Laser welded material of laser beam permeable member containing alkaline earth metal salt of anthraquinone acid dye

摘要

A laser-welded article comprises:
a laser-transmissible workpiece made from a laser-transmissible colored resin composition including at least a thermoplastic resin and an alkaline earth metal salt of an anthraquinone-type acidic dye represented by the following chemical formulae (1) and/or (2) and a laser-absorptive workpiece putting the laser-transmissible workpiece together,
wherein the workpieces are welded at the put position thereof by irradiated laser towards the laser-transmissible workpiece that transmits therethrough and is absorbed into the laser-absorptive workpiece.
