〈産業との利用分骨〉
本発明は、α−シアノアゾメチン系化合物、その製法及
びそれを用いた光情報記録媒体に関する。Detailed Description of the Invention <Industrial Applications> The present invention relates to an α-cyanoazomethine compound, a method for producing the same, and an optical information recording medium using the same.
〈従来の技術〉
゛ 光情報記録媒体は媒体
と書き込みないし読み出しヘッドが非接触であるので、
記録媒体が摩耗劣化しないという特徴をもち、このため
、種々の光情報記録媒体の開発研究が行われている。<Prior art> ゛ Since optical information recording media have non-contact between the medium and the writing or reading head,
The recording medium has a characteristic that it does not deteriorate due to wear and tear, and for this reason, research and development of various optical information recording media are being conducted.
このような光情報記録媒体のうち、暗室による現像処理
が不要である等の点で、ヒートモード光情報記録媒体の
開発が活発になっている。Among such optical information recording media, heat mode optical information recording media are being actively developed because they do not require development in a dark room.
このヒートモードの光記録媒体は、記録光を熱として利

ー等の記録光で媒体の一部を融解、除去等して、ピット
と称される小穴を形成して書き込みを行い、このピット
により情報を記録し、このピットを読み出し光で検出し
て読み出しを行うピット形成タイプのものがある。This heat mode optical recording medium is an optical information recording medium that uses recording light as heat. For example, a part of the medium is melted or removed using a recording light such as a laser to form a pit. There is a pit-forming type in which writing is performed by forming small holes, recording information using the pits, and reading by detecting the pits with a readout light.
したがって、光情報記録媒体は、レーザー光のエネルギ
ーを効率よく吸収する必要があるため、記録に使用する
特定の波長のレーザー光に対する吸収が大きいこと、情
報の再生を正確に行うため、再生に使用する特定の波長
のレーザー光に対する反射率が高いことが必要となる。Therefore, optical information recording media must absorb the energy of laser light efficiently, so they must have high absorption of laser light of a specific wavelength used for recording, and must be used for reproduction in order to accurately reproduce information. It is necessary that the reflectance for laser light of a specific wavelength is high.
このようなピット形成タイプの記録媒体、特にそのうち
、装置を小型化できる半導体レーザーを光源とするもの
においてはこれまで、Teを主体とする材料を記録層と
するものが大半をしめている。Up to now, most of these pit-forming type recording media, particularly those using a semiconductor laser as a light source, which can reduce the size of the device, have a recording layer made of a material mainly composed of Te.
しかし、近年、Te系材料が環境汚染の問題があること

ストを安価にする必要があること等から、Te系にかえ
有機色素を主とした有機系材料の記録層を用いる記録媒
体についての提案や報告が増加している。However, in recent years, Te-based materials have been known to cause environmental pollution problems, as well as the need for higher sensitivity and lower manufacturing costs, so organic dyes have been used instead of Te-based materials. Proposals and reports about recording media using recording layers made of organic materials are increasing.
この有機系材料に用いる色素としては、シアニン系色素
1fi(例えば特開昭58−114989号公報)、金
属錯体(例えば特開昭58−16888号公報)等が提
案されている。As dyes to be used in this organic material, cyanine dyes 1fi (eg, JP-A-58-114989), metal complexes (eg, JP-A-58-16888), and the like have been proposed.
〈発明が解決しようとする121 m >しかしながら

不安定であるため、濡々の安定化方法(例えば特開昭8
B−81792号公報)が提案されており、いまなお
改良がつづけられている。<121 m to be solved by the invention> However, since these compounds are unstable when stored in the air in a thin film state, wet stabilization methods (for example, JP-A No. 8
B-81792) has been proposed, and improvements are still being made.
本発明は、半導体レーザー光に対する吸収及び反射が大
