    摘要： An ink-jet media sheet imparting superior image quality and permanence is disclosed. Such a sheet may comprise a substrate consecutively coated with a porous ink-absorbing layer and a porous ink-receiving layer, where the specific surface area of the particulates of the ink-absorbing layer is less than that of the ink-receiving layer, e.g., the particulates are generally smaller in the ink-receiving layer. The porous coating layers can comprise semi-metal or metal oxide particulates and may further include other surface treatment or reactive groups having functional moieties to promote fixing and localizing printed colorants. Images printed on these media sheets exhibit good fastness to water, ozone, and humidity as well as improved color gamut and black intensity.

    摘要： A printable recording media containing a substrate; a pre-coat layer including more than about 60 wt % of one or more inorganic pigments by total dry weight of the pre-coat layer; a topcoating layer including more than about 60 wt % of one or more inorganic pigments; up to 25 wt % of binders and up to about 5 wt % of a combination of natural and synthetic rheology modifiers, by total weight of the top-coating layer, wherein the ratio of the amount of natural rheology modifiers to the amount of synthetic rheology modifiers is from about 90:10 to about 50:50. Also disclosed herein is a method for making such printable recording media.

    摘要： A printable recording media containing a base substrate; a pre-coat layer including more than about 60 wt % of one or more particulate inorganic pigments by total dry weight of said pre-coat layer; an ink-receiving layer, disposed on said pre-coat layer, comprising a mixture of about 10 to about 90 wt % of a first pigment including precipitated calcium carbonate particles, about 5 to about 60 wt % of a second pigment having a larger size and a different shape than said first pigment particles, and about 1 to about 50 wt % of a third pigment having a surface area of at least 50 m2/gram, wherein said weight percentages are by combined weight of the first, second and third pigments by total dry weight of said ink-receiving layer. Also disclosed herein is a method for producing printed images using said recording media.
