Abstract: Coatable compositions for formation of ink-receptive layers, which may be aqueous suspensions, comprise a mixture of: a) colloidal silica particles; b) polyester polymers; c) polymers selected from the group consisting of polyurethane polymers and (meth)acrylate polymers; and d) crosslinkers. Ink-receptive layers, which may exhibit high gloss and high ink anchoring are also provided, as are constructions comprising such layers.

Abstract: Coatable compositions for formation of ink-receptive layers, which may be aqueous suspensions, comprise a mixture of: a) 8.0-75 wt % (based on the total weight of a), b), c), and d)) of colloidal silica particles having an average particle size of 2.0-150 nm; b) 10-75 wt % of one or more polyester polymers; c) 10-75 wt % of one or more polymers selected from the group consisting of polyurethane polymers and (meth)acrylate polymers; and d) 0-10 wt % of one or more crosslinkers. Ink-receptive layers, which may exhibit high gloss and high ink anchoring are also provided, as are constructions comprising such layers. Porous solids are also provided, comprising: a) 8.0-75 wt % of colloidal silica particles having an average particle size of 2.0-150 nm; and b) one or more water dispersible polymers.
