发明名称 USE OF PEARLESCENT AND OTHER PIGMENTS TO CREATE A SECURITY DOCUMENT
摘要 A security material for documents comprises a first layer of material, such as a polymeric film or laminate, having first and second sides. A pearlescent material is applied to at least one of the first and second sides. The pearlescent material defines a pattern comprising at least two different colors that are at least partially interlocked in the pattern, and the pattern permits printed information that is overlaid by the pattern to be effectively perceived.
