外広告物の用途に広く使用することができる。By laminating an image concealing layer on the back surface of the fiber base material via an adhesive layer, it is possible to prevent the image from being transparent, and the amount of the binder relative to the inorganic filler in the ink absorbing layer. By increasing the amount of the above, a sheet for ink jet recording with improved coating film strength can be obtained. Since the obtained ink jet recording sheet has excellent weather resistance and water resistance, it can be widely used particularly for outdoor advertising.
