Provided is an information recording medium, e.g., an optical recording medium, and a method for recording information thereon. The information layer of the recording medium comprises an organo macrocyclic chromophore containing a central hetero atom or two central hydrogen atoms or isotopes of hydrogen, e.g., a naphthalocyanine having silicon as the hetero atom, which chromophore is substituted with at least one substituent conferring film forming properties to the chromophore, e.g., a monomer or oligomeric substituent comprised of acid, amide or ester units. The information layer thereby offers excellent thermomechanical properties and exhibits excellent absorption properties all in a single component material. By utilizing a single component material, the problem of dye/polymer phase separation frequently encountered in dye/polymer mixtures is also overcome.
提供了一种信息记录介质,例如光学记录介质,以及在其上记录信息的方法。记录介质的信息层包括含有中心杂原子或两个中心氢原子或氢同位素的有机大环色团,例如具有硅作为杂原子的萘酞菁,该色团被至少一个赋予薄膜形成特性的取代基所取代,例如由酸、酰胺或酯单元组成的单体或寡聚物取代基。因此,信息层提供了优异的热机械性能,并展现了单一组分材料中优异的吸收特性。通过利用单一组分材料,也克服了在染料/聚合物混合物中经常遇到的染料/聚合物相分离问题。
