Document Type and Number:
WIPO Patent Application WO/2017/138186
Kind Code:
A1
Abstract:
[Problem] To provide an ink jet recording medium that is excellent in ink drying characteristics when performing ink jet printing especially with pigment ink, provides high definition image quality and high color development, and has a feel and high glossiness of an offset printing type, and an ink jet recording method. [Solution] The ink jet recording medium has, on at least one surface of a base material, an ink receiving layer containing an inorganic pigment, starch, and a copolymer latex. The inorganic pigment contains engineered calcium carbonate and kaolin. Relative to the total of the inorganic pigment, the content of the engineered calcium carbonate is 50 mass% or more and less than 80 mass% and the content of the kaolin is 10 mass% or more and less than 50 mass%. In addition, the ink receiving layer contains 1 pts.mass or more and 10 pts.mass or less of an organic pigment having a glass transition point (Tg) of 20°C or more relative to 100 pts.mass of the inorganic pigment.
