Provided is a dope used when a film containing an acrylic-based resin and a core-shell type graft copolymer is made by a solution casting method, in which turbidity is less likely to occur despite the use of a core-shell type graft copolymer having a core layer with a large particle diameter. A dope for producing a film by a solution casting method contains a thermoplastic acrylic-based resin, a graft copolymer, and a solvent. In this dope, the graft copolymer has a core layer and a shell layer, the core layer has an average particle diameter of 125 to 400 nm, the graft copolymer has a degree of swelling by methyl ethyl ketone of 3.5 or more, and the solvent has a hydrogen bonding term δH in a Hansen solubility parameter of 6.0 or more and 8.0 or less.
