Abstract (en)

The present invention relates to an artificial leather composed of a dope-dyed polyester fiber, which comprises carbon black in island component of a sea-island composite fiber and polyurethane polymer elastomer during producing an artificial leather. According to the present invention, it is possible to improve the fastness to light and the fastness to rubbing at medium and deeper color, and at the same time, to have a luxuriously high quality and to reduce the amount of dye used in the production of artificial leather.
