Abstract

本发明涉及一种光数据载体，其包括优选透明的、如果需要已经被一层或多层反射层涂覆的基底。在所述基底的表面上涂有用光可记录的信息层，和如果需要一层或多层反射层和如果需要保护层或者另一基底或者覆盖层。所述光学数据载体可以用蓝光，优选激光记录和读取。所述的信息层包括吸收光的化合物和如果需要粘结剂。本发明的光学数据载体的特征在于使用至少一种酞菁染料作为吸收光的化合物。

Description

在信息层中包含酞菁染料作为吸光化合物的光数据载体
技术背景
本发明涉及一次性可记录光数据载体，该载体在信息层中包括至少一种酞菁染料作为吸收光的化合物。
一次性可记录光数据载体在使用特定的光吸收物质或其混合物下特别适合于在高密度可记录光数据存储器中使用，该存储器通过蓝激光二极管，特别是GaN或SHG激光二极管(360至460纳米)工作，和/或适合于在DVD-R和CD-R盘中使用，该盘通过红(635纳米至660纳米)和红外线(780至830纳米)激光二极管工作，以及上述染料通过旋涂、蒸镀或溅射涂覆在聚合物基底上，特别是聚碳酸酯上。
近来，该一次性可记录压缩光盘(CD-R，780纳米)的数量急剧增长，并且其是技术上成形的体系。
不久前，在市场上出现了最新一代的光数据存储器-DVD。通过使用短波激光照射(635至660纳米)和较高数值孔径NA可以提高该存储器的密度。在这种情况下，该一次性可记录格式是DVD-R。
现在，已经开发出利用具有高激光功率的蓝激光二极管(基础GaN，JP-A-08 191 171或者 Second Harmonic  Generation SHG JP-A-09050 629)(360至460纳米)的光数据存储器格式。因此，在这一代中同样也可以使用可记录光数据存储器。可获得的存储器密度取决于在信息平面中激光点的聚焦。这里，该点的大小通过激光波长λ/NA来衡量。NA是所使用物镜透镜的数值孔径。为了获得尽可能高的存储器密度，力求使用尽可能小的波长λ。现在，在半导体激光二极管的基础上，390纳米是可能的。
在专利文献中描述了基于染料的同样适合于CD-R和DVD-R体系的可记录光数据存储器(JP-A11 043 481和JP-A10 181 206)。这里，对于高的反射性和高的读取信号的调制高度以及在记录事件时足够的敏感性使用位于染料的吸收峰值的长波缘的下部的CD-R的IR波长780纳米，位于染料的吸收峰值的短波缘的下部的DVD-R的红色波长635纳米或650纳米(参见EP-A519 395和WO-A00/09522)。在JP-A02 557 335、JP-A10 058 828、JP-A06 336 086、JP-A02865 955、WO-A09 917 284和US-A5 266 699中这种概念被延伸至在吸收峰值的短波缘上450纳米的工作波长和长波缘上红色和IR的范围。
除上述光性能外，由吸收光的有机基底形成的可记录信息层具有尽可能无定形的形态，以便在记录或读取时保持尽可能小的噪声信号。对此特别优选地是，在真空中，在随后用金属或介电层覆盖时，在通过旋涂涂覆由溶液形成的物质、通过溅射或通过蒸镀和/或升华涂覆物质时防止吸收光物质的结晶。
由吸收光的物质形成的无定形层优选应该具有高的热稳定性，因为否则由有机或无机材料形成的其它层(通过溅射或蒸镀涂覆在该吸收光的信息层上)通过扩散形成模糊的界面，并因此对反射性产生不利的影响。此外，界面上的具有太低热稳定性的吸收光的物质扩散到其中的聚合物载体中并再次对反射性产生不利影响。
在上述溅射或蒸镀时，在高真空中，具有过高蒸汽压的吸收光的物质可以升华成另外的层，并因此降低所需的涂层厚度。这再次导致对反射性的不利影响。
因此本发明的任务是提供适合的化合物，其满足在360至460纳米的激光波长范围中，在特别是用于高密度可记录光数据存储器格式的一次性可记录光数据载体中的信息层中使用时的高要求(如光稳定性、有利的信噪比、在基底材料上无害的涂层等)。
令人惊奇地发现，选自酞菁类的吸收光的化合物可以特别好地满足上述各种要求。酞菁在对激光来说重要的波长范围360至460纳米中(所谓的B-或Soret-波段)具有强的吸收性。
因此，本发明涉及光数据载体，其包括优选透明的、如果需要已经被一层或多层反射层涂覆的基底，在其表面上涂有用光可记录的信息层，如果需要一层或多层反射层和如果需要保护层或者另外的基底或者覆盖层，其可以用蓝光，优选激光，特别优选360至460纳米的光，更优选380至420纳米的光，最优选390至410纳米的光记录和读取，其中所述的信息层包括吸收光的化合物和如果需要粘结剂，其特征在于，使用至少一种酞菁作为吸收光的化合物。
