Abstract
A recording medium includes a substrate and ink receiving layers including a first ink receiving layer and a second ink receiving layer in that order. The first ink receiving layer contains first inorganic particles including alumina and silica particles, and a first binder. In the first ink receiving layer, the mass ratio of the first binder to the first inorganic particles is from 0.13 to 0.33, and the mass ratio of the alumina particles to the silica particles is from 0.43 to 2.33. The second ink receiving layer contains second inorganic particles and a second binder. The mass ratio of the second binder to the second inorganic particles is from 0.05 to 0.30. The second ink receiving layer has a thickness from 2 μm to 10 μm, and the total thickness of ink receiving layers is from 10 μm to 30 μm.
