The coating composition comprises inorganic oxide, e.g., silica, in combination with a binder system comprising a mixture of a water soluble polymer and a non-ionic latex polymer. The composition may contain optional dye mordant (e.g., cationic polymer). It is found that the combinations of these components result in relatively high solids formulations (e.g., greate r than 20 % by weight) with relatively low viscosity (less than 5000 centipoise), do not exhibit coating dusting, and give exceptional ink-jet printability. These formulations are especially suitable for preparing on-li ne formulations because they can be formulated to have a viscosity less than 20 00 centipoise. Preferable embodiments for on-line coatings have a viscosity les s than 1000 centipoise.
