Abstract

The photochromic dye(spiroxazine, Blue) as a susceptible material was synthesized by condensing 1-nitroso-$\beta$-naphthol with indoline. The melting point of the synthesized spiroxazine dye was 254$^{\circ}C$. Irradiation with ultraviolet light had effect on reversible coloration reaction. The photochromic dye microcapsules were produced by in situ polymerization using urea-formaldehyde prepolymer. The average diameter of the microcapsule was 2.94$\mu$m. The dyeability and washing fastness of the photochromic microcapsule fibers were increased by the pretreatment of cationic agent.
