    摘要: Described is a black dichroic dye composition comprising 2 or more dyes, wherein at least one dye, generally a red dye and optionally a yellow dye, conforms to the formula A and at least one dye, usually a blue dye, conforms to the formula B Ar 1 -N=N-[Ar 2 -N=N-] q Ar 3 -N=N-Ar 4 (B) with symbols as defined in present claims. The dye composition is well suited for combination with liquid crystal material for use, inter alia, as polarizing film and/or in liquid crystal displays, showing, inter alia, high dichroic ratio and excellent compatibility with the LC material.

    摘要: Disclosed is a composition comprising a charged particle of volume 5 nm3 to 50 million nm3 preferably having an inorganic core of SiO2, AI2O3, and/or TiO2, or a core essentially consisting of an organic pigment and/or pigment derivative, and a counter ion which is separable from the particle and is not covalently linked to the particle, said counter ion comprising a silicon atom which is directly bound to a carbon atom. Preferably, said charged particle comprises a dye attached to said inorganic core and said counter ion comprises a (poly)siloxane moiety linked via suitable bridge members to a quaternary, positively charged, nitrogen or phosphorus atom, or to a moiety carrying an anionic functional group. Said composition may be used e.g. in the form of a homogenous dispersion in an electrophoretic display.

    摘要: This invention relates to an optical recording medium, comprising a substrate, a reflecting layer and a recording layer based on compounds of formula (I), (II), (III) or (IV). Attention is drawn to the description for the precise meanings of the substituents. Recording and playback are carried out especially at a wavelength of from 350 to 500 nm, for example using a blue laser. The recording and playback quality is excellent and allows high storage density. Likewise claimed are some novel compounds of formula (I), (II), (III) or (IV), as well as an optical recording medium comprising, in the following arrangement, a) a supporting material consisting of a reflecting metal or, preferably, of a polymer having a reflection metallic layer; b) an optical recording layer; c) a separating layer consisting of a metallic, crosslinked organometallic or dielectric inorganic substance; and c) a covering layer.
