    Abstract: An optical member and a method for producing this optical member are provided. The optical member is composed of an injection molded article. The injection molded article includes a glutarimide resin that contains a glutarimide unit having an imidocarbonyl group provided by the imidization of a carbonyl group deriving from (meth)acrylate ester monomer, a repeat unit deriving from (meth)acrylate ester monomer, and a repeat unit deriving from aromatic vinyl monomer. The glutarimide resin has an orientation birefringence of −0.5×10−3 to 0.5×10−3, a photoelastic constant of −3.0×10−12 Pa−1 to 3.0×10−12 Pa−1, and a glass transition temperature of at least 125° C. The average value of the phase difference of the optical member is not more than 20 nm.

    Abstract: A masterbatch (C) containing thermally expandable microcapsules (A) and a carrier resin composition (B) is provided. The carrier resin composition (B) contains a carrier resin (B1) and a plasticizer (B2), the carrier resin (B1) being an acrylic resin having a weight average molecular weight of 8,000 or more and 350,000 or less, and the plasticizer (B2) being an acrylic plasticizer having a weight average molecular weight of 1,000 or more and 20,000 or less. The carrier resin composition (B) is substantially compatible with a polycarbonate resin and has a shear viscosity of 1.0 Pa·s or more and 1.5×106 Pa·s or less at 80° C. The occurrence of whitening is suppressed and a good appearance can be obtained in an injection molded foam made with the masterbatch. A polycarbonate resin composition, an injection molded foam, and a method for producing an injection molded foam are provided.
