Compact disk-write once type optical recording media |
| 摘要 |
The invention discloses a CD-WO type optical recording medium which has a constitution obtained by successively laminating a recording layer, a metal reflection layer and a protective layer; is prepared by using in the recording layer a colorant having a melting point of 150 DEG to 300 DEG C., decomposition initiating temperature of 200 DEG to 350 DEG C., and lambda max of 720 nm; and has high sensitivity, low recording distortion and high durability. The colorant can be enhanced its effect by introducing halogen atoms.
