Abstract
The objective of this invention is to provide a recording material that can be recorded by ink with water-soluble dye, particularly to provide an ink jet recording sheet, which provides an excellent combination of in ink absorbency, ink coloration, light resistance, water resistance and surface gloss.One subject of the invention is an ink jet recording sheet having on an ink-receiving support an image preserving layer comprising anionic colloidal silica and zinc oxide particulates with an average particle size of about 15 to 380 nm and having a 75 degree specular glossiness of at least about 25% at the surface. Another subject of the invention is an ink jet recording sheet having on an ink-receiving support, in succession, an image preserving layer comprising anionic colloidal silica and zinc oxide particulates with an average particle size of about 15 to 380 nm and a fixing layer comprising cationic colloidal silica and cationic polymer electrolyte.
