RESIN COMPOSITION SUITABLE FOR LASER WELDING APPLICATION HAVING RESIN AND LASER BEAM TRANSMITTING COLORANT, AND HAVING TRANSMISSION RATE RATIO (T BLACK RESIN FOR LASER TRANSMISSION/T NATURAL RESIN) OF 0.5-1.2

摘要

PPROBLEM TO BE SOLVED: To provide a novel resin composition that is suitable for laser welding applications. PSOLUTION: The resin composition suitable for laser welding applications comprising a resin and a laser beam transmitting colorant is provided. The resin composition suitable for laser welding applications has a transmission rate ratio (TSBblack resin for laser transmission/SB/TSBnatural resin/SB) of 0.5-1.2 wherein the laser transmission rate containing a laser beam transmitting black colorant for laser beams with wavelength at 940 nm is TSBblack resin for laser transmission/SBand the laser transmission rate of the resin itself for laser beams with wavelength at 940 nm is TSBnatural resin/SB. The laser beam transmitting black colorant comprises an anthraquinone dye or a monoazo complex dye. PCOPYRIGHT: (C)2008,JPO&INPIT
