Abstract

Se proporcionan lo siguiente: una resina absorbente al agua en la cual, en la formación de un material absorbente que forma un artículo absorbente, la dispersión es satisfactoria aún en un estado de absorción de humedad, que previene la ocurrencia de problemas al momento de la fabricación del artículo absorbente y que permite la fabricación eficiente; y un artículo absorbente usando un material absorbente que contiene la resina absorbente al agua. La resina absorbente al agua de acuerdo con la presente invención se obtiene al polimerizar un monómero no saturado etilénicamente soluble en agua y realizar la post-reticulación sobre eso con un agente de post-reticulación, y la resina absorbente al agua satisface los requerimientos a continuación: (A) índice amarillo es 5.0 o menos; y (B) fuerza de gel es 1800 Pa o menos.
