Title:
INFRARED LIGHT-PERMEABLE POLYESTER RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/133056
Kind Code:
A1
Abstract:
The invention is a polyester resin composition that satisfies requirements (1) and (2) below and contains 0.1-1 part by mass of a C3-40 organoarboxylic acid alkali metal salt (B) and 0.05-3 parts by mass of a polycarbodiimide compound (C) per 100 parts by mass of a polyester resin (A), wherein the polyester resin composition has excellent infrared light permeability as well as good heat resistance and low gassing, and is suitable for use as a design member (in particular, a lamp member). (1) The average value of the transmittance at a wavelength of 800-1100 nm of a 2 mm thick plate obtained from this polyester resin composition is 20 to 75%. (2) The heat deformation temperature (0.45 MPa) is 150°C or higher.
