Abstract
An aqueous ink receptive primer composition is useful for pre-treating a water-absorptive substrate to prepare or prime the resulting inkjet receiving media for high quality and potentially high-speed inkjet printing. This aqueous ink receptive primer composition has 8-25% solids, and includes (a) one or more water-soluble salts of a multivalent metal cation, in a total amount of 0.1-30 weight %; (b) one or more water-soluble or water-dispersible polymeric binder materials in a total amount of 1-20 weight %, each having a Mw of 50,000 to 180,000; and (c) fluorine-free wax particles composed of a water-insoluble composite that comprises one or more polymers comprising a polyalkylene, a polyester, or a polyimide, in an amount of 0.1-2 weight %. The noted composition on the water-absorptive substrate allows high-speed inkjet printing with reduced ink misting while maintaining high inkjet-printed image quality.
