Title (EN) AMINIUM COMPOUNDS AND OPTICAL RECORDING MEDIA CONTAINING THE SAME
(FR) COMPOSES D'AMINIUM ET SUPPORTS D'ENREGISTREMENT OPTIQUE RENFERMANT CES COMPOSES
Abstract:
(EN) New aminium compounds having an excellent solubility in solvents, being highly safe in handling and for the environment, and represented by general formula (1), (wherein R1 is a substituted or unsubstituted alkyl group; and A2 is a divalent organic anion) , and optical recording media containing the same. These compounds have a high solubility in organic solvents particularly when they are used together with dyes, and solutions thereof have a high storability. They are thus useful for producing optical recording media having a high light resistance.
(FR) L'invention concerne de nouveaux composés d'aminium présentant une excellente solubilité dans les solvants, ne présentant également aucun danger dans leur manipulation et pour l'environnement, et représentés par la formule générale (I), (dans laquelle R1 représente un groupe alkyle substitué ou non substitué, et A2 un anion organique divalent). L'invention porte également sur les supports d'enregistrement optique renfermant ces composés. Les composés de l'invention sont extrêmement solubles dans des solvants organiques, notamment lorsqu'ils sont utilisés avec des colorants, les solutions obtenues présentant une grande aptitude au stockage. Ces composés sont par conséquent utilisés pour produire des supports d'enregistrement optique présentant une haute résistance à la lumière.
