Sectional drawing of the hard coat transfer foil 1 by the 3rd modification of FIG.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a cross-sectional view of a hard coat transfer foil 1 according to an embodiment of the present invention, and FIG. A hard coat transfer foil 1 in FIG. 1 includes a PET (polyethylene terephthalate) film 3 as a base material, a melamine release layer 4 disposed on the PET film 3, and a hard coat disposed on the melamine release layer 4. A layer (protective layer) 5, an anchor layer (primer layer) 6 disposed on the hard coat layer 5, and a heat bonding layer (heat seal layer) 7 disposed on the anchor layer 6 are provided.

  Of the layers of the hard coat transfer foil 1 of FIG. 1, the hard coat layer 5, the anchor layer 6, and the thermal bonding layer 7 are the transfer portions 8. The heat bonding layer 7 in the transfer unit 8 is bonded to the surface of the transfer medium 9 in FIG. 2, and the transfer unit 8 is formed on the transfer medium 9. Thereby, the transfer target 2 is completed.

  The hard coat transfer foil 1 in FIG. 1 has a ribbon shape, for example, and is placed on the surface of a transfer medium 9 such as a card and pressed against the transfer medium 9 while heating the PET film 3 with a heat roller. As a result, the transfer portion 8 is transferred to the transfer medium 9. When transfer to one transfer medium 9 is completed, the ribbon is pulled out and transfer to another transfer medium 9 is performed.

  The PET film 3 as a base material is a PET film 3 having a thickness of about 12 μm and subjected to a single-side corona treatment. By the corona treatment, the wettability of the PET film 3 is improved, and the bonding characteristics and the like are improved.

  The material of the two-component curable melamine release layer 4 is disposed on the surface of the corona-treated PET film 3, and heat treatment baking is performed with an infrared dryer to form the melamine release layer 4. The formation of the two-component curable melamine release layer 4 requires baking at about 120 ° C., but if an infrared dryer is used, the thin PET film 3 having a thickness of about 12 μm is not wrinkled by thermal damage. The melamine release layer 4 can be baked.

  If the material of the one-component curable melamine release layer 4 is used, baking must be performed at about 190 ° C., and the PET film 3 may be deformed by heat. It is desirable to use the material of the mold layer 4.

  The thickness of the PET film 3 is set to about 12 μm. When the transfer portion 8 is transferred to the transfer medium 9, it is necessary to apply heat from the PET film 3 side with a heat roller or the like. Heat must be sufficiently transferred to the adhesive layer 7. Considering heat transferability, it is desirable that the thickness of the PET film 3 is thin. However, when the thickness of the PET film 3 is less than 12 μm, when the PET film 3 is formed into a ribbon shape, the PET film 3 is cut with a little force. Therefore, the thickness of the PET film 3 is desirably 12 μm or more, but the upper limit of the thickness is about 16 μm in consideration of heat transferability. That is, the thickness of the PET film 3 is desirably 12 to 16 μm.

  The hard coat layer 5 is desirably a material having a characteristic of easily peeling from the melamine release layer 4 when the transfer portion 8 is transferred to the transfer medium 9. One specific example of the hard coat layer 5 is one in which a hard resin filler that does not dissolve in a solvent is contained in a varnish of a radiation cross-linked cured resin. The hard resin filler in the hard coat layer 5 is preferably a single layer. If the average particle diameter of the hard resin filler is about 80% of the film thickness of the hard coat layer 5, the hard resin filler can be a single layer. When the hard resin filler is not a single layer but a multilayer, the stress applied to the hard coat layer 5 is not uniform, and the foil breakage becomes worse. The average particle size means a volume average particle size, and is measured by a known method using a particle size distribution / particle size distribution measuring device (for example, Nanotrack particle size distribution measuring device, manufactured by Nikkiso Co., Ltd.). Can do.

  Further, the weight blending ratio of the hard resin filler in the radiation cross-linked cured resin of the hard coat layer 5 is desirably 3 to 5%. If the weight blending ratio of the hard resin filler exceeds 5%, the smoothness of the surface of the hard coat layer 5 is deteriorated, and there is a possibility that irregularities are formed on the surface. Further, the hard coat layer 5 may become whitish.

