摘要
An artificial leather having a suede appearance and colors within the grey-black range and high color fastness comprising a microfibrous component and an elastomeric matrix; the microfibrous component consisting of polyester microfibers having a count of 0.01 to 0.50 dtex; the elastomeric matrix consisting of polyurethane consisting of soft and hard segments; the ratio between the elastomeric matrix and the microfibrous component ranging from 20/80 and 50/50 by mass; the microfibrous component containing carbon black pigment in a percentage of 0.05 to 2.00% by mass; the elastomeric matrix containing carbon black pigment in a percentage of 0 to 10% by weight; the carbon black always having an average dimension smaller than 0.4 microns. 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. The total content of carbon black is between 0.025 and 6% by weight.
