Abstract: A polyetherimide composition includes a polyetherimide having a percent transmission of 75% to 85% at 500 nanometers as determined according to ASTM D1003 at a thickness of 1.6 mm. The composition further includes a colorant. A molded sample of the polyetherimide composition can have a percent transmission of greater than 40% at a thickness of 1.6 millimeters and a percent transmission of greater than 15% at a thickness of 3.2 millimeters, each at a wavelength of 450 nanometers and determined according to ASTM D 1003. Methods of the manufacture of the polyetherimide composition and injection molded articles prepared therefrom are also disclosed.
