In a method for improving bonding strength between a first resin article and a second resin article, the method comprises using a compatibilizer for both a first thermoplastic resin and a second thermoplastic resin, wherein the first resin article is formed from a first resin composition comprising a first thermoplastic resin, and the second resin article is formed from a second thermoplastic resin or a second resin composition comprising a second thermoplastic resin, and at least the first resin composition out of the first and the second resin compositions comprises the compatibilizer, wherein the first and the second resin articles are welded to each other by laser irradiation to form a composite article. |
