SOLUTION: This optical recording medium has a recording layer substantially comprising at least one dye represented by formula I (wherein R1 and R2 are each a 1-8C alkyl or a 2-8C alkenyl; R3 , R6 , R9 , and R12 are each H, a halogen, CN, etc.; R4 , R5 , R7 , R8 , R10 , and R11 are each H, a halogen NO2 , CHO, etc.; and M is H2 , a divalent metal atom, an oxometal, a halogenometal, a hydroxymetal, etc.), or its chlorination or bromination product. This oxoporphyrin dye has a refractive index of 1.8 or higher in the range of 400-500nm. A substrate used is pref. transparent and has a thickness of 0.01-10mm. The recording layer is sandwiched between the substrates and a reflecting layer and has a thickness of 10-100nm. The absorbance of the recording layer is 0.1-1.0 at the absorption max. The thickness of the reflecting layer is 10-150nm. The reflectance of the optical recording medium as a whole is 60% or higher.

Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium of which the recording layer has a large recording capacity and has other excellent characteristics in combina tion as well. SOLUTION: This recording medium includes a substrate, a reflection layer and the recording layer. The recording layer substantially consists of the dye expressed by the formula. In the formula, Y is an anion of inorg. or org. metal acid or their mixture; Z is a proton metal cation, ammonium cation or phosphonium cation or their mixture; m, n are 1 to 3 independently from each other; p and q are 0 to 4; the stoichiometric numerical values of o, p and q are so determined that the excess positive charges or negative charges do not exist at all in the formula. The substituents described above are, if desired, so connected to each other that a 5-membered or 6-membered ring is formed by direct coupling or via a bridge -O- or -NR12 -. This novel recording medium is a high-sensitivity recording medium and has good reproduction characteristics.
