Abstract: Optical recording medium comprising a substrate which, as the light-absorbing layer, comprises at least one dye of the formula (I) or a layer containing this dye. In the formula, X is cyano or halogen, Y is hydrogen, C1- to C4-alkyl or C1- to C4-alkoxy, R and R , independently of one another, are C1- to C6-alkylcyanoethyl, C1- to C4-alkoxy-C2- or -C3-alkyl, C2 - to C4-hydroxyalkyl, C3- to C6-alkenyl or C1- to C4-alkanoyloxy-C2- or -C3-alkyl or is a saturated heterocyclic ring, R is C1- to C4-alkanoyl or optionally substituted benzoyl. The dyes (I) have an absorption maximum in the range from 600 to 660 nm. The dyes are very stable and nontoxic. The recording media can be written and read using an He-Ne laser.
