The invention provides a photochromic dye of a structure containing a common structure of spirooxazine series compounds and three substituents. The photochromic dye according to the invention exhibits characteristics of a high heat stability, good light fatigue resistance, high sensitivity, extremely degradation rate and the like. This photochromic dye can be formulated with suitable organic solvents and used as photochromic functional colorants under UV light excitation. Further, this photochromic dye can be synthesized and purified in simple steps with cheap raw materials and hence at a greatly lowered production cost.
