| titleOfInvention | Photochromic compound |
| abstract | NEW MATERIAL:The compound of formula (R 1 is substituent having saturated hydrocarbon ring as a principal skeleton; R 2 WR 5 and R 9 WR 14 are lower alkyl, nitro, etc.; R 6 and R 7 are H, benzyl, etc.; R 8 is H, lower alkyl, etc.; n is integer of 1W30). n EXAMPLE: 1-Cyclohexylmethyl-3,3,4,6-tetramethylspiro[indolino-2,3'-(9'-methoxyna phtho)[2,1-b][1,4]-oxazine]. n USE: A photochromic material having high molar extinction coefficient and excel lent durability and temperature characteristics, etc., of color-development. n PREPARATION: The exemplified compound can be produced e.g. by reacting 2,3,3,4,6-pentamethylindolenine with (bromomethyl)cyclohexane and reacting the resultant 1-cyclohexylmethyl-2,3,3,4,6-pentamethylindolenine bromine salt with 7-methoxy-1-nitroso-2-naphthol. n COPYRIGHT: (C)1988,JPO&Japio |
