Title:
WATER-ABSORBING RESIN COMPOSITION, ABSORBENT AND ABSORBENT ARTICLE EACH INCLUDING SAME, AND METHOD FOR PRODUCING WATER-ABSORBING RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/276930
Kind Code:
A1
Abstract:
This water-absorbing resin composition comprises: a crosslinked polymer (A) comprising, as essential constituent units, a water-soluble vinyl monomer (a1) and/or a vinyl monomer (a2), which becomes a water-soluble vinyl monomer (a1) upon hydrolysis, and a crosslinking agent (b); and one or more compounds (B) selected from the group consisting of compounds represented by general formula (1) and compounds represented by general formula (2) and/or one or more salts of the compounds (B). The crosslinking agent (b) is a polyvalent (meth)allyl compound. The water-absorbing resin composition can be inhibited from changing in tint and in soluble-component-content through long-term storage in high-temperature high-humidity environments. The present invention can further provide an absorbent and an absorbent article each including the water-absorbing resin composition and a method for producing the water-absorbing resin composition.
