Abstract
The present invention relates to a pressure-sensitive hot-melt adhesive composition characterized in that it includes a) at least one ethylene-alkyl acrylate copolymer, b) a tackifying resin and c) optionally a diluent and/or a stabilizer and/or a wax. Such a composition may be employed advantageously in the field of hygiene, especially for the adhesive bonding of disposable nappies and of catamenial liners.
