[0004] The patent of CN101701129A provides a high wear-resistant and anti-fingerprint coating, which uses fluorine-containing acrylate monomer and nano-powder to obtain the anti-fingerprint performance of the coating, but the reaction speed of monofunctional fluorine-containing acrylate monomer is slow, and it is easy to reduce the overall composition of the formula. Curing speed, narrow process adaptability, and the coating uses nano-powder, which is difficult to disperse, poor stability, and high cost
The patent literature of CN201010533818 mentions a fluorine-containing coating, which can form a 10-100nm anti-fingerprint coating on the surface of the product, but the coating has low hardness and is not a UV light curing system
CN101891991A discloses a high-hardness anti-fingerprint coating and its preparation method, which mainly acts on the metal surface, and adopts fluorocarbon resin and nanoparticles to obtain a coating with better hydrophobicity, but this system is not UV-curable, and mainly functions with Metal substrate, not suitable for plastic substrates such as PET
