Abstract
A laser laminar structure is formed by coating each side of a thin substrate with a bonding resin layer, and then coating each bonding resin layer with a molding resin layer; attaching a transparent laser film provided with fine grooves of a laser image presenting figure, characters or logos to an outer surface of each molding resin layer, so that each molding resin layer is formed at superficial portion with fine lines corresponding to the fine grooves of the laser image on the laser film; baking the molding resin layers at high temperature to harden the fine lines formed thereon; and releasing the transparent laser films from the molding resin layers to provide a thermostable laser laminar structure.
