Abstract:
An oil tone artificial leather sheet, comprising:a napped sheet comprising a non-woven fabric of microfine fibers and a polyurethane in the non-woven fabric, wherein raised fibers comprising the microfine fibers are present in at least a portion of at least one surface of the sheet and form the nap surface; and a blend of an oily substance having a viscosity of 50 to 10,000 mPaÂ·s at 30Â° C. and a supporting polymer on at least a portion of the nap surface of the napped sheet, wherein the supporting polymer is (a) a block copolymer comprising an ethylene polymer or ethylene polymer block having hydrocarbon groups with 1-8 carbon atoms in side chains, and 5-60% of units having side chains relative to the ethylene unit forming the main chain, or (b) a block copolymer comprising a polymer block A comprising a vinyl aromatic compound and a polymer block B comprising a conjugated diene, or a hydrogenation product thereof.
