    • An inkjet recording sheet comprising a support and, on a surface of the support, a colorant-receiving layer formed by applying a first coating liquid, adding a second coating liquid, after application of the first coating liquid and before the same shows a decreasing rate of drying, and thereafter hardening and drying the coat layer to form a porous structure. The first coating liquid has a pH value of 5 or lower, and is obtained by adding a solution which includes polyvinyl alcohol, a nonionic surfactant and/or amphoteric surfactant and a high boiling point organic solvent, to a dispersion including a cationic resin and vapor-phase-process silica having a specific surface area of at least 200 m2/g as measured by the BET method. The second coating liquid has a pH value of 8.5 or higher and includes a cross-linking agent capable of cross-linking the polyvinyl alcohol, an organic mordant and a nonionic surfactant.

    • A first adhesion layer and a second adhesion layer are formed on a base material formed of polyester biaxially stretched in this order from the side of the base material. Additionally, a hard coat layer and an antireflection layer are formed on the second adhesion layer to form a multilayer film. When refractive indices of the base material, the first adhesion layer, the second adhesion layer, and the hard coat layer are η1, η2, η3, and η4, respectively, the refractive indices are adjusted so as to satisfy the following formulae (1) to (3) to prevent rainbow unevenness.
