    摘要: The present invention relates to a suede type artificial leather having antifouling property in which a polymeric elastomer is impregnated in a nonwoven fabric formed by three-dimensionally interlacing ultrafine fibers and raising is formed, wherein the polymeric elastomer is a fluorine-containing modified polyurethane, and the fluorine-containing modified polyurethane is a product obtained by a polymerization reaction between a urethane prepolymer having isocyanate groups at terminals, obtained by reacting a diol and a diisocyanate, and a fluorinated carbon compound having hydroxy functional groups at both terminals, and has a weight average molecular weight (Mw) of 500,000 to 800,000. According to the present invention, the suede type artificial leather is prepared by using a fluorine-containing polyurethane elastomer having antifouling property during the preparation of the artificial leather, thus a separate fluorine-based surfactant for an antifouling property does not need and the surface change with the passage of time of the artificial leather caused by using a fluorine-based surfactant does not occur.
