OVI Color Pigments Formulation

OVI Color Pigments Formulation represent a highly specialized class of security pigments that exhibit color-shifting effects based on the angle of observation or illumination. These pigments are widely used in anti-counterfeiting applications, especially in the banking, currency, identity card, passport, and brand protection industries. As demand for authentication and security features grows, the formulation of high-performance OVI systems has become both a scientific challenge and a commercial necessity. \n \nThis book, ÒOVI Pigment Formulations,Ó is a comprehensive guide for chemists, formulation scientists, coating technologists, and ink manufacturers who seek to understand and develop optically variable inks from the ground up. It provides detailed insights into theory, pigment selection, binder compatibility, formulation techniques, and application methods to create robust and durable OVI systems suitable for screen, gravure, flexo, and offset printing. \n \nKey Topics Covered \n
