A methacrylic resin composition comprising: a multilayered graft copolymer obtained by polymerizing monomers consisting mainly of an alkyl methacrylate such as methyl methacrylate in the presence of a chain transfer agent to form an innermost layer made of a crosslinked methacrylic polymer, subsequently polymerizing at least one monomer consisting mainly of an alkyl acrylate such as butyl acrylate in the presence of the innermost-layer polymer to form an interlayer, and then polymerizing at least one monomer consisting mainly of an alkyl methacrylate such as methyl methacrylate to form an outermost layer on the interlayer; and a methacrylic resin. The composition is excellent in transparency, appearance, weatherability, gloss, impact resistance, and processability.
