Abstract:
1. An article comprising: a paper substrate having a first surface and a second surface; an internal paper sizing agent present in an amount sufficient to impart to the paper substrate an HST value of from about 50 to about 250 seconds; one or more optical brightening agents present in an amount below a “green over” effect excess but sufficient to impart to at least one of the first and second surfaces an ISO Brightness value of at least about 92; and a metal salt drying agent comprising a mixture of one or more multivalent metal drying salts and one or more monovalent metal drying salts and present on the at least one surface, wherein the metal salt drying agent is in an amount and has a molar ratio of multivalent cations to monovalent cations such that the at least one surface has a percent ink transferred (“IT %”) value equal to or less than about 65% and a black print density value of at least about 1.45, and wherein the molar ratio of multivalent cations to monovalent cations is in the range from about 3:1 to about 1:18.
