CA 2337480

There was found a metallocenyl-phthalocyanine or its metal complex of a divalent metal, oxometal, halogenometal or hydroxymetal, in which at least one of the four phenyl rings of the phthalocyanine contains, bound via a bridge unit E, at least one metallocene radical as substituent, E being composed of a chain of at least two atoms or atom groups selected from the group consisting of -CH2-, -C(=O)-, -CH(C1-C4alkyl)-, -C(C1-C4alkyl)2-, -NH-, -S-, -O- and - CH=CH-, as well as mixtures of the novel compounds which comprise, inter alia, isomers, a process for the production, the use and recording media comprising the novel compounds.

L'invention concerne des métallocényl-phtalocyanines ou leur complexe métallique d'un métal divalent, d'un oxométal d'un halogénométal ou hydroxymétal, dans lequel au moins un des quatre noyaux phényle de phtalocyanine contient, relié par l'intermédiaire d'un pont E, au moins un radical de métallocène en tant que substituant, E étant constitué par une chaîne d'au moins deux atomes ou groupes d'atomes sélectionnés dans le groupe constitué par -H¿2?-, -C(=O)-, -CH(alkyle C¿1?-C¿4?)-, -C(alkyle C¿1?-C¿4?)¿2?-, -NH-, -S-, -O- et -H=CH-, ainsi que des mélanges de ces nouveaux composés comprenant, entre autres, des isomères, leur procédé de préparation, leur mise en application et des supports d'enregistrement constitués par ces nouveaux composés.
