摘要： A phthalocyanine dye of specific structure represented by the following general formula (1) or (2): ##STR1## where Y is O or S attached to the phthalocyanine ring, Z is the group of atoms required to complete a carbon or heterocyclic ring together with C, A.sub.1 is a monovalent substituent bulkier than a hydrogen atom, and each of X.sub.1 and X.sub.2 is H or a monovalent substituent or, in the alternative, X.sub.1 and X.sub.2, taken together, form a single bond, ##STR2## where Y and Z.sub.1 have the same meanings as defined for Y and Z in formula (1). A.sub.11 is a monovalent substituent having a branched alkyl group, which is attached to the ring completed by Z.sub.1, and s1 is the number of A.sub.11, is used for the recording layer of an optical recording layer. This phthalocyanine dye is unlikely to attack a substrate material such as PC, can be handled with ease, and has a high solubility in a coating solvent advantageous for film formation, for instance, an alcoholic solvent, e.g., ethyl cellosolve or an aliphatic hydrocarbon solvent.

摘要： A recording layer contains a dye A having a complex index of refraction at 780 nm whose real part n is 1.8-2.8 and imaginary part k is up to 0.15 and forming a thin film exhibiting an absorption spectrum whose half-value width is up to 170 nm and a dye B having a complex index of refraction at 630 nm or 650 nm whose real part n is 1.8-2.8 and imaginary part k is up to 0.2. An optical recording medium capable of writing and reading in a conventional wavelength region of about 780 nm and a shorter wavelength region of about 630 to 680 nm is obtained.
