Abstract

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.

Description

technical field [0001] The present invention relates to a laser welded body prepared from a laser penetrating member and a laser absorbing member and a laser welding method for the laser welded body. It is prepared from a laser penetrating colored resin composition of an alkaline earth metal salt. Background technique [0002] It is well known to join members made of thermoplastic synthetic resin materials by laser welding. [0003] Such laser welding can be performed, for example, as follows. As shown in Figure 1, a laser-transmitting member is used on one member, and a laser-absorbing member is used on the other member, and then the two are butted. When the laser-absorbing member is irradiated with laser light from one side of the laser-transmitting member, the laser light transmitted by the laser-transmitting member is absorbed in the laser-absorbing member, thereby generating heat. Through this heat generation, the laser-absorbing member melts centering on the laser-a...
