Abstract
Thermally-imageable articles which allow verification of the genuineness of the articles, and methods of producing such articles are disclosed. The thermally-imageable articles includes a substrate and a light transmissive/reflective platy pigment in or on one or both surfaces of the article. The article may be analyzed or inspected to determine the presence and nature of the platy pigment and accordingly, the authenticity of the article. When viewed from different incident angles, the pigment produces a unique pearlescent, color shift, or iridescent type effect.
