A polycarbonate resin film which has an average thickness of 10 to 150 &#x3bc;m, a thickness nonuniformity of 2% or less, a retardation R(589) in the plane of the film measured at a wavelength of 589 nm of 12 nm or less, a retardation Rth(589) in the thickness direction of the film measured at a wavelength of 589 nm of 35 nm or less and is used for optical purposes.

Polycarbonate resin film and manufacturing process thereof

A resin composition, and molded articles thereof, where the resin composition simultaneously satisfies resistances, such as heat and environmental resistance, and moldability at high levels, and has excellent optical properties, such as high refractivity and low birefringence. The resin composition contains a polyester resin formed from a dicarboxylic acid component and a diol component (a) and a polycarbonate resin formed from a carbonate-forming component and a diol component (b), the diol component (a) containing a specific fluorene-containing compound and the diol component (b) containing a specific fluorene-containing compound.

Resin composition and molded articles thereof

The present invention discloses an infrared absorption filter which enables a coloring matter having infrared absorptivity to be contained or dispersed uniformly in a high concentration and has excellent durability, and an infrared absorption panel comprising this infrared absorption filter. The infrared absorption filter comprises a polycarbonate resin which contains 20 to 100 mol % of a recurring unit having a fluorene skeleton represented by the formula (1) and 0 to 80 mol % of a recurring unit represented by the formula (2), and a coloring matter having infrared absorptivity.
