Abstract

　本発明は、優れた吸水特性（吸水倍率向上、水可溶分および残存モノマーの低減）と粒子表面色の白度向上という二つの特性の両立を実現することを目的としている。この目的にために、本発明の粒子状吸水剤は、ポリアクリル酸（塩）を主成分とする粒子状吸水剤であって、粒子のハンターＬａｂ表面色系におけるｂ値が－５～１０であり、下記式１及び３ 式１；ＧＥＸ＝（ＧＶｓ＋１７）／Ｌｎ（水可溶分量） 式３；ＣＰＩ＝（ＧＥＸ／残存モノマー量）×１００ （ＧＶｓ：無加圧下吸収倍率，Ｌｎ（水可溶分量）：水可溶分量の自然対数） により規定される架橋体特性指数（ＣＰＩ）が１～１００であることを特徴としている。
