1241581 玖、發明說明: 【發明所屬之技術領域】 本發明是有關於一種光記錄媒體(optica丨recording medium) ’且特別是有關於一種光記錄媒體之記錄層中包含至 ’種具特別B能基的非對稱花青染料(asymmetric trimethine-cyanine dye)和一種添加物(addit丨·νβ),可增加 DVD-R 的燒錄靈敏度(wnting sensjtivity)。 【先前技術】 利用雷射光技術將資料儲存於光記錄媒體已為大眾所熟 悉。在CD-R記錄媒體的結構中,最重要的記錄層(rec〇「djng layer)為一有機染料層、再加上一反射層和一保護層,依次層 豐於一透明基板上而形成一光碟片。進行碟片上的資料燒錄 時,疋透過使用波長780 nm到830 nm的雷射光,以一定的 燒錄功率燒錄,致使記錄層上的染料產生分解或變形,造成燒 錄區域與未燒錄區域之間反射率之差異。@此,儲存於碟片上 的資料可經由使用適當功率的雷射光讀取,而觀察碟片亦可顯 現出記錄層上之記錄區與非記錄區的反射率差異。 ★已知越短波長的雷射光其光點範圍也越小。因此,許多研 九致力毛展爿b以波長介於62〇nm到690 nm的雷射光進行燒錄 及項取的光碟片,以提升記錄密度(「ecordingdensity)。「可 錄之;數位多功能影音光碟片」(DVD-R),具有高記錄密度的儲 子彳。貝取肊力的碟片’勢必成為新一代記錄媒體的主流。既鈇 進行資料儲存㈣取時,DVD_R所使賴雷射光波長範圍不= 於CD R所使用的雷射光波長範圍,所以,應用於⑶_ 錄層材料係無法適用於_七。因此,需針對dvd_r本身的 1241581 特殊性,尋找出合適的記錄層材料。 目前DVD-R的記錄層材料,化—她心㈣ 染料是常用材料之一。美國專利案,案號5 976 658和案號 6’291,045均提出’具有對稱或非對稱jnd〇|enine結構的 trimethine-based cyanine染料在[^口七上的應用。可是當 DVD-R燒錄機的雷射光波長由635nm改變為65〇门⑴(或更高) 時,對於染料的材質必須謹慎地選擇。因為當雷射光的波長變 長,在波長650 nm下薄膜狀態的染料吸收率(dye abs〇rbance) 也要稍微增加。換言之,原本適用於燒錄波長635nm的染料, 在燒錄波長變為650 nm時並不一定適用,因為燒錄靈敏度在 特定波長下,具有較低光吸收率之記錄層需要較高的燒錄功率 來寫入資訊’燒錄感度不足或過高可能導致燒錄失敗。 【發明内容】 美國專利案,案號6338888,提出:在雷射光的寫入波長 下,提升有機層染料的吸收率可增加燒錄靈敏度(recording sensitivity)。據此,本發明提出一種新組成,此組成包含一特 殊的添加物(additives),可增加燒錄靈敏度。 本發明的第一個目的,是提出一種具有拉電子基 (electron-withdrawing group,EWG)的非對稱(asymmetric) indolenine cyanine 染料,其含有一 indolenine 環或 benzoindolenine 環,如圖 1 中化學式[1],[2],[3],[4]所示。 1241581 圖1
