PROBLEM TO BE SOLVED: To form a film of good strength, provide superior quick drying properties, water absorbability and water resistance and also provide a glossy high quality picture by using a silica particle surface layer doped with alumina as an inorganic pigment used for an ink acceptive layer of pore absorption type. SOLUTION: A structure of forming a porous layer as an ink acceptive layer 2 of pore absorption type on a substrate 1 is provided. As for the substrate 1, a transparent or an opaque film can be used. The surface treatment such as the easy boding treatment is applied on the surface of the substrate 1 so that an ink acceptive layer 2 can be formed easily, or an anchor coating layer can be formed thereon. An adhesive layer, a writing layer or the like can be formed on the face of the substrate 1 opposite to the face on which the ink acceptive layer 2 is formed for the purpose of setting off, writing or some other use onto another member. The ink acceptive layer 2 is an ink acceptive layer of porous absorption type composed mainly of an inorganic pigment, and as the inorganic pigment, aluminum doped silica particles are used and superior fluid flowing properties and dispersion properties are provided thereon. |
