Polyurethane resin composition, cured product, artificial leather, synthetic leather, and surface treatment agent for leather |
| abstract |
The present invention relates to a polyurethane resin composition that contains an isocyanate group-terminated urethane prepolymer (E) and a neutralizer (F). The isocyanate group-terminated urethane prepolymer (E) contains a reaction product of a polyol (A) that contains a polycarbonate polyol (B) which has an average number of hydroxyl functional groups of more than 2, an organic acid (C), and polyisocyanate (D). In the polyurethane resin composition, the total content of urea groups is 0.01-0.80 mmol/g relative to the total sum of the mass of the isocyanate group-terminated urethane prepolymer (E) and the mass of a chain extender (G), and the deemed average number of functional groups of the polycarbonate polyol (B) is 2.0-3.90. |
