摘要
PROBLEM TO BE SOLVED: To provide a release sheet which is used for the manufacture of a synthetic leather and can impart a matte finish or a peach skin finish appearance and feel to the surface of a synthetic leather and further, is used for the repeated manufacture of a synthetic leather of a varying color without color migration, and a synthetic leather with a high matte finish or a peach skin finish surface manufactured using the release sheet.;SOLUTION: The release sheet 10 is constituted of a releasable resin layer 2 with fine irregularities formed at least on the surface, formed on a base sheet 1 and a releasable transparent synthetic resin applied in such a way that it remains at the bottoms of the recessed parts of the fine irregularities. When especially the peach skin finish surface is formed, the fine irregularities preferably show that the arithmetic mean roughness Ra is 0.5 to 15 μm and the average interval Sn is 0.5 to 10 μm and the average gradient θa is 45 to 90°. Thus it is possible to use the release paper 10 safely and repeatedly for the manufacture of the synthetic leather of a varying color with a matte finish or a peach skin finish surface.;COPYRIGHT: (C)2003,JPO
