    Abstract: An optical recording material for binary, multibit or volume data storage is described. The optical recording material comprises: (a) at least one dyestuff selected from polymeric azo dyestuffs and oligomeric azo dyestuffs, the dyestuff changing its spatial arrangement upon irradiation with polarized electromagnetic radiation; and (b) optionally at least one grouping having form anisotropy. The optical recording material has the following characteristics: (i) the absorption maximum of the dyestuff(s) is at least 30 nm less than 400 nm and/or at least 30 nm greater than 400 nm; (ii) at 400 nm the dyestuff reaches an optical density of not more than 60% of its absorption maximum; (iii) the optical recording material has the capacity for being rewritten on by changing the state of polarization of actinic light, an intensity of at least 80% of the original value being achieved after a deletion/rewriting cycle; and (iv) at 400 nm, under identical conditions, an optical writing operation performed upon the optical recording material proceeds no more slowly than at 500 nm, and birefringence values induced during the optical writing operation do not differ from those birefringence values induced at 500 nm by more than 10%.

    Abstract: The present invention relates to a device for generating light signals, in particular traffic lights. The device according to the invention contains a housing with at least one opening, which is closed by a plate, the absorption of which can be controlled electrically, there being located in the interior of the housing behind the opening a diffuser element, which reflects incident light through the plate. Preferred switched states of the plate are either black (absorption over the entire spectral region of visible light) and colored transparent (slight absorption in specific spectral regions) or transparent (no absorption over the entire spectral region of visible light). The device according to the invention is used to generate light signals by virtue of the fact that the ambient light strikes the plate and, depending on switched state, is absorbed entirely, partially or not at all by the plate. The light fraction transmitted through the plate is reflected by the diffuser plate located behind the plate and transmitted a second time through the plate, and can then be perceived from outside.
