PURPOSE: To achieve accurate, sharp printing and obtain excellent weather- resistance which allows outdoor use, by forming a surface layer having boehmite as its main constituent onto a base material comprised of a fiber material coated with porous particles having a specific particle diameter. CONSTITUTION: An ink jet recording medium which is suitable as a cloth base material is obtained by forming a surface layer having boehmite as its main constituent onto a base material comprised of a fiber material coated with porous particles having a particle diameter of 0.1-30μm. Below the surface layer mainly comprised of the boehmite is a cationic resin layer, and the rear of a surface on which images are to be recorded is a hydrophobic resin layer. When the images are being recorded, the porous particles compensate for the ink absorption capacity of a fiber material, such as synthetic fiber, in which an amount of ink that the fiber itself absorbs is small, and also it prevents ink from passing through a coarse fiber material. As the porous particles, an inorganic substance, such as silica, clay, or alumina, and an organic substance, such as cellulose, are used. |
