Abstract
The photochromic material of the invention is such that a composition having an organic photochromic compound dissolved or dispersed in a hindered amine-type compound is microencapsulated. The photochromic material of the invention is not deteriorated in photochromic properties and can be used for a wide range of applications even when coloring or decolorizing repeatedly occurs on intermittent irradiation in air or when it is continuously irradiated with light for a long term.
