Patent ID: 8257804

Claim:
A recording medium comprising: a substrate; two or more ink receiving layers disposed on a first surface of the substrate; and two or more ink receiving layers disposed on a second surface of the substrate, the second surface being opposite the first surface, wherein the ink receiving layers each contain a pigment and a binder; the relationships (1) A 1 >A 2 , (2) B 1 >B 2 , and (3) |A 1 −B 1 |≦1.0 are satisfied, where A 1 is the peak (in units of nm) of the pore radius distribution of the outermost ink receiving layer on the first surface side, A 2 is the peak (in units of nm) of the pore radius distribution of the ink receiving layer adjacent to the outermost ink receiving layer on the first surface side, B 1 is the peak (in units of nm) of the pore radius distribution of the outermost ink receiving layer on the second surface side, and B 2 is the peak (in units of nm) of the pore radius distribution of the ink receiving layer adjacent to the outermost ink receiving layer on the second surface side; and the arithmetic average roughness Ra, which is specified in JIS B 0601, of each of the outermost ink receiving layer on the first surface side and the outermost ink receiving layer on the second surface side is 0.50 μm or more.
