摘要
PROBLEM TO BE SOLVED: To provide a water-based polyurethane resin emulsion composition that is good in dispersibility during production, and is used in a surface treatment agent for artificial leather and synthetic leather having excellent flexibility, abrasion resistance, resistance to oleic acid, and water resistance.SOLUTION: By introducing a polyisocyanate at least containing an allophanate-modified diisocyanate and an organic diisocyanate, and a predetermined amount of polycarbonate diol obtained from 3-methyl-1,5-pentane-diol as a glycol, and by controlling the molecular weight of the urethane prepolymer, a water-based polyurethane resin emulsion composition that is good in dispersibility during production, and that can bring about a surface treatment layer for artificial leather and synthetic leather having excellent flexibility, abrasion resistance, resistance to oleic acid, and water resistance, is obtained.SELECTED DRAWING: None
