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.degree. to 300.degree. C., decomposition initiating temperature of 200.degree. to 350.degree. 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.

摘要:
Near-infrared absorbers which contain phthalocyanine derivatives in which the four benzene rings contained in the molecule independently have 1 to 4 substituents are light and thermal resistant and possess high molar extinction coefficients. Such near-infrared absorbers are useful in optical recording media, near-infrared absorption filters, and liquid crystal display devices.
