Description

Technical Field

[0001] This application relates to the field of anti-counterfeiting hinge technology for passport data pages, and in particular to an anti-counterfeiting hinge for connecting PC passport data pages. Background Technology

[0002] In existing technologies, it is impossible to prevent counterfeiting of passport information pages during use, and it is also impossible to identify the passport under light, thus affecting the usability. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, which cannot prevent the passport data page from being counterfeited or to enable light-based identification of the passport during use, thus affecting the usability. Therefore, this invention proposes an anti-counterfeiting hinge for connecting PC passport data pages.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An anti-counterfeiting hinge for connecting data pages in a PC passport includes:

[0006] Anti-counterfeit hinge body;

[0007] A fluorescent material layer is fixedly installed inside the top side of the anti-counterfeiting hinge body;

[0008] A laser-sensitive coating is fixedly installed at the bottom of the fluorescent material layer;

[0009] An optically variable material layer is fixedly installed on the bottom of the laser-sensitive coating;

[0010] The anti-counterfeiting layer is fixedly installed at the bottom of the optically variable material layer.

[0011] Preferably, a UV fluorescent ink layer is fixedly installed at the bottom of the anti-counterfeiting layer, and a thermochromic coating layer is fixedly installed at the bottom of the UV fluorescent ink layer.

[0012] Preferably, a printing layer is fixedly installed on the bottom of the thermochromic coating, and a nano-silica hardening coating is fixedly installed on the bottom of the printing layer.

[0013] Preferably, a microtext or pattern layer is fixedly installed on the bottom of the nano-silica hardened coating, and a multilayer composite TPU film layer is fixedly installed on the bottom of the microtext or pattern layer.

[0014] Preferably, an adhesive layer is fixedly installed at the bottom of the multilayer composite TPU film layer, and a PET substrate is fixedly installed at the bottom of the adhesive layer.

[0015] Preferably, a wear-resistant coating is fixedly installed on the bottom of the PET substrate, and a waterproof layer is fixedly installed on the bottom of the wear-resistant coating.

[0016] Preferably, a flame-retardant layer is fixedly installed at the bottom of the waterproof layer.

[0017] The beneficial effects of the anti-counterfeiting hinge for connecting PC passport data pages in this utility model are as follows:

[0018] Thanks to the inclusion of a fluorescent material layer, an optically variable material layer, and a laser-sensitive coating, the passport exhibits a consistently low fluorescence level under ultraviolet light. It also enables Level 2 anti-counterfeiting functionality with laser-engraved tactile characters, facilitating rapid authentication. Based on coaxial optical film technology, it supports laser etching of personalized information, achieving color-changing effects for Level 1, 2, and 3 anti-counterfeiting features. This allows the hinge area to exhibit dynamic optical changes under different lighting conditions, enhancing anti-counterfeiting performance.

[0019] Due to the inclusion of a UV fluorescent ink layer, a thermochromic coating, a nano-silica hardening coating, and a microtext or pattern layer, it emits a specific wavelength spectrum under ultraviolet light, supporting optical detection of concealed codes. The use of spiropyran derivative ink triggers molecular structure changes when the temperature exceeds a threshold, enabling pattern visibility switching. The nano-silica hardening coating is coated with a SiO2 nanoparticle dispersion (particle size 20-50nm), achieving a surface pencil hardness ≥3H and a 5-fold increase in wear resistance. Application effects include enhanced scratch resistance and weather resistance. The microtext or pattern possesses extremely high precision and is difficult to replicate, serving as an anti-counterfeiting mark. Through laser etching or high-precision printing technology, microtext or patterns can be embedded in the hinge surface or internal layers. This micro-information is only clearly visible under a magnifying glass, effectively preventing counterfeiting.

[0020] By incorporating multiple layers of composite TPU film, adhesive layer, waterproof layer, and flame-retardant layer, and enhancing the flexibility and durability of the hinges, the multi-layer composite TPU film layer prevents data pages from delaminating, avoids passport damage and tampering, and integrates various anti-counterfeiting features. It can exhibit dynamic optical changes or hidden patterns under different lighting conditions, providing a high level of anti-counterfeiting protection for passports. High-strength adhesives, such as epoxy resin or polyurethane, ensure strong interlayer bonding. A nano-silica hardening coating increases surface hardness. A PET / UV varnish film layer prevents moisture penetration. If fire-retardant properties are required, flame-retardant materials can be added.

[0021] This invention can prevent counterfeiting of passport information pages during use and can identify the passport under light, thus improving the usability. Attached Figure Description

[0033] Anti-counterfeiting layer 4 is fixedly installed at the bottom of optical variable material layer 3. The outermost layer is anti-counterfeiting layer 4, which uses UV special fluorescent ink to achieve anti-counterfeiting verification of the material under ultraviolet light.

[0034] In this embodiment, a UV fluorescent ink layer 5 is fixedly installed at the bottom of the anti-counterfeiting layer 4. The UV fluorescent ink layer 5 contains fluorescent materials with europium / terbium rare earth elements, which emit a specific wavelength spectrum under ultraviolet light to support optical detection of covert codes. A thermosensitive color-changing coating 6 is fixedly installed at the bottom of the UV fluorescent ink layer 5. The thermosensitive color-changing coating 6 uses spiropyran derivative ink, which triggers changes in molecular structure when the temperature exceeds a threshold, thereby achieving pattern visibility switching.

[0035] In this embodiment, a printing layer 7 is fixedly installed at the bottom of the thermochromic coating 6. The printing layer on the substrate enables the display of images and text under normal light. A nano-silica hardening coating 8 is fixedly installed at the bottom of the printing layer 7.

The microtext or pattern has extremely high precision and is difficult to replicate, and can be used as an anti-counterfeiting mark. Through laser etching or high-precision printing technology, microtext or patterns are embedded in the hinge surface or inner layer. These micro-information can only be clearly seen under a magnifying glass, effectively preventing counterfeiting. A multi-layer composite TPU film layer 10 is fixedly installed at the bottom of the microtext or pattern layer 9 to enhance the flexibility and durability of the hinge, prevent the data page from delaminating, avoid passport damage and leaving traces of tampering. The multi-layer composite TPU film layer 11 can integrate a variety of anti-counterfeiting features and can present dynamic optical changes or hidden patterns under different lighting conditions, providing a high level of anti-counterfeiting protection for the passport.
