<P>PROBLEM TO BE SOLVED: To provide an optical recording medium which can suitably perform a read-out operation and a write operation with a so-called blue laser, and is excellent in productivity and durability. <P>SOLUTION: An optical recording medium 10 is capable of absorbing a laser beam with a wavelength of 350 to 530 nm, and comprises a recording layer 2 which is formed by using, as an optical recording material, a pigment a containing a metal complex compound containing at least a pyrazine N-oxide compound represented by the general formula [I] as a diazo component. Specifically, the optical recoding medium 10 comprises a substrate 1 made of a light transmitting material, the recording layer 2 formed on the substrate 1, a disk 100 having an antireflection layer 3 laminated on the recording layer 2 and a protection layer 4 sequentially laminated thereon, the substrate 1, the recording layer 2, the antireflection layer 3 and the protection layer 4 being adhered each other with an adhesive 5 interposed therebetween. <P>COPYRIGHT: (C)2009,JPO&INPIT |
