Abstract: The present invention relates to a method of forming an image on a substrate comprising a transparent or translucent composition applied thereto, wherein the transparent or translucent composition comprises a protein in a non-denatured state, and the method comprises applying radiation to the transparent or translucent composition to denature the protein and thereby form an image on the substrate. The invention also relates to a method of preparing a substrate on which an image can be formed, and related substrates, compositions and uses thereof.
