摘要： A method of forming an image on a substrate, which comprises applying to the substrate an activatable colour forming compound wherein said activatable colour forming compound is initially unreactive but becomes reactive upon activation; activating said colour forming compound in the areas of the substrate where the image is to be formed, and, reacting the activated colour forming compound into its coloured form to produce an image. A substrate imaged using this method is also provided.
