Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing acrylic leather having excellent processability of leather itself, no bleedout and no problem of emission of hydro gen chloride on incineration. SOLUTION: This acrylic leather is obtained by coating a release sheet with a plastisol consisting essentiallly of acrylic resin fine particle of core/shell structure and a phthalic acid ester-based plasticizer, after the application, heating and solidifying the plastisol, to form an acrylic resin layer and laminating a fibrous substrate or a porous substrate to the acrylic resin layer. The core part of the acrylic resin fine particle is constituted of a resin of a monomer unit selected from ethyl methacrylate, n-butyl methacrylate, isobutyl methacrylate, t-butyl methacrylate, cyclohexyl methacrylate and ethylhexyl methacrylate. The shell part of the acrylic resin fine particle is constituted of a resin of a monomer unit selected from methyl methacrylate, benzyl methacrylate and styrene.
