Abstract: Indolicin trimethine dyes of general formula (I) in which the meanings of the variables are: R represents C1-C22 alkyl groups which may carry the following substituents: halogen, hydroxy, C1-C6 alkoxy, benzyloxy, C1-C6 alkanoyl, C1-C6 alkoxycarbonyl or phenyl; C3-C7 cycloalkyl groups which may carry the following substituents: halogen, C1-C4 alkyl or C1-C4 alkoxy; phenyl groups which may carry the following substituents: halogen, hydroxy, cyano, C1-C6 alkyl, C1-C6 alkoxy, carboxy, C1-C6 alkoxycarbonyl or hydroxysulphonyl; R represents one of the radicals R , where the C chain of the C1-C22 alkyl groups may be interrupted into ether function by one to five oxygen atoms; R represents hydrogen, halogen or C1-C6 alkyl; Z represents -O- or -NH-; AN represents the equivalent of an acid anion; and optical recording media for the recording and reproduction of information by means of laser beams having an indolicin trimethine dye I in the light-sensitive layer.

Abstract: Quinoxalinepentamethine dyes of the formula where R1 is hydrogen, substituted or unsubstituted C1-C22-alkyl or substituted or unsubstituted C5-C7-cycloalkyl, R2 is hydrogen, chlorine, bromine or C1-C6-alkyl, Y is a radical of the formula -N=C(CH3)- or -N(R1)-CO-, where R1 is as defined above, Z1 and Z2 are each hydrogen or together are unsubstituted or substituted C2-C3-alkylene, X(-) is an anion and the rings A and B independently of each other may be substituted and/or benzofused and are useful in optical recording media.
