介绍了染料在信息记录与存储领域的应用,如数码喷墨打印、感光材料、静电复印和光盘存储等。喷墨打印中越来越重视染料对打印材料的亲和力,活性染料在此有独特的作用。染料是光盘记录介质的主要成分,可写型光盘用染料类型是近红外吸收染料,可写可擦型光盘用染料类型是二芳基乙烯型、俘精酸酐类、螺噁嗪类等。 The application of dyes in the field of information recording and storage is introduced, such as digital inkjet printing, photosensitive materials, xerography and optical disk storage. Inkjet printing more and more attention to the dye affinity of the printing material, reactive dyes have a unique role in this. Dye is the main component of the optical disc recording medium. The dye type of the writable optical disc is near-infrared absorbing dye. The dye type of writable wipe type optical disc is diarylethene type, fulgides, spirooxazine and the like.
