Abstract
A liquid toner digitally printable media including: a paper substrate; and a toner receiving layer established on at least one surface of the paper substrate. The toner receiving layer includes: pigments, binders, and at least one of cationic polymers and metallic salts. The pigments are from 60 to 95% of total dry weight of the toner receiving layer. The pigments include a major pigment which is at least 60 weight percent of total pigment dry weight. The major pigment includes a rod-like pigment selected from the group consisting of ground calcium carbonate, precipitated calcium carbonate, other rod-like forms of calcium pigment, and combinations thereof.
