The present invention is directed to an antimicrobial hydrogel-forming absorbent polymer comprising a hydrogel-forming absorbent polymer, and an antimicrobial comprising a 1-hydroxy-2-pyrrolidone derivative represented by formula (I) wherein R1 represents an alkyl group having 1-17 carbon atoms, alkenyl group having 2-17 carbon atoms, cycloalkyl group having 5-8 carbon atoms, bicycloalkyl group having 7-9 carbon atoms, cycloalkyl-alkyl group wherein the alkyl group has 1-4 carbon atoms and the cycloalkyl group may be substituted with an alkyl group having 1-4 carbon atoms, aryl group, aralkyl group with an alkyl group having 1-4 carbon atoms, aryl-alkenyl group with the alkenyl group having 2-4 carbon atoms, aryloxyalkyl or arylmercaptoalkyl group with the alkyl group having 1-4 carbon atoms, benzhydryl group, phenylsulfonylalkyl group with the alkyl group having 1-4 carbon atoms, furylalkenyl group with the furyl or alkenyl group having 2-4 carbon atoms, wherein the above-mentioned aryl residual group may be substituted with an alkyl group having 1-4 carbon atoms, alkoxy group having 1-4 carbon atoms, nitro group, cyano group, or a halogen atom; R2 represents a hydrogen atom, alkyl group having 1-4 carbon atoms, alkenyl group having 2-4 carbon atoms, halogen atom, phenyl group, or benzyl group; and X+ represents an organic base, alkali metal ion, ammonium ion, alkaline earth metal ion, or a divalent to tetravalent cationic ion. The present invention further relates to a process for making such an antimicrobial hydrogel-forming absorbent polymer. The present invention further relates to a disposable absorbent article comprising an antimicrobial hydrogel-forming absorbent polymer.
