A foamable aqueous composition can be used to form foamed, opacifying elements. These compositions have: (a) 0.5 to 20 weight % of porous particles having a continuous polymeric phase and discrete pores dispersed therein. The porous particles have a mode particle size of 2 to 50 &#x3bc;m; (b) at least 20 weight % of a binder material; (c) 0.1 to 30 weight % of additives including dispersants, plasticizers, inorganic or organic pigments and dyes, thickeners, flame retardants, biocides, fungicides, optical brighteners, tinting colorants, metal flakes, and inorganic or organic fillers; (d) water; and (e) at least 0.001 weight % of an opacifying colorant different from (c). The foamable aqueous composition is suitably aerated, disposed on a porous substrate, dried, and crushed on the porous substrate. The method can be used to provide such elements with one or more dry foamed layers.

Method of making foamed, opacifying elements

A method for providing a foamed, opacifying element includes providing a foamable aqueous composition, aerating it to a foam density of 0.1-0.5 g/cm, applying the foamed aqueous composition to a porous substrate, drying, and densifying the dried layer. Such foamable aqueous compositions have 0.05-15 weight % of porous particles; at least 20 weight % of a binder; at least 0.0001 weight % of additives (including a surfactant); water; and at least 0.001 weight % of an opacifying colorant. Each porous particle includes a continuous polymeric phase and discrete pores; a mode particle size of 2-50 &#x3bc;m; and a porosity of 20-70 volume %. The continuous polymeric phase Tis &#x3e;80&#xb0; C. and has a polymer viscosity of 80-500 centipoises at an ethyl acetate shear rate of 100 secat a concentration of 20 weight % at 25&#xb0; C.

Method of making light-blocking high opacity articles

An inkjet receiving media comprising a substrate having a transparent topmost layer coated thereon at solid content of from 0.3 to 2.5 g/m, wherein the topmost layer includes from 30-70 wt % of one or more aqueous soluble salts of multivalent metal cations, 5 to 20 wt % of a cross-linked hydrophilic polymer binder, 4 to 12 wt % of a cationic polymer to stabilize 10 to 40 wt % silica that is less than 200 nm is size. Improved optical density, reduced mottle and improved wet abrasion resistance are provided when the receiver is printed with an aqueous pigment-based ink. In further embodiments, the topmost layer can further include high levels of silica that makes the layer porous.
