Abstract

An absorbent article comprising at least one double-sided coated fibrous web having a storage layer on one side and an acquisition layer on the other side and/or a combination of at least two adhering double-sided coated webs with the proviso that one web has a storage layer on both sides and the other web has an acquisition layer on both sides wherein said layers are obtained by (a) forming a blend comprising one or more monomers forming superabsorbent polymers, superabsorbent polymer particles, water, and one or more initiators, said blend having a viscosity of at least 20 mPas (measured at 20 °C in a Brookfield viscometer, spindle 02, 20 rpm) (b) applying said blend onto a fibrous web and (c) carrying out the polymerization of the monomers forming superabsorbent polymers and a disposable hygiene article containing said absorbent article.
