| titleOfInvention | Photochromic substance |
| abstract | PURPOSE: To obtain a photochromic substance which has a high capacity of absorbing the light in a long-wavelength region and excellent resistance to repeated use, and gives a photochromic optical material having an excellent light controlling function, by using a specified spironaphthoxazine compound. n CONSTITUTION: A spironaphthoxazine compound of the formula (wherein R 1 is H, a halogen, cyano, a 1W6C alkyl or 1W6C alkoxy; R 2 is a substituted arylalkyl, a 1W6C alkyl, a 2W6C alkoxyalkyl, etc.) is used as a photochromic substance.A spironaphthoxazine compound of the formula is synthesized by reacting 2,6-dihydroxy-1,5-dinitrosonaphthalene with a corresponding indoline compound. A photochromic optical material having an excellent light controlling function can be obtained by incorporating this photochromic substance into a matrix comprising an optically transparent resin. n COPYRIGHT: (C)1988,JPO&Japio |
