Abstract
Provided is an absorbent resin composition which has both improved absorbency under load and improved liquid permeability between swollen gels, which is free from blocking or discoloration during storage, and which does not generate any odors. The present invention is an absorbent resin composition containing: a crosslinked polymer (A) including, as an essential structural units, a crosslinking agent (b) and a water-soluble vinyl monomer (a1) and/or a vinyl monomer (a2) which produces the water-soluble vinyl monomer (a1) through hydrolysis; and a cationic organic polymer (c) having a number average molecular weight of 1,000,000 or higher, or a cationic organic polymer (B) that has a cationic group and that is obtained through polymerization of a monomer composition including, as essential components, a cationic monomer having an amino group (am) and/or a cationic monomer having a salt of an amino group (am).
