A variety of molded bodies having high weatherability, impact resistance, designability, and the like, and a polyorganosiloxane latex and a graft copolymer used as the raw materials therefor are provided, where the polyorganosiloxane latex has a mass average particle diameter (Dw) of a polyorganosiloxane particle of 100 to 200 nm, and a ratio of the mass average particle diameter (Dw) to a number average particle diameter (Dn) (Dw/Dn) of 1.0 to 1.7. A polyorganosiloxane-containing vinyl-based copolymer (g) obtained by polymerizing one or more vinyl-based monomers in the presence of the latex. A graft copolymer (G) is obtained by graft polymerizing one or more vinyl-based monomers in the presence of the copolymer. A thermoplastic resin composition includes the graft copolymer (G) and a thermoplastic resin (Ha) except for the graft copolymer (G). A molded body is obtained by molding the resin composition.

A laser welding material and laser welding method which can satisfactorily weld resin members of different resin materials that have no or little adhesive property is provided and includes a set of resin materials constituting a first resin member, a second resin member and a third resin member in which the first resin member and the second resin member are different materials and the first resin member does not absorb laser light and which is used for laser-welding the three members by overlapping the third resin member with the first and second resin members and irradiating laser light to the three members from the first resin member side, and a layer welding method.
