Zusammenfassung:	섬유 기재와, 섬유 기재의 일면에 접착된 폴리우레탄 표피층과, 섬유 기재와 상기 폴리우레탄 표피층을 접착하는 폴리우레탄 접착층을 구비하는 은부 피혁형 시트로서, 폴리우레탄 접착층은, 수계 폴리우레탄을 주체로서 함유하고, 황산염 또는 알킬황산에스테르염을, 황 원자 환산으로 0.01 ∼ 0.45 질량％ 함유하고, 또한 BCG (브로모크레졸 그린) 액에 의한 정색이 pH 4.8 이하 상당인 은부 피혁형 시트. Disclosed is a grain-finished leather-like sheet including: a fiber base material; a polyurethane skin layer bonded to one surface of the fiber base material; and a polyurethane adhesion layer that bonds the fiber base material and the polyurethane skin layer to each other, wherein the polyurethane adhesion layer includes an aqueous polyurethane as a main component, contains 0.01 to 0.45 mass%, in sulfur atoms content, of a sulfate or an alkyl sulfate, and exhibits coloration equivalent to pH 4.8 or less that is caused by a BCG (bromocresol green) solution.
