For this reason, book covers and labels using holograms are widely used. In addition, many inventions for reproducing these holograms (mass duplication) (Patent Documents 1 to 5 below) have been proposed.

FIG. 3 is an enlarged cross-sectional view of the fabric in each process for explaining the manufacturing process.

The material of the cloth hologram substrate 1 according to the present invention (an enlarged cross-sectional view is shown in FIG. 3A) is a resin transparent to ultraviolet rays or electron beams. The substrate 1 is long, visually transparent, and carries a hologram on the surface. This substrate 1 is a substrate in which hologram information is recorded on a transparent film surface by deformation of irregularities by any of the methods described in the aforementioned patent documents.
The fabric according to the present invention manufactured from the substrate 1 is shown in FIG. 3C, and a transparent uneven thin film layer 2 suitable for reproducing a hologram is formed on the surface of the hologram substrate 1 (FIG. 3). (See (B)). A pattern forming portion 3 made of a resin pattern is locally formed on the transparent uneven thin film layer 2. The pattern forming portion 3 is formed as a geometric pattern for the purpose of decoration, and the geometric pattern is a geometric pattern related to a regular repeating pattern of a well-known figure and a specific background printing to be expected. .

The manufacturing process of the dough is as follows, and will be described mainly with reference to FIGS.
(Step of preparing hologram substrate)
The substrate 1 is a resin substrate that is transparent to ultraviolet rays or electron beams, and can be easily prepared by using a hologram original plate, as shown in the numerous patent documents mentioned above.
(Step of applying a resin for forming a transparent uneven thin film layer)
The hologram substrate 1 is a long transparent film and is held on a reel (not shown). The hologram substrate 1 is supplied from the left side as shown in FIG. 1 and is guided between the first cylinder 12 and the impression cylinder 14 by a roller or the like. The
The first cylinder 12 is an intaglio plate, and a coating material 16 made of a transparent resin is coated on the surface thereof, and is uniformized by a blade-shaped doctor 13 and coated on the lower surface of the substrate 1. The state in which the coating material 16 is applied to the substrate 1 and the transparent uneven thin film layer 2 is formed is shown enlarged in the central part of FIG. 1 and FIG.
(First drying step)
The substrate 1 on which the very thin transparent concavo-convex thin film layer 2 is applied is guided to a dryer 15 by a roller or the like and dried, and as shown in FIG. The uneven layer 2 is formed. This substrate is guided to the left side of FIG. 2 via a roller or the like (not shown).

(Pattern resin application step)
The substrate 1 on which the transparent uneven thin film layer 2 is formed is guided between the second cylinder 22 and the impression cylinder 24 by a roller or the like as shown in FIG.
The second cylinder 22 is an intaglio and has a large number of circular recesses on the surface.
The coating material 26 is applied to the surface, and the blade-shaped doctor 23 holds the coating material 26 uniformly in the recess, and is partially applied to the surface of the transparent uneven thin film layer 2 on the lower surface of the substrate 1 (right side in FIG. 2). (See the enlarged view).
(Second drying step)
The substrate 1 is transported to a second dryer 25, where the applied resin is dried and solidified, and a pattern forming portion 3 including a large number of convex portions continuous on the surface is provided (see FIG. 3C).

The main materials used in the above-described examples are as follows.
Hologram substrate 1 Ready-made hologram film: Polypropylene (OPP)
Thickness 20μ
Transparent uneven thin film layer 2 Special base: Cationic polymer resin monomer and photoinitiator (UV curing agent)
Pattern formation part 3 Special resin: Silicone resin
Thickness several μ
The hologram substrate 1 may be thickened up to about 50 μm.

Next, a method of using the patterned hologram fabric manufactured as described above will be described with reference to FIG. FIG. 4 is an enlarged cross-sectional view showing the relationship between the fabric and the replicated product in each step for explaining the method of using the fabric according to the present invention.
(Step of preparing the board to be decorated)
The substrate 5 to be decorated is, for example, a printed label or a book cover.
(Resin application step)
An ultraviolet or electron beam curable resin 7 is applied on the substrate 5. This state is shown in FIG. The applied resin has fluidity.
(Pressing step)
The pattern forming portion 3 made of the resin pattern of the patterned hologram fabric (1, 2, 3) is pressed against the application surface of the resin 7. As a result, the resin in the portion corresponding to the pattern forming portion 3 (portion 8 in FIG. 4C) is eliminated. The transparent uneven thin film layer 2 is adhered to the surface of the remaining resin 7.
(Resin curing step)
In the pressure contact state, the resin 7 is cured by irradiating ultraviolet rays or an electron beam from the substrate 1 side of the fabric. This state is shown in FIG.
(Peeling step)
After the resin 7 is cured in the resin curing step, the patterned hologram fabric (1, 2, 3) is peeled off. The cured resin is shown in 7h. This state is shown in FIG. A hologram is duplicated on the surface of the cured resin 7h. Since the hologram is not duplicated on the exposed surface 8 of the substrate 5 to be decorated, the portion does not have the ability to reproduce the hologram and is visually recognized as a normal pattern. Note that the peeled fabric can be used repeatedly.

  The example described above shows only the cross-sectional shape, but the cross-section assumes a circular repetitive pattern. The duplicate will have a large number of circular hologram reproducible parts and hologram replay parts. This pattern portion can be a unique pattern of the reproduction product provider, or can be variously changed in relation to the use of the reproduction product or the printing of the substrate.

  FIG. 5A shows a plan view of a replicated product including a star-shaped pattern expression portion and a hologram film pattern expression portion by special resin coating (pattern portion 3 of the fabric). FIG. 5B is an enlarged perspective view showing details of the duplicate product. In FIG. 5 (B), 7h is a hologram film pattern expression part, and 8 is a pattern expression part in special resin coating. If printing is performed on the surface of the substrate 5, the portion 7 h becomes a display portion affected by the hologram, and the printing surface is directly displayed on 8.

Conventionally, it was only transferred and copied to an external stimulus curable resin (UV, EB effect resin) coated on the upper surface of the printed material. However, when creating an original instead of a ready-made hologram, there is a risk in terms of cost. Will bear.
According to the present invention, an arbitrary pattern can be easily added to a film using a ready-made hologram film. Furthermore, the present invention can easily produce a characteristic hologram film. Therefore, it can be widely used in each field of the printing industry.
