ABSTRACT:
A coating composition for an ink jet recording medium comprises an aqueous suspension of absorptive silica pigment, a polyvinyl alcohol binder, and a cationic fixing agent. The composition is dispersed at pH values in the range of 4.0 to 7.0. The pigment is preferably a mixture of 75% or more silica gel having a pore volume of 0.5-1.5 cc/g, and 10% or more alumina or alumina hydrate. A method for making down the coating composition and applying it to a substrate is also disclosed.
