摘要 |
Disclosed is a photo-responsive liquid crystal composition which is composed of a liquid crystalline compound and a gelling agent, an information-recording medium and an information-recording process making use of the information-recording medium. The gelling agent consists of a photochromic compound having a group capable of forming an intermolecular hydrogen bond in its molecule as well as a photo-responding site of a specific structure. The composition can exist in any state of gel of a first phase and gel of a second phase and can undergo changes in state between the gel of the first phase and the gel of the second phase. The information-recording medium has a recording layer formed of the composition, and the information-recording process utilizes changes in state between the gel phases in the recording layer. |
