成皮革である。[Means for Solving the Problems] The present inventors have conducted intensive studies on non-adhesive polyurethane resin compositions for synthetic leather skin layers and synthetic leathers that have good solvent solubility and good surface slipperiness when made into synthetic leathers. As a result, we have arrived at the present invention. That is, the present invention relates to a non-adhesive polyurethane resin composition for a synthetic leather skin layer comprising a polyurethane resin and an unsaturated fatty acid monoamide having no substituents, and a synthetic leather comprising a base fabric having a coating layer of this composition.

剤溶解性が高くても滑り性の効果が小さい。Among these, oleic acid amide and erucic acid amide are preferred, and erucic acid amide is particularly preferred. When a saturated fatty acid monoamide, a fatty acid monoamide having a substituent, a fatty acid bisamide, a fatty acid, and a fatty acid ester are used instead of the unsaturated fatty acid monoamide according to the present invention, the solvent solubility is low or even if the solvent solubility is high. The effect on slipperiness is small.
