Abstract
A method for making a relief pattern of a cured resin on a transparent colored layer which comprises applying a coating of a photocurable resin composition whose spectral sensitivity varies depending on the pH of the composition, on a transparent colored layer, adjusting the pH of the composition to a predetermined level, and exposing the coating to visible light irradiation through the transparent colored layer. The irradiated layer is developed to obtain a relief pattern corresponding to visible spectra transmitted through the transparent colored layer.
