Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dye, a pigment, a photoelectric functional material, and a recording / recording material, in particular, a recording dye for a large-capacity write-once optical recording medium capable of recording / reproducing information with a blue laser beam. The present invention relates to a benzobisazole-based compound useful as a compound. The present invention also relates to an optical recording medium containing the benzobisazole-based compound as a recording material, and more particularly to a write-once optical recording medium that can be recorded and reproduced with a blue laser beam.

[0002]

2. Description of the Related Art As a recordable optical recording medium conforming to the compact disk (hereinafter abbreviated as CD) standard, a CD-R is used.
(CD-Recordable) is widely used.
The recording capacity of a CD-R is about 680 MB, but with the dramatic increase in the amount of information, the demand for higher density and larger capacity of information recording media is increasing.

[0003] By shortening the wavelength of a recording and reproducing laser, a beam spot can be reduced, and high-density optical recording can be performed. Recently, the development of short-wavelength semiconductor lasers used in optical disk systems has been advanced, and
nm, 660 nm, 650 nm and 635 nm red semiconductor lasers have been put into practical use [for example, Nikkei Electronics No. 592, p. 65, 1993 10
Issue on March 11]. A DVD in which a moving image of two hours or more is digitally recorded using these semiconductor lasers has been put to practical use. Since DVD is a read-only medium, a write-once optical recording medium (DVD-R) corresponding to this capacity is also being developed.

Further, the development of semiconductor lasers in the blue region having a wavelength of 400 nm to 500 nm, which enables ultra-high-density recording, has been rapidly progressing [for example, see Nikkei Electronics No. 708, p. 117, January 26, 1998], and a write-once optical recording medium corresponding thereto has been developed.

[0005] When pits are formed by irradiating the recording layer of a write-once optical recording medium with a laser beam to cause a physical or chemical change in the recording layer, pits having good optical constants and decomposition behavior of the compound are formed. It is an important factor to make it happen. Those that are difficult to decompose have reduced sensitivity, while those that are severely decomposed or are subject to change have a greater effect between pits and in the radial direction, making reliable pit formation difficult. When recording is performed using a blue semiconductor laser wavelength, a conventional CD-R medium cannot obtain high recording characteristics because the recording layer has a low refractive index and an extinction coefficient is not an appropriate value. Therefore, it is necessary to select an appropriate compound having an optical property and a decomposition behavior for a blue semiconductor laser as a compound used for the recording layer. At present, as an example of an organic dye compound for recording a blue semiconductor laser, see JP-A-4-74.

And the like, a squarylium-based dye compound and the like are proposed.

Japanese Patent Application Laid-Open No. 11-53758 discloses two layers of a recording layer mainly composed of a porphyrin-based dye or a cyanine-based dye as an organic dye for forming a recording layer, and a metal reflection layer mainly composed of silver. The optical recording medium described above, a blue sensitive dye layer containing a cyanine dye sensitive to a blue laser, and a red sensitive dye layer or an infrared sensitive dye layer to enable recording in a two-wavelength region. 1
Various optical recording media with improved layer structures, such as the optical recording media described in JP-A-203729, have also been proposed.

As a recent situation, wavelengths of 400 to 410 n
m blue-violet semiconductor laser has been developed, and ultra-high density recording of 15 to 30 GB capacity is possible by optical recording with this laser. [For example, Nikkei Electronics No. 736, p. No. 33, February 8, 1999 issue, ibid. 741, p. 28, April 1, 1999
9th issue, No. 9 748, p. 19, July 2, 1999
No. 6, Issue No. 6 751, p. 117, September 6, 1999]. However, the above-described optical recording medium for a blue semiconductor laser is not sufficiently adapted to laser light having a wavelength of 400 to 410 nm. That is, in the medium using the above-mentioned organic dye, the signal-to-noise ratio (C / N) is not always a good value in reproducing the recorded signal, and thus the signal cannot be read out satisfactorily. We have found that Overcoming this problem, wavelength of 400-410nm
The development of an optical recording medium capable of high-density recording / reproduction with a laser beam has been urgently needed.

[0008]

SUMMARY OF THE INVENTION The present inventors have studied recording materials suitable for write-once optical recording media.
The following two findings were obtained. (1) Since a large-capacity write-once optical recording medium uses a laser beam of 350 to 500 nm for recording and reading, control of the absorption coefficient, refractive index, and reflectance near the laser wavelength is important as a recording material. is there. (2) As described above, large-capacity write-once optical recording media using the laser have been actively developed. The above-mentioned dye compound as a recording material capable of recording / reproducing with respect to a laser beam in a blue wavelength region has not yet obtained sufficient characteristics, and there is room for improvement. In addition, when producing a medium by a coating method such as a spin coating method in which a recording film is easily formed, one of the advantageous characteristics is that it has high solubility in a coating solvent. It is necessary to.

An object of the present invention is to create an optimal dye compound for recording / reproducing information by light and to provide an optical medium capable of excellent optical recording / reproduction by using the compound. Further, it is an object of the present invention to provide an optical recording medium having a recording layer suitable for ultra-high-density recording capable of performing good recording and reproduction with a blue semiconductor laser beam, particularly a laser beam selected from the wavelength range of 400 nm to 410 nm. is there.

[0010]

The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, as a dye, a pigment, a photoelectric functional material, and a recording / memory material, in particular, a blue laser beam has been used as information. A benzobisazole-based compound useful as a recording dye for a large-capacity write-once optical recording medium capable of recording and reproducing data has been found, and the present invention has been achieved. Further, by providing the benzobisazole-based compound in the recording layer, an excellent optical recording medium capable of performing good recording and reproduction with a laser beam selected from an oscillation wavelength of 400 nm to 500 nm was found, and the present invention was achieved.
