Resin composition and film formed from same

A resin composition consisting of:

• a polycarbonate resin (A) containing, as main repeating units, a unit (a-1) represented by the following formula (a-1)
• and a unit (a-2) represented by the following formula (a-2)
• wherein W represents a C1-20 alkylene group or a C6-20 cycloalkylene group, R represents a branched or linear-chain C1-20 alkyl group or a C6-20 cycloalkyl group optionally substituted, and
• m represents an integer of 0 to 10;
• and
• an acrylic resin (B) containing as monomer components, 50 to 99 mol % of methyl methacrylate and 1 to 50 mol % of methyl acrylate,
• wherein the polycarbonate resin (A) and the acrylic resin (B) are in a weight ratio of 50:50 to 90:10,
• wherein the resin composition has a single glass transition temperature, and the glass transition temperature is in the range of 90° C. to 150° C.,
• wherein the polycarbonate resin (A) has a molar ratio (a-1/a-2) of the unit (a-1) to the unit (a-2) of 40/60 to 85/15,
• wherein the polycarbonate (A) has a specific viscosity (ηSP) of 0.3 to 1.5,
• wherein the resin composition is produced by a step consisting of melt mixing the polycarbonate resin (A) and the acrylic resin (B) in a twin-screw extruder, and
• wherein the resin composition has a total light transmittance of 85% or more.
