Abstract:
     This invention relates to a optical recording medium, comprising: a base plate, a recording layer which comprises organic dye and can record data by laser irradiation, a reflecting layer, and a protective layer. The organic dye is a phthalocyanine with a substituent group indicated as formula(I), wherein: R1,R2, R3 and R4 can represent respectively an alkyl chain with 1 to 12 carbon atoms, which can be substituted by 0-6 halogen atoms, hydroxyl groups, 1-6 carbon atoms alkoxy group, 1-6 carbon atoms alkylamino group, 1-6 carbon atoms dialkylamino group, or 1-6 carbon atoms alkylsulfur group; an alkene chain with 2-12 carbon atoms, or an alkynyl chain with 2-12 carbon atoms; M is two hydrogen atoms, a divalent metal, a trivalent metal with a single substitute, a tetravalent metal with double substitutes, or an O-metal group; S indicates a molecule group with -SO3- radicals; and n is a integer between 1 and 4.
