Photochromic fabric can change color when exposed to a certain light wavelength. The fabric can reversibly restore to its original color after the light disappears. In this study, two spirooxazines with photochromic properties, i.e., Nmethyl- 3,3-dimethyl-9'-hydroxy-spiro [2H-indole-2-[3H] naphtho [2,1-b] [1,4] oxazine] (Spirooxazine A) and N-methyl-3,3-dimethyl-9'-dichloro-s-triazine group spiro [2H-indole-2'-[3H] naphtho [2,1-b] [1,4] oxazine] (Spirooxazine B), were synthesized. The spirooxazines were characterized by Fourier transform infrared (FTIR) and ultraviolet (UV) spectrophotometers. Spirooxazines A and B were used to dye cotton fabrics under ultrasonic irradiation. The results show that cotton fabric dyed with Spirooxazine B has excellent photochromic properties, and better fading time and fatigue resistance.
