Abstract Optically variable pigment technologies for markings and inks have increased in use as overt protection methods for document and product security. These technologies utilize optical reflective effects including interference technologies that create angular dependent color changes. Novel developments in different inorganic and organic pigments offer potentially new optical performance for both overt and covert security applications. These developments may lead to unique signature pigment formats that can verify origin and authenticity. This article summarized optically variable pigment’s manufacturing, application and development.
