Patent ID: 7521101

Claim:
An ink jet recording media system that comprises a support and one or more coating layers thereon, wherein at least one coating layer comprises a copolymer or cooligomer that comprises monomer units derived from at least one monomer selected from the group consisting of the acrylate and acrylamide monomers, at least one monomer selected from the group consisting of the amine containing ethylenically unsaturated monomers, at least one monomer selected from the group consisting of the polyacrylates of polyols and at least one associative monomer selected from the group consisting of stearyl ethoxy (20) methacrylate, stearyl ethoxy (10) allyl ether, poly(ethylene glycol)(meth)acrylate, poly(ethylene glycol)monomethyl ether mono(meth)acrylate, poly(ethylene glycol)acrylate and poly(ethylene glycol)monomethyl ether monoacrylate, which copolymer or cooligomer is at least partially neutralized with acid and in which the at least one coating layer has a pH of from about 3 to about 7 measured in water prior to drying.
