<P>PROBLEM TO BE SOLVED: To provide a resin label which can be stuck to a resin molding according to a convenient method without using a adhesive. <P>SOLUTION: A label for laser transmission welding label comprises at least a resin layer and is a resin label for being bonded to a resin molding according to laser welding, wherein the resin layer exhibits a permeability of 20% or higher for laser beams, having an oscillation wavelength within a range of 740 to 1,100 nm wavelength, exhibiting total light transmittance (measured in compliance with ASTM D1003) of 50% or below for visible light, and has light-scattering properties. The resin layer can be constituted of a thermoplastic resin, and the thermoplastic resin may have compatibility with resins constituting the resin molding. The label may be one, capable of concealing the resin molding and may be colored with a colorant, etc. Further, a composite molding such as toner cartridge may be formed, by bonding the label to the resin molding according to laser welding. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
