A laser-welded article comprises:
a laser-transmissible workpiece made from a laser-transmissible colored resin composition including a resin and an alkaline earth metal salt of an anthrapyridone-type acidic dye represented by the following chemical formula
[in the chemical formula,
R 7 is allowed to be the group presented by chemical formula (2)
and at least one of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , and R 10 is SO 3 M 1/2 that M is an alkaline earth metal]
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. |
