ARTIFICIAL LEATHER

To provide an artificial leather having a low environmental load resulting from no use of organic solvent in production process, excellent in clarity of embossed patterns.SOLUTION: An artificial leather comprises a nonwoven fabric made of ultra fine fiber having an average single fiber diameter of 0.3 μm or more and 7 μm or less and water dispersion type polyurethane. In pulse NMR measurement (solid echo method, proton observation, measurement temperature: 50°C) of the artificial leather, when the free induction attenuation decay (FID) of signals is fitted to two components including a component S (Gauss component) and a component L (Lorentz component), the component L has a spin-spin relaxation time Tl of 500 μ seconds or more and 800 μ seconds or less, and the component L has a fraction Cl of 25% or more and less than 55%.SELECTED DRAWING: None 【課題】製造工程に有機溶剤を使用しないため環境負荷が低く、かつ、エンボス柄の明瞭性に優れる人工皮革の提供。【解決手段】平均単繊維直径０．３μｍ以上７μｍ以下の極細繊維からなる不織布と水分散型ポリウレタンからなる人工皮革であって、該人工皮革はパルスＮＭＲ測定（Ｓｏｌｉｄ Ｅｃｈｏ法、プロトン観測、測定温度５０℃）における自由誘導減衰信号（ＦＩＤ）をＳ成分（ガウス成分）、Ｌ成分（ローレンツ成分）の２成分についてフィッティングした場合、Ｌ成分のスピン－スピン緩和時間Ｔｌが５００μ秒以上８００μ秒以下であり、Ｌ成分の分率Ｃｌが２５％以上５５％未満であることを特徴とする人工皮革。【選択図】なし
