This invention is directed to absorbent structures and preferred absorbent articles, comprising solid, typically particulate, water-swellable material that comprises coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g. water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet- extensible material that has a tensile stress at break in the wet state of at least 1MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material.

La présente invention concerne des structures absorbantes et des articles absorbants préférés, comprenant un matériau gonflable dans l'eau, généralement particulaire, solide, lequel comprend des polymères gonflables dans l'eau, revêtus, de préférence, des polymères formant un hydrogel, lesquels sont revêtus d'un agent de revêtement qui est tel qu'il ne se rompt pas lorsque les polymères gonflent dans un liquide, par exemple de l'eau ou de l'eau saline. Par conséquent, l'agent de revêtement est extensible à l'état mouillé et présente une contrainte de traction à la rupture à l'état mouillé d'au moins 1MPa. Généralement, l'agent de revêtement comprend un matériau polymère élastomère.
