Abstract
The present invention relates to ink jet recording materials and method for making the same. The material has a gel layer formed on a base material to improve the optical density of the material and improve the printing quality of ink of pigment type. The method for forming the gel layer is to coat a first ink-receptive layer composed of high valance metallic halide, such as calcium chloride (CaCl ) or magnesium chloride (MgCl ), on the base layer, then a second ink-receptive layer composed of alginate, such as sodium alginate, potassium alginate or other compounds of alginic acid, on the first ink-receptive layer. The second and the first ink-receptive layers will react to form a gel layer during coating for absorbing ink dots and improving print quality.
