Abstract

L'objectif de la présente invention est de fournir une composition de traitement de surface qui, en étant appliquée à la surface d'un objet à traiter, peut facilement conférer des propriétés d'absorption de l'eau et des propriétés de répulsion de l'eau à la surface. Cette composition de traitement de surface comprend (A) un polymère absorbant l'eau, (B) un composant huileux, (C) de l'eau, et (D) un émulsifiant ou un agent dispersant. De préférence, l'eau et le polymère absorbant l'eau dans la composition de traitement de surface sont dispersés dans la phase de composant huileux par l'émulsifiant ou l'agent dispersant. Il est également préférable que la composition de traitement de surface contienne (A) le polymère absorbant l'eau en une quantité comprise entre 5 % en masse et 70 % en masse inclus, (B) le composant huileux en une quantité comprise entre 10 % en masse et 60 % en masse inclus, (C) l'eau en une quantité comprise entre 10 % en masse et 70 % en masse inclus, et (D) l'émulsifiant ou l'agent dispersant en une quantité comprise entre 0,1 % en masse et 20 % en masse inclus.
