    摘要： An inkjet receiving media comprising a substrate having a transparent topmost layer coated thereon at solid content of from 0.3 to 2.5 g/m2, wherein the topmost layer includes from 30-70 wt % of one or more aqueous soluble salts of multivalent metal cations, 5 to 20 wt % of a cross-linked hydrophilic polymer binder, 4 to 12 wt % of a cationic polymer to stabilize 10 to 40 wt % silica that is less than 200 nm is size. Improved optical density, reduced mottle and improved wet abrasion resistance are provided when the receiver is printed with an aqueous pigment-based ink. In further embodiments, the topmost layer can further include high levels of silica that makes the layer porous.
