The layers present in article 10 include, but are not limited to, organic layers 12, 14, reflective layer 20, magnetic layer, absorption layers 22, 24, etc. The individual layers of article 10 are disclosed more fully below. In one aspect, all of the layers of article 10 may be embossed or microstructured in other ways, for example, as shown in FIGS. 6 through 8. In another aspect, one or more of the layers of article 10 may be embossed. In a further aspect, one or more surfaces of one or more of the layers of article 10 may be embossed, for example, as shown in FIGS. 6 through 8. In yet another aspect, one or more surfaces of one or more of the layers of article 10 may be planar, for example, self-planarized, as shown in FIGS. 7 and 8. Article 10 may be symmetric, that is, it may be a bilayer having the same type and the same number of layers on both sides. The materials forming the layers of symmetric article 10 may be different. For example,

[0014] Article 10 may include a first organic layer 12, a reflective layer 20, and a second organic layer 14. ​​The material forming the first organic layer 12 is the same as the material forming the second organic layer 14, or They are different.

Figures 6 to 8 show various embossed articles 10, but the explanation is not shown. For simplicity, various multilayer articles 10 are not shown. Any article 1 in Figures 1 to 3 The 0 is intended to be embossed in any way shown in Figures 6 to 8. The description of a specific layer, such as layer 20, is applicable to any article 10 that includes that specific layer, such as a reflective layer. It is also intended that it be usable. In addition, references to layers refer to the first layer unless otherwise specified. and a second layer, for example, “organic layer”, “first organic layer 12”, and “second organic layer 14”. It is intended to be equally applicable.

[0016] Figure 1 shows a cross-section of an article 10 including a first organic layer 12, a reflective layer 20, and a second organic layer 14. The surface is shown. The first organic layer 12 and the second organic layer 14 each have an embossed interior. The embossed surface 18 and the embossed surface 18 inside the first organic layer 12 are adjacent to each other, Embossed surface adjacent to the embossed surface 18 inside the second organic layer 14 It may also include a firing layer 20. See, for example, Figures 6 to 8.

[0017] The first organic layer 12 and the second organic layer 14 may be the same or different. This is also acceptable. For example, the first organic layer 12 and the second organic layer 14 may be the same color, or They may be different colors. In one embodiment, the first organic layer 12 and the second organic layer 14 are Each may be transparent. The first organic layer 12 and the second organic layer 14 may be the same or different. It may also contain organic materials.

[0018] Although not shown in Figure 1, any surface of any layer present in article 10 is embossed. It may be processed or it may be flat. For example, the first organic layer 12 and the second The organic layer 14 is located inside the surface adjacent to the reflective layer 20, as shown in Figures 6 to 8. The reflective layer 20 in Figure 1 may include, for example, each surface Embossed surface 18 inside the first organic layer 12 and embossed surface 18 inside the second organic layer 14 The surface adjacent to the bossed surface may be fully embossed.

[0043] Article 10 disclosed herein is formed using at least two different methods. This is also good. In one embodiment, as shown in Figure 4A, the first organic layer 12 is coated onto the substrate 26. A method for producing an article 10 such as a diffraction pigment is disclosed, which includes the process of diffracting a first organic layer 1. Item 2 may be coated using a liquid coating process. This allows the first organic layer 12 to self-planarize, thereby creating a flat external surface. The reflective layer 20 is provided. The reflective layer 20 is subjected to any deposition process including vacuum deposition and liquid coating.

Layers formed using the liquid coating process of this disclosure have improved light It is thought that this will demonstrate academic performance.

[0048] As shown in Figure 4D, this method involves peeling off the base material 26, thereby forming the article 10. This may further include: In one embodiment, the substrate 26 may include a release layer 28. 28 may have lower adhesion to the first organic layer 12 compared to the substrate 26. In this embodiment, the release layer 28 is soluble and may be removed.

