평균 단섬도가 0.5데니어 이하인 극세 폴리아미드 섬유로 이루어진 교락 부직포와 폴리우레탄을 주체로 하는 중합체로 이루어진 스웨드 느낌의 인공 피혁에 있어서, 스웨드 느낌의 인공 피혁의 적어도 표면에 황화 염료, 건염 염료 및 황화 건염 염료로부터 선택된 하나 이상의 염료와 2,2',4,4'-테트라하이드록시벤조페논을 존재시킨다. 이로써, 내광성, 세탁견뢰도 및 드라이클리닝 견뢰도가 대단히 우수한 스웨드 느낌의 인공 피혁을 수득한다. In a suede-like artificial leather comprising an entangled nonwoven fabric composed of microfine polyamide fibers having an average single fineness of 0.5 denier or smaller and a polymer composed mainly of polyurethane, at least one dye selected from the group consisting of sulfur dyes, vat dyes and sulfur vat dyes and 2,2',4,4'-tetrahydroxy benzophenone are allowed to exist at least on the surface of the suede-like artificial leather. This makes it possible to provide a suede-like artificial leather having excellent color resistance to light and color fastness to washing and dry-cleaning.
