Abstract:
A method of manufacturing a laser laminar structure, comprising steps of:using a molding resin material to coat at least one of two sides of a thin substrate to form a molding resin layer, so that said molding resin layer is bonded to said thin substrate; attaching a transparent laser film to an outer surface of said molding resin layer, and said transparent laser film being provided with a laser-processed image containing a plurality of fine grooves to show desired figures, characters or logos; allowing said molding resin material at a superficial portion of said molding resin layer to enter said fine grooves on said transparent laser film through inherent surface tension and bonding ability of said molding resin material, so that primary fine lines corresponding to said fine grooves are formed on said outer surface of said molding resin layer to present a laser image corresponding to said image provided on said transparent laser film; subjecting said molding resin layer to baking at high temperature, so that said primary fine lines on said outer surface of said molding resin layer are hardened into a fixed superficial contour; and releasing said transparent laser film from said molding resin layer to provide a laser laminar structure that is capable of enduring high temperature required in subsequent processing of said laser laminar structure.
