  • Patent number: 7405341
    Abstract: The present invention relates to absorbent articles comprising superabsorbent polymer particles. The superabsorbent polymer particles are coated with cationic polymers having 1 to 25 mol/kg, referring to the total weight of the cationic polymers, of cationic groups, which can be protonated. The cationic polymers are not substantially covalently bound to the superabsorbent polymer particles. Furthermore, the superabsorbent polymer particles are not substantially covalently surface cross-linked.

  • Publication number: 20070202772
    Abstract: An absorbent article comprising an absorbent core, which comprises at least one region comprising an aqueous-liquid-absorbing agent that contains water-absorbent resin particles, wherein the water-absorbent resin particles are obtained by a process including the step of polymerizing a water-soluble ethylenically unsaturated monomer having a carboxyl group, in the presence of an internal-crosslinking agent having at least four functional groups each capable of forming a covalent bond with a carboxyl group to thereby obtain a hydropolymer that is internally cross-linked and surface-crosslinked, the aqueous-liquid-absorbing agent being characterized by exhibiting a water absorption capacity (CRC) of 5 to 25 g/g and a saline flow conductivity (SFC) of not less than 1216 cm3·s·10-7/g.
