Inkjet media coating with improved lightfastness, scratch resistance, and image quality

An inkjet receiver layer is constructed of an alumina-containing layer also containing a binder with an essentially binder-free, colloidal, cationic silica top-coat. The colloidal cationic silica topcoat provides improved image quality (color gamut and gloss) and increased resistance to scratching,...

Summary:An inkjet receiver layer is constructed of an alumina-containing layer also containing a binder with an essentially binder-free, colloidal, cationic silica top-coat. The colloidal cationic silica topcoat provides improved image quality (color gamut and gloss) and increased resistance to scratching, while maintaining a high absorption of ink.
