    • A visible light transmissive card includes a security indicia that fluoresces under UV light. The card also includes at least one IR filter. The IR filter and/or another card layer that is substantially coextensive with a front card surface includes a component that also fluoresces under UV light. A UV blocking material is disposed between the security indicia and the UV-excitable component of the IR filter or other layer, so that the security indicia is clearly visible when the card is exposed to UV light. In some embodiments the UV blocking material is patterned to define (in combination with the fluorescing IR filter or another coextensive card layer) a secondary security indicia, which may be used in addition to or in place of the original security indicia. IR filter laminates used in the construction of such cards are also disclosed.
    • 可见光透射卡包括在UV光下发荧光的安全标记。 该卡还包括至少一个IR滤波器。 与前卡表面基本上共同延伸的IR滤光片和/或另一卡层包括在UV光下也发荧光的成分。 紫外线阻挡材料设置在IR滤光器或其他层的安全标记和UV可激发部件之间,使得当卡暴露于UV光时,安全标记清晰可见。 在一些实施例中,UV阻挡材料被图案化以限定(与荧光IR滤光器或另一共同扩展卡层组合)第二安全标记,其可以在原始安全标记之外或代替原始安全标记使用。 还公开了用于这种卡的结构中使用的IR滤光层压板。
