Patented is an absorbent article comprising an absorbent core, the absorbent core comprising a primary water-absorbing agent wherein the primary water-absorbing agent comprises (i) water-absorbing resin particles obtained by polymerizing an acid group-containing unsaturated mono_mer; (ii) a compound that includes a constitutional unit derived from poly__alkyleneglycol, that is different from the unsaturated monomer; and (iii) a polyvalent metal salt. The primary water-absorbing agent exhibits a Centrifuge Retention Capacity of from about 5 to about 20 g/g; and the compound is present without forming a chemical bond with the water-absorbing particles and/or the compound is separable from the water-absorbing particles.
