Abstract
The optic recordable medium is sequently composed of the base plate, recordable layer containing the organic dye and capable of recoding data as illuminated by laser, the reflex layer and the protecting layer. The organic dye is the phthalocyanine with substituted group as represented by formula (I) where R1, R2, R3 and R4 respectively represent for the alkyl chain with one to twelve carbon atom, which can be substituted by 0~6 halogen atom, the hydroxyl group, the alkoxyl group with 1~6 carbon atoms, the alkyl amine group with 1~6 carbon atoms, the di-alkyl amine group with 1~6 carbon atoms, or alkyl sulfur group with 1~6 carbon atoms; M represents for the two hydrogen atoms, one divalent metal, one single substituted trivalent metal, one double substituted tetravalent metal or oxidized metal group; S represented the moiety of the sulfuric ion and n represented the integer from one to four.
