WATER ABSORBING AGENT AND PRODUCTION METHOD THEREOF

摘要

According to a water absorbing agent of the present invention and a method of the present invention for producing the water absorbing agent, (i) water absorbent resin particles having an internal cross-linked structure obtained by polymerizing a water-soluble unsaturated monomer, (ii) organic acid (salt), and (iii) water-soluble multivalent metal salt are mixed, so that it is possible to provide a water absorbing agent which suppresses permeation of metal components into the water absorbent resin particles and enables the metal components to evenly adhere to an entire surface of the water absorbent resin in a dot manner.
