Primer compositions containing an optical brightener and inkjet printing methods associated therewith

Abstract

Primer compositions containing an optical brightener may be utilized to increase the vibrancy of ink images that are subsequently deposited upon a print substrate. Such primer compositions may comprise an aqueous fluid, a metal salt dissolved in the aqueous fluid, and an optical brightener dissolved in the aqueous fluid. The primer compositions may be deposited upon at least a portion of a print substrate, and the aqueous fluid may be evaporated to form a primer coating upon the print substrate. An ink may then be deposited in an imagewise pattern upon at least a portion of the primer coating.
