Abstract
Acidichromism of four photochromic spirooxazine compounds (SP) were investigated systematically. When hydroxyl group is introduced on the naphtho ring of spirooxazine, the spirooxazine compounds are found to have acidichromic properties in both acidic and basic solutions. Substituent effect on the absorption maximum of acidichromic products has been discussed. A comprehensive discussion of acidichromic, photochromic and thermochromic processes is included.Keywords
