Abstract
An aqueous composition can be used for pre-treating a substrate prior to inkjet printing to provide a white opaque background for inkjet-printed images. This aqueous composition includes: (a) one or more water-soluble salts of a multivalent metal cation at 5-30 weight %; (b) a nonionic or cationic water-soluble or water-dispersible polymeric binder material at 5-30 weight %; and (c) surface-treated visible light-scattering particles having a D50 (median) particle size of at least 0.04 μm and up to and including 2 μm in an amount of 5-60 weight % based on the total aqueous composition weight. The pre-treated substrate is useful as an inkjet receiving medium that can be readily inkjet-printed particularly with anionically-stabilized aqueous pigment-based inks.
