PURPOSE:To sufficiently develop a full color without losing transparency even when printing is applied to a transparent base material by using specific alumina whose pore volume is set specifically as the ink receiving layer on a sheet. CONSTITUTION:A porous ink receiving layer is provided on a base material and mainly constituted of pseudo-boehmite and the total volume having a radius of 40 - below 100Angstrom thereof is 0.1 - below 0.4cc/g. Pseudo-boehmite has adsorption capacity of 20 - 100mg/g and the total volume of pores having a radius of 100 - 1,000Angstrom of the ink receiving layer is pref. 0.1cc/g or less. By this constitution, transparency is not lost even when printing is applied to the transparent base material and a full color can be developed. |
