In a preferred embodiment, the cellulosic fibers contain a polysaccharide in which the hydroxyl groups of at least a portion of the repeating units of the polysaccharide are cis-hydroxyl groups, preferred repeating units being mannose and/or galactose. Similarly, the water-soluble polymer is preferably a polysaccharide in which the hydroxyl groups of at least a portion of the repeating units of the polysaccharide are cis-hydroxyl groups. Preferred polysaccharides are derived from one or more sugars selected from mannose, galactose, allose, altrose, gulose, talose and lyxose.

[ What is claimed is:] [1.]1. A paper product comprising paper having an initial total wet tensile strength of at least about 80 g/inch and a 30 minute total wet tensile strength of not more than about 40 g/inch, wherein said paper comprises bleached cellulosic pulp fibers whereby said bleached cellulosic pulp fibers are modified to contain free aldehyde groups said free aldehyde groups formed by the reaction of said bleached cellulosic pulp fibers with an oxidizing agent so as to convert a portion of the hydroxyl groups of said bleached cellulosic pulp fiber to aldehyde groups, said bleached cellulosic pulp fibers combined with a water-soluble polymer having functional groups capable of reacting with said free aldehyde groups, said free aldehyde groups being reacted with said functional groups to form chemical bonds joining said fibers.
