  • Detector for identifying at least one material property
    Patent number: 11947013
    Abstract: Described herein is a detector for identifying at least one material property m. The detector includes at least one sensor element including a matrix of optical sensors, the optical sensors each having a light-sensitive area. The sensor element is configured for recording at least one reflection image of a light beam originating from at least one object. The detector includes at least one evaluation device configured for determining the material property by evaluation of at least one beam profile of the reflection image.

  • Method for producing alkoxy-substituted phthalocyanins
    Publication number: 20070179285
    Abstract: The invention relates to a process for preparing alkoxy-substituted, metal-containing phthalocyanines of the formula (I) where R is substituted or unsubstituted alkyl or cycloalkyl, M is a divalent metal atom, metaloxy or a trivalent or tetravalent substituted metal atom, characterized in that the phthalonitrile of the formula (II) is reacted in the presence of a metal salt and a base in a water-miscible solvent.

  • Optical data store comprising a cobalt phthalocyanine with an axial substituent and axial ligand in an information photoinscribtible layer
    Publication number: 20060292326
    Abstract: Optical data carriers whose information layer comprises at least one light-absorbent compound which is a Co(III) phthalocyanine in which the Co metal centre bears an axial substituent R1 and an axial coordinated ligand R2, where R1 is CN, SCN, halogen, in particular Cl, Br or F, alkoxy, aryloxy, arylthio or alkylthio and R2 is no ligand or substituted or unsubstituted amine, water, an alcohol, H2S, a thioalcohol or an isonitrile.

  • Azo metal dyes and optical data carrier containing one such azo metal dye as a light absorbing compound in the information layer
    Publication number: 20060235210
    Abstract: Optical data carrier comprising a preferably transparent substrate which may, if desired, have previously been coated with one or more reflection layers and to whose surface a light-writeable information layer, if desired one or more reflection layers and if desired a protective layer or a further substrate or a covering layer have been applied, which can be written on and read by means of blue, red or infrared light, preferably laser light, where the information layer comprises a light-absorbent compound and, if desired, a binder, characterized in that at least one azo metal dye is used as light-absorbent compound.
