TAMPER INDICATING ARTICLE

摘要

Tamper indicating articles that include a surface-feature image-generating layer and an adhesive layer are described. The surface-feature image-generating layer generates a visible, surface-feature-generated image upon exposure to light. The intensity of the surface-feature-generated image is reduced when taped-over. Single-image and dual- image tamper indicating articles are also described, including buried dual-image and adjacent dual-image tamper indicating articles.
