A body fluid-absorbing article such as, for example, a disposable diaper is provided with at least one absorbent member comprising 50 to 99% by weight of a fibrous material and 50 to 1% by weight of an absorbent polymer, which absorbent member contains at least one compound (A) selected from the gro

A body fluid-absorbing article such as, for example, a disposable diaper is provided with at least one absorbent member comprising 50 to 99% by weight of a fibrous material and 50 to 1% by weight of an absorbent polymer, which absorbent member contains at least one compound (A) selected from the group consisting of sulfur-containing reducing agents, antioxidants, and oxidizing agents. By the action of the compound (A), the swelled gel of the absorbent polymer formed in consequence of absorption of body fluid is prevented from being deteriorated or decomposed by aging.

A body fluid-absorbing article comprising at least one absorbent member which forms a swelled gel when a body fluid is absorbed, comprising 50 to 99% by weight of a fibrous material and 50 to 1% by weight of an absorbent polymer, wherein said absorbent polymer is at least one member selected from the group consisting of hydrolyzed starch-acrylonitrile graft polymer, partially neutralized starch-acrylic acid graft polymer, saponified vinyl acetate-acrylic ester copolymer, hydrolyzed acrylonitrile copolymers, cross-linked hydrolyzed acrylonitrile copolymers, hydrolyzed acrylamide copolymers, cross-linked hydrolyzed acrylamide copolymers, partially neutralized polyarcylic acid, cross-linked partially neutralized polyacrylic acid, and isobutylene-maleic anhydride copolymer, said absorbent member containing at least one species compound (A) selected from the group consisting of sulfur-containing reducing agents, antioxidants, and oxidizing agents, wherein said sulfur-containing reducing agent is at least one member selected from the group consisting of thiosulfates, sulfurous acid, sulfites, hydrogen sulfites dithionites, hydrosulfides, and mercaptans, and said compound (A) being present in a physical mixture with said absorbent polymer in an amount capable of preventing the swelled gel of the absorbent polymer from being deteriorated or decomposed with an elapse of time.
