Abstract
The present invention discloses a method of photolytically developing a colored image on a cellulosic material. In this method, the material is contacted with a nitrogen containing polymer in solution and a mono-sulfonyl azide compound in solution. The sample is thereafter exposed to a UV-containing light source for an amount of time sufficient to develop a color thereon.
