Abstract

本发明涉及含有优选透明的基材的光学数据载体，该基材任选已涂敷了一层或多层反射层，在其表面上施涂能够用光进行写的信息层，任选的一层或多层的反射层和任选的保护层或附加的基材或覆盖层。该光学数据载体能够利用蓝光，红光或红外光，优选激光来进行写和读，并且信息层包括吸光性化合物和任选的粘结剂。本发明的数据载体进一步的特征在于至少一种菁染料用作该吸光性化合物。

Description

在信息层中包括菁染料作为吸光性化合物的光学数据载体
本发明涉及在信息层中包括菁染料(cyaninfarbstoff)作为吸光性化合物的一次写入型光学数据载体，涉及它的生产方法和涉及由旋涂或汽相沉积将上述染料施涂于聚合物基材(尤其聚碳酸酯)上的方法。
采用特定的吸光物质或其混合物的一次写入型光学数据载体特别适合用于以蓝色激光二极管、尤其GaN或SHG激光二极管(360-460nm)操作的高密度可写光学数据储存介质(Datenspeicher)和/或用于以红色(635-660nm)或红外(780-830nm)激光二极管操作的DVD-R或CD-R盘片。
一次写入型光盘(CD-R，780nm)最近实现了巨大容量的生长并代表了技术上成熟的系统。
下一代的光学数据储存介质-DVD系列-目前已经引入到市场。由于短波激光照射(635-660nm)和较高的数值孔径NA的使用，该存储密度能够提高。在这种情况下可写格式是DVD-R。
今天，已经开发出了使用高激光功率的蓝色激光二极管(基于GaN，JP08 191171或二次谐波发生SHG，JP09 050 629)(360nm-460nm)的光数据存储格式。可写光学数据储存介质因此也用于这一代。能实现的存储密度取决于激光焦点在该信息面上的聚焦。焦点尺寸用激光波长λ/NA定标。NA所使用的物镜的数值孔径。为了获得最高可能的存储密度，最小可能的波长λ的使用是目标。目前，基于半导体激光二极管，390nm是可能的。
该专利文献描述了染料型可写光学数据储存介质，它们同样地适合于CD-R和DVD-R系统(JP-A 11 043 481和JP-A 10 181 206)。为了实现高反射率和读出信号的高调制高度和实现足够的写入敏感性，可利用以下事实：CD-R的780nm的IR波长位于染料的吸收峰的长波长侧翼(Flanke)的根部和DVD-R的635nm或650nm的红色波长位于染料的吸收峰的短波长侧翼的根部。在JP-A 02 557 335，JP-A 10058 828，JP-A 06336086，丁P-A 02 865 955，WO-A 09 917284和US-A 5 266699中，这一概念延伸到在吸收峰的短波长侧翼上的450nm工作波长区域和在长波长侧翼上的红色和IR区域。
除该上述的光学性质外，得自吸光性有机物质的可写信息层需要具有尽可能无定形的形态，以便在写或读过程中保持尽可能小的噪音信号。因此之故，特别优选的是，在随后的减压下的金属或电介质层覆盖中，在通过从溶液旋涂、通过汽相淀积(Aufdampfen)和/或升华来施涂吸光物质的操作防止该吸光物质的结晶。
得自吸光物质的无定形层优选具有高度耐热变形性，因为通过喷溅或汽相淀积被施涂于吸光性信息层中的有机或无机材料的其它附加层将由于散射而形成变模糊的边界，因此不利地影响反射率。此外，具有不够的耐热变形性的吸光物质能够在聚合物载体的界面，扩散到该载体中，和再次不利地影响该反射率。
蒸汽压力太高的吸光性物质能够在利用高真空下的上述喷溅或汽相淀积附加层的过程中发生升华和因此将层厚度降低到低于所需要的值。这进而不利地影响该反射率。
因此本发明的目的是提供满足可用于在一次写入型光学数据载体中的信息层中，尤其用于在340-830nm的激光波长范围内的高密度可写光学数据存储格式的高要求(例如光稳定性，有益的信号/噪声比，对基材的无损害式施涂，等)的合适的化合物。
令人吃惊地已经发现，选自菁染料类的吸光性化合物能够特别充分地满足上述要求范围(profil)。
因此本发明涉及包括优选透明的基材的光学数据载体，任选地该基材已涂敷了一个或多个反射涂层和在该基材的表面上已经涂敷了光可写型信息层、任选的一个或多个反射涂层和任选的保护层或附加基材或覆盖层，其能够利用蓝色、红色或红外光(优选激光)进行写和读，其中信息层包括吸光性化合物和任选的粘结剂，特征在于至少一种菁染料用作吸光性化合物。
吸光性化合物应该优选能够以加热途径来改变。热改变(thermische Vernderung)优选在＜600℃的温度下，特别优选在＜400℃的温度下，非常特别优选在＜300℃的温度下，尤其＜200℃下发生。该变化能够是，例如，吸光性化合物的发色中心的分解或化学变化。
优选的是通式(I)的菁染料

该菁染料优选通过旋涂方法或真空汽相淀积方法被施涂于光学数据载体上。该菁染料能够彼此混合或与其它具有类似物光谱性质的染料混合。尤其，含有不同的阴离子的染料也可以混合。信息层能够不仅包括菁染料，而且包括诸如粘结剂，润湿剂，稳定剂，稀释剂和增感剂以及其它成分之类的添加剂。

除信息层外，其它的层如金属层，电介质层，阻隔层和保护层可以存在于该光学数据载体中。金属和电介质和/或阻隔层尤其用于调节反射率和热吸收/保留(Wrmehaushalts)。取决于激光波长，金属能够是金，银，铝等等。电介质层的例子是二氧化硅和氮化硅。阻隔层是电介质层或金属层。保护层是例如可光致固化的涂层，(压敏)粘合层和保扩膜。
