摘要：
The present invention relates to absorbent articles comprising superabsorbent polymer particles especially suitable for use in the fluid acquisition zone of the absorbent core. 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.
