Abstract
Saturated paper products characterized by an excellent balance of toughness, strength, fold, tear and delamination resistance comprising a sheet of loosely bonded cellulose fibers saturated with an aqueous emulsion prepared by the emulsion polymerization of: PA1 (a) a vinyl ester of an alkanoic acid interpolymerized with: PA1 (b) 5 to 30% by weight of ethylene; PA1 (c) 0.5 to 6% by weight of an N-methylol containing copolymerizable monomer; PA1 (d) 1 to 5% by weight of an olefinically unsaturated carboxylic acid; PA1 (e) 0.2 to 3% by weight of a latex stabilizer; and PA1 (f) 0 to 1% by weight of at least one polyunsaturated copolymerizable monomer.
