PURPOSE:To enhance hydrophilicity and prevent ground contamination from occurring, without requiring a pre-etching step, by using an inorganic pigment based on a mixture of alumina, silica, zinc oxide and acetic acid or acetic anhydride or an inorganic pigment based on a mixture of said mixture with kaolinite in providing an image-receiving layer. CONSTITUTION:A coating liquid comprising a pigment based on a mixture of alumina, silica, kaolinite and zinc oxide, acetic acid or acetic anhydride, a water-soluble binder and a water-resisting agent is applied to a base, followed by drying to provide an image-receiving layer. A water-resistant intermediate layer may be further provided between the base and the image-receiving layer. By this method, it is possible to enhance hydrophilicity while maintaining the high sensitivity of the image-receiving layer, to ensure excellent plate wear, and to provide water resistance without using a potential catalyst or a special PVA. |
