PROBLEM TO BE SOLVED: To provide an absorbent resin particle composition that can produce an absorbent article free from problems such as rash.SOLUTION: This absorbent resin particle composition comprises an absorbent resin particle (B1) and an absorbent resin particle (B2), wherein the (B1) and (B2) are absorbent resin particles including a crosslinked polymer comprising a water-soluble vinyl monomer and/or hydrolyzable vinyl monomer and a crosslinking agent as essential constituent units the following swelling time ratio (t2/t1) of (B1) and (B2) is each 3-20 the time (t1) until the swelled volume of (B1) reaches 5 mL is 10s or more and less than 30 s the time (t1) until the swelled volume of (B2) reaches 5 mL is 30 s or more and 120 s or less. The swelling time ratio (t2/t1) is a ratio of the time (t1) until the swelled volume reaches 5 mL and the time (t2) until the swelled volume reaches 40 mL, in a measuring method of the swelled volume in the physiological saline per 1 g of absorbent resin particles.COPYRIGHT: (C)2012,JPO&INPIT【課題】カブレ等の問題を生じない吸収性物品を製造できる吸収性樹脂粒子組成物を提供する。【解決手段】吸収性樹脂粒子(B1)と吸収性樹脂粒子(B2)とを含んでなる吸収性樹脂粒子組成物であって、(B1)及び(B2)が水溶性ビニルモノマー及び/又は加水分解性ビニルモノマー、並びに架橋剤を必須構成単位とする架橋重合体を含んでなる吸収性樹脂粒子であり、(B1)及び(B2)の下記膨潤時間比(t2/t1)が各々3~20であり、(B1)の膨潤容積が5mlに達するまでの時間(t1)が10秒以上30秒未満であり、(B2)の膨潤容積が5mlに達するまでの時間(t1)が30秒以上120秒以下である吸収性樹脂粒子組成物。膨潤時間比(t2/t1):吸収性樹脂粒子1g当たりの生理食塩水に対する膨潤容積測定法において、膨潤容積が5mlに達するまでの時間(t1)と、膨潤容積が40mlに達するまでの時間(t2)の比【選択図】図1
