    Abstract: Dyes are transferred from a carrier by sublimation/vaporization to plastic-coated papers by a process in which the dyes used are of the general formula (I) (I) where A is D-N=N- or R1 and R2 are each hydrogen, alkyl, alkoxy, alkylthio or halogen and R1 and R together may furthermore form a 5-membered or 6-membered heterocyclic ring, and R and R' independently of one another are each hydrogen, phenyl which is unsubstituted or substituted by methyl or methoxy, or C5- or C6-cycloalkyl or C1-C6-alkyl which is unsubstituted or substituted by C1-C4-alkoxy, C1-C4-alkoxycarbonyl, C2-C5-alkanoyloxy, C1-C4-alkoxycarbonyloxy, C1-C4-alkoxy-C2-or C3-alkoxycarbonyloxy, hydroxyl, cyano, halogen, phenyl or C5- or C6-cycloalkyl, or is a 5-membered or 6-membered saturated heterocyclic ring where D is a radical of a diazo component of the thiophene, thiazole, isothiazole or 1,2,4-thiadiazole series and R3 is hydrogen or CN. In the process, the dyes (I) give strong dyeings which have good light fastness and are resistant to chemical substances.

    Abstract: The medium contains a carrier layer onto which a light-absorbing layer is applied which either consists of a dye of the formula or which contains this dye. In the formula, at least one X is and the other X are hydrogen, -OR , -SR and/or -NO2, A is alkyl which may be substituted, phenyl, benzyl or phenylethyl, or a group in 2, 3, position, n is 0, 1, 2, 3 or 4, the number of -NO2 groups being 2, R , R and R are hydrogen, alkyl, alkoxyalkyl, cyclohexyl, phenyl or phenylalkyl, the phenyl radicals possibly being further substituted, or are a saturated 5- or 6-membered heterocyclic ring and R is alkyl, alkoxyalkyl or C2/C3-alkylcarboalkoxy. The dyes have an absorption maximum in the range from 600 to 660 nm. The recording medium can be written and read with He-Ne lasers.

    Abstract: In laked tris- or tetracationic polymethine dyes 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 -; -O-; -S-; -C(CH3)2- or -CH=CH-, where R is a radical as defined for R; D is or 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...
