A saturated hydroentangled fibrous web which includes a fibrous web having a plurality of entanglement loci as a consequence of subjecting the fibrous web to high pressure liquid jets and a saturant which is present in the hydroentangled fibrous web at a level of from about 10 to about 100 percent, based on the dry weight of the fibers. The saturant is adapted to render the saturated paper durable and ink jet printable. The fibrous web is composed of fibers, in which from about 20 to 100 percent by weight, based on the total weight of the fibers, are cellulosic fibers; from 0 to about 70 percent by weight, based on the total weight of the fibers, are mercerized cellulosic fibers; and from about 80 to 0 percent by weight of the fibers, based on the total weight of the fibers, are synthetic polymer fibers. The saturant includes from about 98 to about 70 percent, on a dry weight basis, of a latex reinforcing polymer having a glass transition temperature of from about -40 DEG C. to about 25 DEG C.; and from about 5 to about 70 percent, on a dry weight basis, of a cationic polymer. Either or both of the latex reinforcing polymer and the cationic polymer have crosslinkable functional groups. In addition to the fibrous web, a bonded nonwoven may be present. |
