Zusammenfassung:	A high-quality artificial leather is described, having a suede appearance and colors within the grey-black range, the light fastness of the colors according to the method SAE J 1885 225.6 KJ/m2 being higher than or equal to 4; the lightfastness of the colors according to the method SAE J 1885 488.8 KJ/m2 being not lower than 3; said artificial leather having a tassel on the surface of the leather itself. The average length of the tassel is between 200 and 500 microns. The soft segments consist of at least one polycarbonate diol selected from polyalkylene carbonate diols and at least one polyester diol; the hard segments consist of urethane groups deriving from the reaction between free isocyanate groups and water; and the total content of carbon black is between 0.025 and 6% by weight.
