The banknote 1 has a substantially planar structure and includes a flexible sheet-like substrate 2 made of a transparent plastic material. The substrate 2 is covered by opaque layers 3 and 4 on most of the upper and lower surfaces. As shown in Fig. 1, the opaque layer is not applied to the entire surface of the sheet-like substrate 2, so that the opaque Z portion 5 of the substrate is left at least partially covered by the opaque layers 3 and 4. Such a transparent and transparently uncovered portion 5 constitutes a "window" of a banknote through which light can be transmitted. The substrate 2 of transparent plastic material is preferably made of a transparent polymeric material, which can be made of at least one double Axis oriented film. The substrate includes a single layer of X polymer material film. In addition, the substrate may include a laminate of two or more transparent biaxially oriented conjugate films.

For example, the opaque ink layer contains an added pigment coating containing a pigment such as titanium dioxide dispersed in a binder or carrier of a heat-activatable crosslinked polymer material. In addition, a transparent plastic material substrate 2 Can be placed between layers of opaque paper to be printed or otherwise applied. Although the banknote shown in Figure 1 is shown with an opaque layer applied to the upper and lower surfaces', in other embodiments of the present invention, the banknote is only -An opaque layer is applied on the surface.

Description of the invention (4-second section 8. The diffraction structure is formed in the first and second sections 7 and 8. In particular, each area is combined with a transmission diffraction structure such as a diffraction grating to form a microscope ⑽ ㈣ The pattern. The diffraction structure formed in the 7th section and the grating structure formed in the * A ί and _ diffraction structure have a side view and a line interval or periodic selection. Therefore, it refers to the transmission through the transmission winding. At least the -th-spectral component of the polychromatic light with a diffractive structure. The M ′ of each of the two sections 7 and 8 is selected 'so the different spectral components of the polychromatic light transmitted by the banknote i through the window are diffracted, while the rest are not diffracted. The spectral components are projected from each diffraction structure to produce visually distinguishable colors, which together form a projection-preserved image. The various diffraction structure features of the first and seventh sections 7 and 8 such as the line spacing of the grating structure, side views And the depth can be selected to precisely define the spectral components of the polychromatic light to be diffracted. Although the specific embodiment of the security object shown in Figure 1 includes a diffractive light filter having two sections, each of which includes a different diffractive junction However, in other implementations of the present invention, only one such section of a single diffraction structure is used. Similarly, three or more sections each having a separate diffraction structure can be used in other specific embodiments. Ministry of Economic Affairs Figures 2 and 3 printed by the Intellectual Property Bureau's Consumer Cooperative show that the authenticity of the banknote can be verified by the user. As shown in Figure 2, the user can place the banknote directly in front of an appropriate multi-color light source. For example, in transparent Window 5 with diffractive light filter banknote 丨 can be placed back to the video display terminal (VDT) screen 10. The VDT screen contains red, green and blue (RGB) pixel arrays, which respectively project the multi-color light emitted by the screen Red, green, and blue spectral components. This paper scale applies Chinese National Standard (CNS) A4 specifications (210 X 297 public love) M7146 A7 B7 V. Description of the invention (5 In other specific embodiments, different multi-color light sources can be used, such as A white source such as a light box. It is preferable to use a light source with a coverage area greater than: the area of the light beam and the mirror area, and it will produce at least two spectral components that can be separated. Y can also be used as itself. Color light source. For example, the banknote 1 can be folded so that the multi-color surface overlaps the transparent window 5. Then the surrounding light is reflected by the multi-color surface of the banknote 1 and transmitted through the diffractive light filter 6 of the transparent window 5. In the configuration shown in FIG. 'The light emitted by the light source 10 is emitted outward toward the user 11, and the user is located at the angle of view of the banknote 1, which in this case is the vertical plane of the banknote. In this example,' the first in the diffraction filter 5 Section 7 forms the _th diffractive structure. If it is used to diffract the red and green light of the multi-colored light transmitted through the substrate 1 of the banknote 2 ^ | tj components, then passes through the section 7. The diffractive structure features are selected ^ ' Therefore, the red and green spectral components are turned at least at an angle of 0. Similarly, the second diffraction structure formed on the second section 8 of the diffractive light filter 6 acts on: the VDT screen 10 is at least at an angle θ The green and blue spectral components of the emitted polychromatic light. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed such that only the blue spectral component of the light emitted by the VDT screen is transmitted to the user 11 through the first section 7, and only the red spectral component of the polychromatic light from the VDT screen is transmitted by the second Segment 8 is transmitted to user U. The colors transmitted by the sections of the diffractive light filter 6 are selected so that the colors transmitted by one section can be visually distinguished from the colors transmitted by the other sections. In this way, the colors from the various sections of the diffracted light / mirror can be combined to form at least a part of the projected security image (schematically shown as "S", the font is shown in Figures i, 2 and 3) (CNS) A4 specifications (210 X 297 public love) 567146

Referring again to FIG. 1, the uncovered section 13 may remain around at least a part of the window 5 of the diffractive light filter 6. This uncovered section 13 allows the entire spectral component of the multicolor light emitted by the vDT screen 10 to be transmitted to User 丨 1. This makes it easier for the user 11 to distinguish between unfiltered light transmitted through the uncovered portion 13 and unfiltered light transmitted through the diffractive light filter 6.
