Definitions
- the present invention relates to a laser-transparent colored thermoplastic resin composition containing an anthrapyridone-based acid dye, and a laser-transparent colored resin composition.
- the present invention relates to a laser welding method using a thermoplastic resin composition.
- BACKGROUND ART Laser welding of synthetic resin materials can be performed, for example, as follows. As shown in Fig. 1, a laser beam transmitting material is used for one member, and a laser light absorbing material is used for the other member, and the two members are brought into contact. When a laser beam is irradiated from the side of the laser light transmitting material toward the laser light absorbing material, one laser beam transmitted through the laser light transmitting material is absorbed by the laser light absorbing material and generates heat.
- the laser light absorbing material melts around the portion that absorbed the laser light, and the laser light transmitting material also melted to fuse both resins. After cooling, sufficient welding strength was obtained.
- the laser light transmitting material and the laser light absorbing material are firmly joined.
- the advantages of laser welding are that it can be welded without contacting the laser light-generating part with the spot where it is to be welded. No problem, welding of fine parts and structures is possible, high reproducibility, high airtightness can be maintained, high welding strength, the welding part is hard to see, dust, etc. And the like.
- Japanese Patent Application Laid-Open No. H11-170371 discloses an opaque member made of a thermoplastic synthetic resin that absorbs laser light and a colorless transparent member made of a thermoplastic synthetic resin that transmits laser light.
- a laser welding method including a step of irradiating a laser beam so that a focus is brought into contact with a portion where the laser beam contacts is described.
- the welded portion when viewed from the colorless and transparent member side, the welded portion has a different color and smoothness from the unwelded portion, and thus has a problem that the appearance is poor.

- a laser beam 14 from a 60 W output diode laser [wavelength: 940 nm continuous] (manufactured by Fine Device Co., Ltd.) was applied to the overlapped portion from above in the figure of the test piece 10 by changing the scanning speed. Scanning was performed in the direction (perpendicular to the plane in Fig. 1).
- the laser light-absorbing test piece 12 If the laser light is transmitted through the test piece 10 and absorbed by the laser light-absorbing test piece 12, the laser light-absorbing test piece 12 generates heat, and this heat causes the laser to be focused on the portion that absorbed the laser light.
- the light-absorbing test piece 12 is melted, and the test piece 10 is also melted to fuse both resins, and the two are joined by cooling.
- Reference numeral 16 in FIG. 2 denotes a welded portion.
- the welded material obtained in (4) was subjected to a tensile tester (AG-50 kNE manufactured by Shimadzu Corporation) on the side of the test piece 10 and a laser light-absorbing test piece according to JI SK71 13-1955.
- a tensile test was performed on the 12 side in the vertical direction (left-right direction in FIG. 1) at a test speed of l OmmZmin to measure the tensile welding strength.
