<p>A plate material for printing in which a film (4) of an orgaic compound having a hydrophobic group is formed on the surface of a photosensitive layer (3) containing a photocatalyst responsive to not only UV-rays but also visible light, whereby the plate material for printing can be used repeatedly by writing an image onto the surface of the plate material through irradiation with visible light and regenerating the surface of the plate material through erasure of the image thus written.</p> |
