Multiple reversible color change microcapsule anti-counterfeiting material and preparation method and application thereof

The invention discloses a multiple reversible color change microcapsule anti-counterfeiting material and a preparation method and applications thereof. The preparation method comprises the following steps: dissolving at least one of temperature-sensitive material, humidity sensitive material, ultraviolet excited fluorescence material and infrared excited fluorescence material in high boiling point solvent containing UV resistant agent and antioxidant, then adding emulsifier and protective colloid to obtain emulsion solution, and adopting the in-situ polymerization method to obtain the anti-counterfeiting material with microcapsule structure. The microcapsule structure of the invention can isolate the air and the wall of the microcapsule can reduce the light transmission, thus improving the weather resistance and light resistance of the anti-counterfeiting material and prolonging the use validity of the product. The material is a microcapsule aqueous solution so that the material is completely applicable to the coating method of the currently existing water-based paint, removes apprehensions in areas of safety, health and environmental protection, thoroughly solves the defect of the complicated solvent-based (oily material) coating and processing method, satisfies the anti-counterfeiting demand and can be applied in papers, cloth and film materials in large.
