A transfer film including a substrate, a protection layer, a metal coating layer, and an ink layer is provided. The substrate has a first surface and a second surface, and the first surface has a first stereoscopic pattern. The protection layer is disposed on the substrate, and has a third surface and a fourth surface. The third surface contacts the first surface, and has a second stereoscopic pattern complementing the first stereoscopic pattern. The fourth surface has a third stereoscopic pattern. The metal coating layer is disposed on the protection layer, and has a fifth surface contacting the fourth surface and a sixth surface. The ink layer is disposed on the metal coating layer. The protection layer and the substrate are separated after transfer to expose the second stereoscopic pattern and reflect out the third stereoscopic pattern. A manufacturing method of the transfer film is also provided.

Transfer film

A production method of workpiece is provided. First, an adhesive layer is applied on a workpiece, wherein a material of the adhesive layer includes thermosetting resin and radiationcurable resin. The adhesive layer is impressed by a mold, so that the adhesive layer forms a three-dimensional pattern. A first curing process is performed on the adhesive layer by one of radiation-curing and thermal-curing. The workpiece is punched after the first curing process is performed on the adhesive layer, so that the workpiece forms a three-dimensional workpiece. A second curing process is performed on the adhesive layer by another one of radiation-curing and thermal-curing after the workpiece is punched. In addition, a workpiece with three-dimensional pattern is also provided.

Production method of workpiece and workpiece with three-dimensional pattern

A composite light guide plate manufacturing method includes the steps of providing a light guide substrate; providing a transfer membrane, which sequentially includes a substrate, a reflective layer and a diffusion microstructure; attaching the transfer membrane to the light guide substrate with a side of the transfer membrane, which has the diffusion microstructure thereon; and removing the substrate to expose the reflective layer.
