Ink-receiving print media products (10, 100, 200) having multiple capabilities including (A) minimal drying time; (B) improved smear-fastness; (C) the ability to generate high-definition images with desirable gloss characteristics and gloss-uniformity; and (D) excellent compatibility between the ink materials being delivered and the media products (10, 100, 200) along with other related benefits including the control of ink-coalescence. The print media products (10, 100, 200) of interest have at least one ink-receiving layer (30, 102) on a substrate (12) Äe.g. polyethylene-coated paperÜ, with the ink-receiving layer (30, 102) including a poly(vinyl alcohol-ethylene oxide) copolymer as a special multi-functional ingredient designed to produce the foregoing benefits. The copolymer may be employed alone or combined with one or more other ingredients in the ink-receiving layer (30, 102) including pigment(s), supplemental binder(s), and the like in order to fabricate an effective media product (10, 100, 200) ideally suited for inkjet image generation using a wide variety of inks.
