PURPOSE:To obtain an ink jet recording sheet having a specific sizing degree, a specific surface pH value, a specific amount of magnesium chloride adhered, a tough dye color tone, and improved water resistance by providing a function by which recorded pictures are formed by jetting an ink liquid containing an acid dye, water, and a wetting agent. CONSTITUTION:In an ink jet recording system in which an ink liquid containing at least one water-soluble dye of acid dyes and direct dyes, water, and a wetting agent is injected to form a recorded picture, a recording sheet having a sizing degree of 20sec or less, a surface pH value of 5-10, and 0.1-15g/m<2> of adhered amount of at least one of the halides, sulfates, and nitrates of magnesium or calcium is used for ink jet recording. Therefore, ink jet recorded pictures free of missing and bleeding even when wetted can be obtained. |
