Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 and fig. 6, the multi-color dynamic color-changing film provided in the embodiment of the present invention sequentially includes a base film layer 11, a structure layer 12, a plate resonance structure with a specific color-changing effect, and a color layer 16 for changing the color presented by the plate resonance structure to achieve a stronger color-changing effect. The structure layer 12 has a micro-nano structure 121 with a dynamic laser effect on the side far away from the base film layer 11.

The material of the base film layer 11 may be a flexible film, such as a polyester-based film, but not limited thereto, and the thickness thereof is 10-150 um. Preferably, the thickness of the base film layer 11 is 12 to 100 μm. The base film layer 11 serves as a support layer for the other layers and may increase the flexibility of the multicolor dynamic color changing film.

The micro-nano structure 121 of the structure layer 12 is a graphic structure formed by a cylindrical lens or an opposite collision light column or a sand point light column, and the graphic structure can realize a dynamic laser effect. Meanwhile, the color changing effect of the panel resonance is combined, so that the product not only presents rich dynamic colorful light color changing effect, but also has extremely high anti-counterfeiting property. When the observation angle is converted, an obvious color conversion effect can be presented, the patterns are shown, hidden or replaced along with different visual angles, and a moving picture or a custom effect of the same pattern can be displayed.

The micro-nano structures 121 in the structure layer 12 are different, and the light and shadow effects thereof are also different, as described in detail below.

As shown in fig. 2, the cylindrical lens includes a plurality of strip-shaped structures 1211, the strip-shaped structures 1211 are arranged according to a fresnel rule, the cross-section of the strip-shaped structures 1211 is spherical, and the spherical curvatures of the strip-shaped structures 1211 decrease in sequence; the dynamic light and shadow effect perpendicular to the tangential direction of the arc line is generated by the arc line shaped columnar (cylindrical lens) structure array.

As shown in fig. 3, the light impinging column includes a plurality of grating units 1212, and two adjacent grating units 1212 are arranged in a mirror image. Each grating unit 1212 includes a plurality of first micro-nano sub-structures 12121 and second micro-nano sub-structures 12122 with different orientation angles and same or different periods; the first micro-nano structure 12121 and the second micro-nano structure 12122 are arranged in an array. Due to the symmetry of two adjacent grating units 1212, the dynamic shadow exhibits a phase-to-phase motion effect as the angle is rotated.

As shown in fig. 4, the sand point light column includes a third micro-nano sub-structure 1213 and a fourth micro-nano sub-structure 1214 with different orientation angles and the same or different periods; the third micro-nano sub-structure 1213 and the fourth micro-nano sub-structure 1214 are nested with each other. Therefore, the third micro-nano sub structure 1213 and the fourth micro-nano sub structure 1214 form points in the structure layer 12, and all the points are randomly distributed to form a light column effect with a certain period, so that the light column dynamic light shadow with a sand point effect is visually presented.

In other embodiments, the third micro-nano sub-structure 1213 is adjacent to the second micro-nano sub-structure 1214, so that it can also visually present a light pillar dynamic shadow with a sand dot effect.

The panel resonance structure includes a first transparent medium layer 13, a second transparent medium layer 14, and a third transparent medium layer 15 in this order. The first transparent medium layer 13, the second transparent medium layer 14 and the third transparent medium layer 15 are all prepared by adopting a vacuum evaporation process or a vacuum sputtering process. The first transparent medium layer 13 is prepared on the surface of the structure layer 12 on the side with the micro-nano structure 121, and the first transparent medium layer 13 has a structure corresponding to the micro-nano structure 121 on the structure layer 12; the second transparent medium layer 14 is prepared on the lower surface of the first transparent medium layer 13; the third transparent medium layer 15 is prepared on the lower surface of the second transparent medium layer 14. Therefore, one surface of the first transparent medium layer 13, the second transparent medium layer 14 and the third transparent medium layer 15 is formed along the surface of the structure layer 12 with the micro-nano structure 121, and the other surface is complementary to the surface of the structure layer 12 with the micro-nano structure 121.

The structure is based on the slab waveguide resonance principle, and realizes the expression of colors: standing wave resonance occurs when the incident wavelength changes at different observation angles, and color conversion is realized, namely, the color changes along with the change of the observation angle. Wherein, the first transparent medium layer 13 is made of titanium dioxide or zinc sulfide, and the thickness thereof is 10-80 nm; the second transparent dielectric layer 14 is made of magnesium fluoride, the thickness of the second transparent dielectric layer 14 is 150nm-650nm, and preferably, the thickness of the second transparent dielectric layer 14 is 200 nm-400 nm; the third transparent dielectric layer 15 is made of titanium dioxide or zinc sulfide, and the thickness of the third transparent dielectric layer is 10-80 nm. The color expression is realized by designing the materials of each layer or/and different thicknesses in the first transparent medium layer 13, the second transparent medium layer 14 and the third transparent medium layer 15, and the presented color changes along with the increase of the thickness and the change of the observation angle (incidence angle).

In practical applications, the refractive index of the first transparent medium layer 13 and the refractive index of the third transparent medium layer 15 are both greater than the refractive index of the second transparent medium layer 14. Wherein, the refractive index of the second transparent medium layer 14 is 1.38-1.51.

The color layer 16 is provided with at least 1 color area. When the number of the color areas is 1, the color areas are full-page single colors; when the number of the color areas is plural, the different color areas are adjacent or spaced, that is, the different color areas in the color layer 16 correspond to the pattern required by the product, thereby giving the product more flexible design.

In the present embodiment, the color layer 16 has a dark color, such as black, dark purple, dark blue, etc.; the thickness of the color layer 16 is 0.1 um-20 um; preferably, the thickness is 1um to 10 um. The color layer 16 is made of nano-scale ink. Because when changing observation angle, resonant frequency can take place to remove, makes the utility model discloses a colorful dynamic color-changing membrane possesses the effect of discolouing simultaneously. Therefore, the superposed color layer 16 is used for absorbing colors with different wavelengths and changing the wavelength of the final reflected light, so that the color presented by the original flat-plate resonance structure is changed, a stronger (i.e., darker) color change effect is realized, the visual sense is enhanced, and the anti-counterfeiting effect is further enhanced. Meanwhile, the complex dynamic graphic color changing effect is realized by combining the dynamic laser effect of the micro-nano structure 121 on the structural layer 12.
