摘要： 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.
