An optically variable magnetic stripe assembly includes a magnetic layer, an optically variable effect generating layer over the magnetic layer, and an electrically non-conductive reflective layer between the magnetic layer and the optically variable effect generating layer.

Optically variable magnetic stripe assembly

An optically variable magnetic stripe assembly includes a magnetic layer, an optically variable effect generating layer over the magnetic layer, and a reflective layer between the magnetic layer and the optically variable effect generating layer. The reflective layer includes at least one metal portion.

A latent image structure of a highly secure nature in which two latent image are superimposed. Each of the superimposed latent images is viewable from a different line of sight. Relief elements define, for each latent image, portions of respective linear relief structures providing an image and a background which cooperate to generate the latent image. Relief elements are only provided at locations where the linear relief structures of the first and second latent images intersect. The resultant latent image structure, when viewed normally, has the advantage of a relatively flat appearance, making it difficult to discern the presence either of the superimposed latent images.
