Abstract

The photosensitive spiroxazine dye having reactive anchor within the dye molecule was prepared to provide the durable coloration properties caused by covalent bonding system. Spiroxazine exhaustions to the polyamide substrates and its photochromic effects within the fiber molecules were investigated and effects of the reactive system of spiroxazine dyeing were discussed. Successful spiroxazine exhaustions within the fiber molecules were determined by photochromic properties of the dyed substrates. With UV irradiation, photochromic behaviors appeared on the substrates was that of blue color. In addition, in the case of spiroxazine dyeing having reactive group within the molecule, it showed photochromic color forming behavior even after the sample was subjected to extraction process.
