摘要
Disclosed are liquid-crystalline and infrared-sensitive liquid-crystalline polyesters for optical data storage, processes for the preparation of the same, and an apparatus comprising an infrared-sensitive liquid-crystalline polyester. Owing to covalently bonded dye the liquid crystalline polyester is infrared sensitive and high concentrations of dye are obtainable, without having detrimental effects on the properties of the liquid-crystalline polyester. This results in a highly sensitive liquid-crystalline polyester for optical data storage. Infrared dyes which are preferably bonded in liquid-crystalline polyester are croconium, squarilium, azo, and azamethine dyes.
