INK JET RECORDING PAPER

摘要

PROBLEM TO BE SOLVED: To provide an ink jet recording paper of high quality which is excellent in image deterioration-preventive effect by noxious gas irrespective of storage conditions.

SOLUTION: A surface layer containing an organic fine particle A or an organic fine particle B and one or more porous layers are provided on a non- absorbing base material. An inorganic fine particle of <20 nm in average particle size of a primary particle is contained in the surface layer to provide the ink jet recording paper. The organic fine particle A is the 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 the organic fine particle having a polymer containing ≥5 mass% of repeating unit represented by general formula (1) as copolymer component. They are respectively an organic fine particle of ≥70°C in glass transition temperature (Tg) and ≤100 nm in average particle size.
