    摘要： Naphtholactamsquaric acid dyes of the formula ##STR1## where R.sup.1 and R.sup.2 independently of one another are each unsubstituted or substituted C.sub.3 -C.sub.22 -alkyl, in which the alkyl chain may be interrupted by oxygen atoms, or are each unsubstituted or substituted C.sub.1 -C.sub.4 -aralkyl, unsubstituted or substituted C.sub.5 -C.sub.7 -cycloalkyl or unsubsituted or substituted phenyl, and the rings A, B, C and D are unsubstituted or substituted and/or benzofused, and optical recording materials consisting of a base and a layer which is sensitive to laser light and is composed of a thermoplastic or crosslinked polymer and one or more dyes (I).Because of the high light absorption of (I), the recording materials are very sensitive to light from the GaAlAs semiconductor laser. An excellent signal-to-noise ratio is obtained on reading the recordings.

    摘要： An optical recording medium composed of a base material and a laser light sensitive layer which contains an azulenium dye as storage material with or without a binder is obtainable by spin-coating a solution containing an azulenium dye of the formula ##STR1## where R is C.sub.1 -C.sub.6 -alkyl which may be substituted or unsubstituted, and n is 1, 2 or 3, with or without a binder and one or more solvents which have evaporation numbers of not less than 4 and in which an azulenium dye of the abovementioned formula has a solubility of not less than 5 g/l onto a transparent base material based on a plastics material or glass.