In one embodiment, the substrate 2 6 may be cooled to embrittle the associated delamination layer 28, if present. Another embodiment Therefore, the peeling layer 28 is subjected to, for example, photonic or electron beams to increase the degree of crosslinking. It may be embrittle by heating and / or hardening with energy, thereby peeling Separation becomes possible. Next, the vapor-deposited layer is sharply bent or brushed on the surface. The peeled layer may be mechanically removed. The peeled layer may be made into flakes, foils, or using well-known techniques. These may be sized into articles 10 such as optical devices in sheet form.

[0050] This method involves applying a cooling drum to an embossed layer (reflector / first organic layer 12). This may further include removing the heat provided by the embossing roller / plate. Embossing involves applying diffraction patterns, holograms, symbols, logos, or any other design to a deposited layer. This can provide an appropriate microstructure.

[0051] The substrate 26 is made of a heat-resistant material such as polyester, polyamide, polyvinyl chloride, or propylene. Materials may be included. The substrate 26 may be present in a roll configuration, and as a result, article 10 The layers are deposited on the substrate 26 as it moves from the unwinding to the unwinding roll configuration. The substrate 26 is made of a material having a softening temperature higher than the softening temperatures of the multiple layers such as the organic layers 12 and 14. It may include the following. The substrate 26 may be formed of a flexible material. The substrate 26 during the manufacturing process It may be any suitable material capable of accepting multiple layers deposited on it.

The substrate is The thickness can be varied, for example, from about 2 μm to about 100 μm, and as a further example, about 10 μm. The range may be approximately 50 μm.

[0052] In one embodiment, a method for manufacturing article 10 is also disclosed, as shown in Figures 5A to 5E. The method involves optionally coating a first organic layer 12 onto a substrate 26 that includes a release layer 28. It may also include the first organic layer 12, which is coated using a liquid coating treatment. This may also be done. As shown in Figure 5B, this method involves applying the coated first organic layer 12 to the environment. This may also include bossing to create an internal embossed surface 18. The method includes depositing a reflective layer 20 on an internally embossed first organic layer 12. That's fine. In this way, the reflective layer 20 is embossed as shown in Figure 5C. It corresponds to the embossed surface 18 inside the first organic layer 12.

[0053] As shown in Figure 5D, this method involves coating a second organic layer 14 onto the deposited reflective layer 20. The process may further include coating. The second organic layer 14 is coated using a liquid coating treatment. It may be coated.

[0054] As shown in Figure 5E, the substrate 26 and any release layer may be removed from the article 10.

[0055] In one embodiment, the method involves embossing the first organic layer 12, followed by depositing the reflective layer 20. This may also include depositing a second organic layer 14. By this method, the material shown in Figure 6 Product 10 is obtained. Alternatively, this method involves depositing a first organic layer 12 and a reflective layer The process involves depositing layer 20 and embossing both the first organic layer 12 and the reflective layer 20. The method may also include depositing a second organic layer 14. Article 10 is opposite to Article It has different modulation on the outer surface of one side. Thus, the degree of modulation on the outer surface of the opposite side Because the degrees are different, article 10 is asymmetric. Statistically, the second organic is less modulated. 50% of the article 10, such as flakes having layer 14, are facing upwards, and more modulated first 50% of the article 10 having the organic layer 12 faces upward, providing a different diffraction effect. 8 can also be considered asymmetric because the degree of modulation on the opposite external surface is different. Figure 7 can be considered symmetrical.

[0056] Additionally or alternatively, articles 10 in the form of flakes, sheets, or foils may be hard-coated. Alternatively, a protective layer may be included. In some examples, these layers (hard coat or protective layer) It does not require optical quality.

[0057] Depending on the thermoplastic properties of article 10 and release layer 28, the embossed layer will peel off from the substrate 26. It may be included between layer 28. This embossed layer may be part of article 10. In one embodiment, the release layer 28 is removed or between the substrate 26 and the embossable layer. It is also used in introductions.
