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 mPa·s at 30° 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.