  The thickness of the hard coat layer 5 is 6 ± 1 μm, and the average particle diameter of the hard resin filler is 5 ± 1 μm. The material of the hard resin filler is, for example, hard high molecular weight polyethylene particles or fluorine particles. The weight ratio is, for example, fluorine particles 3 with respect to polyethylene particles 1. It is not desirable to use microsilica as the hard resin filler. Microsilica has poor retention and does not disperse uniformly in the radiation cross-linked cured resin, and also tends to be unable to re-disperse even if stirred because it settles and aggregates during storage before coating. Because.

  Since the radiation cross-linked cured resin used as the varnish of the hard coat layer 5 has a cross-linked structure, the foil breakage is inherently not good. However, the inclusion of a hard resin filler improves the foil breakage. However, as described above, the hard resin filler has a plurality of layers, the weight blending ratio of the hard resin filler exceeds 5%, or the average particle diameter of the hard resin filler is 80% of the film thickness of the hard coat layer 5. It is not good to exceed.

  The radiation cross-linked curable resin does not contain a polyfunctional monomer such as a highly cross-linkable hexafunctional. Since the polyfunctional monomer has a high crosslinking density, cracks are likely to occur when the transfer target 2 is bent or bent. In addition, since the polyfunctional monomer has a large cure shrinkage, the thin PET film 3 having a thickness of about 12 μm shrinks after radiation crosslinking and generates wrinkles. Therefore, as the radiation cross-linked curable resin according to the present embodiment, for example, a radiation curable oligomer UV resin Iupimer is suitable, as will be described in the examples described later.

  In the present embodiment, it is mainly the hard resin filler that keeps the hardness of the hard coat layer 5, and the radiation cross-linked cured resin contributes to ensuring the solvent resistance.

  The anchor layer 6 is provided to bring the hard coat layer 5 and the heat bonding layer 7 into close contact with each other. For the anchor layer 6, for example, a two-component cross-linked cured resin is used. A specific example of the two-component crosslinked cured resin is an isocyanate cured resin.

  The thermal adhesive layer 7 is a layer that is thermally transferred and bonded to the transfer medium 9. The anchor layer 6 and the thermal bonding layer 7 may be integrated into one layer.

  The thickness of each layer of the hard coat transfer foil 1 in FIG. 1 is, for example, 12 μm for the PET film 3, 1 μm for the melamine release layer 4, 6 μm for the hard coat layer 5, 0.4 μm for the anchor layer 6, and the thermal adhesive layer 7. Is 2 μm, but this is only an example.

  FIG. 3 is a cross-sectional view of the hard coat transfer foil 1 according to the first modification of FIG. The hard coat transfer foil 1 in FIG. 3 is obtained by replacing the thermal adhesive layer 7 in FIG. 1 with a receiving and thermal adhesive layer 7a, and the other layer configuration is the same as in FIG.

  The receiving and thermal adhesive layer 7a in FIG. 3 receives the coloring of the sublimation transfer type or melt transfer type ink ribbon. This image receiving surface is directly bonded to the surface of the transfer medium 9 by heat. Further, if necessary, the black timing mark 10 is printed on the surface of the receiving and adhesive layer. As a result, various images can be printed on the surface of the receiving and heat-bonding layer 7a, and the printed image can be transferred to the surface of the transfer medium 9 as it is.

  The thickness of each layer of the hard coat transfer foil 1 in FIG. 3 may be the same as that in FIG. 1, for example, or the thickness of at least some of the layers may be different from that in FIG.

  FIG. 4 is a sectional view of the hard coat transfer foil 1 according to the second modification of FIG. The hard coat transfer foil 1 in FIG. 4 is obtained by replacing the hard coat layer 5 in FIG. 1 with an optical holo diffraction grating embossed hard coat layer 5a and a transparent vapor deposition reflective layer 11, and the other layer configuration is the same as FIG. is there.

  The optical holo diffraction grating embossed hard coat layer 5a is formed, for example, by forming a concavo-convex portion on the surface of the hard coat layer 5 of FIG. 1 by microembossing. Become.

The transparent vapor deposition reflective layer 11 is a material having a refractive index different from that of the hard coat layer 5a, and a transparent metal compound such as zinc sulfide (ZnS) or titanium oxide (TiO ₂ ) is formed on the concavo-convex portion of the hard coat layer 5a. It is formed by vapor deposition. The thickness of the transparent vapor deposition reflective layer 11 is about 50 nm ± 20 nm. The refractive index of the hard coat layer 5 is about 1.4 to 1.5, whereas the refractive index of the transparent vapor deposition reflective layer 11 is about 1.8 to 2.3. Thus, by providing a refractive index difference between the hard coat layer 5a and the transparent vapor deposition reflective layer 11, interference fringes are generated by the hologram diffraction grating formed on the surface of the hard coat layer 5a, and the hologram image is visualized. Is done. In addition, black timing marks 10 are printed on a part of the surface of the transparent vapor deposition reflective layer 11 as necessary.

