<p>A leather-like sheet base composed of a non-woven fabric in which ultrafine fibers (A) of 0.5 dt or less three-dimensionally interlock with each other and an elastic polymer (B) filled in the interlocking space, wherein the ultrafine fibers (A) are made of a polyester having an organic phosphorus comonomer and the elastic polymer (B) contains a metal hydroxide or an organic phosphorus comonomer. This leather-like sheet base or artificial leathers obtained by using the same are free from halogen and have a high flame retardancy and a soft texture. Thus, they are appropriately usable in the field of interior decoration (in particular, vehicle seats etc.) with a need for flame retardancy.</p> |
