    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 to 300°C, decomposition initiating temperature of 200 to 350°C, and λ 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.
