HIGH SOFTNESS, HIGH DURABILITY BATH TISSUE WITH TEMPORARY WET STRENGTH

A multi-ply bath tissue includes cellulosic microfibers and wood pulp fibers. The bath tissue has sufficient temporary wet strength resin to provide an initial Finch Cup cross-machine direction (CD) wet tensile of from about 2.5 to about 20 g/3 in. per pound of basis weight, decaying to less than 65% of the initial value in less than 15 minutes after immersion of the tissue in water, and a caliper of at least 5 mils per 8 sheets per pound of basis weight. At least one of the plies includes a plurality of fiber-enriched hollow domed regions having a relatively high basis weight, a plurality of connecting regions having a relatively lower basis weight forming a network interconnecting the fiber-enriched hollow domed regions of the sheet, and a plurality of transition regions transitioning from the connecting regions into the fiber-enriched hollow domed regions.
