Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, a three-dimensional dynamic anti-counterfeiting product with a plurality of anti-counterfeiting patterns includes a surface protection layer 1, a support layer 2, glass beads 3, a focus forming layer 4, a reflective layer 5, an adhesive layer 6, a protective paper 7 and a printing Layer 8.

[0028] The surface protection layer 1 is a light-transmitting smooth film-like resin layer or a frosted film-like resin layer, consisting of 100 parts by weight of acrylic resin solution, 16 parts by weight of methylated melamine resin solution, and 6 parts by weight of cellulose derivatives. , 1.5 parts by weight of UV absorber, 0.05 parts by weight of leveling agent, 0.12 parts by weight of catalyst and 16.7 parts by weight of methyl isobutyl ketone / toluene solution in a mixing ratio of 8 / 2 are coated on the engineering substrate film formed after drying.

[0029] The surface protection layer 1 is pasted on the support layer 2, and the s...

Embodiment 2

[0041] In this embodiment, the basic structure of the anti-counterfeit product is the same as that in Embodiment 1, and will not be repeated here, except that the reflection angle produced by laser irradiation is different.

[0042] There are 4 anti-counterfeiting patterns irradiated by laser light on the glass beads 3, the focus forming layer 4, the reflective layer 5 or on one of them, each anti-counterfeiting pattern has an independent reflection angle, and every two adjacent reflection angles are separated by 5 ° above. Such as image 3 As shown, the reflection angles of the four anti-counterfeiting patterns are respectively set to -30°, 0°, +15°, +45°.

Embodiment 3

[0044] In this embodiment, the basic structure of the anti-counterfeit product is the same as that in Embodiment 1, and will not be repeated here, except that the reflection angle produced by laser irradiation is different.

[0045] There are 5 anti-counterfeiting patterns irradiated by laser on the glass beads 3, the focus forming layer 4, the reflective layer 5 or one of them, each anti-counterfeiting pattern has an independent reflection angle, and every two adjacent reflection angles are separated by 5 ° above. Such as Figure 4As shown, the reflection angles of the five anti-counterfeiting patterns are respectively set to -60°, -30°, 0°, +30°, +60°.

Abstract

The invention discloses a three-dimensional dynamic anti-fake product with multiple anti-fake patterns. The three-dimensional dynamic anti-fake product comprises a surface protection layer, a supporting layer, micro glass beads, a focus point forming layer, a reflecting layer, a bonding layer and protection paper. The surface protection layer is pasted to the upper portion of the supporting layer, the focus point forming layer is arranged below the supporting layer, the micro glass beads are arranged between the supporting layer and the focus point forming layer, the bonding layer is arranged below the supporting layer, the protection paper is pasted to the lower portion of the bonding layer, and lasers irradiate the micro glass beads, the focus point forming layer and the reflecting layer or one of the micro glass beads, the focus point forming layer and the reflecting layer to form the three to six anti-fake patterns. The three-dimensional dynamic anti-fake product is novel in structure, lasers irradiate the micro glass beads to form the floating anti-fake patterns, the patterns change along with viewing angle changes, a strong dynamic feeling is sensuously achieved, recognition is facilitated, meanwhile, the anti-fake intensity is improved, and the three-dimensional dynamic anti-fake product is not likely to be counterfeited or copied, and can be applied to the fields of traffic signs, license plates, anti-counterfeit labels and other fields needing security.

Description

technical field [0001] The invention relates to the technical field of reflective sheets, in particular to a three-dimensional dynamic anti-counterfeiting product with multiple anti-counterfeiting patterns. Background technique [0002] Reflective sheets are widely used in automobile license plates, road signs and certification labels due to their excellent nighttime visibility. However, there are many counterfeit reflective sheet products on the market. Anti-counterfeiting technology to prevent counterfeit reflective sheet products, such as using laser radiation to make patterns, LOGO, characters, etc. on the reflective sheet is one of the anti-counterfeiting technologies. Counterfeiting or imitation has brought a lot of trouble to manufacturers and consumers. Contents of the invention [0003] In order to solve the problems of simple structure, single anti-counterfeiting pattern and easy counterfeiting of the existing reflective sheet, the present invention adopts the f...
