An aqueous coating formulation for use in preparing ink jet recording materials is provided. The coating formulation, which employs porous pigments and/or metal oxide gels in combination with inorganic pigments (i.e., calcium carbonate and mixtures of calcium carbonate and alumina), has a relatively high binder-to-pigment dry weight ratio. An ink jet recording material prepared using such an aqueous coating formulation is also provided. The ink jet recording material demonstrates good printability and provides images having excellent water and humidity resistance and high image densities. In a preferred embodiment, the inventive recording material further demonstrates good light or fade resistance.

Ink jet recording material suitable for use in wide format printing applications

An ink jet coating composition comprising a blend of silicas, a blend of super and/or fully and partially hydrolyzed polyvinyl alcohols, and a cationic resin is provided, where ink jet recording materials prepared from such compositions demonstrate a balance of properties including improved imaging performance and good water resistance.
