PROBLEM TO BE SOLVED: To provide a siloxane-based antistatic agent that has an improved water resistance, does not reduce antistatic performance even in a low humidity environment, and has a stable antistatic performance over time, and to provide an article including the siloxane-based antistatic agent.SOLUTION: A liquid antistatic agent composition comprises: a hydrolysis polycondensate of alkoxysilane that is obtained by hydrolyzing a mixture of a tetraalkoxysilane and/or an oligomer thereof and phenyl alkoxysilane and/or an oligomer thereof and performing polycondensation reaction, and has siloxane bonds (Si-O-Si) as a skelton; polystyrene sulfonic acid; and a solvent where the hydrolysis polycondensate of alkoxysilane and the polystyrene sulfonic acid are dissolved. Phenyl groups of the hydrolysis polycondensate of alkoxysilane and phenyl groups of the polystyrene sulfonic acid constitute a layered structure by - interaction. 【課題】耐水性が改良され、低湿度環境下でも帯電防止性能が低下せず、経時的に帯電防止性が安定な、シロキサン系帯電防止剤と、それを備えた物品を提供する。【解決手段】テトラアルコキシシラン及び／又はそのオリゴマーと、フェニルアルコキシシラン及び／又はそのオリゴマーとの混合物を加水分解し、さら重縮合反応させて得たものであって、シロキサン結合(Si-O-Si)を骨格として有するアルコキシシラン加水分解重縮合物と、ポリスチレンスルホン酸と、前記アルコキシシラン加水分解重縮合物及び前記ポリスチレンスルホン酸を溶解してなる溶媒と、を含んでなり、前記アルコキシシラン加水分解重縮合物のフェニル基と前記ポリスチレンスルホン酸のフェニル基とが ・ 相互作用により積層構造を構成していることを特徴とする液状帯電防止剤組成物。【選択図】なし
