| titleOfInvention | Novel spiropyran compound |
| abstract | NEW MATERIAL:A compound of formula I (R 1 WR 4 are H or 1W6C alkyl; R 5 and R 6 are OH, NH 2 , organic-substituted amino, 1W6C alkoxy, 7W11C aralkoxy, 6W10C aryloxy, halogen, CN, etc.; l and m are 0W4; n is 1W6). n EXAMPLE: 1'-Carbamoylmethyl-3', 3'-dimethyl-6-nitrospiro [2H-1-benzopyran-2,2'- indoline]. n USE: A photochromic material for printing and optical instrument, etc. It has high rate of color development and extinction and excellent acid resistance and is stable even in an organopolysiloxane system. It is added to a resin at an amount of preferably 0.01W10wt%. n PREPARATION: The objective compound can be produced e.g. by reacting a compound of formula II (e.g. 1-carbamoylmethyl-2-methylene-3,3-dimethylindoline) with a compound of formula III (e.g. 5-nitrosalicylaldehyde) in a solvent such as ethanol. n COPYRIGHT: (C)1987,JPO&Japio |
