PROBLEM TO BE SOLVED: To provide a laminated sheet roll in which appearance defects such as gauge band, wrinkle, slack or irregular winding are inhibited to exert favorable printing characteristics, and to provide a method for production thereof. SOLUTION: The method for production of a laminated sheet roll includes the steps of: applying a mixed solution comprising a resin composition (A) and a solvent (S) onto an acrylic resin substrate sheet (B); heating and drying the acrylic resin substrate sheet (B) for volatilizing the solvent (S) to form the layer of the resin composition (A) on the sheet (B); and winding a laminated sheet including the resin composition (A) and the sheet (B). The elongation percentage (L) at heat drying of the acrylic resin substrate sheet (B) is≥0.001% but≤0.5%, and the tension (F2) per unit width of the laminated sheet when winded is≥60 N/m but≤170 N/m.
