PROBLEM TO BE SOLVED: To obtain a recording sheet for ink jet excellent in ink absorbency. SOLUTION: A porous structure is formed within the ink permeable layer 14 of the recording sheet 10. Since the total volume of fine pores having the radius of 100 nm or more and 10,000 nm or less is 0.06 cm3/g or more, the ink applied onto the surface of the ink permeable layer 14 is permeable longitudinally and quickly through the porous structure, resulting in developing hardly bleeding. In addition, as an ink absorbing layer 13 added with a hydrophilic resin has a large ink absorbing capacity, the ink transmitted the ink permeable layer 14 is absorbed in and fixed to the ink absorbing layer 13, resulting in not dispersing in the recording sheet 10. As a result, the recording sheet 10 is excellent in ink absorbency. No bleeding develops in the sheet printed by an ink jet system. In addition, the sheet has a high printing density. |
