Description

Technical field [0001] The invention relates to a functional anti-counterfeiting coating product, in particular to a high-molecular polymer material for anti-counterfeiting and a preparation method thereof. Background technique [0002] Functional anti-counterfeiting coating products, including aluminum-plated anti-counterfeiting holographic film, transparent anti-counterfeiting holographic film, anti-counterfeiting holographic hot stamping foil, etc. They use polyester polymer plastic films, such as BOPP, PET, etc., all of which have thermoplastic properties. When warm and pressurized, the interference fringes of the image recorded on the holographic molded plate can be transferred to its surface. These fine relief-like fringes carry the light wave intensity and phase information of the object. This type of molded hologram needs to be observed by sunlight Reproduce the image. Since the light of each wavelength in the white light will be diffracted by interference fringes, and th...
