Patent ID: 7713599

Claim:
An ink jet recording material formed by coating a coating solution of a pigment layer and a coating solution of at least one ink-receiving layer in succession on at least one side of a paper support and drying the resulting coating layers, wherein the pigment contained in the pigment layer has an average secondary particle diameter of not less than 1 μm and not more than 5 μm, 50% by volume or more of the total volume of the pigment has a secondary particle diameter of not less than 1.2 μm and not more than 15 μm, a first ink-receiving layer directly coated on the pigment layer contains at least inorganic ultrafine particles, a hydrophilic binder and boric acid or a borate, and the dry coating amount of the first ink-receiving layer is not less than 20% by mass and not more than 120% by mass of the dry coating amount of the pigment layer, wherein the inorganic ultrafine particles contained in the first ink-receiving layer are an alumina hydrate, and wherein a second ink-receiving layer coated on the first ink-receiving layer contains an alumina hydrate as inorganic ultrafine particles.
