  The invention relates to a liquid crystal mixed-composition comprising one or more cellulose derivatives and one or more liquid crystal compounds (preferably low-molecular liquid crystal compound) which can be oriented in a specific direction differing from that of the cellulose derivative, wherein the ratio by weight of the both is preferably in a range from 1 : 9 to 9: 1, a retardation film produced using the composition, a circularly or elliptically polarizing film using the retardation film and an image display device provided with a circularly or elliptically polarizing film. The liquid crystal mixed-composition can be easily oriented in a specific direction on a rubbed substrate. If this orientation is fixed, a retardation film can be easily obtained which has such wavelength dispersion characteristics that the same level of retardation can be imparted to each wavelength in a wide visible region.

  本发明涉及一种液晶混合组合物，该组合物由一种或多种纤维素衍生物和一种或多种液晶化合物（最好是低分子液晶化合物）组成，可按不同于纤维素衍生物的特定方向定向，其中二者的重量比最好在 1 : 9 至 9 : 1 之间；还涉及一种使用该组合物生产的延缓膜、一种使用该延缓膜生产的圆偏振膜或椭圆偏振膜以及一种带有圆偏振膜或椭圆偏振膜的图像显示装置。液晶混合组合物可以很容易地在摩擦基板上按特定方向定向。如果固定这个方向，就可以很容易地获得一种具有波长色散特性的延缓膜，这种特性可以在很宽的可见光区域内对每个波长赋予相同程度的延缓。

• OPTICAL RECORDING MEDIUM AND METHOD OF RECORDING VISIBLE INFORMATION
  申请人：Seto Nobuo

  公开号：US20090207712A1

  公开（公告）日：2009-08-20

  The present invention relates to an optical recording medium comprising a visible information recording layer comprising a dye denoted by the following general formula (I) on a support. In general formula (I), A denotes a substituted or unsubstituted heterocyclic group, substituted aliphatic group, or substituted or unsubstituted carbon ring group, and B denotes a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted aryl group. The optical recording medium may further comprise a recording layer capable of recording and/or reproducing information by irradiation of a laser beam. The present invention further relates to a method of recording visible information on the visible information recording layer of the optical recording medium, wherein the visible information is recorded by using the same laser bean as that used in recording on the above recording layer.
