A method for preparing a coated paper, which comprises coating a silica coating solution on a flat and smooth die surface, closely contacting thereto a pseudo-boehmite layer of a paper substrate having the pseudo-boehmite layer thereon, followed by drying to form a silica layer on the pseudo-boehmite layer, and then releasing the paper substrate from the die to transfer the silica layer onto the paper substrate, wherein the formed silica layer has a 60.degree. specular glossiness of at least 30% as stipulated in ISO 2813.
A method for preparing a coated paper, which comprises coating a silica coating solution on a pseudo-boehmite layer of a paper substrate having the pseudo-boehmite layer thereon, and then pressing a heated flat and smooth die to the silica coated layer to form a silica layer having the surface flattened, wherein the formed silica layer has a 60.degree. specular glossiness of at least 30% as stipulated in ISO 2813.
