  • Printable substrates with improved dry time and acceptable print density by using monovalent salts
    Patent number: 8574690
    Abstract: An article in the form of 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; and a metal salt drying agent having at least about 20% by weight of one or more monovalent metal drying salts, wherein the metal salt drying agent is present on at least one of the first and second surfaces in an amount sufficient to provide a percent ink transferred (“IT %”) value equal to or less than about 65% and to provide a black print density value of at least about 1.45. Also, a method for treating the internally sized paper substrate having the HST value of from about 50 to about 250 seconds with the metal salt drying agent.
