description The present invention refers to a recording medium having an ink-receiving layer comprising an alumina hydrate and an acid-processed gelatin, wherein the acid-processed gelatin is a modified gelatin with at least some blocked carboxylic groups. The viscosity of the dispersion doesn't abruptly increase and the dispersing state remains good. In addition, the use of said dispersion provides the advantage to obtain an ink-receiving layer with proper thickness, with a glossy surface and free of defects, such as cracks or microcoagulations.
