Abstract:
1. A production process for a water-absorbing agent, which comprises the step of blending 100 parts by weight of water-absorbent resin particles (A) and 0.01 to 10 parts by weight of a cationic polymer compound (B) together, wherein the cationic polymer compound (B) is obtained by a process including the step of crosslinking a cationic polymer with a crosslinking agent of which the amount is 0.01 to 10 weight % of the cationic polymer, and wherein the cationic polymer compound (B) has a water solubility of 70 to 10 weight % if the cationic polymer compound (B) is obtained from an ethylenimine monomer, otherwise the cationic polymer compound (B) has a water solubility of 100 to 10 weight %.
