    • An authenticatable product comprising a non-opaque latent image layer of anisotropic polymer material having background optical properties with a given preferred direction of anisotropy and a given proportion of crystallinity, the latent image layer being treated so as to include: a first localized modification in the latent image layer being associated with a first latent image; and a second localized modification in the latent image layer being associated with a second latent image such that, when viewed directly, the first latent image and the second latent image are indistinguishable from the remainder of the latent image layer and, under polarized visualization, a maximum contrast between the first latent image and the remainder of the latent image layer is actualized at a different orientation of polarized visualization than a maximum contrast between the second latent image and the remainder of the latent image layer.
    • 一种可认证的产品,其包括具有给定优选的各向异性方向和给定比例的结晶度的背景光学特性的各向异性聚合物材料的非不透明潜像层,所述潜像层被处理为包括:第一局部改性 潜像层与第一潜像相关联; 并且潜像层中的第二局部修改与第二潜像相关联,使得当直接观看时,第一潜像和第二潜像与潜像层的其余部分不可区分,并且在极化可视化下, 在第一潜像和潜像层的剩余部分之间的最大对比度以与第二潜像与潜像层的其余部分之间的最大对比度不同的偏振可视化取向实现。
