Step 410 provides a release layer and a colloidal silica, wherein the colloidal silica comprises a silica gel material, and the release layer selectively comprises a three-dimensional microstructure.
Step 420 is to form a protection layer on the release layer, and a UV curable material or a thermosetting material is used as the protection layer.
Step 430 forms a decorative layer on the protective layer, and forms an adhesion layer on the decorative layer, the adhesion layer comprising a thermoplastic material.
Step 440 coats a primer layer on the adhesion layer, the primer layer including functional groups similar to the thermoplastic material and the colloidal silica material, respectively, for providing a bridging reaction between the adhesion layer and the colloidal silica.
Step 460 removes the release layer from the silicone body to expose the passivation layer.
Step 470 is to selectively irradiate the protective layer with UV light, such as UV curable material, to ensure complete curing of the UV protective layer.
