有機物、例えばホトクロミンク性を有するスピロピラン
系化合物を含有する光記録体の応用が検討されている。Currently, optical recording materials mainly made of inorganic substances such as Se and Te are used, but there is a problem that the sensitivity of recording materials is low. 6 As recording speeds increase, recording materials with higher sensitivity are being used. is desired. As a method for increasing sensitivity, the application of optical recording materials containing organic substances, such as spiropyran compounds having photochromic properties, is being considered.
この種の光記録材として、例えば特願昭５６−１３０１
００に記載のものが挙げられる。As this type of optical recording material, for example, Japanese Patent Application No. 56-1301
Examples include those described in 00.
上記従来技術の１つであるＳｅ、Ｔｅなとの無機物から
成る光記録材に関しては、感度が低いために記録に長時
間を要するという問題があり。Regarding optical recording materials made of inorganic substances such as Se and Te, which is one of the above-mentioned conventional techniques, there is a problem that recording takes a long time due to low sensitivity.
方有機物から成る光記録材は、高感度ではあるが、記録
内容の再生時に、記録材が光によって劣化したり、ある
いは、記録材の熱的安定性が十分高くないために、記録
の長期保存が困難であるという問題があった。Although optical recording materials made of organic compounds have high sensitivity, they may deteriorate due to light during playback of the recorded content, or the thermal stability of the recording materials may not be high enough, making long-term storage of records difficult. The problem was that it was difficult.
本発明の目的は旨感度で、しかも再生時の光劣化がなく
、記録の保存安定性の高い光記録材およびそれを用いた
記録再生方法を提供することにある。An object of the present invention is to provide an optical recording material that is sensitive, has no optical deterioration during reproduction, and has high recording storage stability, and a recording and reproduction method using the same.
Ｌ記目的は、ニトロンを含む光記録材を支持体上に塗布
し記録層を形成し、所定の波長の光により記録層にパタ
ーン露光を行ない、記録層を酸性蒸気雰囲気下で定着さ
せ、しかる後に記録内容を再生することによって達成さ
れる。The purpose of item L is to coat an optical recording material containing nitrone on a support to form a recording layer, perform pattern exposure on the recording layer with light of a predetermined wavelength, fix the recording layer in an acidic vapor atmosphere, and then This is achieved by later reproducing the recorded content.
また酸性蒸気によって定着された記録層は、アルカリ蒸
気雰囲気下に放置することで、記録可能な状態に変換で
きるので、追加記録も可能である。Furthermore, since the recording layer fixed by acidic vapor can be converted into a recordable state by leaving it in an alkaline vapor atmosphere, additional recording is also possible.
本発明による光記録材としては感光性ニトロンもしくは
該材料と有機高分子との混合物を用いる。As the optical recording material according to the present invention, photosensitive nitrone or a mixture of this material and an organic polymer is used.
で表わされるニトロンに紫外光（３５０〜４５０ｎｍ）
を照射すると、下記光化学反応が誘起され３５０〜４５
０ｎｍにおける光吸収が消失される。Ultraviolet light (350 to 450 nm) to the nitrone represented by
When irradiated with
Light absorption at 0 nm is eliminated.
この光反応を利用して、所定パターンを光記録材に記録

波長光で再生すると記録内容が破壊されたり、あるいは
劣化するという問題がある。Using this photoreaction, a predetermined pattern is recorded on the optical recording material. In this state, if the recorded content is reproduced using the same wavelength light used for pattern recording, there is a problem that the recorded content may be destroyed or deteriorated.

化させることなく再生することが可能となる。The inventors found that when 5-nitrone is left in acidic vapor (e.g. hydrochloric acid, nitric acid, hydrofluoric acid, hydrogen bromide #) for a few seconds,
It has been found that it is possible to achieve a state in which the light absorption intensity in the ultraviolet region is fixed with almost no change (slightly shifted to the long wavelength side) 5, that is, no change in light absorption occurs even when ultraviolet light is irradiated. By utilizing this phenomenon, it becomes possible to use the same wavelength light used for pattern recording and to reproduce the recorded content without deteriorating it.
また定着された記録部材をアルカリ性蒸気（例えばアン
モニア）中に放置すると可逆的に非定着状態に再変換す
ることも可能であるので、追加記録もできる。Further, if the fixed recording member is left in alkaline vapor (for example, ammonia), it can be reversibly converted back to a non-fixed state, so that additional recording can be performed.
以下本発明の一実施例を第１図により説明する。 An embodiment of the present invention will be described below with reference to FIG.
実施例１

Ｌｏｇを８５ｇのアニソールに溶解させ、石英板上に塗

結果ニトロンを含む０．５μＩの薄膜を得た。Example 1 5 g of α (4-diethylaminophenyl)-N-phenylnitrone + styrene-allyl alcohol copolymer Log was dissolved in 85 g of anisole, coated on a quartz plate, and dried to remove the solvent anisole. . As a result, a 0.5 μI thin film containing nitrone was obtained.

ることが第１図の曲線１，２より判る。The ultraviolet (UV) absorption spectrum of this thin film is shown in curve 1 in FIG. Next, this thin film was irradiated with 405 nm light, and then left in hydrochloric acid vapor for 10 seconds.
The absorption spectrum is shown in curve 2 of FIG. 405nm
It can be seen from curves 1 and 2 in FIG. 1 that the light absorption at 405 nm disappears by irradiation with light at 405 nm.

状態とを可逆的に交換できることを示している。On the other hand, a thin film containing nitrone was separately formed on a quartz plate, and the U of the film was fixed by leaving it in hydrochloric acid vapor for 10 seconds.
The V absorption spectrum is shown in curve 3 in FIG. Even when the fixed thin film was irradiated with light of 405 nm, no UV absorption spectrum was observed. Furthermore, after leaving the fixed thin film in alkaline vapor for 10 seconds, the UV absorption spectrum was determined and the song I! shown in Figure 1 was obtained. Exactly the same absorption spectrum as 1 was obtained. This indicates that the fixed and non-fixed states can be reversibly exchanged.
実施例２
実施例１で述べた定着に用いた塩酸の代わりに硝酸、フ
ッ化水素酸を用いた場合にも塩酸と同様に定着された。Example 2 Even when nitric acid or hydrofluoric acid was used instead of the hydrochloric acid used for fixing as described in Example 1, fixing was achieved in the same way as with hydrochloric acid.

劣化を抑えることができる。Since the present invention uses nitron, which is efficiently decomposed by ultraviolet light irradiation, as an optical recording material, the information recording speed can be greatly increased. In addition, since information can be fixed after being recorded, it is possible to use light of the same wavelength as the light used for recording to reproduce the information, and it also prevents destruction of the recorded content.
Deterioration can be suppressed.
