Abstract
There are disclosed an ink-jet recording material which comprises a water resistant support, an ink-receptive layer containing inorganic fine particles having an average particle size of a primary particle of 3 to 30 nm on one surface of the support, and a back coating layer mainly comprising an organic polymer provided on an opposite surface of the support to the surface on which the ink-receptive layer is provided, wherein when an arithmetical mean roughness Ra measured with a cut off value of 0.8 mm regulated by JIS-B-0601-1994 of the surface on which the back coating layer has been provided of the water resistant support is made A &mgr;m, a density of the organic polymer in the back coating layer is made B g/cm3, and an amount of a solid component of the organic polymer provided as the back coating layer is made C g/cm2, then A is 1 to 5 &mgr;m and A, B and C satisfy the following formula (I):0.6×A<C/B<6  (I)a recording method and a recorded material using the same.
