    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.
