    摘要： Photochromic-dichroic articles are provided, which include a substrate, a first photochromic-dichroic layer over the substrate, and a second photochromic-dichroic layer over the first photochromic-dichroic layer. The first photochromic-dichroic layer includes a first photochromic-dichroic compound that is laterally aligned within the first photochromic-dichroic layer, and which defines a first polarization axis of the first photochromic-dichroic layer. The second photochromic-dichroic layer includes a second photochromic-dichroic compound that is laterally aligned within the second photochromic-dichroic layer, and which defines a second polarization axis of the second photochromic-dichroic layer. The first polarization axis and the second polarization axis are oriented relative to each other at an angle of greater than 0° and less than or equal to 90°. The photochromic-dichroic articles can provide, for example, a combination of increased optical density and increased kinetics when exposed to a given amount of actinic radiation.

Other embodiments relate to optical elements comprising a substrate and at least one at least partially aligned photochromic-dichroic compound connected to at least a portion of the substrate and having an average absorption ratio greater than 2.3 in the activated state as determined according to CELL METHOD. Still other embodiments relate to security devices, liquid crystal cells and methods of making the same.
