The use of colour-shifting films and inks is well-established in the security printing market and accordingly offers secure and easy-to-use first level authentication to the public. Further, the use of these coatings is becoming increasingly prevalent in commercial products which include packaging, toys, and cars. This widespread use, however, makes it imperative to develop differentiated next-generation materials in order to stay well ahead of casual and professional counterfeiters.

变色薄膜和油墨的使用在安全打印市场上已经很成熟，因此为公众提供了安全和易于使用的一级认证。此外，这些涂料在包括包装、玩具和汽车在内的商业产品中的使用正变得越来越普遍。然而，这种广泛的使用使得开发差异化的下一代材料变得势在必行，以便远远领先于临时和专业的造假者。
