摘要： A process for producing a methacrylic resin molded article having a surface fine structure with a high aspect ratio. The method includes injecting a composition into a cell or cavity provided with a negative pattern corresponding to the surface fine structure, and solidifying the composition in the cell or cavity by polymerization. The composition contains components A, B, and C. A: an unsaturated monomer mixture, which includes 20 to 90% by weight of an unsaturated monomer including methylmethacrylate as a major component, and 10 to 80% by weight of an unsaturated monomer having at least two polymerizable double bonds in one molecule; B: a polymer of an unsaturated monomer including methylmethacrylate as a major component, which polymer includes 20 to 100% by weight of partially crosslinked polymer particles and 0 to 80% by weight of non-crosslinked polymer particles; and C: a polymerization initiator.
