Abstract
Inkjet printing is carried out to provide monochrome or polychrome inkjet-printed images. An ink-receptive medium is provided with a substrate with an aqueous-based ink-receptive layer disposed thereon. The aqueous-based ink-receptive layer has: (a) one or more water-soluble salts of a multivalent metal cation in an amount of 0.6-49 weight %; (b) one or both of a polyvinyl alcohol and a polyvinyl amine (or a copolymer of a vinyl alcohol and vinyl amine) in a total amount of 0.5-30 weight %; and optionally, (c) a crosslinking agent and (d) silica particles. One or more aqueous pigment-based inks are inkjet printed onto this aqueous-based ink-receptive layer, each ink comprising: a) one or more anionically-stabilized pigment colorants; b) one or more water-miscible humectants that are present in a total amount of 1-20 weight % and each having a carbon atom to oxygen atom ratio of at least 1.0:1.0 and only two hydroxy groups.
