PROBLEM TO BE SOLVED: To provide an ink jet recording material having good printer passability, blocking resistance, scratchability, ink absorbability of an ink acceptive layer and glossiness by using a vapor-phase method silica. SOLUTION: The ink jet recording material comprises an ink acceptive layer containing a vapor-phase method silica and coating a polyolefin resin- coated paper support. In this case, a ten-point mean roughness Rz specified according to a JIS B 0601 of a rear surface of the support is 12 to 40 μm under the condition of a reference length of 8 mm. Preferably, ridges of a sectional curve of the reference length is 10 or more. A ratio X/Y of a total sum X of the lengths of the mean lines crossing a part of the ridge to the total sum Y of the lengths of the mean lines crossing a part of a trough of the curve is in a range of 1/10 to 3/10. |
