PHOTOCHROMIC COMPOSITION RESISTANT TO FATIGUE INCLUDING SPIRO [INDOLINE-2,3'-[3H]-NAPHTH [2,1-B][1,4]OXAMINE](SO) DYE AND ULTRAVIOLETSTABILIZER |
| 摘要 |
<p>PHOTOCHROMIC COMPOSITION RESISTANT TO FATIGUE The organic photochromic composition of this invention comprises spiro ¢indoline-2,3'-¢3H!-naphth ¢2,1-b! ¢1,4! oxazine! (SO) dye and an unconventional ultraviolet stabilizer. The ultraviolet stabilizer improves the light fatigue resistance of the SO dye and will not hinder the photocolorability of the photochromic composition.</p> |
