An improved disposable diaper of the type having a relatively high elongation to tensile force property, an absorbent pad, and tape-tab fasteners coated with a peelable adhesive. The backsheet is reinforced by coating the mother\s bond region thereof with a material having high tensile strength and a low elongation to tensile force property relative to the backsheet material. The coating may be continuous or patterned and may be disposed on either the outwardly facing surface or the inwardly facing surface of the mother\s bond region of the backsheet. When applied to the inwardly facing surface, the coating material may be adhesive material and may secure the backsheet to the pad assembly of the diaper. The reinforcement of the backsheet improves the resistance of the backsheet to stretching and tearing when subjected to tensile forces during fastening and wearing, and to peeling forces when the tape-tab fasteners are being peeled open. Thus, the fasteners are refastenable.

In an improved disposable diaper of the type having an absorbent pad assembly secured to a substantially moisture impervious backsheet of relatively thin material having a relatively high elongation to tensile force property, and having peelable adhesive coated tape-tab fasteners wherein at least one of said tape-tab fasteners has a nonadhesive coated distal end portion to provide a mother\s grasping portion for facilitating removal of said diaper from a user, the improvement comprising a coating disposed on an inwardly facing surface of a mother\s bond region of said backsheet, said coating comprising a self-adhering coating material having a relatively high tensile strength and a low elongation to tensile force property relative to said backsheet.
