| 摘要 | A recording medium includes, in sequence, a support; a first ink-receiving layer including an inorganic particle, a water-soluble polymer having a hydroxyl group, a water-soluble polymer not having a hydroxyl group, and a boric acid compound; and a second ink-receiving layer including an inorganic particle, a water-soluble polymer having a hydroxyl group, and a boric acid compound. The second ink-receiving layer does not include the water-soluble polymer not having the hydroxyl group, or the second ink-receiving layer includes the water-soluble polymer not having the hydroxyl group but the content of the water-soluble polymer not having the hydroxyl group relative to that of the inorganic particle in the second ink-receiving layer is smaller than the content of the water-soluble polymer not having the hydroxyl group relative to that of the inorganic particle in the first ink-receiving layer. | ||

| 主权项 | 1. A recording medium comprising: a support; a first ink-receiving layer; and a second ink-receiving layer in that order, wherein the first ink-receiving layer includes an inorganic particle, a water-soluble polymer having a hydroxyl group, a water-soluble polymer not having a hydroxyl group, and a boric acid compound, and the second ink-receiving layer includes an inorganic particle, a water-soluble polymer having a hydroxyl group, and a boric acid compound, and satisfies a condition (1) or (2) below: Condition (1): The second ink-receiving layer does not include the water-soluble polymer not having the hydroxyl group. Condition (2): The second ink-receiving layer includes the water-soluble polymer not having the hydroxyl group, but the content of the water-soluble polymer not having the hydroxyl group relative to the content of the inorganic particle in the second ink-receiving layer is smaller than the content of the water-soluble polymer not having the hydroxyl group relative to the content of the inorganic particle in the first ink-receiving layer. | ||
