Abstract: Disclosed is a leather-dike sheet including a fiber base material and a colored resin layer laminated on the fiber base material, wherein the colored resin layer includes an intermediate layer and a skin layer laminated on the intermediate layer, wherein the skin layer is a layer containing polyurethane and a black pigment of 3 g/m2 or more, and the intermediate layer is a layer containing polyurethane and a black pigment, and in the L*a*b* color system, a leather-like sheet having a lightness value of L*?30 is used.

Abstract: Disclosed is a grain-finished leather-like sheet including a polyurethane skin film containing a polyether-based polyurethane, wherein the polyurethane skin film contains a quinacridone-based red pigment, and is colored in a red color having an L* value of ?80, an a* value of ?20, and a b* value of ?15 in an L*a*b* color system, and the number of cycles of a flexing endurance test at which cracking occurs in a surface of the polyurethane skin film is 100000 or more, when the flexing endurance test is performed on the grain-finished leather-like sheet under an environment of 20° C. using a flexometer after the grain-finished leather-like sheet has been irradiated with carbon arc at a black panel temperature of 63° C. for 100 hours with an irradiance of 500±50 W/m2, using ultraviolet carbon arc lamp light compliant with JIS B 7751.

Abstract: Disclosed is a grain-finished leather-like sheet including: a fiber base material; a polyurethane intermediate layer stacked on the fiber base material; and a polyurethane skin film stacked directly on the polyurethane intermediate layer or via another polyurethane layer, wherein the polyurethane skin film contains a silicone-modified polyurethane, and the grain-finished leather-like sheet has an uneven surface whose skewness (Ssk), kurtosis (Sku), and maximum height (Sz) of surface roughness in accordance with ISO 25178 respectively satisfy ?0.4?Ssk??0.2, 3?Sku?4, 60 ?m?Sz?150 ?m.

Abstract: Disclosed is a grain-finished leather-like sheet including: a fiber base material; and a polyurethane skin film stacked, as a surface layer, directly on the fiber base material or via another polyurethane layer, wherein the polyurethane skin film contains at least one of a diketopyrrolopyrrole-based red pigment and an ?-type phthalocyanine-based blue pigment, the grain-finished leather-like sheet further includes a clear polyurethane film layer coating the polyurethane skin film, and the grain-finished leather-like sheet has a grade of color difference, determined using a Grey scale for assessing staining, of 4-5 or more, when 0.03 g of oleic acid is added dropwise to a surface of the clear polyurethane film layer, and thereafter a white cotton fabric is reciprocated 100 times on the surface, using a crockmeter.
