Novel hot melt construction adhesives for disposable articles, such as diapers, sanitary napkins, medical gowns, surgical drapes, and the like, are described which offer superior properties versus currently available hot melt adhesives. These hot melt construction adhesive compositions comprise a blend of styrene-isoprene block copolymer containing at least about 25 weight percent styrene and styrene-butadiene block copolymer containing at least about 25 weight percent styrene, at least one compatible tackifying resin and at least one plasticizer. The hot melt construction adhesive possesses a viscosity no greater than about 25,000 mPa·s at about 140° C., a shear adhesion failure temperature of at least about 60° C., and a static shear time to failure of no less than about 25 hours at about 23°.
