Abstract
A translucent resin composition comprises a transparent resin, and a natural fiber having a birefringence Δn of 0.013 to 0.15 and an average particle size of 2 to 100 μm. The translucent resin composition contains 1 to 20 parts by mass of natural fiber with respect to 100 parts by mass of transparent resin. The translucent resin composition is used for depolarization. The natural fiber is an animal fiber.

A translucent resin composition comprising:
- a transparent resin;
- and
- a natural fiber having a birefringence Δn of 0.013 to 0.15 and an average particle size of 2 to 100 μm,
- wherein the translucent resin composition contains 1 to 20 parts by mass of natural fiber with respect to 100 parts by mass of transparent resin,
- wherein the translucent resin composition is used for depolarization,
- wherein the natural fiber is an animal fiber,
- wherein the average particle size is a particle diameter (D50:
- median diameter) corresponding to 50% in the volume-based cumulative particle size distribution measured by the laser diffraction method, and
- wherein the birefringence Δn is determined based on a maximum retardation R, which corresponds to an interference color on a microregion of particle of the natural fiber observed in a crossed Nicol state using a polarizing microscope, and Δn=R/t (where t is the average particle size of the natural fiber).
