Description

  The present invention relates to a film with a hologram pattern and a method for producing a film with a hologram pattern, and in particular, even if an ink layer is directly formed on the concavo-convex surface of the hologram pattern, the hologram pattern can be visually recognized. The present invention relates to a film with a hologram pattern that can express a hologram pattern and a method for producing a film with a hologram pattern.

  In recent years, for the purpose of improving decoration and security, a device having a hologram pattern on the outer surface of a container, package or other object has been proposed. This hologram pattern is a pattern of interference fringes recorded in a plane, which is formed into a fine uneven shape forming an embossed shape or a relief shape, and is formed directly on the outer surface of an object or separately formed The method of sticking to the outer surface of a container is examined.

  As a method for directly forming the hologram pattern on the outer surface of the container, a method has been proposed in which a metal plate on which a concavo-convex hologram pattern is formed is pressed against the surface of the container, which is an object, and released. In addition, as a method of separately forming the hologram pattern, after the concave and convex hologram pattern formed on the matrix made of a metal thin film is pressure-molded into a thermoplastic resin or an ultraviolet curable resin, and the resin is cured, An adhesive that adheres to the outer surface of the container has been proposed (for example, Patent Document 1).

  In the packaging material containing a hologram described in Patent Document 1, a hologram forming resin layer and an ink layer formed in order on a substrate are pressed using a hologram embossing roll under heating, whereby the boundary between the hologram forming resin layer and the ink layer is obtained. An uneven hologram pattern is formed on the surface and the outer surface of the ink layer. However, since this hologram pattern cannot secure the visibility of the hologram pattern if the concave and convex grooves are filled with the ink layer, it is formed in duplicate on both the boundary surface and the outer surface of the ink layer. Therefore, there is a problem that the hologram pattern cannot be recognized with an opaque ink layer, and the process for forming the hologram pattern on the back side of the transparent ink layer is complicated, resulting in a decrease in productivity.

Thus, conventionally, an ink layer has not been directly formed on the concavo-convex surface of a hologram pattern on the premise that the hologram pattern is visually recognized.

Hereinafter, a film with a hologram pattern according to an embodiment of the present invention and a manufacturing method thereof will be described in detail with reference to the drawings.
<First Embodiment>
As shown in FIG. 1D, the hologram pattern-attached film according to the first embodiment has a hologram pattern forming layer 12, an ink layer 14, and a reflective layer 16 formed in this order on the lower surface 11a of the substrate 11, and the upper surface 11b. The second ink layer 15 is formed. This film with a hologram pattern is a film in the form of a sheet, a roll film, or a label, which is used by being placed on the outer surface of a container, package or other object that contains a beverage or food. Examples of the object include metal cans, plastic containers, paper containers and packages, and containers containing aluminum.

  The base material 11 is made of a light-transmitting material, and for example, a PET (polyethylene terephthalate) film, a nylon (trademark) film, an OPP (stretched polypropylene) film, or other resin film is used.

  As shown in FIG. 1A, the hologram pattern forming layer 12 is formed on the lower surface 11a of the substrate 11 by, for example, transfer using a coating roll, spraying by spraying, or spin coating. The hologram pattern forming layer 12 is made of a material having high translucency. For example, a thermoplastic resin, an ultraviolet curable resin, or a self-curable resin is used.

  Next, as shown in FIG. 1B, a hologram pattern 13 is formed on the lower surface 12 a of the hologram pattern forming layer 12. The hologram pattern 13 is formed by, for example, pressing a separately formed matrix on the lower surface 12a of the hologram pattern forming layer 12 in an uncured state, pressing it, and peeling it off after curing. After the pressing, the hologram pattern forming layer 12 is cured and the hologram pattern 13 is fixed on the lower surface 12a by a curing method corresponding to each of the thermoplastic resin, the ultraviolet curable resin, and the self-curing material as the mother mold. .

Subsequently, as shown in FIG. 1C, an ink layer 14 and a second ink layer 15 are formed as a print design. The ink layer 14 and the second ink layer 15 are formed to have a predetermined pattern by, for example, gravure printing or flexographic printing. The ink layer 14 is directly formed on at least a part of the hologram pattern 13, and the second ink layer 15 is formed on the upper surface 11 b of the substrate 11.
Thus, even if the ink layer 14 is directly formed on the film 3 with a hologram pattern, the hologram pattern can be visually recognized, so that the restriction on the arrangement of the ink layer 14 can be reduced.

  Here, on the print design using the ink layer 14, the ink layer 14 uses at least a part of the ink except white that cannot visually recognize the hologram pattern. In addition, the ink film thickness is preferably 3 μm or less, preferably 1.5 μm or less, more preferably around 1 μm, within a range where the desired color tone can be obtained. This makes it possible to visually recognize the hologram pattern even on the print design of the ink layer 14.

  In addition, when it is not desired to develop a hologram pattern on a print design using the ink layer 14, the ink layer 14 reduces the translucency and suppresses the light from the reflective layer 16, so that a plurality of different inks are used. A configuration in which layers are stacked can also be adopted. With this configuration, it is possible to provide a wide range of translucency and design. For example, in some areas of the ink layer 14, the hologram pattern is provided with transparency so as to ensure the visibility of the hologram pattern, while in other areas, the transparency is controlled by laminating a plurality of ink layers. The visibility of the pattern 13 can also be changed.

  Next, as shown in FIG. 1D, the reflective layer 16 is formed. The reflective layer 16 is formed on the ink layer 14 in a portion where the ink layer 14 is formed, and on the hologram pattern 13 in a portion where the ink layer 14 is not formed, for example, by metal vapor deposition. Thereby, the reflective layer 16 is arranged on the side far from the substrate 11 with respect to the hologram pattern 13 and the ink layer 14. The metal material used for vapor deposition preferably has a reflectivity of visible light of 20% or more after vapor deposition, for example, aluminum.

  In order to dispose the hologram-patterned film manufactured as described above on the object, an adhesive layer is formed on the reflective layer 16, and the adhesive layer is adhered to the outer surface of the object. As the adhesive material used for the adhesive layer, a material that does not complete curing during the operation of attaching the hologram pattern-attached film to the object and can be quickly cured after the application operation is preferable. Examples of such adhesive materials include thermosetting, thermoplastic, ultraviolet curable, and self-curing materials.

  It is preferable to form a varnish layer as a topcoat layer on the upper surface of the film with a hologram pattern adhered to the object, that is, on the upper surface 11b of the substrate 11 or the upper surface of the second ink layer 15. By adopting this layer structure, the surface of the container with a hologram pattern can be given lubricity and gloss without affecting the visibility of the hologram, so that the sliding performance of the can body can be ensured, and the can making process and can manufacturing In the process, the surface of the can body can be prevented from being stained and scratched, and the productivity, decoration and design can be improved.
