A recording sheet with an ink-receptive layer which can be used not only for dye type inks but also for pigment type inks is provided. Also provided is a coating liquid for forming an ink-receptive layer. The recording sheet with an ink-receptive layer includes a substrate sheet and an ink-receptive layer formed thereon, wherein the ink-receptive layer includes (i) fibrous crystalline particles on surfaces of which a cationic hydrated metal compound is supported and (ii) a binder. The fibrous crystalline particles have an average fiber diameter (D) of 0.1 to 2 &#x3bc;m, an average fiber length (L) of 1 to 200 &#x3bc;m and a ratio (aspect ratio) of an average fiber length (L) to an average fiber diameter (D) of 5 to 500.