  The thickness of each layer of the hard coat transfer foil 1 of FIG. 4 may be the same as the thickness of each layer of FIG. 1 except for the transparent vapor deposition reflective layer 11, and the thickness of at least a part of the layers is different from that of FIG. You may do it.

  FIG. 5 is a cross-sectional view of a hard coat transfer foil 1 according to a third modification of FIG. The hard coat transfer foil 1 in FIG. 5 is obtained by replacing the thermal adhesive layer 7 in FIG. 4 with a receiving and thermal adhesive layer 7a, and the other layer configuration is the same as in FIG.

  5 receives the coloring of the sublimation transfer type or melt transfer type ink ribbon in the same manner as the reception / thermal adhesive layer 7a of FIG.

  The thickness of each layer of the hard coat transfer foil 1 in FIG. 5 may be the same as that in FIG. 4, or the thickness of at least a part of the layers may be different from that in FIG.

  The hard coat transfer foil 1 according to the present embodiment shown in FIGS. 1 to 5 described above has the following excellent features 1) to 6).

1) Scratch resistance, abrasion resistance, and scratch resistance The hard resin filler contained in the hard coat layer 5 improves the scratch resistance, wear resistance, and scratch resistance. By using, for example, polymer polyethylene particles or fluorine particles instead of microsilica as the hard resin filler, the hard resin filler can be uniformly dispersed in the radiation cross-linked cured resin, and the overall abrasion resistance of the hard coat layer 5 is improved. Abrasion resistance and scratch resistance are improved.

2) Foil cutting property Since the hard coat layer 5 is a radiation curable resin and does not contain a polyfunctional monomer such as hexafunctional, the foil cutting property is improved. In addition, since the hard coat layer 5 having a thickness of 6 ± 1 μm contains a hard resin filler having a weight blending ratio of about 3 to 5% and an average particle diameter of 5 ± 1 μm, the hard resin filler should have a single layer structure. The foil breakage is improved. Thereby, even when the hard coat transfer foil 1 is formed in a ribbon shape, the hard coat layer 5 can be accurately cut according to the size of the transfer medium 9, and the hard coat layer 5 is formed outside the transfer medium 9. There is no risk of protruding.

3) Transparency Since the hard resin filler contained in the hard coat layer 5 has a weight blending ratio of about 3 to 5%, sufficient transparency can be ensured. If the weight blending ratio of the hard resin filler exceeds 5%, the hard coat layer 5 becomes whitish and the transparency is lowered.

4) Surface smoothness The thickness of the hard coat layer 5 is 6 ± 1 μm, the average particle diameter of the hard resin filler is about 5 ± 1 μm, and the difference between them is only about 20%. The risk of unevenness is reduced. For example, if the average particle diameter of the hard resin filler exceeds 80%, the surface of the hard coat layer 5 will be uneven. On the other hand, if the average particle size of the hard resin filler is about 4 ± 1 μm, the surface of the hard coat layer 5 is partially depressed and irregularities are formed.

  Further, by setting the weight blending ratio of the hard resin filler to about 3 to 5%, the hard resin filler is entirely dispersed in the hard coat layer 5 to improve the uniformity of the film, and the surface of the hard coat layer 5 Improve smoothness.

5) Solvent resistance Since the hard coat layer 5 is a varnish made of a radiation curable resin and contains a hard resin filler, by covering the surface of the transfer medium 9 with such a hard coat layer 5, It is possible to prevent the outermost surface of the transfer medium 9 from being dissolved by the solvent and prevent the image printed on the surface of the transfer medium 9 from being eroded by the solvent.

  Further, when the transfer medium 9 is a card such as plastic, for example, if the transfer unit 8 according to the present embodiment is transferred to both sides of the card, both sides of the card are protected by the hard coat layer 5, and the card is a The image printed on the card surface can be protected even when immersed in the card.

6) Resistance to bending impact and cracking resistance Since the radiation curable resin which is the material of the hard coat layer 5 does not contain a polyfunctional monomer, the transfer medium 9 covered with the hard coat layer 5 is bent or bent. However, the risk of cracks occurring in the hard coat layer 5 is reduced, and the appearance is not impaired.
