To join a colored resin substrate with a hard coat layer and a molded article base body made of various materials by irradiation with laser light with a good joint strength.SOLUTION: A colored resin substrate 1 with a hard coat layer used is a colored resin substrate 1 with a hard coat layer having a colored hard coat layer 13 laminated on one surface of a transparent resin substrate 11. A method for manufacturing a joined body of a colored resin substrate with a hard coat layer comprises: a lamination step of laminating the colored resin substrate 1 with a hard coat layer on a molded article base body 2, with the colored hard coat layer 13 facing the surface of the base body, to obtain a laminate for joining; and a laser beam irradiation step of irradiating the laminate for joining with a laser beam so as to directly join the colored hard coat layer 13 to the surface of the molded article base body 2 or to join via a resin 3 for joining.SELECTED DRAWING: Figure 3
【課題】ハードコート層付き有色樹脂基材と、各種材料からなる成型品基体を、レーザー光の照射によって、良好な接合強度で接合すること。【解決手段】ハードコート層付き有色樹脂基材1として、透明樹脂基材11の一方の面に、有色ハードコート層13が積層されているハードコート層付き有色樹脂基材1を用い、ハードコート層付き有色樹脂基材1を、有色ハードコート層13を成型品基体2の表面の側に向けて、積層することにより接合用積層体を得る積層工程と、接合用積層体にレーザー光を照射することにより、有色ハードコート層13を、成型品基体2の表面に、直接接合するか、或いは、接合用樹脂3を介して接合する、レーザー光照射工程と、を含んでなる、ハードコート層付き有色樹脂基材接合体の製造方法とする。【選択図】図3
