INK JET RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an ink jet recording medium which is excellent in fading resistance due to noxious gas even though it is preserved under various circumstances.

SOLUTION: A front layer containing an organic fine particle A or an organic fine particle B which are difined as follows and at least one layer of porous layers are provided on a film substrate to provide the ink jet recording medium. The organic fine particle A is an organic fine particle insoluble in water and soluble in or swollen by a water soluble organic solvent of 18.414-30.69 (MPa)1/2in SP value and ≥120°C in boiling point. The organic fine particle B is an organic fine particle having a polymer containing ≥5 mass% of a repeating unit represented by general formula (1) as a copolymer component. They are respectively an organic fine particle of ≥70°C in glass transition temperature (Tg) and ≤100 nm in average particle size.
