Abstract
An ink jet recording sheet is disclosed which has excellent ink retention properties, color development properties, weather resistance and water resistance, and which is substantially free from curling even if it has its only one side provided with an ink receiving layer. In particular, the present invention relates to an ink jet recording sheet which is extremely suited for use in poster applications. The ink jet recording sheet comprises: a substrate having its at least one side provided with an ink receiving layer; the ink receiving layer containing a nonionic surfactant and a binder resin, solid content of the nonionic surfactant being in a range of 11% to 20% by weight of total solid content of the ink receiving layer, the binder resin containing a silanol group-modified polyvinyl alcohol as a component thereof in an amount of 70% by weight or more of solid content of the binder resin.
