When the holder is placed at home, there is a possibility that the photo sticker may be broken or stained before the photo sticker is produced by a print seal machine at an amusement facility before being taken home. Also, when the photo sticker is stored in the holder, the seal may be bent and wrinkled.

  A printed matter (photo sticker) is manufactured using the seal-type thermal transfer image receiving sheet 1 having the above-described configuration. For example, a thermal transfer printer superposes the seal-type thermal transfer image-receiving sheet 1 and a dye-containing thermal transfer sheet, heats the thermal transfer sheet according to image data, and transfers the heat-transfer sheet to the receiving layer 24 of the seal-type thermal transfer image-receiving sheet 1. The dye is transferred to form an image and a photographic sticker is manufactured.

  For example, as shown in FIGS. 2A and 2B, the photo sticker has an image obtained by photographing a user printed on a seal unit 20 on the front side and a protective seal 30 provided on the back side. FIG. 2A shows an example of a photo sticker manufactured in a two-person mode. This photo sticker includes a photo sticker 1A serving as a storage area for user A, a photo sticker 1B serving as a storage area for user B, and a photo sticker 1C serving as a distribution area. The thermal transfer printer prints the boundaries L1, L2 of the photo stickers 1A, 1B, 1C, and the user may cut the boundaries with the scissors along the boundaries, or cut the photo stickers 1A, 1B, 1C with the cutter in the thermal transfer printer. May be output. A perforation 50 may be pre-processed in the center of the photo sticker 1C, and the photo sticker 1C may be divided into two so that each of the users A and B can own it.

  Each of the photo stickers 1A and 1B has an opening 40 formed at an end thereof in advance. A punch mechanism for forming the opening 40 in the thermal transfer printer may be provided.

  When the user A receives the photo sticker 1A, the user A peels off the protective seal 30 on the back side as shown in FIG. Then, as shown in FIG. 3B, the user A attaches the protective seal 30 so as to cover the seal part 20 on the front side. FIG. 4 is a cross-sectional view of the photographic seal in a state where the protective seal 30 is stuck on the seal section 20.

  The photographic sticker 1A in which the protective seal 30 is stuck on the seal portion 20 is stored in a dedicated holder H as shown in FIG. Alternatively, as shown in FIG. 5 (b), it is stored through the ring R in the opening 40. The diameter of the opening 40 is desirably about φ6 ± 0.5 mm, which is a JIS drilling standard for office drilling machines. By setting the diameter of the opening 40 in this range, the photo seal filed with the ring R can be easily turned over, and a sufficient image forming area can be secured.

  Affixing the protective seal 30 on the seal portion 20 protects the image and prevents dirt and scratches. Also, by attaching the protective seal 30 as compared with the case where the protective seal 30 is not provided, the strength (rigidity) of the photographic seal 1A is increased, and breakage such as bending can be prevented.

  As shown in FIG. 6, a seal part 20 </ b> C transferred from another user may be attached to the surface of the release sheet 10 where the release layer 13 is exposed after the protective seal 30 is peeled off. The protective seal 30 on the back side of the photo seal 1C may be peeled off, and the protective seal 30 may be attached so as to cover the seal portion 20C.

Good. For example, as shown in FIG. 7, the adhesive layer 31 is provided in a rectangular frame shape only on the peripheral edge of the protective seal 30, and the central portion of the seal portion 20 that contacts the image forming area is protected without providing the adhesive layer 31. The structure is such that the layer 32 is exposed. As a result, the convenience of storage can be improved, for example, when the user wants to remove the stored photo sticker.

  The seal type thermal transfer image-receiving sheet 1 may be provided with a cut (half cut) extending from the protective layer 32 to the surface of the release layer 13 in the thickness direction to facilitate peeling of the protective seal 30. As shown in FIG. 6, when the protective seal 30 is attached so as to cover the seal portion 20C provided on the back surface, the half-cut shape of the protective seal of the photographic seal 1A is slightly smaller than the outer dimensions of the photographic seal 1A. Even if the adhesive force between the release sheet and the protective seal is small, the adhesive force between the protective seal and the half-cut outer peripheral portion of the remaining protective seal may be secured, and the protective function of the seal may be improved. The seal type thermal transfer image receiving sheet 1 may be provided with a cut (half cut) extending from the receiving layer 24 to the surface of the release layer 12 in the thickness direction to facilitate peeling of the seal portion 20.

