| description | Provided is artificial leather which does not use organic solvents during the production process and thus has a low environmental impact, and which has no formation of wrinkles during three-dimensional molding. The artificial leather comprises a nonwoven fabric made of ultrafine fibers having a mean single fiber diameter of 0.3 µm to 7 µm, and water-dispersible polyurethane, wherein when the free induction decay (FID) signal in pulse NMR (solid echo method, proton observation, measuring temperature: 50°C) is fitted to two components: the S component (Gaussian component) and L component (Lorentz component), the spin-spin relaxation time Tl of the L component is 500 µsec to 800 µsec and the L component fraction Cl is 55% to 75%. |
