    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： Carbonyloxy-substituted azulenesquaric acid dyes of the formula ##STR1## where L is C.sub.1 -C.sub.12 -alkylene which may be substituted by phenyl,R.sup.1 is C.sub.1 -C.sub.12 -alkyl, monounsaturated or polyunsaturated C.sub.3 -C.sub.12 -alkenyl, which may be phenyl-substituted, C.sub.3 -C.sub.7 -cycloalkyl, C.sub.3 -C.sub.7 -cycloalkenyl, substituted or unsubstituted phenyl, pyrrolyl, furanyl, thienyl or pyridyl and R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are each independently of the others hydrogen or substituted or unsubstituted C.sub.1 -C.sub.12 -alkyl, with the proviso that when R.sup.3 is hydrogen the positions of the substituents CH.sub.2 --L--O--CO--R.sup.1 and R.sup.4 on either or both azulene rings may also be interchanged with each other within an azulene ring, are useful in an optical recording medium.
