1. A fibrous substrate comprising fibers bonded with an emulsion polymer binder, said polymer comprising:

  • a) at least 50 percent by weight percent of vinyl acetate monomer units;

    b) 0 to 40 percent by weight of ethylene monomer units;

    c) 5 to 20 percent by weight of cross-linking monomer composition; and

    d) 0 to 40 percent by weight of other co-monomers,wherein said polymer binder provides a characteristic wet strength value of greater than 4,500 g/in.
