| titleOfInvention | Photochromic article |
| abstract | ABSTRACT OF THE DISCLOSURE A photochromic article comprises a transparent matrix composed of a material selected from acrylic resins and urethane resins, a first photochromic compound dispersed in the matrix and consisting of a composition selected from chromene derivatives, a second photochromic compound dispersed in the matrix and consisting of a composition selected from fulgide or fulgimide compounds, and a dye for coloring the matrix. The dye is adopted to color the matrix either in the color developed by a photochromic compound, with the fastest color fading speed, among the photochromic compounds, or the complementary color of the color developed by a photochromic compound, with the slowest color fading speed, among the photochromic compounds, or the mixed color of the colors developed by all of the photochromic compounds. |
