| titleOfInvention | Compound, polymerizable liquid crystal composition, optical element, and optical information recording / reproducing apparatus |
| abstract | Provided are a compound having good light resistance and obtaining desired liquid crystallinity after polymerization, and a polymerizable liquid crystal composition containing the compound. Also provided are an optical element with good light resistance and an optical information recording / reproducing apparatus using the optical element. CH 2 = CR 1 -COO-R 2 -Cy-Ph-R 3 compound represented by -OCO-CR 4 = CH 2. R 1 and R 4 are preferably hydrogen atoms. R 3 is an alkylene group having 1 to 15 carbon atoms which has or does not have an oxygen atom at the terminal bonded to the ring group, and a part or all of the hydrogen atoms bonded to the carbon atom in the group are substituted with fluorine atoms. It is preferably an alkylene group which may be substituted, or an alkylene group having an oxygen atom at the terminal bonded to the ring group. Since the diffraction grating (2) manufactured using this liquid crystalline compound has good light resistance, a blue laser is used as the light source (1) to provide an optical information recording / reproducing apparatus suitable for increasing the capacity. it can. |
