    摘要: A projection screen (10) includes a plurality of asperities (14) extending from a substrate, the asperities having faces oriented in a plurality of directions. A photosensitive material is disposed preferentially on the faces so that a differing amount of photosensitive material is present on faces oriented generally toward a projector direction (16) relative to faces oriented generally away from the projector direction (18).

    摘要: Compositions and systems for labeling substrates, such as optical disks, using leuco dye-containing coating compositions are described. The composition can comprise a color forming composition, an electromagnetic radiation absorber, and a stabilizing agent. The color forming composition can include a leuco dye, a hexaarylbiimidazole activator, and an acid-generating source. The absorber can be admixed with or in thermal contact with the color forming composition. The stabilizing agent can be configured for protecting the leuco dye upon exposure to ambient light, wherein the stabilizing agent comprises a diarylguanidine dye salt. The coating composition can be optimized for development using electromagnetic radiation having a frequency from about 760 nm and 800 nm.
