MICRO-OPTIC MATERIAL WITH IMPROVED ABRASION RESISTANCE

摘要

A micro-optic material that demonstrates improved abrasion resistance while continuing to provide optimal optical performance is provided. An outermost layer of the micro-optic material is prepared from a formulation utilizing an effective amount of one or more nanocomposites {e.g., a silica-polymer nanocomposite, an alumina-polymer nanocomposite). The inventive material, which offers easily recognized dynamic optical effects, is suitable for use in high wear end-use applications, such as rigid ID cards, which have heightened performance requirements.
