Liquid crystalline polyurethanes and a medium for optical data storage comprising the same |
| abstract |
Abstract The invention relates to a liquid-crystalline polyurethane having a side chain comprising a mesogenic group, giving a clear polyurethane which does not isomerise under the influence of light. Such liquid-crystalline polyurethanes are highly suited to be used for optical data storage. The invention further relates to infrared-sensitive liquid-crystalline polyurethanes and liquid-crystalline polyurethane compositions, films containing said liquid-crystalline polyurethanes or polyurethane compositions, and a device for optical data storage containing said liquid-crystalline polyurethanes or polyurethane compositions. |
