PROBLEM TO BE SOLVED: To obtain a water-absorbing resin for repetitive use which has a high water-absorbing rate and a high water-releasing rate on drying, is durable to cleaning and to drying in the sun and with dryers and allows repetitive use. SOLUTION: The manufacturing process of the water-absorbing resin comprises reacting an alkali metal hydroxide with a copolymer of at least one kind of monomer selected from the group consisting ofα-olefins and vinyl compounds and maleic anhydride or a maleate and subjecting 100 pts.wt. of the reaction product to crosslinking reaction with 5-20 pts.wt. of a multivalent amine compound.
