Abstract
PURPOSE: To improve water absorbing capacity of an anionic water absorbable resin in an ionic aqueous solution by using three components of a soluble aluminum salt, a neutralizing agent and an anionic insoluble water absorbing resin as essential components of a water absorbing agent.
CONSTITUTION: A soluble aluminum salt such as aluminum sulfate or aluminum nitrate, a neutralizing agent such as potassium dihydrogen phosphate or the like and an anionic insoluble water absorbing resin such as a polyacrylic acid type insoluble resin or the like are used three essential components to prepare a water absorbing agent. If said water absorbing agent is used in an ionic aqueous solution, salt resistance of the anionic water absorbable resin can be improved.
