Description
本發明係關於一種主要用於光學記錄材料等中之新穎之吲哚鎓化合物及含有該吲哚鎓化合物而成之光學記錄材料,詳細而言係關於一種藉由利用雷射等產生之資訊圖案賦予資訊而進行記錄的光學記錄媒體中所使用之光學記錄材料,更詳細而言係關於一種可利用具有紫外及可視區域之波長且能量較低之雷射等進行高密度之光學記錄及再生的光學記錄媒體中所使用之光學記錄材料。
光學記錄媒體通常具有記錄容量大且以非接觸方式進行記錄或再生等優異之特徵,因此廣泛普及。於WORM、CD-R、DVD±R等單寫多讀型光碟中,使雷射聚光至記錄層之微小面積上,改變光學記錄層之性狀而進行記錄,利用記錄部分與未記錄部分之反射光量之差異進行再生。
於550 nm~620 nm之範圍內具有強度較大之吸收之化合物、尤其是在550~620 nm內具有最大吸收(λmax)之化合物,被用作形成DVD-R等光學記錄媒體之光學記錄層之光學記錄材料。
作為上述光學記錄材料,含有吲哚環之吲哚鎓化合物具有靈敏度較高,可應對記錄之高速化等優點,因此提出有很多報告例。例如,專利文獻1~6中報告有苯乙烯基吲哚鎓化合物。又,專利文獻7中報告有於吲哚環之3位導入有苄基之低溫分解性之花青素化合物。業者認為低溫下分解之化合物,易於形成光學記錄層之記錄部分(訊坑),適合用於高速記錄媒體中。
然而,該等材料於耐光性或記錄特性之方面,未能獲得令人滿意之性能。
專利文獻1:日本專利特開平11-34489號公報專利文獻2:日本專利特開平11-170695號公報專利文獻3:日本專利特開2001-342366號公報專利文獻4:日本專利特開2002-206061號公報專利文獻5:日本專利特開2003-313447號公報專利文獻6:日本專利特開2003-321450號公報專利文獻7:日本專利特開2003-231359號公報
因此,本發明之目的在於提供一種耐光性較高且表現出適合高速之光學記錄用途之熱解行為的新穎之吲哚鎓化合物及含有該吲哚鎓化合物而成之光學記錄材料。
本發明者等人經反覆研究,結果發現具有特定之陽離子結構之新穎之吲哚鎓化合物作為光學記錄材料表現出良好之熱解行為,從而完成本發明。
本發明係藉由提供一種以下述通式(I)所表示之吲哚鎓化合物,而達成上述目的者。
