Abstract

On décrit un article absorbant dans lequel un substrat n'absorbant pas l'eau est revêtu, sur au moins un côté, d'une seconde couche comprenant une composition absorbant l'eau. On peut appliquer cette couche absorbant l'eau en tant que matériau polymère préformé ou en tant que sirop pouvant durcir in situ afin de former le matériau absorbant l'eau.
