摘要： Photochromic-dichroic articles are provided, which include a substrate having a first surface, a fixed-polarized layer over the first surface of the substrate, and a photochromic-dichroic layer over the first surface of the substrate. The fixed-polarized layer optionally includes a fixed-colorant and has a first polarization axis. The photochromic-dichroic layer includes a photochromic-dichroic compound that is laterally aligned within the photochromic-dichroic layer, and which defines a second polarization axis. 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, increased optical density and/or increased kinetics when exposed to a given amount of actinic radiation.

摘要： An improved method for authenticating articles is described. A mixture of at least two photochromic compounds that have different absorption maxima in the activated state and also preferably other different properties are incorporated into a carrier composition, e.g., ink, paint, fiber or polymer used to form the authenticating display data on the article. The authenticating display data is subjected to various steps of the authenticating method that may include preferential activation of less than all of the photochromic compounds, activation of all the photochromic compounds, preferential bleaching of less than all of the photochromic compounds, and bleaching of all the photochromic compounds. Subsequent examination of the display data following the various activation and bleaching steps by verifying means enables the article to be authenticated.
