Document Type and Number:

WIPO Patent Application WO2003098188

Kind Code:

Abstract:

Microstructured taggant particles, their applications and methods of making the same are described. Precisely formed taggant particles can be formed, in the range of 500µ and smaller, from either inert polymers or biodegradable materials bearing information indicia, such as through specific shape, size, color, reflectively, refractive index, surface geometry, imprinting, optical effect or properties, and electromagnetic properties, to uniquely tag, identify or authenticate articles.
