A method for the surface treatment of an absorbent resin is proposed which notably improves the absorption capacity of the absorbent resin under pressure without impairing safety and hydroscopic flowability. The method comprises adding an organic carboxylic ester of a polyhydric alcohol to the absorbent resin and then heat-treating the resultant mixture.
