A simple image formation on cellulosic substrate with using a combination of patterned UV photooxidation reaction on cellulosic substrate and metal silver deposition reaction on the oxidized cellulose substrate has been studied. The color depth of the silver deposit on the substrate increased with increasing the integrated energy of UV irradiation. Assuming that the color depth of the deposit is proportional to the amount of aldehydes formed on the substrate, the photooxidation reaction of hydroxyl group on the cellulose substrate to aldehydes found to apparently follow the first order reaction kinetics.