  In the above embodiment, as shown in FIG. 2A, an example of the layout of the photo sticker produced in the two-person mode has been described. However, the number of persons is not limited to two, and may be one, three or more. May be. FIG. 8 shows an example of a layout of a photo sticker manufactured in the three-person mode. From the thermal transfer printer, the photographic stickers 1D, 1E, and 1F for storage and the photographic stickers 1G for distribution of each of the three users are output as one sheet or divided. An opening 40 is provided in each of the photo stickers 1D, 1E, and 1F.

  It is preferable that the storage photo stickers 1D, 1E, and 1F and the distribution photo sticker 1G have a rectangular layout (or a substantially rectangular R-shaped corner) and the same dimensions. By arranging the size and shape of the storage photo stickers 1D, 1E, and 1F, when storing a bundle of a plurality of photo stickers through a ring through the opening 40, the photo stickers can be easily turned over and the photo stickers can be folded. Can be prevented. If photo stickers having different sizes are bundled together, a photo sticker having a large size may be broken or a photo sticker having a small size may be difficult to turn over. By making the dimensions of the photo stickers uniform, such a problem can be prevented.

  If the distribution seal is placed on the back of the storage seal and secured with the protective seal on the back of the distribution seal, if the layout dimensions of the storage seal and the distribution seal are the same, the protective seal will be The size is suitable for pasting on the back side.

  A pattern may be provided on the protective layer 32.

  The thermal transfer printer may transfer the dye to the receiving layer 24 of the seal portion 20 to form an image, and then transfer the protective layer on the receiving layer 24. In this case, the protective seal 30 is stuck on the seal part 20 via the protective layer.

  As shown in FIG. 9, instead of the protective layer 32 of the protective seal 30, a transparent substrate 33 using a stretched or unstretched film of a plastic such as polypropylene may be provided.

  As shown in FIG. 10, a half cut 60 may be provided from the transparent base material 33 to the middle part of the release sheet 10 in the thickness direction, so that the protective seal 30 may be easily peeled. In addition, a half cut 62 that extends from the receiving layer 24 to the middle part of the release sheet 10 in the thickness direction may be provided to facilitate peeling of the seal portion 20. It is preferable that the size of the portion surrounded by the half cut 60 be larger than the size of the portion surrounded by the half cut 62. Thereby, the protection seal 30 peeled off the release sheet 10 along the half cut 60 becomes larger than the seal part 20 peeled off the release sheet 10 along the half cut 62, and the seal part 20 adhered to the object is formed. When the protective seal 30 is attached thereon, the protective seal 30 can cover the entire seal portion 20.

  The protective layer 32 of the protective seal 30 may be colored. In this case, a reversal image is formed on the receiving layer 24, the seal portion 20 is affixed to the object, the protective seal 30 including the colored protective layer is affixed on the seal portion 20, and the receiving layer 24 is attached to the object via the object. The formed image may be viewed.

  As shown in FIG. 11, a receiving layer 34 may be further provided on the transparent substrate 33 (the surface of the transparent substrate 33 opposite to the adhesive layer 31). The receiving layer 34 is for receiving the sublimation dye transferred from the thermal transfer sheet and maintaining the formed image. As a resin for forming the receiving layer 34, the same material as the material of the receiving layer 24 described above can be used.

  A primer layer may be provided between the transparent substrate 33 and the receiving layer 34. This primer layer may contain a white pigment, a pearl pigment, a metal pigment, and the like.

  By providing the receiving layer 34, the receiving layers are arranged on both surfaces of the seal type thermal transfer image receiving sheet 1. An image can be formed on the receiving layer 24 and the receiving layer 34 by using a known double-sided printer.

  After the dye is transferred to the receiving layer 34 of the protective seal 30 to form an image, the protective layer may be transferred onto the receiving layer 34.
