Abstract
An inkjet receiving medium including a substrate and having a topmost layer coated thereon at solid content of from 0.1 to 25 g/m2, wherein the topmost layer comprises from 30-70 wt % of one or more aqueous soluble salts of multivalent metal cations and at least 0.05 g/m2 of a cross-linked hydrophilic polymer binder. 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 may further comprise a latex dispersion for improved image durability.
Claims17
An inkjet receiving media comprising:
- a substrate that is a glossy, semi-glossy, or matte-coated lithographic offset paper or polymeric film, which substrate that provides a hydrophobic surface that is substantially impermeable to water or aqueous ink,
- the inkjet receiving media further comprising a topmost layer that provides a continuous hydrophilic surface that is aqueous inkjet ink receptive and is coated on the substantially water or aqueous ink impermeable surface of the substrate at a solid content of from 0.2 to 3 g/m2,
- wherein the topmost layer comprises from 30-70 wt % of one or more aqueous soluble salts of multivalent metal cations, at least 0.05 g/m2 of a cross-linked hydrophilic polymer binder, and latex polymer filler in an amount that does not exceed 75% of the total polymer in the topmost layer.
