Abstract:
A composition includes specific amounts of an amorphous polycarbonate, a partially crystalline polyester, and an ultraviolet absorbing agent comprising a hydroxyaryl group and a hydrogen-bond accepting group. The ultraviolet absorbing agent has a lambda-max less than 400 nanometers. The composition excludes white pigments, and colorants having a lambda-max of 400 to 700 nanometers. The composition is useful for forming a near infrared laser-transmissive part in a laser welded article that further includes a near infrared laser-absorbing part.
