Abstract
The present disclosure provides a reusable and reimageable medium including a substrate coated with a photochromic polymer. The photochromic polymer has a glass transition temperature ranging from 30° C. to 150° C., such as from about 30° C. to about 100° C., and the coated substrate converts to a colored state when both UV light and temperatures ranging from 30° C. up to 100° C. are applied to the coated substrate. The present disclosure also provides a method for producing and using the reusable and reimageable medium.
