摘要：
Thermoplastic resin compositions suitable for laser welding are disclosed, which include a mixture of neutral anthraquinone blue dye with other red dye to absorb visible light with wavelength less than 700 nm and transmit a laser beam with wavelength at 800 nm to 1200 nm and to enhance weldability.
