Laked tris- or tetracationic polymethine dyes

摘要

In laked tris- or tetracationic polymethine dyes <IMAGE> the variables have the following meanings: A is the radical of a substituted or unsubstituted benzene or naphthalene nucleus which is fused onto the heterocycle; Y is nitrogen or phosphorus; R comprises identical or different members of the following radicals: C1-C18-alkyl groups whose carbon chain may be interrupted by oxygen atoms in ether function and which may carry up to three of the following substituents: carboxyl, C1-C4-alkanoyl, C1-C4-alkoxycarbonyl, C1-C4-alkanoylamino, C1-C4-alkoxycarbonylamino, acryloyloxy, methacryloyloxy, phenyl, amino, cyano, hydroxyl or halogen; and phenyl or C5-C7-cycloalkyl groups which may each carry up to three of the following substituents: C1-C4-alkyl, C1-C4-alkoxy or halogen; Z is -NR<1>-; -O-; -S-; -C(CH3)2- or -CH=CH-, where R<1> is a radical as defined for R; D is <IMAGE> or <IMAGE> where X is aryloxy or arylthio each of which may carry up to five of the following substituents: amino, halogen, nitro, cyano, isocyanato, isothiocyanato, hydroxyl, carboxyl, acryloyloxy, methacryloyloxy, C1-C12-alkyl, C2-C12-alkenyl, C1-C12-alkoxy, C1-C12- alkanoyl, C1-C12-alkanoyloxy, C1-C12-alkoxycarbonyl, C1-C12-alkoxycarbonyloxy, mono-(C1-C12-alkyl)amino and/or di-(C1-C12-alkyl)amino, in which the carbon chain of the alkyl radicals may be interrupted by oxygen atoms in ether function, and the alkyl radicals...
